Overview
Brief Summary
This study will evaluate the efficacy, safety, and pharmacokinetics of treatment combinations in cancer immunotherapy (CIT)-naive participants with resectable Stage III melanoma (Cohort 1) and in participants with Stage IV melanoma (Cohort 2). The study is designed with the flexibility to open new treatment arms as new treatments become available, close existing treatment arms that demonstrate minimal clinical activity or unacceptable toxicity, and modify the participant population.

Outcomes
Primary Outcomes
Pathologic Response Rate (pRR) for Cohort 1 as Determined by Independent Pathologic Review
Time Frame: Time of surgery (scheduled at Week 7)
pRR was defined as the percentage of participants with pathologic complete response (pCR), pathologic near complete response (pnCR), and pathologic partial response (pPR) as determined by an independent pathologic review. pCR was defined as a complete absence of viable tumor cells, pnCR as \> 0 to ≤ 10% of viable tumor cells, and pPR was defined as \> 10 to ≤ 50% of viable tumor cells in the dissected lymph node. Participants with missing or no pathologic response assessment, including participants who did not proceed to complete lymph node dissection (CLND), were classified as non-responders. pRR was calculated for each arm along with 95% confidence intervals (CIs) using Clopper-Pearson method. The difference in pRR between the experimental arms and the control arm was calculated, along with 95% CIs using the Wald method with continuity correction.
Objective Response Rate (ORR) for Cohort 2 as Determined by the Investigator
Time Frame: From randomization up to approximately 3.6 months
ORR was defined as the percentage of participants with a complete response (CR) or partial response (PR) on two consecutive occasions ≥4 weeks apart, as determined by the investigator according to Response Evaluation Criteria in Solid Tumors, Version 1.1 (RECIST v1.1). CR was defined as the disappearance of all target lesions or any pathological lymph nodes (whether target or non-target) having a reduction in the short axis to \<10 millimeters (mm). PR was defined as at least a 30% decrease in the sum of diameters of all target lesions, taking as reference the baseline sum of diameters, in the absence of CR. Participants with missing or no response assessments were classified as non-responders. ORR was calculated for each arm, along with 95% CIs using Clopper-Pearson method.
