About
RATIONALE: Vaccines made from a person's dendritic cells mixed with tumor peptides and proteins may help the body build an effective immune response to kill tumor cells. Infusing the vaccine directly into the lymphatic system may cause a stronger immune response and kill more tumor cells.
PURPOSE: This randomized phase I trial is studying the side effects and best dose of two dendritic cell vaccines in treating patients with stage III or stage IV melanoma.
Full description
OBJECTIVES:
Primary
Secondary
OUTLINE: This is a randomized, open-label, dose-escalation study. Patients are randomized to 1 of 2 formulations of dendritic cell (DC) vaccines.
Patients achieving complete response receive 2 more courses of treatment (3 months apart). Patients achieving partial response receive up to 10 more courses of treatment (1 month apart) in the absence of disease progression or unacceptable toxicity.
In each arm, cohorts of 4-7 patients receive escalating doses of DC vaccine until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose at which no more than 1 of 7 patients experience dose-limiting toxicity.
Blood samples are obtained at baseline and periodically during and after treatment. Samples are examined by immunoenzyme techniques for immunologic measurements.
After completion of study therapy, patients are followed periodically for 10½ years and then annually thereafter.
PROJECTED ACCRUAL: A total of 40 patients will be accrued for this study.
