Phase 3 Study of Pembrolizumab With or Without Sacituzumab Tirumotecan After Surgery in Adults With Resectable Stage II to IIIB Non-Small Cell Lung Cancer Not Fully Responding to Pre-Surgery Treatment

What this Trial Is About

Researchers are evaluating whether adding sacituzumab tirumotecan to pembrolizumab after surgery improves treatment outcomes for adults with resectable non-small cell lung cancer NSCLC who do not achieve a complete response after initial therapy. This Phase 3 trial compares the combination of sacituzumab tirumotecan plus pembrolizumab against pembrolizumab alone, focusing on disease-free survival assessed by a blinded independent central review. The study is sponsored by Merck Sharp & Dohme LLC and targets participants with specific stages of NSCLC who have undergone neoadjuvant therapy and surgery but still have residual disease. Participants first receive neoadjuvant therapy consisting of pembrolizumab combined with double-platinum chemotherapy tailored to the tumor type for up to 12 weeks before surgery. After surgery, those not achieving pathological complete response are assigned to either receive sacituzumab tirumotecan infusions every two weeks for up to 24 weeks alongside pembrolizumab monotherapy every six weeks for approximately 42 weeks, or pembrolizumab monotherapy alone on the same schedule. Rescue medications to manage infusion reactions may be given as needed during the study. Throughout the trial, participants undergo assessments including radiological scans, tumor tissue analysis for markers like PD-L1 and TROP2, and monitoring for adverse events and quality of life changes. Key outcomes include disease-free survival, overall survival, distant metastasis-free survival, and lung cancer-specific survival, with evaluations continuing for up to nearly 10 years. Safety and tolerability are closely monitored, and questionnaires assess physical functioning, symptoms like cough and chest pain, and overall health status during and after treatment.
