Overview
Brief Summary
This is a phase II study to evaluate the efficacy and safety of combination of fruquintinib (VEGFR 1/2/3 inhibitor), sintilimab (PD-1 inhibitor) and SOX conversion therapy in unresectable advanced gastric cancer patients.
Detailed Description
Eligible patients will be given 3 or 6 cycles of combined therapy of fruquintinib + sintilimab + SOX. Then the patients evaluated resectable will be given one additional cycle of combined treatment with sintilimab + SOX, followed by R0 resection. If evaluated unresectable after 6 cycles of combination therapy, the patient will be given palliative first-line treatment. Adjuvant treatment with SOX regimen will be started 4 weeks after R0 resection for a total of 8 cycles in the perioperative period.
