Biological Therapy in Treating Patients With Metastatic Melanoma
RATIONALE: Biological therapies use different ways to stimulate the immune system and stop tumor cells from growing. Treating a person's white blood cells in the laboratory and reinfusing them may cause a stronger immune response and kill more tumor cells.
PURPOSE: Phase I trial to study the effectiveness of biological therapy in treating patients who have metastatic melanoma.
|Study Design:||Primary Purpose: Treatment|
|Official Title:||Phase I Study to Evaluate the Safety of Cellular Adoptive Immunotherapy Using Autologous CD4+ Antigen-Specific T Cell Clones for Patients With Metastatic Melanoma|
|Study Start Date:||November 2001|
|Study Completion Date:||August 2008|
- Determine the maximum tolerated dose of autologous CD4+ antigen-specific T-cells for cellular adoptive immunotherapy in patients with metastatic melanoma.
- Determine the safety and toxicity of this regimen in these patients.
- Determine the duration of in vivo persistence of adoptively transferred CD4+ antigen-specific T-cell clones in these patients.
- Determine the antitumor effects of this regimen in these patients.
OUTLINE: This is a dose-escalation study.
Patients undergo leukapheresis to collect peripheral blood mononuclear cells. CD4+ antigen-specific T-cell clones are generated over the next 2-3 months using immunogenic peptides MART1, tyrosinase, or gp100.
Patients receive autologous CD4+ antigen-specific T-cells IV over 30 minutes.
Cohorts of 3-6 patients receive escalating doses of autologous CD4+ antigen-specific T-cells until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity.
Patients are followed on days 1 and 3 post T-cell infusion, and then once weekly for 12 weeks.
PROJECTED ACCRUAL: A total of 3-18 patients will be accrued for this study.
