Mechanism of action
From the NCI Drug Dictionary: A transforming growth factor beta2 (TGF-beta2) antisense gene-modified allogeneic tumor cell vaccine with potential immunostimulatory and antineoplastic activities. Belagenpumatucel-L is prepared by transfecting allogeneic non-small cell lung cancer (NSCLC) cells with a plasmid containing a TGF-beta2 antisense transgene, expanding the cells, and then irradiating and freezing them. Upon administration, this agent may elicit a cytotoxic T lymphocyte (CTL) response against host NSCLC cells, resulting in decreased tumor cell proliferation; vaccine immunogenicity may be potentiated by suppression of tumor TGF-beta2 production by antisense RNA expressed by the vaccine plasmid TGF-beta2 antisense transgene.
