RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die.

PURPOSE: Phase II trial to study the effectiveness of perifosine in treating patients who have metastatic or recurrent malignant melanoma.

OBJECTIVES:

• Determine the efficacy of perifosine, in terms of response rate, in previously untreated patients with metastatic or recurrent malignant melanoma.
• Assess the toxicity of this drug in these patients.

OUTLINE: This is a multicenter study.

Patients receive oral perifosine daily on days 1-21. Treatment repeats every 28 days for up to 6 courses in the absence of disease progression or unacceptable toxicity. Patients who achieve a complete response (CR) or partial response (PR) receive 2 additional courses after documentation of CR or stable PR (i.e., no further tumor shrinkage).

Patients are followed at 4 weeks and then every 3 months thereafter.

PROJECTED ACCRUAL: A total of 15-30 patients will be accrued for this study within 12-18 months.
