VORANIGO® dosing and management

VORANIGO is taken orally at the same time each day with or without food at home, at work, or wherever is best for your patients1

VORANIGO tablets are supplied in two strengths: 40 mg or 10 mg tablets in 30-count bottles

Instruct your patients on how to take VORANIGO

Swallow tablets whole with water with or without food.
Do not split, crush, or chew tablets.

Treatment considerations for VORANIGO and recommended dosage reductions for adverse reactions (ARs)1

Initial assessment and monitoring liver laboratory tests

Before initiating VORANIGO:

  • Evaluate blood chemistry and liver laboratory tests
  • Verify pregnancy status in females of reproductive potential

During treatment with VORANIGO:

  • The VORANIGO USPI does not include recommendations for electrocardiogram monitoring before or during treatment

Monitor liver laboratory tests (AST, ALT, GGT, total bilirubin, alkaline phosphatase) at the following intervals

Recommended monitoring intervals for liver laboratory tests. Recommended monitoring intervals for liver laboratory tests.

Reduce the dose, withhold, or permanently discontinue VORANIGO based on severity

Pregnancy, fertility, family planning, and breast-feeding considerations1

  • Based on animal embryo-fetal toxicity studies, VORANIGO can cause fetal harm when administered to pregnant women
  • Based on findings in animals, VORANIGO may impair fertility in females and males of reproductive potential. The effects on female and male fertility were reversible in monkeys and were not reversible in rats. No fertility information is currently available for the use of VORANIGO in humans
  • Advise females of reproductive potential to use effective nonhormonal contraception during treatment with VORANIGO and for 3 months after the last dose. VORANIGO can render some hormonal contraceptives ineffective
  • Advise male patients with female partners of reproductive potential to use effective contraception during treatment with VORANIGO and for 3 months after the last dose
  • Because of the potential for adverse reactions in breastfed children from VORANIGO, advise women not to breastfeed during treatment with VORANIGO and for 2 months after the last dose
The VORANIGO Patient Brochure can provide your patients with more information about dosing and treatment considerations

Recommended VORANIGO dosage reductions for ARs1

Adjustments to treatment for ARs

Additional blood counts, including liver laboratory tests, and dose modifications may be recommended for increases in ALT, AST, and total bilirubin based on severity1

Dosage interruptions, reductions, and discontinuations in patients treated with VORANIGO in the INDIGO trial1

Dosage interruptions:

  • Dosage interruptions of VORANIGO due to an AR occurred in 30% of patients
  • ARs which required dose interruption in ≥5% of patients included ALT increased (14%), COVID-19 (9%), and AST increased (6%)

Discontinuations:

  • ARs which resulted in permanent discontinuation of VORANIGO in ≥2% of patients included ALT increased (3%)

Dose reductions:

  • Dose reductions of VORANIGO due to an AR occurred in 11% of patients
  • ARs which required dose reduction in ≥5% of patients included ALT increased (8%)

Discontinuations:

  • ARs which resulted in permanent discontinuation of VORANIGO in ≥2% of patients included ALT increased (3%)

IMPORTANT SAFETY INFORMATION

INDICATION

VORANIGO (40 mg tablets) is indicated for the treatment of adult and pediatric patients 12 years and older with Grade 2 astrocytoma or oligodendroglioma with a susceptible isocitrate dehydrogenase-1 (IDH1) or isocitrate dehydrogenase-2 (IDH2) mutation, as detected by an FDA-approved test, following surgery including biopsy, sub-total resection, or gross total resection.

IMPORTANT SAFETY INFORMATION

WARNINGS AND PRECAUTIONS

Hepatotoxicity: VORANIGO can cause hepatic transaminase elevations, which can lead to hepatic failure, hepatic necrosis, and autoimmune hepatitis. Monitor liver laboratory tests (AST, ALT, GGT, total bilirubin, and alkaline phosphatase) prior to the start of VORANIGO, every 2 weeks during the first 2 months of treatment, then monthly for the first 2 years of treatment, and as clinically indicated, with more frequent testing in patients who develop transaminase elevations. Reduce the dose, withhold, or permanently discontinue VORANIGO based on severity.

Embryo-Fetal Toxicity: Based on findings from animal studies, VORANIGO can cause fetal harm when administered to a pregnant woman. Advise pregnant women and females of reproductive potential of the potential risk to a fetus. Advise females of reproductive potential to use effective nonhormonal contraception during treatment with VORANIGO and for 3 months after the last dose, since VORANIGO can render some hormonal contraceptives ineffective. Advise male patients with female partners of reproductive potential to use effective contraception during treatment with VORANIGO and for 3 months after the last dose.

ADVERSE REACTIONS

The most common (≥15%) adverse reactions included fatigue, headache, COVID-19, musculoskeletal pain, diarrhea, nausea, and seizure. Grade 3 or 4 (≥2%) laboratory abnormalities were ALT increased, AST increased, GGT increased, and neutrophils decreased.

DRUG INTERACTIONS

Avoid concomitant use of VORANIGO with strong and moderate CYP1A2 inhibitors. Avoid concomitant use with moderate CYP1A2 inducers and smoking tobacco. Avoid concomitant use with CYP3A substrates, where a minimal concentration change can reduce efficacy. If concomitant use of hormonal contraception cannot be avoided, use nonhormonal contraception methods.

LACTATION

Advise women not to breastfeed during VORANIGO treatment and for 2 months after the last dose.

IMPAIRED FERTILITY

VORANIGO may impair fertility of females and males of reproductive potential.
