Abstract:
There is currently no standard treatment strategy for patients with advanced metastatic gastric cancer experiencing progression after two or more lines of chemotherapy. We assessed the efficacy and safety of apatinib, a novel vascular endothelial growth factor receptor 2 tyrosine kinase inhibitor, in patients with advanced gastric or gastroesophageal junction adenocarcinoma for whom at least two lines of prior chemotherapy had failed. Patients and Methods This was a randomized, double-blind, placebo-controlled phase III trial. Patients from 32 centers in China with advanced gastric or gastroesophageal junction adenocarcinoma, for whom two or more prior lines of chemotherapy had failed, were enrolled. Patients were randomly assigned to oral apatinib 850 mg or placebo once daily. The primary end points were overall (OS) and progression-free survival (PFS). Results Between January 2011 and November 2012, 267 patients were enrolled. Median OS was significantly improved in the apatinib group compared with the placebo group (6.5 months; 95% CI, 4.8 to 7.6 v 4.7 months; 95% CI, 3.6 to 5.4; P = .0149; hazard ratio, 0.709; 95% CI, 0.537 to 0.937; P = .0156). Similarly, apatinib significantly prolonged median PFS compared with placebo (2.6 months; 95% CI, 2.0 to 2.9 v 1.8 months; 95% CI, 1.4 to 1.9; P 〈 .001; hazard ratio, 0.444; 95% CI, 0.331 to 0.595; P 〈 .001). The most common grade 3 to 4 nonhematologic adverse events were hand-foot syndrome, proteinuria, and hypertension. Conclusion These data show that apatinib treatment significantly improved OS and PFS with an acceptable safety profile in patients with advanced gastric cancer refractory to two or more lines of prior chemotherapy.
