The NCI Drug Dictionary contains technical definitions and synonyms for drugs/agents used to treat patients with cancer or conditions related to cancer. Each drug entry includes links to check for clinical trials listed in NCI's List of Cancer Clinical Trials.

recombinant vaccinia-multiepitope melanoma peptides-B7.1-B7.2 vaccine
A cancer vaccine consisting of an inactivated recombinant vaccinia virus encoding epitope peptides derived from melanoma-related HLA-A2-restricted tumor-associated antigens (TAAs), including Melan-A(27-35), gp100(280-288) and tyrosinase(1-9), and two co-stimulatory B7 proteins, B7.1 (CD80) and B7.2 (CD86). Upon administration, recombinant vaccinia-multiepitope melanoma peptides-B7.1-B7.2 vaccine may stimulate a cytotoxic T-lymphocyte response against melanoma cells that express TAAs which share epitopes with the epitope peptides expressed by the vaccine viral vector, resulting in tumor cell lysis; vaccine viral vector-expressed co-stimulatory proteins B7.1 and B7.2 may enhance the cytotoxic T-lymphocyte immune response to the TAAs. Check for active clinical trials using this agent. (NCI Thesaurus)
