Aim: We report results from a randomized, open-label, phase 3 study comparing nivolumab vs docetaxel in patients with previously treated squamous NSCLC and disease progression during/after 1 prior platinum-doublet chemotherapy regimen.

Methods: Patients (N=272) were randomized 1:1 to nivolumab 3 mg/kg Q2W (n=135) or docetaxel 75 mg/m2 Q3W (n=137) until disease progression or discontinuation due to toxicity/other reasons. For nivolumab patients, treatment after initial progression was permitted at the investigator’s discretion, per protocol. Primary objective was overall survival (OS). Secondary objectives included investigator-assessed overall response rate (ORR; per RECIST v1.1), progression-free survival (PFS), efficacy by programmed death ligand-1 (PD-L1) expression (PD-L1 testing not required for enrollment), patient-reported outcomes, and safety.

Results: Nivolumab led to 41% reduction in risk of death (hazard ratio [HR]=0.59; 95% CI: 0.44, 0.79; P=0.00025) and improved ORR (20% vs 9%; P=0.0083) and PFS (HR=0.62; 95% CI: 0.47, 0.81; P=0.0004) vs docetaxel. Twenty-eight patients were treated with nivolumab beyond initial progression; 9 demonstrated non-conventional patterns of benefit (ie, reduction in target lesions with simultaneous appearance of new lesions, initial progression followed by tumor reduction, or no further progression for ≥2 tumor assessments). Tumor PD-L1 expression of 1%, 5%, or 10% was neither prognostic nor predictive of benefit. OS HRs favored nivolumab across most predefined patient subgroups; 7% (9/131) of nivolumab and 55% (71/129) of docetaxel patients experienced grade 3–4 drug-related adverse events (AEs). No deaths were related to nivolumab vs 3 docetaxel-related deaths.

Conclusions: CheckMate 017 achieved its primary objective, with nivolumab demonstrating clinically superior and statistically significant OS vs docetaxel in patients with advanced, previously treated, squamous NSCLC. Benefit was seen regardless of PD-L1 status. The safety profile of nivolumab is favorable vs docetaxel and consistent with prior studies. AEs were manageable with established guidelines. Nivolumab represents a new standard of care in these patients.
