MINNEAPOLIS, MINNESOTA--(Marketwired - Nov. 4, 2015) - DiaMedica Inc. (TSX VENTURE:DMA) (OTCQB:DMCAF) a clinical-stage biotechnology company focused on developing novel protein therapeutics for vascular diseases, including stroke, and metabolic and kidney dysfunction, today provides a corporate development update.

  • The Company's near term focus is the advancement of DM199 into clinical studies for the treatment of acute ischemic stroke, to address a large unmet medical need;
  • Positioning DM199 to provide a treatment option for stroke patients beyond the currently limited 3-4.5 hour treatment window;
  • Exploring the potential for Asian partnership to advance DM199 as a biosimilar opportunity in Asian as a potential follow-on to a urine extracted marketed product;
  • DiaMedica will continue to develop DM199 for metabolic diseases including kidney dysfunction and acute kidney injury.

DM199 for Acute Ischemic Stroke

DM199 is positioned to significantly expand the therapeutic treatment window following an acute ischemic stroke from the current standard of care of 3-4.5 hours with tissue plasminogen activator ("tPA"), to up to 48 hours post stroke while also potentially complimenting tPA when administered together. Thereby providing an opportunity to greatly increase the number of patients eligible for treatment to potentially reduce the severity and to improve the functionl outcomes of patients inflicted with strokes.

DM199 is a recombinant form of the killikrein-1 ("KLK1") protein. A urine extracted form of KLK1, trade name Kailikang®, has been approved and is believed to be widely used for the treatment of acute ischemic stroke in China. DiaMedica believes that DM199 offers significant benefits over the urine-sourced product including the removal of any product supply constraints, very low manufacturing costs, reduced risk of endotoxins and a product capable of meeting the regulatory requirements for worldwide use. A subcutaneous formulation of DM199 may also make the treatment much easier to administer compared to intravenous administration.

DiaMedica plans to follow dual development paths for the treatment of acute ischemic stroke with DM199. The first path is a biosimilar strategy taking advantage of the approved Kailikang® product in China, and the second path being an accelerated development program for worldwide markets including the U.S. and Europe. This strategy is designed to produce a potential licensing or partnership deal with an Asian pharmaceutical company and a pivotal phase 2 proof of concept trial in the U.S. and Europe enabling partnering with a major pharmaceutical company.

DiaMedica has completed several safety and toxicology clinical trials with DM199. DM199 has established an excellent safety record with its single ascending and multiple ascending dose trials, and has also established maximum dose limiting tolerability of orthostatic hypotension at the very high dose levels, which is expected and consistent with the mechanism. There was no anti-drug antibody response after 28 days of therapy, and the formulation is free of endotoxin complications.

The Company is preparing the regulatory filing to initiate clinical trials of DM199 with both subcutaneous and intravenous routes of administration and will provide an update when the filing is completed.

"We are excited with the potential of DM199 with its promising mechanism of action and extensive clinical results with the naturally occurring version of KLK1 for the treatment of acute ischemic stoke," said Mr. Pauls, President & CEO of DiaMedica. "Following recent presentations at several forums, we are planning a business development and marketing initiative to Asia to initiate preliminary discussions with pharmaceutical companies in the Asian market."

DM199 for Metabolic and Kidney Diseases

DiaMedica will continue to develop DM199 for the metabolic disease area, with focus on a segment of the patients with kidney dysfunction and patients who suffer from acute kidney injury. DiaMedica is also evaluating DM199 and a follow-on product for a series of orphan drug indication where experts believe the products mechanism may have a major impact on the diseases.

About Acute Ischemic Stroke

Stroke is a major health issue in the U.S. and around the world today. There are 17 million strokes each year, and 1 in 6 males and 1 in 5 females will have a stroke in their lifetime. Most of these strokes, 87%, are what is termed ischemic strokes, a blockage rather than a hemorrhage (bleeding into the brain). The only FDA approved treatment option for acute ischemic stroke is tPA, the clot dissolving agent, trade name Activase®. tPA has proven to be effective when administered within 3-4.5 hours after a stroke, but it is estimated only 5-7% of acute ischemic stroke patients in the U.S. receive tPA because of the limited time window for starting treatment.

The projected total cost of care for stroke patients is forecasted to reach $240 billion in the U.S. by 2030 according to the World Stroke Organization.
