Cetuximab, Gastric Cancer, Nimotuzumab
Conditions
Brief summary
This study is intended to evaluate efficacy and safety of EGFR monoclonal antibody (Cetuximab/Nimotuzumab) in combination with a chemotherapy in gastric cancer patients with EGFR amplification.
Detailed description
This parallel, randomized, open-label, single-centre study will evaluate the effect on overall survival of EGFR monoclonal antibody (Cetuximab/Nimotuzumab) in combination with a chemotherapy compared to the chemotherapy alone in patients with EGFR-amplication advanced gastric cancer. Cetuximab will be administered as intravenous infusion of 500 mg/m2 (BSA) every 3 weeks, while nimotuzumab will be administered as intravenous infusion of 400mg every week. The chemotherapy consists of a combination of 12 cycles of mFOLFOX-6, 6-8 cycles of SOX, 6-8 cycles of CapOX. Treatment with cetuximab/nimotuzumab will continue until disease progression. The target sample size is 50-100 patients.
