Non Small Cell Lung Cancer | Drug: Gotistobart Drug: Docetaxel | Phase 3 |
This is a seamless 2-stage, randomized, open-label, active-controlled, Phase 3 study. The study population consists of patients with NSCLC who progressed on PD-1/PD-L1 inhibitor. Approximately 600 patients will be enrolled.
Two gotistobart dosing regimens will be tested in Stage I, and one will be selected for Stage II.
Stage I, the dose-confirmation stage, will assess the efficacy and safety of two gotistobart dosing regimens (3 mg/kg Q3W and 6 mg/kg Q3W with 2 loading doses of 10 mg/kg Q3W) in comparison to docetaxel 75 mg/m2 Q3W.
Stage II will assess the safety and efficacy of gotistobart at the selected dosing regimen versus docetaxel. Patients will be randomized 1:1 to receive either gotistobart at the selected dosing regimen or docetaxel.

- Overall Survival (OS) [ Time Frame: 36 months ]OS is defined as the time from randomization to the date of death by any cause. Kaplan-Meier estimates of median OS time will be presented by treatment arm with two sided 95% CIs.
- Objective response rate (ORR) [ Time Frame: 36 months ]Objective response rate (ORR) as assessed by Blinded Independent Central Review (BICR) per RECIST 1.1
- Progression-free survival (PFS) [ Time Frame: 36 months ]Progression-free survival (PFS) as assessed by Investigator per RECIST 1.1
- Treatment emergent adverse events, treatment related adverse events and immune related adverse events. [ Time Frame: 36 months ]Incidence of TEAEs, TRAEs, irAEs will be calcuated. The AEs leading to treatment discontinuation will be recorded.
