Phase II study of thalidomide in patients with metastatic melanoma.
The aim of this study was to determine the antitumour activity and toxicity of thalidomide in patients with metastatic melanoma. Between July 1999 and July 2001, 20 patients with metastatic melanoma were enrolled into this study. Patients were required to have progressive disease following standard therapies (unless there was a known contraindication for their usage) and to be free from symptomatic brain metastases. Thalidomide was administered orally at a starting dose of 200 mg/day, with increments of 100 mg every 7 days to a maximum dose of 800 mg/day. Patients experiencing intolerable side effects had their dose reduced to the maximum tolerated dose. Response and tolerance to treatment were assessed at 4 week intervals and therapy was continued until progression of disease or development of intolerable side effects despite appropriate dose reduction. All 20 patients were assessable for response. No objective response (complete or partial remission) was observed. In seven patients (35%), stable disease with a duration of 12-32 weeks (median 16 weeks) was seen. The median time to progression for all patients was 8 weeks (range 5-32 weeks) and the median overall survival was 20 weeks (range 7-130+ weeks). Treatment was generally well tolerated. Nine patients (45%) were able to tolerate the maximal planned dose of thalidomide (800 mg/day). Constipation, fatigue, somnolence and dryness of skin or mouth were the most common side effects. Thalidomide appears to possess cytostatic activity in patients with metastatic melanoma. Further studies of thalidomide in melanoma are warranted.
