Modeyso is the brand name for dordaviprone, a targeted anti-cancer medication used to treat diffuse midline glioma with an H3 K27M mutation,an aggressive brain tumour affecting both adults and children aged 1 year and older.

Modeyso (dordaviprone) is available as oral capsules in the following strengths:

• 125 mg

Modeyso is indicated for use in adult and pediatric patients aged 1 year and older with diffuse midline glioma that harbors an H3 K27M mutation and has progressed following prior therapy. This approval was granted under the FDA’s accelerated approval pathway, making Modeyso the first, and currently only, systemic treatment option for this rare and aggressive form of brain tumor.

Modeyso works by inhibiting specific pathways that drive tumor growth in diffuse midline glioma with the H3 K27M mutation. It targets cancer cells to slow or stop their proliferation, helping manage disease progression in patients whose tumors have continued to grow following prior therapy. Modeyso works by activating the mitochondrial protease ClpP and inhibiting the dopamine D2 receptor, helping to slow tumour growth and induce cancer cell death.

Modeyso (dordaviprone) is administered as an oral capsule once weekly. The recommended dosage is:

• Adults and pediatric patients weighing ≥52.5 kg: 625 mg orally once weekly.
• Pediatric patients aged 1 year and older weighing between 10 kg and <52.5 kg: The dosage varies based on body weight, ranging from 125 mg to 500 mg once weekly.

Modeyso should be taken on an empty stomach, at least 1 hour before or 3 hours after eating. If swallowing capsules is not possible, the contents can be mixed with approximately 15 to 30 mL of liquid (such as water, apple juice, lemonade, or a sports drink) before ingestion.
Always follow your healthcare provider’s instructions regarding how and when to take Modeyso.

Modeyso is generally safe and effective for most patients when used as directed. However, it may not be suitable if you have certain health conditions or are taking specific medications.

Do not take Modeyso if you have:

• Severe hypersensitivity to dordaviprone or any of its ingredients.
• QTc interval prolongation or a history of arrhythmias.
• Severe liver impairment.
• Known hypersensitivity to dordaviprone or any of its ingredients.
• Used another protease activator or similar medication within the last 24 hours.

Common side effects of Modeyso include:

• Fatigue
• Headache
• Nausea
• Vomiting
• Musculoskeletal pain

These side effects occurred in more than 20% of patients during clinical trials.

Serious side effects of Modeyso are not common. However, you should seek immediate medical attention if you experience:

• Allergic reactions: Rash, itching, swelling, difficulty breathing
• Heart rhythm problems: Palpitations, dizziness, or fainting
• Neurological symptoms: Seizures, confusion, sudden numbness or weakness

Modeyso may be affected by certain drug classes. You should inform your doctor if you are taking:

• Strong or moderate CYP3A4 inhibitors (e.g., ketoconazole, clarithromycin): These can increase dordaviprone exposure, potentially increasing the risk of Modeyso-related adverse reactions.
• Strong or moderate CYP3A4 inducers (e.g., rifampin, carbamazepine): These can decrease dordaviprone exposure, potentially reducing its anti-tumor activity.
• Medications that prolong the QTc interval (e.g., certain antiarrhythmics, antipsychotics): Concomitant use with Modeyso may increase the risk of QTc-associated arrhythmias.

Always discuss all medications, including over-the-counter products, with your healthcare provider before starting Modeyso.
