DiaMedica Therapeutics Releases Preeclampsia White Paper and Announces Key Opinion Leader Webinar on DM199 (Rinvecalinase Alfa) for the Treatment of Preeclampsia

• Company to Host Preeclampsia Key Opinion Leader Event July 29, 2024 at 10 AM Eastern / 9 AM Central
• White Paper: The Potential of DM199 to Treat Preeclampsia

DiaMedica Therapeutics Inc. (Nasdaq: DMAC), a clinical-stage biopharmaceutical company focused on developing novel treatments for severe ischemic disease, today announced that it will host a virtual key opinion leader (KOL) event on Monday, July 29, 2024, at 10:00 AM ET to provide further insight into the expansion of its clinical development program for DM199 (rinvecalinase alfa) into preeclampsia, a significant, unmet medical need with no FDA-approved therapeutics.

The webinar will feature Prof. Stephen Tong, MD, PhD (The University of Melbourne), Prof. Catherine Cluver, MD, PhD (Stellenbosch University), and Prof. Susan Walker, MD, PhD (The University of Melbourne) who will discuss the unmet need and current treatment landscape for preeclampsia (PE), a life-threatening pregnancy associated vascular disorder with no approved therapeutics. This will be followed by a discussion on the uniquely on-target mechanism of action of DM199 (rinvecalinase alfa) as a potential treatment for PE, and the upcoming Phase 2, proof-of-concept, clinical trial of DM199 in PE anticipated to commence enrollment in the fourth quarter of 2024.

The event will focus on the rationale for DiaMedica's expansion of its DM199 (recombinant human tissue kallikrein-1 (rhKLK1)) clinical development program and provide an overview of the Phase 2 investigator-sponsored trial in preeclampsia and fetal growth restriction. DM199, through enhancing the body’s natural ability to produce nitric oxide, prostacyclin and endothelium-derived hyper polarizing factor, has the potential to lower blood pressure, enhance endothelial health and improve perfusion to maternal organs and the placenta.

A live question and answer session will follow the formal presentations.

About Preeclampsia

Preeclampsia is a serious pregnancy disorder that typically develops after the 20th week of gestation, characterized by high blood pressure and damage to organ systems, often the kidneys and liver. Affecting up to 8% of pregnancies worldwide, preeclampsia can pose significant risks to both the mother and baby, including risk of stroke, placental abruption, progression to eclampsia, premature delivery, and death. Symptoms may include severe headaches, vision changes, upper abdominal pain and swelling in the hands and face. Delivery of the baby, often very prematurely, is the only available option for stopping the progression of preeclampsia. Women who have had preeclampsia have three to four times the risk of high blood pressure and double the risk for heart disease and stroke.

About DM199 (rinvecalinase alfa)

DM199 is a recombinant (synthetic) form of human tissue kallikrein-1 (rhKLK1) in clinical development for acute ischemic stroke (AIS) and preeclampsia. KLK1 is a serine protease enzyme that plays an important role in the regulation of diverse physiological processes via a molecular mechanism that increases production of nitric oxide, prostacyclin and endothelium-derived hyperpolarizing factor. In the case of AIS, DM199 is intended to enhance blood flow and boost neuronal survival in the ischemic penumbra by dilating arterioles surrounding the site of the vascular occlusion and inhibition of apoptosis (neuronal cell death) while also facilitating neuronal remodeling through the promotion of angiogenesis. In PE, DM199 is intended to lower blood pressure, enhance endothelial health and improve perfusion to maternal organs and the placenta.
