Study Endpoints
Primary Endpoints
Incidence of dose-limiting toxicities (DLTs)
Up to cycle 2 day 21 (1 cycle = 21 days)

Defined as any treatment-related grade \>= 3 non-hematological or hematological adverse events. The incidence of DLT at each dose level will be summarized using the proportion and exact binomial confidence interval. Dose-limiting toxicities will specifically be reported for the DLT evaluation period using the maximum tolerated dose (MTD)-evaluable population. The MTD will be identified using isotonic regression.

Secondary Endpoints
Incidence of treatment-emergent adverse events (AEs) and serious AEs
Up to 30 days after last dose of study intervention
Objective response rate (ORR)
Up to 6 months after initiating study intervention
Disease control rate (DCR)
Up to 6 months after initiating study intervention
