Descrição CEL-SCI hopes to make L.E.A.P.S. and bounds in preventing and treating deadly diseases. Its L.E.A.P.S. (Ligand Epitope Antigen Presentation System) technology modulates T-cells and may lead to synthetic vaccines for herpes, viral encephalitis, smallpox, and other diseases; the National Institutes of Health is testing CEL-1000 (a compound developed using L.E.A.P.S. technology) as a potential avian flu vaccine. The firm's lead drug candidate, however, is Multikine, which might make tumors more susceptible to radiation therapy and help a patient's body produce tumor-fighting antibodies. Multikine is undergoing clinical trials for the treatment of head and neck tumors.
