One hundred sixty‐nine patients with histologic evidence of disseminated malignant melanoma, including patients with cerebral metastases, were entered into a Phase II study of the nitrosourea fotemustine. The treatment regimen consisted of a 100 mg/m² 1 hour IV infusion every week for 3 consecutive weeks, followed by a 4‐ to 5‐week rest period (induction therapy). In responding or stabilized patients, maintenance therapy consisted of 100 mg/m² every 3 weeks until the disease progressed. One hundred fifty‐three patients were evaluable for response. Three complete responses and 34 partial responses were observed (according to the World Health Organization criteria), leading to an objective response rate of 24.2% (95% confidence interval: 17.4% to 31.0%).
