LuciRevu (Revumenib) FAQs and Common Myths—What Patients Need to Know

Frequently Asked Questions About LuciRevu

Q1. What is LuciRevu?
A: LuciRevu is a first-in-class oral medication known as a menin inhibitor. It comes in tablet form and is typically taken twice daily.

Q2. How does LuciRevu work?
A: LuciRevu blocks the interaction between menin and specific proteins (KMT2A fusion or NPM1 mutation), which are essential for the survival of certain leukemia cells. Blocking this pathway helps stop cancer cell growth and promotes the return of healthy blood cell production.

Q3. What is LuciRevu approved for?
A: It is FDA-approved for adults and children (aged 1 year and older) with relapsed or refractory acute leukemia that involves:

• KMT2A rearrangement (a genetic abnormality in AML or ALL)
• NPM1 mutation (common in AML)
  It’s used when other treatments have failed or are not suitable.

Q4. What are the most common side effects?
A: Common side effects include:

• Nausea, vomiting
• Infections
• Fatigue
• Diarrhea or constipation
• Fever with low white blood cell count
• Bleeding, swelling
• Muscle/joint pain
• Abnormal liver function
• Decreased appetite

Q5. Are there serious side effects to watch for?
A: Yes. Serious risks include:

• Differentiation Syndrome (potentially life-threatening)
• Heart rhythm changes (QTc prolongation)
• Serious infections and bleeding
• Liver function issues
  Report any sudden symptoms (fever, swelling, shortness of breath) to your doctor immediately.

Q6. Can I take LuciRevu with other medications or supplements?
A: LuciRevu can interact with many drugs, including:

• Antibiotics (e.g., clarithromycin)
• Antifungals (e.g., ketoconazole)
• NSAIDs
• Herbal supplements like St. John’s Wort
  Avoid grapefruit or grapefruit juice. Always inform your doctor about all medications and supplements you’re taking.

Q7. What if I’m pregnant, trying to conceive, or breastfeeding?
A:

• Pregnancy: LuciRevu may harm an unborn baby. A pregnancy test is required before starting. Use birth control during treatment and for 4 months after.
• Breastfeeding: Do not breastfeed during treatment and for 1 week after the last dose.
• Fertility: LuciRevu may affect fertility in both men and women.

Q8. What should I do if I vomit after taking a dose?
A: Do not take an extra dose. Wait until your next scheduled dose.

Q9. What if I miss a dose?
A: Take it as soon as you remember, as long as the next dose is more than 12 hours away.
Never take two doses within a 12-hour period.

Q10. How does LuciRevu affect blood counts?
A: LuciRevu can lower white blood cells, increasing your risk of infection. Even with normal WBC counts, your immune system may be weakened. Your care team will monitor your blood counts closely.

Q11. Is LuciRevu a type of chemotherapy?
A: No. LuciRevu is a targeted therapy, not traditional chemotherapy. It is sometimes combined with chemo in clinical trials but works by inhibiting a specific protein (menin), not by broadly killing dividing cells.
