A Phase II Clinical Trial of Chemotherapy With or Without Endostar® Continuous Intravenous Infusion in Refractory NPC

We define refractory nasopharyngeal carcinoma as the following: recurrence with radiation brain injury after radiotherapy, recurrence after the second or more courses of radiotherapy, standard treatment failure after recurrence, and first-line treatment failure after multiple distant metastasis. There is no standard treatment for refractory nasopharyngeal carcinoma. Platinum plus 5-Fu is the classic regimen for primary treatment of nasopharyngeal carcinoma. Endostatin is a multiple targeted angiogenesis inhibitor acting on tumor associated neovascular endothelial cells, normalizing the morphology and function of tumor vasculature, and indirectly leading to the quiescence or reduction of tumors. The purpose of this phase II clinical trial is to determine the efficacy and safety of nedaplatin plus continuous low dose 5-Fu intravenous infusion combined with endostar® (Recombinant Human Endostatin Injection) continuous intravenous infusion compared with nedaplatin plus continuous low dose 5-Fu intravenous infusion alone in refractory nasopharyngeal carcinoma. The study hypothesis is that nedaplatin plus continuous low dose 5-Fu intravenous infusion combined with endostar® continuous intravenous infusion is effective and safe in refractory nasopharyngeal carcinoma.
