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.
A replication-defective, recombinant adenoviral vector encoding the wild-type human tumor-suppressor protein p53 gene with potential antineoplastic activity. Upon intratumoral administration, rAD-p53 binds to the coxsakie-and-adenovirus receptor (CAR) on tumor cells and enters cells selectively via receptor-mediated endocytosis, which may result in the overexpression of wild-type p53 intracellularly and p53-mediated tumor regression. In addition, this agent may stimulate the immune system to mount a cytotoxic T-lymphocyte (CTL) immune response against tumor cells, may activate natural killer (NK) cells to exert antitumor ‘bystander effects’ and may downregulate the expression of various oncogenes. The p53 protein blocks tumor cell cycle progression and directly initiates apoptosis; the p53 gene, a tumor suppressor gene, is deleted or mutated in a significant number of cancers. Check for active clinical trials using this agent. (NCI Thesaurus)
