Multi‐institutional, prospective, randomized, double‐blind, placebo‐controlled phase IIb trial of the tumor lysate, particle‐loaded, dendritic cell (TLPLDC) vaccine to prevent recurrence in high‐risk melanoma patients: A subgroup analysis

Abstract

Checkpoint inhibitors (CPI) in combination with cell‐based vaccines may produce synergistic antitumor immunity. The primary analysis of the randomized and blinded phase IIb trial in resected stage III/IV melanoma demonstrated TLPLDC is safe and improved 24‐month disease‐free survival (DFS) in the per treatment (PT) analysis. Here, we examine efficacy within pre‐specified and exploratory subgroups.
