Efficacy and Safety of Fruquintinib in Combination With PD-1 Inhibitors as First-line Maintenance Therapy for Advanced HER-2 Negative Gastric Cancer: a Single-arm, Prospective, Exploratory Clinical Study

Maintenance therapy is very important in advanced HER-2 negative gastric cancer, and immune monotherapy has no obvious benefit in the first-line maintenance treatment of advanced gastric cancer； Fruquintinib is a potent small-molecule VEGFR inhibitor with high kinase selectivity；Studies have shown that immunotherapy combined with antiangiogenic agents is promising for synergistic antitumor effects； The aim of this study was to observe and evaluate the efficacy and safety of Fruquintinib combined with PD-1 inhibitor in the first-line maintenance treatment of advanced HER-2 negative gastric cancer.

Experimental: Experimental; Fruquintinib+PD-1

Drug: Fruquintinib+PD-1; This is a one-arm, prospective, exploratory clinical study, including patients with advanced HER-2-negative gastric cancer (including gastroesophageal junction adenocarcinoma) who received first-line immunization combined with standard chemotherapy (RECIST 1.1 criteria) and were treated with fruquintinib（4mg orally, once daily for 3 wks on/1 wk off ）combined with PD-1 antibody.
