Abstract

Despite the improved survival rates with consolidation PD-1/PD-L1 inhibitors after CRT, patients still experience disease recurrence. To date, there is no reported data about the efficacy of subsequent treatments, including re-treatment with checkpoint inhibitors, at the time of progression in this patient population. HCRN LUN 14-179 was a phase II, single-arm, multi-center trial which enrolled patients with stage III NSCLC who had received CRT (cisplatin/pemetrexed, carboplatin/paclitaxel, or cisplatin/etoposide + range 59.4 Gy to 66.6 Gy) of 92 total patients. A total of 37 (40%) participants developed progressive disease. Of those, 24 went on to receive subsequent therapy. 19/24 received chemotherapy only with response rates similar to those reported in a similar population of patients with stage IV disease. 6/24 were re-trialed with immunotherapy at some point [1]. Of those receiving subsequent immunotherapy, 5/6 had progressive disease as their best response; however, a patient receiving 2nd line Pembrolizumab achieved a partial response. Re-challenging patients with a PD-1 inhibitor may be reasonable to consider if the patient had disease progression after completing 1 year of consolidation immunotherapy.
