Peptide Vaccine With Resiquimod as an Immune Modulator for Patients With Resected Melanoma: A Pilot Study
PRIMARY OBJECTIVES:
I. Evaluate the immune response of each immunization regimen and determine an optimal
regimen in terms of immune response to recommend for phase II testing.
SECONDARY OBJECTIVES:
I. Evaluate the adverse events profile of each immunization regimen. II. Evaluate
disease-free survival.
TERTIARY OBJECTIVES:
I. Describe the immunological efficacy of the vaccine preparations with Gag267-274
(Gag:267-274 peptide vaccine) and resiquimod, as measured by the frequency and interferon
(IFN)gamma production of peptide-specific cytotoxic T lymphocytes (CTL).
II. Examine immune responses to the tumor antigen analog MART-1a (MART-1 antigen) versus the
xenoantigen Gag267-274.
OUTLINE: Patients are assigned to 1 of 3 treatment groups.
ARM I: Patients receive MART-1 antigen and Gag:267-274 peptide vaccine emulsified in
Montanide ISA 51 VG subcutaneously (SC) on day 1.
ARM II: Patients receive MART-1 antigen emulsified in Montanide ISA 51 VG SC followed by
resiquimod applied topically on day 1.
ARM III: Patients receive MART-1 antigen and Gag:267-274 peptide vaccine emulsified in
Montanide ISA 51 VG SC followed by resiquimod applied topically on day 1.
In all arms, treatment repeats every 21 days for up to 3 courses in the absence of disease
progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 3, 6, 9, 12 and 24 months.
Interventional
Allocation: Non-Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment
Immune response of each vaccination regimen, defined as a 2-fold or more increase from pre-treatment levels in the frequency of vaccine peptide-specific CTL as measured by tetramer staining
The proportion of successes will be estimated by the number of successes divided by the total number of evaluable patients. Exact binomial 95% confidence intervals for the true immune response rate will be calculated.
