-Risk management plan information submitted by the sponsor.
The Sponsor demonstrated the efficacy of Voranigo in patients in a pivotal clinical study (Study AG881-C-004), "INDIGO", a phase 3, multi-centre, randomised, double-blind, placebo-controlled study of vorasidenib in subjects with residual or recurrent Grade 2 glioma with an isocitrate dehydrogenase (IDH)1 or IDH2 mutation. Vorasidenib is an inhibitor of the isocitrate dehydrogenase-1 (IDH1) and isocitrate dehydrogenase-2 (IDH2) proteins that carry certain mutations. As a result, a substance called 2-hydroxyglutarate (2-HG) is overproduced which contributes to the formation of cancer cells.
The primary study objective was to demonstrate the efficacy of vorasidenib based on radiographic progression-free survival compared with placebo in subjects with residual or recurrent Grade 2 oligodendroglioma and astrocytoma with an IDH1 or IDH2 mutation who have undergone surgery as their only treatment.
Voranigo was granted priority review determination and orphan designation (for the orphan
indication of “Treatment of IDH-mutant diffuse glioma”) on the 6th of December 2023.

The recommended dose of Voranigo in adults and adolescents 12 years of age and older:
• 40 mg taken orally once daily for patients weighing at least 40 kg
• 20 mg taken orally once daily for patients weighing less than 40 kg
There are no data from the use of vorasidenib in pregnant women.
Pregnancy testing is recommended in women of childbearing potential prior to starting treatment with Voranigo.
Voranigo is not recommended during pregnancy and in women of childbearing potential not using contraception. Pregnant women, women of childbearing potential or male patients with female partners of childbearing potential should be advised on the potential risk to a fetus.
Vorasidenib caused embryofetal toxicity in pregnant rats and rabbits. Higher incidences of resorptions and delayed ossification were observed in rats and rabbits at 10 and 6 mg/kg/day, respectively, resulting in systemic exposures ≥27- and 5-fold higher than the clinical exposure based on AUC. Visceral malformations (malpositioned kidney and testes) were seen in rats at 75 mg/kg/day (100-fold higher than the clinical exposure at the daily recommended dose). It is not known whether vorasidenib could cause fetal harm when administered to a pregnant woman.
Women of childbearing potential and males with female partners of childbearing potential should use effective non-hormonal contraception during treatment with VORANIGO and for at least 3 months after the last dose. Since the effect of vorasidenib on the metabolism and efficacy of systemically acting hormonal contraceptives has not been investigated, barrier methods should be applied as a second form of contraception to avoid pregnancy.
Voranigo was approved to treat Grade 2 astrocytoma or oligodendroglioma with a susceptible isocitrate dehydrogenase-1 (IDH1) mutation or isocitrate dehydrogenase-2 (IDH2) mutation in adults and paediatric patients 12 years and older, who are not in need of immediate chemotherapy or radiotherapy following surgical intervention.
Voranigo (Vorasidenib citrate) is to be included in the Black Triangle Scheme. The PI and CMI for Voranigo must include the black triangle symbol and mandatory accompanying text for five years, which starts from the date of first supply of the product.
The Voranigo EU-Risk Management Plan (RMP) (version 0.1, dated 19 December 2023, data lock point 6 September 2022), with Australian Specific Annex (version 0.2, dated 4 April 2024), included with submission PM-2023-06126-1-4, and any subsequent revisions, as agreed with the TGA will be implemented in Australia. An obligatory component of risk management plans is routine pharmacovigilance. Routine pharmacovigilance includes the submission of periodic safety update reports (PSURs).
Conduct and submit to the TGA for evaluation:
- An in vivo micronucleus assay in rat bone marrow following oral dosing with AGI-69460 to assess genotoxicity.
- A study to assess the carcinogenicity of vorasidenib and AGI-69460 in Wistar rats.
- A study to assess the carcinogenicity of vorasidenib and AGI-69460 in transgenic RasH2 mice.
