Study Summary

Study AG881-C-004 is a phase 3, multicenter, 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.

Primary Outcome

PFS is defined as the time from date of randomization to date of first documented radiographic PD (as assessed by the blinded independent review committee (BIRC) per modified Response Assessment for Neuro-oncology for Low-Grade Gliomas or date of death due to any cause, whichever occurs earlier.
