A Phase 2, Multicenter, Clinical Study to Evaluate the Efficacy and Safety of Safusidenib Erbumine in Patients With Isocitrate Dehydrogenase 1 (IDH1) Mutant Glioma

This is a 2-part study. The purpose of Part 1 of the study is to evaluate the efficacy, safety, and pharmacokinetic (PK) characteristics of safusidenib in participants with recurrent/progressive IDH1-mutant World Health Organization (WHO) Grade 2 or Grade 3 glioma.

The purpose of Part 2 will be to evaluate the efficacy of maintenance safusidenib treatment versus placebo in IDH1-mutant Grade 3 astrocytoma with high-risk features or Grade 4 IDH1-mutant astrocytoma, following standard-of-care radiation or chemoradiation and adjuvant temozolomide. Part 2 will be randomized, double blind, and placebo controlled.
