简要总结
The study is to evaluate the efficacy of Apatinib in patients with advanced or metastatic adenocarcinoma of stomach or gastroesophageal junction.
详细描述
The study is to investigate the efficacy of Apatinib as maintenance therapy after first fine treatment in patients with advanced or metastatic adenocarcinoma of stomach or gastroesophageal junction through progression-free survival(PFS). Apatinib will be given to patients who have received first-line chemotherapy with an efficacy assessment of stable disease(SD), complete response(CR), or partial response(PR) after 4 cycles. Patients were randomly assigned to 750mg group or 500mg group continually until disease progression or intolerable toxicity or patients withdrawal of consent, and the sample size is 40 individuals.

研究组 & 干预措施
Apatinib 750mg group
Apatinib mesylate tablets(ATAN) is taken 750mg every day orally, half hour after breakfast with warm water. The drug is taken 4 weeks one cycle until disease progression or intolerable toxicity or death.The dose of the study drug may be modified following the occurence of a clinically significant adverse event(AE).
干预措施: apatinib (Drug)
Apatinib 500mg group
Apatinib Mesylate Tablets(ATAN) is taken 500mg every day orally, half hour after breakfast with warm water. The drug is taken 4 weeks one cycle until disease progression or intolerable toxicity or death.Treatment will be discontinued if the subject is unable to tolerate a daily dose of 500mg.
