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 the clinical trials of another drug and may not reflect the rates observed in practice.

The pooled safety population described in WARNINGS AND PRECAUTIONS and below reflects exposure to MODEYSO at the recommended weight-based dose taken until disease progression or unacceptable toxicity in 376 adult and pediatric patients with glioma across four open-label clinical studies (ONC006, ONC013, ONC014, and ONC018) [see Clinical Studies (14)].

Of the 376 patients who received MODEYSO, 35% were exposed for 6 months, and 17% were exposed for 1 year.

The median age was 23 years (range: 3 to 80): 30% were 2 to 11 years old, 11% were 12 to 17 years

old, 55% were 18 to 64 years old, and 3.7% were 65 years or older. Fifty-two percent (52%) were female; 74% White, 10% unknown race or race not reported, 9% Black or African American, 4% Asian, 2.9% other or multiple races; and 13% were of Hispanic or Latino ethnicity. Karnofsky/Lansky Performance Status (KPS/LPS) score was 80 to 100 in 66% of patients, 60 to 70 in 27%, and <60 in 7%.

Relevant disease characteristics included primary tumor locations in the midline (91%) and non-midline regions (9%); 33% had diffuse intrinsic pontine glioma (DIPG); 30% had multifocal disease; 79% had an H3 K27M mutation; 75% had recurrent disease.

Serious adverse reactions occurred in 33% of patients who received MODEYSO. Serious adverse reactions in >2% of patients included hydrocephalus (5%), vomiting (4.3%), headache (3.2%), seizure (2.4%), and muscular weakness (2.1%).

Drug Interactions for Modeyso

Effect of Other Drugs on MODEYSO

Table 6 describes drug interactions where concomitant use of another drug affects MODEYSO.

Table 6: Effect of Other Drugs on MODEYSO

Strong and Moderate CYP3A4 Inhibitors
Prevention or Management	• Avoid concomitant use of strong and moderate CYP3A4 inhibitors with MODEYSO.   • If concomitant use cannot be avoided for adults and pediatric patients who weigh at least 52.5 kg, reduce the MODEYSO dose as recommended [see Dosage and Administration (2.5)].
Mechanism and Clinical Effects	• Dordaviprone is a CYP3A4 substrate.   • Strong and moderate CYP3A4 inhibitors increase dordaviprone exposure [see Clinical Pharmacology (12.3)], which may increase the risk of MODEYSO-related adverse reactions [see Warnings and Precautions (5.2)].
Strong or Moderate CYP3A4 Inducers
Prevention or Management	• Avoid concomitant use of strong and moderate CYP3A4 inducers with MODEYSO.
Mechanism and Clinical Effects	• Dordaviprone is a CYP3A4 substrate.   • Strong and moderate CYP3A4 inducers decrease dordaviprone exposure [see Clinical Pharmacology (12.3)], which may reduce the anti-tumor activity of MODEYSO.

Drugs Known to Prolong QTc Interval

Table 7 describes drug interactions associated with QTc interval prolongation when used concomitantly with MODEYSO.

Table 7: Products that Prolong QTc Interval

Products that Prolong QTc Interval
Prevention or Management	• Avoid concomitant use of MODEYSO with products known to prolong the QTc interval.   • If concomitant use cannot be avoided, separate administration of MODEYSO and the QT-prolonging product [see Warnings and Precautions (5.2) and Clinical Pharmacology (12.2)].
Clinical Impact	• MODEYSO causes concentration dependent QTc interval prolongation [see Clinical Pharmacology (12.2)].   • Concomitant use of MODEYSO with other QT-prolonging products may increase the risk of QTc-associated arrhythmias [see Warnings and Precautions (5.2)].

Warnings for Modeyso

Included as part of the PRECAUTIONS section.

Precautions for Modeyso

Hypersensitivity

MODEYSO can cause severe hypersensitivity reactions.

In the pooled safety population [see Adverse Reactions (6.1)], Grade 3 hypersensitivity reactions occurred in 0.3% of patients receiving MODEYSO. Signs and symptoms of hypersensitivity may include rash, hives, fever, low blood pressure, wheezing, or swelling of the face or throat.

Inform patients about the signs and symptoms of hypersensitivity reactions and instruct them to seek immediate medical attention if symptoms occur.

If clinically significant hypersensitivity or anaphylaxis occur, immediately interrupt MODEYSO and initiate appropriate medical treatment and supportive care. Based on the severity of the adverse reaction, temporarily interrupt or permanently discontinue MODEYSO [see Dosage and Administration (2.4)].

QTc Interval Prolongation

MODEYSO causes a concentration-dependent QTc interval prolongation [see Clinical Pharmacology (12.2)], which can increase the risk for ventricular tachyarrhythmias (e.g., torsades de pointes) or sudden death.

In the pooled safety population [see Adverse Reactions (6.1)], of the 82 patients who underwent at least one post-baseline ECG assessment, 6% experienced an increase in QTc of >60 msec compared to baseline after receiving MODEYSO and 1.2% had an increase in QTc to >500 msec.

Monitor ECGs and electrolytes prior to starting MODEYSO and then periodically during treatment as clinically indicated.

Significant prolongation of the QT interval may occur when MODEYSO is taken concomitantly with other products that have a known potential to prolong the QT interval. Avoid concomitant use of MODEYSO with products known to prolong the QT interval. If concomitant use cannot be avoided, separate administration of MODEYSO and the QT-prolonging product [see Drug Interactions (7.2) and Clinical Pharmacology (12.2)].

Increase the frequency of monitoring when administering MODEYSO to patients taking other products that have a known potential to prolong the QT interval and in patients with congenital long QT syndrome, existing QTc prolongation, a history of ventricular arrhythmias, electrolyte abnormalities, heart failure, or who are taking strong or moderate CYP3A4 inhibitors. Interrupt or reduce the dose of MODEYSO in patients who develop QT prolongation, and permanently discontinue MODEYSO in patients with signs of life-threatening arrhythmias [see Dosage and Administration (2.4)].

Embryo-fetal Toxicity

Based on findings from animal studies and its mechanism of action, MODEYSO can cause fetal harm when administered to a pregnant woman. In embryo-fetal development studies, oral administration of dordaviprone to pregnant rats and rabbits during organogenesis caused embryo-fetal mortality, alterations to growth, and structural abnormalities at exposures below the human exposure at the highest recommended dose.

Advise pregnant women and females of reproductive potential of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with MODEYSO and for 1 month after the last dose. Advise male patients with female partners of reproductive potential to use effective contraception during treatment with MODEYSO and for 1 month after the last dose [see Use in Specific Populations (8.1, 8.3)].

NONCLINICAL TOXICOLOGY

Carcinogenesis, Mutagenesis, Impairment of Fertility

Carcinogenesis

Carcinogenicity studies with dordaviprone were not conducted.

Mutagenesis

Dordaviprone was not genotoxic in in vitro (Ames and micronucleus assay) and in vivo (mouse micronucleus) assays.

Impairment of Fertility

Dedicated fertility studies were not conducted with dordaviprone.

Animal Toxicology and/or Pharmacology

The nonclinical safety profile of dordaviprone reflects the on-target pharmacology and dopamine receptor inhibition. In repeat-dose toxicology studies of up 13 weeks in duration, weekly oral administration of dordaviprone to dogs caused central nervous system-related toxicities including whole body tremors, cranial tremors, seizures, excessive salivation, lateral recumbency, rigidity, paddling of limbs, overall rigid body, salivation, abnormal gait/stance, and twitching at doses resulting in less than or equal to 0.7 times the human exposure at the highest recommended dose based on AUC. In a 13-week repeat-dose toxicology study in rats, mammary gland hyperplasia occurred at doses resulting in 0.11 times the human exposure at the highest recommended dose based on AUC.

PATIENT COUNSELING INFORMATION

Advise the patient and caregiver to read the FDA-approved patient labeling (Patient Information and Instructions for Use).

Hypersensitivity

Advise patients that MODEYSO can cause hypersensitivity. Inform patients about the signs and symptoms of hypersensitivity reactions and instruct patients or caregivers to seek immediate medical attention if symptoms occur [see Warnings and Precautions (5.1)].

QTc Interval Prolongation

Advise patients that MODEYSO can cause QTc interval prolongation. Inform patients of the signs and symptoms of QTc prolongation and instruct patients or caregivers to seek immediate medical attention if symptoms occur [see Warnings and Precautions (5.2)].

Drug Interactions

Inform patients that MODEYSO may interact with some drugs. Advise patients to inform their healthcare provider about all medications they are taking, including prescription and over-the-counter drugs, vitamins, and herbal products. Additionally, patients should consult their healthcare provider before starting or stopping any prescription drug, nonprescription drug, or supplement [see Drug Interactions (7)].

Administration

Instruct patients and caregivers to read the Instructions for Use before taking MODEYSO, and each time the patient gets a refill as there may be new information they need to know.

Patients should take MODEYSO orally once weekly on an empty stomach (no food intake at least hour prior to or 3 hours after taking MODEYSO). Take the prescribed dose at the same time on the same day of the week [see Dosage and Administration (2.3) and Clinical Pharmacology (12.3)].

Instruct patients to swallow capsules whole. For patients unable to swallow capsules whole, instruct patients to open capsules and mix contents with approximately 15 to 30 mL of liquid (sports drink, apple juice, lemonade, or water). Instruct patients to drink the mixture. After drinking the mixture, instruct patients to add another 15 to 30 mL of the liquid to the container, swirl to dissolve any remaining medication, and then drink the remaining contents [see Dosage and Administration (2.3) and Instructions for Use].

Embryo-fetal Toxicity

Advise pregnant women and females of reproductive potential of the potential risk to a fetus.

Advise females to inform their healthcare provider of a known or suspected pregnancy [see Warnings and Precautions (5.3) and Use in Specific Populations (8.1, 8.3)].

Advise females of reproductive potential to use effective contraception during treatment with MODEYSO and for 1 month after the last dose [see Use in Specific Populations (8.3)].

Advise male patients with female partners of reproductive potential to use effective contraception during treatment with MODEYSO and for 1 month after the last dose [see Use in Specific Populations (8.3)].

Lactation

Advise women not to breastfeed during treatment with MODEYSO and for 1 week after the last dose [see Use in Specific Populations (8.2)].

Clinical Pharmacology for Modeyso

Mechanism of Action

Dordaviprone is a protease activator of the mitochondrial caseinolytic protease P (ClpP). Dordaviprone also inhibits the dopamine D2 receptor.

Diffuse midline gliomas harboring an H3 K27M mutation are associated with the loss of H3 K27 trimethylation. In-vitro, dordaviprone activated the integrated stress response, induced apoptosis, and altered mitochondrial metabolism leading to restored histone H3 K27 trimethylation in H3 K27M-mutant diffuse glioma models.

Dordaviprone exhibited antitumor activity in cell-based assays and in vivo models of H3 K27M-mutant diffuse glioma.

Pharmacodynamics

Cardiac Electrophysiology

At 1.2 times the maximum recommended dose, the estimated mean QTcF change was 11.8 msec (90% CI: 9.8, 13.7) [see Warnings and Precautions (5.2) and Drug Interactions (7.2)].

Pharmacodynamics

The exposure-response relationship and time course of pharmacodynamic response for the safety and effectiveness of dordaviprone have not been fully characterized.

Pharmacokinetics

Dordaviprone pharmacokinetics were predicted following a single dose in patients at the approved recommended dosage and are presented as mean (CV%) unless otherwise specified. Dordaviprone maximum concentration (C_max) is 2.8 mcg/mL (42%), and total systemic exposure (AUC) is

23 hr·mcg/mL (48%). Dordaviprone C_max and AUC increased in a dose proportional manner over the dose range of 125 to 625 mg. No accumulation is observed following once weekly dosing.

Absorption

Dordaviprone median (min, max) time to maximum plasma concentration (T_max) is 1.4 hours (0.5, 5.6 hours).

Food Effect

Dordaviprone C_max decreased by 40% with no change on AUC following administration with a high-fat meal (800 to 1,000 calories, 50% fat).

Distribution

Dordaviprone apparent (oral) volume of distribution is 450 L (40%).

Dordaviprone plasma protein binding is 95% to 97% and independent of concentrations in vitro. The median blood-to-plasma ratio is 0.67 in vitro.

Metabolism

Dordaviprone is primarily metabolized by CYP3A4 with minor contribution from CYP2B6, CYP2C8, CYP2C9, CYP2D6, and CYP3A5.

Excretion

Dordaviprone mean terminal half-life is 11 hours (30%), and the apparent clearance is approximately 27 L/hr (48%).

Following a single dose of radiolabeled dordaviprone, 70% of the dose was recovered in urine and 20% in feces with no notable unchanged dordaviprone in urine or feces.

Specific Populations

No clinically significant differences in the pharmacokinetics of dordaviprone were observed based on age (3 to 90 years), sex, race (74% White, 9% Black or African American, or 5% Asian) or mild hepatic impairment (total bilirubin ≤ULN with AST >ULN or total bilirubin >1 to 1.5 times ULN with any AST).

The effect of severe hepatic impairment (total bilirubin >3 times ULN with any AST) on dordaviprone pharmacokinetics is unknown.

Pediatric Patients

The exposure of dordaviprone in pediatrics weighing 10 kg and higher is predicted to be within the range of exposures predicted in adults at the recommended dosage.

Renal Impairment

Following a single oral dose of 375 mg (0.6 times the maximum approved recommended dose), dordaviprone AUC increased by 1.5-fold and C_max by 1.1-fold in subjects with severe renal impairment (CLcr <30 mL/min, estimated by the Cockcroft-Gault equation).

Hepatic Impairment

Following a single oral dose of 125 mg (0.2 times the maximum approved recommended dose) dordaviprone AUC increased by 1.5-fold and C_max by 1.2-fold in subjects with moderate hepatic impairment (Child Pugh class B).

Drug Interaction Studies

Clinical Studies and Model-Informed Approaches

CYP3A4 Inhibitors:Dordaviprone C_max increased by 2-fold and AUC increased by 4-fold following concomitant administration of itraconazole (strong CYP3A4 inhibitor) 200 mg once daily for 8 days.

Dordaviprone C_max is predicted to increase by ~1.5-fold and AUC by 2.5-fold following concomitant administration of fluconazole or erythromycin (moderate CYP3A4 inhibitor).
