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. |

Primary Outcome Measures :
- Phase 1: Number of Participants With Treatment-Emergent Adverse Events (TEAEs), Serious Adverse Events (SAEs) and Dose Limiting Toxicities (DLTs) [ Time Frame: Up to 54 months ]This will be evaluated by looking at the number of participants with treatment-related adverse events, serious adverse events (SAEs), and dose-limiting toxicities (DLTs), which are medical problems severe enough to stop study doctors from increasing a treatment dose.

- Phase 2: Progression-Free Survival (PFS) Based on the Lugano Classification Using CT Imaging as the Primary Modality [ Time Frame: Up to 54 months ]
- Phase 2: Disease Control Rate (DCR) Assessed as Percentage of Participants With Disease Control Based on the Lugano Classification Using CT Imaging as the Primary Modality [ Time Frame: Up to 54 months ]
- Phase 2: Overall Survival (OS) Based on the Lugano Classification Using CT Imaging as the Primary Modality [ Time Frame: Up to 54 months ]
- Phase 2: Percentage of Participants With DOR, CR, PR, PFS, DCR,and OS Based on the Lugano Classification Using CT Along With PET Imaging Assessments [ Time Frame: Up to 54 months ]Duration of response (DOR), complete response (CR), partial response (PR), progression-free survival (PFS), disease control rate (DCR)and overall survival (OS)
- Phase 2: Percentage of Participants With Anti-Tumor Activity Based on Assessment Using 2014 Lugano Classification With Lymphoma Response to Immunomodulatory Therapy Criteria (LYRIC) [ Time Frame: Up to 54 months ]Anti-tumor activity in terms of ORR, DOR, CR, PR, and PFS will be evaluated based on assessment using 2014 Lugano Classification with LYRIC.
- Phase 2: Percentage of Participants With Anti-Tumor Activity Based on PTCL Subtypes Anti-tumor activity in terms of ORR, DOR, DCR, CR, and PR will be evaluated based on PTCL subtypes (using both pathology and molecular markers). [ Time Frame: Up to 54 months ]
