Clinical Developments

DM199 for the Treatment of Acute Ischemic Stroke

DM199 Acute Ischemic Stroke Phase II “ReMEDy” Trial – Positive Top-Line Data

DiaMedica today announced positive top-line results from its ReMEDy trial, a Phase II study assessing the safety, tolerability and therapeutic potential of DM199 in participants suffering from AIS. Final enrollment was 92 participants. The markers of therapeutic efficacy included the National Institutes of Health Stroke Scale, Modified Rankin Scale and the Barthel Index and multiple plasma-based biomarkers (e.g. C-reactive protein). These markers were assessed at multiple points throughout the study, including 90 days post-stroke.

DM199 met primary safety and tolerability endpoints and no DM199-related serious adverse events were noted in the study. According to top-line phase II results, there was also a demonstrated therapeutic effect in participants who received tissue plasminogen activator (tPA) prior to enrollment, but not in participants receiving mechanical thrombectomy.

"We are very excited about the positive top-line results which continue to demonstrate the excellent safety profile of DM199 and efficacy signals which are consistent with the approval study for Kailikang®, the urine-derived form of KLK1 which has been used to successfully treat stroke patients in China for years,” stated Rick Pauls, DiaMedica’s President and CEO. “These results strengthen our belief that DM199 can be a valuable treatment option for stroke victims, improving outcomes while providing a significantly longer, up to 24 hours, after onset of the stroke. We look forward to discussing a path to commercialization with the FDA.”

DM199 for the Treatment of Chronic Kidney Disease

Phase II Clinical Study in CKD Caused by IgA Nephropathy and in African Americans with Hypertension – Enrollment Continues

The Phase II REDUX (latin for restore) trial is a multi-center, open-label investigation of approximately 60 participants with chronic kidney disease (CKD), who are being enrolled in two cohorts (30 per cohort). The study is ongoing in the United States at 12 sites and targets participants with CKD: Cohort I is enrolling non-diabetic, hypertensive African Americans with Stage II or III CKD, a group which is at greater risk for CKD than Caucasians. African Americans who have the APOL1 gene mutation are at an even higher risk. The study is designed to capture the APOL1 gene mutation as an exploratory biomarker in this cohort. Cohort II is enrolling participants with IgA Nephropathy (IgAN). The overall study evaluates two dose levels of DM199. Study participants in each cohort will receive DM199 by subcutaneous injection twice weekly for 95 days. The primary study endpoints include safety, tolerability, blood pressure, proteinuria and kidney function, which will be evaluated by changes from baseline in estimated glomerular filtration rate (eGFR) and albuminuria, as measured by the urinary albumin to creatinine ratio (UACR).

Due to actions implemented to combat the novel strain of the coronavirus (COVID-19) pandemic, the Company is experiencing slower than expected enrollment in the REDUX clinical study as activities are reduced or suspended at the clinical study sites as they address staff and patient safety concerns.The Company currently expects a delay in the timing of costs incurred as a result of the COVID-19 pandemic, but not a significant overall increase. The Company will continue to assess the effect of the pandemic on its REDUX trial by monitoring the spread of the COVID-19 virus and the actions implemented to combat the virus.

“Our highest priority right now is to protect the safety of subjects and clinical staff participating in the REDUX trial, and we believe that we have accomplished that” commented Dr. Harry Alcorn, DiaMedica’s Chief Medical Officer. “While enrollment has significantly slowed, we believe that the measures taken will allow our study to resume more normal rates of enrollment as COVID-19 related restrictions are eased.”

Public Offering of Common Shares

On February 13, 2020, the Company issued and sold an aggregate of 2,125,000 common shares in a public, underwritten offering at a public offering price of $4.00 per share. As a result of the offering, the Company received gross proceeds of $8.5 million and net proceeds of $7.7 million, after deducting the underwriting discount and offering expenses.

Financial Results

Research and development (R&D) expenses were $1.4 million for the three months ended March 31, 2020, compared with $2.6 million for the three months ended March 31, 2019, a decrease of $1.2 million. The decrease was due to costs incurred during the first quarter of 2019 which did not reoccur during the first quarter of 2020, primarily the costs for a production run of the DM199 drug substance and the Phase Ib study in CKD patients. Declining costs for the ReMEDy study in the current year period also contributed to the decrease. These decreases were partially offset by costs incurred for the REDUX study, which began enrollment in December 2019, and increased non-cash share-based compensation costs.

General and administrative (G&A) expenses were $1.0 million for the three months ended March 31, 2020, up from $814,000 for the three months ended March 31, 2019. The increase in G&A expenses resulted primarily from increased non-cash share-based compensation costs.

Total other (income) expense, net, for the three months ended March 31, 2020 was a net expense of $12,000, compared with net income of $178,000 for the three months ended March 31, 2019. The change was primarily caused by the foreign currency transaction losses associated with funds held in non-functional currency (US dollar) accounts, principally Australian dollars. A decrease in R&D incentives, associated with decreased ReMEDy costs and reductions in interest income earned on marketable securities during the three months ended March 31, 2020, also contribute to this change.

Balance Sheet and Cash Flow

The Company had cash, cash equivalents and marketable securities of $12.6 million, current liabilities of $0.9 million and working capital of $13.2 million as of March 31, 2020, compared to $7.9 million in cash, cash equivalents and marketable securities, $1.3 million in current liabilities and $7.5 million in working capital as of December 31, 2019. The increases in the Company’s combined cash, cash equivalents and marketable securities and in its working capital are due primarily to the February 2020 public offering of common shares.

Net cash used in operating activities was $3.0 million for the three months ended March 31, 2020, compared to $3.1 million for the three months ended March 31, 2019. The net cash used in each of these periods primarily reflects the net loss for these periods, offset by non-cash charges for stock-based compensation and adjusted for the net effects of changes in operating assets and liabilities.

About DM199

DM199 is a recombinant (synthetic) form of the human serine protease, KLK1. The KLK1 protein plays an important role in the regulation of diverse physiological processes including blood flow, inflammation, fibrosis, oxidative stress and neurogenesis via a molecular mechanism that increases production of nitric oxide and prostaglandin. KLK1 deficiency may play a role in multiple vascular and fibrotic diseases such as chronic kidney disease, retinopathy, stroke, vascular dementia, and resistant hypertension where current treatment options are limited or ineffective. DiaMedica is the first company to have developed a recombinant form of the KLK1 protein. The KLK1 protein, produced from porcine pancreas and human urine, has been used to treat patients in Japan, China and Korea for decades. DM199 is currently being studied in patients with chronic kidney disease and patients with acute ischemic stroke.
