Primary analysis of the phase 2 LUMINOSITY trial (NCT03539536) revealed Teliso-V monotherapy 1.9 mg/kg elicited durable responses and had generally manageable safety in patients with locally advanced or metastatic c-Met protein overexpressing, EGFR wild-type, nonsquamous NSCLC. We present updated outcomes with approximately 6 months longer follow-up and explore the impact of previous therapies.\n\nMethods: Patients (≥18 y; had previous therapy including ≤1 chemotherapy) received 1.9 mg/kg Teliso-V every 2 weeks. c-Met protein overexpression (clinical trial assay for MET [SP44] [Roche]) was defined as greater than or equal to 25% tumor cells with 3+ staining intensity (c-Met high: ≥50% 3+; c-Met intermediate: 25 to <50% 3+). Primary end point was the overall response rate by independent central review per the Response Evaluation Criteria in Solid Tumors version 1.1.\n\nResults: at February 21, 2024, 172 patients received at least one dose of Teliso-V; 168 patients (c-Met high, n = 84; c-Met intermediate, n = 84) were evaluable for efficacy. The overall response rate was 29.2% (95% confidence interval [CI]: 22.4-36.7; c-Met high, 34.5% [24.5-45.7]; c-Met intermediate, 23.8% [15.2-34.3]). Median duration of response was 7.2 months (95% CI: 5.5-11.0; c-Met high, 7.2 [95% CI: 4.2-12.0]; c-Met intermediate, 7.2 [95% CI: 4.7-11.5]). Previous therapy (platinum, immune checkpoint inhibitors, or both) did not impact efficacy outcomes. The most common treatment-related adverse event was peripheral sensory neuropathy (any-grade: 31%; grade ≥3: 7%).\n\nConclusions: Teliso-V monotherapy 1.9 mg/kg elicited durable responses, irrespective of the type of previous therapy received, and maintained a manageable safety profile in patients with c-Met protein overexpressing EGFR wild-type, nonsquamous NSCLC.\n\nClinicaltrialsgov id number: NCT03539536.\n\nIndexed on Europe PMC as PubMed record 42368479 (DOI 10.1016/j.jtocrr.2026.100988).
