- Drug:
- DM199
- Announced Date:
- July 17, 2025
- Indication:
- Chronic Kidney Disease Stage II or III
Announcement
DiaMedica Therapeutics Inc. announced positive interim results from Part 1a of the Phase 2 study of DM199 for the treatment of preeclampsia.
AI Summary
DiaMedica Therapeutics Inc. announced positive interim results from Part 1a of its Phase 2 study evaluating DM199 for the treatment of preeclampsia. In the dose-escalation phase, DM199 showed highly statistically significant and clinically meaningful reductions in both systolic and diastolic blood pressure. In addition, the treatment significantly reduced the uterine artery pulsatility index, indicating improved placental perfusion. Most importantly, DM199 did not cross the placental barrier and was well tolerated, addressing a major safety concern in preeclampsia treatment.
These encouraging outcomes support DM199’s potential as a first-in-class, disease-modifying therapy for a condition with no approved pharmacological treatments in the United States and Europe. The positive safety and efficacy benchmarks meet key study endpoints and bolster further investigation into the drug's role in improving maternal and fetal health in this underserved patient population.

Announcement
DiaMedica Therapeutics Inc announced the peer-reviewed publication entitled:Recombinant human tissue kallikrein-1 for treating acute ischemic stroke and preventing recurrence (Kasner, et al.) which is now available online and is scheduled for print publication in the February 2025 issue of Stroke.
AI Summary
DiaMedica Therapeutics Inc. announced that a new peer-reviewed article, "Recombinant human tissue kallikrein-1 for treating acute ischemic stroke and preventing recurrence" (Kasner et al.), is now available online and will appear in the February 2025 issue of Stroke. This publication explains how DM199, a recombinant form of human tissue kallikrein-1, works to treat acute ischemic stroke by increasing collateral circulation and protecting brain tissue.
The study shows that DM199 boosts the production of bradykinin, a substance that dilates blood vessels in the brain, enhancing blood flow and promoting the formation of new blood vessels, which may help repair injured tissue. These findings provide important scientific insight into DM199’s potential to improve outcomes in stroke patients by enhancing blood circulation in the affected brain regions, offering a novel approach to stroke treatment.
