Diamyd Medical has treated half of the patients in European registration study


Press Release, May 14, 2009                                                     

Diamyd Medical reported today that 166 out of a total of 320 patients, who are  
part of the European Phase III study of the Diamyd® diabetes vaccine, have now  
been included in the study. Discussions with  regulatory agencies are ongoing   
regarding how the brisk rate of recruitment in Europe can best be utilized in   
Diamyd's global Phase III program. The company estimates that the program will  
be fully recruited during 2009.                                                 

The global Phase III program includes two studies with respectively 320 patients
in Europe and 320 in the United States ages 10 to 20. The objective of the      
program is to evaluate the ability of the Diamyd® vaccine to halt or slow the   
autoimmune attack on insulin-producing beta cells, thereby preserving the body's
own ability to produce insulin in children and adolescents with recent onset    
type 1 diabetes.                                                                

“The rate of recruitment is now excellent. During a short period of time we have
nearly doubled the recruitment of patients for our European Phase III study,”   
says Elisabeth Lindner, President and CEO of Diamyd Medical. “This enables us to
increase the proportion of European patients in the global Phase III program,”  
Lindner continues.                                                              

Initially, the US study is only recruiting patients ages 16 to 20, an age group 
with a limited patient population. Diamyd Medical is pursuing discussions with  
the regulatory agencies about expanding the age range in the US to 10-20, and   
about altering the design of the Phase III program, so that countries with the  
fastest rate of patient recruitment can be utilized to the greatest extent.
