Brief Summary

This study is a prospective, randomized, non-controlled, open-label clinical trial aimed at evaluating the efficacy and safety of adebrelimab combined with apatinib mesylate and albumin-bound paclitaxel, as well as apatinib mesylate combined with albumin-bound paclitaxel, in treating advanced second-line gastric adenocarcinoma or gastroesophageal junction adenocarcinoma. The study's primary endpoint is median progression-free survival (mPFS), and it plans to enroll 50 patients with gastric adenocarcinoma or gastroesophageal junction adenocarcinoma who failed first-line systemic therapy. This is a randomized, non-controlled, open-label trial. Eligible participants will be randomly assigned in a 1:1 ratio to receive either adebrelimab combined with apatinib mesylate and albumin-bound paclitaxel (Cohort 1) or apatinib mesylate combined with albumin-bound paclitaxel (Cohort 2). The screening phase is 28 days. After completing screening tests and assessments, eligible participants will be randomly assigned to the following treatments: Cohort 1:

• Adebrelimab: 1200 mg, IV infusion, once every 21 days, until PD or intolerance, maximum use 2 years;
• Apatinib mesylate: 250 mg, orally, once daily, days 1-21; until PD or intolerance, maximum use 2 years;
• Albumin-bound paclitaxel: 200-260 mg/m², IV infusion, day 1, once every 21 days, for 4-6 cycles. Cohort 2:
• Apatinib mesylate: 250 mg, orally, once daily, days 1-21; until PD or intolerance, maximum use 2 years;
• Albumin-bound paclitaxel: 200-260 mg/m², IV infusion, day 1, once every 21 days, for 4-6 cycles.
