DiaMedica Therapeutics Inc. (NASDAQ:DMAC), a clinical-stage biopharmaceutical company focused on developing novel treatments for severe ischemic diseases, today provided a business update and financial results for the quarter ended September 30, 2024. Management will host a conference call Thursday, November 14, 2024, at 8:00 AM Eastern Time / 7:00 AM Central Time to discuss its business update and third quarter 2024 financial results.

Updates to ReMEDy2 Acute Ischemic Stroke (AIS) Phase 2/3 Protocol and Statistical Analysis Plan

Following in-depth discussions of the ReMEDy2 trial with current and prospective investigators, stroke experts and its scientific advisory board, the Company has made certain additional updates to the protocol intended to enhance the probability of success for the trial, principally through two modifications: broadening the trial population to include patients not responding to thrombolytic treatment (tissue plasminogen activator (tPA) or tenecteplase (TNK)) and increasing the sample size of the planned interim analysis. These changes were submitted the United States Food and Drug Administration (FDA) on August 30, 2024, and as no FDA comments have been received to-date, the Company is proceeding with implementation..

The first modification of expanding the trial population will capture patients expected to demonstrate a strong treatment response with a low placebo response, potentially enhancing the primary outcome measure for the ReMEDy2 trial. These patients are considered "non-responders" if they receive thrombolytic therapy but retain a persistent neurologic deficit, meaning that their stroke symptoms do not improve, six or more hours following administration of the thrombolytic. In the Company's prior ReMEDy1 Phase 2 stroke trial, the subgroup of patients who received tPA (n=20) prior to enrollment showed the highest response rate of any group, with these patients receiving DM199 or placebo an average of 13.5 hours post-tPA administration, indicating that the participants did have a persistent neurological deficit prior to randomization. The Company further notes that including these patients has the potential to significantly accelerate enrollment.

The second modification follows additional statistical modeling of the adaptive design study whereby the interim analysis will be conducted when 200 subjects are treated instead of the previously proposed sample size of 144 subjects. The incremental increase in sample size is intended to increase the precision of the algorithm used to determine the final overall sample size, which we expect will reduce the total number of participants required for the study, thereby reducing the overall trial timeline and trial cost. DiaMedica plans to submit an amended statistical analysis plan (SAP) to the FDA for confirmatory comments.

Together, these protocol and SAP changes are intended to increase the probability of success for the ReMEDy2 trial and expedite overall completion of the study, with potential for a reduced sample size and cost savings.

ReMEDy2 Phase 2/3 Clinical Update

Progress continues with the ReMEDy2 trial site activation activities. The majority of the Company's priority research sites in the United States have been activated. These sites are anticipated to be top enrollment centers for the ReMEDy2 trial and are expected to enroll a disproportionately large share of participants in the trial. DiaMedica recently received approval from Health Canada to conduct the ReMEDy2 trial in Canada and is on track to commence site activations in Canada by the end of the year.

With the adoption of an increased sample size for the interim analysis, the Company now anticipates top line interim results in Q4 2025 compared to the Company's previous guidance of Summer 2025. Patient recruitment will continue while the first 200 participants complete their participation in the trial and the interim analysis is conducted.

"The inclusion of thrombolytic non-responders significantly expands the pool of eligible patients with potential for observing increased treatment responses," stated Dr. Lorianne Masuoka, DiaMedica's Chief Medical Officer. "As we near the completion of activating our high-volume centers, this is expected to catalyze further enrollment momentum."

Preeclampsia Phase 2 Investigator-Sponsored Trial

DM199 is being developed as a disease-modifying treatment to safely extend gestation and improve fetal and maternal outcomes in preeclampsia (PE). DM199's mechanism of action has the potential to lower blood pressure, enhance endothelial health and improve perfusion to maternal organs and the placenta. On October 9, 2024, DiaMedica announced the receipt of regulatory approval from the South African Health Products Regulatory Authority (SAHPRA) to initiate an investigator-sponsored trial (IST) of DM199 in PE. As reported earlier today, the first patient has been enrolled in the Part 1A dose escalation portion of the Phase 2 study. Top line results from Part 1A are anticipated in the first half of 2025.

The Phase 2 IST is an open-label, single center, single-arm, safety and pharmacodynamic, proof-of-concept study of DM199 for the treatment of PE conducted at the Tygerberg Hospital, Cape Town, South Africa. Up to 90 women with PE, and potentially an additional 30 subjects with fetal growth restriction, may be evaluated. Part 1 of the PE study is recruiting women planned for delivery within 72 hours and Part 2 will recruit women in the expectant management setting. Key outcomes from Part 1 are safety, tolerability, identifying whether DM199 crosses the placental barrier and two efficacy signals of interest to DiaMedica: (1) change in maternal systolic blood pressure (SBP) after infusion and (2) improved baseline uterine artery blood flow.

Balance Sheet and Cash Flow

DiaMedica reported total cash, cash equivalents and investments of $50.2 million, current liabilities of $4.3 million and working capital of $46.5 million as of September 30, 2024, compared to total cash, cash equivalents and investments of $52.9 million, current liabilities of $2.8 million and working capital of $50.9 million as of December 31, 2023. The decreases in combined cash, cash equivalents and marketable securities and in working capital are due to the net cash used in operating activities partially offset by the net proceeds received from DiaMedica's June 2024 private placement.

Net cash used in operating activities for the nine months ended September 30, 2024 was $15.6 million compared to $14.9 million for the nine months ended September 30, 2023. The increase in cash used in operating activities resulted primarily from the combination of increased net loss and the advance of deposit funds to vendors supporting the ReMEDy2 clinical trial during, the current year period, partially offset by changes in operating assets and liabilities during the current year period.

Financial Results

Research and development (R&D) expenses increased to $5.0 million for the three months ended September 30, 2024, up from $3.3 million for the three months ended September 30, 2023. R&D expenses increased to $12.6 million for the nine months ended September 30, 2024, up from $9.4 million for the nine months ended September 30, 2023. These increases are due primarily to increased costs resulting from the continuation of the ReMEDy2 clinical trial, the expansion of the Company's clinical team and increased manufacturing development activity. These increases were partially offset by decreased costs related to clinical trial work completed in 2023, including the Phase 1C and REDUX trials, and the completion in 2023 of in-use study work performed to address the prior clinical hold on the ReMEDy2 trial. DiaMedica expects R&D expenses to increase moderately relative to recent prior periods as it globally expands the ReMEDy2 trial site activations and participant enrollments continue.

General and administrative (G&A) expenses were $1.9 million for each of the three month periods ended September 30, 2024 and 2023. G&A expenses were $5.7 million for the nine months ended September 30, 2024, down from $6.0 million for the nine months ended September 30, 2023. The decrease for the nine-month comparison resulted from the combination of reductions in the cost of directors and officers liability insurance premiums and decreased legal fees incurred in connection with DiaMedica's lawsuit against PRA Netherlands and was partially offset by increased personnel costs incurred in conjunction with expanding the team and increased non-cash share-based compensation costs. DiaMedica expects G&A expenses to remain steady as compared to recent prior periods.

Other income, net, was $616 thousand and $1.8 million for the three and nine months ended September 30, 2024, respectively, compared to $693 thousand and $1.2 million for the three and nine months ended September 30, 2023, respectively. The nine-month comparison increase was driven by increased interest income recognized during the current year period related to a higher average marketable securities balance compared to the prior year period.

About the Acute Ischemic Stroke Phase 2/3 ReMEDy2 Trial

The ReMEDy2 trial is an adaptive design, randomized, double-blind, placebo-controlled trial studying the use of the Company's product candidate, DM199, to treat acute ischemic stroke patients. The trial is intended to enroll approximately 350 patients at up to 100 sites globally. Patients enrolled in the trial will be treated for three weeks with either DM199 or placebo, beginning within 24 hours of the onset of AIS symptoms, with the final follow-up at 90 days. 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. Participants treated with tissue plasminogen activator (tPA) or tenecteplase (TNK), (thrombolytic agents) intended to dissolve blood clots, are eligible for participation if they continue to experience a persistent neurological deficit after receiving thrombolytic treatment and meet all other trial criteria. DiaMedica believes that the proposed trial has the potential to serve as a pivotal registration study of DM199 in this patient population.

About the Preeclampsia Phase 2 Trial

PE is a serious pregnancy disorder that typically develops after the 20th week of gestation, characterized by high blood pressure and damage to organ systems, often the kidneys and liver. Affecting up to 8% of pregnancies worldwide, preeclampsia can pose significant risks to both the mother and baby, including risk of stroke, placental abruption, progression to eclampsia, premature delivery, and death. This Phase 2 open-label, single center, single-arm, safety and pharmacodynamic, proof-of-concept, investigator-sponsored study of DM199 in treating preeclampsia is being conducted at the Tygerberg Hospital, Cape Town, South Africa (SA), under the direction of Catherine Cluver, MD, PhD, Professor of Maternal/Fetal Medicine, Stellenbosch University, Stellenbosch, SA, in collaboration with DiaMedica. This trial will enroll up to 90 women with preeclampsia and potentially 30 subjects with fetal growth restriction. Dosing commenced in the fourth quarter of 2024. Part 1A top line study results are anticipated in the first half 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.

About DM199

DM199 (rinvecalinase alfa) is a recombinant form of human tissue kallikrein-1 (rhKLK1) in clinical development for acute ischemic stroke and preeclampsia. KLK1 is a serine protease enzyme that plays an important role in the regulation of diverse physiological processes via a molecular mechanism that increases production of nitric oxide, prostacyclin and endothelium-derived hyperpolarizing factors. 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.
