Phase 3 Study of Vorasidenib (S095032/AG-881) in Asian Participants With Residual or Recurrent Grade 2 Glioma With an IDH1 orIDH2 Mutation

The objective of this study is to determine the efficacy, safety, and pharmacokinetics of vorasidenib in Asian participants with residual or recurrent Grade 2 glioma with an IDH1 or IDH2 mutation. The study will begin with a safety lead-in (SLI) phase and then will transition to a randomized double-blind placebo-controlled phase. During the study participants will have study visits on day 1 and 15 of the first two cycles, and then only on day 1 of treatment cycles in the frequency included in the study schedule of assessments. All participants will have an end of treatment visit within 7 days after their last dose of study treatment. Approximately 28 (+5) days after treatment has ended, a safety follow-up visit will occur. Study visits may include questionnaires, blood tests, ECG, vital signs, and a physical examination. Beginning at the end of treatment visit participants will be contacted by phone every 6 months for overall survival up to 5 years after the last participant is randomized or until death, withdrawal of consent from overall study participation, lost to follow-up, or sponsor ending the study, whichever occurs first.
