Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - Tolinapant
Treatment: Drugs - Decitabine + Cedazuridine

Experimental: Phases 1 and 2: Tolinapant + Oral Decitabine/Cedazuridine - Tolinapant, orally, once daily (QD) on Days 1 to 7 and 15 to 21 of each 28-day cycle in combination with oral decitabine/cedazuridine fixed-dose combination (FDC) tablet, QD on days determined by the Lead-in Phase during each 28-day cycle. The starting dose of tolinapant will be escalated stepwise in successive cohorts until the RP2D is determined.

Based on RP2D and results determined from Phase 1 participants would receive tolinapant at the identified RP2D in combination with decitabine/cedazuridine, FDC tablet, orally, QD on days determined by the Lead-in Phase during each 28-day cycle in Phase 2.

Experimental: Phase 1: Oral Decitabine/Cedazuridine - Decitabine/cedazuridine FDC tablet, orally, QD on days determined by the Lead-in Phase during each 28-day cycle.
