Trial Outcomes & Findings for Phase IIB TL + YCWP + DC in Melanoma (NCT NCT02301611)

NCT ID: NCT02301611

Last Updated: 2024-11-29

Results Overview

The primary outcome measure of the trial is assessing disease free survival (DFS) at 24 months compared between the vaccinated and control groups after the final enrolled patient completes two years of follow-up. An interim analysis will be performed six months after the final patient is enrolled. This analysis will compare median DFS between vaccinated and control groups.

Participant Flow

Patients 18 years of age or older with stage III/IV melanoma capable of being disease free after surgery were recruited at the individual study sites. Enrollment start was January 2015. Patients were first randomized 2:1 to receive either the TLPLDC vaccine or placebo (n=124), and then randomization transitioned to 2:1 TLPO or TLPLDC vaccine for 63 more patients. This resulted placebo (n=41), TLPO (n=43), and TLPLDC (n=103) formulations.
