Participants received daily oral encorafenib (450mg) and twice daily oral binimetinib (90mg total). Primary endpoints were dose-limiting toxicities (DLT) during SLI and confirmed objective response rate by independent central review (cORR-ICR) during PP. Secondary endpoints were other measures of efficacy, safety, and pharmacokinetics.\n\nResults: In total, 63 participants were enrolled. One DLT (non-serious Grade 3 lipase increased) during SLI considered possibly related to E+B resolved without intervention, supporting initiation of PP. Pre-defined statistical efficacy criteria on the first 50 participants were met. In the main analysis, cORR-ICRwas59% (95%CI 45-72). At a later ad hoc analysis, cORR-ICR was 61% (95%CI 47-74), disease control rate 87% (95%CI 75-95). Medians (95%CI) were, time-to-response 1.8 months, duration of response 17.5 months, progression-free survival 13.8 months (7.5-not estimable), overall survival 27.9 months (14.7-30.0). 98.4% of participants experienced ≥1 treatment-related TEAE, and 55.6% had any Grade ≥3 TEAE. Nine (14.3%) participants discontinued any drug due to adverse events.\n\nConclusion: These data confirm the clinical benefit of E+B in Chinese participants with BRAF V600E -mNSCLC, a population with distinct genomic and disease characteristics. No new safety concerns were identified in Chinese participants.\n\nIndexed on Europe PMC as PubMed record 42612509 (DOI 10.1016/j.lungcan.2026.109580).
