Study Endpoints

Primary Endpoints

Part A: Number of Participants Who Experienced Dose Limiting Toxicities (DLTs) Assessed Using National Cancer Institute (NCI) Common Toxicity Criteria for Adverse Events (CTCAE) Version 5.0
Day 1 up to Day 21

A DLT was defined as any Grade more than or equal to \>= 3 nonhematologic Adverse Event(AE) or any Grade\>= 4 hematologic,, occurring during the DLT period that is related to any of the study interventions. In addition, a DLT is considered: Grade 3 thrombocytopenia with medically concerning bleeding, Any febrile neutropenia.
