Vaccine Therapy in Treating Patients With Metastatic Melanoma
RATIONALE: Vaccines may make the body build an immune response to kill tumor cells.
PURPOSE: Phase II trial to study the effectiveness of vaccine therapy in treating patients who have metastatic melanoma that has not responded to previous therapy.
Biological: MART-1 antigen
Biological: gp100 antigen
Biological: incomplete Freund's adjuvant
|Study Design:||Masking: Open Label
Primary Purpose: Treatment
|Official Title:||Immunization of Patients With Metastatic Melanoma Using a Class II Restricted Peptide From the GP100 Antigen and Class I Restricted Peptides From the GP100 and MART-1 Antigens|
|Study Start Date:||October 1999|
- Determine the clinical response to immunization using gp100:44-59 antigen peptide plus gp100:209-217 (210M) and MART-1:26-35 (27L) antigen peptides in patients with metastatic melanoma who are HLA-DRB1*0401 and HLA-A0201 positive.
- Determine the clinical response to immunization using gp100:44-59 antigen peptide alone in patients with metastatic melanoma who are HLA-DRB1*0401 positive but HLA-A0201 negative.
- Determine the immunologic response in patients treated with these regimens as measured by changes in T-cell precursors from before to after treatment.
- Evaluate the toxicity profiles of these regimens in these patients.
OUTLINE: Patients are assigned to one of three immunization groups based on HLA-A0201 status and prior gp100:209-217 (210M) antigen peptide immunization:
- Group 1 (HLA-A0201 positive and no prior gp100:209-217 [210M] antigen peptide): Patients receive gp100:44-59 and gp100:209-217 (210M) antigen peptides emulsified together in Montanide ISA-51 (ISA-51) subcutaneously (SC) and gp100:44-59 and MART-1:26-35 (27L) antigen peptides emulsified together in ISA-51 SC.
- Group 2 (HLA-A0201 positive and prior gp100:209-217 [210M] antigen peptide): Patients receive treatment as in group 1.
- Group 3 (HLA-A0201 negative and no prior gp100:209-217 [210M] antigen peptide): Patients receive gp100:44-59 antigen peptide emulsified in ISA-51 SC alone.
- All groups: Treatment repeats every 3 weeks for 4 doses in the absence of disease progression or unacceptable toxicity. Patients with complete response after 4 doses receive a maximum of 2 additional doses. Patients with stable disease or minor, mixed, or partial response after 4 doses receive a maximum of 12 additional doses. Patients with no response after 4 doses receive immunization with the same peptides and interleukin-2 IV over 15 minutes every 8 hours for a maximum of 12 doses beginning 1 day after each immunization.
Patients are followed at 3-4 weeks.
PROJECTED ACCRUAL: A total of 45-75 patients (15-25 per immunization group) will be accrued for this study within 2 years.
