Time frame
From first dose of study treatment to the data cut-off date of 01 September 2017; overall median time on follow-up in Phase 1 Dose Expansion was 8.3 months (range 0.5 to 32.8 months).

What was measured

Overall survival is defined as the time from first dose to the date of death due to any cause. Participants still alive were censored at the last date known to be alive or at the data cut-off date, whichever was earlier.

Analysis population: All participants in Phase 1 Dose Expansion who received at least one dose of study treatment.

Groups in this outcome

Phase 1 Dose Expansion Arm 1: Enasidenib 100 mg QD

Participants ≥ 60 years old with relapsed, refractory AML or participants of any age if relapsed post-bone marrow transplant (BMT) received 100 mg enasidenib QD on Day 1 to Day 28 of each 28-day treatment cycle until disease progression or development of unacceptable toxicity.

Phase 1 Dose Expansion Arm 2: Enasidenib 100 mg QD

Participants \< 60 years old with R/R AML, excluding participants who relapsed post-BMT, received 100 mg enasidenib QD on Day 1 to Day 28 of each 28-day treatment cycle until disease progression or development of unacceptable toxicity.

Phase 1 Dose Expansion Arm 3: Enasidenib 100 mg QD

Untreated AML participants ≥ 60 years old who declined standard of care received 100 mg enasidenib QD on Day 1 to Day 28 of each 28-day treatment cycle until disease progression or development of unacceptable toxicity.

Phase 1 Dose Expansion Arm 4: Enasidenib 100 mg QD

Participants with advanced hematologic malignancies not eligible for Arms 1 to 3 received 100 mg enasidenib QD on Day 1 to Day 28 of each 28-day treatment cycle until disease progression or development of unacceptable toxicity.
