MINNEAPOLIS / May 08, 2024 / Business Wire / DiaMedica Therapeutics Inc. (Nasdaq: DMAC), a clinical-stage biopharmaceutical company focused on developing novel treatments for neurological disorders and cardio-renal disease, today provided a business update and financial results for the quarter ended March 31, 2024. Management will host a conference call Thursday, May 9, 2024 at 8:00 AM Eastern Time / 7:00 AM Central Time to discuss its business update and first quarter 2024 financial results.

ReMEDy2 Phase 2/3 AIS Clinical Developments

DiaMedica, as recently announced, enrolled its first participant in the continuation of its ReMEDy2 trial of DM199 (rinvecalinase alfa) in participants with acute ischemic stroke (AIS). The first clinical sites were opened in December 2023 and as of the date of this press release, eight sites have now been opened. The majority of the U.S. sites are expected to be activated by the end of the third quarter of 2024.

Progress is also being made outside of the United States. With the support of the Canadian Stroke Consortium, the required Senior Medical Officer, who will serve as the national physician investigator for Canada, has been engaged and six quality sites have been identified for inclusion in the trial. DiaMedica currently expects to submit its regulatory filings to Health Canada this month and expects a response by the end of June. The activation of study sites in Canada is expected to begin in the fourth quarter of 2024. The Australian Stroke Trials Network has completed its endorsement of DiaMedica’s protocol and DiaMedica is currently selecting study sites. The Company plans to work with many of the same highly-engaged centers it worked with in the ReMEDy1 trial. Australian site activation remains on track to commence before the end of 2024.

The Company currently believes that, barring any unforeseen circumstances, full enrollment for the 144 patients for the interim analysis will be completed in the first quarter of 2025. For more information about the ReMEDy2 AIS Phase 2/3 clinical trial, please visit (www.remedytrial.com).

"We are diligently working to involve and mobilize top-tier stroke centers, laying a solid groundwork for patient participation," stated Dr. Lorianne Masuoka, DiaMedica’s Chief Medical Officer. "The enthusiasm from premier research sites is uplifting, and we remain dedicated to bringing DM199 to stroke patients."

Balance Sheet and Cash Flow

DiaMedica reported total cash, cash equivalents and investments of $46.5 million, current liabilities of $2.6 million and working capital of $44.9 million as of March 31, 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 cash, cash equivalents and investments and in working capital were due to a combination of net cash used to fund operations, including the advance of deposit funds to vendors supporting the ReMEDy2 trial in the three months ended March 31, 2024.

Net cash used in operating activities for the three months ended March 31, 2024 was $6.7 million compared to $5.1 million for the year three months ended March 31, 2023. The increase in cash used in operating activities was driven primarily by the advance of deposit funds to vendors supporting the ReMEDy2 trial in the current year period.

Financial Results

Research and development (R&D) expenses increased to $3.7 million for the three months ended March 31, 2024, compared to $3.6 million for the three months ended March 31, 2023. This increase was due to increased costs related to the continuation of the ReMEDy2 trial, and was partially offset by cost reductions related to clinical trial work completed in 2023, namely the Company’s Phase 1C and REDUX trials, and the completion in 2023 of in-use study work performed to address the former clinical hold on the ReMEDy2 trial. DiaMedica expects R&D expenses to increase moderately relative to recent prior periods as the global expansion of the ReMEDy2 trial proceeds and site activations and participant enrollments continue. The Company expects these anticipated increases will be moderated by the clinical trial work and in-use studies completed in 2023.

General and administrative (G&A) expenses increased $0.2 million to $2.1 million for the three months ended March 31, 2024, up from $1.9 million for the three months ended March 31, 2023. This increase was primarily driven by increased personnel costs incurred in conjunction with the expansion of DiaMedica’s team, partially offset by a reduction in the cost of directors and officers liability insurance premiums. DiaMedica expects G&A expenses to remain steady as compared to prior periods.

Other income, net, was $597 thousand for the three months ended March 31, 2024 compared to $256 thousand for the three months ended March 31, 2023. This increase was driven by increased interest income recognized during the three months ended March 31, 2024 related to increased marketable securities balances during the current year period as compared to the same prior year period.

About 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 in the United States with planned global expansion. 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 treated with tissue plasminogen activator (tPA) and/or mechanical thrombectomy. DiaMedica believes that the proposed trial has the potential to serve as a pivotal registration study of DM199 in this patient population.

About DM199

DM199 is a recombinant (synthetic) form of human tissue kallikrein-1 (rKLK1; rinvecalinase alpha). rKLK1 is identical to naturally produced KLK1, 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 and prostacyclin. In the case of ischemic stroke, the administration of 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 inhibit of apoptosis (neuronal cell death) while also facilitating neuronal remodeling through the promotion of angiogenesis. KLK1 deficiency may play a role in multiple vascular and fibrotic diseases such as stroke, chronic kidney disease, retinopathy, vascular dementia, and resistant hypertension where current treatment options are limited or ineffective. DiaMedica is the first company to have developed and clinically studied rKLK1. Non-recombinant, tissue extracted KLK1 protein, produced from the pancreas of pigs and human urine, has been approved for decades outside the U.S. and Europe for patients in Japan, China and South Korea with a variety of ischemic conditions such as AIS, chronic renal disease, retinopathy and hypertension. DM199 is currently being studied in patients with AIS. In September 2021, the FDA granted Fast Track Designation to DM199 for the treatment of AIS.
