Pembrolizumab With or Without Maintenance Sacituzumab Tirumotecan (Sac-TMT; MK-2870) in Metastatic Squamous Non-small Cell Lung Cancer (NSCLC) [MK-2870-023]
Recruiting
This is a phase 3 study of pembrolizumab in combination with carboplatin/taxane (paclitaxel or nab-paclitaxel) followed by pembrolizumab with or without maintenance sacituzumab tirumotecan (sac-TMT; MK-2870) in first-line treatment of metastatic squamous non-small cell lung cancer. It is hypothesized that pembrolizumab with maintenance sacituzumab tirumotecan is superior to pembrolizumab without sacituzumab tirumotecan maintenance with respect to overall survival (OS).
