A cancer vaccine consisting of dendritic cells harvested from a patient with cancer and pulsed or transduced with a peptide fragment of carcinoembryonic antigen (CEA), a tumor-associated antigen expressed by a wide range of cancers. When the altered dendritic cells are returned to the patient, they may stimulate the host immune system to mount a cytotoxic T-lymphocyte immune response against tumor cells expressing CEA. Check foractive clinical trials using this agent.
