Voranigo (vorasidenib) is a targeted anticancer medication that inhibits mutant isocitrate dehydrogenase 1 (IDH1) and isocitrate dehydrogenase 2 (IDH2) enzymes. It is used for the treatment of grade 2 astrocytoma and oligodendroglioma in adults and adolescents aged 12 years and older (weighing at least 40 kg) who have undergone surgery alone and are not in immediate need of radiation therapy or chemotherapy. Voranigo is specifically designed to cross the blood-brain barrier and reduce the production of the oncometabolite 2-hydroxyglutarate (2-HG), thereby slowing or stopping the growth of IDH-mutant brain tumors. It is taken as a once-daily oral tablet and requires a prescription.

Key Takeaways

  • Voranigo (vorasidenib) is the first oral, brain-penetrant dual IDH1/IDH2 inhibitor approved for grade 2 IDH-mutant astrocytoma and oligodendroglioma, offering patients a targeted treatment option after surgery without the need for immediate radiation or chemotherapy.
  • The drug works by blocking mutant IDH enzymes that overproduce the oncometabolite 2-hydroxyglutarate (2-HG), thereby slowing or halting the growth of brain tumors driven by IDH1 or IDH2 mutations.
  • Liver function must be monitored before and during treatment, as elevated liver enzymes are the most common serious side effect; dose adjustments or treatment interruption may be necessary if hepatotoxicity occurs.
  • Voranigo can reduce the effectiveness of hormonal contraceptives; women and men of reproductive potential must use effective contraception (including a barrier method if using hormonal contraceptives) during treatment and for at least 2 months after the last dose.
  • The tablet must be taken on an empty stomach (no food for 2 hours before and 1 hour after) and swallowed whole; the recommended dose is 40 mg once daily for patients weighing 40 kg or more.

What Is Voranigo and What Is It Used For?

Quick Answer: Voranigo (vorasidenib) is an oral cancer medication that targets mutant IDH1 and IDH2 enzymes in the brain. It is used to treat grade 2 astrocytoma and oligodendroglioma in patients who have had surgery and do not yet need radiation therapy or chemotherapy. It works by reducing the production of an abnormal substance (2-HG) that drives tumor growth.

Voranigo is a targeted anticancer medication containing the active substance vorasidenib. It belongs to a new class of drugs known as isocitrate dehydrogenase (IDH) inhibitors, which represent a breakthrough in the treatment of certain types of brain tumors. Unlike traditional chemotherapy, which broadly attacks fast-dividing cells throughout the body, vorasidenib specifically targets the molecular abnormality that drives tumor growth in IDH-mutant gliomas.

The medication is approved for the treatment of grade 2 astrocytoma and oligodendroglioma in adults and adolescents aged 12 years and older, with a body weight of at least 40 kg, who have undergone surgical resection only and are not in immediate need of radiation therapy or chemotherapy. These are types of diffuse low-grade gliomas — slow-growing brain tumors that arise from the supportive glial cells of the central nervous system. While classified as low-grade, these tumors invariably progress over time and can transform into higher-grade malignancies, making effective early treatment critically important.

Voranigo is used only when the tumor cells harbor mutations in the genes encoding isocitrate dehydrogenase 1 (IDH1) or isocitrate dehydrogenase 2 (IDH2). Before treatment begins, a laboratory test is performed on a sample of the tumor tissue (obtained during surgery) to confirm the presence of an IDH1 or IDH2 mutation. Approximately 70–80% of grade 2 and grade 3 gliomas carry IDH mutations, making this a common molecular feature in lower-grade brain tumors.

How Does Voranigo Work?

The IDH1 and IDH2 proteins play a vital role in cellular energy metabolism. Under normal conditions, these enzymes catalyze the conversion of isocitrate to alpha-ketoglutarate (α-KG) as part of the citric acid cycle (Krebs cycle). When the IDH1 or IDH2 gene is mutated, the resulting abnormal enzyme gains a new, harmful function: instead of producing α-KG, it converts α-KG into the oncometabolite 2-hydroxyglutarate (2-HG).

Elevated levels of 2-HG cause profound epigenetic changes within the cell. Specifically, 2-HG inhibits a family of enzymes called α-KG-dependent dioxygenases, which include histone demethylases and TET (ten-eleven translocation) enzymes involved in DNA demethylation. The resulting hypermethylation of DNA and histones leads to widespread alterations in gene expression, impaired cellular differentiation, and ultimately contributes to the development and progression of cancer. This epigenetic dysregulation is a hallmark of IDH-mutant gliomas.

Vorasidenib is specifically designed to cross the blood-brain barrier — a selective membrane that protects the brain from many substances circulating in the bloodstream. This is a critical advantage, as many drugs cannot reach effective concentrations within the brain. Once inside the brain, vorasidenib binds to and inhibits the mutant IDH1 and IDH2 enzymes, blocking the abnormal production of 2-HG. By reducing 2-HG levels, vorasidenib helps to reverse the epigenetic dysregulation driving tumor growth, thereby slowing or halting the progression of IDH-mutant gliomas.

The clinical efficacy of vorasidenib was demonstrated in the landmark INDIGO phase 3 randomized clinical trial, which showed a statistically significant and clinically meaningful improvement in progression-free survival compared with placebo in patients with residual or recurrent grade 2 IDH-mutant glioma following surgery alone. The trial also showed a significant delay in the time to next intervention (such as radiation or chemotherapy), providing patients with a longer period of preserved quality of life.

First-in-Class Brain-Penetrant IDH Inhibitor

Voranigo is the first oral medication specifically designed to cross the blood-brain barrier and inhibit both mutant IDH1 and mutant IDH2 enzymes simultaneously. This dual inhibition is important because gliomas may harbor mutations in either IDH1 or IDH2, and vorasidenib provides coverage against both variants. The blood-brain barrier penetration sets vorasidenib apart from earlier IDH inhibitors that were primarily developed for blood cancers.

What Should You Know Before Taking Voranigo?

Quick Answer: Do not take Voranigo if you are allergic to vorasidenib or any of its ingredients. Tell your doctor about any liver or kidney problems. Voranigo can harm an unborn child, so effective contraception is required for both men and women during treatment. The drug can also reduce the effectiveness of hormonal contraceptives.

Contraindications

Before starting Voranigo, your healthcare provider needs to determine whether the medication is safe for you. There are specific situations in which Voranigo must not be used.

  • Hypersensitivity: Do not take Voranigo if you are allergic to vorasidenib or any other ingredient in the formulation (including microcrystalline cellulose, croscarmellose sodium, silicified microcrystalline cellulose, magnesium stearate, sodium lauryl sulfate, hypromellose, titanium dioxide, lactose monohydrate, or macrogol).

Warnings and Precautions

Talk to your doctor, pharmacist, or nurse before taking Voranigo if you have problems with your kidneys or if you have problems with your liver. Your healthcare team will assess whether the benefits of treatment outweigh the risks in your particular situation.

Elevated liver enzymes are the most common serious side effect associated with Voranigo. In clinical trials, increases in alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were reported in a significant proportion of patients. Most elevations were grade 1 or 2 (mild to moderate) and were manageable with dose modifications or temporary interruption of therapy. However, more severe hepatotoxicity can occur, making regular monitoring essential throughout the course of treatment.

Pregnancy and Breastfeeding

Voranigo should not be used during pregnancy because it may harm the unborn child. If you are a woman who could become pregnant, your doctor will perform a pregnancy test before starting treatment. If you become pregnant while taking Voranigo, contact your doctor immediately.

Contraception Requirements

Women who could become pregnant must use effective contraception during treatment and for at least 2 months after the last dose. Men whose partners could become pregnant must also use effective contraception during treatment and for at least 2 months after the last dose. Importantly, Voranigo can reduce the effectiveness of hormonal contraceptives (such as birth control pills, patches, or implants). If you or your partner uses a hormonal contraceptive, you must also use a barrier method (such as a condom or diaphragm) to prevent pregnancy.

It is unknown whether vorasidenib passes into breast milk. You should not breastfeed while taking Voranigo and for at least 2 months after the last dose. If you are breastfeeding, discuss alternative feeding options with your healthcare provider before starting treatment.

Voranigo may affect your ability to have children (fertility). If you are concerned about your fertility, speak with your doctor before starting treatment to discuss your options, which may include fertility preservation measures.

Children and Adolescents

Voranigo is approved for use in adolescents aged 12 years and older who weigh at least 40 kg. The safety and efficacy of Voranigo have not been established in children under 12 years of age, and it should not be given to this age group.

Special Populations

Voranigo is not expected to affect the ability to drive or use machines. However, some patients may experience dizziness or fatigue during treatment. If you experience these symptoms, use caution when driving or operating machinery until you know how the medication affects you.

The tablets contain lactose (a sugar found in milk and dairy products). If you have been told by your doctor that you have an intolerance to certain sugars, contact your doctor before taking this medicine. The tablets also contain less than 1 mmol (23 mg) sodium per tablet, meaning they are essentially sodium-free.

How Does Voranigo Interact with Other Drugs?

Quick Answer: Voranigo has significant interactions with many medications. Some drugs can increase Voranigo levels (raising the risk of side effects), others can decrease its effectiveness, and Voranigo itself can reduce the effectiveness of numerous other medications including hormonal contraceptives, blood thinners, immunosuppressants, and many more.

Voranigo can interact with many other medications because it affects the body's drug-metabolizing enzyme systems, particularly the cytochrome P450 (CYP) pathway. It is essential to tell your doctor or pharmacist about all medications you are taking, have recently taken, or plan to take, including prescription drugs, over-the-counter medicines, vitamins, and herbal supplements.

Drugs That Increase Voranigo Levels

Certain medications can increase the concentration of vorasidenib in your blood, which may raise the risk of side effects. These drugs inhibit the enzymes that metabolize vorasidenib and include:

  • Ciprofloxacin — an antibiotic used to treat bacterial infections
  • Fluvoxamine — an antidepressant used to treat depression and obsessive-compulsive disorder

If you are taking either of these medications, your doctor may need to adjust your Voranigo dose or consider alternative treatments.

Drugs That Decrease Voranigo Effectiveness

Some medications can reduce the concentration of vorasidenib in your blood, potentially making it less effective at controlling your brain tumor. These drugs induce the enzymes that break down vorasidenib and include:

  • Rifampicin — used to treat tuberculosis and certain other infections
  • Phenytoin — used to treat epilepsy and seizures

Drugs Whose Effectiveness May Be Reduced by Voranigo

Voranigo is a CYP enzyme inducer, meaning it can accelerate the metabolism of many other drugs, reducing their blood levels and potentially making them less effective. The following table lists key medications affected by Voranigo:

Medications Whose Effectiveness May Be Reduced by Voranigo
Medication Category Used For
Alfentanil Anesthetic Pain management during surgery
Carbamazepine, Fosphenytoin, Phenobarbital, Phenytoin Antiepileptics Seizures and epilepsy

This is not a complete list of all possible drug interactions. There may be additional medications that can interact with Voranigo beyond those listed here. Always consult your doctor or pharmacist before starting, stopping, or changing any medication while on Voranigo therapy.

Important Note for Glioma Patients Taking Antiepileptic Drugs

Many patients with brain tumors take antiepileptic medications to control or prevent seizures. Several of these medications (including phenytoin, carbamazepine, phenobarbital, and valproic acid) interact with Voranigo. Your doctor may need to adjust the doses of your antiepileptic medications or switch to alternatives that do not interact with Voranigo. Never change or stop your antiepileptic medication without consulting your doctor.

What Is the Correct Dosage of Voranigo?

Quick Answer: The recommended dose is 40 mg (one 40 mg tablet) taken once daily by mouth, on an empty stomach. The tablet must be swallowed whole. Treatment continues for as long as your doctor determines it is beneficial.

Always take Voranigo exactly as your doctor or pharmacist has told you. Do not change the dose or stop taking Voranigo without first talking to your doctor. The medication is taken by mouth (orally) once daily, and you should try to take it at the same time each day to maintain consistent drug levels in your body.

Dose reduction (if needed) 10 mg once daily For management of side effects (e.g., liver enzyme elevations)
Patients <40 kg Not recommended Safety and dosing not established
Children under 12 years Not recommended Not studied in this age group

Missed Dose

If you miss a dose of Voranigo, the action you should take depends on how much time has passed:

  • Less than 6 hours late: Take the missed dose as soon as you remember, then take your next dose at the regular scheduled time.
  • More than 6 hours late: Skip the missed dose entirely and take your next dose at the regular scheduled time.

Do not take a double dose to make up for a missed one. Try to set a daily reminder or alarm to help you remember to take your medication at the same time each day.

Overdose

If you accidentally take more tablets than prescribed, contact your doctor, pharmacist, or nurse immediately. You may need urgent medical attention. Keep the medication container with you so that healthcare professionals can identify what you have taken and how much.

Do Not Stop Treatment Without Medical Advice

Do not stop taking Voranigo unless your doctor tells you to. It is important to take Voranigo every day for as long as your doctor has prescribed it. Stopping treatment prematurely may allow the tumor to progress. If you have concerns about side effects or your treatment, discuss them with your healthcare team before making any changes.

What Are the Side Effects of Voranigo?

Quick Answer: The most common side effects of Voranigo include elevated liver enzymes (detected through blood tests), abdominal pain, diarrhea, decreased platelet count, fatigue, and dizziness. Less common side effects include high blood sugar, decreased appetite, low phosphate levels, shortness of breath, and acid reflux. Report any signs of liver problems immediately.

Like all medicines, Voranigo can cause side effects, although not everyone experiences them. The side effects listed below are based on clinical trial data and post-marketing surveillance. Your healthcare team will monitor you for these effects through regular clinical assessments and blood tests throughout your treatment.

Serious Side Effects

If you experience serious side effects, stop taking Voranigo and contact your doctor immediately. Your doctor may need to reduce the dose, pause treatment, or discontinue it entirely depending on the severity.

Side Effects by Frequency

Very Common

May affect more than 1 in 10 people

  • Elevated liver enzymes in the blood (ALT, AST) — detected through routine blood tests
  • Abdominal pain (stomach pain)
  • Diarrhea
  • Decreased platelet count (thrombocytopenia) — platelets help blood to clot; detected through blood tests; may lead to easy bleeding or bruising
  • Fatigue (tiredness)
  • Dizziness

Common

May affect up to 1 in 10 people

  • Elevated blood sugar levels (hyperglycemia)
  • Decreased appetite
  • Low phosphate levels in the blood (hypophosphatemia) — detected through blood tests; may cause confusion or muscle weakness
  • Shortness of breath (dyspnea)
  • Gastroesophageal reflux disease (acid reflux) — a condition where stomach acid flows back into the esophagus

Managing Side Effects

Many of the side effects associated with Voranigo are manageable with appropriate medical care and monitoring. Your doctor will schedule regular blood tests to check your liver function, platelet count, blood sugar levels, and phosphate levels. Based on these results, adjustments to your treatment may be made.

Elevated liver enzymes are the most common laboratory abnormality. In most cases, these elevations are mild to moderate and resolve with dose reduction or temporary treatment interruption. Severe hepatotoxicity is less common but requires immediate medical attention. It is important to attend all scheduled blood test appointments so that any changes can be detected early.

For gastrointestinal side effects such as diarrhea and abdominal pain, your doctor may recommend dietary modifications or prescribe supportive medications. Fatigue is a common side effect that may be managed through appropriate rest, light physical activity, and energy conservation strategies. Dizziness should be reported to your doctor, especially if it affects your ability to drive or perform daily activities safely.

If you experience any side effects that concern you, or if a side effect becomes severe, contact your healthcare team. Even side effects not listed here should be reported, as they contribute to the ongoing monitoring of the medication's safety profile.

Reporting Side Effects

Reporting suspected side effects after a medicine has been authorized is important. It allows continued monitoring of the benefit-risk balance of the medicine. Healthcare professionals and patients are encouraged to report any suspected adverse reactions to their national pharmacovigilance authority (e.g., the FDA MedWatch program in the United States, the Yellow Card Scheme in the United Kingdom, or the EMA's EudraVigilance system in the European Union).

Frequently Asked Questions About Voranigo

Voranigo (vorasidenib) is used to treat IDH-mutant grade 2 astrocytoma and oligodendroglioma in adults and adolescents aged 12 years and older (weighing at least 40 kg) who have undergone surgery only and do not immediately require radiation therapy or chemotherapy. It specifically targets tumors with IDH1 or IDH2 mutations and works by blocking the abnormal IDH enzymes to slow or stop tumor growth.

Voranigo contains vorasidenib, a dual inhibitor of mutant IDH1 and IDH2 enzymes. When these genes are mutated, the IDH enzymes produce excessive amounts of 2-hydroxyglutarate (2-HG), an oncometabolite that drives tumor development. Vorasidenib crosses the blood-brain barrier and blocks these abnormal enzymes, reducing 2-HG levels and thereby slowing or halting glioma growth.

No, Voranigo should not be used during pregnancy as it may harm the unborn child. Women who could become pregnant must use effective non-hormonal contraception (or hormonal contraception plus a barrier method) during treatment and for at least 2 months after the last dose. Men with partners who could become pregnant must also use effective contraception during the same period. Importantly, Voranigo can reduce the effectiveness of hormonal contraceptives, so a barrier method must always be used in addition.

Yes, Voranigo can reduce the effectiveness of hormonal contraceptives such as birth control pills, patches, and implants. This is because vorasidenib induces certain liver enzymes (CYP enzymes) that accelerate the breakdown of hormonal contraceptives. If you or your partner uses a hormonal contraceptive, you must also use a barrier method (such as condoms or a diaphragm) to prevent pregnancy during treatment and for at least 2 months after the last dose.

If you miss a dose by less than 6 hours, take it as soon as you remember and then continue with your regular schedule. If more than 6 hours have passed since your scheduled dose, skip the missed dose and take your next dose at the regular time. Do not take a double dose to make up for a missed one.

Voranigo must be taken on an empty stomach (no food for at least 2 hours before and 1 hour after) because food can affect how the drug is absorbed into your body. Eating around the time of dosing may alter the amount of vorasidenib that reaches your bloodstream, potentially reducing its effectiveness or changing its safety profile. Following the fasting instructions ensures consistent and optimal drug absorption.
