Five Year Survival Update From KEYNOTE-010: Pembrolizumab Versus Docetaxel for Previously Treated, Programmed Death-Ligand 1-Positive Advanced NSCLC
Introduction: In the KEYNOTE-010 study, pembrolizumab improved overall survival (OS) versus docetaxel in patients with previously treated, advanced NSCLC with programmed death-ligand 1 (PD-L1) tumor proportion score (TPS) >= 50% and >= 1%. We report 5-year efficacy and safety follow-up for the...

| Sumario: | Introduction: In the KEYNOTE-010 study, pembrolizumab improved overall survival (OS) versus docetaxel in patients with previously treated, advanced NSCLC with programmed death-ligand 1 (PD-L1) tumor proportion score (TPS) >= 50% and >= 1%. We report 5-year efficacy and safety follow-up for the KEYNOTE-010 study. Methods: Patients were randomized to pembrolizumab 2 mg/kg or 10 mg/kg once every 3 weeks or docetaxel 75 mg/m(2) once every 3 weeks for up to 35 cycles (2 y). Patients who completed pembrolizumab treatment and subsequently had recurrence could receive second-course pembrolizumab for up to 17 cycles (1 y). Pembrolizumab doses were pooled in this analysis. Results: A total of 1034 patients were randomized (pembrolizumab, n = 691; docetaxel, n = 343). Median study follow-up was 67.4 months (range: 60.0-77.9). The hazard ratio (95% confidence interval) for OS was 0.55 (0.44. 0.69) for patients with PD-L1 TPS >= 50% and 0.70 (0.61. 0.80) with PD-L1 TPS >= 1%. The 5-year OS rates for pembrolizumab versus docetaxel were 25.0% versus 8.2% in patients with PD-L1 TPS >= 50% and 15.6% versus 6.5% with PD-L1 TPS >= 1%. Among 79 patients who completed 35 cycles/2 years of pembrolizumab, the OS rate 3 years after completion (similar to 5 y from randomization) was 83.0%. A total of 21 patients received second-course pembrolizumab; 11 (52.4%) had an objective response after starting the second course and 15 (71.4%) were alive at data cutoff. Exploratory biomarker analysis revealed that higher tissue tumor mutational burden (>= 175 mutations per exome) was associated with improved outcomes with pembrolizumab. Conclusions: Pembrolizumab continued to provide long-term benefit than docetaxel in patients with previously treated advanced NSCLC with PD-L1 TPS >= 50% and >= 1%. Our findings confirm pembrolizumab as a standard-of-care treatment in the second-line or later setting.
