Brief summary
Substudy 02C is part of a larger research study that is testing experimental treatments for melanoma, a type of skin cancer. The larger study is the umbrella study. The goal of substudy 02C is to evaluate the safety and efficacy of investigational treatment arms in participants with Stage III melanoma who are candidates for neoadjuvant therapy to identify the investigational agent(s) that, when used in combination, are superior to the current treatment options/historical control available. Arm 1: Pembrolizumab + Vibostolimab, Arm 2: Pembrolizumab + Gebasaxturev, and Arm 3: Pembrolizumab were added in the base protocol on 13-Nov-2019, and enrollment into those arms has been completed. Arm 4: Pembrolizumab + MK-4830 was added in Amendment 04 on 20-Dec-2021, and enrollment into that arm has been completed. Arm 5: Favezelimab + Pembrolizumab and Arm 6: Pembrolizumab + all-trans retinoic acid (ATRA) were added in Amendment 06 on 25-Jun-2022, and enrollment is ongoing.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Percentage of participants who experience an adverse event (AE) | Up to ~16 months | An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. The percentage of participants who experience an AE will be reported. |
| Percentage of participants who discontinue study treatment due to an AE | Up to ~12 months | An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. The percentage of participants who discontinue study treatment due to an AE will be reported. |
| Pathological complete response (pCR) rate | Up to ~1.5 months | pCR rate is defined as the proportion of participants with complete absence of viable tumor in the treated tumor bed. Assessments are according to Response Evaluation Criteria in Solid Tumors 1.1 (RECIST 1.1) by central review of the pathology results. RECIST 1.1 has been modified for this study to include a maximum of 10 target lesions and a maximum of 5 target lesions per organ. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Near pathological complete response (near pCR) rate | Up to ~1.5 months | Near pCR is defined as the proportion of participants with \>0% but ≤10% of viable tumor cells in the treated tumor bed. Assessments are according to RECIST 1.1 by central review of the pathology results. RECIST 1.1 has been modified for this study to include a maximum of 10 target lesions and a maximum of 5 target lesions per organ. |
| Pathological partial response (pPR) rate | Up to ~1.5 months | pPR rate is defined as the proportion of participants with \>10% but ≤50% of the treated tumor bed occupied by viable tumor cells. Assessments are according to RECIST 1.1 by central review of the pathology results. RECIST 1.1 has been modified for this study to include a maximum of 10 target lesions and a maximum of 5 target lesions per organ. |
| Recurrence-free survival (RFS) | Up to ~60 months | RFS is defined as the time from the date of surgery to (1) any recurrence (local, regional, or distant) as assessed by the investigator or (2) death due to any cause (both cancer and noncancer causes of death). Assessments are according to RECIST 1.1 which has been modified for this study to include a maximum of 10 target lesions and a maximum of 5 target lesions per organ. |
