Study of AG-120 (Ivosidenib) vs. Placebo in Combination With Azacitidine in Participants With Previously Untreated Acute Myeloid Leukemia With an IDH1 Mutation

Study Summary

Study AG120-C-009 is a global, Phase 3, multicenter, double-blind, randomized, placebo-controlled clinical trial to evaluate the efficacy and safety of AG-120 (ivosidenib) + azacitidine vs placebo + azacitidine in adult participants with previously untreated IDH1m AML who are considered appropriate candidates for non-intensive therapy. The primary endpoint is event-free survival (EFS). The key secondary efficacy endpoints are overall survival (OS), rate of complete remission (CR), rate of CR and complete remission with partial hematologic recovery (CRh), and overall response rate (ORR). Participants eligible for study treatment based on Screening assessments will be randomized 1:1 to receive oral AG-120 or matched placebo, both administered in combination with subcutaneous (SC) or intravenous (IV) azacitidine. An estimated 200 participants will take part in the study.

Primary Outcome

EFS was defined as the time from randomization until treatment failure, relapse from remission, or death from any cause, whichever occurs first. Treatment failure was defined as failure to achieve complete remission (CR) by Week 24. CR: Bone marrow blasts \<5% and no Auer rods; absence of extramedullary disease; Absolute neutrophil count (ANC) ≥1.0 × 10\^9 per litre (10\^9/L) (1000 per microlitre \[1000/μL\]); platelet count ≥100 × 10\^9/L (100,000/μL); independence of red blood cell transfusion
