Vaccine Therapy in Treating Patients With Refractory Metastatic Melanoma

RATIONALE: Vaccines may make the body build an immune response to kill tumor cells.

PURPOSE: Randomized phase II trial to study the effectiveness of vaccine therapy in treating patients who have refractory metastatic melanoma.

OBJECTIVES:

• Determine whether an immunologic response can be obtained after administration of ESO-1 peptide vaccine comprising class I , II, or both peptides in HLA-A*201 or HLA-DPB1*04 positive patients with refractory metastatic melanoma expressing ESO-1.
• Determine the toxicity of this vaccine in these patients.
• Determine whether prior immunization with this vaccine results in increased clinical responsiveness in patients treated with interleukin-2.

OUTLINE: Patients are assigned to 1 of 3 groups according to HLA type.

• Group 1 (HLA-A*201 and HLA-DPB1*04 positive): Patients receive ESO-1 peptide vaccine comprising class I (ESO-1:157-165 [165V]) and class II (ESO-1:161-180) peptides subcutaneously once every 3 weeks for 4 courses in the absence of disease progression or unacceptable toxicity.
• Group 2 (HLA-A*201 positive and HLA-DPB1*04 negative):Patients receive ESO-1 peptide vaccine as in group I comprising class I peptide only.
• Group 3 (HLA-A*201 negative and HLA-DPB1*04 positive):Patients receive ESO-1 peptide vaccine as in group I comprising class II peptide only.

Patients who develop disease progression discontinue vaccinations and receive high-dose interleukin (IL-2) IV over 15 minutes every 8 hours for up to 4 days (maximum of 12 doses). Treatment with IL-2 repeats every 10-14 days for 4 courses in the absence of disease progression (after at least 2 courses) or unacceptable toxicity.

Patients who have stable disease or a mixed or partial response to vaccination or IL-2 therapy may be eligible for additional vaccine therapy. Patients who have a complete response to vaccine therapy are eligible for 1 additional treatment.

Patients are followed at 3 weeks.

PROJECTED ACCRUAL: A total of 45-90 patients (15-30 per treatment group) will be accrued for this study within 1 year.
