Reconsidering palliative radiotherapy in addition to PD-1 blockade for non-small cell lung cancer: results from the FORCE phase II trial (AIO/YMO-TRK-0415).

ABSTRACT: Introduction of immune checkpoint inhibitors (ICI) has improved overall survival (OS) for advanced non-small cell lung cancer (NSCLC). However, responses differ greatly amongst patients. Additional radiotherapy (RT) may promote tumor-specific immunity and synergize with ICI to improve tumor control. The multicenter phase II FORCE trial evaluated safety and efficacy of nivolumab with additional palliative radiotherapy (5 × 4 Gy) as clinically indicated in pre-treated metastatic non-squamous NSCLC (group A, n = 41), including pretreated patients without an indication for radiotherapy in a parallel cohort as real-world controls (group B, n = 60). With an objective response rate (ORR) of 8.3% in group A (n = 41), the primary endpoint was not met (p = 0.991). ORR in group B (n = 60) was 23.8%.
