"Celldex Therapeutics announced today that final data from its Phase 1 study of CDX-1401 in solid tumors, including long-term patient follow-up, have been published inScience Translational Medicine. The data demonstrate robust antibody and T cell responses and evidence of clinical benefit in patients with very advanced cancers and suggest that CDX-1401 may predispose patients to better outcomes on subsequent therapy with checkpoint inhibitors. CDX-1401 is an off-the-shelf vaccine consisting of a fully human monoclonal antibody with specificity for the dendritic cell receptor DEC-205 linked to the NY-ESO-1 tumor antigen. The vaccine is designed to activate the patient's immune system against cancers that express the tumor marker NY-ESO-1. While the function of NY-ESO-1 continues to be explored, references in the literature suggest that its expression might reflect the acquisition of properties that cancers find useful, such as immortality, self-renewal, migratory ability and the capacity to invade."
Editor's note: Cancer vaccines like CDX-1401 are a type of immunotherapy, meaning that they boost a patient's own immune system to fight cancer. CDX-1401 is able to attack tumor cells because the tumor cells have a molecule called NY-ESO-1 that CDX-1401 recognizes. We recently published a story about another treatment that is meant for patients whose tumors have NY-ESO-1.
