retroviral virus vector encoding cytosine deaminase
A replication competent retroviral vector, derived from the Moloney murine leukemia virus (MoMLV), encoding a modified form of the yeast suicide gene cytosine deaminase (CD) (Toca 511) used as an antineoplastic adjuvant. Upon transcranial injection, retroviral virus vector encoding CD preferentially enters and transfects tumor cells, and expresses cytosine deaminase, an enzyme that catalyzes the intracellular conversion of the prodrug flucytosine (5-FC) into the antineoplastic agent 5-fluorouracil (5-FU). After administration of 5-FC, the tumor can be eradicated upon activation of 5-FU. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
