FR901228 in Treating Patients With Unresectable Stage III or Stage IV Malignant Melanoma

OBJECTIVES: Primary * Determine the response rate in patients with unresectable stage III or stage IV malignant melanoma treated with FR901228 (depsipeptide). Secondary * Determine the progression-free and overall survival of patients treated with this drug. * Determine the toxicity profile of this drug in these patients. OUTLINE: This is a multicenter study. Patients receive FR901228 (depsipeptide) intravenously (IV) over 4 hours on days 1, 8, and 15. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed every 3 months for 2 years and then every 6 months for 1 year. PROJECTED ACCRUAL: A total of 22-40 patients will be accrued for this study within 18 months.
