BACKGROUND: With the increasing survival of patients with metastatic colorectal cancer (CRC) there is a growing need for effective second- and third-line agents. We conducted a multicenter, phase II study to examine the combination of capecitabine and thalidomide (Cape/Thal) in patients with refractory metastatic CRC.
METHODS: Patients with previously treated stage IV CRC were eligible. Treatment consisted of capecitabine at 1,000 mg/m2 po BID for 14 days every 3 weeks and thalidomide, starting at 200 mg po QD continuously. Thalidomide was escalated individually to 600 mg po QD as tolerated. We analyzed overall survival (OS), progression-free survival, response, and toxicity rates.
RESULTS: Thirty-four eligible patients were enrolled. The median age was 57 years, and most patients had a normal performance status (65%). All patients had received prior chemotherapy and 19 (56%) had received 2 or 3 prior regimens. The median number of Cape/Thal cycles administered was 3 (range, 1-15). Grade 3/4 toxicities included fatigue (15%), venous thromboembolic events (12%), somnolence (12%), and constipation (9%). Grade 2 hand-foot syndrome occurred in 5 (15%) patients. There were no radiographic responses; 13 patients (38%) achieved stable disease. The median PFS was 2.6 months (95% confidence interval [CI] = 2.2-3.9) and the median OS was 7.1 month (95% CI = 5.2-12.0).
CONCLUSIONS: Though well-tolerated, the combination of capecitabine and thalidomide was not associated with objective tumor responses in a population of patients with previously treated metastatic CRC.
