Flavopiridol in Treating Patients With Metastatic Malignant Melanoma

A Phase II Study of Flavopiridol (HMR 1275; NSC 649890) in Patients With Previously Untreated Metastatic Malignant Melanoma

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 flavopiridol in treating patients who have metastatic malignant melanoma.

OBJECTIVES:

• Assess the efficacy of flavopiridol in patients with previously untreated metastatic malignant melanoma.
• Assess the toxicity of this treatment in these patients.
• Assess the time to progression, early progression rate, and response duration in these patients when treated with this regimen.

OUTLINE: This is a multicenter study.

Patients receive flavopiridol IV over 1 hour on days 1-3. Treatment continues every 21 days for a maximum of 6 courses in the absence of disease progression or unacceptable toxicity.

Patients are followed at 4 weeks, and then every 3 months until disease progression or death.

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