IIntroduction: In the JAVELIN Lung 200 trial, avelumab (anti-programmed death-ligand 1 [PD-L1] antibody) did not significantly prolong overall survival (OS) versus docetaxel in patients with platinum-treated PD-L1+ NSCLC. We report greater than 2-year follow-up data. Methods: Patients with stage IIIB or IV or recurrent NSCLC with disease progression after platinum-doublet chemotherapy were randomized 1:1 to avelumab 10 mg/kg every 2 weeks or docetaxel 75 mg/m2 every 3 weeks. The primary end point was OS in patients with PD-L1+ tumors (greater than or equal to 1% tumor cell expression; IHC 73-10 pharmDx assay). Results: Of 792 patients, 529 had PD-L1+ tumors (264 versus 265 in the avelumab versus docetaxel arms, respectively). As of March 4, 2019, median duration of follow-up for OS in the PD-L1+ population was 35.4 months in the avelumab arm and 34.7 months in the docetaxel arm; study treatment was ongoing in 25 (9.5%) versus 0 patients, respectively. In the PD-L1+ population, 2-year OS rates (95% confidence interval [CI]) with avelumab versus docetaxel were 29.9% (24.5%–35.5%) versus 20.5% (15.6%–25.8%); in greater than or equal to 50% PD-L1+ subgroups, 2-year OS rates were 36.4% (29.1%–43.7%) versus 17.7% (11.8%–24.7%) and in the greater than or equal to 80% subgroup were 40.2% (31.3%–49.0%) versus 20.3% (12.9%–28.8%), respectively. Median duration of response (investigator assessed) was 19.1 months (95% CI: 10.8–34.8) versus 5.7 months (95% CI: 4.1–8.3). Safety profiles for both arms were consistent with the primary analysis. Conclusions: Although the JAVELIN Lung 200 primary analysis (reported previously) revealed that avelumab did not significantly prolong OS versus docetaxel in patients with platinum-treated PD-L1+ NSCLC, posthoc analyses at 2 years of follow-up revealed that 2-year OS rates were doubled with avelumab in subgroups with higher PD-L1 expression (greater than or equal to 50% and greater than or equal to 80%).

Abstract

IIntroduction: In the JAVELIN Lung 200 trial, avelumab (anti-programmed death-ligand 1 [PD-L1] antibody) did not significantly prolong overall survival (OS) versus docetaxel in patients with platinum-treated PD-L1+ NSCLC. We report greater than 2-year follow-up data. Methods: Patients with stage IIIB or IV or recurrent NSCLC with disease progression after platinum-doublet chemotherapy were randomized 1:1 to avelumab 10 mg/kg every 2 weeks or docetaxel 75 mg/m2 every 3 weeks. The primary end point was OS in patients with PD-L1+ tumors (greater than or equal to 1% tumor cell expression; IHC 73-10 pharmDx assay). Results: Of 792 patients, 529 had PD-L1+ tumors (264 versus 265 in the avelumab versus docetaxel arms, respectively). As of March 4, 2019, median duration of follow-up for OS in the PD-L1+ population was 35.4 months in the avelumab arm and 34.7 months in the docetaxel arm; study treatment was ongoing in 25 (9.5%) versus 0 patients, respectively. In the PD-L1+ population, 2-year OS rates (95% confidence interval [CI]) with avelumab versus docetaxel were 29.9% (24.5%–35.5%) versus 20.5% (15.6%–25.8%); in greater than or equal to 50% PD-L1+ subgroups, 2-year OS rates were 36.4% (29.1%–43.7%) versus 17.7% (11.8%–24.7%) and in the greater than or equal to 80% subgroup were 40.2% (31.3%–49.0%) versus 20.3% (12.9%–28.8%), respectively.
