Vaccine Therapy With or Without Interleukin-2 in Treating Patients With Metastatic Melanoma That Has Not Responded to Previous Treatment
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: Randomized phase II trial to compare the effectiveness of vaccine therapy plus interleukin-2 to that of vaccine therapy alone in treating patients who have metastatic melanoma that has not responded to previous treatment.
Biological: incomplete Freund's adjuvant
Biological: recombinant tyrosinase-related protein-2
|Study Design:||Allocation: Randomized
Masking: Open Label
Primary Purpose: Treatment
|Official Title:||Immunization of HLA-0201 Positive Patients With Metastatic Melanoma Using a Peptide From Tyrosinase-related Protein 2 (TRP-2)|
|Study Start Date:||June 2001|
|Study Completion Date:||August 2004|
- Determine the clinical responses in patients with HLA-A0201-positive refractory metastatic melanoma treated with tyrosinase-related protein-2:180-188 peptide vaccine alone.
- Determine the clinical response rate of patients who have an immediate need to receive interleukin-2 (IL-2) in addition to this vaccine.
- Compare the immunologic response, in terms of changes in T-cell precursors before and after treatment, in patients treated with this vaccine with or without IL-2.
- Compare the toxicity profile of these regimens in these patients.
OUTLINE: This is a randomized, open-label study.
Patients who need immediate interleukin-2 (IL-2) receive tyrosinase-related protein-2 (TRP-2):180-188 peptide vaccine emulsified with Montanide ISA-51 on day 1 and high-dose IL-2 IV over 15 minutes once every 8 hours on days 2-5. Treatment repeats every 3 weeks for up to 4 courses in the absence of disease progression or unacceptable toxicity.
Patients who do not need immediate IL-2 are randomized to 1 of 2 treatment arms.
- Arm I: Patients receive TRP-2:180-188 peptide vaccine emulsified with Montanide ISA-51 subcutaneously (SC) on day 1. Treatment repeats every 3 weeks for up to 4 courses in the absence of disease progression or unacceptable toxicity.
- Arm II: Patients receive TRP-2:180-188 peptide vaccine emulsified with Montanide ISA-51 SC once weekly on weeks 1-4. Treatment repeats every 7 weeks for up to 4 courses in the absence of disease progression or unacceptable toxicity.
Patients who have a complete response (CR) receive 1 additional course after achieving CR. Patients who have progressive disease while receiving vaccine alone may cross over to receive peptide vaccine with IL-2 for at least 2 courses.
Patients are followed at 3 weeks.
PROJECTED ACCRUAL: A maximum of 83 patients (19-33 who need immediate interleukin-2 (IL-2); 15-25 per treatment arm who do not need immediate IL-2) will be accrued for this study within 1 year.
