Celldex’s proprietary technology platform uses fully human monoclonal antibodies administered directly to patients to target and stimulate dendritic cells and macrophages - key cells within the immune system. Our Antigen Presenting Cell Targeting Technology (APC Targeting Technology) utilizes the proprietary “huMAb” human monoclonal antibody technology to directly target the immune system. Our lead APC candidate is CDX-1307, a cancer immunotherapy for the treatment of colorectal, pancreatic, bladder, and breast cancers that is currently in two (2) phase I clinical trials. Celldex believes that product candidates using its APC Technology will be more effective at activating clinically relevant immune responses than standard immunotherapy strategies, and is building a significant portfolio of product candidates using this approach for a variety of disease indications.
