This drug is under review by the U.S. Food and Drug Administration (FDA).
Below is a timeline of key regulatory milestones for this therapy.
- Drug:
- DM199
- Announced Date:
- June 23, 2026
- Indication:
- Chronic Kidney Disease Stage II or III
Announcement
DiaMedica Therapeutics Inc announced the dosing of the first two patients in an investigator-sponsored Phase 2 trial evaluating DM199 (rinvecalinase alfa) for the treatment of fetal growth restriction (FGR).
AI Summary
DiaMedica Therapeutics Inc. said the first two patients have been dosed in an investigator-sponsored Phase 2 trial of DM199, also called rinvecalinase alfa, for fetal growth restriction (FGR). FGR is a condition where a baby does not grow as expected during pregnancy, which can raise health risks for both the mother and baby.
The study will test whether DM199 can help improve blood flow and support better growth in babies affected by FGR. DM199 is a recombinant form of human tissue kallikrein-1, a protein being developed for several pregnancy- and circulation-related conditions. DiaMedica said the trial is an important step in learning more about the drug’s possible benefits in this serious condition.
The company is also studying DM199 in other clinical programs, but this update focused on the start of dosing in the Phase 2 FGR trial.

- Announced Date:
- June 16, 2026
- Indication:
- Chronic Kidney Disease Stage II or III
Announcement
DiaMedica Therapeutics Inc. announced that it has received a written response from the U.S. Food and Drug Administration (FDA) regarding the need for additional nonclinical reproductive toxicity data to support continued development of DM199 (rinvecalinase alfa) for the treatment of preeclampsia (PE).
AI Summary
DiaMedica Therapeutics said the FDA asked for more nonclinical reproductive toxicity data before it can keep developing DM199, also called rinvecalinase alfa, for preeclampsia. In response, the company is starting a rat pharmacokinetic study to measure how the drug is absorbed and distributed, along with a pharmacologic activity study to show how DM199 works in this species. DiaMedica is also reviewing recently completed rat data that it believes will help support the drug’s activity.
After the rat PK study is finished, DiaMedica plans to send the new information to the FDA for review. The company said it hopes these studies will support a future U.S. IND filing for preeclampsia. DiaMedica also expects to begin its preeclampsia study in Canada and the United Kingdom later this year.

- Indication:
- Chronic Kidney Disease Stage II or III
Announcement
DiaMedica Therapeutics Inc announced that enrollment in its pivotal Phase 2/3 ReMEDy2 trial of DM199 (rinvecalinase alfa) in patients with acute ischemic stroke (AIS) has reached 75% of the 200-patient threshold required to trigger the planned interim analysis.
AI Summary
DiaMedica Therapeutics said enrollment in its pivotal Phase 2/3 ReMEDy2 trial of DM199, also called rinvecalinase alfa, has reached 75% of the 200-patient level needed to start a planned interim analysis. The study is testing DM199 in people with acute ischemic stroke, a serious type of stroke caused by blocked blood flow to the brain.
The interim review will be done by an independent Data Safety Monitoring Board. Its job is to decide whether the trial should be adjusted, including whether the sample size should be re-estimated. DiaMedica said this step is meant to help make sure the study has enough power to show success while protecting the trial’s integrity. The company will not see the detailed interim results.
DM199 is designed to improve blood flow and help protect brain tissue by acting on a natural human enzyme involved in circulation and inflammation.

Announcement
DiaMedica Therapeutics In c nnounced that it has received a No Objection Letter (NOL) from Health Canada for its Clinical Trial Application to evaluate DM199 in a Phase 2 trial in patients with early-onset preeclampsia (PE).
AI Summary
DiaMedica Therapeutics Inc. announced it has received a No Objection Letter (NOL) from Health Canada for its Clinical Trial Application to study DM199 in a Phase 2 trial for patients with early-onset preeclampsia. The NOL clears the way for DiaMedica to initiate the Phase 2 study in Canada, advancing clinical evaluation of DM199—also known as rinvecalinase alfa—as a potential treatment for this serious pregnancy complication.
The company noted that its DM199 preeclampsia program recently received coverage on National Public Radio, raising public awareness. DiaMedica also included the usual cautionary language about forward-looking statements, reminding readers that trial timing and outcomes are subject to risks and uncertainties. The NOL represents a key regulatory step toward testing DM199’s safety and effectiveness in the targeted patient population.

- Indication:
- Chronic Kidney Disease Stage II or III
Announcement
DiaMedica Therapeutics Inc announced completion of a productive in-person pre-IND meeting with the United States Food and Drug Administration (FDA) for a planned study evaluating DM199 in preeclampsia.
AI Summary
DiaMedica announced it completed a productive in-person pre-IND meeting with the U.S. Food and Drug Administration about a planned study of DM199 for preeclampsia. Meeting minutes show the FDA requested one additional non-clinical study: a 10-day modified embryo-fetal development (EFD) and pre- and postnatal development (PPND) study in rabbits. DiaMedica has started preparations for that study and expects results by the second quarter of 2026. Company leadership said the meeting minutes give important regulatory clarity as they prepare an IND for a study in early-onset preeclampsia.
DiaMedica also said it will continue to engage with the FDA as it advances development of DM199. The company noted ongoing clinical work, including an investigator-sponsored Phase 2 trial that has dosed over 30 women with late-stage preeclampsia and shown encouraging safety and efficacy signals to date.

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.
