MINNEAPOLIS--(BUSINESS WIRE)-- DiaMedica Therapeutics Inc. (Nasdaq: DMAC), a clinical-stage biopharmaceutical company focused on developing novel treatments for kidney diseases and neurological disorders, today provided a business update and reported its financial results for the three and nine months ended September 30, 2019.

Clinical Developments

DM199 for the Treatment of Chronic Kidney Disease

Phase Ib Clinical Study in Patients with CKD Completed

DiaMedica has completed its Phase Ib clinical trial of DM199, a recombinant form of the endogenous human tissue kallikrein protein (KLK1), in patients with moderate or severe Chronic Kidney Disease (CKD) caused by Type I or Type II diabetes mellitus. The study was performed to assess the pharmacokinetics (PK) of three dose levels of DM199 (3, 5 and 8 µg/kg), administered in a single subcutaneous dose, as well as the evaluation of safety, tolerability and secondary pharmacodynamic (PD) endpoints.

The Company previously announced positive interim results. PK profiles, at the 3µg/kg dose level, were similar between moderate and severe CKD patients, and consistent with healthy subjects (normal kidney function) tested previously. Therefore, the Company does not believe dosing adjustment is warranted, based on the presence or severity of CKD and a full renal study will likely not be required. Final study results indicated that DM199 was observed to be well tolerated with no dose-limiting tolerability. There were no deaths, no discontinuations due to a treatment-related adverse event (AE), and no treatment-related significant adverse events (SAEs). AEs were minor and consistent with standard treatment(s) in the CKD patient population.

Favorable overall PD results were also observed including short-term improvements in Nitric Oxide (NO), average increase of 35.2%, Prostaglandin E₂ (PGE₂), average increase of 41.2%, estimated glomerular flow rate (eGFR), average increase of 4.08 mL/min/173², and the urinary albumin to creatinine ratio (UACR), average decrease of 18.7%. PD results appeared to be drug related in that greatest improvements occurred at approximately 24 hours after DM199 administration and subsequently declined.

DiaMedica intends to release full study results at an upcoming conference, including a breakout analysis of moderate and severe patients and results by dose level.

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

The U.S. Food and Drug Administration (FDA) has accepted the Company’s Phase II clinical trial protocol for the treatment of CKD caused by rare or significant unmet diseases. This study is designed to investigate the safety, efficacy, PK and PD of DM199. Screening of patients has commenced and the enrollment and dosing is expected in the near term.

The Phase II trial named REDUX, latin for restore, is a multi-center, open-label investigation of approximately 60 participants with CKD, who are being enrolled in two cohorts (30 per cohort). The study is being conducted in the United States at up to 10 sites and will be focused on participants with CKD: Cohort I is focused on non-diabetic, hypertensive African Americans with Stage II or III CKD. African Americans are at greater risk for CKD than Caucasians, and those 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 focused on participants with IgA Nephropathy (IgAN). The study will evaluate two dose levels of DM199 within each cohort. Study participants 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 eGFR and albuminuria, as measured by the UACR.

“We are pleased with the results from our CKD Phase Ib study and our ability to now commence Phase II studies,” commented Dr. Harry Alcorn, DiaMedica’s Chief Medical Officer. “We look forward to our Phase II study building on our successful Phase Ib data and we have engaged a number of study sites that have the patient populations and experience in obtaining high quality data to better understand the potential of DM199 in benefitting individuals suffering with CKD, whose current treatment options are very limited.”

DM199 for the Treatment of Acute Ischemic Stroke

DM199 Acute Ischemic Stroke Phase II “REMEDY” Trial Update – Enrollment Completed

DiaMedica has recently completed enrollment in the REMEDY trial, the Company’s Phase II study assessing the safety, tolerability and markers of therapeutic efficacy of DM199 in participants suffering from Acute Ischemic Stroke (AIS). Final enrollment was 92 participants. The markers of therapeutic efficacy will include multiple plasma-based biomarkers (e.g. C-reactive protein), the Modified Rankin Scale, National Institutes of Health Stroke Scale and the Barthel Index. These markers are assessed at multiple points throughout the study, including 90 days post-stroke.

Organizational Update

Dr. Sydney A. Gilman has joined DiaMedica as its Vice President of Regulatory Affairs. Dr. Gilman has over 30 years of pharmaceutical industry experience holding senior positions including at Elan Pharmaceuticals and Amylin Pharmaceuticals. Dr. Gilman also spent six years as a CMC reviewer with the FDA’s Center for Drug Evaluation and Research group. In his most recent role as founder and Senior Regulatory Consultant of Trident Rx Consulting, Dr. Gilman has been involved in the development and implementation of strategic plans for drug development and regulatory strategy for new drugs and biologics. In addition he has lead a variety of global regulatory submissions, including INDs, NDAs, BLAs, MAAs, global CTAs, 510Ks, PMAs, orphan and Fast Track submissions, and clinical study reports.

“We continue to make great progress with our clinical programs with the commencement of our Phase II CKD studies and the completion of enrollment in our REMEDY Phase II study, and I wish to thank our clinical team for their skill and dedication,” stated Rick Pauls, DiaMedica’s President and CEO. “I would also like to welcome Dr. Gilman, who is a strong addition at this critical time. His proven track record in leading regulatory affairs is instrumental as we transition DM199 into Phase II and Phase III clinical trials and work to improve the lives of CKD and AIS patients.”

Financial Results

Research and development (R&D) expenses increased to $1.6 million for the three months ended September 30, 2019, up from $1.2 million for the three months ended September 30, 2018, an increase of $0.4 million. R&D expenses increased to $6.1 million for the nine months ended September 30, 2019, compared to $3.1 million for the nine months ended September 30, 2018, an increase of $3.0 million. The increase for the nine months ended September 30, 2019 was due to costs of approximately $1.4 million incurred for a new production run of the DM199 drug substance, as well as costs incurred in conjunction with the Phase Ib and Phase II clinical studies in CKD patients and related non-clinical testing. Increased personnel and non-cash share-based compensation costs also contributed to the increase. The increase for the three months ended September 30, 2019 was due to costs incurred in conjunction with the Phase Ib and Phase II CKD studies and non-cash share-based compensation costs, partially offset by a decline in costs incurred in conjunction with the REMEDY Phase II stroke study.

General and administrative (G&A) expenses were $1.0 million for the three months ended September 30, 2019, compared to $777,000 for the three months ended September 30, 2018. G&A expenses increased to $2.7 million for the nine months ended September 30, 2019, up from $2.1 million for the nine months ended September 30, 2018. These increases were primarily due to costs associated with our status as a Nasdaq-listed U.S. public reporting company, which commenced in December 2018, including increased professional services, compliance and non-cash share-based compensation costs. Increased personnel costs also contributed to the increase on a year to date basis.

Total other income increased to $225,000 for the three months ended September 30, 2019, up from $157,000 for the prior year period. Total other income decreased to $683,000 for the nine months ended September 30, 2019, compared to $946,000 for the nine months ended September 30, 2018. The year-to-date decrease is primarily related to the initial recognition of R&D incentives from the Australian Government paid for qualifying research work performed by DiaMedica Australia Pty Ltd. during the nine months ended September 30, 2018. The increase in the quarterly comparison relates to increased study costs, compared to the prior year period, driving an increase in the eligible R&D incentive. The year-to-date decrease was partially offset by, and the current quarter increase was augmented by, increased interest income earned on marketable securities during the three and nine months ended September 30, 2019.

Balance Sheet and Cash Flow

The Company had cash and cash equivalents of $4.7 million, marketable securities of $5.0 million, current liabilities of $1.3 million and working capital of $9.6 million as of September 30, 2019, compared to $16.8 million in cash and cash equivalents, $1.3 million in current liabilities and $16.7 million in working capital as of December 31, 2018. The decreases in combined cash and cash equivalents and marketable securities and in working capital are due primarily to the Company’s operating loss incurred for the nine months ended September 30, 2019.

Net cash used in operating activities was $7.2 million for the nine months ended September 30, 2019, compared to $3.8 million for the nine months ended September 30, 2018. The net cash used in each of these periods primarily reflects the net loss for these periods, and was partially offset by non-cash charges for stock-based compensation and 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.
