Diamyd Medical announced a collaboration with Cardiff University on a new study with the diabetes vaccine Diamyd®. The aim of the study is to optimize methods based on ultrasound guided lymph node biopsies for monitoring the cellular immune response to immunotherapy. The study is financed by Cardiff University while Diamyd Medical is supplying the study drug. Diamyd® will be administered intradermally in 12 patients with type 1 diabetes and the immune response will be monitored directly in the lymphatic fluid through ultrasound guided lymph node biopsies. Intradermal administration (via the skin) like direct intra-lymph-node administration of autoantigens, such as GAD, is believed to significantly enhance antigen specific tolerization, as compared to subcutaneous administration (under the skin). Chief Investigator is Professor Colin Dayan and Principal Investigator is Dr. Danijela Tatovic.
