Autologous Dendritic Cell Therapy for Type 1 Diabetes Suppression: A Safety Study

The dendritic cells will be treated ex vivo with the antisense oligonucleotides and cryopreserved in aliquots for subsequent intradermal administration into sites closest to the physical location of the pancreas inside the body. Physiologic, biologic and immunologic responses to the dendritic cell vaccine will be evaluated over the period of the trial. The first group of volunteers will receive autologous dendritic cells without any ex vivo treatment (7/15) and the second group will be administered iDC (8/15). If there is no evidence of toxicity or adverse events associated with the dendritic cell vaccine, and only upon FDA and IRB approval we will initiate a new study comparing efficacy of control DC and iDC in improving glycemia and reversing autoimmunity in new-onset patients.
