Phase II, Open-Label Trial in Patients With Stage IV Malignant Melanoma Using Melaxin as a Cancer Vaccine in Conjunction With BCG

Chemotherapy and immunotherapy are the main therapies for metastatic melanoma with the hope
of prolonging survival. The ideal immunotherapy would consist of the professional
antigen-presenting cell, the dendritic cell, with the entire repertoire of tumor antigens
inside. The best way to achieve this is by creating an autologous hybrid fusion cell of the
dendritic cell and tumor cell. In this study, melanoma tumor tissue surgically removed from
the patient will be disassociated into single cells, irradiated and fused to dendritic cells
produced by culturing the patient's blood monocytes. Prior to the electrofusion procedure,
the tumor cells are stained red and the dendritic cells are stained green. After fusion,
the uniquely colored fused cells, or dendritomas, are separated from the unfused cells by
use of a fluorescence activated cell sorter. This highly purified population is then
divided into 4 doses containing 250,000 dendritomas each and frozen. Each dose is thawed,
diluted to 1 ml with Sterile Saline for Injection containing 5% human serum albumin and
administered subcutaneously over a lymph node bed to the patient once every 4 weeks. A
separate injection of BCG is administered in the same area within 10 minutes of the
dendritoma injection. The safety and efficacy of the therapy will be evaluated in 25
