WINNIPEG, MANITOBA–(Marketwire – July 28, 2010) – DiaMedica Inc., (TSX VENTURE:DMA) today announces the initiation of the Company’s autoimmune program with the success of DM-99 for the treatment of rheumatoid arthritis and other autoimmune diseases.
DM-99 was found to reduce joint swelling by up to 90% (p<0.001) in a collagen induced animal model of rheumatoid arthritis (RA) during the peak of the disease. A single dose of the protein DM-99 administered at the first signs of RA symptoms delayed the onset and severity of the disease. Furthermore, treatment given every forth day appears to have halted the autoimmune attack altogether.
“We believe that DM-99 is able to activate or increase the number of regulatory T cells (Tregs), which plays a vital role in suppressing the autoimmune attack in a wide range of autoimmune diseases,” commented Dr. Mark Williams, DiaMedica’s Vice President Research.
In a delayed hypersensitivity model, skin inflammation was reduced by 67% (p<0.05) and could be prevented for up to 14 days following a single administration of DM-99. DM-99 also delayed skin graft rejection by several days (p<0.05).
“Based on the ability of DM-99 to modulate the autoimmune attack in several autoimmune diseases, we will be starting a study shortly to determine if our more active form of DM-99, DM-199, can halt or slow the autoimmune attack in type I diabetes. DM-199, may be the only compound that both proliferates beta cells and protects them against the autoimmune attack in type I diabetes,” stated Rick Pauls, President and CEO of DiaMedica.
About DiaMedica
DiaMedica is a biopharmaceutical company focused on developing novel treatments for diabetes and neurological disorders. The Company’s type 2 diabetes program is based on a critical liver nerve signaling mechanism involved in enhancing insulin sensitivity after meal consumption. Two of DiaMedica’s products, DM-71 and DM-99, have previously demonstrated human efficacy in lowering blood sugar levels in people diagnosed with type 2 diabetes based on this novel nerve signaling mechanism.
DiaMedica has expanded its DM-199 recombinant protein program into neurological and autoimmune disorders. The Company has demonstrated that DM-99, the naturally occurring form of DM-199, confers neural protection (protects brain cells) and triggers neural stem cell proliferation (creates brain cells) for the treatment of numerous neurological disorders including Alzheimer’s disease. DiaMedica is listed on the TSX Venture Exchange under the trading symbol “DMA”.
