What is Vorasidenib?

Vorasidenib tablets treat brain cancers called astrocytoma or oligodendroglioma with a specific mutation called IDH1 or IDH2. It is a once-daily tablet used to help manage IDH-mutant astrocytoma or oligodendroglioma cancer after surgery. Vorasidenib brand name is Voranigo by Servier Pharmaceuticals.

Astrocytoma and oligodendroglioma are a type of glioma, a tumor that develops from cells within the central nervous system (CNS). Mutations in the IDH1 and IDH2 genes cause abnormal cell growth, potentially leading to tumors. Vorasidenib works by blocking these mutant enzymes, reducing tumor activity.

Vorasidenib drug class is a DH1 and IDH2 inhibitor (isocitrate dehydrogenase-1 (IDH1) and isocitrate dehydrogenase-2 (IDH2) inhibitors). Vorasidenib mechanism of action involves blocking IDH1 and IDH2 enzymes, decreasing 2-hydroxyglutarate (2-HG) production, and partially restoring normal cellular differentiation.
