简要总结
This is a multicenter, open-label, prospective, phase 2 study of trastuzumab, bevacizumab, and paclitaxel as second-line treatment for patients with HER2-positive advanced gastric cancer who had progressed on first-line chemotherapy including trastuzumab or anti-HER2 agents.
详细描述
Trastuzumab has been administered at 6 mg/kg every 3 weeks after initial loading of 8 mg/kg during the first anticancer treatment, so in the second anticancer treatment, 4 mg/kg is administered every 2 weeks to maintain the same concentration. Bevacizumab is administered at 5 mg/kg at 2-weekly intervals used in metastatic colorectal cancer. Paclitaxel is administered on a standard schedule of 80 mg/m2 for 3 consecutive weeks followed by a 1-week break as an existing weekly regimen, and when side effects occur, the weekly dose is reduced by 25% to 60 mg/m2 for 3 weeks or administered every 2 weeks. Administer 80 mg/m2. Administration of this drug is set as one cycle of 4 weeks.

研究组 & 干预措施
TREAZURE
This is a single arm study. Trastuzumab has been administered at 6 mg/kg every 3 weeks after initial loading of 8 mg/kg during the first anticancer treatment, so in the second anticancer treatment, 4 mg/kg is administered every 2 weeks to maintain the same concentration. Bevacizumab is administered at 5 mg/kg at 2-weekly intervals used in metastatic colorectal cancer. Paclitaxel is administered on a standard schedule of 80 mg/m2 for 3 consecutive weeks followed by a 1-week break as an existing weekly regimen, and when side effects occur, the weekly dose is reduced by 25% to 60 mg/m2 for 3 weeks or administered every 2 weeks. Administer 80 mg/m2. Administration of this drug is set as one cycle of 4 weeks.
干预措施: trastuzumab, bevacizumab with paclitaxel (triple combination) (Drug)
