Dendreon Corporation is a biotechnology company whose mission is to target cancer and transform lives through the discovery, development and commercialization of novel therapeutics that harness the immune system to fight cancer. The Company uses its experience in antigen identification, antigen engineering and antigen-presenting cell processing to produce active immunotherapy product candidates to potentially stimulate a cell-mediated immune response. PROVENGE (sipuleucel-T) is Dendreon’s lead active cellular immunotherapy in Phase 3 development for prostate cancer. The Company also discovered Trp-p8, a cold receptor and transmembrane ion channel in pre-clinical development, which is over-expressed in breast, prostate, lung and colon cancers.
