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. Diamyd® has demonstrated significant and
positive results in Phase II clinical trials in both type 1 and autoimmune type
2 diabetes patients (LADA) 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 world-wide license from
the University of California at Los Angeles regarding the therapeutic use of the
GAD65 gene. 

Diamyd Medical has sublicensed its UCLA GAD65 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 gene therapy using the
exclusively licensed and patent protected Nerve Targeted Drug Delivery System
(NTDDS). The company's lead gene therapy 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 in Pittsburgh (USA). The
Diamyd Medical share is quoted on the Stockholm Nordic Exchange in Sweden
(ticker symbol: DIAM B) and on the OTCQX-list in the US (ticker symbol: DMYDY)
administered by the Pink Sheets and the Bank of New York (PAL). Further
