Title: “Randomized phase I trial of adjuvant individualized TG4050 vaccine in patients with locally advanced resected HPV-negative head and neck squamous cell carcinoma (HNSCC)”.

TG4050 is an individualized immunotherapy being developed for solid tumors that is based on Transgene’s myvac® technology and powered by NEC’s longstanding artificial intelligence (AI) expertise. TG4050 is being evaluated in a randomized multicenter Phase I/II clinical trial as a single agent in the adjuvant treatment of HPV-negative head and neck cancers (NCT04183166).

Transgene previously presented data in April 2024, that showed that all patients who received TG4050 remained disease-free after a median follow-up of 18.6 months, comparing favorably to the observational arm which saw 3 out of 16 patients relapse during the same time period.

Transgene and NEC are continuing the joint development of TG4050 in this indication with a Phase II extension of the trial, which is currently enrolling patients.
