Opdivo Qvantig

Description for Opdivo Qvantig

OPDIVO QVANTIG is a fixed-combination drug product containing nivolumab and hyaluronidase (human recombinant).

Nivolumab is a programmed death receptor-1 (PD-1) blocking antibody. Nivolumab is an IgG4 kappa immunoglobulin that has a calculated molecular mass of 146 kDa. It is expressed in a recombinant Chinese Hamster Ovary (CHO) cell line.

Hyaluronidase (human recombinant) is an endoglycosidase used to increase the dispersion and absorption of co-administered drugs when administered subcutaneously.

Hyaluronidase (human recombinant) is a glycosylated single-chain protein produced by CHO cells containing a DNA plasmid encoding for a soluble fragment of human hyaluronidase (PH20). Hyaluronidase (human recombinant) has a molecular weight of approximately 61 kDa.

OPDIVO QVANTIG (nivolumab and hyaluronidase-nvhy) injection is a sterile, preservativefree, clear to opalescent, colorless to yellow solution, that may contain a few translucentto- white particles, supplied in a single-dose vial for subcutaneous use.

Each 5 mL single-dose vial of OPDIVO QVANTIG contains 600 mg of nivolumab and 10,000 units of hyaluronidase (human recombinant), and the inactive ingredients: histidine (7.75 mg), histidine hydrochloride monohydrate (10.5 mg), methionine (3.73 mg), pentetic acid (0.0985 mg), polysorbate 80 (2.5 mg), sucrose (428 mg), and Water for Injection, USP.

Preparation And Administration

To prevent medication errors, check the vial labels to ensure that the drug being prepared and administered is OPDIVO QVANTIG for subcutaneous use and NOT intravenous nivolumab. Do NOT administer OPDIVO QVANTIG intravenously. OPDIVO QVANTIG should be administered by a healthcare professional.

Each OPDIVO QVANTIG vial is for one-time use only. It is a ready-to-use solution for injection. It should not be diluted.

Visually inspect for particulate matter and discoloration prior to administration. OPDIVO QVANTIG is a clear to opalescent, colorless to yellow solution. Discard if the solution is discolored or contains extraneous particulate matter other than a few translucent-towhite particles. Do not shake.

Preparation

No incompatibilities were observed between OPDIVO QVANTIG and polypropylene and polycarbonate syringes, or between OPDIVO QVANTIG and polyethylene, polyurethane, polyvinyl chloride, and fluorinated ethylene propylene subcutaneous administration sets.

A syringe and a transfer needle are needed to withdraw OPDIVO QVANTIG solution from the vial. OPDIVO QVANTIG may be injected subcutaneously using a 23G-25G (3/8”-5/8”) hypodermic injection needle or subcutaneous administration set (eg., winged/butterfly).

• 600 mg nivolumab and 10,000 units hyaluronidase
  • Allow 1 OPDIVO QVANTIG vial to reach room temperature, then withdraw 5 mL of OPDIVO QVANTIG into the syringe.
• 900 mg nivolumab and 15,000 units hyaluronidase
  • Allow 2 OPDIVO QVANTIG vials to reach room temperature, then withdraw 5 mL from one vial and 2.5 mL from the other vial, for a total volume of 7.5 mL of OPDIVO QVANTIG into a single syringe.
• 1,200 mg nivolumab and 20,000 units hyaluronidase
  • Allow 2 OPDIVO QVANTIG vials to reach room temperature, then withdraw 10 mL of OPDIVO QVANTIG into a single syringe.

Select the appropriate syringe label provided in the carton that matches the prescribed dose and apply to the prepared syringe.

Discard partially used or empty vials of OPDIVO QVANTIG.

If the dose is not to be used immediately, attach a tip cap to the syringe prior to storage. To avoid clogging of the hypodermic injection needle, attach a 23G-25G (3/8”-5/8”) hypodermic injection needle to the syringe immediately prior to administration.

Storage In Syringe

Once withdrawn into the syringe, OPDIVO QVANTIG should be used immediately. If not used immediately, store the syringe:

• In the refrigerator at 2°C to 8°C (36°F to 46°F), protected from light for up to 48 hours; do not freeze, or
• At room temperature 20°C to 25°C (68°F to 77°F) for up to 8 hours. Storage at room temperature for this duration does not require protection from light.
• Discard if storage time exceeds these limits.
• If stored in the refrigerator, allow the solution to come to room temperature before administration.

Administration

• Administer the full contents of the syringe into the subcutaneous tissue of 1 of the 4 quadrants of the abdomen, or thigh over a period of 3 to 5 minutes.
• Alternate injection sites across the 4 quadrants of the abdomen or thighs for successive injections. Do not inject into areas where the skin is tender, red, or bruised, or areas where there are scars or moles. If the administration of OPDIVO QVANTIG is interrupted, continue administering at the same site, or at an alternate site.
• During treatment with OPDIVO QVANTIG, do not administer other subcutaneous medications at the same site used for OPDIVO QVANTIG.

Adverse Reactions In Patients Treated With Intravenous Nivolumab

The safety of OPDIVO QVANTIG for its approved indications [see INDICATIONS AND USAGE] has been established in adequate and well-controlled clinical studies of intravenous nivolumab. Below is a description of adverse reactions in these adequate and well-controlled clinical studies.

First-line Renal Cell Carcinoma

CHECKMATE-214

The safety of intravenous nivolumab with ipilimumab was evaluated in CHECKMATE-214, a randomized open-label trial in 1082 patients with previously untreated advanced RCC; patients received intravenous nivolumab 3 mg/kg over 60 minutes with ipilimumab 1 mg/kg intravenously every 3 weeks for 4 doses followed by intravenous nivolumab as a single agent at a dose of 3 mg/kg by intravenous infusion every 2 weeks (n=547) or sunitinib 50 mg orally daily for the first 4 weeks of a 6-week cycle (n=535) [see Clinical Studies]. The median duration of treatment was 7.9 months (range: 1 day to 21.4+ months) in intravenous nivolumab and ipilimumab-treated patients and 7.8 months (range: 1 day to 20.2+ months) in sunitinib-treated patients. In this trial, 57% of patients in the intravenous nivolumab and ipilimumab arm were exposed to treatment for >6 months and 38% of patients were exposed to treatment for >1 year.

Serious adverse reactions occurred in 59% of patients receiving intravenous nivolumab and ipilimumab. Study therapy was discontinued for adverse reactions in 31% of intravenous nivolumab and ipilimumab patients. Fifty-four percent (54%) of patients receiving intravenous nivolumab and ipilimumab had a dose interruption for an adverse reaction.

The most frequent serious adverse reactions reported in ≥2% of patients treated with intravenous nivolumab and ipilimumab were diarrhea, pyrexia, pneumonia, pneumonitis, hypophysitis, acute kidney injury, dyspnea, adrenal insufficiency, and colitis; in patients treated with sunitinib, they were pneumonia, pleural effusion, and dyspnea. The most common adverse reactions (reported in ≥20% of patients) were fatigue, rash, diarrhea, musculoskeletal pain, pruritus, nausea, cough, pyrexia, arthralgia, and decreased appetite. The most common laboratory abnormalities which have worsened compared to baseline in ≥30% of intravenous nivolumab and ipilimumab-treated patients include increased lipase, anemia, increased creatinine, increased ALT, increased AST, hyponatremia, increased amylase, and lymphopenia.

Tables 7 and 8 summarize adverse reactions and laboratory abnormalities, respectively, that occurred in >15% of intravenous nivolumab and ipilimumab-treated patients in CHECKMATE-214.

In addition, among patients with TSH ≤ ULN at baseline, a lower proportion of patients experienced a treatment-emergent elevation of TSH > ULN in the intravenous nivolumab and ipilimumab group compared to the sunitinib group (31% and 61%, respectively).

CHECKMATE-9ER

The safety of intravenous nivolumab with cabozantinib was evaluated in CHECKMATE-9ER, a randomized, open-label study in patients with previously untreated advanced RCC. Patients received intravenous nivolumab 240 mg over 30 minutes every 2 weeks with cabozantinib 40 mg orally once daily (n=320) or sunitinib 50 mg daily, administered orally for 4 weeks on treatment followed by 2 weeks off (n=320) [see Clinical Studies]. Cabozantinib could be interrupted or reduced to 20 mg daily or 20 mg every other day. The median duration of treatment was 14 months (range: 0.2 to 27 months) in intravenous nivolumab and cabozantinib-treated patients. In this trial, 82% of patients in the intravenous nivolumab and cabozantinib arm were exposed to treatment for >6 months and 60% of patients were exposed to treatment for >1 year.

Serious adverse reactions occurred in 48% of patients receiving intravenous nivolumab and cabozantinib. The most frequent (≥2%) serious adverse reactions were diarrhea, pneumonia, pneumonitis, pulmonary embolism, urinary tract infection, and hyponatremia. Fatal intestinal perforations occurred in 3 (0.9%) patients.

Adverse reactions leading to discontinuation of either intravenous nivolumab or cabozantinib occurred in 20% of patients: 7% intravenous nivolumab only, 8% cabozantinib only, and 6% both drugs due to same adverse reaction at the same time. Adverse reaction leading to dose interruption or reduction of either intravenous nivolumab or cabozantinib occurred in 83% of patients: 3% intravenous nivolumab only, 46% cabozantinib only, and 21% both drugs due to same adverse reaction at the same time, and 6% both drugs sequentially.

The most common adverse reactions reported in ≥20% of patients treated with intravenous nivolumab and cabozantinib were diarrhea, fatigue, hepatotoxicity, palmar-plantar erythrodysesthesia syndrome, stomatitis, rash, hypertension, hypothyroidism, musculoskeletal pain, decreased appetite, nausea, dysgeusia, abdominal pain, cough, and upper respiratory tract infection.

Previously Treated Renal Cell Carcinoma

CHECKMATE-025

The safety of intravenous nivolumab was evaluated in CHECKMATE-025, a randomized open-label trial in 803 patients with advanced RCC who had experienced disease progression during or after at least one anti-angiogenic treatment regimen received intravenous nivolumab 3 mg/kg over 60 minutes by intravenous infusion every 2 weeks (n=406) or everolimus 10 mg daily (n=397) [see Clinical Studies]. The median duration of treatment was 5.5 months (range: 1 day to 29.6+ months) in intravenous nivolumab-treated patients and 3.7 months (range: 6 days to 25.7+ months) in everolimus-treated patients.

Rate of death on treatment or within 30 days of the last dose was 4.7% on the intravenous nivolumab arm. Serious adverse reactions occurred in 47% of patients receiving intravenous nivolumab. Study therapy was discontinued for adverse reactions in 16% of intravenous nivolumab patients. Forty-four percent (44%) of patients receiving intravenous nivolumab had a dose interruption for an adverse reaction.

The most frequent serious adverse reactions in at least 2% of patients were: acute kidney injury, pleural effusion, pneumonia, diarrhea, and hypercalcemia. The most common adverse reactions (≥20%) were fatigue, cough, nausea, rash, dyspnea, diarrhea, constipation, decreased appetite, back pain, and arthralgia. The most common laboratory abnormalities which have worsened compared to baseline in ≥30% of patients include increased creatinine, lymphopenia, anemia, increased AST, increased alkaline phosphatase, hyponatremia, increased triglycerides, and hyperkalemia. In addition, among patients with TSH < ULN at baseline, a greater proportion of patients experienced a treatment-emergent elevation of TSH > ULN in the intravenous nivolumab group compared to the everolimus group (26% and 14%, respectively).

Unresectable Or Metastatic Melanoma

Previously Treated Metastatic Melanoma

CHECKMATE-037

The safety of intravenous nivolumab was evaluated in CHECKMATE-037, a randomized, open-label trial in 370 patients with unresectable or metastatic melanoma [see Clinical Studies]. Patients had documented disease progression following treatment with ipilimumab and, if BRAF V600 mutation positive, a BRAF inhibitor. The trial excluded patients with autoimmune disease, prior ipilimumab-related Grade 4 adverse reactions (except for endocrinopathies) or Grade 3 ipilimumab-related adverse reactions that had not resolved or were inadequately controlled within 12 weeks of the initiating event, patients with a condition requiring chronic systemic treatment with corticosteroids (>10 mg daily prednisone equivalent) or other immunosuppressive medications, a positive test for hepatitis B or C, and a history of HIV. Patients received intravenous nivolumab 3 mg/kg by intravenous infusion over 60 minutes every 2 weeks (n=268) or investigator’s choice of chemotherapy (n=102): dacarbazine 1000 mg/m² intravenously every 3 weeks or carboplatin AUC 6 mg/mL/min and paclitaxel 175 mg/m² intravenously every 3 weeks. The median duration of exposure was 5.3 months (range: 1 day to 13.8+ months) in intravenous nivolumab-treated patients and was 2 months (range: 1 day to 9.6+ months) in chemotherapy-treated patients. In this ongoing trial, 24% of patients received intravenous nivolumab for >6 months and 3% of patients received intravenous nivolumab for >1 year.

The population characteristics in the intravenous nivolumab group and the chemotherapy group were similar: 66% male, median age 59.5 years, 98% White, baseline Eastern Cooperative Oncology Group (ECOG) performance status 0 (59%) or 1 (41%), 74% with M1c stage disease, 73% with cutaneous melanoma, 11% with mucosal melanoma, 73% received two or more prior therapies for advanced or metastatic disease, and 18% had brain metastasis. There were more patients in the intravenous nivolumab group with elevated lactate dehydrogenase (LDH) at baseline (51% vs. 38%).

Serious adverse reactions occurred in 41% of patients receiving intravenous nivolumab. Intravenous nivolumab was discontinued for adverse reactions in 9% of patients. Twenty-six percent of patients receiving intravenous nivolumab had a dose interruption for an adverse reaction. Grade 3 and 4 adverse reactions occurred in 42% of patients receiving intravenous nivolumab. The most frequent Grade 3 and 4 adverse reactions reported in 2% to <5% of patients receiving intravenous nivolumab were abdominal pain, hyponatremia, increased aspartate aminotransferase, and increased lipase. The most common adverse reaction (reported in ≥20% of patients) was rash.

Tables 13 and 14 summarize the adverse reactions and laboratory abnormalities, respectively, in CHECKMATE-037.

Previously Untreated Metastatic Melanoma

CHECKMATE-066

The safety of intravenous nivolumab was also evaluated in CHECKMATE-066, a randomized, double-blind, active-controlled trial in 411 previously untreated patients with BRAF V600 wild-type unresectable or metastatic melanoma [see Clinical Studies]. The trial excluded patients with autoimmune disease and patients requiring chronic systemic treatment with corticosteroids (>10 mg daily prednisone equivalent) or other immunosuppressive medications. Patients received intravenous nivolumab 3 mg/kg by intravenous infusion over 60 minutes every 2 weeks (n=206) or dacarbazine 1000 mg/m² intravenously every 3 weeks (n=205). The median duration of exposure was 6.5 months (range: 1 day to 16.6 months) in intravenous nivolumab-treated patients. In this trial, 47% of patients received intravenous nivolumab for >6 months and 12% of patients received intravenous nivolumab for >1 year.

The trial population characteristics in the intravenous nivolumab group and dacarbazine group: 59% male, median age 65 years, 99.5% White, 61% with M1c stage disease, 74% with cutaneous melanoma, 11% with mucosal melanoma, 4% with brain metastasis, and 37% with elevated LDH at baseline. There were more patients in the intravenous nivolumab group with ECOG performance status 0 (71% vs. 59%).

Serious adverse reactions occurred in 36% of patients receiving intravenous nivolumab. Adverse reactions led to permanent discontinuation of intravenous nivolumab in 7% of patients and dose interruption in 26% of patients; no single type of adverse reaction accounted for the majority of intravenous nivolumab discontinuations. Grade 3 and 4 adverse reactions occurred in 41% of patients receiving intravenous nivolumab.

The most frequent Grade 3 and 4 adverse reactions reported in ≥2% of patients receiving intravenous nivolumab were increased gamma-glutamyl transferase (3.9%) and diarrhea (3.4%). The most common adverse reactions (reported in ≥20% of patients and at a higher incidence than in the dacarbazine arm) were fatigue, musculoskeletal pain, rash, and pruritus.

CHECKMATE-067

The safety of intravenous nivolumab, administered with ipilimumab or as a single agent, was evaluated in CHECKMATE-067, a randomized (1:1:1), double-blind trial in 937 patients with previously untreated, unresectable or metastatic melanoma [see Clinical Studies]. The trial excluded patients with autoimmune disease, a medical condition requiring systemic treatment with corticosteroids (more than 10 mg daily prednisone equivalent) or other immunosuppressive medication within 14 days of the start of study therapy, a positive test result for hepatitis B or C, or a history of HIV.

Patients were randomized to receive:

• Intravenous nivolumab 1 mg/kg over 60 minutes with ipilimumab 3 mg/kg by intravenous infusion every 3 weeks for 4 doses followed by intravenous nivolumab as a single agent at a dose of 3 mg/kg by intravenous infusion over 60 minutes every 2 weeks (nivolumab and ipilimumab arm; n=313), or
• Intravenous nivolumab 3 mg/kg by intravenous infusion over 60 minutes every 2 weeks (nivolumab arm; n=313), or
• Ipilimumab 3 mg/kg by intravenous infusion every 3 weeks for up to 4 doses (ipilimumab arm; n=311).

The median duration of exposure to intravenous nivolumab was 2.8 months (range: 1 day to 36.4 months) for the intravenous nivolumab and ipilimumab arm and 6.6 months (range: 1 day to 36.0 months) for the intravenous nivolumab arm. In the intravenous nivolumab and ipilimumab arm, 39% were exposed to intravenous nivolumab for ≥6 months and 30% exposed for >1 year. In the intravenous nivolumab arm, 53% were exposed for ≥6 months and 40% for >1 year.

The population characteristics were: 65% male, median age 61 years, 97% White, baseline ECOG performance status 0 (73%) or 1 (27%), 93% with American Joint Committee on Cancer (AJCC) Stage IV disease, 58% with M1c stage disease; 36% with elevated LDH at baseline, 4% with a history of brain metastasis, and 22% had received adjuvant therapy.

Serious adverse reactions (74% and 44%), adverse reactions leading to permanent discontinuation (47% and 18%) or to dosing delays (58% and 36%), and Grade 3 or 4 adverse reactions (72% and 51%) all occurred more frequently in the intravenous nivolumab and ipilimumab arm relative to the intravenous nivolumab arm.

The most frequent (≥10%) serious adverse reactions in the intravenous nivolumab and ipilimumab arm and the intravenous nivolumab arm, respectively, were diarrhea (13% and 2.2%), colitis (10% and 1.9%), and pyrexia (10% and 1%). The most frequent adverse reactions leading to discontinuation of both drugs in the intravenous nivolumab and ipilimumab arm and of intravenous nivolumab in the intravenous nivolumab arm, respectively, were colitis (10% and 0.6%), diarrhea (8% and 2.2%), increased ALT (4.8% and 1%), increased AST (4.5% and 0.6%), and pneumonitis (1.9% and 0.3%).

The most common (≥20%) adverse reactions in the intravenous nivolumab and ipilimumab arm were fatigue, diarrhea, rash, nausea, pyrexia, pruritus, musculoskeletal pain, vomiting, decreased appetite, cough, headache, dyspnea, upper respiratory tract infection, arthralgia, and increased transaminases.

Adjuvant Treatment Of Melanoma

CHECKMATE-76K

The safety of intravenous nivolumab as a single agent was evaluated in CHECKMATE-76K, a randomized (2:1), double-blind trial in 788 patients with completely resected Stage IIB/C melanoma who received intravenous nivolumab 480 mg by intravenous infusion over 30 minutes every 4 weeks (n=524) or placebo by intravenous infusion over 30 minutes every 4 weeks (n=264) for up to 1 year [see Clinical Studies]. The median duration of exposure was 11 months in patients treated with intravenous nivolumab and 11 months in patients treated with placebo.

Serious adverse reactions occurred in 18% of patients treated with intravenous nivolumab. A fatal adverse reaction occurred in 1 (0.2%) patient (heart failure and acute kidney injury). Permanent discontinuation of intravenous nivolumab due to an adverse reaction occurred in 17% of patients. Adverse reactions which resulted in permanent discontinuation of intravenous nivolumab in >1% of patients included diarrhea (1.1%), arthralgia (1.7%), and rash (1.7%).

Dosage interruptions of intravenous nivolumab due to an adverse reaction occurred in 25% of patients. Adverse reactions which required dosage interruption in >1% of patients included COVID-19 infection, infusion related reaction, diarrhea, arthralgia, and increased ALT.

The most common adverse reactions (reported in ≥20% of patients) were fatigue, musculoskeletal pain, rash, diarrhea, and pruritus.

Neoadjuvant And Adjuvant Treatment Of Resectable (Tumors ≥4 cm or Node Positive) Non-Small Cell Lung Cancer

CHECKMATE-77T

The safety of intravenous nivolumab in combination with neoadjuvant platinum-doublet chemotherapy followed by surgery and continued adjuvant treatment with intravenous nivolumab as a single agent after surgery was evaluated in CHECKMATE-77T, a randomized, double-blind, multicenter trial in patients with previously untreated resectable Stage IIA (>4 cm) to IIIB (T3N2 or T4N2) NSCLC (per the AJCC Cancer Staging Manual 8th Edition) [see Clinical Studies]. Patients with active autoimmune disease or a medical condition that required immunosuppression were ineligible. The median duration of exposure to intravenous nivolumab was 10.3 months (range: 1 day to 22.3 months).

The study population characteristics were: median age 66 years (range: 35 - 86); 71% male; 72% White, 25% Asian, 1.7% Black/African American, and 1.5% other race; and 6% Hispanic or Latino.

Adverse reactions occurring in patients with resectable NSCLC receiving intravenous nivolumab in combination with platinum-doublet chemotherapy, given as neoadjuvant treatment and followed as a single agent adjuvant treatment after surgery, were generally similar to those occurring in patients in other clinical trials across tumor types receiving intravenous nivolumab in combination with chemotherapy.

Neoadjuvant Phase Of CHECKMATE-77T

A total of 228 patients received at least 1 dose of intravenous nivolumab in combination with platinum-doublet chemotherapy as neoadjuvant treatment and 230 patients received at least 1 dose of placebo in combination with platinum-doublet chemotherapy as neoadjuvant treatment.

Serious adverse reactions occurred in 21% of patients who received intravenous nivolumab in combination with platinum-doublet chemotherapy as neoadjuvant treatment; the most frequent (≥2%) serious adverse reactions was pneumonia. Fatal adverse reactions occurred in 2.2% of patients, due to cerebrovascular accident, COVID-19 infection, hemoptysis, pneumonia, and pneumonitis (0.4% each).

Permanent discontinuation of any study drug due to an adverse reaction occurred in 13% of patients who received intravenous nivolumab in combination with platinum-doublet chemotherapy as neoadjuvant treatment; the most frequent (≥1%) adverse reaction that led to permanent discontinuation of any study drug was peripheral sensory neuropathy (2.2%).

Of the 228 intravenous nivolumab-treated patients and 230 placebo-treated patients who received neoadjuvant treatment, 5.3% (n=12) and 3.5% (n=8), respectively, did not receive surgery due to adverse reactions. The adverse reactions that led to cancellation of surgery in intravenous nivolumab-treated patients were cerebrovascular accident, pneumonia, and colitis/diarrhea (2 patients each) and acute coronary syndrome, myocarditis, hemoptysis, pneumonitis, COVID-19, and myositis (1 patient each).

Of the 178 intravenous nivolumab-treated patients who received surgery, 4.5% (n=8) experienced delay of surgery (surgery more than 6 weeks from last neoadjuvant treatment) due to adverse reactions. Of the 178 placebo-treated patients who received surgery, 3.9% (n=7) experienced delay of surgery due to adverse reactions.

Of the 178 intravenous nivolumab-treated patients who received surgery, 7% (n=13) did not receive adjuvant treatment due to adverse reactions. Of the 178 placebo-treated patients who received surgery, 2.8% (n=5) did not receive adjuvant treatment due to adverse reactions.

Adjuvant Phase Of CHECKMATE-77T

A total of 142 patients in the intravenous nivolumab arm and 152 patients in the placebo arm received at least 1 dose of adjuvant treatment.

Of the patients who received single agent intravenous nivolumab as adjuvant treatment, 22% experienced serious adverse reactions; the most frequent serious adverse reaction was pneumonitis/ILD (2.8%). One fatal adverse reaction due to COVID-19 occurred. Permanent discontinuation of adjuvant intravenous nivolumab due to an adverse reaction occurred in 14% of patients; the most frequent (≥1%) adverse reactions that led to permanent discontinuation of adjuvant intravenous nivolumab were pneumonitis (4.2%) and diarrhea (1.4%).

Second-line Treatment Of Metastatic NSCLC

CHECKMATE-017 and CHECKMATE-057

The safety of intravenous nivolumab was evaluated in CHECKMATE-017, a randomized open-label, multicenter trial in patients with metastatic squamous NSCLC and progression on or after one prior platinum doublet-based chemotherapy regimen and in CHECKMATE-057, a randomized, open-label, multicenter trial in patients with metastatic non-squamous NSCLC and progression on or after one prior platinum doublet-based chemotherapy regimen [see Clinical Studies]. These trials excluded patients with active autoimmune disease, medical conditions requiring systemic immunosuppression, or with symptomatic interstitial lung disease. Patients received intravenous nivolumab 3 mg/kg over 60 minutes by intravenous infusion every 2 weeks or docetaxel 75 mg/m² intravenously every 3 weeks. The median duration of therapy in intravenous nivolumabtreated patients in CHECKMATE-017 was 3.3 months (range: 1 day to 21.7+ months) and in CHECKMATE-057 was 2.6 months (range: 0 to 24.0+ months). In CHECKMATE-017, 36% of patients received intravenous nivolumab for at least 6 months and 18% of patients received intravenous nivolumab for at least 1 year and in CHECKMATE-057, 30% of patients received intravenous nivolumab for >6 months and 20% of patients received intravenous nivolumab for >1 year.

Across both trials, the median age of intravenous nivolumab-treated patients was 61 years (range: 37 to 85); 38% were ≥65 years of age, 61% were male, and 91% were White. Ten percent of patients had brain metastases and ECOG performance status was 0 (26%) or 1 (74%).

In CHECKMATE-057, in the intravenous nivolumab arm, seven deaths were due to infection including one case of Pneumocystis jirovecii pneumonia, four were due to pulmonary embolism, and one death was due to limbic encephalitis. Serious adverse reactions occurred in 46% of patients receiving intravenous nivolumab. Intravenous nivolumab was discontinued in 11% of patients and was delayed in 28% of patients for an adverse reaction.

The most frequent serious adverse reactions reported in ≥2% of patients receiving intravenous nivolumab were pneumonia, pulmonary embolism, dyspnea, pyrexia, pleural effusion, pneumonitis, and respiratory failure. Across both trials, the most common adverse reactions (≥20%) were fatigue, musculoskeletal pain, cough, dyspnea, and decreased appetite.

Tables 25 and 26 summarize selected adverse reactions and laboratory abnormalities, respectively, in CHECKMATE-057.

Squamous Cell Carcinoma Of The Head And Neck

CHECKMATE-141

The safety of intravenous nivolumab was evaluated in CHECKMATE-141, a randomized, active-controlled, open-label, multicenter trial in patients with recurrent or metastatic SCCHN with progression during or within 6 months of receiving prior platinum-based therapy [see Clinical Studies]. The trial excluded patients with active autoimmune disease, medical conditions requiring systemic immunosuppression, or recurrent or metastatic carcinoma of the nasopharynx, squamous cell carcinoma of unknown primary histology, salivary gland or non-squamous histologies (e.g., mucosal melanoma). Patients received intravenous nivolumab 3 mg/kg by intravenous infusion over 60 minutes every 2 weeks (n=236) or investigator’s choice of either cetuximab (400 mg/m² initial dose intravenously followed by 250 mg/m² weekly), or methotrexate (40 to 60 mg/m² intravenously weekly), or docetaxel (30 to 40 mg/m² intravenously weekly). The median duration of exposure to nivolumab was 1.9 months (range: 1 day to 16.1+ months) in intravenous nivolumab-treated patients. In this trial, 18% of patients received intravenous nivolumab for >6 months and 2.5% of patients received intravenous nivolumab for >1 year.

The median age of all randomized patients was 60 years (range: 28 to 83); 28% of patients in the intravenous nivolumab group were ≥65 years of age and 37% in the comparator group were ≥65 years of age, 83% were male and 83% were White, 12% were Asian, and 4% were Black. Baseline ECOG performance status was 0 (20%) or 1 (78%), 45% of patients received only one prior line of systemic therapy, the remaining 55% of patients had two or more prior lines of therapy, and 90% had prior radiation therapy.

Serious adverse reactions occurred in 49% of patients receiving intravenous nivolumab. Intravenous nivolumab was discontinued in 14% of patients and was delayed in 24% of patients for an adverse reaction. Adverse reactions and laboratory abnormalities occurring in patients with SCCHN were generally similar to those occurring in patients with melanoma and NSCLC.

The most frequent serious adverse reactions reported in ≥2% of patients receiving intravenous nivolumab were pneumonia, dyspnea, respiratory failure, respiratory tract infection, and sepsis. The most common adverse reactions occurring in ≥10% of intravenous nivolumab-treated patients and at a higher incidence than investigator’s choice were cough and dyspnea. The most common laboratory abnormalities occurring in ≥10% of intravenous nivolumab-treated patients and at a higher incidence than investigator’s choice were increased alkaline phosphatase, increased amylase, hypercalcemia, hyperkalemia, and increased TSH.

First-line Treatment Of Unresectable Or Metastatic UC

CHECKMATE-901

The safety of intravenous nivolumab was evaluated in CHECKMATE-901, a randomized, open-label trial in cisplatin-eligible patients with unresectable or metastatic UC [see Clinical Studies]. Patients received either intravenous nivolumab 360 mg with cisplatin and gemcitabine every 3 weeks for up to 6 cycles followed by single-agent intravenous nivolumab 480 mg every 4 weeks up to 2 years (n=304), or cisplatin and gemcitabine chemotherapy every 3 weeks for up to 6 cycles (n=288). Patients discontinuing cisplatin alone were permitted to switch to carboplatin.

Among patients who received intravenous nivolumab with chemotherapy, the median duration of intravenous nivolumab exposure was 7.4 months (range: 0.03 to 47.9 months). Serious adverse reactions occurred in 48% of patients receiving intravenous nivolumab in combination with chemotherapy. The most frequent serious adverse reactions reported in ≥2% of patients who received intravenous nivolumab with chemotherapy were urinary tract infection (4.9%), acute kidney injury (4.3%), anemia (3%), pulmonary embolism (2.6%), sepsis (2.3%), and platelet count decreased (2.3%). The most common adverse reactions (reported in ≥20% of patients) were nausea, fatigue, musculoskeletal pain, constipation, decreased appetite, rash, vomiting, and peripheral neuropathy.

Fatal adverse reactions occurred in 3.6% of patients who received intravenous nivolumab in combination with chemotherapy; these included sepsis (1%).

Intravenous nivolumab and/or chemotherapy were discontinued in 30% of patients and were delayed in 67% of patients for an adverse reaction.

Tables 29 and 30 summarize the adverse reactions and laboratory abnormalities, respectively, in CHECKMATE-901.

Previously Treated Advanced Or Metastatic UC

CHECKMATE-275

The safety of intravenous nivolumab was evaluated in CHECKMATE-275, a single arm trial in which 270 patients with locally advanced or metastatic UC had disease progression during or following platinum-containing chemotherapy or had disease progression within 12 months of neoadjuvant or adjuvant treatment with platinumcontaining chemotherapy [see Clinical Studies]. Patients received intravenous nivolumab 3 mg/kg by intravenous infusion over 60 minutes every 2 weeks until disease progression or unacceptable toxicity. The median duration of treatment was 3.3 months (range: 0 to 13.4+). Forty-six percent (46%) of patients had a dose interruption for an adverse reaction.

Fourteen patients (5.2%) died from causes other than disease progression. This includes 4 patients (1.5%) who died from pneumonitis or cardiovascular failure which was attributed to treatment with intravenous nivolumab. Serious adverse reactions occurred in 54% of patients. Intravenous nivolumab was discontinued for adverse reactions in 17% of patients.

The most frequent serious adverse reactions reported in ≥2% of patients were urinary tract infection, sepsis, diarrhea, small intestine obstruction, and general physical health deterioration. The most common adverse reactions (reported in ≥20% of patients) were fatigue, musculoskeletal pain, nausea, and decreased appetite.

Tables 31 and 32 summarize adverse reactions and laboratory abnormalities, respectively, in CHECKMATE-275.

MSI-H Or dMMR Metastatic Colorectal Cancer

CHECKMATE-142

The safety of intravenous nivolumab administered as a single agent or in combination with ipilimumab was evaluated in CHECKMATE-142, a multicenter, non-randomized, multiple parallel-cohort, open-label trial [see Clinical Studies]. In CHECKMATE-142, 74 patients with mCRC received intravenous nivolumab 3 mg/kg by intravenous infusion over 60 minutes every 2 weeks until disease progression or until intolerable toxicity and 119 patients with mCRC received intravenous nivolumab 3 mg/kg and ipilimumab 1 mg/kg every 3 weeks for 4 doses, then intravenous nivolumab 3 mg/kg every 2 weeks until disease progression or until unacceptable toxicity.

In the intravenous nivolumab with ipilimumab cohort, serious adverse reactions occurred in 47% of patients. Treatment was discontinued in 13% of patients and delayed in 45% of patients for an adverse reaction. The most frequent serious adverse reactions reported in ≥2% of patients were colitis/diarrhea, hepatic events, abdominal pain, acute kidney injury, pyrexia, and dehydration. The most common adverse reactions (reported in ≥20% of patients) were fatigue, diarrhea, pyrexia, musculoskeletal pain, abdominal pain, pruritus, nausea, rash, decreased appetite, and vomiting.

Tables 33 and 34 summarize adverse reactions and laboratory abnormalities, respectively, in CHECKMATE-142. Based on the design of CHECKMATE-142, the data below cannot be used to identify statistically significant differences between the two cohorts summarized below for any adverse reaction.

HCV virologic breakthrough was defined as a 1 log increase in HCV RNA from baseline.

Esophageal Cancer

Adjuvant Treatment of Resected Esophageal or Gastroesophageal Junction Cancer

CHECKMATE-577

The safety of intravenous nivolumab was evaluated in CHECKMATE-577, a randomized, placebo-controlled, double-blinded, multicenter trial in 792 treated patients with completely resected (negative margins) esophageal or gastroesophageal junction cancer who had residual pathologic disease following chemoradiotherapy (CRT) [see Clinical Studies]. The trial excluded patients who did not receive concurrent CRT prior to surgery, had stage IV resectable disease, autoimmune disease, or any condition requiring systemic treatment with either corticosteroids (>10 mg daily prednisone or equivalent) or other immunosuppressive medications. Patients received either intravenous nivolumab 240 mg or placebo by intravenous infusion over 30 minutes every 2 weeks for 16 weeks followed by 480 mg or placebo by intravenous infusion over 30 minutes every 4 weeks beginning at week 17. Patients were treated until disease recurrence, unacceptable toxicity, or for up to 1-year total duration. The median duration of exposure was 10.1 months (range: <0.1 to 14 months) in intravenous nivolumabtreated patients and 9 months (range: <0.1 to 15 months) in placebo-treated patients. Among patients who received intravenous nivolumab, 61% were exposed for >6 months and 54% were exposed for >9 months.

Serious adverse reactions occurred in 33% of patients receiving intravenous nivolumab. A serious adverse reaction reported in ≥2% of patients who received intravenous nivolumab was pneumonitis. A fatal adverse reaction of myocardial infarction occurred in one patient who received intravenous nivolumab.

Intravenous nivolumab was discontinued in 12% of patients and was delayed in 28% of patients for an adverse reaction.

First-line Treatment Of Unresectable Advanced Or Metastatic ESCC

CHECKMATE-648

The safety of intravenous nivolumab in combination with chemotherapy or in combination with ipilimumab was evaluated in CHECKMATE-648, a randomized, active-controlled, multicenter, open-label trial in patients with previously untreated unresectable advanced, recurrent or metastatic ESCC [see Clinical Studies]. Patients received one of the following treatments:

• intravenous nivolumab 240 mg on days 1 and 15, 5-FU (fluorouracil) 800 mg/m²/day intravenously on days 1 through 5 (for 5 days), and cisplatin 80 mg/m² intravenously on day 1 (of a 4-week cycle).
• intravenous nivolumab 3 mg/kg every 2 weeks in combination with ipilimumab 1 mg/kg every 6 weeks.
• 5-FU (fluorouracil) 800 mg/m²/day intravenously on days 1 through 5 (for 5 days), and cisplatin 80 mg/m² intravenously on day 1 (of a 4-week cycle).

Among patients who received intravenous nivolumab with chemotherapy, the median duration of exposure was 5.7 months (range: 0.1 to 30.6 months). Among patients who received intravenous nivolumab and ipilimumab, the median duration of exposure was 2.8 months (range: 0 to 24 months).

Serious adverse reactions occurred in 62% of patients receiving intravenous nivolumab in combination with chemotherapy and in 69% of patients receiving intravenous nivolumab in combination with ipilimumab.

Previously-Treated Unresectable Advanced, Recurrent Or Metastatic Esophageal Squamous Cell Carcinoma (ESCC)

ATTRACTION-3

The safety of intravenous nivolumab was evaluated in ATTRACTION-3, a randomized, active-controlled, open-label, multicenter trial in 209 patients with unresectable advanced, recurrent or metastatic ESCC refractory or intolerant to at least one fluoropyrimidineand platinum-based chemotherapy [see Clinical Studies]. The trial excluded patients who were refractory or intolerant to taxane therapy, had brain metastases that were symptomatic or required treatment, had autoimmune disease, used systemic corticosteroids or immunosuppressants, had apparent tumor invasion of organs adjacent to the esophageal tumor or had stents in the esophagus or respiratory tract. Patients received intravenous nivolumab 240 mg by intravenous infusion over 30 minutes every 2 weeks (n=209) or investigator’s choice: docetaxel 75 mg/m² intravenously every 3 weeks (n=65) or paclitaxel 100 mg/m² intravenously once a week for 6 weeks followed by 1 week off (n=143). Patients were treated until disease progression or unacceptable toxicity. The median duration of exposure was 2.6 months (range: 0 to 29.2 months) in intravenous nivolumab-treated patients and 2.6 months (range: 0 to 21.4 months) in docetaxel- or paclitaxel-treated patients. Among patients who received intravenous nivolumab, 26% were exposed for >6 months and 10% were exposed for >1 year.

Serious adverse reactions occurred in 38% of patients receiving intravenous nivolumab. Serious adverse reactions reported in ≥2% of patients who received intravenous nivolumab were pneumonia, esophageal fistula, interstitial lung disease and pyrexia. The following fatal adverse reactions occurred in patients who received intravenous nivolumab: interstitial lung disease or pneumonitis (1.4%), pneumonia (1.0%), septic shock (0.5%), esophageal fistula (0.5%), gastrointestinal hemorrhage (0.5%), pulmonary embolism (0.5%), and sudden death (0.5%).

Intravenous nivolumab was discontinued in 13% of patients and was delayed in 27% of patients for an adverse reaction.

Tables 41 and 42 summarize the adverse reactions and laboratory abnormalities, respectively, in ATTRACTION-3.

Gastric Cancer, Gastroesophageal Junction Cancer, And Esophageal Adenocarcinoma

CHECKMATE-649

The safety of intravenous nivolumab in combination with chemotherapy was evaluated in CHECKMATE-649, a randomized, multicenter, open-label trial in patients with previously untreated advanced or metastatic gastric cancer, gastroesophageal junction cancer, and esophageal adenocarcinoma [see Clinical Studies]. The trial excluded patients who were known human epidermal growth factor receptor 2 (HER2) positive or had untreated central nervous system (CNS) metastases. Patients were randomized to receive intravenous nivolumab in combination with chemotherapy or chemotherapy. Patients received one of the following treatments:

• intravenous nivolumab 240 mg in combination with mFOLFOX6 (fluorouracil, leucovorin and oxaliplatin) every 2 weeks or mFOLFOX6 every 2 weeks.
• intravenous nivolumab 360 mg in combination with CapeOX (capecitabine and oxaliplatin) every 3 weeks or CapeOX every 3 weeks.

Patients were treated with intravenous nivolumab in combination with chemotherapy or chemotherapy until disease progression, unacceptable toxicity, or up to 2 years. The median duration of exposure was 6.8 months (range: 0 to 33.5 months) in intravenous nivolumab and chemotherapy-treated patients. Among patients who received intravenous nivolumab and chemotherapy, 54% were exposed for >6 months and 28% were exposed for >1 year.

Fatal adverse reactions occurred in 16 (2.0%) patients who were treated with intravenous nivolumab in combination with chemotherapy; these included pneumonitis (4 patients), febrile neutropenia (2 patients), stroke (2 patients), gastrointestinal toxicity, intestinal mucositis, septic shock, pneumonia, infection, gastrointestinal bleeding, mesenteric vessel thrombosis, and disseminated intravascular coagulation. Serious adverse reactions occurred in 52% of patients treated with intravenous nivolumab in combination with chemotherapy. Intravenous nivolumab and/or chemotherapy were discontinued in 44% of patients and at least one dose was withheld in 76% of patients due to an adverse reaction.

The most frequent serious adverse reactions reported in ≥2% of patients treated with intravenous nivolumab in combination with chemotherapy were vomiting (3.7%), pneumonia (3.6%), anemia (3.6%), pyrexia (2.8%), diarrhea (2.7%), febrile neutropenia (2.6%), and pneumonitis (2.4%). The most common adverse reactions reported in ≥20% of patients treated with intravenous nivolumab in combination with chemotherapy were peripheral neuropathy, nausea, fatigue, diarrhea, vomiting, decreased appetite, abdominal pain, constipation, and musculoskeletal pain.

Precautions for Opdivo Qvantig

Severe And Fatal Immune-Mediated Adverse Reactions

OPDIVO QVANTIG is a combination of a monoclonal antibody that belongs to a class of drugs that bind to either the programmed death-receptor 1 (PD-1) or the PD-ligand 1 (PD-L1), blocking the PD-1/PD-L1 pathway, thereby removing inhibition of the immune response, potentially breaking peripheral tolerance, and inducing immunemediated adverse reactions, and an endoglycosidase used to increase the dispersion and absorption of co-administered drugs when administered subcutaneously. Important immune-mediated adverse reactions listed under Warnings and Precautions may not include all possible severe and fatal immune-mediated reactions.

Immune-mediated adverse reactions, which may be severe or fatal, can occur in any organ system or tissue. Immune-mediated adverse reactions can occur at any time after starting treatment with a PD-1/PD-L1 blocking antibody. While immune-mediated adverse reactions usually manifest during treatment with PD-1/PD-L1 blocking antibodies, immune-mediated adverse reactions can also manifest after discontinuation of PD-1/PD-L1 blocking antibodies.

Early identification and management of immune-mediated adverse reactions are essential to ensure safe use of PD-1/PD-L1 blocking antibodies. Monitor patients closely for symptoms and signs that may be clinical manifestations of underlying immunemediated adverse reactions. Evaluate liver enzymes, creatinine, and thyroid function at baseline and periodically during treatment. In cases of suspected immune-mediated adverse reactions, initiate appropriate workup to exclude alternative etiologies, including infection. Institute medical management promptly, including specialty consultation as appropriate.

Withhold or permanently discontinue OPDIVO QVANTIG depending on severity [see DOSAGE AND ADMINISTRATION]. In general, if OPDIVO QVANTIG requires interruption or discontinuation, administer systemic corticosteroid therapy (1 to 2 mg/kg/day prednisone or equivalent) until improvement to Grade 1 or less. Upon improvement to Grade 1 or less, initiate corticosteroid taper and continue to taper over at least 1 month. Consider administration of other systemic immunosuppressants in patients whose immunemediated adverse reactions are not controlled with corticosteroid therapy.

Toxicity management guidelines for adverse reactions that do not necessarily require systemic steroids (e.g., endocrinopathies and dermatologic reactions) are discussed below.

Immune-Mediated Pneumonitis

OPDIVO QVANTIG can cause immune-mediated pneumonitis, which is defined as requiring use of steroids and no clear alternate etiology. In patients treated with other PD-1/PD-L1 blocking antibodies, the incidence of pneumonitis is higher in patients who have received prior thoracic radiation.

Immune-mediated pneumonitis occurred in 2.8% (7/247) of patients receiving OPDIVO QVANTIG, including Grade 3 (0.8%) and Grade 2 (2.0%) adverse reactions. Pneumonitis led to permanent discontinuation of OPDIVO QVANTIG in 1.6% and withholding of OPDIVO QVANTIG in 1.6% of patients.

Systemic corticosteroids were required in 100% (7/7) of patients with pneumonitis. Pneumonitis resolved in 27% of the 7 patients. Of the 4 patients in whom OPDIVO QVANTIG was withheld for pneumonitis, 2 reinitiated OPDIVO QVANTIG after symptom improvement; of these, 1 (50%) had recurrence of pneumonitis.

Immune-Mediated Colitis

OPDIVO QVANTIG can cause immune-mediated colitis, defined as requiring use of corticosteroids and no clear alternate etiology. A common symptom included in the definition of colitis was diarrhea. Cytomegalovirus (CMV) infection/reactivation has been reported in patients with corticosteroid-refractory immune-mediated colitis. In cases of corticosteroid-refractory colitis, consider repeating infectious workup to exclude alternative etiologies.

Immune-mediated colitis occurred in 2.8% (7/247) of patients receiving OPDIVO QVANTIG, including Grade 3 (0.4%) and Grade 2 (2.4%) adverse reactions. Colitis led to withholding of OPDIVO QVANTIG in 2.0% of patients.

Systemic corticosteroids were required in 100% (7/7) of patients with colitis. Colitis resolved in 71% of the 7 patients. Of the 5 patients in whom OPDIVO QVANTIG was withheld for colitis, 3 reinitiated OPDIVO QVANTIG after symptom improvement; of these, 2 (67%) had recurrence of colitis.

Immune-Mediated Hepatitis And Hepatotoxicity

OPDIVO QVANTIG can cause immune-mediated hepatitis, defined as requiring the use of corticosteroids and no clear alternate etiology. Immune-mediated hepatitis occurred in 2.4% (6/247) of patients receiving OPDIVO QVANTIG, including Grade 3 (1.6%), and Grade 2 (0.8%) adverse reactions. Hepatitis led to permanent discontinuation of OPDIVO QVANTIG in 0.8% and withholding of OPDIVO QVANTIG in 1.6% of patients.

Systemic corticosteroids were required in 100% (6/6) of patients with hepatitis. Hepatitis resolved in 67% of the 6 patients. Of the 2 patients in whom OPDIVO QVANTIG was withheld for hepatitis, 2 reinitiated OPDIVO QVANTIG after symptom improvement; of these, 1 (50%) had recurrence of hepatitis.

Intravenous Nivolumab With Cabozantinib

Nivolumab in combination with cabozantinib can cause hepatic toxicity with higher frequencies of Grade 3 and 4 ALT and AST elevations compared to nivolumab alone. Monitor liver enzymes before initiation of and periodically throughout treatment. Consider more frequent monitoring of liver enzymes as compared to when the drugs are administered as single agents. For elevated liver enzymes, interrupt nivolumab and cabozantinib and consider administering corticosteroids [see DOSAGE AND ADMINISTRATION].

With the combination of intravenous nivolumab and cabozantinib, Grades 3 and 4 increased ALT or AST were seen in 11% (35/320) of patients. ALT or AST >3 times ULN (Grade ≥2) was reported in 83 patients, of whom 23 (28%) received systemic corticosteroids; ALT or AST resolved to Grades 0-1 in 74 (89%). Among the 44 patients with Grade ≥2 increased ALT or AST who were rechallenged with either intravenous nivolumab (n=11) or cabozantinib (n=9) administered as a single agent or with both (n=24), recurrence of Grade ≥2 increased ALT or AST was observed in 2 patients receiving intravenous nivolumab, 2 patients receiving cabozantinib, and 7 patients receiving both intravenous nivolumab and cabozantinib.

Immune-Mediated Endocrinopathies

Adrenal Insufficiency

OPDIVO QVANTIG can cause primary or secondary adrenal insufficiency. For Grade 2 or higher adrenal insufficiency, initiate symptomatic treatment, including hormone replacement as clinically indicated. Withhold OPDIVO QVANTIG depending on severity [see DOSAGE AND ADMINISTRATION].

Adrenal insufficiency occurred in 2% (5/247) of patients receiving OPDIVO QVANTIG, including Grade 3 (0.8%) and Grade 2 (1.2%) adverse reactions. Adrenal insufficiency led to permanent discontinuation of OPDIVO QVANTIG in 0.4% of patients and withholding of OPDIVO QVANTIG in 0.4% of patients.

Systemic corticosteroids were required in 100% (5/5) of patients with adrenal insufficiency. Adrenal insufficiency resolved in 20% of the 5 patients.

Intravenous Nivolumab With Cabozantinib

Adrenal insufficiency occurred in 4.7% (15/320) of patients with RCC who received intravenous nivolumab with cabozantinib, including Grade 3 (2.2%) and Grade 2 (1.9%) adverse reactions. Adrenal insufficiency led to permanent discontinuation of intravenous nivolumab and cabozantinib in 0.9% and withholding of intravenous nivolumab and cabozantinib in 2.8% of patients with RCC.

Approximately 80% (12/15) of patients with adrenal insufficiency received hormone replacement therapy, including systemic corticosteroids. Adrenal insufficiency resolved in 27% (n=4) of the 15 patients. Of the 9 patients in whom intravenous nivolumab with cabozantinib was withheld for adrenal insufficiency, 6 reinstated treatment after symptom improvement; of these, all (n=6) received hormone replacement therapy and 2 had recurrence of adrenal insufficiency.

Hypophysitis

OPDIVO QVANTIG can cause immune-mediated hypophysitis. Hypophysitis can present with acute symptoms associated with mass effect such as headache, photophobia, or visual field defects. Hypophysitis can cause hypopituitarism. Initiate hormone replacement as clinically indicated. Withhold or permanently discontinue OPDIVO QVANTIG depending on severity [see DOSAGE AND ADMINISTRATION].

Intravenous Nivolumab

Hypophysitis occurred in 0.6% (12/1994) of patients treated with single agent intravenous nivolumab, including Grade 3 (0.2%) and Grade 2 (0.3%). Hypophysitis led to permanent discontinuation of intravenous nivolumab in 0.2% of patients. Approximately 67% (8/12) of patients with hypophysitis received hormone replacement therapy, including systemic corticosteroids. Hypophysitis resolved in 42% of the 12 patients.  Of the 3 patients in whom intravenous nivolumab was withheld for hypophysitis, 2 reinitiated intravenous nivolumab after symptom improvement; of these, none had recurrence of hypophysitis.

Thyroid Disorders

OPDIVO QVANTIG can cause immune-mediated thyroid disorders. Thyroiditis can present with or without endocrinopathy. Hypothyroidism can follow hyperthyroidism. Initiate hormone replacement or medical management as clinically indicated. Withhold or permanently discontinue OPDIVO QVANTIG depending on severity [see DOSAGE AND ADMINISTRATION].

Thyroiditis

Thyroiditis occurred in 0.4% (1/247) of patients receiving OPDIVO QVANTIG, including a Grade 1 (0.4%) adverse reaction.

Systemic corticosteroids were not required in the patient with thyroiditis. Thyroiditis did not resolve in this patient.

Hyperthyroidism

Hyperthyroidism occurred in 0.8% (2/247) of patients receiving OPDIVO QVANTIG, including Grade 2 (0.4%) adverse reactions.

Systemic corticosteroids were not required in patients with hyperthyroidism. Hyperthyroidism resolved in 50% of the 2 patients.

Hypothyroidism

Hypothyroidism occurred in 9% (23/247) of patients receiving OPDIVO QVANTIG, including Grade 2 (5.7%) adverse reactions. Hypothyroidism led to withholding of OPDIVO QVANTIG in 0.8% of patients.

Systemic corticosteroids were not required in patients with hypothyroidism. Hypothyroidism resolved in 4.3% of the 23 patients. Of the 1 patient in whom OPDIVO QVANTIG was withheld for hypothyroidism, OPDIVO QVANTIG was not reinitiated after symptom improvement.

Type 1 Diabetes Mellitus, Which Can Present With Diabetic Ketoacidosis

Monitor patients for hyperglycemia or other signs and symptoms of diabetes. Initiate treatment with insulin as clinically indicated. Withhold OPDIVO QVANTIG depending on severity [see DOSAGE AND ADMINISTRATION].

Grade 3 diabetes occurred in 0.4% (1/247) of patients receiving OPDIVO QVANTIG.

No patients with diabetes required systemic corticosteroids. Diabetes did not resolve in this patient.

Immune-Mediated Nephritis With Renal Dysfunction

OPDIVO QVANTIG can cause immune-mediated nephritis, which is defined as requiring use of steroids and no clear alternate etiology.

Grade 2 immune-mediated nephritis and renal dysfunction occurred in 1.2% (3/247) of patients receiving OPDIVO QVANTIG. Immune-mediated nephritis and renal dysfunction led to withholding of OPDIVO QVANTIG in 1.2% of patients.

Systemic corticosteroids were required in 100% (3/3) of patients with nephritis and renal dysfunction. Nephritis and renal dysfunction resolved in 100% of the 3 patients. Of the 3 patients in whom OPDIVO QVANTIG was withheld for nephritis or renal dysfunction, 1 reinitiated OPDIVO QVANTIG after symptom improvement without recurrence of nephritis or renal dysfunction.

Immune-Mediated Dermatologic Adverse Reactions

OPDIVO QVANTIG can cause immune-mediated rash or dermatitis, defined as requiring the use of steroids and no clear alternate etiology. Exfoliative dermatitis, including Stevens-Johnson Syndrome, toxic epidermal necrolysis (TEN), and DRESS (Drug Rash with Eosinophilia and Systemic Symptoms), has occurred with PD-1/PD-L1 blocking antibodies. Topical emollients and/or topical corticosteroids may be adequate to treat mild to moderate non-exfoliative rashes. Withhold or permanently discontinue OPDIVO QVANTIG depending on severity [see DOSAGE AND ADMINISTRATION].

Immune-mediated rash occurred in 7% (17/247) of patients, including Grade 3 (0.8%) and Grade 2 (2.8%) adverse reactions. Immune-mediated rash led to withholding of OPDIVO QVANTIG in 1.2% of patients.

Systemic corticosteroids were required in 47% (8/17) of patients with immune-mediated rash. Rash resolved in 77% of the 17 patients. Of the 3 patients in whom OPDIVO QVANTIG was withheld for immune-mediated rash, all reinitiated OPDIVO QVANTIG after symptom improvement; of these, all (100%) had recurrence of immune-mediated rash.

Other Immune-Mediated Adverse Reactions

The following clinically significant immune-mediated adverse reactions occurred at an incidence of <1% (unless otherwise noted) in patients who received OPDIVO QVANTIG or intravenous nivolumab as a single agent or in combination with chemotherapy or immunotherapy, or were reported with the use of other PD-1/PD-L1 blocking antibodies.  Severe or fatal cases have been reported for some of these adverse reactions.

Cardiac/Vascular: Myocarditis, pericarditis, vasculitis

Nervous System: Meningitis, encephalitis, myelitis and demyelination, myasthenic syndrome/myasthenia gravis (including exacerbation), Guillain-Barre syndrome, nerve paresis, autoimmune neuropathy

Ocular: Uveitis, iritis, and other ocular inflammatory toxicities can occur. Some cases can be associated with retinal detachment. Various grades of visual impairment, including blindness, can occur. If uveitis occurs in combination with other immune-mediated adverse reactions, consider a Vogt-Koyanagi-Harada-like syndrome, as this may require treatment with systemic steroids to reduce the risk of permanent vision loss

Gastrointestinal: Pancreatitis to include increases in serum amylase and lipase levels, gastritis, duodenitis

Musculoskeletal and Connective Tissue: Myositis/polymyositis, rhabdomyolysis, and associated sequelae including renal failure, arthritis, polymyalgia rheumatic

Endocrine: Hypoparathyroidism

Other (Hematologic/Immune): Hemolytic anemia, aplastic anemia, hemophagocytic lymphohistiocytosis, systemic inflammatory response syndrome, histiocytic necrotizing lymphadenitis (Kikuchi lymphadenitis), sarcoidosis, immune thrombocytopenic purpura, solid organ transplant rejection, other transplant (including corneal graft) rejection.

Complications Of Allogeneic Hematopoietic Stem Cell Transplantation

Fatal and other serious complications can occur in patients who receive allogeneic hematopoietic stem cell transplantation (HSCT) before or after being treated with a PD-1 receptor blocking antibody. Transplant-related complications include hyperacute graftversus- host-disease (GVHD), acute GVHD, chronic GVHD, hepatic veno-occlusive disease (VOD) after reduced intensity conditioning, and steroid-requiring febrile syndrome (without an identified infectious cause) [see ADVERSE REACTIONS]. These complications may occur despite intervening therapy between PD-1 blockade and allogeneic HSCT.

Follow patients closely for evidence of transplant-related complications and intervene promptly. Consider the benefit versus risks of treatment with a PD-1 receptor blocking antibody prior to or after an allogeneic HSCT.

Embryo-Fetal Toxicity

Based on its mechanism of action and data from animal studies, OPDIVO QVANTIG can cause fetal harm when administered to a pregnant woman. In animal reproduction studies, administration of nivolumab to cynomolgus monkeys from the onset of organogenesis through delivery resulted in increased abortion and premature infant death. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with OPDIVO QVANTIG and for 5 months after the last dose [see Use In Specific Populations].

Increased Mortality In Patients With Multiple Myeloma When Nivolumab Is Added To A Thalidomide Analogue And Dexamethasone

In randomized clinical trials in patients with multiple myeloma, the addition of a PD-1 blocking antibody, including intravenous nivolumab, to a thalidomide analogue plus dexamethasone, a use for which no PD-1 or PD-L1 blocking antibody is indicated, resulted in increased mortality. Treatment of patients with multiple myeloma with a PD-1 or PD-L1 blocking antibody in combination with a thalidomide analogue plus dexamethasone is not recommended outside of controlled clinical trials.

Patient Counseling Information

Advise the patient to read the FDA-approved patient labeling (Medication Guide).

Immune-Mediated Adverse Reactions

Inform patients of the risk of immune-mediated adverse reactions that may require corticosteroid treatment and withholding or discontinuation of OPDIVO QVANTIG, including:

• Pneumonitis: Advise patients to contact their healthcare provider immediately for any new or worsening cough, chest pain, or shortness of breath [see WARNINGS AND PRECAUTIONS].
• Colitis: Advise patients to contact their healthcare provider immediately for diarrhea or severe abdominal pain [see WARNINGS AND PRECAUTIONS].

  • Advise patients that immune-mediated adverse reactions can occur and may involve any organ system, and to contact their healthcare provider immediately for any new or worsening signs or symptoms [see WARNINGS AND PRECAUTIONS].
  • Advise patients of the risk of solid organ transplant rejection and other transplant (including corneal graft) rejection. Advise patients to contact their healthcare provider immediately for signs or symptoms of organ transplant rejection and other transplant (including corneal graft) rejection [see WARNINGS AND PRECAUTIONS].

Complications Of Allogeneic HSCT

• Advise patients of potential risk of post-transplant complications [see WARNINGS AND PRECAUTIONS].

Embryo-Fetal Toxicity

• Advise females of reproductive potential of the potential risk to a fetus and to inform their healthcare provider of a known or suspected pregnancy [see WARNINGS AND PRECAUTIONS and Use In Specific Populations].
• Advise females of reproductive potential to use effective contraception during treatment with OPDIVO QVANTIG and for 5 months following the last dose [see Use In Specific Populations].

Lactation

• Advise women not to breastfeed during treatment with OPDIVO QVANTIG and for 5 months after the last dose [see Use In Specific Populations].

Nonclinical Toxicology

Carcinogenesis, Mutagenesis, Impairment Of Fertility

No studies have been performed to assess the potential of nivolumab for carcinogenicity or genotoxicity. Fertility studies have not been performed with nivolumab. In 1-month and 3-month repeat-dose toxicology studies in monkeys, there were no notable effects in the male and female reproductive organs; however, most animals in these studies were not sexually mature.

Hyaluronidases are found in most tissues of the body. Long-term animal studies have not been performed to assess the carcinogenic or mutagenic potential of hyaluronidase. In addition, when subcutaneous hyaluronidase (recombinant human) was administered to cynomolgus monkeys for 39 weeks at dose levels up to 220,000 U/kg, which is at least 600 times higher than the human dose (U/kg basis), of 10,000 U once every 2 weeks, 15,000 U once every 3 weeks, or 20,000 U once every 4 weeks, no evidence of toxicity to the male or female reproductive system was found through periodic monitoring of in-life parameters, e.g., semen analyses, hormone levels, menstrual cycles, and also from gross pathology, histopathology and organ weight data.

Use In Specific Populations

Pregnancy

Risk Summary

Based on data from animal studies and its mechanism of action [see CLINICAL PHARMACOLOGY], OPDIVO QVANTIG can cause fetal harm when administered to a pregnant woman. In animal reproduction studies, administration of nivolumab to cynomolgus monkeys from the onset of organogenesis through delivery resulted in increased abortion and premature infant death (see Data). Human IgG4 is known to cross the placental barrier and nivolumab is an immunoglobulin G4 (IgG4); therefore, nivolumab has the potential to be transmitted from the mother to the developing fetus. The effects of OPDIVO QVANTIG are likely to be greater during the second and third trimesters of pregnancy. There are no available data on OPDIVO QVANTIG use in pregnant women to evaluate a drug-associated risk. Advise pregnant women of the potential risk to a fetus.

The background risk in the U.S. general population of major birth defects is 2% to 4% and of miscarriage is 15% to 20% of clinically recognized pregnancies.

Data

Animal Data

OPDIVO QVANTIG for subcutaneous injection contains nivolumab and hyaluronidase [see DESCRIPTION].

Nivolumab

A central function of the PD-1/PD-L1 pathway is to preserve pregnancy by maintaining maternal immune tolerance to the fetus. Blockade of PD-L1 signaling has been shown in murine models of pregnancy to disrupt tolerance to the fetus and to increase fetal loss. The effects of nivolumab on prenatal and postnatal development were evaluated in monkeys that received nivolumab intravenously twice weekly from the onset of organogenesis through delivery, at exposure levels of between 4 and 15 times higher than those observed at the clinical dose of 600 mg once every 2 weeks, 900 mg once every 3 weeks, or 1,200 mg once every 4 weeks (based on AUC). Nivolumab administration resulted in a non-dose-related increase in spontaneous abortion and increased neonatal death. Based on its mechanism of action, fetal exposure to nivolumab may increase the risk of developing immune-mediated disorders or altering the normal immune response, and immune-mediated disorders have been reported in PD-1 knockout mice. In surviving infants (18 of 32 compared to 11 of 16 vehicle-exposed infants) of cynomolgus monkeys treated with nivolumab, there were no apparent malformations and no effects on neurobehavioral, immunological, or clinical pathology parameters throughout the 6-month postnatal period.

Hyaluronidase

In an embryo-fetal development study, mice were dosed daily by subcutaneous injection during the period of organogenesis with hyaluronidase (recombinant human) at dose levels up to 2,200,000 U/kg, which is at least 6,600 times higher than the human dose of 10,000 U once every 2 weeks, 15,000 U once every 3 weeks, or 20,000 U once every 4 weeks (U/kg basis), when administered with nivolumab. The study found no evidence of teratogenicity. Reduced fetal weight and increased numbers of fetal resorptions were observed, with no effects found at a daily dose of 360,000 U/kg, which is at least 1,080 times higher than the human dose of 10,000 U once every 2 weeks, 15,000 U once every 3 weeks, or 20,000 U once every 4 weeks (U/kg basis), when administered with nivolumab.

Lactation

Risk Summary

There are no data on the presence of nivolumab or hyaluronidase in human milk, the effects on the breastfed child, or the effects on milk production. Because of the potential for serious adverse reactions in the breastfed child, advise women not to breastfeed during treatment and for 5 months after the last dose of OPDIVO QVANTIG.

Females And Males Of Reproductive Potential

Pregnancy Testing

Verify the pregnancy status of females of reproductive potential prior to initiating OPDIVO QVANTIG [see Use In Specific Populations].

Contraception

OPDIVO QVANTIG can cause fetal harm when administered to a pregnant woman [see Use In Specific Populations]. Advise females of reproductive potential to use effective contraception during treatment with OPDIVO QVANTIG and for 5 months following the last dose.

Pediatric Use

The safety and effectiveness of OPDIVO QVANTIG have not been established in pediatric patients.

Geriatric Use

Monotherapy

Of the 248 patients who were randomized to monotherapy OPDIVO QVANTIG in clinical studies, 48% were 65 years and over and 14% were 75 years and over. No overall differences in safety or effectiveness were observed between elderly patients and younger patients.

Single Agent Intravenous Nivolumab

Of 3569 patients with melanoma, NSCLC, renal cell carcinoma, urothelial carcinoma, ESCC, and esophageal or gastroesophageal junction cancer who were randomized to single agent intravenous nivolumab in clinical studies, 41% were 65 years and over and 10% were 75 years and over. No overall differences in safety or effectiveness were observed between elderly patients and younger patients [see Clinical Studies].

Clinical studies in patients with recurrent head and neck SCC, or dMMR or MSI-H metastatic CRC (mCRC) who were treated with single agent intravenous nivolumab did not include sufficient numbers of patients aged 65 years and over to determine whether they respond differently from younger patients [see Clinical Studies].

Intravenous Nivolumab In Combination With Platinum-Containing Chemotherapy

Of the 179 patients with NSCLC who were randomized to intravenous nivolumab in combination with platinum-doublet chemotherapy, 48% were 65 years old or older and 6% were 75 years old or older. No overall differences in safety or effectiveness were reported between patients older and younger than 65 years [see Clinical Studies].

Of the 229 patients with NSCLC who were randomized to intravenous nivolumab 360 mg in combination with platinum-doublet chemotherapy every 3 weeks for up to 4 cycles, followed by intravenous nivolumab 480 mg every 4 weeks, 56% were 65 years old or older and 7% were 75 years old or older. No overall differences in safety or effectiveness were reported between patients older and younger than 65 years.

Of the 1,110 patients with ESCC, GC, GEJC, or EAC who were randomized to intravenous nivolumab in combination with fluoropyrimidine- and platinum-containing chemotherapy, 42% were 65 years or older and 10% were 75 years or older. No overall difference in safety was reported between elderly patients and younger patients [see Clinical Studies].

Of the 304 patients with UC who were treated with intravenous nivolumab in combination with gemcitabine and platinum-doublet chemotherapy, 40% were 65 years or older and 11% were 75 years or older. No overall differences in safety or effectiveness were observed between patients 65 years of age and over and younger patients. Clinical studies of intravenous nivolumab with platinum-doublet chemotherapy did not include sufficient numbers of patients aged 75 years and over to determine whether safety and effectiveness differs compared to younger patients. [see Clinical Studies].

In Combination With Cabozantinib

Of the 320 patients with renal cell carcinoma who were treated with intravenous nivolumab in combination with cabozantinib, 41% were 65 years or older and 9% were 75 years or older. No overall difference in safety was reported between elderly patients and younger patients [see Clinical Studies].

Clinical Pharmacology for Opdivo Qvantig

Mechanism Of Action

Binding of the PD-1 ligands, PD-L1 and PD-L2, to the PD-1 receptor found on T cells, inhibits T-cell proliferation and cytokine production. Upregulation of PD-1 ligands occurs in some tumors and signaling through this pathway can contribute to inhibition of active T-cell immune surveillance of tumors. Nivolumab is a human immunoglobulin G4 (IgG4) monoclonal antibody that binds to the PD-1 receptor and blocks its interaction with PD-L1 and PD-L2, releasing PD-1 pathway-mediated inhibition of the immune response, including the anti-tumor immune response. In syngeneic mouse tumor models, blocking PD-1 activity resulted in decreased tumor growth.

Hyaluronan is a polysaccharide found in the extracellular matrix of the subcutaneous tissue. It is depolymerized by the naturally occurring enzyme hyaluronidase. Unlike the stable structural components of the interstitial matrix, hyaluronan has a half-life of approximately 0.5 days. Hyaluronidase increases permeability of the subcutaneous tissue by temporarily depolymerizing hyaluronan. In the doses administered, hyaluronidase in OPDIVO QVANTIG acts transiently and locally. The effects of hyaluronidase are reversible and permeability of the subcutaneous tissue is restored within 24 to 48 hours.

Pharmacodynamics

Exposure-Response Relationship

The exposure-response relationship and time course of pharmacodynamics of OPDIVO QVANTIG have not been fully characterized.

Pharmacokinetics

When comparing nivolumab exposures following OPDIVO QVANTIG to those of intravenous nivolumab in CHECKMATE-67T [see Clinical Studies], the geometric mean ratios (GMRs) (90% CI) for time-averaged concentration (C avg) over 28 days and at steady state were 2.10 (2.00, 2.20) and 1.98 (1.87, 2.11), respectively, and for minimum concentration (C min) at 28 days and at steady state were 1.60 (1.49, 1.72) and 1.77 (1.63, 1.93), respectively.

Steady state was achieved by 16 weeks. The systemic accumulation ratio was 2.3.

Absorption

The geometric mean bioavailability (CV%) of nivolumab is 74% (14%). Peak concentrations occurred by around 6 days.

Distribution

The geometric mean (CV%) volume of distribution at steady state is 6.8 L (27%).

Elimination

Nivolumab clearance decreases over time, with a mean maximal reduction (CV%) from baseline values of 24.5% (47.6%), resulting in a geometric mean steady-state clearance (CV%) of 8.2 mL/h (53.9%) in patients with metastatic tumors; this decrease in clearance is not considered clinically relevant. Nivolumab clearance does not decrease over time in patients with completely resected melanoma, as the geometric mean population clearance is 24% lower in this patient population compared with patients with metastatic melanoma at steady state.

The geometric mean (CV%) elimination half-life is 25 days (78%).

Specific Populations

Body weight (35 to 153 kg), sex, eGFR (24 to 124 mL/min/1.73 m²), and performance status have no clinically significant effects on the clearance of nivolumab.

Immunogenicity

The observed incidence of anti-drug antibodies is highly dependent on the sensitivity and specificity of the assay. Differences in assay methods preclude meaningful comparisons of the incidence of anti-drug antibodies in the studies described below with the incidence of anti-drug antibodies in other studies, including those of OPDIVO QVANTIG or of other nivolumab products or hyaluronidase products.

During the 2-year treatment period in CHECKMATE-67T [see Clinical Studies], 23% (46/202) of patients who received OPDIVO QVANTIG developed anti-nivolumab antibodies (ADA) and 4.3% (2/46) had neutralizing antibodies against nivolumab (NAb). The corresponding incidence of ADA was 7% (15/215) and NAb was 0% (0/15) for intravenous nivolumab in the same study. The incidence of anti-hyaluronidase antibodies in CHECKMATE-67T was 8.8% (19/215); 5 (26%) of these 19 patients developed NAb.

Nivolumab clearance increased by approximately 26% in patients who received OPDIVO QVANTIG and tested positive for ADA compared to patients who tested negative for ADA; this change in clearance is not considered clinically significant. Local injection-site reactions were reported in 15% (7/46) of patients who developed ADA to nivolumab and 7% (10/155) of patients who did not develop ADA to nivolumab; however, all events were Grade 1 or 2 and resolved. Because of low occurrence of anti-nivolumab or anti-hyaluronidase antibodies, the effect of ADA on the effectiveness of OPDIVO QVANTIG is unknown.

Animal Toxicology And/Or Pharmacology

In animal models, inhibition of PD-1 signaling increased the severity of some infections and enhanced inflammatory responses. Mycobacterium tuberculosis –infected PD-1 knockout mice exhibit markedly decreased survival compared with wild-type controls, which correlated with increased bacterial proliferation and inflammatory responses in these animals. PD-1 blockade using a primate anti–PD-1 antibody was also shown to exacerbate M. tuberculosis infection in rhesus macaques. PD-1 knockout mice have also shown decreased survival following infection with lymphocytic choriomeningitis virus.

Clinical Studies

Advanced Renal Cell Carcinoma

Previously Treated Renal Cell Carcinoma – OPDIVO QVANTIG

The efficacy of OPDIVO QVANTIG was evaluated in CHECKMATE-67T (NCT04810078), a multicenter, randomized, open-label study in patients with advanced or metastatic clear cell renal cell carcinoma. Patients 18 years of age or older with histologically confirmed advanced or metastatic renal cell carcinoma with a clear cell component, including those with sarcomatoid features, and who received no more than 2 prior systemic treatment regimens were randomized to receive OPDIVO QVANTIG (containing 1,200 mg of nivolumab and 20,000 units of hyaluronidase) every 4 weeks subcutaneously, or nivolumab 3 mg/kg every 2 weeks intravenously. Patients with untreated, symptomatic central nervous system (CNS) metastases; leptomeningeal metastases; concurrent malignancies requiring treatment or history of prior malignancy within the previous 2 years; active, known, or suspected autoimmune disease; or who received prior treatment with a checkpoint inhibitor were excluded from the study. Patients with asymptomatic, stable CNS metastases that did not require immediate treatment were eligible if there was no evidence of progression within 28 days prior to the first dose of study drug administration. Stratification factors for randomization were weight (<80 kg vs ≥80 kg) and International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) risk classification (favorable vs intermediate, vs poor risk). The primary objective was to assess the nivolumab exposure of subcutaneous administration of OPDIVO QVANTIG as compared to the intravenous administration of nivolumab. The secondary objective of the study was to evaluate overall response rate (ORR) by blinded independent central review (BICR).

A total of 495 patients were randomized to receive either OPDIVO QVANTIG (n=248) or intravenous nivolumab (n=247). The median age was 65 years (range: 20 to 93), with 51% ≥65 years of age and 14% ≥75 years of age; 68% male; 85% White, 12.5% not reported, 1% American Indian or Alaska Native, 0.8% Asian, and 0.4% Black; 36% Hispanic or Latino, 33% not Hispanic or Latino, and 31% not reported. Fifty-seven percent of patients weighed <80 kg and 43% weighed ≥80 kg. Baseline Karnofsky performance status was 70 (7%), 80 (20%), 90 (34%), or 100 (39%). Patient distribution by IMDC risk categories was 21% favorable, 62% intermediate, and 17% poor.

When comparing subcutaneous administration of OPDIVO QVANTIG to the intravenous administration of nivolumab, CHECKMATE-67T met the predefined acceptance margin for pharmacokinetic endpoints, with the lower boundary of 90% confidence interval of geometric mean ratios of not less than 0.8 for both serum nivolumab C avg over 28 days and C min at steady state. [see CLINICAL PHARMACOLOGY]. Efficacy results are shown in Table 45.

RCC Trials - Intravenous Nivolumab

The effectiveness of OPDIVO QVANTIG has been established for the following:

• as monotherapy, for advanced renal cell carcinoma (RCC) following treatment with intravenous nivolumab and ipilimumab combination therapy (CHECKMATE-214 study).
• in combination with cabozantinib, for the first-line treatment of adult patients with advanced RCC (CHECKMATE-9ER study).
• as monotherapy, for the treatment of adult patients with advanced RCC who have received prior anti-angiogenic therapy (CHECKMATE-025 study).

Use of OPDIVO QVANTIG for these RCC indications is supported by evidence from adequate and well-controlled studies conducted with intravenous nivolumab, and additional pharmacokinetic and safety data that demonstrated comparable pharmacokinetics and safety profiles between OPDIVO QVANTIG and intravenous nivolumab in the CHECKMATE-67T trial [see ADVERSE REACTIONS, CLINICAL PHARMACOLOGY, and Clinical Studies]. Below is a description of the efficacy results of these adequate and well-controlled studies of intravenous nivolumab in these RCC populations.

First-line Renal Cell Carcinoma

CHECKMATE-214

CHECKMATE-214 (NCT02231749) was a randomized (1:1), open-label trial in patients with previously untreated advanced RCC. Patients were included regardless of their PD-L1 status. CHECKMATE-214 excluded patients with any history of or concurrent brain metastases, active autoimmune disease, or medical conditions requiring systemic immunosuppression. Patients were stratified by International Metastatic RCC Database Consortium (IMDC) prognostic score and region.

Efficacy was evaluated in intermediate/poor risk patients with at least 1 or more of 6 prognostic risk factors as per the IMDC criteria (less than one year from time of initial renal cell carcinoma diagnosis to randomization, Karnofsky performance status <80%, hemoglobin less than the lower limit of normal, corrected calcium of >10 mg/dL, platelet count greater than the upper limit of normal, and absolute neutrophil count greater than the upper limit of normal).

Patients were randomized to nivolumab 3 mg/kg and ipilimumab 1 mg/kg intravenously every 3 weeks for 4 doses followed by nivolumab 3 mg/kg intravenously every two weeks (n=425), or sunitinib 50 mg orally daily for the first 4 weeks of a 6-week cycle (n=422). Treatment continued until disease progression or unacceptable toxicity.

The trial population characteristics were: median age was 61 years (range: 21 to 85) with 38% ≥65 years of age and 8% ≥75 years of age. The majority of patients were male (73%) and White (87%) and 26% and 74% of patients had a baseline KPS of 70% to 80% and 90% to 100%, respectively.

The major efficacy outcome measures were OS, PFS (independent radiographic review committee [IRRC]-assessed) and confirmed ORR (IRRC-assessed) in intermediate/ poor risk patients. In this population, the trial demonstrated statistically significant improvement in OS and ORR for patients randomized to intravenous nivolumab and ipilimumab as compared with sunitinib (Table 46 and Figure 1). OS benefit was observed regardless of PD-L1 expression level. The trial did not demonstrate a statistically significant improvement in PFS. Efficacy results are shown in Table 46 and Figure 1.

Figure 1: Overall Survival (Intermediate/Poor Risk Population) - CHECKMATE-214

CHECKMATE-214 also randomized 249 favorable risk patients as per IMDC criteria to intravenous nivolumab and ipilimumab (n=125) or to sunitinib (n=124). These patients were not evaluated as part of the efficacy analysis population. OS in favorable risk patients receiving intravenous nivolumab and ipilimumab compared to sunitinib has a hazard ratio of 1.45 (95% CI: 0.75, 2.81). The efficacy of intravenous nivolumab and ipilimumab in previously untreated renal cell carcinoma with favorable-risk disease has not been established.

CHECKMATE-9ER

CHECKMATE-9ER (NCT03141177) was a randomized, open-label study of intravenous nivolumab combined with cabozantinib versus sunitinib in patients with previously untreated advanced RCC. CHECKMATE-9ER excluded patients with autoimmune disease or other medical conditions requiring systemic immunosuppression. Patients were stratified by IMDC prognostic score (favorable vs. intermediate vs. poor), PD-L1 tumor expression (≥1% vs. <1% or indeterminate), and region (US/Canada/Western Europe/ Northern Europe vs. Rest of World).

Patients were randomized to nivolumab 240 mg intravenously every 2 weeks and cabozantinib 40 mg orally daily (n=323), or sunitinib 50 mg orally daily for the first 4 weeks of a 6-week cycle (4 weeks on treatment followed by 2 weeks off) (n=328). Treatment continued until disease progression per RECIST v1.1 or unacceptable toxicity. Treatment beyond RECIST-defined disease progression was permitted if the patient was clinically stable and considered to be deriving clinical benefit by the investigator. Tumor assessments were performed at baseline, after randomization at Week 12, then every 6 weeks until Week 60, and then every 12 weeks thereafter.

The trial population characteristics were: median age 61 years (range: 28 to 90) with 38% ≥65 years of age and 10% ≥75 years of age. The majority of patients were male (74%) and White (82%) and 23% and 77% of patients had a baseline KPS of 70% to 80% and 90% to 100%, respectively. Patient distribution by IMDC risk categories was 22% favorable, 58% intermediate, and 20% poor.

The major efficacy outcome measure was PFS (BICR assessed). Additional efficacy outcome measures were OS and ORR (BICR assessed). The trial demonstrated a statistically significant improvement in PFS, OS, and ORR for patients randomized to intravenous nivolumab and cabozantinib compared with sunitinib. Consistent results for PFS were observed across pre-specified subgroups of IMDC risk categories and PD-L1 tumor expression status. An updated OS analysis was conducted when 271 deaths were observed based on the pre-specified number of deaths for the pre-planned final analysis of OS. Efficacy results are shown in Table 47 and Figures 2 and 3.

In an exploratory analysis, the updated analysis of OS in patients with IMDC favorable, intermediate, intermediate/poor, and poor risk demonstrated a HR (95% CI) of 1.03 (0.55, 1.92), 0.74 (0.54, 1.01), 0.65 (0.50, 0.85), and 0.49 (0.31, 0.79), respectively.

Previously Treated Renal Cell Carcinoma

CHECKMATE-025

CHECKMATE-025 (NCT01668784) was a randomized (1:1), open-label trial in patients with advanced RCC who had experienced disease progression during or after one or two prior anti-angiogenic therapy regimens. Patients had to have a Karnofsky Performance Score (KPS) ≥70% and patients were included regardless of their PD-L1 status. The trial excluded patients with any history of or concurrent brain metastases, prior treatment with an mTOR inhibitor, active autoimmune disease, or medical conditions requiring systemic immunosuppression. Patients were stratified by region, Memorial Sloan Kettering Cancer Center (MSKCC) Risk Group and the number of prior anti-angiogenic therapies. Patients were randomized to nivolumab 3 mg/kg by intravenous infusion every 2 weeks (n=410) or everolimus 10 mg orally daily (n=411). The first tumor assessments were conducted 8 weeks after randomization and continued every 8 weeks thereafter for the first year and then every 12 weeks until progression or treatment discontinuation, whichever occurred later. The major efficacy outcome measure was overall survival (OS).

The trial population characteristics were: median age was 62 years (range: 18 to 88) with 40% ≥65 years of age and 9% ≥75 years of age. The majority of patients were male (75%) and White (88%) and 34% and 66% of patients had a baseline KPS of 70% to 80% and 90% to 100%, respectively. The majority of patients (77%) were treated with one prior anti-angiogenic therapy. Patient distribution by MSKCC risk groups was 34% favorable, 47% intermediate, and 19% poor.

The trial demonstrated a statistically significant improvement in OS for patients randomized to intravenous nivolumab as compared with everolimus at the prespecified interim analysis when 398 events were observed (70% of the planned number of events for final analysis). OS benefit was observed regardless of PD-L1 expression level. Efficacy results are shown in Table 48 and Figure 4.

Unresectable Or Metastatic Melanoma

Previously Treated Metastatic Melanoma

The effectiveness of OPDIVO QVANTIG has been established for the treatment of previously treated unresectable or metastatic melanoma. Use of OPDIVO QVANTIG for this indication is supported by evidence from an adequate and well-controlled study conducted with intravenous nivolumab, and additional pharmacokinetic and safety data that demonstrated comparable pharmacokinetics and safety profiles between OPDIVO QVANTIG and intravenous nivolumab [see ADVERSE REACTIONS and CLINICAL PHARMACOLOGY]. Below is a description of the efficacy results of this adequate and well-controlled study of intravenous nivolumab in this melanoma population.

OPDIVO QVANTIG is not indicated for the treatment of pediatric patients.

CHECKMATE-037

CHECKMATE-037 (NCT01721746) was a multicenter, open-label trial that randomized (2:1) patients with unresectable or metastatic melanoma to receive nivolumab 3 mg/kg intravenously every 2 weeks or investigator’s choice of chemotherapy, either singleagent dacarbazine 1000 mg/m² every 3 weeks or the combination of carboplatin AUC 6 intravenously every 3 weeks and paclitaxel 175 mg/m² intravenously every 3 weeks. Patients were required to have progression of disease on or following ipilimumab treatment and, if BRAF V600 mutation positive, a BRAF inhibitor. The trial excluded patients with autoimmune disease, medical conditions requiring systemic immunosuppression, ocular melanoma, active brain metastasis, or a history of Grade 4 ipilimumab-related adverse reactions (except for endocrinopathies) or Grade 3 ipilimumab-related adverse reactions that had not resolved or were inadequately controlled within 12 weeks of the initiating event. Tumor assessments were conducted 9 weeks after randomization then every 6 weeks for the first year, and every 12 weeks thereafter.

Efficacy was evaluated in a single-arm, non-comparative, planned interim analysis of the first 120 patients who received intravenous nivolumab in CHECKMATE-037 and in whom the minimum duration of follow-up was 6 months. The major efficacy outcome measures in this population were confirmed overall response rate (ORR) as measured by blinded independent central review using Response Evaluation Criteria in Solid Tumors (RECIST 1.1) and duration of response.

Among the 120 patients treated with intravenous nivolumab, the median age was 58 years (range: 25 to 88), 65% of patients were male, 98% were White, and the ECOG performance score was 0 (58%) or 1 (42%). Disease characteristics were M1c disease (76%), BRAF V600 mutation positive (22%), elevated LDH (56%), history of brain metastases (18%), and two or more prior systemic therapies for metastatic disease (68%).

The ORR was 32% (95% confidence interval [CI]: 23, 41), consisting of 4 complete responses and 34 partial responses in intravenous nivolumab-treated patients. Of 38 patients with responses, 87% had ongoing responses with durations ranging from 2.6+ to 10+ months, which included 13 patients with ongoing responses of 6 months or longer.

There were responses in patients with and without BRAF V600 mutation-positive melanoma. A total of 405 patients were randomized and the median duration of OS was 15.7 months (95% CI: 12.9, 19.9) in nivolumab-treated patients compared to 14.4 months (95% CI: 11.7, 18.2) (HR 0.95; 95.54% CI: 0.73, 1.24) in patients assigned to investigator’s choice of treatment. Figure 5 summarizes the OS results.

Figure 5: Overall Survival - CHECKMATE-037*

* The primary OS analysis was not adjusted to account for subsequent therapies, with 54 (40.6%) patients in the chemotherapy arm subsequently receiving an anti-PD1 treatment. OS may be confounded by dropout, imbalance of subsequent therapies, and differences in baseline factors.

Previously Untreated Metastatic Melanoma

The effectiveness of OPDIVO QVANTIG has been established for the treatment of previously untreated unresectable or metastatic melanoma. Use of OPDIVO QVANTIG for this indication is supported by evidence from adequate and well-controlled studies conducted with intravenous nivolumab, and additional pharmacokinetic and safety data that demonstrated comparable pharmacokinetics and safety profiles between OPDIVO QVANTIG and intravenous nivolumab [see ADVERSE REACTIONS and CLINICAL PHARMACOLOGY]. Below is a description of the efficacy results of these adequate and well-controlled studies of intravenous nivolumab in this melanoma population.

CHECKMATE-066

CHECKMATE-066 (NCT01721772) was a multicenter, double-blind, randomized (1:1) trial in 418 patients with BRAF V600 wild-type unresectable or metastatic melanoma. Patients were randomized to receive either nivolumab 3 mg/kg by intravenous infusion every 2 weeks or dacarbazine 1000 mg/m² intravenously every 3 weeks until disease progression or unacceptable toxicity. Randomization was stratified by PD-L1 status (≥5% of tumor cell membrane staining by immunohistochemistry vs. <5% or indeterminate result) and M stage (M0/M1a/M1b versus M1c). Key eligibility criteria included histologically confirmed, unresectable or metastatic, cutaneous, mucosal, or acral melanoma; no prior therapy for metastatic disease; completion of prior adjuvant or neoadjuvant therapy at least 6 weeks prior to randomization; ECOG performance status 0 or 1; absence of autoimmune disease; and absence of active brain or leptomeningeal metastases. The trial excluded patients with ocular melanoma. Tumor assessments were conducted 9 weeks after randomization then every 6 weeks for the first year and then every 12 weeks thereafter. The major efficacy outcome measure was overall survival (OS). Additional outcome measures included investigator-assessed progression-free survival (PFS) and ORR per RECIST v1.1.

The trial population characteristics were: median age was 65 years (range: 18 to 87), 59% were male, and 99.5% were White. Disease characteristics were M1c stage disease (61%), cutaneous melanoma (74%), mucosal melanoma (11%), elevated LDH level (37%), PD-L1 ≥5% tumor cell membrane expression (35%), and history of brain metastasis (4%). More patients in the intravenous nivolumab arm had an ECOG performance status of 0 (71% vs. 58%).

CHECKMATE-066 demonstrated a statistically significant improvement in OS for the intravenous nivolumab arm compared with the dacarbazine arm in an interim analysis based on 47% of the total planned events for OS. At the time of analysis, 88% (63/72) of intravenous nivolumab-treated patients had ongoing responses, which included 43 patients with ongoing response of 6 months or longer. Efficacy results are shown in Table 49 and Figure 6.

CHECKMATE-067

CHECKMATE-067 (NCT01844505) was a multicenter, randomized (1:1:1), double-blind trial in 945 patients with previously untreated, unresectable or metastatic melanoma to one of the following arms: intravenous nivolumab and ipilimumab, intravenous nivolumab, or ipilimumab. Patients were required to have completed adjuvant or neoadjuvant treatment at least 6 weeks prior to randomization and have no prior treatment with anti-CTLA-4 antibody and no evidence of active brain metastasis, ocular melanoma, autoimmune disease, or medical conditions requiring systemic immunosuppression.

Patients were randomized to receive:

• Nivolumab 1 mg/kg with ipilimumab 3 mg/kg intravenously every 3 weeks for 4 doses, followed by nivolumab as a single agent at a dose of 3 mg/kg by intravenous infusion every 2 weeks (nivolumab and ipilimumab arm),
• Nivolumab 3 mg/kg by intravenous infusion every 2 weeks (nivolumab arm), or
• Ipilimumab 3 mg/kg intravenously every 3 weeks for 4 doses, followed by placebo every 2 weeks (ipilimumab arm).

Randomization was stratified by PD-L1 expression (≥5% vs. <5% tumor cell membrane expression) as determined by a clinical trial assay, BRAF V600 mutation status, and M stage per the AJCC staging system (M0, M1a, M1b vs. M1c). Tumor assessments were conducted 12 weeks after randomization then every 6 weeks for the first year, and every 12 weeks thereafter. The major efficacy outcome measures were investigatorassessed PFS per RECIST v1.1 and OS. Additional efficacy outcome measures were confirmed ORR and duration of response.

The trial population characteristics were: median age 61 years (range: 18 to 90); 65% male; 97% White; ECOG performance score 0 (73%) or 1 (27%). Disease characteristics were: AJCC Stage IV disease (93%); M1c disease (58%); elevated LDH (36%); history of brain metastases (4%); BRAF V600 mutation-positive melanoma (32%); PD-L1 ≥5% tumor cell membrane expression as determined by the clinical trials assay (46%); and prior adjuvant therapy (22%).

CHECKMATE-067 demonstrated statistically significant improvements in OS and PFS for patients randomized to either intravenous nivolumab-containing arm as compared with the ipilimumab arm. The trial was not designed to assess whether adding ipilimumab to intravenous nivolumab improves PFS or OS compared to intravenous nivolumab as a single agent. Efficacy results are shown in Table 50 and Figure 7.

Figure 7: Overall Survival - CHECKMATE-067

Based on a minimum follow-up of 48 months, the median OS was not reached (95% CI: 38.2, NR) in the intravenous nivolumab and ipilimumab arm. The median OS was 36.9 months (95% CI: 28.3, NR) in the intravenous nivolumab arm and 19.9 months (95% CI: 16.9, 24.6) in the ipilimumab arm.

Based on a minimum follow-up of 28 months, the median PFS was 11.7 months (95% CI: 8.9, 21.9) in the intravenous nivolumab and ipilimumab arm, 6.9 months (95% CI: 4.3, 9.5) in the intravenous nivolumab arm, and 2.9 months (95% CI: 2.8, 3.2) in the ipilimumab arm. Based on a minimum follow-up of 28 months, the proportion of responses lasting ≥24 months was 55% in the intravenous nivolumab and ipilimumab arm, 56% in the intravenous nivolumab arm, and 39% in the ipilimumab arm.

Adjuvant Treatment Of Melanoma

The effectiveness of OPDIVO QVANTIG has been established for the adjuvant treatment of Stage IIB, Stage IIC, Stage III, or Stage IV melanoma. Use of OPDIVO QVANTIG for this indication is supported by evidence from adequate and well-controlled studies conducted with intravenous nivolumab [see ADVERSE REACTIONS and CLINICAL PHARMACOLOGY]. Below is a description of the efficacy results of these adequate and wellcontrolled studies of intravenous nivolumab in these melanoma populations.

OPDIVO QVANTIG is not indicated for the treatment of pediatric patients.

CHECKMATE-76K

CHECKMATE-76K (NCT04099251) was a randomized, double-blind trial in 790 patients with completely resected Stage IIB/C melanoma. Patients were randomized (2:1) to receive nivolumab 480 mg or placebo by intravenous infusion every 4 weeks for up to 1 year or until disease recurrence or unacceptable toxicity. Enrollment required complete resection of the primary melanoma with negative margins and a negative sentinel lymph node within 12 weeks prior to randomization, and ECOG performance status of 0 or 1. The trial excluded patients with ocular/uveal or mucosal melanoma, autoimmune disease, any condition requiring systemic treatment with either corticosteroids (≥10 mg daily prednisone or equivalent) or other immunosuppressive medications, as well as patients with prior therapy for melanoma except surgery. Randomization was stratified by AJCC 8th staging system edition (T3b vs. T4a vs. T4b). The major efficacy outcome measure was recurrence-free survival (RFS) defined as the time between the date of randomization and the date of first recurrence (local, regional, or distant metastasis), new primary melanoma, or death, from any cause, whichever occurred first and as assessed by the investigator. Tumor assessments were conducted every 26 weeks during years 1-3 and every 52 weeks thereafter until year 5.

The trial population characteristics were: median age 62 years (range: 19 to 92), 61% were male, 98% were White, 0.4% Black or African American, 0.1% Asian, and 1.1% race unknown, 2.2% Hispanic or Latino, 58% Not Hispanic or Latino, 40% ethnicity unknown, and 94% had an ECOG performance status of 0. Sixty one percent had stage IIB and 39% had stage IIC melanoma.

CHECKMATE-76K demonstrated a statistically significant improvement in RFS for patients randomized to the intravenous nivolumab arm compared with the placebo arm. Efficacy results are shown in Table 51 and Figure 8.

CHECKMATE-238

CHECKMATE-238 (NCT02388906) was a randomized, double-blind trial in 906 patients with completely resected Stage IIIB/C or Stage IV melanoma. Patients were randomized (1:1) to receive nivolumab 3 mg/kg by intravenous infusion every 2 weeks or ipilimumab 10 mg/kg intravenously every 3 weeks for 4 doses then every 12 weeks beginning at Week 24 for up to 1 year. Enrollment required complete resection of melanoma with margins negative for disease within 12 weeks prior to randomization. The trial excluded patients with a history of ocular/uveal melanoma, autoimmune disease, and any condition requiring systemic treatment with either corticosteroids (≥10 mg daily prednisone or equivalent) or other immunosuppressive medications, as well as patients with prior therapy for melanoma except surgery, adjuvant radiotherapy after neurosurgical resection for lesions of the central nervous system, and prior adjuvant interferon completed ≥6 months prior to randomization. Randomization was stratified by PD-L1 status (positive [based on 5% level] vs. negative/indeterminate) and AJCC stage (Stage IIIB/C vs. Stage IV M1a-M1b vs. Stage IV M1c). The major efficacy outcome measure was recurrence-free survival (RFS) defined as the time between the date of randomization and the date of first recurrence (local, regional, or distant metastasis), new primary melanoma, or death, from any cause, whichever occurs first and as assessed by the investigator. Patients underwent imaging for tumor recurrence every 12 weeks for the first 2 years then every 6 months thereafter.

The trial population characteristics were: median age was 55 years (range: 18 to 86), 58% were male, 95% were White, and 90% had an ECOG performance status of 0. Disease characteristics were AJCC Stage IIIB (34%), Stage IIIC (47%), Stage IV (19%), M1a-b (14%), BRAF V600 mutation positive (42%), BRAF wild-type (45%), elevated LDH (8%), PD-L1 ≥5% tumor cell membrane expression determined by clinical trial assay (34%), macroscopic lymph nodes (48%), and tumor ulceration (32%).

CHECKMATE-238 demonstrated a statistically significant improvement in RFS for patients randomized to the intravenous nivolumab arm compared with the ipilimumab 10 mg/kg arm. Efficacy results are shown in Table 52 and Figure 9.

Neoadjuvant Treatment Of Resectable Non-Small Cell Lung Cancer

The effectiveness of OPDIVO QVANTIG has been established for the neoadjuvant treatment of resectable (tumors ≥4 cm or node positive) NSCLC in combination with platinum doublet chemotherapy. Use of OPDIVO QVANTIG for this indication is supported by evidence from adequate and well-controlled studies conducted with intravenous nivolumab (CHECKMATE-816, NCT02998528), and additional pharmacokinetic and safety data that demonstrated comparable pharmacokinetics and safety profiles between OPDIVO QVANTIG and intravenous nivolumab [see ADVERSE REACTIONS and CLINICAL PHARMACOLOGY]. Below is a description of the efficacy results of the adequate and well-controlled study of intravenous nivolumab in this lung cancer population.

CHECKMATE-816

CHECKMATE-816 (NCT02998528) was a randomized, open label trial in patients with resectable NSCLC. The trial included patients with resectable, histologically confirmed Stage IB (≥4 cm), II, or IIIA NSCLC (per the 7th edition American Joint Committee on Cancer/Union for International Cancer Control (AJCC/UICC) staging criteria), ECOG performance status 0 or 1, and measurable disease (per RECIST version 1.1). Patients with unresectable or metastatic NSCLC, known EGFR mutations or ALK translocations, Grade 2 or greater peripheral neuropathy, active autoimmune disease, or medical conditions requiring systemic immunosuppression were excluded from the study. Patients were randomized to receive either:

• nivolumab 360 mg administered intravenously over 30 minutes and platinum-doublet chemotherapy administered intravenously every 3 weeks for up to 3 cycles, or
• platinum-doublet chemotherapy administered every 3 weeks for up to 3 cycles.

Platinum-doublet chemotherapy consisted of paclitaxel 175 mg/m² or 200 mg/m² and carboplatin AUC 5 or AUC 6 (any histology); pemetrexed 500 mg/m² and cisplatin 75 mg/m² (non-squamous histology); or gemcitabine 1000 mg/m² or 1250 mg/m² and cisplatin 75 mg/m² (squamous histology). In the platinum-doublet chemotherapy arm, two additional treatment regimen options included vinorelbine 25 mg/m² or 30 mg/m² and cisplatin 75 mg/m²; or docetaxel 60 mg/m² or 75 mg/m² and cisplatin 75 mg/m² (any histology).

Stratification factors for randomization were tumor PD-L1 expression level (≥1% versus <1% or non-quantifiable), disease stage (IB/II versus IIIA), and sex (male versus female). Tumor assessments were performed at baseline, within 14 days of surgery, every 12 weeks after surgery for 2 years, then every 6 months for 3 years, and every year for 5 years until disease recurrence or progression. The major efficacy outcome measures were event-free survival (EFS) based on blinded independent central review (BICR) assessment and pathologic complete response (pCR) as evaluated by blinded independent pathology review (BIPR). Additional efficacy outcome measures included OS.

A total of 358 patients were randomized to receive either intravenous nivolumab in combination with platinum-doublet chemotherapy (n=179) or platinum-doublet chemotherapy (n=179). The median age was 65 years (range: 34 to 84) with 51% of patients ≥65 years and 7% of patients ≥75 years, 50% were Asian, 47% were White, 2% were Black, and 71% were male. Baseline ECOG performance status was 0 (67%) or 1 (33%); 50% had tumors with PD-L1 expression ≥1%; 35% had stage IB/II and 64% had stage IIIA disease; 51% had tumors with squamous histology and 49% had tumors with non-squamous histology; and 89% were former/current smokers.

Eighty-three percent of patients in the intravenous nivolumab in combination with platinum-doublet chemotherapy arm had definitive surgery compared to 75% of patients in the platinum-doublet chemotherapy arm.

The study demonstrated statistically significant improvements in EFS and pCR. Efficacy results are presented in Table 53 and Figure 10.

Neoadjuvant And Adjuvant Treatment Of Resectable Non-Small Cell Lung Cancer

The effectiveness of OPDIVO QVANTIG has been established for neoadjuvant treatment of resectable (tumors ≥4 cm or node positive) NSCLC and no EGFR mutations or ALK rearrangements in combination with platinum doublet chemotherapy followed by adjuvant treatment with intravenous nivolumab. Use of OPDIVO QVANTIG for this indication is supported by evidence from adequate and well-controlled studies conducted with intravenous nivolumab (CHECKMATE-77T, NCT04025879), and additional pharmacokinetic and safety data that demonstrated comparable pharmacokinetics and safety profiles between OPDIVO QVANTIG and intravenous nivolumab [see ADVERSE REACTIONS and CLINICAL PHARMACOLOGY]. Below is a description of the efficacy results of the adequate and well-controlled study of intravenous nivolumab in this lung cancer population.

CHECKMATE-77T

The efficacy of intravenous nivolumab, in combination with platinum-doublet chemotherapy, followed by surgery, and continued adjuvant treatment with intravenous nivolumab as a single agent, was investigated in CHECKMATE-77T (NCT04025879), a randomized, double-blind trial in 461 patients with resectable NSCLC. The trial included patients with resectable, suspected or histologically confirmed Stage IIA (>4 cm) to IIIB (T3-T4 N2) NSCLC (per the 8th edition American Joint Committee on Cancer (AJCC) Staging Manual), and ECOG performance status 0 or 1. Patients with unresectable or metastatic NSCLC, EGFR mutations or known ALK translocations, brain metastasis, Grade 2 or greater peripheral neuropathy, interstitial lung disease or active, non-infectious pneumonitis (symptomatic and/or requiring treatment), active autoimmune disease, or medical conditions requiring systemic immunosuppression were excludedfrom the study. Randomization was stratified by tumor PD-L1 expression level (≥1% versus <1% versus indeterminate/not evaluable), disease stage (Stage II versus Stage III), and tumor histology (squamous versus nonsquamous).

Patients were randomized (1:1) to receive either:

• Neoadjuvant nivolumab 360 mg administered intravenously over 30 minutes in combination with one of the following platinum-doublet chemotherapy regimens every 3 weeks for four cycles:
  • Paclitaxel 175 mg/m² or 200 mg/m² and carboplatin AUC 5 or AUC 6 (any histology)
  • Pemetrexed 500 mg/m², and cisplatin 75 mg/m² or carboplatin AUC 5 or AUC 6 (nonsquamous histology)
  • Cisplatin 75 mg/m² and docetaxel 75 mg/m² (squamous histology).

Within 90 days after the surgery, nivolumab 480 mg was administered intravenously over 30 minutes every 4 weeks. or

• Neoadjuvant placebo administered intravenously over 30 minutes in combination with platinum-doublet chemotherapy (see above) every 3 weeks for four cycles. Within 90 days after the surgery, placebo was administered intravenously over 30 minutes every 4 weeks.

All study medications were administered via intravenous infusion. Treatment continued until disease progression, recurrence, or unacceptable toxicity for up to 13 cycles (1 year). Tumor assessments were performed every 12 weeks for 2 years, then every 24 weeks for up to 5 years or until disease recurrence or progression was confirmed by BICR.

The trial was not designed to isolate the effect of intravenous nivolumab in each phase (neoadjuvant or adjuvant) of treatment.

The major efficacy outcome measure was event-free survival (EFS) based on BICR assessment. Additional efficacy outcome measures included overall survival (OS), pathologic complete response (pCR), and major pathologic response (MPR). 

The median age was 66 years (range: 35 to 86); 71% were male; 72% were White, 25% were Asian, 1.7% were Black, and 1.5% were mixed race/ race unknown/ not reported; and 6% were Hispanic or Latino. Baseline ECOG performance status was 0 (62%) or 1 (38%); 56% had tumors with PD-L1 expression ≥1% and 40% had tumors with PD-L1 expression <1%; 35% had stage II and 64% had stage III disease; 23% had N1 disease and 39% had N2 disease; 51% had tumors with squamous histology and 49% had tumors with nonsquamous histology; and 90% were former/current smokers.

Seventy-eight percent of patients in the neoadjuvant intravenous nivolumab in combination with platinum-doublet chemotherapy followed by adjuvant intravenous nivolumab arm had definitive surgery compared to 77% of patients in the neoadjuvant placebo and platinum-doublet chemotherapy followed by placebo arm.

The study demonstrated a statistically significant improvement in EFS for patients treated with neoadjuvant intravenous nivolumab in combination with platinum-doublet chemotherapy followed by single agent intravenous nivolumab compared with patients randomized to placebo in combination with platinum-doublet chemotherapy followed by placebo. Efficacy results are presented in Table 54 and Figure 11.

In a pre-specified descriptive analysis, the pCR rate was 25% (95% CI: 20, 31) in the intravenous nivolumab arm and 4.7% (95% CI: 2.4, 8) in the placebo arm.

At the time of the EFS analysis, OS data were immature.

Metastatic Non-Small Cell Lung Cancer

Second-line Treatment Of Metastatic NSCLC

The effectiveness of OPDIVO QVANTIG has been established for the treatment of NSCLC previously treated with platinum-based chemotherapy. Patients with EGFR or ALK genomic tumor aberrations should have disease progression on FDA-approved therapy for these aberrations prior to receiving OPDIVO QVANTIG. Use of OPDIVO QVANTIG for this indication is supported by evidence from adequate and well-controlled studies conducted with intravenous nivolumab, and additional pharmacokinetic and safety data that demonstrated comparable pharmacokinetics and safety profiles between OPDIVO QVANTIG and intravenous nivolumab [see ADVERSE REACTIONS and CLINICAL PHARMACOLOGY]. Below is a description of the efficacy results of this adequate and well-controlled study of intravenous nivolumab in this lung cancer population.

CHECKMATE-017

CHECKMATE-017 (NCT01642004) was a randomized (1:1), open-label trial in 272 patients with metastatic squamous NSCLC who had experienced disease progression during or after one prior platinum doublet-based chemotherapy regimen. Patients received nivolumab 3 mg/kg by intravenous infusion every 2 weeks (n=135) or docetaxel 75 mg/m² intravenously every 3 weeks (n=137). Randomization was stratified by prior paclitaxel vs. other prior treatment and region (US/Canada vs. Europe vs. Rest of World). This trial included patients regardless of their PD-L1 status. The trial excluded patients with autoimmune disease, medical conditions requiring systemic immunosuppression, symptomatic interstitial lung disease, or untreated brain metastasis. Patients with treated brain metastases were eligible if neurologically returned to baseline at least 2 weeks prior to enrollment, and either off corticosteroids, or on a stable or decreasing dose of <10 mg daily prednisone equivalents. The first tumor assessments were conducted 9 weeks after randomization and continued every 6 weeks thereafter. The major efficacy outcome measure was OS. Additional efficacy outcome measures were investigatorassessed ORR and PFS.

The trial population characteristics were: median age was 63 years (range: 39 to 85) with 44% ≥65 years of age and 11% ≥75 years of age. The majority of patients were White (93%) and male (76%); the majority of patients were enrolled in Europe (57%) with the remainder in US/Canada (32%) and the rest of the world (11%). Baseline ECOG performance status was 0 (24%) or 1 (76%) and 92% were former/current smokers. Baseline disease characteristics of the population as reported by investigators were Stage IIIb (19%), Stage IV (80%), and brain metastases (6%). All patients received prior therapy with a platinum-doublet regimen and 99% of patients had tumors of squamouscell histology.

The trial demonstrated a statistically significant improvement in OS for patients randomized to intravenous nivolumab as compared with docetaxel at the prespecified interim analysis when 199 events were observed (86% of the planned number of events for final analysis). Efficacy results are shown in Table 55 and Figure 12.

Figure 12: Overall Survival - CHECKMATE-017

Archival tumor specimens were retrospectively evaluated for PD-L1 expression. Across the trial population, 17% of 272 patients had non-quantifiable results. Among the 225 patients with quantifiable results, 47% had PD-L1 negative squamous NSCLC, defined as <1% of tumor cells expressing PD-L1 and 53% had PD-L1 positive squamous NSCLC defined as ≥1% of tumor cells expressing PD-L1. In pre-specified exploratory subgroup analyses, the hazard ratios for survival were 0.58 (95% CI: 0.37, 0.92) in the PD-L1 negative subgroup and 0.69 (95% CI: 0.45, 1.05) in the PD-L1 positive subgroup.

CHECKMATE-057

CHECKMATE-057 (NCT01673867) was a randomized (1:1), open-label trial in 582 patients with metastatic non-squamous NSCLC who had experienced disease progression during or after one prior platinum doublet-based chemotherapy regimen. Appropriate prior targeted therapy in patients with known sensitizing EGFR mutation or ALK translocation was allowed. Patients received nivolumab 3 mg/kg by intravenous infusion every 2 weeks (n=292) or docetaxel 75 mg/m² intravenously every 3 weeks (n=290). Randomization was stratified by prior maintenance therapy (yes vs. no) and number of prior therapies (1 vs. 2). The trial excluded patients with autoimmune disease, medical conditions requiring systemic immunosuppression, symptomatic interstitial lung disease, or untreated brain metastasis. Patients with treated brain metastases were eligible if neurologically stable. The first tumor assessments were conducted 9 weeks after randomization and continued every 6 weeks thereafter. The major efficacy outcome measure was OS. Additional efficacy outcome measures were investigator-assessed ORR and PFS. In addition, prespecified analyses were conducted in subgroups defined by PD-L1 expression.

The trial population characteristics: median age was 62 years (range: 21 to 85) with 42% of patients ≥65 years and 7% of patients ≥75 years. The majority of patients were White (92%) and male (55%); the majority of patients were enrolled in Europe (46%) followed by the US/Canada (37%) and the rest of the world (17%). Baseline ECOG performance status was 0 (31%) or 1 (69%), 79% were former/current smokers, 3.6% had NSCLC with ALK rearrangement, 14% had NSCLC with EGFR mutation, and 12% had previously treated brain metastases. Prior therapy included platinum-doublet regimen (100%) and 40% received maintenance therapy as part of the first-line regimen. Histologic subtypes included adenocarcinoma (93%), large cell (2.4%), and bronchoalveolar (0.9%).

CHECKMATE-057 demonstrated a statistically significant improvement in OS for patients randomized to intravenous nivolumab as compared with docetaxel at the prespecified interim analysis when 413 events were observed (93% of the planned number of events for final analysis). Efficacy results are shown in Table 56 and Figure 13.

Archival tumor specimens were evaluated for PD-L1 expression following completion of the trial. Across the trial population, 22% of 582 patients had non-quantifiable results. Of the remaining 455 patients, the proportion of patients in retrospectively determined subgroups based on PD-L1 testing using the PD-L1 IHC 28-8 pharmDx assay were: 46% PD-L1 negative, defined as <1% of tumor cells expressing PD-L1 and 54% had PD-L1 expression, defined as ≥1% of tumor cells expressing PD-L1. Among the 246 patients with tumors expressing PD-L1, 26% had ≥1% but <5% tumor cells with positive staining, 7% had ≥5% but <10% tumor cells with positive staining, and 67% had ≥10% tumor cells with positive staining. Figures 14 and 15 summarize the results of prespecified analyses of OS and PFS in subgroups determined by percentage of tumor cells expressing PD-L1.

Recurrent Or Metastatic Squamous Cell Carcinoma Of The Head And Neck

The effectiveness of OPDIVO QVANTIG has been established for the treatment of recurrent or metastatic squamous cell carcinoma of the head and neck with disease progression on or after platinum-based therapy. Use of OPDIVO QVANTIG for this indication is supported by evidence from an adequate and well-controlled study conducted with intravenous nivolumab, and additional pharmacokinetic and safety data that demonstrated comparable pharmacokinetics and safety profiles between OPDIVO QVANTIG and intravenous nivolumab [see ADVERSE REACTIONS and CLINICAL PHARMACOLOGY]. Below is a description of the efficacy results of the adequate and well-controlled study of intravenous nivolumab in this head and neck carcinoma population.

CHECKMATE-141

CHECKMATE-141 (NCT02105636) was a randomized (2:1), active-controlled, open-label trial enrolling patients with metastatic or recurrent SCCHN who had experienced disease progression during or within 6 months of receiving platinum-based therapy administered in either the adjuvant, neo-adjuvant, primary (unresectable locally advanced) or metastatic setting. The trial excluded patients with autoimmune disease, medical conditions requiring immunosuppression, recurrent or metastatic carcinoma of the nasopharynx, squamous cell carcinoma of unknown primary histology, salivary gland or non-squamous histologies (e.g., mucosal melanoma), or untreated brain metastasis. Patients with treated brain metastases were eligible if neurologically stable. Patients were randomized to receive nivolumab 3 mg/kg by intravenous infusion every 2 weeks or investigator’s choice of cetuximab (400 mg/m² initial dose intravenously followed by 250 mg/m² weekly), or methotrexate (40 to 60 mg/m² intravenously weekly), or docetaxel (30 to 40 mg/m² intravenously weekly).

Randomization was stratified by prior cetuximab treatment (yes/no). The first tumor assessments were conducted 9 weeks after randomization and continued every 6 weeks thereafter. The major efficacy outcome measure was OS. Additional efficacy outcome measures were PFS and ORR.

A total of 361 patients were randomized; 240 patients to the intravenous nivolumab arm and 121 patients to the investigator’s choice arm (docetaxel: 45%; methotrexate: 43%; and cetuximab: 12%). The trial population characteristics were: median age was 60 years (range: 28 to 83) with 31% ≥65 years of age, 83% were White, 12% Asian, and 4% were Black, and 83% male. Baseline ECOG performance status was 0 (20%) or 1 (78%), 76% were former/current smokers, 90% had Stage IV disease, 45% of patients received only one prior line of systemic therapy, the remaining 55% received two or more prior lines of systemic therapy, and 25% had HPVp16-positive tumors, 24% had HPV p16-negative tumors, and 51% had unknown status.

The trial demonstrated a statistically significant improvement in OS for patients randomized to intravenous nivolumab as compared with investigator’s choice at a pre-specified interim analysis (78% of the planned number of events for final analysis). There were no statistically significant differences between the two arms for PFS (HR=0.89; 95% CI: 0.70, 1.13) or ORR (13.3% [95% CI: 9.3, 18.3] vs. 5.8% [95% CI: 2.4, 11.6] for nivolumab and investigator’s choice, respectively). Efficacy results are shown in Table 57 and Figure 16.

Archival tumor specimens were retrospectively evaluated for PD-L1 expression using the PD-L1 IHC 28-8 pharmDx assay. Across the trial population, 28% (101/361) of patients had non-quantifiable results. Among the 260 patients with quantifiable results, 43% (111/260) had PD-L1 negative SCCHN, defined as <1% of tumor cells expressing PD-L1, and 57% (149/260) had PD-L1 positive SCCHN, defined as ≥1% of tumor cells expressing PD-L1. In pre-specified exploratory subgroup analyses, the hazard ratio for survival was 0.89 (95% CI: 0.54, 1.45) with median survivals of 5.7 and 5.8 months for the nivolumab and chemotherapy arms, respectively, in the PD-L1 negative subgroup. The HR for survival was 0.55 (95% CI: 0.36, 0.83) with median survivals of 8.7 and 4.6 months for the nivolumab and chemotherapy arms, respectively, in the PD-L1 positive SCCHN subgroup.

Urothelial Carcinoma

Adjuvant Treatment Of Urothelial Carcinoma (UC) At High Risk Of Recurrence

The effectiveness of OPDIVO QVANTIG has been established for the adjuvant treatment of UC at high risk of recurrence. Use of OPDIVO QVANTIG for this indication is supported by evidence from an adequate and well-controlled study conducted with intravenous nivolumab, and additional pharmacokinetic and safety data that demonstrated comparable pharmacokinetics and safety profiles between OPDIVO QVANTIG and intravenous nivolumab [see ADVERSE REACTIONS and CLINICAL PHARMACOLOGY]. Below is a description of the efficacy results of the adequate and well-controlled study of intravenous nivolumab in this UC population.

CHECKMATE-274

CHECKMATE-274 (NCT02632409) was a randomized, double-blind, placebo-controlled study of adjuvant intravenous nivolumab in patients who were within 120 days of radical resection (R0) of UC of the bladder or upper urinary tract (renal pelvis or ureter) at high risk of recurrence. High risk of recurrence was defined as either 1) ypT2-ypT4a or ypN+ for patients who received neoadjuvant cisplatin or 2) pT3-pT4a or pN+ for patients who did not receive neoadjuvant cisplatin and who also either were ineligible for or refused adjuvant cisplatin. Patients were randomized 1:1 to receive nivolumab 240 mg or placebo by intravenous infusion every 2 weeks until recurrence or until unacceptable toxicity for a maximum treatment duration of 1 year. Patients were stratified by pathologic nodal status (N+ vs. N0/x with <10 nodes removed vs. N0 with ≥10 nodes removed), tumor cells expressing PD-L1 (≥1% vs. <1%/indeterminate as determined by the central lab using the PD-L1 IHC 28-8 pharmDx assay), and use of neoadjuvant cisplatin (yes vs. no).

The trial population characteristics were: median age of 67 years (range: 30 to 92); 76% male; 76% White, 22% Asian, 0.7% Black, and 0.1% American Indian or Alaska Native. Of the 335 (47%) of patients with node-positive UC, 44 (6%) had non–muscleinvasive (<pT2) primary tumors. ECOG performance status was 0 (63%), 1 (35%), or 2 (2%). Prior neoadjuvant cisplatin had been given to 43% of patients; of the 57% who did not receive prior neoadjuvant cisplatin, reasons listed were ineligibility (22%), patient preference (33%), and other/not reported (2%). Tumor PD-L1 expression was ≥1% in 40% of patients, and 21% of patients had upper tract UC.

The major efficacy outcome measures were investigator-assessed DFS in all randomized patients and in patients with tumors expressing PD-L1 ≥1%. DFS was defined as time to first recurrence (local urothelial tract, local non-urothelial tract, or distant metastasis), or death. Additional efficacy outcome measures included OS.

At the pre-specified interim analysis, CHECKMATE-274 demonstrated a statistically significant improvement in DFS for patients randomized to intravenous nivolumab vs. placebo in the all randomized patient population, as well as in the subpopulation of patients with PD-L1 ≥1%, as shown in Table 58 and Figure 17.

In exploratory subgroup analyses in patients with upper tract UC (n=149), no improvement in DFS was observed in the nivolumab arm compared to the placebo arm. The unstratified DFS hazard ratio estimate was 1.15 (95% CI: 0.74, 1.80).

In an exploratory subgroup analysis in patients with PD-L1 expression of <1% (n=414), the unstratified DFS hazard ratio estimate was 0.83 (95% CI: 0.64, 1.08).

OS data is immature with 33% of deaths in the overall randomized population. In the UTUC subpopulation, 37 deaths occurred (20 in the nivolumab arm, 17 in the placebo arm).

First-line Treatment Of Unresectable Or Metastatic UC

The effectiveness of OPDIVO QVANTIG has been established for the first-line treatment of unresectable or metastatic UC in combination with cisplatin and gemcitabine. Use of OPDIVO QVANTIG for this indication is supported by evidence from an adequate and wellcontrolled study conducted with intravenous nivolumab, and additional pharmacokinetic and safety data that demonstrated comparable pharmacokinetics and safety profiles between OPDIVO QVANTIG and intravenous nivolumab [see ADVERSE REACTIONS and CLINICAL PHARMACOLOGY]. Below is a description of the efficacy results of the adequate and well-controlled study of intravenous nivolumab in this UC population.

CHECKMATE-901

CHECKMATE-901 (NCT 03036098) was a randomized, open-label study in patients with previously untreated unresectable or metastatic UC. Prior neoadjuvant or adjuvant chemotherapy were permitted as long as the disease recurrence took place ≥12 months from completion of therapy. Patients who were ineligible for cisplatin and those with active CNS metastases were excluded. Stratification factors for randomization were PD-L1 status (≥1% vs. <1% or indeterminate) and liver metastasis. Patients were randomized 1:1 to receive either:

• Intravenous nivolumab 360 mg and cisplatin 70 mg/m² on Day 1 and gemcitabine 1000 mg/m² on Days 1 and 8 of a 21-day cycle of a 21-day cycle for up to 6 cycles followed by single-agent intravenous nivolumab 480 mg every 4 weeks until disease progression or unacceptable toxicity. In the absence of disease progression or unacceptable toxicity, intravenous nivolumab was continued for up to 2 years from first dose.
• Cisplatin 70 mg/m² on Day 1 and gemcitabine 1000 mg/m² on Days 1 and 8 of a 21-day cycle for up to 6 cycles, until disease progression or unacceptable toxicity.

The major efficacy outcome measures were OS and PFS as assessed by BICR using RECIST v1.1. Additional efficacy outcome measures included ORR as assessed by BICR.

The median age was 65 years of age (range: 32 to 86) with 51% of patients ≥65 years of age and 12% of patients ≥75 years of age, 23% were Asian, 72% were White, 0.3% were Black, 0.3% were American Indian or Alaska Native, 4.9% were Other, 12% were Hispanic or Latino, and 77% were male. Baseline ECOG performance status was 0 (53%) or 1 (46%). At baseline, 87% of patients had metastatic UC, including 20% with liver metastases, 11% had locally advanced UC, and 51% had UC histologic variants. Forty-nine (16%) in the intravenous nivolumab in combination with cisplatin-based chemotherapy arm and 43 (14%) in the cisplatin-based chemotherapy arm switched from cisplatin to carboplatin after at least one cycle of cisplatin.

Previously Treated Advanced Or Metastatic Urothelial Carcinoma

The effectiveness of OPDIVO QVANTIG has been established for the treatment of patients with locally advanced or metastatic UC and disease progression during or following platinum-containing chemotherapy or within 12 months of neoadjuvant or adjuvant treatment with platinum-containing chemotherapy. Use of OPDIVO QVANTIG for this indication is supported by evidence from an adequate and well-controlled study conducted with intravenous nivolumab, and additional pharmacokinetic and safety data that demonstrated comparable pharmacokinetics and safety profiles between OPDIVO QVANTIG and intravenous nivolumab [see ADVERSE REACTIONS and CLINICAL PHARMACOLOGY]. Below is a description of the efficacy results of the adequate and well-controlled study of intravenous nivolumab in this UC population.

CHECKMATE-275

CHECKMATE-275 (NCT02387996) was a single-arm trial in 270 patients with locally advanced or metastatic UC who had disease progression during or following platinumcontaining chemotherapy or who had disease progression within 12 months of treatment with a platinum-containing neoadjuvant or adjuvant chemotherapy regimen. Patients were excluded for active brain or leptomeningeal metastases, active autoimmune disease, medical conditions requiring systemic immunosuppression, and ECOG performance status >1. Patients received nivolumab 3 mg/kg by intravenous infusion every 2 weeks until unacceptable toxicity or either radiographic or clinical progression. Tumor response assessments were conducted every 8 weeks for the first 48 weeks and every 12 weeks thereafter. Major efficacy outcome measures included confirmed ORR as assessed by IRRC using RECIST v1.1 and DOR.

The median age was 66 years (range: 38 to 90), 78% were male, 86% were White. Twenty-seven percent had non-bladder urothelial carcinoma and 84% had visceral metastases. Thirty-four percent of patients had disease progression following prior platinum-containing neoadjuvant or adjuvant therapy. Twenty-nine percent of patients had received ≥2 prior systemic regimens in the metastatic setting. Thirty-six percent of patients received prior cisplatin only, 23% received prior carboplatin only, and 7% were treated with both cisplatin and carboplatin in the metastatic setting. Forty-six percent of patients had an ECOG performance status of 1. Eighteen percent of patients had a hemoglobin <10 g/dL, and twenty-eight percent of patients had liver metastases at baseline. Patients were included regardless of their PD-L1 status.

Tumor specimens were evaluated prospectively using the PD-L1 IHC 28-8 pharmDx assay at a central laboratory and the results were used to define subgroups for pre-specified analyses. Of the 270 patients, 46% were defined as having PD-L1 expression of ≥1% (defined as ≥1% of tumor cells expressing PD-L1). The remaining 54% of patients were classified as having PD-L1 expression of <1% (defined as <1% of tumor cells expressing PD-L1). Confirmed ORR in all patients and the two PD-L1 subgroups are shown in Table 60. Median time to response was 1.9 months (range: 1.6-7.2). In 77 patients who received prior systemic therapy only in the neoadjuvant or adjuvant setting, the ORR was 23.4% (95% CI: 14.5%, 34.4%).

Microsatellite Instability-High Or Mismatch Repair Deficient Metastatic Colorectal Cancer

The effectiveness of OPDIVO QVANTIG has been established for the treatment of microsatellite instability-high or mismatch repair deficient colorectal cancer (CRC) that has progressed following treatment with a fluoropyrimidine, oxaliplatin, and irinotecan. Use of OPDIVO QVANTIG for this indication is supported by evidence from an adequate and well-controlled study conducted with intravenous nivolumab (CHECKMATE-142, NCT02060188), and additional pharmacokinetic and safety data that demonstrated comparable pharmacokinetics and safety profiles between OPDIVO QVANTIG and intravenous nivolumab [see ADVERSE REACTIONS and CLINICAL PHARMACOLOGY]. Below is a description of the efficacy results of the adequate and well-controlled study of intravenous nivolumab in this CRC population.

OPDIVO QVANTIG is not indicated for the treatment of pediatric patients.

CHECKMATE-142

CHECKMATE-142 (NCT02060188) was a multicenter, non-randomized, multiple parallelcohort, open-label trial conducted in patients with locally determined dMMR or MSI-H metastatic CRC (mCRC) who had disease progression during or after prior treatment with fluoropyrimidine-, oxaliplatin-, or irinotecan-based chemotherapy. Key eligibility criteria were at least one prior line of treatment for metastatic disease, ECOG performance status 0 or 1, and absence of the following: active brain metastases, active autoimmune disease, or medical conditions requiring systemic immunosuppression.

Patients enrolled in the single agent intravenous nivolumab MSI-H mCRC cohort received nivolumab 3 mg/kg by intravenous infusion (IV) every 2 weeks. Patients enrolled in the intravenous nivolumab and ipilimumab MSI-H mCRC cohort received nivolumab 3 mg/kg and ipilimumab 1 mg/kg intravenously every 3 weeks for 4 doses, followed by nivolumab as a single agent at a dose of 3 mg/kg as intravenous infusion every 2 weeks. Treatment in both cohorts continued until unacceptable toxicity or radiographic progression.

Tumor assessments were conducted every 6 weeks for the first 24 weeks and every 12 weeks thereafter. Efficacy outcome measures included ORR and DOR as assessed by BICR using RECIST v1.1.

A total of 74 patients were enrolled in the single-agent MSI-H mCRC intravenous nivolumab cohort. The median age was 53 years (range: 26 to 79) with 23% ≥65 years of age and 5% ≥75 years of age, 59% were male and 88% were White. Baseline ECOG performance status was 0 (43%), 1 (55%), or 3 (1.4%) and 36% were reported to have Lynch Syndrome. Across the 74 patients, 72% received prior treatment with a fluoropyrimidine, oxaliplatin, and irinotecan; 7%, 30%, 28%, 19%, and 16% received 0, 1, 2, 3, or ≥4 prior lines of therapy for metastatic disease, respectively, and 42% of patients had received an anti-EGFR antibody.

A total of 119 patients were enrolled in the intravenous nivolumab and ipilimumab MSI-H mCRC cohort. The median age was 58 years (range: 21 to 88), with 32% ≥65 years of age and 9% ≥75 years of age; 59% were male and 92% were White. Baseline ECOG performance status was 0 (45%) and 1 (55%), and 29% were reported to have Lynch Syndrome. Across the 119 patients, 69% had received prior treatment with a fluoropyrimidine, oxaliplatin, and irinotecan; 10%, 40%, 24%, and 15% received 1, 2, 3, or ≥4 prior lines of therapy for metastatic disease, respectively, and 29% had received an anti-EGFR antibody.

Efficacy results for each of these single-arm cohorts are shown in Table 61.

Hepatocellular Carcinoma

The effectiveness of OPDIVO QVANTIG has been established for the treatment of hepatocellular carcinoma in patients who have been previously treated with sorafenib and following treatment with intravenous nivolumab and ipilimumab. Use of OPDIVO QVANTIG for this indication is supported by evidence from an adequate and wellcontrolled study conducted with intravenous nivolumab, and additional pharmacokinetic and safety data that demonstrated comparable pharmacokinetics and safety profiles between OPDIVO QVANTIG and intravenous nivolumab [see ADVERSE REACTIONS and CLINICAL PHARMACOLOGY]. Below is a description of the efficacy results of the adequate and well-controlled study of intravenous nivolumab in this hepatocellular carcinoma population.

CHECKMATE-040

CHECKMATE-040 (NCT01658878) was a multicenter, multiple cohort, open-label trial that evaluated the efficacy of intravenous nivolumab as a single agent and in combination with ipilimumab in patients with hepatocellular carcinoma (HCC) who progressed on or were intolerant to sorafenib. Additional eligibility criteria included histologic confirmation of HCC and Child-Pugh Class A cirrhosis. The trial excluded patients with active autoimmune disease, brain metastasis, a history of hepatic encephalopathy, clinically significant ascites, infection with HIV, or active co-infection with hepatitis B virus (HBV) and hepatitis C virus (HCV) or HBV and hepatitis D virus (HDV); however, patients with only active HBV or HCV were eligible.

Tumor assessments were conducted every 6 weeks for 48 weeks and then every 12 weeks thereafter. The major efficacy outcome measure was confirmed overall response rate as assessed by BICR using RECIST v1.1 and modified RECIST (mRECIST) for HCC. Duration of response was also assessed.

The efficacy of intravenous nivolumab in combination with ipilimumab was evaluated in 49 patients (Cohort 4) who received intravenous nivolumab 1 mg/kg and ipilimumab 3 mg/kg administered every 3 weeks for 4 doses, followed by single-agent intravenous nivolumab at 240 mg every 2 weeks until disease progression or unacceptable toxicity. The median age was 60 years (range: 18 to 80), 88% were male, 74% were Asian, and 25% were White. Baseline ECOG performance status was 0 (61%) or 1 (39%). Fiftyseven (57%) percent of patients had active HBV infection, 8% had active HCV infection, and 35% had no evidence of active HBV or HCV. The etiology for HCC was alcoholic liver disease in 16% and non-alcoholic fatty liver disease in 6% of patients. Child-Pugh class and score was A5 for 82% and A6 for 18%; 80% of patients had extrahepatic spread; 35% had vascular invasion; and 51% had AFP levels ≥400 μg/L. Prior cancer treatment history included surgery (74%), radiotherapy (29%), or local treatment (59%). All patients had received prior sorafenib, of whom 10% were unable to tolerate sorafenib; 29% of patients had received 2 or more prior systemic therapies.

Efficacy results are shown in Table 62. The results for intravenous nivolumab in combination with ipilimumab in Cohort 4 are based on a minimum follow-up of 28 months.

Esophageal Cancer

Adjuvant Treatment Of Resected Esophageal Or Gastroesophageal Junction Cancer

The effectiveness of OPDIVO QVANTIG has been established for the adjuvant treatment of resected esophageal or gastroesophageal junction cancer with residual pathologic disease who have received neoadjuvant chemoradiotherapy (CRT). Use of OPDIVO QVANTIG for this indication is supported by evidence from an adequate and well controlled study conducted with intravenous nivolumab, and additional pharmacokinetic and safety data that demonstrated comparable pharmacokinetics and safety profiles between OPDIVO QVANTIG and intravenous nivolumab [see ADVERSE REACTIONS and CLINICAL PHARMACOLOGY]. Below is a description of the efficacy results of the adequate and well-controlled study of intravenous nivolumab in this esophageal or gastroesophageal junction cancer population.

CHECKMATE-577

CHECKMATE-577 (NCT02743494) was a randomized, multicenter, double-blind trial in 794 patients with completely resected (negative margins) esophageal or gastroesophageal junction cancer who had residual pathologic disease following concurrent chemoradiotherapy (CRT). Patients were randomized (2:1) to receive either nivolumab 240 mg or placebo by intravenous infusion over 30 minutes every 2 weeks for 16 weeks followed by 480 mg or placebo by intravenous infusion over 30 minutes every 4 weeks beginning at week 17. Treatment was until disease recurrence, unacceptable toxicity, or for up to 1 year in total duration. Enrollment required complete resection within 4 to 16 weeks prior to randomization. The trial excluded patients who did not receive CRT prior to surgery, had stage IV resectable disease, autoimmune disease, or any condition requiring systemic treatment with either corticosteroids (>10 mg daily prednisone or equivalent) or other immunosuppressive medications. Randomization was stratified by tumor PD-L1 status (≥1% vs. <1% or indeterminate or non-evaluable), pathologic lymph node status (positive ≥ypN1 vs. negative ypN0), and histology (squamous vs. adenocarcinoma). The major efficacy outcome measure was disease-free survival (DFS) defined as the time between the date of randomization and the date of first recurrence (local, regional, or distant from the primary resected site) or death, from any cause, whichever occurred first as assessed by the investigator prior to subsequent anti-cancer therapy. Patients on treatment underwent imaging for tumor recurrence every 12 weeks for 2 years, and a minimum of one scan every 6 to 12 months for years 3 to 5.

The trial population characteristics were: median age 62 years (range: 26 to 86), 36% were ≥65 years of age, 85% were male, 15% were Asian, 82% were White, and 1.1% were Black. Disease characteristics were AJCC Stage II (35%) or Stage III (65%) at initial diagnosis carcinoma, EC (60%) or GEJC (40%) at initial diagnosis, with pathologic positive lymph node status (58%) at study entry and histological confirmation of predominant adenocarcinoma (71%) or squamous cell carcinoma (29%). The baseline Tumor PD-L1 status ≥1% was positive for 16% of patients and negative for 72% of patients. Baseline ECOG performance status was 0 (58%) or 1 (42%).

CHECKMATE-577 demonstrated a statistically significant improvement in DFS for patients randomized to the intravenous nivolumab arm as compared with the placebo arm. DFS benefit was observed regardless of tumor PD-L1 expression and histology.

Efficacy results are shown in Table 63 and Figure 20.

First-line Treatment Of Unresectable Advanced Or Metastatic Esophageal Squamous Cell Carcinoma (ESCC)

The effectiveness of OPDIVO QVANTIG in combination with fluoropyrimidine- and platinum-containing chemotherapy has been established for the first-line treatment of unresectable advanced or metastatic ESCC. Use of OPDIVO QVANTIG for this indication is supported by evidence from an adequate and well-controlled study conducted with intravenous nivolumab, and additional pharmacokinetic and safety

data that demonstrated comparable pharmacokinetics and safety profiles between OPDIVO QVANTIG and intravenous nivolumab [see ADVERSE REACTIONS and CLINICAL PHARMACOLOGY]. Below is a description of the efficacy results of the adequate and well-controlled study of intravenous nivolumab in this esophageal squamous cell carcinoma population.

CHECKMATE-648

CHECKMATE-648 (NCT03143153) was a randomized, active-controlled, open-label trial in patients with previously untreated unresectable advanced, recurrent or metastatic ESCC (squamous or adenosquamous histology). The trial enrolled patients whose tumor was evaluable for tumor cell (TC) PD-L1 expression [also called PD-L1 tumor proportion score (TPS)], which was evaluated using the PD-L1 IHC 28-8 pharmDx assay at a central laboratory. A retrospective scoring of a patient’s tumor PD-L1 status using Combined Positive Score (CPS), was also conducted using the PD-L1-stained tumor specimens used for randomization. Patients were not amenable to chemoradiation or surgery with curative intent. Prior treatment with curative intent was allowed if completed more than six months prior to trial enrollment. The trial excluded patients with brain metastasis that were symptomatic, had active autoimmune disease, used systemic corticosteroids or immunosuppressants, or patients at high risk of bleeding or fistula due to apparent invasion of tumor to organs adjacent to the esophageal tumor. Patients were randomized to receive one of the following treatments:

• Intravenous nivolumab 240 mg on days 1 and 15, fluorouracil 800 mg/m²/day intravenously on days 1 through 5 (for 5 days), and cisplatin 80 mg/m² intravenously on day 1 (of a 4-week cycle).
• Intravenous nivolumab 3 mg/kg every 2 weeks in combination with ipilimumab 1 mg/kg every 6 weeks.
• Fluorouracil 800 mg/m²/day intravenously on days 1 through 5 (for 5 days), and cisplatin 80 mg/m² intravenously on day 1 (of a 4-week cycle).

Patients received intravenous nivolumab until disease progression, unacceptable toxicity, or up to 2 years. In patients who received intravenous nivolumab in combination with chemotherapy and in whom either fluorouracil and/or cisplatin were discontinued, other components of the treatment regimen were allowed to be continued. Patients who discontinued combination therapy because of an adverse reaction attributed to ipilimumab were permitted to continue intravenous nivolumab as a single agent.

Randomization was stratified by TC PD-L1 expression (≥1% vs. <1% or indeterminate), region (East Asia vs. Rest of Asia vs. Rest of World), ECOG performance status (0 vs. 1), and number of organs with metastases (≤1 vs. ≥2). The major efficacy outcome measures were OS and BICR-assessed PFS in patients with TC PD-L1 expression ≥1%.  Additional efficacy measures included OS in all randomized patients, BICR-assessed PFS in all randomized patients, and ORR assessed by BICR in TC PD-L1 expression ≥1% and in all randomized patients. The tumor assessments per RECIST v1.1 were conducted every 6 weeks up to and including week 48, then every 12 weeks thereafter.

A total of 970 patients were randomized in CHECKMATE-648 study among whom 965 and 906 patients had quantifiable TC PD-L1 expression and CPS at baseline, respectively. The trial population characteristics for all randomized patients were median age 64 years (range: 26 to 90), 47% were ≥65 years of age, 82% were male, 71% were Asian, 26% were White, and 1.1% were Black or African American. Patients had histological confirmation of squamous cell carcinoma (98%) or adenosquamous cell carcinoma (1.9%) in the esophagus. Baseline ECOG performance status was 0 (47.0%) or 1 (53%).

Efficacy results are shown in Table 64 and Figures 21 and 22.

Figure 22: Progression-free Survival - CHECKMATE-648

Exploratory subgroup analyses of patients with TC PD-L1 expression <1% (n=492) were conducted. OS results for each intravenous nivolumab containing arm compared to chemotherapy were:

• Intravenous Nivolumab with Chemotherapy (n=163) vs. Chemotherapy (n=165): unstratified OS HR was 0.99 (95% CI: 0.76, 1.29) with median OS of 12 months (95% CI: 9.9, 15.5) on the Intravenous Nivolumab with Chemotherapy arm and 12.2 months (95% CI: 10.7, 14) on the Chemotherapy arm
• Intravenous Nivolumab with Ipilimumab (n=164) vs. Chemotherapy (n=165): unstratified OS HR was 0.97 (95% CI: 0.74, 1.26) with median OS of 12 months (95% CI: 10.1, 16.0) on the Intravenous Nivolumab with Ipilimumab arm and 12.2 months (95% CI: 10.7, 14) on the Chemotherapy arm

Exploratory subgroup analyses were also conducted by PD-L1 status per CPS (≥1 and <1) for each intravenous nivolumab containing arm compared to chemotherapy. Among the 906 patients with quantifiable PD-L1 CPS at baseline, 278 in the intravenous nivolumab with chemotherapy arm, 266 in the intravenous nivolumab with ipilimumab arm, and 280 in the chemotherapy arm had PD-L1 CPS ≥1. A total of 27 patients in the intravenous nivolumab with chemotherapy arm, 31 patients in the intravenous nivolumab with ipilimumab arm, and 24 patients in the chemotherapy arm had PD-L1 CPS <1.

OS results for each comparison by PD-L1 CPS status were:

• Intravenous Nivolumab with Chemotherapy vs. Chemotherapy: unstratified OS HR was 0.69 (95% CI: 0.56, 0.84) for PD-L1 CPS ≥1 subgroup and 0.98 (95% CI: 0.50, 1.95) for PD-L1 CPS <1 subgroup.
• Intravenous Nivolumab with Ipilimumab vs. Chemotherapy: unstratified OS HR was 0.76 (95% CI: 0.62, 0.93) for PD-L1 CPS ≥1 subgroup and 1.0 (95% CI: 0.52, 1.94) for PD-L1 CPS <1 subgroup.

Previously Treated Unresectable Advanced, Recurrent Or Metastatic ESCC

The effectiveness of OPDIVO QVANTIG has been established for the treatment of unresectable advanced, recurrent, or metastatic ESCC after prior fluoropyrimidine- and platinum-based chemotherapy. Use of OPDIVO QVANTIG for this indication is supported by evidence from an adequate and well-controlled study conducted with intravenous nivolumab, and additional pharmacokinetic and safety data that demonstrated comparable pharmacokinetics and safety profiles between OPDIVO QVANTIG and intravenous nivolumab [see ADVERSE REACTIONS and CLINICAL PHARMACOLOGY]. Below is a description of the efficacy results of the adequate and well-controlled study of intravenous nivolumab in this ESCC population.

ATTRACTION-3

ATTRACTION-3 (NCT02569242) was a multicenter, randomized (1:1), active-controlled, open-label trial in patients with unresectable advanced, recurrent, or metastatic ESCC, who were refractory or intolerant to at least one fluoropyrimidine- and platinum-based regimen. The trial enrolled patients regardless of PD-L1 status, but tumor specimens were evaluated prospectively using the PD-L1 IHC 28-8 pharmDx assay at a central laboratory. The trial excluded patients who were refractory or intolerant to taxane therapy, had brain metastases that were symptomatic or required treatment, had autoimmune disease, used systemic corticosteroids or immunosuppressants, or had apparent tumor invasion of organs adjacent to the esophageal tumor or had stents in the esophagus or respiratory tract. Patients were randomized to receive nivolumab 240 mg by intravenous infusion over 30 minutes every 2 weeks or investigator’s choice of taxane chemotherapy consisting of docetaxel (75 mg/m² intravenously every 3 weeks) or paclitaxel (100 mg/m² intravenously once a week for 6 weeks followed by 1 week off).

Randomization was stratified by region (Japan vs. Rest of World), number of organs with metastases (≤1 vs. ≥2), and PD-L1 status (≥1% vs. <1% or indeterminate). Patients were treated until disease progression, assessed by the investigator per RECIST v1.1, or unacceptable toxicity. The tumor assessments were conducted every 6 weeks for 1 year, and every 12 weeks thereafter. The major efficacy outcome measure was OS. Additional efficacy outcome measures were ORR and PFS as assessed by the investigator using RECIST v1.1 and DOR.

A total of 419 patients were randomized; 210 to the intravenous nivolumab arm and 209 to the investigator’s choice arm (docetaxel: 31%, paclitaxel: 69%). The trial population characteristics were: median age 65 years (range: 33 to 87), 53% were ≥65 years of age, 87% were male, 96% were Asian and 4% were White. Sixty-seven percent of patients had received one prior systemic therapy regimen and 26% had received two prior systemic therapy regimens prior to enrolling in ATTRACTION-3. Baseline ECOG performance status was 0 (50%) or 1 (50%).

ATTRACTION-3 demonstrated a statistically significant improvement in OS for patients randomized to intravenous nivolumab as compared with investigator’s choice of taxane chemotherapy. OS benefit was observed regardless of PD-L1 expression level. The minimum follow-up was 17.6 months. Efficacy results are shown in Table 65 and Figure 23.

Figure 23: Overall Survival - ATTRACTION-3

Of the 419 patients, 48% had PD-L1 positive ESCC, defined as ≥1% of tumor cells expressing PD-L1. The remaining 52% had PD-L1 negative ESCC defined as <1% of tumor cells expressing PD-L1.

In a pre-specified exploratory analysis by PD-L1 status, the hazard ratio (HR) for OS was 0.69 (95% CI: 0.51, 0.94) with median survivals of 10.9 and 8.1 months for the intravenous nivolumab and investigator’s choice arms, respectively, in the PD-L1 positive subgroup. In the PD-L1 negative subgroup, the HR for OS was 0.84 (95% CI: 0.62, 1.14) with median survivals of 10.9 and 9.3 months for the intravenous nivolumab and investigator’s choice arms, respectively.

Gastric Cancer, Gastroesophageal Junction Cancer, And Esophageal Adenocarcinoma

The effectiveness of OPDIVO QVANTIG in combination with fluoropyrimidine- and platinum-containing chemotherapy has been established for the treatment of gastric cancer, gastroesophageal junction cancer, and esophageal adenocarcinoma. Use of OPDIVO QVANTIG for this indication is supported by evidence from an adequate and wellcontrolled study conducted with intravenous nivolumab, and additional pharmacokinetic and safety data that demonstrated comparable pharmacokinetics and safety profiles between OPDIVO QVANTIG and intravenous nivolumab [see ADVERSE REACTIONS and CLINICAL PHARMACOLOGY]. Below is a description of the efficacy results of the adequate and well-controlled study of intravenous nivolumab in this population.

CHECKMATE-649

CHECKMATE-649 (NCT02872116) was a randomized, multicenter, open-label trial in patients (n=1581) with previously untreated advanced or metastatic gastric cancer, gastroesophageal junction cancer, and esophageal adenocarcinoma. The trial enrolled patients regardless of PD-L1 status, and tumor specimens were evaluated prospectively using the PD-L1 IHC 28-8 pharmDx assay at a central laboratory. The trial excluded patients who were known human epidermal growth factor receptor 2 (HER2) positive, or had untreated CNS metastases. Patients were randomized to receive intravenous nivolumab in combination with chemotherapy (n=789) or chemotherapy (n=792). Patients received one of the following treatments:

• Intravenous nivolumab 240 mg in combination with mFOLFOX6 (fluorouracil, leucovorin and oxaliplatin) every 2 weeks or mFOLFOX6 every 2 weeks.
• Intravenous nivolumab 360 mg in combination with CapeOX (capecitabine and oxaliplatin) every 3 weeks or CapeOX every 3 weeks.

Patients were treated until disease progression, unacceptable toxicity, or up to 2 years. In patients who received intravenous nivolumab in combination with chemotherapy and in whom chemotherapy was discontinued, intravenous nivolumab monotherapy was allowed to be given at 240 mg every 2 weeks, 360 mg every 3 weeks, or 480 mg every 4 weeks up to 2 years after treatment initiation.

Randomization was stratified by tumor cell PD-L1 status (≥1% vs. <1% or indeterminate), region (Asia vs. US vs. Rest of World), ECOG performance status (0 vs. 1), and chemotherapy regimen (mFOLFOX6 vs. CapeOX). The major efficacy outcome measures, assessed in patients with PD-L1 CPS ≥5, were PFS assessed by BICR and OS. Additional efficacy outcome measures included OS and PFS in patients with PD-L1 CPS ≥1 and in all randomized patients, and ORR and DOR as assessed by BICR in patients with PD-L1 CPS ≥1 and ≥5, and in all randomized patients. Tumor assessments were conducted per RECIST v1.1 every 6 weeks up to and including week 48, then every 12 weeks thereafter.

The trial population characteristics were: median age 61 years (range: 18 to 90), 39% were ≥65 years of age, 70% were male, 24% were Asian, and 69% were White, and 1% were Black. Baseline ECOG performance status was 0 (42%) or 1 (58%). Seventy percent of patients had adenocarcinoma tumors in the stomach, 16% in the gastroesophageal junction, and 13% in the esophagus.

CHECKMATE-649 demonstrated a statistically significant improvement in OS and PFS for patients with PD-L1 CPS ≥5. Statistically significant improvement in OS was also demonstrated for all randomized patients. The minimum follow-up was 12.1 months. Efficacy results are shown in Table 66 and Figures 24, 25, and 26.
