A cell-based vaccine composed of allogeneic dendritic cells pulsed ex-vivo with an autologous myeloma idiotype with potential antineoplastic activity. Upon administration, allogeneic dendritic cell-myeloma idiotype vaccine may stimulate the host immune system to mount a specific cytotoxic T-lymphocyte (CTL) response against myeloma cells, resulting in cell lysis. Check for active clinical trials using this agent. (NCI Thesaurus)
