DiaMedica Enrolls First Patient in Phase II Human Clinical Trial for DM-83

WINNIPEG, MANITOBA--(Marketwire - March 18, 2008) - DiaMedica Inc. (TSX VENTURE:DMA), a drug discovery and development company focused on novel treatments for type 2 diabetes, has announced that it enrolled the first patient in the phase II proof of concept clinical trial of DM-83.

Dr. Karl-Gunnar Hidinger, DiaMedica's President, said the single-blind trial will demonstrate DM-83's level of effectiveness in controlling the blood glucose levels in twenty Type 2 diabetics after they have consumed a meal. Changes in insulin and glucose levels are the study's primary endpoints. Each patient will test both the effects of DM-83 as well as a placebo and therefore serve as their own control in this crossover study. Treatment will be concluded in the second quarter and results will be analyzed and released shortly thereafter. The results of this trial will be used to optimize the design of the next stage of clinical development for DM-83.

"This trial is another demonstration of the strength of our clinical development programs," said Dr. Hidinger. "We have discovered a very unique approach to treating this disease and believe we have found something quite important, as indicated by the clinical growth of our drug pipeline over the past six months."

The inability to use the insulin produced by the pancreas is a significant problem for people who suffer from Type 2 diabetes. This is demonstrated by the fact that many Type 2 diabetics have high levels of both glucose and insulin circulating in their bloodstream. DiaMedica believes that restoring insulin sensitivity and allowing the body to use its own naturally produced insulin is the key to combating this illness. Preclinical animal studies have demonstrated that DM-83 is able to restore insulin sensitivity to near prediabetic levels and has been shown to be very safe.

Diabetes is a widespread and rapidly growing disease, affecting over 180 million people world wide with over 90% of diabetics being diagnosed with the Type 2 form of the disease. According to the World Health Organization this number is expected to double during the next 15 years while the American Diabetes Association has estimated the annual economic cost in 2007 to the United States to be $174 billion. Global sales of oral diabetes drugs total $6 billion today and are expected to climb to $11 billion by 2011.

About DM-83

DM-83 has demonstrated the ability to restore insulin sensitivity in a type 2 diabetes animal model. The product is a novel combination of two known compounds with well established safety profiles that are used to treat other unrelated human conditions, one of which is used to improve cardiovascular conditions. Neither compound is able to restore insulin sensitivity on its own while combing the two results in a synergistic effect that restores insulin sensitivity to prediabetic levels.

About DiaMedica

DiaMedica is developing novel treatments for various stages of type 2 diabetes. The Company recently completed a successful phase IIa clinical trial with its lead product DM-71 which demonstrated the ability to reduce HbA1c levels in man. The Company has two other drugs in its clinical pipeline, DM-83 and DM-99. The Company believes that a dysfunctional parasympathetic nerve signal to the liver is a key factor in the development of type 2 diabetes.
