Salvage Therapy With Sunitinib,Docetaxel and Platinum on Metastatic or Unresectable Non Small Cell Lung Cancer

Sunitinib shows anti-tumor activity in a variety of human non-small cell lung tumor ex vivo models. Many Phases II and III clinical trials of sunitinib in several solid tumors are completed or still ongoing. So far, the efficacy of sunitinb has been confirmed by the phase III trial for imatinib-resistance or intolerance advanced gastrointestinal stromal tumor patients. And sutent was approved to effective by two phase II trials in advanced renal cell carcinoma patients after failure of immunotherapies, and one phase III trial in treatment-naive advanced renal carcinoma patients. Sunitinib (SUTENT ®) has been approved by U.S. Food and Drug Administration (FDA) for the treatment of advanced renal carcinoma patients and in gastrointestinal stromal tumor patients who are intolerant or progressed after imatinib mesylate. European Medicines Agency (EMEA) conditionally granted the marketing approval for the treatment of metastatic renal carcinoma patients after failure of immunotherapy. A phase II trial (A6181040 study) on non-small cell lung cancer patients treated with sunitinib alone showed anti-tumor activity. In 63 enrolled patients treated with 4/2 schedule (4 weeks treatment, then two weeks interruption), 7 patients are confirmed partial response (overall response rate, 11%), and median progress-free time is 14.3 weeks. Presently, a phase III study is underway on non-small cell lung cancer patients followed by and now is under recruiting. Non-small cell lung cancer cells often over-express vascular endothelial growth factor (VEGF) receptors. Besides, the expression of the VEGF ligands is also correlated with increased tumor angiogenesis, as well as shortened survival time. One study treated with VEGF-directed monoclonal antibody (bevacizumab) and VEGFR and platelet-derived growth factor receptor (PDGFR) small molecule inhibitors (sunitinib) showed that some non-small cell lung cancer patients are with anti-tumor activity. The chemotherapy drugs, such as docetaxel and platinum-based compounds, were with evidence that they have direct cytotoxicity to cancer cells. Therefore, the investigators are paying attention to the efficacy of combining sunitinib and conventional chemotherapy in this study. The study is designed as first line of salvage therapy on metastatic or unresectable non-small cell lung cancer patients. The main goals of this study is to evaluate the overall response rate (ORR) and duration of response (DR) of sunitinib in combinational with docetaxel and cisplatin in chemotherapy-naive advanced or metastatic non-small cell lung cancer patients.
