Definition

A cancer vaccine consisting of allogeneic, immortalized dendritic cells (DCs) loaded with tumor specific antigens and activated, with potential immunostimulatory and antineoplastic activities. Upon intratumoral administration of the allogeneic dendritic cell vaccine COMBIG-DC, these activated DCs attract natural killer (NK) cells, induce an anti-inflammatory response leading to the induction of NK-cell-mediated tumor cell death. Upon release of tumor associated antigens (TAAs) from the lysed tumor cells, these antigens are taken up by antigen presenting cells which activate the immune system to elicit a potent cytotoxic T-cell (CTL) response against the TAAs, resulting in the death of TAAs-expressing tumor cells.
