The Efficacy and Safety of Iparomlimab/Tuvonralimab (Anti PD-1/CTLA-4) Combined With Albumin-bound Paclitaxel in Second-line Treatment of Patients With Advanced Gastric/Gastroesophageal Junction Adenocarcinoma

The goal of this clinical trial is to evaluate the efficacy and safety of Iparomlimab and Tuvonralimab (anti PD-1/CTLA-4) combined with albumin-paclitaxel in the second-line treatment of patients with advanced gastric/gastroesophageal junction adenocarcinoma. The main questions it aims to answer are: 1. Can the combination of Iparomlimab/Tuvonralimab and albumin-paclitaxel for advanced gastric cancer/gastroesophageal junction cancer who has progressed or is intolerant to first-line SOC prolong the PFS and OS, improve ORR, DCR, and prolong DoR; 2. Whether Iparomlimab/Tuvonralimab ( anti PD-1/CTLA-4) combined with albumin-paclitaxel for second-line treatment remains effective for patients who have progressed from first-line PD-1±chemotherapy; 3. The safety and tolerability of Iparomlimab/Tuvonralimab in combination with albumin-paclitaxel for second-line treatment.Participants will:1. Use Iparomlimab/Tuvonralimab 5.0mg/kg, D1, Q3W; At least 30 minutes later, administer the chemotherapy albumin-paclitaxel: 260mg/m², D1, Q3W, and complete the infusion within 30 minutes. The combined regimen was administered every 3 weeks, with efficacy evaluated every 2 cycles (RECIST 1.1) until disease progression, intolerable toxicity or patient withdrawal.
