Durvalumab/Tremelimumab Combo Could Be Useful in First-Line Treatment for NSCLC

“A combination of the anti–PD-L1 immune checkpoint inhibitor durvalumab (MEDI4736) with the anti–CTLA-4 monoclonal antibody tremelimumab showed improved tumor response in patients with advanced non–small cell lung cancer (NSCLC) over single-agent therapy.

“The study, published in the Journal for ImmunoTherapy of Cancer, was a phase I, open-label, dose-escalation/expansion study that contained 84 patients. Of these patients, 48 had two or more prior lines of therapy. Data from the study showed improved tumor response regardless of PD-L1 status, with an overall response rate of 25% and 35% of PD-L1-negative patients receiving a response (0% tumor cell staining).”
