A Randomized, Open-Label, Multi-center, Phase 3 Study Evaluating the Efficacy and Safety of IBI363 Versus Docetaxel in Participants With Unresectable Locally Advanced or Metastatic Squamous Non-Small Cell Lung Cancer With Disease Progression on or After Platinum-Based Chemotherapy and Anti-PD-1/PD-L1 Immunotherapy

Summary

Primary vs. acquired IO resistance 2. Concurrent vs. sequential prior chemo-immunotherapy 3. Region (Asia vs. non-Asia) Treatment Arms: 1. IBI363 Arm (Investigational Drug): Priming dose: 0.1 mg/kg on Day 1 of Cycle 1 (C1D1) Intended dose: 3 mg/kg every 3 weeks (Q3W) starting Day 8 of Cycle 1 (C1D8) Cycle duration: 28 days for Cycle 1, then 21 days from Cycle 2 onward Dose adjustments: Up to 2 reductions (1.5 mg/kg or 1 mg/kg Q3W) allowed for adverse events (AEs) Re-priming protocol: Required if delays in dosing exceed defined thresholds (e.g., \>10 days post-priming or ≥5 weeks since last dose) 2. Control Arm (Docetaxel): 75 mg/m² every 3 weeks (Q3W), starting from C1D1 21-day cycle duration Dose Reduction: as per label
