Arm 2: JS207 (10 mg/kg or 15 mg/kg, IV, D1) + Paclitaxel (175 mg/m2 IV, D1) + a platinum (carboplatin AUC 5, D1 or cisplatin 75 mg/m2, D1), Q3W, for 4 cycles followed by JS207 (10 mg/kg or 15 mg/kg, IV, D1), Q3W, until meeting the treatment withdrawal criteria.The study aims to assess the safety, tolerability, and preliminary efficacy of JS207 combination therapy.
