OBJECTIVES:
Primary
* Determine the safety/toxicity of a single dose of B7-dendritic cell cross-linking antibody containing plasma in treating patients with stage IV melanoma.
Secondary
* Describe the immunological changes (Th1/Th2 balance, frequency of tumor specific cytotoxic T lymphocytes, and plasma cytokine profiles) in the treated patients.
* Determine the treatment impact on tumor growth (e.g., objective response, time to progression).
OUTLINE: Patients receive B7-dendritic cell cross-linking antibody IV once on day 1.
Patients undergo peripheral blood collection at baseline and periodically after infusion for analysis of dendritic cell activation, cytotoxic T-lymphocyte activity, immune cell impact, and serum cytokine changes using immunophenotyping and flow cytometry.
After completion of study treatment patients are followed every 2 months for 5 years.
