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.

GI-4000 vaccine
A vaccine containing a heat-killed recombinant Saccharomyces cerevisiae yeast transfected with mutated forms of Ras, an oncogene frequently found in solid tumors, with potential immunostimulant and antitumor activity. Upon administration, GI-4000 vaccine elicits an immune response by stimulating a specific cytotoxic T-cell response against the mutated forms of Ras. This may lead to a destruction of cancer cells expressing a Ras mutation. Check for active clinical trials using this agent. (NCI Thesaurus)
