Study Arms:
- Phase 1b Dose Escalation (Type: EXPERIMENTAL): Participants will receive intravenous infusions of APR-246 as a lead-in phase on days -14 to -11 starting at Dose Level 1 prior to starting cycle #1 of combination therapy with azacitidine. Combination therapy will consist of APR-246 on days 1-4 and azacitidine on days 4-10 (or days 4-5 and 8-12) of a 28 day cycle.
- Phase 2 Treatment (Type: EXPERIMENTAL): Participants will be treated with APR-246 administered at the maximum tolerated dose (MTD) with azacitidine on a 28 day cycle utilizing the same dosing schedule as in Phase 1b.

Based on this trial design, predict the completion outcome and termination type (if applicable).
