vaccine therapy plus interleukin-2 in treating patients with stage iii or stage iv melanoma

Conditions: Melanoma (Skin)

Summary: rationale: vaccines made from melanoma cells may make the body build an immune response to and kill tumor cells. colony-stimulating factors such as gm-csf may increase the number of immune cells found in the bone marrow or peripheral blood. interleukin-2 may stimulate a person's white blood cells to kill melanoma cells. combining vaccine therapy with gm-csf and interleukin-2 may be kill more tumor cells. purpose: phase ii trial to study the effectiveness of vaccines made from melanoma cells with or without gm-csf followed by interleukin-2 in treating patients with stage iii or stage iv melanoma.

objectives: i. compare the effectiveness of vaccination with synthetic melanoma peptides pulsed on autologous dendritic cells versus vaccination with synthetic melanoma peptides plus sargramostim (gm-csf) in decreasing tumor burden in patients with high risk melanoma (pulsed autologous dendritic cell arm closed 1/8/2001). ii. determine whether these regimens result in increased tumor specific immune responses as measured in vitro and in vivo. iii. determine whether these regimens stimulate t-cell responses in these patients. outline: this is an open label study. patients are included in treatment arm ii only (arm i closed 1/8/2001): arm i: patients undergo leukapheresis to collect dendritic cells. patients receive a mixture of synthetic melanoma peptides (gp100 antigen, tyrosinase, and tetanus peptides) pulsed on autologous dendritic cells iv and subcutaneously (sc). arm ii: patients receive a mixture of synthetic melanoma peptides (gp100 antigen, tyrosinase, and tetanus peptides) and sargramostim (gm-csf) emulsified in montanide isa-51 sc and intradermally. patients receive vaccination during weeks 0, 1, 2, 4, 5, and 6 for a total of 6 doses and interleukin-2 sc daily on days 7-49. patients receive 3 additional vaccinations at different sites not involved with the tumor concurrently with the first 3 vaccinations. patients are evaluated at 8 weeks, 12 weeks, 6 months, 12 months, and 24 months. projected accrual: a total of 27-54 patients will be accrued for this study within 2 years.
