Abstract

Purpose: Based on the preclinical observation of upregulation of thymidine phosphorylase, the last enzymatic step in the conversion of capecitabine to 5-fluorouracil, by docetaxel along with good clinical tolerability of the combination of docetaxel and capecitabine using an optimized schedule in a previous phase I trial, we conducted this phase II study of this combination in patients with refractory or relapsed non-small cell lung cancer (NSCLC). Patients and Methods: Patients with NSCLC previously treated with at least one platinum- or paclitaxel-based regimen received docetaxel 36 mg/m2 on days 1, 8, and 15 and capecitabine 625 mg/m2 twice daily on days 5 to 18, every 4 weeks. The primary objective of the study was evaluation of progression-free survival (PFS) 26 weeks from initiation of treatment. Results: Thirty-six evaluable patients received 104 cycles of the combination. Severe toxicities were infrequent with only one patient requiring toxicity-related hospitalization. The 26-week PFS rate was 25% (95% confidence interval, 12-42) with an intent to treat median survival and 1-year survival rate of 9.1 months and 37%, respectively. Among 31 patients with measurable disease (Response Evaluation Criteria in Solid Tumors criteria), eight (26%; 95% confidence interval, 12-45) achieved partial responses. Conclusion: The combination of capecitabine and weekly docetaxel is well tolerated in previously treated patients with NSCLC. The relatively high 26-week PFS and 1-year survival, as well as the high response rate observed, encourages further evaluation of this regimen in NSCLC, either in randomized trials for refractory patients or as a potential treatment option for chemotherapy naive patients.
