PEG-Interferon Alfa-2b and Thalidomide in Treating Patients With Recurrent or Metastatic Melanoma

OBJECTIVES:

• Determine the response rate in patients with recurrent or metastatic malignant melanoma treated with PEG-interferon alfa-2b and thalidomide.
• Determine the quantitative and qualitative toxic effects of this regimen in these patients.
• Determine progression-free and overall survival of patients treated with this regimen.

OUTLINE: Patients receive PEG-interferon alfa-2b subcutaneously once weekly and oral thalidomide once daily. Treatment continues for at least 2 weeks but no more than 8 months in the absence of disease progression or unacceptable toxicity. Patients achieving a complete response (CR) receive PEG-interferon alfa-2b and thalidomide for 2 months beyond documentation of CR.

PROJECTED ACCRUAL: A total of 18-32 patients will be accrued for this study within 14-38 months.
