Comparing Lifileucel plus Pembrolizumab with Pembrolizumab with Optional Crossover for metastatic melanoma
Official title: Study to Investigate Lifileucel Regimen Plus Pembrolizumab Compared With Pembrolizumab Alone in Participants With Untreated Advanced Melanoma.
A Phase 3, Multicenter, Randomized, Open-label, Parallel Group, Treatment Study to Assess the Efficacy and Safety of the Lifileucel (LN-144, Autologous Tumor Infiltrating Lymphocytes [TIL]) Regimen in Combination With Pembrolizumab Compared With Pembrolizumab Monotherapy in Participants With Untreated, Unresectable or Metastatic Melanoma
Interventions
Lifileucel plus Pembrolizumab
A tumor sample is resected from each patient for Lifileucel manufacturing. Patients then receive Pembrolizumab followed by the lifileucel regimen which consists of non-myeloablative lymphodepletion, lifileucel infusion followed by IL-2. Patients will then continue to receive Pembrolizumab every 6 weeks until disease progression.
Pembrolizumab with Optional Crossover Period
Patient will receive Pembrolizumab monotherapy every 6 weeks until disease progression. Upon verified confirmed disease progression by the blinded independent review central committee, patients may proceed to lifileucel monotherapy during an optional crossover period if they meet eligibility criteria. Optional crossover: A tumor sample is resected from each patient for Lifileucel manufacturing. Patients then receive the lifileucel regimen which consists of non-myeloablative lymphodepletion, lifileucel infusion followed by IL-2.

About This Trial
This is a Phase 3, multicenter, open-label, randomized, parallel group, treatment study to assess the efficacy and safety of lifileucel in combination with pembrolizumab compared with pembrolizumab alone in participants with untreated, unresectable or metastatic melanoma. Participants randomized to the pembrolizumab monotherapy arm who subsequently have a blinded independent central review- verified confirmed progressive disease (PD) will be offered lifileucel monotherapy in an optional crossover period.
