Brief Summary

Currently, standard treatment options for gastric cancer failed to first-line treatment include monotherapy with paclitaxel/irinotecan/docetaxel/albumin paclitaxel, or paclitaxel combined with ramucirumab. However, the efficacy of these regimens is still far from satisfactory. The aim of the study is to evaluate the efficacy and safety of nab-paclitaxel combined with cadonilimab for the second-line treatment of advanced gastric cancer.

Detailed Description

This trial is a prospective, multicenter, single arm, phase II clinical study. It is divided into three stages: screening period, treatment period, and follow-up period. The main research objective of this study is to evaluate the objective response rate (ORR) of albumin paclitaxel combined with kandelizumab (AK104) in second-line treatment of gastric cancer with failed first-line fluorouracil/platinum combination immunotherapy. Secondary study objective: To evaluate the disease control rate (DCR), progression free survival (PFS), overall survival (OS), safety, tolerability, and impact on patient quality of life (QoL) of albumin paclitaxel combined with candelizumab (AK104) in second-line treatment of gastric cancer with failed first-line fluorouracil/platinum immunotherapy.

3. Active autoimmune disease or history of refractory autoimmune disease.

4. Grade 3-4 immune hepatitis, immune pneumonia, immune myocarditis, etc. appear in first-line immunotherapy.

5. Receiving corticosteroids (>10mg/d prednisone or equivalent dose of steroids) or other systematic immunosuppression therapies within 14 days before enrollment, excluding the following therapies: steroid hormone replacement therapy (≤10mg/d); local steroid therapy; and short-term, prophylactic steroid therapy for preventing allergies or nausea and vomiting.
