The primary objectives of Phase 1 Dose Escalation/Part 1 Expansion are: * To assess the safety and tolerability of treatment with enasidenib administered continuously as a single agent dosed orally on Days 1 to 28 of a 28-day cycle in participants with advanced hematologic malignancies. * To determine the maximum tolerated dose (MTD) or maximum administered dose (MAD) and/or the recommended Phase 2 dose (RP2D) of enasidenib in participants with advanced hematologic malignancies. The primary objective of Phase 2 is: • To assess the efficacy of enasidenib as treatment for participants with relapsed or refractory (R/R) acute myelogenous leukemia (AML) with an IDH2 mutation.

- Toxicity severity was graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) Version 4.03. A DLT was defined as: • Non-hematologic toxicities: CTCAE ≥ Grade 3 with the exception of ≥ Grade 3 blood bilirubin increases in participants with a uridine diphosphate- glucuronosyltransferase 1 family, polypeptide A1 (UGT1A1) mutation. In participants with a UGT1A1 mutation, blood bilirubin increases of \> 5× upper limit of normal (ULN) were considered a DLT. • Hematologic toxicities: Prolonged myelosuppression, defined as persistence of ≥ Grade 3 neutropenia or thrombocytopenia (by NCI CTCAE v4.03), leukemia-specific criteria, i.e., marrow cellularity \<5% on Day 28 or later from the start of study drug without evidence of leukemia) at least 42 days after the initiation of Cycle 1 therapy. Leukemia-specific grading was used for cytopenias (based on percentage decrease from Baseline: 50 to 75% = Grade 3, \>75% = Grade 4)

Full study description
- brief Summary
- The primary objectives of Phase 1 Dose Escalation/Part 1 Expansion are: * To assess the safety and tolerability of treatment with enasidenib administered continuously as a single agent dosed orally on Days 1 to 28 of a 28-day cycle in participants with advanced hematologic malignancies. * To determine the maximum tolerated dose (MTD) or maximum administered dose (MAD) and/or the recommended Phase 2 dose (RP2D) of enasidenib in participants with advanced hematologic malignancies. The primary objective of Phase 2 is: • To assess the efficacy of enasidenib as treatment for participants with relapsed or refractory (R/R) acute myelogenous leukemia (AML) with an IDH2 mutation.
