A genetically engineered, replication selective, infected cell protein (ICP) 34.5 gene-deleted, oncolytic human simplex virus type 1 (HSV-1) expressing the human immunostimulating cytokine interleukin-12 (IL-12), with potential antineoplastic activity. Upon intratumoral administration of HSV-1 expressing IL-12, the IL-12-expressing HSV-1 preferentially infects and replicates in tumor cells of neuronal origin causing viral-mediated tumor cell lysis. The released virus particles, in turn, infect and replicate in neighboring tumor cells. In addition, the IL-12-expressing HSV-1 promotes the secretion of IL-12 by the tumor cells. IL-12 promotes the activation of natural killer cells, which induces both the secretion of interferon-gamma and a cytotoxic T-lymphocyte (CTL) response against the tumor cells. This results in both immune-mediated tumor cell death and further inhibition of tumor cell proliferation. Deletion of the gene encoding for ICP34.5 imparts tumor selectivity by preventing replication in healthy cells. Check for active clinical trials using this agent. (NCI Thesaurus)
