PART I

Item 1. Business

Overview

We are a clinical stage biopharmaceutical company committed to improving the lives of people suffering from severe ischemic disease with two main clinical programs focused on acute ischemic stroke (AIS) and preeclampsia (PE). Our lead candidate DM199 (rinvecalinase alfa) is the first pharmaceutically active recombinant (synthetic) form of the human tissue kallikrein-1 (rhKLK1) protein to be clinically studied in patients and has been granted Fast Track Designation from the U.S. Food and Drug Administration (FDA) for the treatment of AIS. Kallikrein-1 (KLK1), extracted from human urine, is an established therapeutic modality in Asia for the treatment of AIS, and KLK1 produced from pig pancreas, is an established therapeutic modality for the treatment of cardio renal disease, including hypertension, in Asia. We plan to advance DM199 through required clinical trials to create shareholder value by establishing its clinical and commercial potential as a therapy for AIS and PE. Longer term, we plan to develop DM300, our patented recombinant human ulinastatin, a broad-spectrum serine protease inhibitor, as a potential therapy for severe acute pancreatitis.

Our lead candidate DM199 is a recombinant form of human tissue kallikrein-1, which is a synthetic version of the naturally occurring protease enzyme kallikrein-1 and the first and only rhKLK1 undergoing global clinical development studies in both AIS and PE. Naturally occurring KLK1 (extracted from human urine or porcine pancreas) has been an approved therapeutic agent in Asia for decades in the treatment of AIS and hypertension associated with cardiorenal disease. DM199 is produced using recombinant DNA technology without the need for extracted human or animal tissue sources and thereby eliminates risk of pathogen transmission.

KLK1 is a serine protease enzyme that plays an important role in the regulation of diverse physiological processes via a molecular mechanism that may enhance microcirculatory blood flow and tissue perfusion by increasing production of nitric oxide (NO), prostacyclin (PGI2) and endothelium-derived hyperpolarizing factor (EDHF). 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 preeclampsia, DM199 is intended to lower blood pressure, enhance endothelial health and improve perfusion to maternal organs and the placenta, potentially disease modifying outcomes improving both maternal and perinatal outcomes.

We are developing DM199 to address two major critical unmet needs. In AIS, up to 80% of AIS patients are not eligible for treatment with currently approved clot-busting (thrombolytic) drugs or catheter-based clot removal (mechanical thrombectomy). DM199 is intended to enhance collateral blood flow and boost neuronal survival in the ischemic penumbra and inhibit neuronal cell death (apoptosis) while promoting neuronal remodeling and neoangiogenesis and offer a treatment option for patients who have otherwise no therapeutic options. In PE, there are currently no approved agents in any global market to safely lower maternal blood pressure and/or reduce the risk of fetal growth restriction. Historically, the major issue is that traditional vasodilators that are commonly used to reduce essential hypertension (eg, beta-blockers, angiotensin converting enzyme inhibitors (ACEi)) can readily cross the placenta and enter into the fetal circulation and cause harm to the developing fetus. We believe that DM199 is uniquely suited to treat PE since its inherent molecular size (~26 kilodaltons (KD)) is typically too large to cross the blood-placental barrier but may simultaneously reduce blood pressure and enhance microcirculatory perfusion to the maternal organs and placenta. DM199 has the potential to not only address hypertension of PE but also confer disease modifying outcomes for both maternal and perinatal outcomes including fetal growth restriction.

Our clinical program in AIS centers on our ReMEDy2 clinical trial of DM199 for the treatment of AIS. Our ReMEDy2 clinical trial is a Phase 2/3, adaptive design, randomized, double-blind, placebo-controlled trial intended to enroll approximately 300 participants at up to 100 sites globally. The adaptive design component includes an interim analysis by our independent data safety monitoring board after the first 200 participants have completed the trial. Based on the results of the interim analysis, the study may be stopped for futility, or the final sample size will be determined, ranging between 300 and 728 patients, according to a pre-determined statistical plan. Patients enrolled in the trial will be treated with either DM199 or placebo within 24 hours of the onset of AIS symptoms. The trial excludes patients who received mechanical thrombectomy (MT) or participants with large vessel occlusions in the intracranial carotid artery or the M1 segment for the middle cerebral, vertebral or basilary arteries or those that are otherwise eligible for MT. As a result of our recent protocol amendment, participants treated with tissue plasminogen activator (tPA) or tenecteplase (TNK), thrombolytic agents intended to dissolve blood clots, are now eligible for participation if they continue to experience a persistent neurological deficit and meet all other trial criteria, including repeat brain imaging to assess any hemorrhagic (bleeding) transformation. The study population is representative of the approximately 80% of AIS patients who do not have treatment options today, primarily due to the limitations on treatment with tPA/TNK and/or MT. The primary endpoint of the ReMEDy2 trial is physical recovery from stroke as measured by the well-established modified Rankin Scale (mRS) at day 90, specifically recovering to an mRS score of 0-1 (mRS range of 0-6). We believe that our ReMEDy2 trial has the potential to serve as a pivotal registration study of DM199 in this patient population.

Our clinical development program in PE is a safety, tolerability, and pharmacodynamic, proof-of-concept study in patients with PE and is financed as an investigator-sponsored trial (IST). This is a Phase 2 single center, open-label, multiple ascending dose (MAD, intravenous plus subcutaneous), dose escalation study being conducted at the Tygerberg Hospital, Cape Town, South Africa.

As announced in November 2024, enrollment commenced in the dose escalation portion of this study. Up to 90 women with PE, and potentially an additional 30 subjects with fetal growth restriction, may be evaluated. Part 1A of the PE study is recruiting up to 30 women planned for delivery within 72 hours and Part 2 will recruit up to 90 women in the expectant management setting. Part 1A of the study is intended to identify a suitable dose for Part 2 of the study and key outcomes from Part 1A are safety (including confirmation that DM199 does not cross the placental barrier), tolerability and identification of a suitable Phase 2 dose. Two efficacy endpoints being tracked are the change in maternal systolic blood pressure (SBP) after dosing and, for patients with early onset PE, improved baseline uterine artery blood flow. The results from Part 1A are expected in the second quarter of 2025.

We believe DM199 has the potential to treat a variety of diseases where restoring healthy function requires sufficient activity of KLK1 and the kallikrein-kinin system (KKS). Today, forms of KLK1 derived from human urine and the pancreas of pigs are approved and sold in Japan, China and South Korea to treat AIS, hypertension and other related vascular diseases. We believe millions of patients have been treated with these KLK1 therapies, including up to one million AIS patients now being treated annually with human urinary-derived KLK1 in China. Over 200 clinical studies in China have found urinary-derived KLK1 effective for increasing blood flow, decreasing ischemia in the penumbra, and reducing infarct size. Importantly, human urinary-derived KLK1 has not been shown to increase the risk of severe intracranial hemorrhage. Similarly, in the use of KLK1 to treat PE, preliminary evidence presented in several China-based studies using KLK1 derived from pig pancreas have shown reductions in maternal blood pressure and improvements in placental perfusion. However, given the small sample size of these studies, we remain cautious in our interpretation of the reported results and believe further study is necessary. We further note that there are numerous regulatory, commercial and clinical drawbacks associated with KLK1 derived from these sources which we believe can be overcome by developing a recombinant version of KLK1 such as DM199. We believe higher regulatory standards and the potential for impurities, endotoxins and chemical byproducts due to the inherent variability in the isolation and purification process are the primary reasons why KLK1 derived from these sources are not currently available and used in the United States or Europe. We are not aware of any recombinant version of KLK1 with regulatory approval for human use in any country, nor are we aware of any recombinant version in development, other than our drug candidate, DM199.

DM199 Background

Kallikrein-Kinin System

KLK1 is a serine protease, or protein, produced primarily in the kidneys, pancreas and salivary glands. KLK1 plays a critical role in the regulation of local blood flow and vasodilation (the widening of blood vessels, which decreases vascular resistance) in the body, as well as an important role in reducing inflammation and oxidative stress (an imbalance between potentially damaging reactive oxygen species, or free radicals, and antioxidants in the body).

KLK1 is involved in multiple biochemical processes. The most well-characterized activity of KLK1 is the enzymatic cleavage of low molecular weight kininogen (LMWK) to produce Lys-bradykinin (BK)-like peptides, collectively known as kinins, which activate BK receptors (primarily BK2R since the BK1R is typically only activated in pathological situations). As illustrated below, activation of BK receptors by kinins sets in motion metabolic pathways which locally produce nitric oxide, prostaglandins (primarily prostacyclin in endothelial cells) and endothelium-derived hyperpolarizing factor. Increased nitric oxide and prostacyclin work through the cyclic guanosine monophosphate (cGMP) and cyclic nucleotides cyclic adenosine monophosphate (cAMP) pathways, to preferentially relax smooth muscle cells and improve blood flow (through vasodilation), potentially protecting tissues and end-organs from ischemic damage. Scientific literature, including publications in Circulation Research, Immunopharmacology and Kidney International, suggests that lower endogenous KLK1 levels in patients are associated with diseases related to vascular disorders, such as stroke, renal diseases and hypertension. DM199, as a protein augmentation therapy, is intended to increase KLK1 levels to more fully activate the KKS driving the local production of NO, PGI2 and EDHF, to promote endothelial health and protect the brain and kidney from damage. By providing additional supply of the KLK1 protein, DM199 treatment could potentially improve blood flow and reduce inflammation in damaged end-organs, such as the brain and the kidneys, supporting their structural integrity and normal functioning.

We have conducted numerous internal and third-party analyses to demonstrate that DM199 is structurally and functionally equivalent to KLK1 derived from human urine. Specifically, the amino acid structure of DM199 is nearly identical to the human urine form, and the enzymatic and pharmacokinetic profiles are substantially similar to both human urine and porcine derived KLK1. The physiological effects of DM199 on blood pressure, from our completed studies, are similar to that of human urine and porcine-derived forms of KLK1. We believe that the results of this work suggest that the therapeutic action of DM199 will be the same or potentially better than that of the human urinary and porcine forms of KLK1 marketed in Asia.

We believe DM199 may provide a new treatment with significant benefits over the current standards of care by offering a therapeutic treatment option to a greater number of patients with the potential for fewer side effects.

Summary of Clinical Results

To date, clinical trials have been and/or are being conducted in the United States, Europe and Australia. We believe the clinical data generated to date by DM199 supports the continued development of DM199 as a treatment for AIS and PE.

In all completed studies, DM199 was shown to be generally safe and well tolerated. The primary adverse events noted in our studies with healthy volunteers included headache, erythema (redness), dizziness, injection site reaction and flushing. The most common adverse events in people with diabetes with or without chronic kidney disease included orthostatic hypotension, local injection site irritation/redness, and diarrhea. The most common adverse events in people with acute ischemic stroke include constipation, oral candidiasis (yeast/fungal infection of mouth) and nausea.

Supporting Data for Use of DM199 (KLK1)

KLK1 derived from human urine was approved in China in 2005. KLK1 derived from the pancreas of pigs has been approved in Japan for several decades. There is one company selling human urine derived KLK1 in China, and we believe human urine derived KLK1 is currently being used to treat up to one million AIS patients per year. We believe that approximately 20 companies are marketing porcine KLK1 in Japan, China and South Korea for hypertension, certain chronic kidney and other vascular diseases. We have identified several hundred papers supporting the clinical use of urinary and porcine derived KLK1 from China, Japan and South Korea.

Studies have shown that lower KLK1 levels are also a predictor of stroke recurrence. The red line in the graph below represents patients in the lowest KLK1 quartile who were at the highest risk for recurrence of stroke. (2,478 stroke patients and event free survival over 5 years).

Our Strategy

Our mission is to improve the lives of people suffering from severe ischemic diseases. Our near-term goal is to principally focus on executing our ReMEDy2 Phase 2/3 trial of DM199 in AIS and Phase 2 investigator-sponsored trial of DM199 in PE. Key elements of our strategy include:

AIS Background and Disease Pathology

Acute Ischemic Stroke Background

Stroke is characterized by the rapidly developing loss of brain function due to a blockage of blood flow in the brain. As a result, the affected tissues of the brain become inactive and may eventually die. Strokes can be classified into two major categories: AIS and hemorrhagic stroke. AIS is characterized by interruption of the blood supply by a blood clot (ischemia), while a hemorrhagic stroke results from rupture, or bleeding, of a blood vessel in the brain. Risk factors for stroke include, among other things, advanced age, hypertension (high blood pressure), previous stroke or transient ischemic attack (TIA), diabetes, high cholesterol, cigarette smoking, atrial fibrillation, physical inactivity and obesity.

More specifically, with respect to an ischemic stroke, at the site of a blood flow blockage in the brain, there exist two major ischemic zones – the core ischemic zone with nearly complete loss of blood flow (blood flow reduction of 75% to 90%, or more), and the surrounding ischemic penumbra, a rim of mild to moderately ischemic tissue surrounding the core ischemic zone. Within minutes, the significant lack of blood flow in the core ischemic zone deprives these cells of glucose and oxygen which rapidly depletes energy stores and triggers the loss of ion gradients, ultimately leading to neuronal cell death, or apoptosis. The ischemic penumbra zone, however, may remain viable for several hours via collateral arteries that branch from the main occluded artery in the core ischemic zone. Unfortunately, the penumbra is at great risk of delayed tissue damage due to inflammation which may also lead to neuronal cell death. As time goes on, a lack of blood flow in the core ischemic zone (infarct) may lead to fluid buildup (edema) and swelling which creates intracranial pressure. This pressure on the brain leads to tissue compression resulting in additional ischemia. Additional events in AIS include vascular damage to the blood vessel lining or endothelium, loss of structural integrity of brain tissue and blood vessels, and inflammation. A stroke can lead to permanent damage with memory loss, speech problems, reading and comprehension difficulties, physical disabilities and emotional/behavioral problems. The long-term costs of stroke are substantial, with many patients requiring extended hospitalization, extended physical therapy or rehabilitation, and/or long-term institutional or family care. However, provided the extended window of viability in the penumbra, next generation stroke therapies are being developed to protect valuable brain tissue during the hours to a week after a stroke.

Unmet Medical Need in AIS

According to the World Health Organization, each year 12.2 million people worldwide suffer a stroke, of which 7.6 million are acute ischemic strokes. According to the U.S. Centers for Disease Control and Prevention (CDC), approximately 800,000 people in the U.S. suffer a stroke each year, of which 87% are acute ischemic strokes. We believe that stroke represents an area of significant unmet medical need and a KLK1 therapy (such as DM199) could provide a significant patient benefit, in particular, given its proposed treatment window of up to 24 hours after the first sign of symptoms.

Limitations of Current Treatments for Acute Ischemic Stroke

Tissue plasminogen activator is a clot-dissolving medicine approved in 1996 by the U.S. FDA to treat acute ischemic stroke. Unfortunately, tPA has several drawbacks that limit its clinical usage. These include its narrow therapeutic window of 3 to 4.5 hours, potential complications with IV administration, and a high risk of bleeding into the brain (hemorrhages), which, due to a lack of reversibility, is the most severe complication of treatment, limiting its usefulness for the majority of stroke patients.

A newer treatment option for patients with acute ischemic stroke is mechanical thrombectomy (MT), a minimally invasive surgical procedure that uses a mechanical device to remove an intra-arterial blood clot in patients who present with large vessel occlusion (LVO) stroke. Large vessels are the main arteries supplying blood to the brain, including the internal carotid artery, middle cerebral artery, anterior cerebral artery, or basilar artery. During an MT procedure, a computed tomography (CT) angiogram scan confirms the location and size of the clot, which is then removed mechanically using a catheter threaded through the arteries. Clinical studies show the method can significantly increase a stroke patient's return to independent life and drastically reduce mortality. While MT represents a significant advancement in AIS care, LVO stroke as described above represents only approximately 30% of all AIS, thereby leaving the majority of patients without acute treatment. Moreover, the medical infrastructure required to identify and treat a patient with an LVO is such that this therapy is limited to nations with comprehensive healthcare systems.

The limitations of both tPA and endovascular thrombectomy treatments leave up to 80% of patients without acute intervention. Therefore, there is a significant unmet need for a widely accessible, off-the-shelf drug with a broad therapeutic window that is safe, effective, and reversible in the event of unwanted bleeding.

Acute Ischemic Stroke Treatment Options

According to the CDC, stroke incidence in the United States and its related effects include:

● Six in 10 people who die from stroke are women.

DM199 – Our Novel Solution for the Treatment of AIS

In response to an ischemic stroke, bradykinin 2 receptors (BK2) are significantly upregulated (increased) in the arteries affected by the stroke, the ischemic penumbra. This phenomenon has been observed in animal stroke models, showing a 36-fold increase on the ipsilateral side and a 10-fold increase on the contralateral side (PLOS ONE (2018), 13(6), e0198553.https://doi.org/10.1371/journal.pone.0198553). In these oxygen depleted arteries, the increased BK2 receptors signal the need for BK to bind and restore blood flow to these at-risk arteries in the ischemic penumbra. The treatment with DM199 is intended to increase the availability of BK to bind with the BK2 receptors to improve collateral circulation and increase oxygenation to the ischemic penumbra. In binding with the BK2 receptors expressed on endothelial cells (exposed to internal lumen of the artery), DM199, via production of bradykinin, activates the body’s natural physiologic processes and therefore does not need to pass through the blood brain barrier, which is a specialized structure that is difficult for many therapeutic agents to cross.

As depicted in the graphic below, we believe the mechanism of action for DM199 (KLK1) has the potential to preserve “at risk” penumbral brain tissue by facilitating the release of endothelial nitric oxide, prostacyclin and endothelium-derived hyper polarizing factor which may acutely increase cerebral blood flow by selectively vasodilating these penumbral arteries increasing collateral blood flow and restoring oxygen levels preserving/rescuing these cerebral tissues.

DM199 Acute Ischemic Stroke: Proposed Mechanism

In January 2019, we published a paper titled “Human Tissue Kallikrein in the Treatment of Acute Ischemic Stroke” in a peer reviewed journal (Therapeutic Advances in Neurological Disorders (2019), 12:1-15, .https://doi.org/10.1177/1756286418821918). The paper reviews the scientific literature covering the biochemical role of KLK1 and presents the mechanistic rationale for using KLK1 as an additional pharmacological treatment for AIS. In addition to the biochemical mechanism of KLK1, the review highlights supporting results from human genetics and preclinical animal models of brain ischemia. It also reviews published clinical results for treatment of AIS by a form of KLK1 that is isolated from human urine. This form has been approved for post-stroke treatment of AIS in China and data has been published from clinical trials involving over 4,000 patients. The paper offers a series of testable therapeutic hypotheses for demonstrating the long-term beneficial effect of KLK1 treatment in AIS patients and the reasons for this action.

We are developing DM199 to treat AIS patients with a therapeutic window of up to 24 hours after the first sign of symptoms, well beyond the current window of up to 4.5 hours for tPA, thereby filling a large unmet need for those patients who cannot receive tPA under the currently available treatment window of tPA. This important attribute could potentially make therapy available to the millions of patients worldwide who currently have limited treatment options.

Supporting Data from the Use of Urine-derived KLK1 for the Treatment of AIS in China

In China, Kailikang® is approved and marketed by Techpool Bio-Pharma Inc., a company controlled by Shanghai Pharmaceuticals Holding Co. Ltd. Kailikang has been approved for the treatment of AIS in China. We believe the initial treatment window is up to 48 hours after stroke symptom onset. Based on data from IQVIA real world and health data, other publications and our own internal analysis, we estimate that over 600,000 stroke patients in China were treated in 2022 with Kailikang. More than 50 published clinical studies, covering over 4,000 stroke patients, have demonstrated a beneficial effect of Kailikang treatment in AIS, including improvements in standard stroke scores, increased blood flow, and reduced infarct size/ischemia in the brain. In a double-blinded, placebo-controlled trial of 446 participants treated with either Kailikang or a placebo with initial treatment administered up to 48 hours after symptom onset showed significantly better scores on the European Stroke Scale and Activities of Daily Living at three weeks post-treatment and after three months using the Barthel Index, (China Journal of Neurology (2007),40:306–310).

Additionally, a comprehensive meta-analysis covering 24 clinical studies involving 2,433 patients concluded that human urinary KLK1 appears to ameliorate neurological deficits for patients with AIS and improves long-term outcomes, though a few treated patients suffered from transient hypotension (Journal of Evidence-Based Medicine (2012) 5:31-39, https://doi.org/10.1111/j.1756-5391.2012.01167.x)

Furthermore, in a retrospective study covering 300 consecutive AIS patients, subjects treated with human urinary KLK1 experienced a 6.5% absolute reduction (p=0.009) in recurrent strokes (39% relative) within one year (Brain and Behavior (2018), https://onlinelibrary.wiley.com/doi/pdf/10.1002/brb3.1033).

Preeclampsia Background and Disease Pathology

Preeclampsia Background

PE is a complex disorder affecting multiple body systems, occurring in 2 to 5% of pregnancies. It typically presents after 20 weeks of gestation with new onset hypertension and organ dysfunction, such as renal or liver impairment. It is a major cause of maternal and infant morbidity and mortality, especially in cases of early onset preeclampsia occurring before 34 weeks of gestation. Globally, this condition leads to the deaths of approximately 76,000 women and 500,000 newborns each year. Both pre-eclampsia and fetal growth restriction arise from poor placental function due to reduced placental perfusion, histopathologically evident as maternal vascular malperfusion injuries. Preeclampsia is further characterized by endothelial dysfunction and maternal vascular injury. This leads to hypertension and vasoconstriction of vessels, which damages many end organs supplied by these vessels. Preeclampsia is associated with placental and systemic inflammation, oxidative stress and an anti-angiogenic state. Hence, a drug that improves vasodilates blood vessels to improve organ and placenta perfusion and promotes vascular health (via pro-angiogenesis and reductions in inflammation and oxidative stress) may be a treatment for both conditions.

There are currently no FDA-approved therapeutics for PE and the only cure is delivery of the fetus, often prematurely. Control of blood pressure is the mainstay treatment for preeclampsia, but it does not modify progression of the disease and first-line hypertension medications ACE inhibitors and angiotensin receptor blockers (ARBs) are contraindicated due to causing fetal harm. Magnesium sulfate is used to prevent seizures in women and steroids are given to enhance fetal lung maturation.

Stage 1: Placental Disease

The maternal spiral arteries supply blood to the intervillous space of the placenta, undergoing significant structural, cellular, molecular, and functional changes from approximately week 10 to week 22 of gestation to support the growing fetus's increasing metabolic demands. During the first trimester, placental trophoblasts invade these arteries, replacing the endothelial cells and smooth muscle cells with extravillous trophoblast cells, resulting in the loss of vasomotor control and a transformation into rigid, fixed-diameter vessels. This process enlarges the vessel diameter by at least 10-fold, creating a low-resistance, high-capacity uteroplacental interface that allows for maximal and constant blood flow to the villous. The remodeled spiral artery network is essential for efficient nutrient and waste exchange, as the uteroplacental blood flow increases from 45 mL/min to 750 mL/min at term to support the high metabolic demands of the fetus. In PE, trophoblast invasion is impaired leading to incomplete remodeling of the spiral arteries and shallow placentation. This defective placentation in preeclampsia results in high resistance uterine circulation, causing impaired placental perfusion.

Stage 2: Maternal Vascular Disease and Subsequent Endothelial Dysfunction

When deprived of adequate blood flow, the hypoxic placenta experiences oxidative stress and releases antiangiogenic factors (sFlt-1, sEng), proinflammatory cytokines (TNF-α, IL-6), and other harmful substances into the maternal blood stream. These factors damage the maternal endothelium, elevate blood pressure, and contribute to organ damage. Moreover, this damage also depresses intrauterine blood flow causing reduced placental perfusion leading to a negative feedback loop. This cycle accelerates further with the increasing metabolic demands of a growing fetus, creating the perfect ischemic storm.

Unmet Medical Need in Preeclampsia

According to the Preeclampsia Foundation, one in every 12 pregnancies is affected by preeclampsia, with an annual incidence of approximately 200,000 pregnancies in the United States. Early-onset preeclampsia, which occurs before 34 weeks of gestation, affects up to 30,000 pregnancies annually and is more severe than late-onset preeclampsia (occurring after 34 weeks). Early-onset preeclampsia poses a higher risk of fetal morbidity and mortality, with infants being born significantly earlier, increasing their risk of future developmental challenges. Women with preeclampsia are twice as likely to develop heart disease or suffer a stroke and four times as likely to develop high blood pressure. Additionally, preeclampsia disproportionately affects African American women, who are 60% more likely to develop the condition than white women and are also more likely to experience severe forms of preeclampsia

DM199 – Our Novel Solution for the Treatment of Preeclampsia

DM199 is being developed as a potentially disease-modifying treatment to safely extend gestation and improve maternal and fetal outcomes in preeclampsia. In the maternal vasculature, DM199 may lower blood pressure, improve endothelial health, and enhance blood flow to key organs. It also has the potential to increase placental perfusion by dilating intrauterine arteries, which could promote fetal growth and reduce harmful placental factors such as sFlt-1 and sEng. This effect is believed to result from the inadequate remodeling of spiral arteries supplying the placenta, leaving endothelial and smooth muscle cells intact and vasoactive, making them a suitable pharmaceutical target for DM199.

A key potential safety advantage of DM199 in preeclampsia is that it is a large protein that is not expected to cross the placental barrier due to its molecular size and the absence of known active transport mechanisms for serine proteases. In contrast, small molecules, including most oral medications, passively cross the placental barrier, while monoclonal antibodies are transported through active transport mechanisms. This was further supported by a placental transfer study conducted in rodents, which demonstrated that DM199 remained confined to the maternal circulation. By avoiding transfer to the fetus, DM199 potentially offers a significant safety advantage over small molecules such as ACE inhibitors, angiotensin receptor blockers, and phosphodiesterase 5 (PDE5) inhibitors (e.g., sildenafil), which are known to cross the placental barrier and cause harm to the fetus.

The mode of action of DM199 is believed to involve the increased production of endothelial nitric oxide, prostacyclin, and endothelium-derived hyperpolarizing factor, pathways that are typically suppressed or impaired in preeclampsia. Additionally, DM199 may enhance vascular endothelial growth factor (VEGF) signaling, which is disrupted in preeclampsia due to elevated levels of circulating sFlt-1. This mechanism is thought to involve activation of the bradykinin 2 receptor, leading to either direct transactivation of the VEGF2 receptor or crosstalk between the nitric oxide and VEGF intracellular signaling pathways.

DM199 has demonstrated blood pressure reductions in multiple prior studies. New results from analysis of all participants with elevated blood pressure (baseline systolic blood pressure ≥ 130 mmHg) from the DM199 Phase 2 REDUX clinical trial, in three types of chronic kidney disease (CKD), demonstrated a statistically significant reduction in systolic blood pressure (SBP) at day 95:

REDUX Phase 2 CKD Trial Results: Baseline SBP*

Day 95 Change from Baseline -7.7 mmHg -12.6 mmHg -22.1 mmHg

Number of Participants 47 31 15

*Includes participants from all cohorts

DiaMedica has also completed studies on fertility, embryofetal development and pre- and post-natal development in animal models, which support the potential safety in pregnant humans. As described above, the placental transfer study in pregnant rodents demonstrated that DM199 did not cross the placental barrier. Specifically, DM199 was detectable in the maternal blood, but undetectable in the fetal blood.

Our Competition and Current Treatments for Acute Ischemic Stroke and Preeclampsia

The biopharmaceutical industry is highly competitive and characterized by rapidly advancing technologies that focus on rapid development of proprietary drugs. We believe that our DM199 product candidate, development capabilities, experience and scientific knowledge provide us with certain competitive advantages. However, we face significant potential competition from many different sources, including major pharmaceutical, specialty pharmaceutical and biotechnology companies, academic institutions, governmental agencies and other research institutions. Any product candidates that we successfully develop and commercialize will compete with existing therapies and new therapies that may become available in the future.

Many of our competitors, either alone or with their strategic partners, have substantially greater financial, technical and human resources than we do, and greater experience in obtaining FDA and other regulatory approvals of treatments and commercializing those treatments. Accordingly, our competitors may be more successful than us in obtaining approval for competitive products and achieving widespread market acceptance. Our competitors’ treatments may be more effectively marketed and sold than any products we may commercialize, thus limiting our market share and resulting in a longer period before we can recover the expenses of developing and commercializing our DM199 product candidate.

Mergers and acquisitions in the biotechnology and pharmaceutical industries may result in even more resources being concentrated among a smaller number of our competitors. Smaller or early stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. These activities may lead to consolidated efforts that allow for more rapid development of competitive product candidates.

We also compete for staff, development and clinical resources. These competitors may adversely impact our ability to: recruit or retain qualified clinical, scientific and management personnel; engage specific advisors or clinical research organizations due to conflicts of interest or their capacity constraints; and may also delay recruitment of clinical study sites and study volunteers, any of which may impede progress in our development programs.

We expect any products that we develop and commercialize to compete on the basis of, among other things, efficacy, safety, price and the availability of reimbursement from government or other third-party payers. Our commercial opportunity could be reduced or eliminated if our competitors develop and commercialize products that are viewed as safer, more effective or less expensive than any products that we may develop.

Acute Ischemic Stroke

Currently, there is one approved pharmaceutical treatment for AIS. That treatment is tPA (marketed under the brand name Activase®), and its therapeutic window is limited to up to 4.5 hours after the AIS. There are, however, a number of companies that are actively pursuing a variety of approaches to develop pharmaceutical products for the treatment of AIS including, among others:

● tPA extended treatment window (Genentech / Boehringer Ingelheim)

● RNA aptamer (Basking Biosciences)

● Tenecteplase (Genentech / Boehringer Ingelheim)

● Cell protection and anti-inflammation (ZZ Biotech LLC)

● Neuroprotector (Mitsubishi)

● TS23 (Translational Sciences)

● Solvateltide (Pharmazz)

● Sanbexin (Simcere)

● Asundexian (Bayer)

● Milvexian (Janssen/BMS)

There is a large unmet therapeutic need for AIS treatments that can be administered beyond the 4.5-hour time window of tPA. With this large unmet therapeutic need, there is significant competition to develop new therapeutic options. Currently, the most advanced treatment for AIS uses a medical device for the mechanical removal of blood clots in the large arteries supplying blood to the brain through sophisticated catheter-based approaches, referred to as mechanical thrombectomy. According to published research, use of mechanical thrombectomy is growing and the window of time after a stroke where the procedure can be used is widening. New therapeutic options in development include tissue protection focused therapies (deliverable from hours to days after the stroke) that are intended to preserve and protect brain cells beyond the tPA therapeutic window. The goal is to provide treatment options for the vast majority of AIS patients who do not receive hospital care early enough to qualify for tPA therapy. We believe there is a very significant market opportunity for a drug that has a therapeutic window beyond that of tPA and is able to obtain regulatory approval.

Preeclampsia

There are currently no FDA-approved treatments for preeclampsia and only a limited number of therapeutics in development. Metformin, an established treatment for type 2 diabetes that improves insulin sensitivity and lowers glucose levels, is being studied in late-stage clinical trials in South Africa and Sweden but not in the United States. CBP-4888, a short interfering RNA (siRNA) targeting sFlt-1, is being developed by Comanche Biopharma. It has completed healthy volunteer studies and is expected to be studied in the treatment of pregnant patients with preeclampsia in the future.

DM199 Clinical Trials

AIS Phase 2/3 ReMEDy2 Trial

We are currently conducting our ReMEDy2 clinical trial of DM199 for the treatment of AIS. Our ReMEDy2 clinical trial is a Phase 2/3, adaptive design, randomized, double-blind, placebo-controlled trial intended to enroll approximately 300 participants at up to 100 sites globally. The adaptive design component includes an interim analysis by our independent data safety monitoring board after the first 200 participants have completed the trial. Based on the results of the interim analysis, the study may be stopped for futility, or the final sample size will be determined, ranging between 300 and 728 patients, according to a pre-determined statistical plan. Patients enrolled in the trial will be treated with either DM199 or placebo within 24 hours of the onset of AIS symptoms. The trial excludes patients who received mechanical thrombectomy or participants with large vessel occlusions in the intracranial carotid artery or the M1 segment for the middle cerebral, vertebral or basilary arteries or those that are otherwise eligible for MT. As a result of our recent protocol amendment, participants treated with tPA or TNK, (thrombolytic agents) intended to dissolve blood clots, are now eligible for participation if they continue to experience a persistent neurological deficit after receiving thrombolytic treatment and meet all other trial criteria, including repeat brain imaging to assess any hemorrhagic (bleeding) transformation. The study population is representative of the approximately 80% of AIS patients who do not have treatment options today, primarily due to the limitations on treatment with tPA/TNK and/or MT. We believe that the ReMEDy2 trial has the potential to serve as a pivotal registration study of DM199 in this patient population.

The primary endpoint of the ReMEDy2 trial is physical recovery from stroke as measured by the well-established modified Rankin Scale at day 90. The mRS is a commonly used scale for measuring the degree of disability or dependence in the daily activities of people who have suffered a stroke. Secondary endpoints for the trial will evaluate, among other things, mRS shift (which shows the treatment effect on participants across the full spectrum of stroke severity), participant deaths, the National Institute of Health Stroke Score (NIHSS), Barthel Index (BI) stroke scales, and stroke recurrence. Recurrent strokes represent 25% of all ischemic strokes, often occurring in the first few weeks after an initial stroke and are typically more disabling, costly and fatal than initial strokes.

In July 2022, we announced that the FDA placed a clinical hold on the investigational new drug application (IND) for our Phase 2/3 ReMEDy2 trial. The clinical hold was issued following us voluntarily pausing participant enrollment in the trial to investigate three unexpected instances of clinically significant hypotension (low blood pressure) occurring shortly after initiation of the IV dose of DM199. In September 2022, we submitted our analysis of the events leading to and causing the hypotensive events and proposed protocol modifications to address the mitigation of these events for future trial participants. Following review of this analysis, the FDA informed us that they were continuing the clinical hold and requesting, among other items, an additional in-use in vitro stability study of the IV administration of DM199, which includes testing the combination of the IV bag, IV tubing and mechanical infusion pump, to further rule out any other cause of the hypotension events. The requested in-use study was completed at an independent laboratory and the results were substantially consistent with our earlier testing of the IV bags. In May 2023, these additional supporting data were submitted to the FDA in our clinical hold response. In June 2023, the FDA completed review of our clinical hold response and informed us that the clinical hold was removed, allowing us to resume our Phase 2/3 ReMEDy2 trial.

Prior to the clinical hold of our ReMEDy2 trial, we had experienced and are now continuing to experience slower than expected site activations and enrollment in our ReMEDy2 trial. We believe these conditions may be due to hospital and medical facility staffing shortages; inclusion/exclusion criteria in the study protocol; concerns managing logistics and protocol compliance for participants discharged from the hospital to an intermediate care facility; concerns regarding the prior clinically significant hypotension events and circumstances surrounding the previous clinical hold; and competition for research staff and trial subjects due to other pending stroke and neurological trials. We continue to reach out to current and potential study sites to understand the specific issues at each study site. In an effort to mitigate the impact of these factors, we have significantly expanded our internal clinical team and have brought in-house certain trial activities, including site identification, qualification and activation, clinical site monitoring and overall program management. In addition, we made the decision to globally expand the trial; and to this end, we have submitted or are in the process of preparing regulatory filings and identifying and engaging study sites in the countries of Canada, Australia and Georgia; and we are conducting feasibility assessments in an additional seven European countries. We also recently revised the study protocol to widen the inclusion criteria and reduce the burden on participants and sites. We continue to work closely with our contract research organizations and other advisors to develop procedures to support both U.S. and global study sites and potential participants as needed. We intend to continue to monitor the results of these efforts and, if necessary, implement additional actions to mitigate the impact of these factors on our ReMEDy2 trial; however, no assurances can be provided as to the success of these mitigation actions and if or when these issues will resolve. The failure to resolve these issues will result in delays in our ReMEDy2 trial.

In September 2021, the FDA granted Fast Track designation to DM199 for the treatment of AIS. The FDA may grant Fast Track designation to a drug that is intended to treat a serious condition and nonclinical or clinical data demonstrate the potential to address unmet medical need. The FDA provides opportunities for frequent interactions with the review team for a Fast Track product, including end-of-Phase 2 meetings with the FDA to discuss study design, extent of safety data required to support approval, dose-response concerns, and use of biomarkers. A Fast Track product may also be eligible for rolling review, where the FDA reviews portions of a marketing application before the sponsor submits the complete application.

Phase 1C Open Label Safety Trial

Concurrently with performing the requested in-use study to lift the prior clinical hold, we also conducted a Phase 1C open label, single ascending dose (SAD) study of DM199 administered with the PVC IV bags used in the ReMEDy2 trial. The purpose of the study was to confirm, with human data, the DM199 blood concentration levels achieved with the IV dose and further evaluate safety and tolerability. This study was conducted in Australia. The third cohort, which received the 0.50 μg/kg dose level used in the ReMEDy2 trial, was dosed in April 2023 with no significant adverse events related to DM199. The pharmacokinetic data, including the DM199 blood concentration levels, for all cohorts was included as supplemental information in our clinical hold response to the FDA. In investigating the cause of the unexpected instances of hypotension, we noted that all three participants were receiving ACEi therapy at the time of their enrollment. Given this, we also completed an additional, fourth cohort of hypertensive patients (Part B) being treated with ACEi prior to enrolling. All ACEi patients received the full IV dose at the 0.5 μg/kg level with no instances of hypotension. We believe that these results provide further assurance to investigators in our ReMEDy2 trial that ACEi patients may be safely included in the ReMEDy2 trial.

AIS Phase 2 ReMEDy1 Trial

In May 2020, we announced top-line data from our Phase 2 ReMEDy1 trial assessing the safety, tolerability and markers of therapeutic efficacy of DM199 in patients suffering from AIS. We initiated treatment in this trial in February 2018 and completed enrollment in October 2019 with 92 participants. The study drug (DM199 or placebo) was administered as an IV infusion within 24 hours of stroke symptom onset, followed by subcutaneous injections later that day and once every 3 days for 21 days. The trial was designed to measure safety and tolerability along with multiple tests designed to investigate DM199’s therapeutic potential including plasma-based biomarkers and standard functional stroke measures assessed at 90 days post-stroke. Standard functional stroke measurements include the Modified Rankin Scale, National Institutes of Health Stroke Scale and the Barthel Index. The trial met primary safety and tolerability endpoints and was generally safe and well tolerated. In addition, there was a demonstrated therapeutic effect on the rate of severe stroke recurrence inclusive of all participants and there was also a demonstrated therapeutic effect on the physical recoveries of participants that received tPA prior to enrollment but not in participants receiving mechanical thrombectomy prior to enrollment.

Prior to enrollment, 44 of the 91 evaluable participants (48%) received mechanical thrombectomy intervention, a catheter-based treatment intended to physically remove clots and potentially available for patients who have a large vessel occlusion and can be treated within 6 to 24 hours of the onset of stroke symptoms. While approximately 20% of AIS patients are believed to be eligible for a mechanical thrombectomy, currently only about 5% to 10% receive the treatment due to elapsed time post-stroke or unavailability of the therapy at the hospital where the patient presents. DM199 is intended to treat the approximately 80% of AIS patients who are not eligible for either mechanical thrombectomy or tPA. Treatment for these patients is limited to supportive care. Due to the large volume of participants receiving mechanical thrombectomy prior to enrollment in the ReMEDy1 trial, and a disproportionate distribution of these participants between the active treatment and placebo groups, DM199 did not produce a therapeutic effect on physical recoveries in the overall trial analysis.

When participants treated with mechanical thrombectomy are excluded from the ReMEDy1 trial data set, which represents the group of participants most closely aligned with the target treatment population for DM199 in the ReMEDy2 trial, a positive therapeutic effect on participant physical recoveries was observed. As shown in the table below, when evaluating the participants treated with DM199 (n=25) vs. supportive care and/or tPA (n=21), the results showed that 36% of participants receiving DM199 progressed to a full or nearly full recovery at 90 days (NIHSS: 0-1), compared to 14% of participants in the placebo group. This represents a 22% absolute increase in the proportion of participants achieving a full or nearly full recovery. Additionally, subject deaths decreased from 24% in the placebo group to 12% in the active therapy group, a 50% relative reduction. Note that the number of subjects in these subsets were insufficient for statistical significance.

DM199 vs. Supportive Care and/or tPA

NIHSS Outcomes at 90 Days

In addition, in the evaluable participants (n=91), a significant reduction in the number of participants with recurrent ischemic stroke was noted in the active treatment group: 0 (0%) participants treated with DM199 vs. 6 (13%) on placebo (p=0.012), with 4 of the 6 resulting in participant death.

We believe these findings from our Phase 2 ReMEDy1 trial, which are consistent with the use of Kailikang in China, provide a signal that recombinant human KLK1 appears safe and may have promise as a new treatment for physicians who have limited options for the treatment of patients following an AIS.

CKD Phase 2 REDUX Trial

Our REDUX trial was a multi-center, open-label investigation of participants with mild or moderate chronic kidney disease (Stage II or III) and albuminuria. The trial was conducted in the United States and included three cohorts: non-diabetic, hypertensive African Americans (AA) (n=24); IgA Nephropathy (IgAN) (n=25); and Type 2 diabetics with CKD, hypertension and albuminuria (n=35). The trial evaluated two dose levels of DM199 within each cohort. Study participants received DM199 by subcutaneous (SC) injection twice weekly for 95 days. The primary study endpoints, evaluated after three months of treatment, included safety, tolerability, blood pressure, albuminuria and kidney function, which are evaluated by changes from baseline in estimated glomerular filtration rate, albuminuria, as measured by the urinary albumin to creatinine ratio, and blood pressure in hypertensive participants.

DM199 was generally safe and well tolerated across all cohorts. Adverse events (AEs) were generally mild to moderate in severity, with the most common being local injection site irritation, and all resolved without medical intervention.

DM199 Safety Summary

Intravenously/subcutaneously administered DM199, in doses ranging from 0.025 μg/kg to 50.0 μg/kg, has been administered to over 250 subjects across 5 completed clinical studies and has been shown to be generally safe and well tolerated. The most frequently reported treatment-emergent adverse events in our Phase 2 ReMEDy1 AIS trial were constipation, oral candidiasis and nausea. These events were predominately mild to moderate in severity. Orthostatic hypotension was determined to be the dose limiting tolerability. There have been 3 reported drug-related serious adverse events (SAEs) in subjects receiving DM199 of transient hypotension; these events were rapidly reversible upon stopping infusion with no long term sequelae (further adverse events).

Potential DM199 Commercial Advantages

Several researchers have studied the structural and functional properties of KLK1. This deep body of knowledge has revealed the potential clinical benefits of KLK1 treatments. Today, forms of KLK1 derived from human urine and the pancreas of pigs are approved and sold in Japan, China and South Korea to treat AIS, retinopathy, hypertension and related diseases. We are not aware of any recombinant version of KLK1 with regulatory approval for human use in any country, nor any recombinant version in development other than our drug candidate DM199. We believe at least five companies have attempted, unsuccessfully, to create a recombinant version of KLK1.

The growing understanding of the role of KLK1 in human health and its use in Asia as an approved therapeutic highlight two important potential commercial advantages for DM199:

Moreover, we understand that routine clinical use of KLK1 treatment in Asia has been well-tolerated by patients for several decades. In 2017, we completed a clinical trial comparing the pharmacokinetic profile of DM199 to the human urinary form of KLK1 (Kailikang), which showed DM199, when administered in IV form, had a similar pharmacokinetic profile. Further, when DM199 was administered subcutaneously, DM199 demonstrated a longer acting pharmacokinetic profile, superior to the IV administered Kailikang and DM199.

In addition, we believe that there are also significant formulation, manufacturing, regulatory, and other advantages for recombinant human KLK1 drug candidate DM199:

From a strategic perspective, we continue to believe that strategic alternatives with respect to our DM199 product candidate, including licenses and business collaborations, with other regional and global pharmaceutical and biotechnology companies can be important in advancing the clinical development of DM199. Therefore, as a matter of course and from time to time, we engage in discussions with third parties regarding these matters.

Regulatory Approval

Securing regulatory approval for the manufacture and sale of human therapeutic products in the United States, Europe, Canada and other commercial territories is a long and costly process that is controlled by each territory’s national regulatory agency. The national regulatory agency in the United States is the FDA, in Europe it is the European Medicines Agency (EMA), and in Canada it is Health Canada. Other national regulatory agencies have similar regulatory approval requirements, but each national regulatory agency has its own approval processes. Approval in the United States, Europe or Canada does not assure approval by other national regulatory agencies, although often test results from one country may be used in applications for regulatory approval in another country.

Prior to obtaining regulatory approval to market a therapeutic product, every national regulatory agency has a variety of statutes and regulations which govern the principal development activities. These laws require controlled research and testing of products, governmental review, and approval of a submission containing preclinical and clinical data establishing the safety and efficacy of the product for each use sought, as well as approval of manufacturing facilities, including adherence to good manufacturing practices (GMP) during production and storage, and control of marketing activities, including labeling and advertising.

None of our product candidates have been completely developed or tested; and, therefore, we are not yet in a position to seek regulatory approval in any territory to market any of our product candidates.

The clinical testing, manufacturing, labeling, storage, distribution, record keeping, advertising, promotion, import, export and marketing, among other things, of our current or future product candidates, are subject to extensive regulation by governmental authorities in the United States and other countries. The process of obtaining regulatory approvals and the subsequent compliance with appropriate federal, state, local and foreign statutes and regulations require the expenditure of substantial time and financial resources. Failure to comply with the applicable requirements at any time during the product development process, approval process, or after approval may subject us to a variety of administrative or judicial proceedings, penalties or sanctions, including refusal by the applicable regulatory authority to approve pending applications, withdrawal of an approval, imposition of a clinical hold, issuance of warning letters and other types of letters, product recalls, product seizures, total or partial suspension of production or distribution, injunctions, fines, refusals of government contracts, restitution, disgorgement of profits, or civil or criminal investigations and penalties brought by the FDA and the Department of Justice or other governmental entities.

U.S. Approval Process

In the United States, the FDA is responsible for the review and approval of therapeutic products. The FDA’s mission is to ensure that all therapeutic products on the market are safe and effective. The FDA’s approval process examines and thoroughly reviews potential new therapeutic products and only those that are in compliance with the Food & Drug Cosmetic Act (FDCA) and applicable regulations, are approved.

DM199 is subject to regulatory approval by FDA in the United States because it is a therapeutic product intended for use in humans. The regulatory approval process for DM199 is likely a Biological License Application (BLA) under the Public Health Service Act because DM199 is a recombinant form of the human tissue KLK1 protein. Biological products, like drugs, are used for the treatment, prevention or cure of disease in humans. In contrast to drugs, which are generally chemically-synthesized, biological products are generally derived from living material, and include most protein products intended for therapeutic use. Biological products are considered a subset of drugs and, therefore, also regulated under the FDCA, like drugs. However, the regulatory approval process for a drug is based on a new drug application (NDA) per the drug approval provisions of the FDCA; whereas, the regulatory approval process for a biologic is based on the biological license application (BLA) under the Public Health Service Act.

In addition to regulatory approval, the FDCA and corresponding regulations require licensing of manufacturing facilities, carefully controlled research and testing of products, governmental review and approval of test results prior to marketing of therapeutic products, and adherence to GMP, as defined by each licensing jurisdiction, during production.

A generic description of the different stages in the biologic license application and drug approval process in the United States follows.

Stage 1: Preclinical Research. After an experimental product is discovered, research is conducted to help determine its potential for treating or curing an illness. This is called preclinical research. Animal and/or bench studies are conducted to determine if there are any harmful effects of the product and to help understand how the product works. Information from these experiments is submitted to the FDA as part of an IND. The FDA reviews the information in the IND and decides if the product is safe to study in humans.

Stage 2: Clinical Research. The experimental product is next studied in humans. The studies are known as clinical trials. Clinical trials are carefully designed and controlled experiments in which the experimental product is administered to patients to test its safety and to determine the effectiveness of an experimental product. The four general phases of clinical research are described below.

Stage 3: FDA Review for Approval. Following the completion of Phase 3 clinical studies, the company prepares an electronic common technical document reporting all clinical, nonclinical and chemistry, manufacturing and control studies conducted on the product that is transmitted to the FDA as a Biologics License Application. The FDA reviews the information in the BLA to determine if the product is safe and effective for its intended use. For novel products or those raising significant questions, the FDA may convene an advisory panel meeting regarding the product to allow the FDA to gain feedback from experts. If the FDA determines that the product is safe and effective, the product may be approved and/or subject to additional labeling revisions or post-marketing requirements as a condition of approval.

Stage 4: Marketing. After the FDA has approved the experimental product, the company can make the product available to physicians and their patients. A company also may continue to conduct research to discover new uses for the product. Each time a new use for a product is discovered, the product once again is subject to the applicable FDA approval process before it can be marketed for that purpose.

All FDA approved therapeutic products are subject to continuing regulation by the FDA, including, among other things, record-keeping requirements, reporting of adverse experiences with the product, providing the FDA with updated safety and efficacy information, product sampling and distribution requirements, complying with certain electronic records and signature requirements and complying with FDA guidance documents, and promotion and advertising requirements, which include, among others, standards for direct-to-consumer advertising, promoting products for uses or in patient populations that are not described in the pharmaceutical product’s approved labeling (known as “off-label use”), industry-sponsored scientific and educational activities and promotional activities involving the internet or social media. Failure to comply with FDA requirements is likely to have negative consequences, including adverse publicity, warning or enforcement letters from the FDA or the Federal Trade Commission (FTC), mandated corrective advertising or communications with doctors, product seizures or recalls and state or federal civil or criminal prosecution, injunctions and penalties.

The FDA also may require post-marketing testing, known as Phase 4 testing, risk evaluation and mitigation strategies and surveillance to monitor the effects of an approved product or place conditions on an approval that could restrict the distribution or use of the product.

DM199 may qualify for 4 years of data exclusivity and 12 years of market exclusivity under the BPCIA, which was enacted as part of the ACA, as amended by the Health Care and Education Reconciliation Act of 2010. This means that FDA cannot accept any biosimilar applications based on data from a reference product for a period of four years from the date the reference product was first licensed. Additionally, under the BPCIA, a BLA may provide for 12 years of market exclusivity for a newly approved biologic product. This means FDA cannot approve any biosimilar applications for a period of 12 years from the date the reference product was first licensed. However, the BPCIA provides an abbreviated pathway for the approval of biosimilar and interchangeable biological products. The new abbreviated regulatory pathway establishes legal authority for the FDA to review and approve biosimilar biologics, including the possible designation of a biosimilar as “interchangeable” based on its similarity to an existing brand product. The new law is complex and is only beginning to be interpreted and implemented by the FDA.

European Approval Process

The EMA is roughly parallel to the FDA in terms of the drug approval process and the strict requirements for approval. The EMA was set up in 1995 in an attempt to harmonize, but not replace, the work of existing national medicine regulatory bodies in individual European countries. As with the FDA, the EMA drug review and approval process follows similar stages from preclinical testing through clinical testing in Phase 1, 2, and 3. There are some differences between the FDA and EMA review process, specifically the review process in individual European countries. Such differences may allow certain drug products to be tested in patients at an earlier stage of development.

Other Healthcare Laws and Compliance Requirements

In the United States, our activities are potentially subject to regulation by various federal, state and local authorities in addition to the FDA, including the Centers for Medicare and Medicaid Services and other divisions of the U.S. government, including, the Department of Health and Human Services, the Department of Justice and individual U.S. Attorney offices within the Department of Justice, and state and local governments. For example, if a drug product is reimbursed by Medicare, Medicaid, or other federal or state healthcare programs, a company, including its sales, marketing and scientific/educational grant programs, must comply with the federal Food, Drug & Cosmetic Act (FDCA) as it relates to advertising and promotion of drugs, the federal False Claims Act, as amended, the federal Anti-Kickback Statute, as amended, the Physician Payments Sunshine Act, the federal Health Insurance Portability and Accountability Act of 1996 (HIPAA), and similar state laws. If a drug product is reimbursed by Medicare or Medicaid, pricing and rebate programs must comply with, as applicable, the Medicaid rebate requirements of the Omnibus Budget Reconciliation Act of 1990 (OBRA), and the Medicare Prescription Drug Improvement and Modernization Act of 2003. Among other things, OBRA requires drug manufacturers to pay rebates on prescription drugs to state Medicaid programs and empowers states to negotiate rebates on pharmaceutical prices, which may result in prices for our future products being lower than the prices we might otherwise obtain. Additionally, the ACA substantially changes the way healthcare is financed by both governmental and private insurers. There may continue to be additional proposals relating to the reform of the U.S. healthcare system, in the future, some of which could further limit coverage and reimbursement of drug products. If drug products are made available to authorized users of the Federal Supply Schedule of the General Services Administration, additional laws and requirements may apply.

Pharmaceutical Coverage, Pricing and Reimbursement

In the United States and markets in other countries, sales of any products for which we receive regulatory approval for commercial sale will depend in part on the availability of coverage and adequate reimbursement from third-party payers, including government health administrative authorities, managed care providers, private health insurers and other organizations. In the United States, private health insurers and other third-party payers often provide reimbursement for products and services based on the level at which the government (through the Medicare and/or Medicaid programs) provides reimbursement for such treatments. Third-party payers are increasingly examining the medical necessity and cost-effectiveness of medical products and services in addition to their safety and efficacy; and, accordingly, significant uncertainty exists regarding the coverage and reimbursement status of newly approved therapeutics. In particular, in the United States, the European Union and other potentially significant markets for our product candidates, government authorities and third-party payers are increasingly attempting to limit or regulate the price of medical products and services, particularly for new and innovative products and therapies, which has resulted in lower average selling prices. Further, the increased emphasis on managed healthcare in the United States and on country and regional pricing and reimbursement controls in the European Union will put additional pressure on product pricing, reimbursement and usage, which may adversely affect our future product sales and results of operations. These pressures can arise from rules and practices of managed care groups, judicial decisions and governmental laws and regulations related to Medicare, Medicaid and healthcare reform, pharmaceutical reimbursement policies and pricing in general. As a result, coverage and adequate third party reimbursement may not be available for our products to enable us to realize an appropriate return on our investment in research and product development.

The market for our product candidates for which we may receive regulatory approval will depend significantly on access to third-party payers’ drug formularies or lists of medications for which third-party payers provide coverage and reimbursement. The industry competition to be included in such formularies often leads to downward pricing pressures on pharmaceutical companies. Also, third-party payers may refuse to include a particular branded drug in their formularies or may otherwise restrict patient access to a branded drug when a less costly generic equivalent or another alternative is available. In addition, because each third-party payer individually approves coverage and reimbursement levels, obtaining coverage and adequate reimbursement is a time-consuming and costly process. We would be required to provide scientific and clinical support for the use of any product candidate to each third-party payer separately with no assurance that approval would be obtained, and we may need to conduct expensive pharmacoeconomic studies to demonstrate the cost-effectiveness of our product candidates. This process could delay the market acceptance of any of our product candidates for which we may receive approval and could have a negative effect on our future revenues and operating results. We cannot be certain that our product candidates will be considered cost-effective. If we are unable to obtain coverage and adequate payment levels for our product candidates from third-party payers, physicians may limit how much or under what circumstances they will prescribe or administer them and patients may decline to purchase them. This in turn could affect our ability to successfully commercialize our products and impact our profitability, results of operations, financial condition, and future success.

Research and Development

We have devoted substantially all of our efforts to research and development (R&D), which therefore comprises the largest component of our operating costs. Our primary focus over the past approximately 12 years has been our lead product candidate, DM199, which is currently in clinical development for the treatment of AIS and PE.

We expect our R&D expenses will continue to increase in the future as we continue the development and clinical study of our initial product candidate, DM199, in AIS and PE and seek to pursue other indications or expand our product candidate portfolio. The process of conducting the necessary development and clinical research to obtain regulatory approval is costly and time-consuming; and we consider the active management and development of our clinical pipeline to be integral to our long-term success. The actual probability of success for each product candidate, clinical indication and preclinical program may be affected by a variety of factors including, among other things, the safety and efficacy data for each product candidate, amounts invested in their respective programs, competition and competitive developments, manufacturing capability and commercial viability.

R&D expenses include:

R&D costs are expensed as incurred. Costs for certain development activities, such as clinical trials, are recognized based on an evaluation of the progress to completion of specific tasks using information and data provided to us by our vendors and our clinical sites.

We expect that it will be at least three to four years, if ever, before we have any product candidates ready for commercialization.

Manufacturing

We do not own or operate manufacturing facilities for the production of DM199 nor do we have plans to develop our own manufacturing operations in the foreseeable future. We rely on Catalent Pharma Solutions, LLC (Catalent), a contract development and manufacturing organization (CDMO) with proven GMP experience in the manufacturing of recombinant proteins for clinical trials, for procuring all of our required raw materials and producing active pharmaceutical ingredient for our clinical trials. We have licensed certain gene expression technology and we contract with Catalent for the manufacture of DM199 drug substance. We currently employ internal resources and third-party consultants to manage our manufacturing relationship with Catalent.

Sales and Marketing

We have not yet defined our sales, marketing or product distribution strategy for our initial product candidate, DM199, or any future product candidates. We currently expect to partner with a large pharmaceutical company for sales execution. However, our future commercial strategy may include the use of distributors, a contract sales force or the establishment of our own commercial and specialty sales force, as well as similar strategies for regions and territories outside the United States.

Intellectual Property

We view patents and other means of intellectual property protection, including trade secrets, as an important component of our core business. We focus on translating our innovations into intellectual property protecting our proprietary technology from infringement by competitors. To that end, patents are reviewed frequently and continue to be sought in relation to those components or concepts of our preclinical and clinical products to provide protection. Our strategy, where possible, is to file patent applications to protect our product candidates, as well as methods of manufacturing, administering and using a product candidate. Prior art searches of both patent and scientific databases are performed to evaluate novelty, inventiveness and freedom-to-operate. We require all employees, consultants and parties to a collaborative research agreement to execute confidentiality agreements upon the commencement of employment, consulting relationships or a collaboration with us. These agreements require that all confidential information developed or made known during the course of the engagement with us is to be kept confidential. We also maintain agreements with our scientific staff and all parties contracted in a scientific capacity affirming that all inventions resulting from work performed for us, using our property or relating to our business and conceived or completed during the period covered by the agreement are the exclusive property of DiaMedica.

Our DM199 patent portfolio includes four granted U.S. patents, a granted European patent, a granted Canadian patent, and pending applications in Australia, Canada, China, Europe, India, Japan, South Korea, Hong Kong and the United States. Granted or pending claims offer various forms of protection for DM199, including claims to compositions of matter, pharmaceutical compositions, specific formulations and dosing levels and methods for treating a variety of diseases, including stroke, chronic kidney disease and related disorders. These U.S. patents and applications, and their foreign equivalents, are described in more detail below.

Issued patents held by us cover the DM199 composition of matter based on an optimized combination of closely related isoforms that differ in the extent of glycosylation (process by which sugars are chemically attached to proteins). Issued claims in this patent family cover the most pharmacologically active variants of DM199 and methods of using the same for treating ischemic conditions. These patents are due to expire in 2033. A second patent family includes an issued U.S. patent with claims directed to methods of treating subjects by administering a SC formulation of DM199 or related recombinant kallikrein-1 (KLK1) polypeptides and is predicted to expire in 2033. An additional patent application family is directed to a range of dose levels and dosing regimens of DM199 that are potentially useful for treating a wide range of diseases including, among others, pulmonary arterial hypertension, cardiac ischemia, chronic kidney disease, diabetes, stroke and vascular dementia, which if granted, are predicted to expire in 2038. This family has one issued U.S. patent directed to a range of dose levels for treating ischemic conditions, and is predicted to expire in 2039 because of patent term adjustment.

As previously discussed, we do not own or operate manufacturing facilities for the production of clinical or commercial quantities of DM199. We are contracting with Catalent for the manufacture of DM199. We also license from Catalent certain gene expression technology. Under the terms of this license, certain milestone and royalty payments may become due by us and are dependent upon, among other factors, us performing clinical trials, obtaining regulatory approvals and ultimately the successful commercialization of a new drug, the outcome and timing of which is uncertain. The royalty term is indefinite, but the license agreement may be canceled by us on 90 days’ prior written notice. The license may not be terminated by Catalent unless we fail to make required milestone and royalty payments.

Methods and reagents required for commercial scale manufacture of DM199 are subject to a series of patents issued to Catalent. We license these patents from Catalent, and such license is exclusive as it relates to the production of DM199 or any human KLK1 protein.

We believe that our proprietary technology, along with trade secrets and specialized knowledge of the manufacturing process, will provide substantial protection from third-party competitors. We also believe that DM199 cannot be easily reverse engineered for the production of a copycat version.

We believe that the most relevant granted patents and applications with composition of matter or method of use claims covering DM199 are listed below, along with their projected expiration dates exclusive of any patent term extension:

The base term of a U.S. patent is 20 years from the filing date of the earliest-filed non-provisional patent application from which the patent claims priority. The term of a U.S. patent can be lengthened by patent term adjustment, which compensates the owner of the patent for administrative delays at the U.S. Patent and Trademark Office. In some cases, the term of a U.S. patent is shortened by terminal disclaimer that reduces its term to that of an earlier-expiring patent.

The term of a U.S. patent may also be eligible for patent term extension under the Drug Price Competition and Patent Term Restoration Act of 1984, referred to as the Hatch-Waxman Act, to account for at least some of the time the drug is under development and regulatory review after the patent is granted. With regard to a drug for which FDA approval is the first permitted marketing of the active ingredient, the Hatch-Waxman Act allows for extension of the term of one U.S. patent that includes at least one claim covering the composition of matter of an FDA-approved drug, an FDA-approved method of treatment using the drug, and/or a method of manufacturing the FDA-approved drug. The extended patent term cannot exceed the shorter of five years beyond the non-extended expiration of the patent or 14 years from the date of the FDA approval of the drug. Some foreign jurisdictions, including Europe and Japan, also have patent term extension provisions, which allow for extension of the term of a patent that covers a drug approved by the applicable foreign regulatory agency. In the future, if and when our pharmaceutical products receive FDA approval, we expect to apply for patent term extension on patents covering those products, their methods of use, and/or methods of manufacture.

In addition to patents, we rely on trade secrets and know-how to develop and maintain our competitive position. Companies typically rely on trade secrets to protect aspects of their business that are not amenable to, or that they do not consider appropriate for, patent protection. We protect trade secrets, if any, and know-how by establishing confidentiality agreements and invention assignment agreements with our employees, consultants, scientific advisors, contractors and partners. These agreements provide that all confidential information developed or made known during the course of an individual or entity’s relationship with us must be kept confidential during and after the relationship. These agreements also generally provide that all relevant inventions resulting from work performed for us or relating to our business and conceived or completed during the period of employment or assignment, as applicable, shall be our exclusive property. In addition, we take other appropriate precautions, such as physical and technological security measures, to guard against misappropriation of our proprietary information by third parties.

Employees

As of December 31, 2024, we had 28 employees, 27 of whom were full-time and one of whom was part-time. We have never had a work stoppage and none of our employees are covered by collective bargaining agreements. We believe our employee relations are good.

Risks Related to Our Jurisdiction of Organization

Risks Related to Our Business Model

Our business model assumes we will generate revenue by, among other activities, marketing or out-licensing the product candidates we develop. Since our product candidates are in various stages of development and we have no products approved for commercialization, there is a limited amount of information about us upon which you can base an evaluation of our business and prospects.

None of our product candidates have completed clinical development; and therefore, we have no product candidates approved for commercialization and thus have not begun to market or generate revenues from the commercialization of any product candidates. Because no product candidate has completed clinical development and been approved for commercialization, we have not yet demonstrated an ability to successfully overcome many of the risks and uncertainties frequently encountered by companies in the biopharmaceutical industry. For example, to execute our business plan, we will need to successfully:

● Receive FDA approval and/or approval from similar foreign regulatory bodies;

● Build, maintain, and protect an adequate intellectual property portfolio; and

If we are unsuccessful in accomplishing these objectives, or in making sufficient progress toward these objectives, we may not be able to develop and maintain successful strategic relationships, raise capital, and continue our operations.

We may need to establish relationships with strategic partners to fully develop our product candidates and, if approved, market any product candidates that are approved.

Our business strategy includes securing license agreements and collaborations with other pharmaceutical and biotech companies to support the development of DM199 for various indications. We do not possess all of the financial resources necessary to complete the development of and commercialize our product candidates, if and when they are approved. Unless we expand our own internal sales and marketing capability, we will likely need to make arrangements with other strategic partners to commercialize any product candidates that may be approved. We may not be able to attract such partners, and even if we are able to enter into such partnerships, the terms may be less favorable than anticipated. Further, entering into partnership agreements may limit our commercialization options and would require us to share revenues and profits with our partners. If we do not find appropriate partners, or if such future agreements are not successful, our ability to commercialize products could be adversely affected. Even if we are able to find collaborative partners, the overall success of the commercialization of product candidates in those programs will depend largely on the efforts of those other parties and may be beyond our control and our licensees may elect to assume greater control over these programs. In addition, in the event we pursue our commercialization strategy through collaboration or licenses to third parties, there are a variety of technical, business and legal risks, including, among others:

The occurrence of any of the above events or other related events could impair our ability to generate revenues and harm our business, prospects, operating results and financial condition.

Risks Related to Our Current and Future Clinical Trials and DM199 Product Candidate

We have had and may continue to have difficulty enrolling patients in our ReMEDy2 trial or we may experience other clinical testing delays or setbacks, which would delay our ability or the ability of a future partner to obtain regulatory approval for DM199 to treat AIS and commercialize it, which would substantially harm our business and prospects.

Our ReMEDy2 trial is a Phase 2/3, adaptive design, randomized, double-blind, placebo-controlled trial that is intended to enroll approximately 300 patients at up to 100 sites globally. We have had and may continue to have difficulty enrolling patients in our ReMEDy2 trial, which could delay further completion of the trial or even jeopardize the viability of the trial. We believe these enrollment difficulties may be due, in part, to hospital and medical facility staffing shortages; inclusion/exclusion criteria in the study protocol; concerns managing logistics and protocol compliance for participants discharged from the hospital to an intermediate care facility; concerns regarding the prior clinically significant hypotension events and circumstances surrounding the clinical hold which was lifted in June 2023; use of artificial intelligence and telemedicine which have enabled smaller hospitals to retain AIS patients not eligible for mechanical thrombectomy instead of sending these patients to the larger stroke centers which are more likely to be sites in our trial; and competition for research staff and trial subjects due to other pending stroke and neurological trials. While we have taken several actions to mitigate the impact of these factors adversely affecting our ReMEDy2 trial enrollment rate, such as significantly expanding our internal clinical team and bringing in-house certain trial activities, adopting procedures to support study sites and potential participants as needed, globally expanding the trial, and making certain changes to the study protocol, no assurance can be provided that these actions will lead to increased enrollment. In addition, these actions also involve their own risks.

In addition, it is possible that we may experience other clinical testing delays or setbacks, which would further delay completion of the ReMEDy2 trial. Product development costs typically increase with delays in clinical testing. Significant clinical trial delays could not only extend the time period for obtaining regulatory approval of DM199 to treat AIS and increase our costs, but also shorten any periods during which we or a future partner may have the exclusive right to commercialize DM199 to treat AIS or allow our competitors to bring competitive products to market before us, which would adversely affect the ability to successfully commercialize DM199 and may harm our business, prospects, operating results and financial condition. The ReMEDy2 trial may be delayed for a number of reasons, including without limitation those described above as well as the following:

● patients choosing to participate in competing clinical trials or not at all;

● scheduling conflicts with participating clinicians and clinical sites;

Our product development costs may increase if we need to perform more or larger clinical trials than planned. Additionally, changes in regulatory requirements and policies may occur, and we may need to amend trial protocols or alter our manufacturing processes to reflect these changes. Amendments typically require us to resubmit our trial protocols to the FDA and other regulatory authorities and IRBs or ethics committees, for re-examination, which may impact the cost, timing or successful completion of our ReMEDy2 trial. Delays or increased product development costs or any of these events would likely have a material adverse effect on our business, prospects, operating results and financial condition.

The adaptive design of our ReMEDy2 trial could result in the trial being required to enroll more patients than anticipated, which would increase the time and costs to complete the trial.

Our ReMEDy2 trial is an adaptive design trial intended to enroll approximately 300 patients. The adaptive design component includes an interim analysis by our independent data safety monitoring board after the first 200 participants have completed the trial. Based on the results of the interim analysis, the study may be stopped for futility or a new total sample size may be determined, ranging between 300 and 728 participants, according to a pre-determined statistical analysis plan. Because of the ReMEDy2 trial’s adaptive design, it is possible that the number of participants required to complete the trial may increase significantly from the 300 patients we are currently targeting. If we are required to enroll more participants than currently anticipated, it will increase the time and costs to complete the trial, which may result in a need for additional funding that may not be available to us on acceptable terms, or at all.

The expansion of our DM199 clinical development program into PE involves certain risks related to timing, regulatory approvals, costs and enrollment, and the fact that the PE trial is investigator-sponsored, raises additional risks.

We are currently financially supporting the conduct of a Phase 2 open-label, single center, single-arm, safety and pharmacodynamic, proof-of-concept, investigator-sponsored study of DM199 for the treatment of PE at the Tygerberg Hospital, Cape Town, South Africa. This study may enroll up to 90 women with PE and potentially an additional 30 women with fetal growth restriction may be evaluated. Part 1A top line study results are anticipated in the second quarter of 2025 and are intended to demonstrate whether DM199 is safe and lowers maternal blood pressure. Additionally, patients with early onset PE will be evaluated for improvements in uterine artery dilation, a sign that DM199 is a potentially disease modifying therapy.

The expansion of our DM199 clinical development program into PE and the progress of that program may not occur on the anticipated timeline or at all. In addition, the Phase 2 PE trial may cost us more than we anticipate. Additionally, because the trial is investigator-sponsored, we have less control over the timing and costs of the study and the ability to recruit trial participants than if we conducted the study with our own personnel. There is no guarantee that our physician collaborators will devote adequate time and resources to perform this study and/or maintain adequate clinical trial information regarding our product candidate. If these third parties fail to meet expected deadlines, fail to transfer to us any regulatory information in a timely manner, fail to adhere to the study protocol, or fail to act in accordance with regulatory requirements or our agreement with them, or if they otherwise perform in a substandard manner or in a way that compromises the quality or accuracy of their activities or the data they obtain, then the current PE trial or future clinical trials may be extended or delayed with additional costs incurred, or our data may be rejected by applicable regulatory agencies. Any of these risks could adversely impact our business, prospects, operating results ns and financial position, including our ability to raise additional financing, if and when needed.

DM199 and any other product candidates we choose to develop may cause undesirable side effects or have other properties that could delay or prevent their regulatory approval, limit the commercial profile of an approved label, or result in significant negative consequences following marketing approval, if granted.

As with most pharmaceutical products, DM199 and any future product candidates could be associated with side effects or adverse events, which can vary in severity and frequency. Although the only DM199 related adverse events that have occurred to date in our clinical trials have been constipation, injection site reaction, nausea, headache, flushing and three unexpected instances of clinically significant, but transient, hypotension (low blood pressure), side effects or adverse events associated with the use of DM199, or any future product candidates, may be observed at any time during clinical development. If unacceptable side effects arise in the development of our product candidates, we, the FDA or comparable foreign regulatory authorities, the Institutional Review Boards, or independent ethics committees at the institutions in which our studies are conducted, or the data safety monitoring board, could suspend or terminate our clinical trials, similar to when the FDA imposed a clinical hold on our current ReMEDY2 trial in 2021, or the FDA or comparable foreign regulatory authorities could order us to cease clinical trials or deny approval of our product candidates for any or all targeted indications.

Treatment-related side effects could also affect patient recruitment or the ability of enrolled subjects to complete the trial, or result in potential product liability claims. In addition, these side effects may not be appropriately recognized or managed by the treating medical staff. We may be required to train medical personnel using our product candidates to understand the side effect profiles for our clinical trials. Inadequate training in recognizing or managing the potential side effects of our product candidates could result in patient injury or death. Any of these occurrences may prevent us, or any future partner from achieving or maintaining market acceptance of the affected product candidate and may harm our business, prospects, operating results and financial condition.

Results of our trials could reveal a high and unacceptable severity and prevalence of side effects, toxicity or other safety issues, and could require us to perform additional studies, including preclinical studies, or halt development of DM199 or any future product candidates, or expose us to product liability lawsuits that would likely harm our business. There can be no assurance that we will resolve any issues related to any product-related adverse events to the satisfaction of the FDA or any other regulatory authority in a timely manner, if ever, which could harm our business, prospects, operating results and financial condition.

We are required by the FDA and other comparable foreign regulatory authorities to report certain information about adverse medical events if those products may have caused or contributed to those adverse events. The timing of our obligation to report would be triggered by the date we become aware of the adverse event as well as the nature of the event. We may fail to report adverse events we become aware of within the prescribed timeframe. We may also fail to appreciate that we have become aware of a reportable adverse event, especially if it is not reported to us as an adverse event or if it is an adverse event that is unexpected or removed in time from the use of our products. If we fail to comply with our reporting obligations, the FDA other comparable foreign regulatory authorities could take action including but not limited to criminal prosecution, the imposition of civil monetary penalties, seizure of our products, halting our clinical trials or delay in approval or clearance of future product candidates.

We face the risk of product liability claims, which could exceed our insurance coverage, deplete our cash resources and lead to clinical trial delays.

A risk of product liability claims, and related negative publicity, is inherent in the development of human therapeutics. We are exposed to the risk of product liability claims alleging that use of DM199, or any future product candidate, caused an injury or harm. These claims can arise at any point in the development, testing, manufacture, marketing or, if approved, commercial sale of a product candidate. Such claims may be made directly by patients involved in clinical trials of our product candidate, by consumers, healthcare providers or by individuals, organizations or companies selling our products, if approved. Product liability claims can be expensive to defend, even if the product or product candidate did not actually cause the alleged injury or harm, and could lead to clinical trial delays and could negatively impact existing or future trial enrollment.

Insurance covering product liability claims is expensive. To protect against potential product liability risks, we carry product liability insurance coverage at a level we deem appropriate based upon the current safety profile of DM199 and our stage of development. We may choose or find it necessary to increase our insurance coverage in the future; however, there can be no assurance that such insurance coverage is or will continue to be adequate or available to us at a cost acceptable to us or at all. Any liability for damages resulting from a product liability claim could exceed the amount of our coverage, require us to pay a substantial monetary award from our own cash resources and otherwise have a material adverse effect on our business, operating results and financial condition.

If we are unable to maintain product liability insurance required by third parties, certain agreements, such as those with clinical trial sites, contract research organizations and other supporting vendors, would be subject to termination, which could have a material adverse impact on our operations.

Some of our agreements with third parties require, and in the future will likely require, us to maintain product liability insurance in at least certain specified minimum amounts. If we cannot maintain acceptable amounts of coverage on commercially reasonable terms in accordance with the terms set forth in these agreements, the corresponding agreements would be subject to termination, which could have a material adverse impact on our operations.

The PE trial is being conducted in South Africa and we are in the process of globally expanding our ReMEDy2 trial to countries outside the United States, raising additional international risks, which could materially adversely affect our business.

The PE trial is currently being conducted in South Africa and we are in the process of expanding our ReMEDy2 trial to certain non-U.S. countries, including Canada, Australia, Georgia, United Kingdom and certain countries in the European Union. In addition, we plan to seek regulatory approval of DM199, or any future product candidates, outside of the United States. Accordingly, we are subject to risks related to operating in foreign countries including, among others:

● compliance with differing regulatory requirements for drug approvals;

● foreign taxes, including withholding of payroll taxes;

It is possible that the FDA and comparable foreign regulatory authorities may not accept trial data from countries located outside the United States.

The PE trial is being conducted in South Africa and we are in the process of globally expanding our ReMEDy2 trial to countries outside the United States. The acceptance by the FDA or comparable foreign regulatory authority of study data from clinical trials conducted outside the United States or another jurisdiction may be subject to certain conditions or may not be accepted at all. In cases where data from foreign clinical trials are intended to serve as the basis for marketing approval in the United States, the FDA will generally not approve the application on the basis of foreign data alone unless (i) the data are applicable to the U.S. population and U.S. medical practice; (ii) the trials were performed by clinical investigators of recognized competence and pursuant to good clinical practice (GCP) regulations; and (iii) the FDA, or comparable foreign regulatory authority, is able to validate the data through an on-site inspection or other appropriate means. In addition, such foreign trials would be subject to the applicable local laws of the foreign jurisdictions where the trials are conducted. There can be no assurance that the FDA or any comparable foreign regulatory authority will accept data from trials conducted outside of the United States or the applicable jurisdiction. If the FDA or any comparable foreign regulatory authority does not accept such data, it would result in the need for additional participants or trials, which would be costly and time-consuming and delay regulatory approval and commercialization of our DM199 product candidate.

Data from the investigator-sponsored PE trial, which we expect in the second quarter of 2025 and thus earlier than data from our ReMEDy2 trial, may adversely affect our ReMEDy2 trial, which could adversely impact our business, prospects, operating results and financial position and harm our ability to raise additional financing, if and when needed.

Our drug candidate, DM199, is currently in clinical development in two areas, AIS and PE. We anticipate Part 1A topline study results for the Phase 2 PE clinical trial in the second quarter of 2025. Part 1A topline study results are intended to demonstrate whether DM199 is safe for PE patients, lowers blood pressure, and, in early on-set patients, dilates intrauterine arteries to increase placental blood flow. The results from Part 1A of the study may not be consistent with the safety results from our prior trials of DM199 in humans. If the Part 1A topline study results are inconsistent, incomplete or otherwise demonstrate that DM199 is not safe or does not lower blood pressure, our current ReMEDy2 clinical trial of DM199 for the treatment of AIS may be adversely affected. Should this occur, we may be required to repeat clinical or non-clinical studies, our clinical development plans may be significantly delayed, and we may incur additional costs, which could adversely impact our business, prospects, operating results and financial position. Adverse results from the Part 1A topline study also could adversely affect our ability to raise additional financing, if and when needed.

Interim, “topline” and preliminary results from our clinical trials that we announce or publish from time to time may change as more data become available and are subject to audit and verification procedures that could result in material changes in the final data.

From time to time, we may publish interim, topline or preliminary results from our clinical trials. We anticipate Part 1A topline study results for the Phase 2 PE clinical trial in the second quarter of 2025. Interim results from clinical trials are subject to the risk that one or more of the reported clinical outcomes may materially change as participant enrollment continues and more participant data become available. Preliminary or topline results also remain subject to audit and verification procedures that may result in the final data being materially different from the preliminary data we previously published. As a result, interim and preliminary data should be viewed with caution until the final data are available. Differences between preliminary, topline or interim data and final data could significantly harm our business and prospects and may cause the trading price of our common shares to fluctuate significantly. We also make estimations, calculations and conclusions as part of our analyses of data, and we may not have received or had the opportunity to fully and carefully evaluate all data. As a result, the topline results that we report may differ from future results of the same studies, or different conclusions or considerations may qualify such results, once additional data have been received and fully evaluated.

Further, others, including regulatory authorities, may not accept or agree with our estimates, calculations, conclusions or analyses or may interpret or weigh the importance of data differently, which could impact the value of the particular development program, the approvability or commercialization of the particular product candidate or our Company in general. In addition, the information we choose to publicly disclose regarding a particular study or clinical trial is based on what is typically extensive information, and others may not agree with what we determine is the material or otherwise appropriate information to include in our disclosure. Any information we determine not to disclose may ultimately be deemed meaningful by others with respect to future decisions, conclusions, views, activities or otherwise regarding a particular product candidate or our business. If the interim, topline or preliminary data that we report differ from actual results, or if others, including regulatory authorities, disagree with the conclusions reached, our ability to obtain approval for, and commercialize, product candidates may be harmed, which could significantly harm our business and prospects.

If our ReMEDy2 trial fails to adequately demonstrate the safety and efficacy of DM199 to treat AIS or if the PE trial fails to adequately demonstrate the safety and initial signs of efficacy of DM199 to treat PE, we will not be able to obtain required regulatory approvals, which would substantially harm our business, prospects and financial condition.

Before obtaining marketing approval from the FDA and other comparable foreign regulatory authorities for the sale of DM199 to treat AIS or the approval to continue testing DM199 as a treatment for PE, we must demonstrate the safety and efficacy of DM199 to treat AIS or PE to a level acceptable to the FDA or similar regulatory bodies in other jurisdictions. Clinical testing is expensive, difficult to design and implement, can take many years to complete, and has uncertain outcomes. The outcome of early clinical trials may not predict the success of later clinical trials, and the interim results of ReMEDy2 and the results of the PE trial may not necessarily predict final results. A number of companies in the pharmaceutical and biotechnology industries have suffered significant setbacks in advanced clinical trials due to lack of efficacy or unacceptable safety profiles, including the emergence of undesirable side effects, notwithstanding promising results in earlier trials. We do not know whether our ReMEDy2 trial by itself will demonstrate adequate efficacy and safety to support regulatory approvals to market DM199 to treat AIS in the United States, or in any other jurisdiction, or that a second confirmatory trial will be required. A product candidate may fail for safety or efficacy reasons at any stage of the testing process. In addition, the patient population in our ReMEDy2 trial often have co-morbidities that may cause severe illness or death, which may be attributed to DM199 in a manner that negatively affects the safety profile of our DM199 product candidate. If the results of our ReMEDy2 trial are inconclusive with respect to efficacy, if we do not meet our clinical endpoints with statistical significance or if there are unanticipated safety concerns or adverse events that emerge during the ReMEDy2 trial, the PE trial or other clinical trials, such as the events that caused the FDA to place the prior clinical hold on the IND for our ReMEDy2 trial, we may be prevented from or delayed in obtaining marketing approval, and even if we obtain marketing approval, any sales of DM199 for the treatment of AIS may be limited.

We may be required to suspend, repeat or terminate our clinical trials if they are deemed not conducted in accordance with regulatory requirements, the results are negative or inconclusive, or the trial is not well designed.

Clinical trials must be conducted in accordance with the FDA’s current Good Clinical Practice (cGCP) requirements, or comparable requirements of applicable foreign regulatory authorities, and provide statistically significant evidence predictive of patient benefit. Clinical trials are subject to oversight by the FDA and other foreign governmental agencies, and IRBs or ethics committees at the trial sites where the clinical trials are conducted. In addition, clinical trials must be conducted with product candidates produced in accordance with applicable GMP requirements. Clinical trials may be suspended by us or by the FDA, other foreign regulatory authorities, or by an IRB or ethics committee with respect to a particular clinical trial site, for various reasons, including:

● deficiencies in the clinical trial operations or trial sites;

● deficiencies in the trial design necessary to demonstrate efficacy;

The design and implementation of clinical trials is a complex process. As a Company, we have limited experience designing and implementing clinical trials. We may not successfully or cost-effectively design and implement clinical trials that achieve our desired clinical endpoints. A clinical trial that is not well designed or that yields unforeseen adverse side effects or undue risks to trial subjects may delay or even prevent initiation of the trial, can lead to increased difficulty in site activations and enrolling patients, may make it more difficult to obtain regulatory approval for the product candidate on the basis of the trial results or, even if a product candidate is approved, could make it more difficult to commercialize the product successfully or obtain reimbursement from third party payers. Additionally, a trial that is not well designed or that yields unforeseen adverse side effects or undue risks to trial subjects could be delayed and more expensive than it otherwise would have been, or we may incorrectly estimate the costs to complete the clinical trial, which could lead to a shortfall in funding. We can provide no assurance that our ReMEDy2 trial, the PE trial or any other clinical trial conducted or sponsored by us has been or will be designed and implemented successfully or achieve its desired clinical endpoints.

Our prospects depend on the clinical and commercial success of our DM199 product candidate.

We are highly dependent on the success of DM199 and we, or a future partner, may not be able to successfully obtain regulatory or marketing approval for, or successfully commercialize, this product candidate. To date, we have expended significant time, resources, and effort on the development of DM199, including conducting preclinical and clinical trials, for the treatment of AIS and cardio renal disease. DM199 requires significant additional clinical testing and investment prior to seeking marketing approval. A commitment of substantial resources by us and any potential partner or collaborator to continue to conduct the clinical trials for DM199 will be required to obtain required regulatory approvals and successfully commercialize this product candidate. Although we intend to study the use of DM199 to treat multiple diseases, we have no other product candidates in our current clinical development pipeline, with the exception of our new second candidate, DM300, which is in the early, preclinical stage of development and is intended to treat other inflammatory diseases, such as acute pancreatitis. The ability of us or a future partner to generate revenue from product sales and to achieve commercial success with DM199 will depend almost entirely on our ability to demonstrate sufficient safety and efficacy to obtain regulatory approval for DM199. We may fail to complete required clinical trials successfully and not be able to obtain regulatory approvals or commercialize DM199. Competitors may develop alternative products and methodologies to treat the diseases or indications that we are pursuing, thus reducing or eliminating the anticipated competitive advantages of DM199. We do not know whether any of our product development efforts will prove to be effective, meet applicable regulatory standards required to obtain marketing approval, be capable of being manufactured at a reasonable cost, or be successfully marketed. DM199 is not expected to be commercially viable for at least three or four years. In addition, although the only DM199 related adverse events that have occurred to date in our clinical trials have been constipation, injection site reaction, nausea, headache and three unexpected instances of clinically significant, but transient, hypotension (low blood pressure), it is possible that DM199 may be observed to cause undesirable side effects. If regulatory authorities do not approve DM199 for the treatment of AIS, PE or any other indications, or if we fail to maintain regulatory compliance, we, or a future partner, would be unable to commercialize DM199 and our business, prospects, operating results and financial condition would be harmed. If we do succeed in developing viable products from DM199, we will face many potential future obstacles, such as the need to develop or obtain manufacturing, sales and marketing, and distribution capabilities, if we do not partner with a third party to provide these functions.

Risks Related to Our Financial Position and Need for Additional Capital

Since we currently have no revenue from product sales and do not expect any revenue from product sales for at least three or four years, we will need additional funding to continue our clinical development activities and other operations, which may not be available to us on acceptable terms, or at all.

We expect we will need substantial additional capital to further our R&D activities, planned clinical trials and regulatory activities and to otherwise develop our DM199 product candidate to a point where it may be commercially sold. We expect our current cash resources of $44.1 million in cash, cash equivalents and marketable securities as of December 31, 2024 to be sufficient to allow us to continue our Phase 2/3 trial in patients with AIS, the PE trial and to otherwise fund our planned operations for at least the next 12 months from the date of issuance of the financial statements included in this report. However, the amount and timing of our future funding requirements will depend on many factors, including, among others:

● the costs related to general and administrative support.

We may require significant additional funds earlier than we currently expect, and there is no assurance that we will not need or seek additional funding prior to such time. We may elect to raise additional funds even before we need them if circumstances or market conditions for raising additional capital are favorable.

Since our inception, we have financed our operations primarily from public and private sales of equity securities, the exercise of warrants and stock options, interest income on funds available for investment and government grants and tax incentives. We expect to continue this practice for the foreseeable future. We do not have any existing credit facilities under which we could borrow funds. We may seek to raise additional funds through various sources, such as equity and debt financings, or through strategic collaborations and license agreements. We can give no assurances that we will be able to secure additional sources of funds to support our operations, or if such funds are available to us, that such additional financing will be sufficient to meet our needs or on terms acceptable to us. This is particularly true if we experience additional adverse events, if our clinical data is not positive, or economic and market conditions deteriorate.

Although we previously have been successful in obtaining financing through our equity securities offerings, there can be no assurance that we will be able to do so in the future. To the extent we raise additional capital through the sale of equity or debt securities, the ownership interests of our shareholders will be diluted. Debt financing, if available, may involve agreements that include conversion discounts or covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. If we raise additional funds through government or other third-party funding, marketing and distribution arrangements or other collaborations or strategic alliances or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates or grant licenses on terms that may not be favorable to us. It is possible that financing will not be available or, if available, may not be on favorable terms. The availability of financing could be affected by many factors, including, among others:

● the results of our clinical trials and other scientific and clinical research;

● our ability to obtain regulatory approvals;

● market acceptance of DM199 or any future product candidates;

● the status of strategic alliance agreements; and

● other relevant commercial considerations.

If adequate funding is not available, we may be required to implement cost reduction strategies; delay, reduce or eliminate one or more of our product development programs; relinquish significant rights to DM199 or future product candidates; obtain funds on less favorable terms than we would otherwise accept; and/or divest assets or cease operations through a merger, sale or liquidation of our Company.

We have incurred substantial losses since our inception and expect to continue to incur substantial losses for at least three or four years and may never achieve or sustain profitability.

We are a clinical stage biopharmaceutical company focused on the development of our DM199 product candidate. Investment in biopharmaceutical product development is highly speculative because it entails substantial upfront financial expenditures and significant risk that a product candidate will fail to prove effective, gain regulatory approval or become commercially viable. We do not have any products approved by regulatory authorities and have not generated any revenues from product sales to date, and do not expect to generate any revenue from the sale of products for at least three or four years. We have incurred significant R&D and G&A expenses related to our ongoing operations and expect to continue to incur such expenses. As a result, we have incurred significant operating losses in every reporting period since our inception and we may never achieve or sustain profitability. For the years ended December 31, 2024 and 2023, we incurred a net loss of $24.4 million and $19.4 million, respectively. As of December 31, 2024, we had an accumulated deficit of $140.0 million. Our prior losses, combined with expected future losses, have had and will continue to have an adverse effect on our shareholders’ equity and working capital. We expect to continue to incur substantial operating losses as we continue our R&D activities, planned clinical trials, including our Phase 2/3 ReMEDy2 trial and the PE trial, regulatory activities and other administrative expenses and to support the development of DM199 or any future product candidate to a point where it can be out-licensed or receives required regulatory approvals and may be commercially sold and we begin to recognize future product sales, or receive royalty payments, licensing fees and/or milestone payments sufficient to generate revenues to fund our continuing operations. We expect our operating losses to increase in the near term as we continue development of DM199 and the clinical trials required to seek regulatory approval for DM199, or any future product candidate. We are unable to predict the extent of any future losses or when we will become profitable, if ever. Our failure to achieve and sustain profitability may depress the market price of our common shares and could impair our ability to raise capital, continue to develop DM199, or any future product candidate, expand our business and product offerings or continue our operations. Even if we do achieve profitability, we may not be able to sustain or increase profitability on an ongoing basis.

Risks Related to Governmental and Regulatory Compliance and Approvals

The regulatory approval process is expensive, time-consuming and uncertain and may prevent us or any future partner or collaborator from obtaining approvals for the commercialization of DM199 or any future product candidate.

The process of obtaining marketing approvals, both in the United States and abroad, is expensive and may take many years, if approval is obtained at all, and can vary substantially based upon a variety of factors, including the type, complexity and novelty of the product candidate involved. Our DM199 or any future product candidate, and the activities associated with their development and commercialization, including design, research, testing, manufacture, quality control, recordkeeping, labeling, packaging, storage, advertising, promotion, sale, distribution, import, export and reporting of safety and other post-market information, are subject to comprehensive regulation by the FDA, the EMA and other similar foreign regulatory agencies. Failure to obtain marketing approval for DM199 or any future product candidate will prevent us or any future partner or collaborator from commercializing the product candidate. We have only limited experience in filing and supporting the applications necessary to gain marketing approvals and expect to rely on a future partner, collaborator or third-parties to assist us in this process. Securing marketing approval requires the submission of extensive preclinical and clinical data and supporting information to regulatory authorities for each therapeutic indication to establish the product candidate’s safety and efficacy. Securing marketing approval also requires the submission of information about the product manufacturing process to, and inspection of manufacturing facilities by, the regulatory authorities. The FDA, EMA or other regulatory authorities may determine that DM199 or any future product candidate may not be effective, may be only moderately effective or may prove to have undesirable or unintended side effects, toxicities or other characteristics that may preclude our obtaining marketing approval or prevent or limit its commercial use. One issue of which we are aware is that because the plastic bags we use in the IV administration of DM199 are made of PVC, certain countries have banned or limited the use of PVC in a manner that may limit our ability to conduct the trials in such countries, or in the future in the event we are able to obtain required regulatory approvals, may limit the salability of DM199 in certain countries, thereby decreasing our worldwide market opportunity. Additionally, the regulatory approval process and requirements can change substantially based on amendments to federal regulations, new or amended FDA guidance documents governing the regulatory approval process, and even changes in FDA approval priorities based on the government administration as was recently seen in response to the COVID-19 pandemic. As a result, any marketing approval we ultimately obtain may be limited or subject to restrictions or post-approval commitments that render the approved product not commercially viable. Our or any future partner’s inability to obtain regulatory approval for DM199 or any future product candidate, or if such approval is limited, could substantially harm our business.

Any product candidate for which we or any future partner or collaborator obtains marketing approval could be subject to post-marketing restrictions or recall or withdrawal from the market, and we may be subject to penalties if we fail to comply with regulatory requirements or if we experience unanticipated problems with the product candidate.

The FDA and other federal and state agencies, including the U.S. Department of Justice (DOJ), closely regulate compliance with all requirements governing prescription drug products, including requirements pertaining to marketing and promotion of drugs in accordance with the provisions of the approved labeling and manufacturing of products. The FDA and DOJ impose restrictions on manufacturers’ communications regarding off-label use, , sales and marketing activities, transparency laws, and reimbursement obligations, which restrictions can change substantially based on new and/or amended government interpretations of regulatory priorities, new and/or amended federal regulations, and other external forces. If we do not market our products for approved indications, we may be subject to enforcement action for off-label marketing. Violations of such requirements may lead to investigations alleging violations of the FDCA and other statutes, including the federal False Claims Act, the federal Anti-Kickback Statute, the Sunshine Act and other federal and state health care fraud and abuse laws, as well as state consumer protection laws.

Our or any future partner’s failure to comply with all regulatory requirements, or the later discovery of previously unknown adverse events or other problems with our products, manufacturers or manufacturing processes, may yield various results, including:

● litigation involving patients using our products;

● restrictions on such products, manufacturers or manufacturing processes;

● restrictions on the labeling or marketing of a product;

● restrictions on product distribution or use;

● requirements to conduct post-marketing studies or clinical trials;

● warning or untitled letters;

● withdrawal of the products from the market;

● recall of products;

● fines, restitution or disgorgement of profits or revenues;

● suspension or withdrawal of marketing approvals;

● damage to relationships with any then current or potential partners;

● refusal to permit the import or export of our products;

● product seizure; or

● injunctions or the imposition of civil or criminal penalties.

Non-compliance by us or any future partner or collaborator with regulatory requirements regarding ongoing safety monitoring, or pharmacovigilance, and with requirements related to the development of products, can also result in significant financial penalties. Similarly, failure to comply with regulatory requirements regarding the protection of personal information can also lead to penalties and sanctions.

We may be unable to obtain FDA acceptance of INDs to commence future clinical trials in the United States or on the timelines we expect, and even if we are able to, the FDA may not permit us to proceed in a timely manner.

Prior to commencing additional clinical trials in the United States for DM199 or any future product candidate, we will be required to have an accepted IND for each product candidate and for each targeted indication. In April 2021, we filed, and in May 2021, the FDA accepted, an IND for the Phase 2/3 ReMEDy2 trial in patients with AIS. However, in July 2022, the FDA imposed a clinical hold on the IND under which we are conducting our Phase 2/3 ReMEDy2 trial, which clinical hold was subsequently lifted in June 2023. If the Phase 2 IST study of DM199 in PE is successful, we plan to file an IND to enable us to commence additional clinical trials studying DM199 for the treatment of PE. There is no assurance that this IND will be filed on a timely basis or accepted by the FDA on a timely basis or at all. A submission of an IND may not necessarily result in the FDA allowing further clinical trials to begin and, once begun, issues, such as clinical holds, may arise that will require us to suspend or terminate such clinical trials. Additionally, even if relevant regulatory authorities agree with the design and implementation of the clinical trials set forth in an IND, these regulatory authorities may change their requirements in the future. Failure to obtain acceptance of any future INDs may cause the development of DM199 or any future product candidate to be delayed or terminated, which could materially and adversely affect our business and prospects.

We have received Fast Track designation for DM199 for the treatment of AIS, and we may seek such designation for other uses of DM199 or future product candidates. Fast Track designation may not lead to faster development or a faster FDA review or approval process, and it does not increase the likelihood that DM199 will receive marketing approval in the United States. Further, there is no guarantee we will be able to maintain such designation.

In September 2021, we received Fast Track designation from the FDA for DM199 for the treatment of AIS where tPA and/or mechanical thrombectomy are not indicated or medically appropriate. The FDA may grant Fast Track designation to a drug that is intended to treat a serious condition and nonclinical or clinical data demonstrate the potential to address unmet medical need. The FDA provides opportunities for more frequent interactions with the review team for a Fast Track product, including pre-IND meetings, end-of-phase 1 meetings and end-of-phase 2 meetings with the FDA to discuss study design, extent of safety data required to support approval, dose-response concerns and use of biomarkers. A Fast Track product may also be eligible for rolling review, where the FDA reviews portions of a marketing application before the sponsor submits the complete application.
