Efficacy and Safety of SYHX2011 Combined with Carboplatin and Enlonstobart versus Nab-Paclitaxel Combined with Carboplatin and Tislelizumab as First-Line Treatment for Squamous Non-Small Cell Lung Cancer

Подробное описание

This is a multicenter, open-Label, phase II/III study in patients with squamous non-small cell lung cancer. Phase II will adopt a single-arm study design. The first 12 enrolled patients will be designated as the safety run-in cohort. Upon completion of safety observation after the first dose administration, the recommended dose will be selected for the expansion phase based on the safety and efficacy outcomes of the safety run-in phase.If the Phase II study results demonstrate that the combination therapy at the recommended dose is tolerable and has a favorable safety profile in trial participants, with preliminary evidence of anti-tumor activity, the investigators will determine whether to initiate the Phase III study. The current guideline-recommended first-line treatment regimen is planned to be selected as the control arm, and a randomized, controlled, open-label study design will be adopted. Participants will receive the study regimen (experimental arm) or the control regimen in accordance with the randomization results.
