Brief Summary:
This is a Phase 2 study to assess the efficacy, safety, and tolerability of gebasaxturev administered both intratumorally (ITu) and intravenously (IV) as combination therapy with pembrolizumab (MK-3475) versus pembrolizumab alone in anti-programmed cell death ligand 1 (anti-PD-L1)-treatment-naive participants with advanced/metastatic melanoma. The primary hypothesis of the study is that gebasaxturev administered either ITu or IV in combination with pembrolizumab results in a superior objective response rate (ORR) per Response Evaluation Criteria In Solid Tumors Version 1.1 (RECIST 1.1) based on blinded independent central review (BICR), compared to pembrolizumab alone. This study will be terminated once all participants finish treatment with V937. Participants eligible to continue to receive pembrolizumab will be transferred to MK-3475-587 study.

Primary Outcome Measures :
- Objective Response Rate (ORR) per Response Evaluation Criteria In Solid Tumors Version 1.1 (RECIST 1.1) as Assessed by Blinded Independent Central Review (BICR) [ Time Frame: Up to 3 years ]ORR is defined as the percentage of participants who have a Complete Response (CR: disappearance of all lesions) or a Partial Response (PR: at least a 30% decrease in the sum of diameters of target lesions, without evidence of progression based on non-target or new lesions) as assessed by BICR per RECIST 1.1 which is modified for this study to follow a maximum of 10 target lesions and a maximum of 5 target lesions per organ. The percentage of participants who experience a CR or PR based on modified RECIST 1.1 will be presented.
Secondary Outcome Measures :
- Progression-free Survival (PFS) per RECIST 1.1 as Assessed by BICR [ Time Frame: Up to 3 years ]PFS is defined as the time from randomization to the first documented progressive disease (PD) or death due to any cause, whichever occurs first. Per RECIST 1.1, PD is defined as either a 20% increase from nadir in target lesions, unequivocal progression of non-target lesions, or the appearance of new lesions. PFS will be assessed by BICR for this outcome measure.
- Duration of Response (DOR) per RECIST 1.1 as Assessed by BICR [ Time Frame: Up to 3 years ]For participants who demonstrate a confirmed complete response (CR: disappearance of all lesions) or confirmed Partial Response (PR: at least a 30% decrease in the sum of diameters of target lesions, without evidence of progression based on non-target or new lesions.) per RECIST 1.1, DOR is defined as the time from first documented evidence of CR or PR until disease progression or death due to any cause, whichever occurs first. RECIST 1.1 has been modified for this study to follow a maximum of 10 target lesions and a maximum of 5 target lesions per organ, and will be assessed by BICR for this outcome measure.
- ORR per RECIST 1.1 as Assessed by the Investigator [ Time Frame: Up to 3 years ]ORR is defined as the percentage of participants who have a confirmed Complete Response (CR: disappearance of all lesions) or Partial Response (PR: at least a 30% decrease in the sum of diameters [SOD] of target lesions, without evidence of progression based on non-target or new lesions.) as assessed by the investigator per RECIST 1.1, which is modified for this study to follow a maximum of 10 target lesions and a maximum of 5 target lesions per organ. The percentage of participants who experience a CR or PR based on modified RECIST 1.1 will be presented.
- PFS per RECIST 1.1 as Assessed by the Investigator [ Time Frame: Up to 3 years ]PFS is defined as the time from randomization to the first documented progressive disease (PD) or death due to any cause, whichever occurs first. Per RECIST 1.1, PD is defined as either a 20% increase from nadir in target lesions, unequivocal progression of non-target lesions, or the appearance of new lesions. PFS will be assessed by the investigator for this outcome measure.
- DOR per RECIST 1.1 as Assessed by the Investigator [ Time Frame: Up to 3 years ]For participants who demonstrate a confirmed complete response (CR: disappearance of all lesions) or confirmed Partial Response (PR: at least a 30% decrease in the sum of diameters of target lesions) per RECIST 1.1, DOR is defined as the time from first documented evidence of CR or PR until disease progression or death. DOR will be assessed by the investigator for this outcome measure.
- Overall Survival (OS) [ Time Frame: Up to 3 years ]OS is defined as the time from the date of study treatment to the date of death due to any cause.
- Number of Participants with One or More Adverse Events (AEs) [ Time Frame: Up to 30 days after last dose (up to 3 years) ]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 at least one AE will be reported.
- Number of Participants who Discontinue Study Drug Due to an AE [ Time Frame: Up to 2 years ]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.
