B16alphaGal melanoma vaccine 
A whole cell melanoma cancer vaccine with potential immunostimulating and antineoplastic activities. B16alphaGal melanoma vaccine contains three types of human melanoma cell lines that are genetically engineered to express the alpha(1,3)-galactosyl (alphaGal) epitope on cell surfaces. The agent stimulates a hyperacute rejection of whole melanoma cancer cells expressing alphaGal epitopes, initiated by opsonization by anti-alphaGal antibodies and followed by antibody-dependent cell-mediated cytotoxicity (ADCC) and cell lysis. This results in the stimulation of a broader cytotoxic T-lymphocyte response (CTL) directed against tumor antigens on melanoma cells that do not express alphaGal. AlphaGal is not normally expressed in humans because alpha(1,3)-galactosyltransferase (Alpha-GT), the enzyme that catalyzes the synthesis of alphaGal epitopes on glycoproteins and glycolipids, is not naturally present in humans and other primates. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
