Is there any place for PD-1/CTLA-4 inhibitors combination in the first-line treatment of advanced NSCLC?-a trial-level meta-analysis in PD-L1 selected subgroups.

ABSTRACT:

Background

The advent of immuno-oncology (IO) represented a breakthrough in non-small cell lung cancer (NSCLC) therapy over the last few years. However, establishing the optimal therapeutic options among programmed death-ligand 1 (PD-L1) selected subgroups still addresses an unmet need in the clinical setting.

Methods

We performed a systematic review and finally included eleven first-line randomized controlled trials to compare efficacy and safety outcomes among first-line IO treatment strategies versus standard platinum-based chemotherapy (CT) according to PD-L1 expression level (<1%, 1-49%, ≥50%). Pooled hazard ratios (HRs) and risk ratios (RRs) for progression-free survival (PFS), overall survival (OS), objective response rates (ORR), treatment-related adverse events (TRA
