Study AG881-C-004 is a phase 3, multicenter, randomized, double-blind, placebo-controlled study comparing the efficacy of AG-881 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 366 participants are planned to be randomized 1:1 to receive orally administered AG-881 40 mg QD or placebo.
Name: AG-881
Name: Matching Placebo
Description: The FACT-Br is a participant-reported measure designed to assess the quality of life for participants with brain tumors. The FACT-Br is a measure comprising the following subscales: Physical Well-Being, Functional Well-Being, Emotional Well-Being, and Social Well-Being subscales from the FACT-G, with the addition of a brain tumor- specific subscale.
Measure: Health-Related Quality of Life as Measured by Functional Assessment of Cancer Therapy-Brain Questionnaire (FACT-Br) Time: Up to approximately 30 monthsAllocation: Randomized
