The primary objectives of this control, single-center clinical study of EndostarTM Injection with/without SOX protocols to treat advanced gastric cancer were to evaluate the clinical response rate of Endostar injection concomitant with SOX on patients with advanced gastric cancer, observe the progression-free survival time (PFS) of tumor and evaluate the safety and tolerance of Endostar injection, while the secondary objectives were to observe the influence of Endostar injection on chemotherapy-induced adverse reactions and evaluate the overall survival time of EndostarTM injection concomitant with SOX on patients with advanced gastric cancer by evaluating the response rate (RR) clinical benefit rate (CBR), progression-free survival (PFS) and overall survival (OS).
