Abstract
PURPOSE: To establish a safe and tolerated regimen of an oral cytotoxic agent, temozolomide, and a cytostatic agent, thalidomide, in patients with unresectable stage III or IV malignant melanoma. PATIENTS AND METHODS: Patients with unresectable stage III or IV melanoma without brain metastases were entered successively onto four treatment cohorts: level 1, temozolomide 50 mg/m2/d for 6 weeks followed by a 4-week break; levels 2, 3, and 4, temozolomide 75 mg/m2/d for 6 weeks followed, respectively, by breaks of 4, 3, and 2 weeks. Thalidomide was started at 200 mg/d, and escalated to a maximum dose of 400 mg/d. Safety was assessed at weeks 2 and 4 and every 4 weeks thereafter; tumor response was evaluated every 8 to 10 weeks. RESULTS: Twelve patients were enrolled, three on each cohort. Therapy was generally well tolerated on all of the treatment schedules. Thalidomide at a dose of 400 mg/d was well tolerated in patients younger than 70, and 200 mg/d was well tolerated in older patients. The most common adverse events were grade 2 or 3 constipation and neuropathy, which were attributed to thalidomide. Five major responses (one complete, four partial) were documented, all at dose levels 2 to 4. Three of the five responding patients were in the over-70 age group. The median duration of response was 6 months (range, 4 to 17+ months), and the median overall survival was 12.3 months (range, 4 to 19+ months). CONCLUSION: The combination of temozolomide and thalidomide was well tolerated and had antitumor activity in patients with advanced melanoma, including elderly patients over 70 years old.
