Diamyd® study published in Europe's leading scientific diabetes journal


Press Release, May 4, 2009 

Diamyd Medical reports that the respected scientific journal Diabetologia has   
published an article containing the results of a study demonstrating that the   
Diamyd® vaccine significantly reduces the risk that patients with LADA (Latent  
Autoimmune Diabetes in Adults) will require treatment with insulin still after  
five years. The results that now have been published, were previously presented 
at the EASD meeting in Rome, August 2008.                                       

Approximately ten percent of all diabetes patients have LADA, and patients with 
the disease normally require treatment with insulin within a few years from     
diagnosis.                                                                      

”Increasing attention is being paid to LADA patients as a group. There is       
currently no treatment that can slow the course of the disease, and our positive
results are receiving a lot of attention from both doctors and patients," says  
Elisabeth Lindner, President and CEO of Diamyd Medical.                         

The title of the article is “GAD65 vaccination: 5 years of follow-up in a       
randomised dose-escalating study in adult-onset autoimmune diabetes.” The       
authors are C.-D. Agardh, K. F. Lynch, M. Palmér, K. Link and Å. Lernmark.      

The study included 47 LADA patients who were, with a four week interval, treated
with two injections of the Diamyd® diabetes vaccine in varying doses or with    
placebo. The patients were then followed for five years. The patients treated   
with 20 micrograms of Diamyd® showed the best results. The results after five   
years demonstrate that the Diamyd® vaccine significantly reduced the risk that  
the patient would need insulin treatment compared with placebo. The vaccine has 
also proven to be safe, and has not been linked with any serious side effects.  

The article is published on the journal's website                               
(www.diabetologia-journal.org), and will also be published in the print edition 
in the near future. The article is available for free for one month via the
