DiaMedica Therapeutics Inc. is a clinical-stage biopharmaceutical company focused on developing therapies for severe ischemic diseases, with primary programs targeting preeclampsia and fetal growth restriction as well as acute ischemic stroke. The company's lead candidate is DM199 (rinvecalinase alfa), a recombinant form of human tissue kallikrein-1 (rhKLK1) protein designed to enhance endothelial health, microcirculatory blood flow, and tissue perfusion by increasing production of nitric oxide, prostacyclin, and endothelium-derived hyperpolarizing factor. DM199 has received Fast Track designation from the U. S. Food and Drug Administration for the treatment of acute ischemic stroke and is being investigated for additional indications including severe acute pancreatitis through a follow-on candidate, DM300.
DiaMedica Therapeutics Inc. does not currently generate revenue from product sales, as its operations are centered on research and development of clinical-stage drug candidates. The company's financial resources are directed toward advancing DM199 through preclinical and clinical trials for preeclampsia, fetal growth restriction, and acute ischemic stroke, as well as developing DM300 for potential use in severe acute pancreatitis. Funding is obtained through equity financing, collaborations, and other capital-raising activities to support ongoing development efforts.
The company operates through the following segments:
- Preeclampsia and Fetal Growth Restriction: This segment focuses on the development of DM199 for the treatment of preeclampsia and fetal growth restriction, conditions characterized by impaired placental perfusion and maternal endothelial dysfunction. DM199 is being evaluated in an investigator-sponsored Phase 2 study conducted at Tygerberg Hospital in Cape Town, South Africa, which includes dose-escalation, dose-expansion, and expectant management components for preeclampsia patients, along with a separate study for fetal growth restriction. Interim results from the study have shown statistically significant and sustained reductions in blood pressure up to 24 hours post-infusion, with no evidence of placental transfer and a favorable safety profile. Preparations are underway to initiate a global Phase 2 trial in early-onset preeclampsia in North America and the United Kingdom, following regulatory approval from Health Canada and planned submissions to the UK regulatory authorities.
- Acute Ischemic Stroke: This segment centers on the development of DM199 for the treatment of acute ischemic stroke, aiming to extend the therapeutic window beyond current thrombolytic therapies by promoting collateral blood flow and neuroprotection in the ischemic penumbra. The ReMEDy2 Phase 2/3 clinical trial (NCT05065216) is a global, adaptive design, randomized, double-blind, placebo-controlled study enrolling up to 728 patients across approximately 100 sites in the United States, Canada, Georgia, the United Kingdom, and six European countries. The trial evaluates physical recovery using the modified Rankin Scale at day 90, with secondary endpoints including stroke recurrence, NIHSS, and Barthel Index. DM199 has demonstrated a favorable safety profile in prior studies, with transient hypotension observed only at elevated doses and rapidly reversible upon infusion cessation.
DiaMedica Therapeutics Inc. operates in a competitive biopharmaceutical landscape where it faces competition from larger pharmaceutical and biotechnology companies developing therapies for preeclampsia and acute ischemic stroke. In preeclampsia, competitors include Comanche Biopharma with its siRNA candidate CBP-4888 targeting sFlt-1, as well as academic groups investigating repurposed agents like metformin. For acute ischemic stroke, the company competes with established thrombolytics such as alteplase and tenecteplase, mechanical thrombectomy devices, and emerging agents like edaravone/dexborneol, asundexian, and milvexian. DiaMedica's competitive advantages stem from its proprietary recombinant human kallikrein-1 platform, which offers potential benefits over plasma- or porcine-derived KLK1 products used in Asia, including consistent potency, reduced impurity risk, and scalable manufacturing. The company believes DM199 could qualify for 12 years of market exclusivity in the United States under the Biologics Price Competition and Innovation Act if approved.
DiaMedica Therapeutics Inc. serves patients and healthcare providers in the fields of maternal-fetal medicine and neurology, particularly those affected by preeclampsia, fetal growth restriction, and acute ischemic stroke. The company's clinical trials involve pregnant women with preeclampsia at institutions such as Tygerberg Hospital in South Africa, with plans to expand to sites in the United States, Canada, and the United Kingdom. For acute ischemic stroke, trial participants are enrolled at hospitals and stroke centers across North America, Europe, and other global regions, focusing on patients who are ineligible for or have not responded to thrombolytic therapy or mechanical thrombectomy. The company does not currently disclose specific commercial customer names, as it remains in the clinical development stage and has not yet commercialized any products.
