title: Immunization with interleukin-2 transfected melanoma cells. A phase I-II study in patients with metastatic melanoma.
abstract: The safety, tolerance and clinical effects of immunization with irradiated, allogeneic melanoma cells that express high levels of HLA-A1 and -A2 and secrete IL-2 after transfection with the Interleukin-2 gene, will be assessed in HLA-A1 or HLA-A2 positive melanoma patients with metastatic disease. As a pilot, the first 5-10 patients, if no immediate regression of tumor lesions are observed, will in addition to immunization with these allogeneic tumor cells receive recombinant IL-2 in relatively low doses during three consecutive weeks on an outpatient basis. If no clinical remissions are induced in these first 5-10 patients, subsequent 5-10 patients will receive the same dose of melanoma cells without additional rIL-2. Thereafter the dose of injected melanoma cells will be increased in every following 5-10 patients, but all subsequent patients will receive only IL-2 producing, allogeneic tumor cells, without the addition of rIL-2.
