Methods: This adaptive phase 3 trial (NCT03631706) compared the efficacy and safety of bintrafusp alfa versus pembrolizumab as first-line treatment in patients with PD-L1-high advanced NSCLC. Primary end points were progression-free survival according to Response Evaluation Criteria in Solid Tumors version 1.1 per independent review committee and overall survival. Results: Patients (N = 304) were randomized one-to-one to receive either bintrafusp alfa or pembrolizumab (n = 152 each). The median follow-up was 14.3 months (95% confidence interval [CI]: 13.1-16.0 mo) for bintrafusp alfa and 14.5 months (95% CI: 13.1-15.9 mo) for pem-brolizumab. Progression-free survival by independent re-view committee was not significantly different between bintrafusp alfa and pembrolizumab arms (median = 7.0 mo [95% CI: 4.2 mo-not reached (NR)] versus 11.1 mo [95% CI: 8.1 mo-NR]; hazard ratio = 1.232 [95% CI: 0.885- 1.714]). The median overall survival was 21.1 months (95% CI: 21.1 mo-NR) for bintrafusp alfa and 22.1 months (95% CI: 20.4 mo-NR) for pembrolizumab (hazard ratio = 1.201 [95% CI: 0.796-1.811]). Treatment-related adverse events were higher with bintrafusp alfa versus pembrolizumab; grade 3-4 treatment-related adverse events occurred in 42.4% versus 13.2% of patients, respectively. The study was discontinued at an interim analysis as it was unlikely to meet the primary end point. Conclusions: First-line treatment with bintrafusp alfa did not exhibit superior efficacy compared with pembrolizumab in patients with PD-L1-high, advanced NSCLC.(c) 2023 International Association for the Study of Lung Cancer.
