Detailed Description:

The study was redesigned to expand the number of patients analyzed during the Phase 1b stage of the study to determine a safe and effective dose of AG-120 administered with azacitidine for future studies.

The Phase 1b (AG-120 expansion) stage will evaluate the safety, tolerability, and clinical activity of oral AG-120 when administered with Subcutaneous azacitidine.

The Phase 2 stage of the study will no longer include AG-120 administered with azacitidine (IDH1 subjects) and IDH1 patients will not longer be included in the azacitidine alone arm.
