Clinical Trial Summary

Gastric cancer is the one of the leading cause of cancer death in the worldwide. Gastric cancer originates from the most superficial mucosal epithelial cells of the stomach wall, which can occur in various parts of the stomach, and can invade different depths and breadth of the gastric wall. Without chemotherapy treatment the GC patients' Median Survival Time (MST) lasts only 3-4 months. Although treated with multi-chemotherapy MST has been improved, the drugs show strong toxicities in the patients. Thus the more accurate, lower toxicity, targeted antitumor drugs are put into second-line treatment program for advanced gastric cancer.

Apatinib, a novel targeted inhibitor of VEGF receptor 2 (VEGFR2), shows significant antitumor activity in the patients with GC. The purpose of this study is to determine whether apatinib plus capecitatine can improve progression free survival in patients with advanced gastric cancer.

Only second-line gastric cancer patients in late phase and at least one month interval from the latest chemotherapy treatment; 4. Previous treatment program without apatinib or capecitabine or any other antiangiogenic medications; 5. Subjects with at least one measurable lesion (defined by RECIST ,version 1.1), which is confirmed by computed tomography (CT) scan or MRI=10mm .

6. Eastern Cooperative Oncology Group (ECOG) performance status of 0-2 7. Survival expectation= 3 months; 8. Subjects were recovered from damages caused by other treatments, with the interval = 6 weeks for the treatment of the Nitro or Mitomycin, and 4 weeks for other cytotoxic drugs, radiotherapy or surgery, and the wound is completely healed 9. Subjects without severe heart, lung or liver dysfunction, no jaundice and digestive tract obstruction, and acute infection associated 10. The main organs function normally, and meet the following standards:

Intervention

Drug:
• Apatinib/Capecitatine
Apatinib is a tyrosine kinase inhibitor that selectively inhibits the vascular endothelial growth factor receptor-2 (VEGFR2), now being developed by Jiangsu Hengrui Medicine (China). Even at a low concentration apatinib can still perform magnificent VEGFR2 inhibitory activities, meanwhile at little higher concentration it can inhibit PDGFR and kinases as well, such as c-Kit and c-Src .The action sites of apatinib are the intracellular ATP binding site of the protein tyrosine receptor. Pharmacodynamical study shows that apatinib is able to inhibit the tyrosine kinase activity of VEGFR, block signal conduction after the combination of VEGF, finally contribute to stopping new blood vessel formation in tumor tissue.
