Current chemotherapeutic regimens for nonsmall cell lung cancer (NSCLC) have reached a plateau over the last few years. Targeted therapy makes use of tyrosine kinase inhibitors (TKIs) to suppress a number of signaling pathways including epidermal growth factor receptor and vascular endothelial growth factor which are active in NSCLC biology. In this study, we used sunitinib, a multi-target receptor TKI, combined with chemotherapy for unresectable/metastatic NSCLC. This open label Simon's 2 stage clinical trial enrolled a total of 6 NSCLC patients who received docetaxel (40 mg) and cisplatin (50 mg) on day 1 of each cycle (14 day interval between cycles) and sunitinib (25mg qd for 10 days between cycles) for a total of 12 cycles (24 weeks), after which patients received maintenance therapy with vinorelbine (30mg TIW) until disease progression. The sample size was based on a Simon's Optimal Two-Stage Designs for Phase II clinical trials. The expected response rate was set as 35% for P0 and as 60% for P1. The study was designed for a minimum of 6 patients for first stage and 15 patients until second stage with a significance level alpha = 0.10 and power = 70%. Diagnosis of a poor response in the second of 6 patients in Stage I or seventh of the 15 patients in Stage II would lead to early termination of the trial. The overall response rate was 66.7%. Four patients had an overall survival >60 months. The time to PFS ranged from 3 to 42 months. The combination therapy was well-tolerated. Sunitinib combined with chemotherapy shows promise and warrants further investigation.
