- Immunotherapy with checkpoint inhibitors such as nivolumab has shown superior efficacy compared to docetaxel chemotherapy in previously treated advanced non-small cell lung cancer (NSCLC) based on results from randomized clinical trials.
- In the CheckMate 017 trial of pretreated squamous NSCLC, nivolumab demonstrated a median progression-free survival of 3.5 months compared to 2.8 months for docetaxel, as well as improved 1-year progression-free survival rates.
- These results established nivolumab and other immune checkpoint inhibitors as new standard treatment options for patients with advanced NSCLC who have progressed on previous chemotherapy.
