Study of Vorasidenib (AG-881) in Participants With Residual or Recurrent Grade 2 Glioma With an IDH1 or IDH2 Mutation (INDIGO)

Official Title

A Phase 3, Multicentre, Randomized, Double-blind, Placebo-Controlled Study of AG-881 in Subjects With Residual or Recurrent Grade 2 Glioma With an IDH1 or IDH2 Mutation

Summary:

Study AG881-C-004 is a phase 3, multicentre, randomized, double-blind, placebo-controlled study comparing the efficacy of vorasidenib to placebo in participants with residual or recurrent Grade 2 glioma with an IDH1 or IDH2 mutation who have undergone surgery as their only treatment. Participants will be required to have central confirmation of IDH mutation status prior to randomization. Approximately 340 participants are planned to be randomized 1:1 to receive orally administered vorasidenib 40 mg QD or placebo.
