Clinical Study on Treatment of Apatinib Mesylate in First-line Maintenance of Advanced Gastric Cancer

Clinical Study on Treatment of Apatinib Mesylate in First-line Maintenance of Advanced Gastric Cancer -- Multicenter, Open, One Arm Exploratory Study

At present, apatinib was approved for the treatment of advanced gastric cancer after second-line or gastroesophageal junction adenocarcinoma, is in the second one, experience of medication, clinical data, no chemotherapy so now intends to carry out 40 cases of small sample exploratory research, in the conventional chemotherapy after the onset, with APA for Nigeria maintenance treatment, with a preliminary understanding of apatinib in first-line advanced gastric cancer to maintain the efficacy and safety of the treatment, and explore the feasibility of anti generate small molecule targeted therapy in advanced gastric cancer vascular pattern.

Study Overview

• Status: Unknown
• Conditions: Advanced Gastric Cancer
• Intervention / Treatment: Drug: apatinib

Detailed Description

The incidence of gastric cancer in China is high, and there is no standard first-line chemotherapy regimen for advanced gastric cancer. Second-line therapy usually involves first-line treatment, without the use of drugs for combination or monotherapy, and no uniform treatment. Apatinib approved provides a good solution to this problem, but this study is in limit of validity standard after all into the row, not very good reaction in clinical practice for APA imatinib reality in the treatment of advanced gastric cancer. Therefore, it is necessary to make a prospective product study to understand the gap between clinical practice and research results. This study can evaluate apatinib in treatment of advanced gastric or gastroesophageal junction safe and effective parts of adenocarcinoma in clinical practice, and the specific usage (such as dose and period). The results of this study can help the future clinical practice specification of apatinib parts for the treatment of adenocarcinoma with advanced gastric or gastroesophageal reflux, the advanced gastric or gastroesophageal adenocarcinoma patients with parts get treatment more safe and effective in the treatment of.

At present, apatinib was approved for the treatment of advanced gastric cancer after second-line or gastroesophageal junction adenocarcinoma, is in the second one, experience of medication, clinical data, no chemotherapy so now intends to carry out 40 cases of small sample exploratory research, in the conventional chemotherapy after the onset, with APA for Nigeria maintenance treatment, with a preliminary understanding of apatinib in first-line advanced gastric cancer to maintain the efficacy and safety of the treatment, and explore the feasibility of anti generate small molecule targeted therapy in advanced gastric cancer vascular pattern.
