Abstract
TPS10079
Background: Treatment options are limited for patients with advanced metastatic or unresectable melanoma, especially after anti-PD-1 failure. T-VEC is an intralesional oncolytic viral immunotherapy designed to selectively replicate in tumor cells and induce local and systemic antitumor response. Pembro promotes T cell activity by blocking PD-1 receptors. Combining T-VEC and pembro may produce robust antitumor activity by increasing T cell activation and blocking T cell inhibition, with a tolerable safety profile. The MASTERKEY-115 trial will evaluate safety and efficacy of T-VEC combined with pembro in patients with advanced melanoma who experienced progressive disease (PD) on prior anti-PD-1 therapy. Methods: NCT04068181 is a phase 2, open-label, single-arm, multicenter trial of T-VEC with pembro in patients with advanced melanoma and PD on prior anti-PD-1. The study is expected to enroll approximately 100 patients and comprises 4 cohorts. Cohorts 1 and 2 will receive anti-PD-1 in a locally recurrent or metastatic setting and experienced PD within 12 weeks of the last anti-PD-1 dose (Cohort 1: PD or stable disease prior to confirmed PD; Cohort 2: complete or partial response prior to confirmed PD). Cohorts 3 and 4 will receive adjuvant anti-PD-1 and were disease-free for < 6 months (Cohort 3) or ≥ 6 months (Cohort 4) prior to confirmed PD. Enrollment criteria include adults with histologically confirmed unresectable or metastatic stage IIIB–IVM1d melanoma, measurable and injectable disease, ECOG PS 0-1, and prior anti-PD-1 (≥ 2-3 consecutive cycles within 8 weeks, immediate prior treatment before enrollment). The primary endpoint is objective response rate per modified RECIST. Key secondary endpoints assess efficacy (objective response rate, best overall response, complete response rate, response duration, durable response rate, disease control rate, progression-free survival, overall survival), safety (incidence of treatment-emergent and treatment-related adverse events, abnormal laboratory tests), and time to subsequent anticancer therapy. The study began enrolling patients in January 2020 and enrollment is ongoing. Clinical trial information: NCT04068181.
