DIAMYD INFORMATION Press Release, Stockholm, Sweden, December 13, 2007 - Diamyd Medical AB (www.omxgroup.com, ticker: DIAM B; www.otcqx.com, ticker DMYDY) Diamyd Medical announced today that the leaving Director of Research and Development John Robertson has sold shares in the Company. ”Robertson has been on sick leave since the month of June and will be leaving the Company as the responsibility for manufacturing has been transferred to our US office in Pittsburgh. That he chooses to dispose of his shares must solely be due to personal reasons, as far as I can understand. Robertson has not been in contact with the Company during the sick leave and has thus not had any insight into Diamyd Medical since June,” says Anders Essen-Moller, chairman of the Company. “We are looking forward to the 30 month results from the type 1 diabetes study beginning of 2008 and to file our Phase III application in the US before the end of this year.” For further information, please contact: Stockholm office Anders Essen-Möller CEO and President +46 8 661 0026 investor.relations@diamyd.com Pittsburgh office Michael Christini President +1 412 770 1310 Michael.Christini@diamyd.com Diamyd Medical AB (publ).

About Diamyd Medical Diamyd Medical is a life science company developing treatments for diabetes and its complications. The company's furthest developed project is the GAD-based drug Diamyd® for autoimmune diabetes for which Phase III studies are planned. Diamyd® has demonstrated significant and positive results in Phase II clinical trials in Sweden. GAD65, a major autoantigen in autoimmune diabetes, is the active substance in Diamyd. GAD65 is also an enzyme that converts the excitatory neurotransmitter glutamate to the inhibitory transmitter GABA. In this context, GAD may have an important role not only in diabetes but also in several central nervous system-related diseases. Diamyd Medical has an exclusive worldwide license from the University of California at Los Angeles regarding the therapeutic use of the GAD65 gene. Diamyd Medical has sublicensed its UCLA GAD Composition of Matter license to Neurologix, Inc. in Fort Lee, New Jersey for treatment of Parkinson's disease with an AAV-vector. Other projects comprise drug development within therapeutic gene transfer using the exclusively licensed and patent protected Nerve Targeted Drug Delivery System (NTDDS). The company's lead NTDDS projects include using enkephalin and GAD for chronic pain, e.g., diabetes pain or cancer pain. All projects in this field are currently in preclinical phases. Diamyd Medical has offices in Stockholm, Sweden and Pittsburgh, PA. The Diamyd Medical share is quoted on the Stockholm Nordic Exchange in Sweden (NOMX ticker: DIAM B) and on the OTCQX-list in the United States (ticker: DMYDY) administered by the Pink Sheets and the Bank of New York (PAL).
