A Study of Intratumoral/Intralesional Administration of V938 in Combination With Pembrolizumab (MK-3475) in Participants With Advanced/Metastatic or Recurrent Malignancies (V938-001)
Study Details
Study Description
Brief Summary
The purpose of this study is to evaluate the safety, efficacy, pharmacokinetics, and V938 shedding in participants with advanced/metastatic or recurrent malignancies who receive V938 in combination with pembrolizumab (MK-3475). The primary objective is to determine the safety and tolerability and to identify a recommended Phase 2 dose (RP2D) of V938 administered in combination with pembrolizumab.

Phase 1 |
Detailed Description
Due to discontinuation of V938-001, all ongoing participants who completed V938 plus pembrolizumab treatment may be enrolled in an extension study (KN587) to continue pembrolizumab monotherapy for a total of 35 cycles since the first dose in V938-001 and to be monitored as appropriate.

Outcome Measures
Primary Outcome Measures
- Number of Participants Who Experience Dose-Limiting Toxicity (DLT) [Up to 42 days]
The number of participants experiencing toxicities that are possibly, probably, or definitely related to study intervention administration will be reported.
- Number of Participants Who Experience ≥1 Adverse Event (AE) [Up to approximately 28 months]
The number of participants who experience ≥1 adverse event will be reported.
- Number of Participants Who Discontinue Study Drug Due to an Adverse Event (AE) [Up to approximately 25 months]
The number of participants who discontinue study drug due to an adverse event will be reported.
Secondary Outcome Measures
- Objective Response Rate (ORR) [Up to approximately 5 years]
ORR is defined as the percentage of participants who have a Complete Response (CR: Disappearance of all target lesions) or a Partial Response (PR: At least a 30% decrease in the sum of diameters of target lesions), as assessed by the investigator. In solid tumors, assessment will be based on Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) and modified RECIST 1.1 for immune-based therapeutics (iRECIST). The percentage of participants who experience a CR or PR based on the above criteria will be presented.
- Area Under the Concentration-Time Curve from 0 to Infinity (AUC0-inf) for V938 Ribonucleic Acid (RNA) in Plasma [Predose cycle 1 on 4 separate days, cycles 2, 3, 5, 8, 9, and 10 on day 1. 2, 4, and 6 hours postdose cycle 1 on 2 separate days, and cycle 2 on day 1. 2 to 4 hours postdose cycle 3 on day 1. 30 days after last dose. Each cycle is 21 days.]
The AUC0-inf for V938 RNA in plasma will be calculated.
- Maximum Concentration (Cmax) of V938 Ribonucleic Acid (RNA) Reached in Plasma [Predose cycle 1 on 4 separate days, cycles 2, 3, 5, 8, 9, and 10 on day 1. 2, 4, and 6 hours postdose cycle 1 on 2 separate days, and cycle 2 on day 1. 2 to 4 hours postdose cycle 3 on day 1. 30 days after last dose. Each cycle is 21 days.]
The Cmax for V938 RNA in plasma will be reported.
- V938 Excretion: Polymerase Chain Reaction (PCR) [Predose cycle 1 on 3 separate days, and cycles 3, 5, 8, 9, and 10 on day 1. 2 and 4-6 hours postdose cycle 1 day 1. Each cycle is 21 days.]
The presence of V938, determined by PCR, in oral cavity/throat, urine, injection site, and anus will be reported.
- V938 Excretion: Infectivity [Predose cycle 1 on 3 separate days, and cycles 3, 5, 8, 9, and 10 on day 1. 2 and 4-6 hours postdose cycle 1 day 1. Each cycle is 21 days.]
The presence of V938, determined by infectivity of V938, in oral cavity/throat, urine, injection site, and anus will be reported.
