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.”

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). Further information is
