Percentage Change From Baseline in Tumor Size

Tumor size was the sum of the longest diameters (or short axis measurements for lymph nodes) of the target lesions (TLs). Percentage change in tumor size was determined for participants with measurable disease at baseline. Baseline for Response evaluation criteria in solid tumors (RECIST) version 1.1 was defined as the last evaluable assessment prior to first IP dose. This outcome measure was assessed only for substudy 1 Part A.

Time frame: Baseline (pre-treatment) up to Week 6 and Week 15

Population: Response evaluable set included all dosed participants who had measurable disease at baseline. Here, n (number analyzed in each raw) signifies the participants with available data that were analyzed for each timepoint for this outcome measure.

Progression Free Survival (PFS)

The PFS was defined as the time from the start of study intervention until the date of objective disease progression or death (by any cause in the absence of progression), regardless of whether the participant withdraws from study intervention or received another anti-cancer therapy prior to progression. This outcome measure was assessed only for substudy 1 Part A.

Time frame: First dose until documented disease progression or study end (1 Year)

Population: Safety set included all participants who received any amount of IP.
