NCT Number NCT06179069  Clinical Status PHASE1
Clinical Description
An Open-label, Multicenter Study of ZL-1310 to Evaluate the Safety, Tolerability, and Pharmacokinetics in Subjects With Small Cell Lung Cancer
Primary Endpoint
Safety endpoints include incidence of Dose Limiting Toxicities (DLTs), Treatment-Emergent Adverse Events (TEAEs), and Serious Adverse Events (SAEs) for ZL-1310 as monotherapy and in combination with atezolizumab ± carboplatin, all assessed over 24 months. DLTs will be evaluated separately for each treatment regimen (monotherapy, doublet, and triplet combinations), with corresponding counts of affected subjects recorded for each safety parameter.

Other Endpoint
Efficacy measures comprise ORR, DOR, PFS, DCR (all per RECIST 1.1), and OS for all three treatment regimens (monotherapy, doublet, triplet), evaluated over 24 months. Pharmacokinetic analyses include total antibody and unconjugated payload measurements for each treatment combination, with assessments continuing through the 24-month study period.
