Time frame
Response assessments were performed every 28 days through Month 12 and every 56 days thereafter until the end of treatment; median duration of treatment exposure in Phase 2 was 5.3 months (range 0.4 to 22.5 months).

What was measured

The percentage of participants achieving a complete response (CR), CR with incomplete neutrophil recovery (CRi), or a CR with incomplete platelet recovery (CRp) based on the 2003 revised IWG criteria for AML, assessed by the Investigator. CR: - ANC \> 1.0 x10⁹/L - Platelet count \> 100 x10⁹/L - Bone marrow (BM) blasts \< 5% - Absence of blasts with Auer rods - Independence of red cell transfusions CRi: - All CR criteria except for residual neutropenia (ANC \< 1.0 x 10⁹/L CRp: - All CR criteria except for residual thrombocytopenia (platelet counts \< 100 x 10⁹/L)

Analysis population: All participants In Phase 2 with R/R AML who received at least 1 dose of study treatment.

Groups in this outcome

Phase 2: Enasidenib 100 mg QD

Participants received enasidenib 100 mg QD on Day 1 to Day 28 of each 28-day treatment cycle until disease progression or development of unacceptable toxicity.
