Alhemo

Medical Editor: John P. Cunha, DO, FACOEP Last updated on RxList: 1/6/2025

Drug Summary

What Is Alhemo?

Alhemo (concizumab-mtci) is a tissue factor pathway inhibitor (TFPI) antagonist indicated for routine prophylaxis to prevent or reduce the frequency of bleeding episodes in adult and pediatric patients 12 years of age and older with hemophilia A (congenital factor VIII deficiency) with FVIII inhibitors or hemophilia B (congenital factor IX deficiency) with FIX inhibitors.

What Are Side Effects of Alhemo?

Side effects of Alhemo include:

  • injection site reactions (redness, bleeding, bruising) and
  • hives.

Seek medical care or call 911 at once if you have the following serious side effects:

  • Serious eye symptoms such as sudden vision loss, blurred vision, tunnel vision, eye pain or swelling, or seeing halos around lights;
  • Serious heart symptoms such as fast, irregular, or pounding heartbeats; fluttering in your chest; shortness of breath; and sudden dizziness, lightheadedness, or passing out;
  • Severe headache, confusion, slurred speech, arm or leg weakness, trouble walking, loss of coordination, feeling unsteady, very stiff muscles, high fever, profuse sweating, or tremors.

This document does not contain all possible side effects and others may occur. Check with your physician for additional information about side effects.

Dosage for Alhemo

The recommended dosing regimen of Alhemo is:

  • Day 1: Loading dose of 1 mg/kg
  • Day 2: Once-daily dose of 0.2 mg/kg until individualization of maintenance dose

4 weeks after initiation of treatment: For dose optimization, measure concizumab-mtci plasma concentration by Concizumab Enzyme-Linked Immunosorbent Assay (ELISA) prior to administration of next scheduled dose.

Once the concizumab-mtci concentration result is available, individualize the maintenance dose of Alhemo no later than 8 weeks after initiation of treatment, based on the following concizumab-mtci plasma concentrations:

  • Less than 200 ng/mL: adjust to a once-daily dose of 0.25 mg/kg
  • 200 to 4,000 ng/mL: continue once-daily dose of 0.2 mg/kg
  • Greater than 4,000 ng/mL: adjust to a once-daily dose of 0.15 mg/kg

Alhemo In Children

The safety and effectiveness of Alhemo for hemophilia A and B with inhibitors have been established in pediatric patients aged 12 years and older.

The safety and effectiveness of Alhemo for hemophilia A and B with inhibitors have not been established in pediatric patients younger than 12 years of age.

What Drugs, Substances, or Supplements Interact with Alhemo?

Alhemo may interact with other medicines such as:

  • high and/or frequent doses of bypassing agents (e.g., rFVIIa or aPCC).

Tell your doctor all medications and supplements you use.

Alhemo During Pregnancy and Breastfeeding

Tell your doctor if you are pregnant or plan to become pregnant before using Alhemo; it may harm a fetus. Pregnancy testing is recommended for patients who can become pregnant. Patients who can become pregnant should use a highly effective form of contraception during treatment with Alhemo and for 7 weeks after ending treatment. Human IgGs are known to be excreted in breast milk during the first few days after birth, decreasing to low concentrations soon afterwards; consequently, a risk to the breast-fed infant cannot be excluded during this short period. Afterwards, Alhemo could be used during breastfeeding if clinically needed. Consult your doctor before breastfeeding.

Additional Information

Our Alhemo (concizumab-mtci) Injection, for Subcutaneous Use Side Effects Drug Center provides a comprehensive view of available drug information on the potential side effects when taking this medication.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

Description for Alhemo

Concizumab-mtci, is a humanized IgG4 monoclonal antibody produced by recombinant DNA technology in Chinese Hamster Ovary (CHO) cells with an approximate molecular weight of 149 kDa.

Alhemo (concizumab-mtci) injection is a clear to slightly opalescent, and colorless to slightly yellow solution that may contain translucent to white particles. Alhemo is supplied as a single-patient-use prefilled pen for subcutaneous injection.

Each 1 mL of Alhemo single-patient-use prefilled pen (60 mg/1.5 mL) contains 40 mg active ingredient concizumab-mtci. Each 1 mL of Alhemo single-patient-use prefilled pen (150 mg/1.5 mL) contains 100 mg active ingredient concizumab-mtci. Each 1 mL of Alhemo single-patient-use prefilled pen (300 mg/3 mL) contains 100 mg active ingredient concizumab-mtci.

Each 1 mL of Alhemo single-patient-use prefilled pen contains the following excipients: arginine hydrochloride (5.27 mg), histidine (5.12 mg), phenol (3.5 mg), polysorbate 80 (0.25 mg), sodium chloride (1.46 mg), sucrose (51.3 mg), and water for injection.

Hydrochloric acid and sodium hydroxide may be added to adjust the pH to 6.0.

Uses for Alhemo

Alhemo is indicated for routine prophylaxis to prevent or reduce the frequency of bleeding episodes in adult and pediatric patients 12 years of age and older with:

  • hemophilia A (congenital factor VIII deficiency) with FVIII inhibitors
  • hemophilia B (congenital factor IX deficiency) with FIX inhibitors

Dosage for Alhemo

Recommended Dosage

For subcutaneous use only.

Alhemo should be administered once-daily. Avoid missed doses.

Recommended Dosing Regimen:
  • Day 1: Loading dose of 1 mg/kg
  • Day 2: Once-daily dose of 0.2 mg/kg until individualization of maintenance dose (see below)
    • 4 weeks after initiation of treatment: For dose optimization measure concizumab-mtci plasma concentration by Concizumab Enzyme-Linked Immunosorbent Assay (ELISA) prior to administration of next scheduled dose. An FDA-authorized test for the measurement of concizumab-mtci concentration in plasma is not currently available.
  • Once the concizumab-mtci concentration result is available, individualize the maintenance dose of Alhemo. no later than 8 weeks after initiation of treatment, based on the following concizumab-mtci- plasma concentrations:
    • Less than 200 ng/mL: adjust to a once-daily dose of 0.25 mg/kg
    • 200 to 4,000 ng/mL: continue once-daily dose of 0.2 mg/kg
    • Greater than 4,000 ng/mL: adjust to a once-daily dose of 0.15 mg/kg

The calculated dose is rounded off to the nearest injectable dose as follows:

  • 60 mg/1.5 mL (40 mg/mL) in increments of 0.4 mg (brown label)
  • 150 mg/1.5 mL (100 mg/mL) in increments of 1 mg (gold label)
  • 300 mg/3 mL (100 mg/mL) in increments of 1 mg (white label)

Additional measurements of concizumab-mtci plasma concentration should be taken at routine clinical follow-ups provided the patient has been on the same maintenance dose for 8 weeks of treatment to ensure steady-state plasma concentration. Maintenance of concizumab plasma concentration above 200 ng/mL is important to decrease the risk of bleeding episodes. If concizumab-mtci plasma concentration remains below 200 ng/mL at two consecutive measurements, the benefits of continued Alhemo treatment should be evaluated versus the potential risk of bleeding events, and alternative therapies if available should be considered.

As Alhemo is dosed by body weight (mg/kg), it is important to recalculate the dose when patients experience body weight changes.

Missed Dose

Adherence to daily dosing of Alhemo is important to maintain protection againsst bleeding. This is especially important during the initial 4 weeks of treatment to ensure a correct maintenance dose is established. Patients who miss a dose during the initial 4-week period should inform their healthcare professional and resume once-daily dosing at the initial 0.2 mg/kg dose level.

Missed Doses Once The Maintenance Dose Has Been Established

The following dosing guidelines should apply ONLY when a patient has forgotten to or neglected to take their once-daily maintenance dose:

  • 1 missed dose: Resume once-daily treatment at the maintenance dose level
  • 2 to 6 missed doses: Resume treatment with a double dose followed by once-daily treatment at the maintenance dose level
  • 7 or more missed doses: Physician should be contacted, and a new loading dose should be considered [see Recommended Dosage]
Management Of Breakthrough Bleeds

No dose adjustment of Alhemo is required in the case of breakthrough bleeds.

Management In The Perioperative Setting

No dose adjustment of Alhemo is required in the case of minor surgeries.

As there is limited experience in the perioperative setting, it is generally recommended to pause Alhemo at least 4 days prior to major surgery. Alhemo therapy can be resumed 10–14 days after surgery on the same maintenance dose without a new loading dose, considering the overall clinical picture of the patient. If necessary, consult a physician experienced in surgery of patients with bleeding disorders.

Immune Tolerance Induction

The safety and efficacy of concomitant use of Alhemo in patients receiving ongoing Immune Tolerance Induction (ITI), a desensitization strategy for the eradication of inhibitors, have not been established, and no data are available. Careful assessment of the potential benefits and risks should be performed if continuation or initiation of Alhemo during ITI is considered.

Changing To Alhemo From Other Hemostatic Products

  • Discontinue treatment with rFVIIa at least 12 hours before starting Alhemo.
  • Discontinue treatment with activated prothrombin complex concentrate (aPCC) at least 48 hours before starting Alhemo.
  • Discontinue prophylactic use of standard half-life factor VIII (FVIII) or factor IX (FIX) at least 24 hours before starting Alhemo.
  • When changing from other products to Alhemo, the half-life of the previous product should be considered.

Healthcare providers should discuss with patients receiving Alhemo and/or their caregivers the dose and schedule of bypassing agents or FVIII or FIX, if required, while receiving Alhemo prophylaxis.

Instructions And Dosage Modification For Bypassing Agents For Breakthrough Bleeding

Treatment with all bypassing agents (e.g., rFVIIa or aPCC) can be used for breakthrough bleeds, and the dose and duration will depend on the location and severity of the bleed.

For mild and moderate bleeds that require additional treatment with bypassing agents (e.g., rFVIIa or aPCC), the lowest-approved dose and the dose interval in the approved product labeling is recommended. For aPCC, a maximum dose of 100 units/kg body weight within 24 hours is recommended.

For severe bleeds, follow the dosing instructions provided in the approved labeling for the specific product based on clinical judgement.

Administration And Use Instructions

Treatment is intended for use under the guidance of a healthcare provider. Treatment should be initiated in a non-bleeding state. Alhemo may be self-administered or administered by a caregiver after appropriate training and reading the Instructions for Use, if a healthcare provider determines that is appropriate.

Administer Alhemo by subcutaneous injection to the abdomen or thigh with rotation of injection site every day. Subcutaneous injections should not be given in areas where the skin is tender, bruised, red or hard, or areas where there are moles, scars, or stretch marks. Children and lean patients should be instructed to use injection techniques that minimize risk of intramuscular injection, e.g. injecting into a pinched fold of skin.

Always use a new needle for each injection.

Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Alhemo is a clear to slightly opalescent and colorless to slightly yellow solution that may contain translucent to white particles. Do not use if the solution is discolored.

Each Alhemo prefilled pen is for use by a single patient. An Alhemo pen must not be shared between patients, even if the needle is changed.

Alhemo is recommended to be used with NovoFine® or NovoFine® Plus needles with a gauge of 32 and a length of 4 mm. If needles longer than 4 mm are used, injection techniques that minimize the risk of intramuscular injection should be used.

Instructions for delivering the dosage are provided in the Instructions for Use leaflet enclosed with each Alhemo single-patient-use prefilled pen.

Side Effects for Alhemo

The following clinically significant adverse reactions are discussed in greater detail in other sections of the labeling:

  • Thromboembolic Events [see WARNINGS AND PRECAUTIONS]
  • Hypersensitivity Reactions [see WARNINGS AND PRECAUTIONS]
  • Increased Laboratory Values of Fibrin D-dimer and Prothrombin Fragment 1+2 [see WARNINGS AND PRECAUTIONS]

Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in clinical trials of another drug and may not reflect the rates observed in clinical practice.

The data in the WARNINGS AND PRECAUTIONS reflect exposure to Alhemo based on pooled data from clinical trials explorer3 (phase 1b), explorer4 (phase 2), explorer5 (phase 2), explorer7 (phase 3) and explorer8 (phase 3), in which a total of 320 male patients with hemophilia A with and without inhibitors and hemophilia B with and without inhibitors received at least one dose of Alhemo as routine prophylaxis. The patients were exposed for a total of 475 exposure years.

Patients With HAwI (Hemophilia A With Inhibitors) And HBwI (Hemophilia B With Inhibitors)

The data described below reflect exposure of 52 patients with HAwI and HBwI who were previously treated on-demand therapy and who were randomized in explorer7 to arm 1 to receive on- demand treatment with bypassing agents (n = 19) or arm 2 to receive Alhemo prophylaxis (n = 33) at the recommended dosing regimen [see Clinical Studies]. The median duration of treatment was 31.1 weeks (range 3.9, 72.9 weeks) in arm 1 (on- demand arm) and 40.1 weeks (range 3.1, 56.3 weeks) in arm 2 (Alhemo prophylaxis).

Serious adverse reactions were reported in 6.1% of patients who received Alhemo. These serious adverse reactions were renal infarct and hypersensitivity reaction. Permanent discontinuation of Alhemo due to an adverse reaction occurred in 1 patient due to a renal infarct. Dosage interruptions of Alhemo due to an adverse reaction occurred in 1 patient (3%) and was a hypersensitivity reaction. The most common adverse reactions (≥5%) were injection site reactions and urticaria (see Table 1).

Drug Interactions for Alhemo

Bypassing Agents

Take appropriate precautions when treating break-through bleeding events in hemophilia patients receiving Alhemo prophylaxis and a bypassing agent [see DOSAGE AND ADMINISTRATION]. For mild and moderate bleeds that require additional treatment with bypassing agents (e.g., rFVIIa or aPCC), the lowest-approved dose in the approved product labeling is recommended. For aPCC, a maximum dose of 100 units/kg body weight within 24 hours is recommended. For severe bleeds, follow the dosing instructions provided in the approved labeling for the specific product based on clinical judgement.

Additive and sometimes synergistic increase in thrombin peak as quantified in the thrombin generation assay has been observed in plasma from hemophilia patients who were on prophylactic treatment with concizumab-mtci with concomitant presence of rFVIII, rFIX or bypassing agents including rFVIIa and aPCC [see CLINICAL PHARMACOLOGY].

Warnings for Alhemo

Included as part of the "PRECAUTIONS" Section

Precautions for Alhemo

Thromboembolic Events

Venous and arterial thromboembolic events were reported in 1.3% of patients (4/320) in Alhemo clinical trials. These cases occurred in patients with multiple risk factors for thromboembolism, including the use of high doses or prolonged treatment with factor product or bypassing agent (2 of 4 events).

Risk factors for thromboembolism may include the use of high and/or frequent doses of breakthrough bleed treatments (factor products or bypassing agents) or conditions in which tissue factor is overexpressed (e.g., atherosclerotic disease, crush injury, cancer, disseminated intravascular coagulation, thrombotic microangiopathy, or septicemia).

Inform Alhemo treated patients of signs and symptoms of thromboembolic events. Monitor patients for thromboembolic events. In case of suspicion of thromboembolic events, discontinue Alhemo and initiate further investigations and management strategies.

Hypersensitivity Reactions

Alhemo is contraindicated in patients with a history of known serious hypersensitivity to Alhemo or its components or the inactive ingredients. Hypersensitivity reactions including erythema, rash, pruritus, and abdominal pain have occurred in Alhemo treated patients. One patient (less than 1% of patients treated in the clinical studies) experienced anaphylaxis which resolved after treatment with antihistamines and corticosteroids. Instruct patients of the signs of acute hypersensitivity reactions. Instruct patients to contact their healthcare provider for mild reactions and to seek urgent medical attention for moderate to severe reactions. Discontinue Alhemo if severe hypersensitivity symptoms occur, and initiate medical management.

Increased Laboratory Values Of Fibrin D-dimer And Prothrombin Fragment 1+2

Increased levels of fibrin D-dimer and increased levels of prothrombin fragment 1.2 were seen in 29 (9.1%) and 18 (5.6%) of patients, respectively. The plasma concentration of concizumab-mtci is positively correlated with fibrin D-dimer and prothrombin fragments 1.2 indicating a hemostatic effect of concizumab-mtci. For patients taking Alhemo, these coagulation biomarkers may not be reliable predictive markers for clinical decision-making with suspicion of thrombosis such as deep vein thrombosis (DVT) and pulmonary embolism (PE).

Patient Counseling Information

Advise the patient to read the FDA-approved patient labeling (Medication Guide and Instructions for Use).

  • Thromboembolic events: Inform patients of the signs and symptoms of thromboembolic events, including swelling, warmth, pain, or redness of the skin (and that these could be symptoms of a blood clot in the legs or arms); shortness of breath or severe chest pain (and that these could be symptoms of blood clots in the chest [heart and lungs]).; headache, confusion, difficulty with speech or movement, numbness of the face, eye pain or swelling, or vision problems (and that these could be symptoms of a blood clot in the brain or eyes); or sudden pain in the stomach or lumbar area (and that these could be symptoms of blood clots in the gut or kidneys). Advise patients to contact their healthcare provider for mild reactions and to seek urgent medical attention for moderate to severe reactions [see WARNINGS AND PRECAUTIONS].
    • In conditions in which tissue factor is overexpressed (e.g., advanced atherosclerotic disease, crush injury, cancer, or septicemia), there may be a risk of thromboembolic events or disseminated intravascular coagulation (DIC) with Alhemo treatment.
  • Hypersensitivity: Inform patients of the early signs of hypersensitivity reactions, including rash, redness, hives, and itching, facial swelling, tightness of the chest, and wheezing as well the signs of an anaphylactic reaction such as itching on large areas of skin; redness and/or swelling of lips, tongue, face, or hands; difficulty swallowing; shortness of breath; wheezing; tightness of the chest; pale and cold skin; fast heartbeat; or dizziness/low blood pressure. Advise patients to discontinue use of Alhemo immediately and contact their healthcare provider if any signs or symptoms occur [see WARNINGS AND PRECAUTIONS].

Advise patients on the importance of adherence to daily dosing and to speak with their healthcare provider before discontinuing treatment with Alhemo as patients who are not adhering to daily dosing or stop treatment with Alhemo may no longer be protected against bleeding.

Advise patients to follow the recommendations regarding proper sharps disposal provided in the FDA-approved Instructions for Use.

Nonclinical Toxicology

Carcinogenesis, Mutagenesis, Impairment Of Fertility

No long-term animal studies have been conducted to evaluate the carcinogenic potential of concizumab-mtci nor have studies been performed to determine the effects of concizumab-mtci on genotoxicity.

In a 26-week toxicity study in sexually mature male and female cynomolgus monkeys with subcutaneous doses up to 9 mg/kg/day (corresponding to 3400-fold the human exposure, based on AUC0 to 24h), concizumab-mtci did not affect fertility (testicular size, sperm functionality or menstrual cycle duration) and did not cause any changes in the male or female reproductive organs.

Use In Specific Populations

Pregnancy

Risk Summary

Based on its mechanism of action, Alhemo may cause fetal harm when administered to a pregnant woman [see CLINICAL PHARMACOLOGY]. There are no available data on Alhemo use in pregnant women to evaluate for a drug-associated risk of major birth defects, miscarriage or other adverse maternal or fetal outcomes. Animal reproduction studies have not been conducted with Alhemo. Although there are no data on concizumab-mtci, monoclonal antibodies can be actively transported across the placenta, and concizumab-mtci may cause fetal harm. It is unknown whether Alhemo can affect reproductive capacity. Alhemo should only be used during pregnancy if the potential benefit for the mother outweighs the potential risk to the fetus.

The estimated background risk of birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defect and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively.

Lactation

Risk Summary

There is no information regarding the presence of Alhemo in either human or animal milk, the effect on the breastfed child, or the effects on milk production.

Clinical Considerations

Human IgGs are known to be excreted in breast milk during the first few days after birth, decreasing to low concentrations soon afterwards; consequently, a risk to the breast-fed infant cannot be excluded during this short period. Afterwards, Alhemo could be used during breast-feeding if clinically needed.

Females And Males Of Reproductive Potential

Pregnancy Testing

Pregnancy testing is recommended for females of reproductive potential.

Contraception

Women of childbearing potential should use a highly effective form of contraception during treatment with Alhemo and for 7 weeks after ending treatment. The benefits and thromboembolic risks of the type of contraceptives used should be evaluated by the treating physician.

Pediatric Use

The safety and effectiveness of Alhemo for hemophilia A and B with inhibitors have been established in pediatric patients aged 12 years and older. Use of Alhemo for this indication is supported by evidence from adequate and well-controlled studies in adult and pediatric patients aged 12 years and older [see ADVERSE REACTIONS and Clinical Studies]. The safety and effectiveness of Alhemo for hemophilia A and B with inhibitors have not been established in pediatric patients younger than 12 years of age.

Geriatric Use

Clinical studies of Alhemo did not include sufficient numbers of patients 65 years of age and older to determine whether they respond differently from younger adult patients.

Increased Body Weight

The apparent clearance and volume of distribution of concizumab-mtci decreased with increasing body weight [see CLINICAL PHARMACOLOGY]. However, patients should receive the approved recommended Alhemo dosage titration and concizumab-mtci plasma concentration monitoring regardless of body weight [see DOSAGE AND ADMINISTRATION].

Overdose Information for Alhemo

No Information Provided

Contraindications for Alhemo

Alhemo is contraindicated in patients with a history of known serious hypersensitivity to Alhemo or its components or the inactive ingredients [see WARNINGS AND PRECAUTIONS and DESCRIPTION].

Clinical Pharmacology for Alhemo

Mechanism Of Action

Concizumab-mtci is a monoclonal antibody antagonist of endogenous Tissue Factor Pathway Inhibitor (TFPI). Through the inhibition of TFPI, concizumab-mtci acts to enhance FXa production during the initiation phase of coagulation which leads to improved thrombin generation and clot formation with the goal of achieving hemostasis in patients with Hemophilia A or B with inhibitors. The effect of concizumab-mtci is not influenced by the presence of inhibitory antibodies to FVIII or FIX. There is no structural relationship or sequence homology between concizumab-mtci and FVIII or FIX and, as such, treatment with concizumab-mtci does not induce or enhance the development of direct inhibitors to FVIII or FIX.

Pharmacodynamics

Increasing concizumab-mtci dose levels resulted in decreased levels of free TFPI (plasma TFPI not bound to concizumab-mtci) and increased duration of free TFPI suppression. Free TFPI plasma levels pre-dose decreased from a geometric mean (CV%) of 88.3 (20%) ng/mL at baseline to 10.7 (105%) ng/mL at week 24 in patients on Alhemo prophylaxis, while the geometric mean (CV%) was 76.0 (18%) ng/mL at week 24 for patients on no Alhemo prophylaxis. Mean thrombin peak within the range of normal plasma reflected that concizumab-mtci re–established thrombin generation capacity.

Drug Interaction

In Vitro Studies

Additive and sometimes synergistic increase in thrombin peak as quantified in the thrombin generation assay has been observed in plasma from hemophilia patients who were on prophylactic treatment with concizumab-mtci with concomitant presence of rFVIII, rFIX or bypassing agents including rFVIIa and aPCC. Depending on concentrations of concizumab-mtci and hemostatic agents, the impact on thrombin peak ranged from being additive with all hemostatic agents to an extra 40% effect with rFVIIa, an extra 33% effect with aPCC, an extra 22% with rFVIII and less than 13% with rFIX.

Pharmacokinetics

Peak and trough geometric mean plasma concizumab-mtci concentrations at steady state are shown in Table 2. Following a single Alhemo loading dose of 1 mg/kg, the steady state concentrations were reached around Day 4 and remained within a stable exposure range with daily maintenance doses. Concizumab-mtci AUC and Cmax increased with increasing dose in a greater than doseproportional manner following subcutaneous administration.

Absorption

Concizumab-mtci time to maximum plasma concentration ranged from 8 hours to 99 hours (4.1 days) following a single Alhemo subcutaneous dose of 0.05 to 3 mg/kg in healthy and hemophilia subjects.

Distribution

Concizumab-mtci volume of distribution for a typical 70 kg patient is about 3 L.

Elimination

Concizumab-mtci is cleared via linear and non-linear mechanisms. Concizumab-mtci exhibited non-linear pharmacokinetics due to target-mediated drug disposition (TMDD) which occurs when it forms concizumab-mtci/TFPI complex. Once the target becomes saturated, linear pathway (i.e., catabolism) dominates.

Based on population pharmacokinetic analysis, 90% of concizumab-mtci is expected to be eliminated by the end of approximately 4 days after the last dose (time for 50% of drug to be eliminated is approximately 1 day).

Metabolism

Concizumab-mtci is expected to be metabolized into small peptides by catabolic pathways.

Specific Populations

No clinically significant differences in the pharmacokinetics of concizumab-mtci were observed based on age (12 year to 79 years), race (White 62.9%, Asian 25.0%, Black 6.0%), hemophilia type (A vs B). No dedicated studies have been conducted to evaluate the impact of renal or hepatic impairment. As concizumab-mtci is a monoclonal antibody, there is no expectation for concizumab-mtci exposures to be different in patients with renal or hepatic impairment.

Body Weight

The apparent clearance and volume of distribution of concizumab-mtci increased with increasing body weight (27 kg to 130.7 kg) [see Use In Specific Populations].

Immunogenicity

The observed incidence of anti-drug antibodies is highly dependent on the sensitivity and the specificity of the assay. Differences in assay methods preclude meaningful comparisons of the incidence of anti-drug antibodies (ADA) in the studies described below with the incidence of ADA in other studies, including those of concizumab-mtci or of other concizumab products.

During the treatment period in 4 trials with a duration of 11 weeks, ≥76 weeks, ≥76 weeks, and ≥32 weeks, 47 out of the 185 treated patients (25.4%) developed anti-concizumab-mtci antibodies. Among the 47 patients who tested positive for ADA, 12 patients (25.5%) developed neutralizing antibodies (NAbs) against concizumab-mtci. In 1 patient who developed NAb against concizumabmtci, free TFPI levels were restored to baseline indicative of effectiveness likely being compromised. In the remaining 46 patients, there was no identified clinically significant effect of the antibodies on pharmacokinetics, pharmacodynamics, safety, or effectiveness of concizumab-mtci.

Interference Of Concizumab-Mtci With Laboratory Tests

In Vitro Studies

No clinically significant interference with standard prothrombin and activated partial thromboplastin time assays or FVIII or FIX activity measurement using clot and chromogenic assays was observed with concizumab-mtci. Further, no clinically relevant interference with assays for inhibitory antibodies to FVIII or FIX (Bethesda assay) was observed with concizumab-mtci.

Animal Toxicology And/Or Pharmacology

Pharmacology mediated formation of thrombi manifested in cynomolgus monkeys dosed subcutaneously during toxicology studies of 13-weeks (≥ 10 mg/kg/day), 26-weeks (≥ 3 mg/kg/day) and 52-weeks (≥ 1 mg/kg/day) in duration corresponding to ≥ 3732-fold, ≥ 955- fold and ≥ 308-fold, respectively, the human clinical exposure based on AUC0 to 24h in patients with Hemophilia A or B at the MRHD.

In a 28-day drug-drug interaction toxicity study in cynomolgus monkey with daily dosing of 1 mg/kg concizumab-mtci to achieve steady state, three consecutive intravenous doses of up to 1 mg/kg rFVIIa were administered with 2-hour intervals to the concizumab-mtci dosed animals. No adverse findings were observed at a concizumab-mtci exposure corresponding to 205-fold the human exposure, based on AUC0 to 24h.

The efficacy of Alhemo in patients with hemophilia A and B with inhibitors was evaluated in the explorer7 trial (NCT04083781), a multi-national, multi-center, open-label, phase 3 trial that investigated the safety and efficacy of Alhemo for routine prophylaxis in 91 adults (58 HAwI and 33 HBwI) and 42 adolescents (22 HAwI and 20 HBwI) male patients with hemophilia A or B with inhibitors who have been prescribed, or are in need of, treatment with bypassing agents. Eptacog alfa was the rFVIIa used in explorer7. Patients were excluded if they had a history, current signs or symptoms, or at high risk of thromboembolic events, ongoing or planned immune tolerance induction treatment, in addition to patients with planned major surgery.

Among the 133 patients treated with Alhemo in the trial the mean age was 29 years (range: 12 to 79); 42 patients were 12 to <18 years of age, 89 patients were 18 to 64 years of age, and 2 patients were ≥65 years of age, and all were male. Seventy-eight (78) patients were White, 37 patients were Asian, 9 patients were Black or African American, 6 patients had race information unreported, and 3 patients were American Indian or Alaska Native; 6 patients identified as Hispanic or Latino, 122 patients identified as not Hispanic or Latino and 5 patients had ethnicity information unreported.

The trial was comprised of 4 arms, two randomized arms and two non-randomized arms:

  • Arms 1 and 2: 52 patients (27 HAwI, and 25 HBwI), previously treated on-demand, were randomized 1:2 to no prophylaxis (arm 1: on demand treatment with bypassing agents) or Alhemo prophylaxis (arm 2), with stratification by hemophilia type (HAwI, HBwI) and prior 24-week bleeding rate (< 9 or ≥9)
  • Arms 3 and 4: 81 additional patients (53 HAwI and 28 HBwI) treated with Alhemo prophylaxis

Treatment with Alhemo included a loading dose of 1 mg/kg on the first day and a once-daily dose of 0.20 mg/kg starting on the second day. The dose was individualized to 0.25 mg/kg or 0.15 mg/kg if Alhemo plasma concentration measured once after 4 weeks of treatment was <200 ng/mL or >4000 ng/mL, respectively. Measurement of concizumab-mtci plasma concentration after 4 weeks was used to optimize the daily maintenance dose. In the trial, a total of 108 patients received their individualized dose, 1 patient on 0.15 mg/kg, 79 patients on 0.20 mg/kg and 28 patients on 0.25 mg/kg.

Efficacy was evaluated in hemophilia A and B patients with inhibitors when all patients in arms 1 and 2 had completed at least 24 or at least 32 weeks, respectively), by comparing the number of treated bleeding episodes between Alhemo prophylaxis (arm 2) and no prophylaxis (arm 1). Using a negative binomial model, a ratio of the annualized bleeding rates (ABR) was estimated to 0.14 (p<0.001), corresponding to a reduction in ABR of 86% for subjects on Alhemo prophylaxis compared to no prophylaxis. The estimated mean ABR was 1.7 [95%CI: 1.01; 2.87] for patients on Alhemo prophylaxis (arm 2) and 11.8 [95%CI: 7.03; 19.86] for patients on no prophylaxis (arm 1).

What is the most important information I should know about Alhemo?

  • It is important to follow the daily dosing schedule of Alhemo to stay protected against bleeding. This is especially important during the first 4 weeks of treatment to make sure a correct maintenance dose is established. Use Alhemo exactly as prescribed by your healthcare provider. Do not stop using Alhemo without talking to your healthcare provider. If you miss doses, or stop using Alhemo, you may no longer be protected against bleeding.
  • Your healthcare provider may prescribe bypassing agents during treatment with Alhemo. Carefully follow your healthcare provider’s instructions regarding when to use on-demand bypassing agents, and the recommended dose and schedule for breakthrough bleeds.

See “How should I use Alhemo?” for more information on how to use Alhemo.

What is Alhemo?

Alhemo is a prescription medicine used for routine prophylaxis to prevent or reduce the frequency of bleeding episodes in adults and children 12 years of age and older with hemophilia A with factor VIII inhibitors or hemophilia B with factor IX inhibitors.

It is not known if Alhemo is safe and effective in people using Alhemo while receiving ongoing Immune Tolerance Induction (ITI).

It is not known if Alhemo is safe and effective for hemophilia A and B with and without inhibitors in children younger than 12 years of age.

Do not use Alhemo if you are allergic to concizumab-mtci or any of the ingredients in Alhemo. See the end of this Medication Guide for a complete list of ingredients in Alhemo.

Before using Alhemo, tell your healthcare provider about all of your medical conditions, including if you:

  • have a planned surgery. Your healthcare provider may stop treatment with Alhemo before your surgery. Talk to your healthcare provider about when to stop using Alhemo and when to start it again if you have a planned surgery.
  • are pregnant or plan to become pregnant. It is not known if Alhemo may harm your unborn baby.
    Females who are able to become pregnant
    • Your healthcare provider may do a pregnancy test before you start treatment with Alhemo.
    • You should use an effective birth control (contraception) during treatment with Alhemo and for 7 weeks after ending treatment. Talk to your healthcare provider about birth control methods that you can use during this time.
  • are breastfeeding or plan to breastfeed. It is not known if Alhemo passes into your breast milk. Talk to your healthcare provider about the best way to feed your baby during treatment with Alhemo.

Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Know the medicines you take. Keep a list of them to show your healthcare provider and pharmacist when you get a new medicine.

How should I use Alhemo?

Read the Instructions for Use that comes with Alhemo for information about how to prepare and inject a dose of Alhemo, and how to properly throw away (dispose of) used Alhemo pens and needles.

  • Use Alhemo exactly as prescribed by your healthcare provider.
  • Your healthcare provider will provide instructions for stopping (discontinuing) your current treatment when switching to Alhemo.
  • Inject Alhemo 1 time a day.
  • Your healthcare provider should show you or your caregiver how to use Alhemo before you use it for the first time.
  • Alhemo is given as an injection under the skin (subcutaneous injection) by you or a caregiver.
  • Ask your healthcare provider if you need to use a different injection technique. For example, children and people who are lean may need to inject into a pinched fold of skin to avoid injecting too deep (into the muscle).
  • Change (rotate) your injection site with each injection. Do not use the same site for each injection.
  • You will inject a larger dose (a loading dose) of Alhemo on your first day of treatment. Then your healthcare provider will prescribe a dose to inject 1 time a day until your maintenance dose is established.
  • To determine the right maintenance dose for you, your healthcare provider will do a blood test to check the amount of Alhemo in your blood. Your healthcare provider may do additional blood tests during treatment with Alhemo.
  • Your healthcare provider will prescribe your dose based on your weight. If your weight changes, tell your healthcare provider.
  • Your healthcare provider will provide information on the treatment of breakthrough bleeding during your treatment with Alhemo.
  • Do not share your Alhemo pens and needles with another person, even if the needle has been changed. You may give another person an infection or get an infection from them.
  • If you miss a dose of Alhemo during the first 4 weeks of treatment, contact your healthcare provider right away. Your healthcare provider will tell you how much Alhemo to inject.
  • If you miss a dose of Alhemo after your daily maintenance dose is established:
    • For 1 missed dose, continue your normal daily dose.
    • For 2 to 6 missed doses, give 2 doses as soon as you remember. Then continue your normal daily dose the next day.
    • For 7 or more missed doses, contact your healthcare provider right away as you will need to receive a new loading dose before continuing your normal daily dose.
    • If you are unsure about how much to Alhemo to inject, contact your healthcare provider.

What are the possible side effects of Alhemo?

Alhemo may cause serious side effects, including:

  • Blood clots (thromboembolic events). Alhemo may cause blood clots to form in blood vessels, such as in your arms, legs, heart, lung, brain, eyes, kidneys, or stomach. You may be at risk for getting blood clots during treatment with Alhemo if you use high or frequent doses of factor products or bypassing agents to treat breakthrough bleeds, or if you have certain conditions. Get medical help right away if you have any signs and symptoms of blood clots, including:
    • swelling, warmth, pain, or redness of the skin
    • headache

Important information you need to know before injecting Alhemo

  • Use Alhemo exactly as prescribed by your healthcare provider.
  • Your Alhemo pen is for single-patient-use only. Do not share your Alhemo pen with other people, even if the needle has been changed. You may give other people a serious infection or get a serious infection from them.
  • Your healthcare provider should show you or your caregiver how to use Alhemo before you use it for the first time.
  • Ask your healthcare provider if you need to use a different injection technique. For example, children and people who are lean may need to inject into a pinched fold of skin to avoid injecting too deep (into the muscle).
  • After 28 days, you must throw away (discard) your pen in an FDA-cleared sharps disposal container even if some medicine is left in the pen.
  • The pen can deliver doses from 0.4 mg to 32 mg in one injection. If your dose is more than 32 mg, you need to inject multiple times.

Important information about needles

  • Needles can be used for 1 injection only. Always use a new needle for each injection.
  • Do not re-use needles as this reduces the risk of contamination, infection, leakage, blocked needles, and incorrect dosing.
  • Never share needles with others.
  • Alhemo is recommended to be used with NovoFine and NovoFine Plus 32G x 4 mm injection needles.
  • If you use needles longer than 4 mm, talk to your healthcare provider about how to perform your injection.
  • Talk to your healthcare provider or pharmacist for more information about needles for your Alhemo pen.
  • Do not use the needle if it is bent or damaged.

Troubleshooting if no stream appears when testing the flow (Step 3)

  • If no stream appears, repeat Step 3 up to 6 times until you see a stream.
  • If still no stream appears, prepare a new needle (Step 2) and test again (Step 3).
  • If still no stream appears after attaching a new needle, do not use the pen. Use a new pen or call Novo Nordisk at 1-844-668-6732 for help.

How much Alhemo is left in your pen?

The pen scale shows about how much Alhemo is left in your pen. In the example below, 24 milligrams (mg) is remaining in the pen.

The pen scale shows about how much Alhemo is left in your pen - Illustration

If you want to see more accurately how much Alhemo is left in your pen, turn the dose selector until it stops. The dose pointer will line up with the number of mg left in the pen.

If the dose counter shows 32 mg, at least 32 mg is left in the pen. If the dose counter shows less than 32 mg, the number shown in the dose counter is the number of mg left in your pen. In the example below, the dose counter shows 13.6 mg, so there is 13.6 mg of Alhemo left in the pen.

  • After 28 days, you must throw away (discard) your pen in an FDA-cleared sharps disposal container even if some medicine is left in the pen.
  • The pen can deliver doses from 1 mg to 80 mg in one injection. If your dose is more than 80 mg, you need to inject multiple times.

Important information about needles

  • Needles can be used for 1 injection only. Always use a new needle for each injection.
  • Do not re-use needles as this reduces the risk of contamination, infection, leakage, blocked needles, and incorrect dosing.
  • Never share needles with others.
  • Alhemo is recommended to be used with NovoFine and NovoFine Plus 32G x 4 mm injection needles.
  • If you use needles longer than 4 mm, talk to your healthcare provider about how to perform your injection.
  • Talk to your healthcare provider or pharmacist for more information about needles for your Alhemo pen.
  • Do not use the needle if it is bent or damaged.

Troubleshooting if no stream appears when testing the flow (Step 3)

  • If no stream appears, repeat Step 3 up to 6 times until you see a stream.
  • If still no stream appears, prepare a new needle (Step 2) and test again (Step 3).
  • If still no stream appears after attaching a new needle, do not use the pen. Use a new pen or call Novo Nordisk at 1-844-668-6732 for help.

How much Alhemo is left in your pen?

The pen scale shows about how much Alhemo is left in your pen. In the example below, 60 milligrams (mg) is remaining in the pen.

If you want to see more accurately how much Alhemo is left in your pen, turn the dose selector until it stops.

The dose pointer will line up with the number of mg left in the pen.

If the dose counter shows 80 mg, at least 80 mg is left in the pen. If the dose counter shows less than 80 mg, the number shown in the dose counter is the number of mg left in your pen. In the example below, the dose counter shows 34 mg, so there is 34 mg of Alhemo left in the pen.

Storing Alhemo

  • Before first use:
    • Store unused Alhemo pens in the refrigerator between 36°F to 46°F (2°C to 8°C).
  • After first use:
    • Store the Alhemo pen in the refrigerator between 36°F to 46°F (2°C to 8°C) or at room temperature no warmer than 86°F (30°C) for up to 28 days.
    • Write the date of first use in the space provided on the carton.
    • Throw away (discard) the Alhemo pen 28 days after first opening even if some medicine is left in the pen.
  • Store Alhemo with the cap on and keep it in the original carton to protect from light.
  • Do not store Alhemo in direct sunlight and keep away from direct heat.
  • When stored in the refrigerator, do not store the pen directly next to the cooling element (the part that cools the refrigerator).
  • Do not freeze Alhemo.
  • Do not use Alhemo if it has been frozen or if it has been stored above 86°F (30°C).

Keep Alhemo and all medicine out of the reach of children.

Throwing away (disposing of) Alhemo pens, needles, needle caps

  • Put your used pens, needles, and needle caps in an FDA-cleared sharps disposal container right away after use. Do not throw away (dispose of) loose needles and pens in your household trash.
  • If you do not have an FDA-cleared sharps disposal container, you may use a household container that is:
    • made of heavy-duty plastic,
    • can be closed with a tight-fitting, puncture-resistant lid, without sharps being able to come out,
    • upright and stable during use,
    • leak-resistant, and
    • properly labelled to warn of hazardous waste inside the container.
  • When your sharps disposal container is almost full, you will need to follow your community guidelines for the right way to dispose of your sharps disposal container. There may be state or local laws about how you should dispose of used needles and pens. For more information about safe sharps disposal, and for specific information about safe sharps disposal in the state that you live in, go to the FDA’s website at: http://www.fda.gov/safesharpsdisposal.
  • Do not dispose of your used sharps disposal container in your household trash unless your community guidelines permit this. Do not recycle your used sharps disposal container.
