Study Endpoints
Primary Endpoints
Part 1 & 2: Incidence of Adverse Events (AEs)
Start of treatment up to 30 days after last dose or start of new anticancer therapy (whichever occurs first)

An adverse event (AE) was any untoward medical occurrence in a participant who received study medication without regard to possibility of causal relationship to it. SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/ incapacity; congenital anomaly. AEs included both serious and all non-serious AEs.

PART 1 & 2: Number of participants with laboratory abnormalities
From start of treatment up to 30 days after last dose or start of new anticancer therapy, whichever occurred first

Number of participants with laboratory test abnormalities. Laboratory test parameters included hematology, coagulation, liver function, renal function, electrolytes, clinical chemistry, and urinalysis (dipstick and microscopy).

Part 1: Number of participants with Dose-limiting toxicities (DLT)
Baseline up to 28 days

Any of the prespecified AEs that are attributable to one, the other, or both study treatments, occurring in the DLT observation period are considered DLTs, excluding toxicities clearly due to underlying disease or extraneous causes

Part 2: Objective Response - Number of Participants With Objective Response (alone or in combination)
Baseline and every 8 to 12 weeks through time of confirmed disease progression, death, unacceptable toxicity, or through study completion, approximately 2 years'

Percentage of participants with objective response-based assessment of complete response (CR) or partial response (PR) according to Response Evaluation Criteria in Solid Tumors (RECIST v1.1) for overall response rate (ORR), progression free survival (PFS), and overall survivor (OS) assessed by the Investigator.

Secondary Endpoints
Part 1 & 2: Maximum Observed Serum Concentration (Cmax)
baseline through end of Cycle 1 (All cycles are 28 days except part 2b Cohort C2 which are 21 days)
Part 1& 2: Time to Reach Maximum Observed Serum Concentration (Tmax)
Baseline through end of Cycle 1 (All cycles are 28 days except part 2b Cohort C2 which are 21 days)
Part 1 & 2: Serum Area Under the Curve From Time Zero to Last Quantifiable Concentration (AUClast)
Baseline through end of Cycle 1 (All cycles are 28 days except part 2b Cohort C2 which are 21 days)
