About DiaMedica

DiaMedica is a biopharmaceutical company focused on discovery and development of novel therapeutic compounds for diabetes and other major, medically-unmet diseases. DiaMedica's lead compound, DM-199, is a recombinant human protein that represents a novel approach to treating Type 1 and Type 2 diabetes. In a Type 1 diabetes model, DM-199 halted the autoimmune attack on beta cells by stimulating regulatory T-cells, and resulted in a 12-fold increase in C-peptide levels. In Type 2 diabetes models, DM-199 treatment stimulated proliferation of insulin producing beta cells, resulting in significant improvement in glucose control. DiaMedica is also developing a novel monoclonal antibody, DM-204 as a treatment for Type 2 diabetes. Chronic treatment with DM-204 in a Type 2 diabetes model resulted in significant improvement in blood glucose control and HbA1c levels and also significant decreases in blood pressure and serum cholesterol.

DiaMedica's DM-199 and DM-204 were both named Windhover's "2011 Top 10 Cardiovascular/ Metabolic Projects to Watch".

The Company is listed on the TSX Venture Exchange under the trading symbol 'DMA'.
