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.

liposome-encapsulated RB94 plasmid DNA gene therapy agent SGT-94
A systemic gene therapy anti-cancer agent composed of cationic liposomes, which encapsulates plasmid DNA encoding for the tumor suppressor gene RB94 and is complexed with anti-transferrin receptor single chain antibody fragment (TfRscFv), with potential antineoplastic activity. Upon systemic administration of liposome-encapsulated RB94 plasmid DNA gene therapy agent SGT-94, the TfRscFv portion of this agent selectively targets the tumor cells expressing transferrin receptors. TfRscFv binding to the transferrin receptor allows receptor-mediated endocytosis and transfection, followed by the expression of RB94 gene. This induces tumor cell apoptosis through an as-of-yet unknown pathway. RB94 is a modified, N-terminal truncated form of the full-length protein retinoblastoma gene RB110, and exerts enhanced antitumor activity. The transferrin receptor (TfR) functions in cellular iron uptake through its interaction with transferrin, and is overexpressed in a variety of tumor types. Check for active clinical trials using this agent. (NCI Thesaurus)
