Phase II trial of fotemustine in patients with metastatic malignant melanoma.

Fotemustine is a novel chloroethylnitrosourea, that readily penetrates the blood brain barrier. Preliminary French studies reported encouraging results with fotemustine in patients with cerebral metastases of malignant melanoma. Thirty-one patients with histologically confirmed metastatic malignant melanoma were entered on a phase II trial. The treatment regimen consisted of fotemustine, administered intravenously as a rapid infusion, at a dose of 100 mg/m2 on day 1, 8 and 15 every 4 to 5 weeks. Objective response (CR + PR) was documented in 3 patients. Median time to treatment failure (TTF) was 44 days and median survival was 164 days. Life threatening toxicity did not occur; hematological toxicity and nausea and vomiting were the most common toxicities. Despite a somewhat disappointing response rate, objective responses were documented in patients with cerebral metastases. Since no other chemotherapeutic agent has shown therapeutic efficacy in cerebral metastases from malignant melanoma fotemustine therefore warrants further study.
