On September 22, 2025 Servier, an independent international pharmaceutical group governed by a foundation, reported that the European Commission (EC) has approved VORANIGO (vorasidenib) for the treatment of predominantly non-enhancing Grade 2 astrocytoma or oligodendroglioma with an isocitrate dehydrogenase-1 (IDH1) R132 or isocitrate dehydrogenase-2 (IDH2) R172 mutation in adult and adolescent patients aged 12 years and older and weighing at least 40 kg who only had surgical intervention and who are not in immediate need of radiotherapy or chemotherapy (Press release, Servier, SEP 22, 2025, View Source [SID1234656157]). The decision to approve VORANIGO as the first targeted therapy to treat Grade 2 IDH-mutant glioma follows a positive opinion from the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) in July 2025.

Gliomas are types of brain cancer that can hinder normal brain function and cause a variety of symptoms. Diffuse gliomas with IDH mutations represent the most common malignant primary brain tumors diagnosed in adults younger than 50 years of age. Historically, treatment options have been limited, and tumors continue to grow and infiltrate normal brain tissue without treatment.1,2,3
"Today’s EU approval of VORANIGO is a landmark moment for people in the EU living with IDH-mutated glioma who have been waiting more than two decades for new treatment options. VORANIGO is the first EMA-approved therapy specifically designed to target mutant IDH enzymes in Grade 2 glioma and represents a long-awaited shift in the treatment paradigm. As a leader in precision medicine, we’re grateful to the researchers, patients and advocates who have helped expand our understanding of IDH inhibition and bring this breakthrough to the EU," said Islam Hassan, Global Head of Development-Neuro-Oncology & Senior Director, LS/LCM at Servier.
Decisions by the EC are applicable in the 27 member states of the EU, as well as Norway, Liechtenstein, and Iceland.
The approval of VORANIGO is supported by results from the pivotal Phase 3 INDIGO clinical trial published in The New England Journal of Medicine and presented during the Plenary Session at the 2023 Annual Meeting of the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper), which showed that VORANIGO significantly extended progression-free survival (PFS) and time to next intervention (TTNI) when compared to placebo. The INDIGO study showed that VORANIGO was well tolerated, and its safety profile was consistent with results from the Phase 1 studies. The most common (≥15%) adverse reactions were fatigue, COVID-19, musculoskeletal pain, diarrhea and seizure.4
VORANIGO has also been granted marketing authorization in the United States, Canada, Australia, Israel, the United Arab Emirates, Saudi Arabia, Switzerland, Brazil, the United Kingdom, and Japan. Servier has submitted marketing authorization applications in several other regions as well and reviews by the respective health authorities are ongoing.
