Phase 3 Study Comparing PF-08634404 Plus Chemotherapy to Pembrolizumab Plus Chemotherapy for Adults With Advanced or Metastatic Non-Small Cell Lung Cancer

What this Trial Is About

Researchers are evaluating whether a new medicine called PF-08634404, given with chemotherapy, works better than the current standard treatment of pembrolizumab combined with chemotherapy for adults with a type of lung cancer known as non-small cell lung cancer NSCLC. This study focuses on participants with locally advanced or metastatic NSCLC who are not candidates for surgery or curative chemoradiotherapy and have no known actionable genomic alterations. The study is a Phase 3 randomized trial with double-blind masking to compare these treatments. Participants are assigned to one of two parts based on their tumor type those with squamous NSCLC are in Part 1, and those with non-squamous NSCLC are in Part 2. Each participant is randomly placed into one of two treatment groups the experimental group receives PF-08634404 plus chemotherapy, while the control group receives pembrolizumab plus chemotherapy. Treatments are given through intravenous infusions in cycles, followed by maintenance therapy with either PF-08634404 or pembrolizumab, depending on the part of the study. Participants continue treatment as long as it helps and side effects are manageable. During the study, participants attend regular visits for treatment and health assessments. Cancer response is checked every 6 weeks for the first 48 weeks and then every 12 weeks after that. Researchers monitor overall survival, progression-free survival, objective response rates, duration of response, adverse events, lab abnormalities, and quality of life measures. The study includes detailed tracking of drug levels and immune responses. Participation may last up to approximately 39 months, with continuous safety and effectiveness monitoring.
