Biological Therapy in Treating Patients With Metastatic Melanoma
RATIONALE: Biological therapies such as cellular adoptive immunotherapy use different ways to stimulate the immune system and stop cancer cells from growing. Treating a person's white blood cells in the laboratory and then 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.
Biological: therapeutic tumor infiltrating lymphocytes
|Study Design:||Masking: Open Label
Primary Purpose: Treatment
|Official Title:||Phase I Study to Evaluate the Safety of Cellular Adoptive Immunotherapy Using Autologous CD8+ Antigen Specific T Cell Clones Targeting Cancer Testis Antigens for Patients With Metastatic Melanoma|
|Study Start Date:||October 2002|
|Study Completion Date:||June 2005|
- Determine the safety and toxicity of cellular adoptive immunotherapy comprising autologous CD8+ cytotoxic T-lymphocyte clones targeting cancer-testis antigens in patients with metastatic melanoma.
- Determine the duration of in vivo persistence of this therapy in these patients.
- Evaluate the antitumor effects of this therapy in these patients.
OUTLINE: Patients undergo leukapheresis to obtain peripheral blood mononuclear cells and then CD8+ cytotoxic T-lymphocyte (CTL) clones are generated ex vivo. Patients receive cellular adoptive immunotherapy comprising autologous CD8+ CTL clones targeting cancer testis antigens IV over 30 minutes on day 1. Patients also receive interleukin-2 subcutaneously every 12 hours on days 1-14 of courses 2-4. Treatment repeats every 3 weeks for 4 courses in the absence of disease progression or unacceptable toxicity. Patients who demonstrate a clinical response after completion of the fourth course are eligible to receive additional T-cell infusions.
Patients are followed for 9 months.
PROJECTED ACCRUAL: A total of 20 patients will be accrued for this study within 3 years.
