Vaccine Therapy With or Without Interleukin-2 in Treating Patients With Metastatic Melanoma

RATIONALE: Vaccines may make the body build an immune response to kill tumor cells. Interleukin-2 may stimulate a person's white blood cells to kill tumor cells. Combining vaccine therapy with interleukin-2 may be an effective treatment for metastatic melanoma.

PURPOSE: Phase II trial to compare the effectiveness of vaccine therapy with or without interleukin-2 in treating patients who have metastatic melanoma that has not responded to previous therapy.

OBJECTIVES:

* Compare the efficacy of gp100:209-217(210M) peptide and MART-1:26-35(27L) peptide administered with or without high-dose interleukin-2 (IL-2) in patients with metastatic melanoma who are HLA-A0201 positive.
* Determine the efficacy of these peptides in patients who cannot receive IL-2.
* Compare the efficacy of IL-2 with or without these peptides in patients who need immediate treatment with IL-2.
* Determine the efficacy of MART-1:26-35(27L) peptide in patients who have received prior gp100 antigen.
* Compare the immunologic response experienced by patients who have received peptide, with or without IL-2, as measured by changes in T-cell precursors from before to after treatment.
* Compare the toxic effects of these regimens in these patients.

OUTLINE: This is a partially randomized study.

Patients are assigned to 1 of 4 treatment groups based on disease status and prior therapy.

* Group A (eligible to receive interleukin-2 (IL-2) but not in immediate need; no prior immunization with gp100 or MART-1 antigen): Patients are randomized to 1 of 2 treatment arms.

  * Arm I: Patients receive gp100 and MART-1 peptides emulsified in Montanide ISA-51 (ISA-51) subcutaneously (SC) on day 1. (Arm I closed as of 10/30/02).
  * Arm II: Patients receive both peptides as in arm I on day 1 and high-dose IL-2 IV over 15 minutes every 8 hours on days 2-5 (for up to 12 doses). (Arm II closed as of 10/30/02).
* Group B (ineligible to receive IL-2 due to other debilitating disease): Patients receive treatment as in group A, arm I.
* Group C (need immediate IL-2 therapy due to extensive and rapid progression of disease): Patients receive treatment as in group A, arm II. (Group C closed as of 10/30/02).
* Group D (prior immunization with gp100 antigen): Patients receive modified MART-1:26-35(27L) peptide emulsified in ISA-51 SC on day 1.

Treatment in all groups repeats every 3 weeks for 4 courses. Patients who achieve a minor, mixed, or partial response may receive up to 12 additional courses. Patients who achieve complete response receive 2 additional courses.

Patients are followed at 4-6 weeks.

PROJECTED ACCRUAL: A total of 103 patients (15-25 for group A, arm I; 19-33 for group A, arm II; and 15 each for groups B, C, and D) will be accrued for this study within 1 year.
