After more than 4 years of follow-up, median survival wasn't reached in the melanoma study.
Iovance Biotherapeutics (IOVA) announced that its lifileucel combined with pembrolizumab showed promising results in a Phase 2 trial for frontline advanced melanoma. The study reported a median progression-free survival of 19.8 months, with median overall survival not reached at over 4 years. The company is conducting a Phase 3 trial (TILVANCE-301) to support potential approval for this combination therapy. Iovance estimates a global market of 70,000 patients annually for this indication.
