Vaccine Therapy With or Without Biological Therapy in Treating Patients With Metastatic Melanoma

RATIONALE: Vaccines may make the body build an immune response to kill tumor cells. Biological therapies such as sargramostim and interferon alfa use different ways to stimulate the immune system and stop cancer cells from growing. It is not yet known if vaccine therapy if more effective with or without biological therapy for melanoma.

PURPOSE: Randomized phase II trial to compare the effectiveness of vaccine therapy with or without biological therapy in treating patients who have metastatic melanoma.

OBJECTIVES:

* Determine immune response of vaccination with melanoma associated antigens (MART-1:27-35, gp100:209-217 (210M), and tyrosinase:368-376 (370D)) on the number of peptide specific CD8+ T-cell precursors in HLA-A2 positive patients with metastatic melanoma.
* Determine the influence of sargramostim (GM-CSF) and/or interferon alfa-2b (IFN-A) on the immune responses of these patients and toxicity of this melanoma peptide vaccine.
* Determine any antitumor and anti-pigmentary response that may result from immunization against MART-1, gp100 and tyrosinase peptides, and determine the relationship between such clinical observations and immune responses against lineage antigens with or without GM-CSF and/or IFN-A.
* Compare the relapse free survival and overall survival of patients treated with melanoma peptide vaccine alone or in combination with GM-CSF and/or IFN-A.

OUTLINE: This is a randomized, multicenter study.

Patients are randomized to 1 of 4 treatment arms.

* Arm I: Patients receive multiepitope peptide (MEP) vaccine comprising MART-1:27-35, gp100:209-217 (210M), and tyrosinase:368-376 (370D) peptides. Each peptide is separately emulsified in Montanide ISA-51 and administered subcutaneously (SC) (for a total of 2 injections per peptide) on days 1 and 15.
* Arm II: Patients receive MEP vaccine as in arm I and sargramostim (GM-CSF) subcutaneously (SC) daily on days 1-14.
* Arm III: Patients receive MEP vaccine as in arm I and interferon alfa-2b SC three times a week.
* Arm IV: Patients receive MEP vaccine as in arm I, GM-CSF as in arm II, and interferon alfa-2b as in arm III.

Treatment continues every 4 weeks for a maximum of 13 courses in the absence of disease progression or unacceptable toxicity.

Patients are followed every 3 months for 2 years, every 6 months for 3 years, and then annually thereafter.

PROJECTED ACCRUAL: A total of 92 patients (23 per arm) will be accrued for this study within 13-16 months.
