DiaMedica Announces FDA Clearance of IND Application To Study DM199 in Patients with Chronic Kidney Disease
MINNEAPOLIS, Jan. 03, 2019 (GLOBE NEWSWIRE) -- DiaMedica Therapeutics Inc. (“DiaMedica”) (NASDAQ:DMAC) (TSX-V:DMA) announced today that the U.S. Food and Drug Administration ("FDA") has accepted DiaMedica’s Investigational New Drug application ("IND") for the initiation of a Phase Ib clinical trial of DM199 in patients with moderate or severe Chronic Kidney Disease (“CKD”) caused by Type I or Type II diabetes. The multi-site clinical study will enroll 32 subjects to evaluate DM199 safety, tolerability and drug levels (pharmacokinetics) in this specific population. The study will enroll subjects over a 12 day period and will also include other end points that include renal biomarkers.
The results from this Phase Ib study will assist DiaMedica in the design of upcoming Phase II studies in patients suffering from rare diseases and CKD. The DM199 drug levels from this Phase Ib study will also help determine the optimal dose levels for testing in the Phase II studies.
Dr. Harry Alcorn, DiaMedica’s Chief Medical Officer commented, “The FDA has accepted our IND and protocol for the Phase Ib study and we are excited to initiate our first clinical trial with DM199 in patients with CKD caused by T1D or T2D in the United States.” Dr Alcorn further commented “We believe that DM199 has the potential to significantly improve the lives of patients with mild, moderate or severe CKD and we look forward to performing the clinical research required to evaluate DM199’s potential benefits.”
We are very pleased with the clinical team’s progress, both with finalizing the IND with the FDA and the selection of key clinical trial sites that have the knowledge and experience in conducting these types of studies in patients with kidney disease,” commented Rick Pauls, DiaMedica’s Chief Executive Officer. “We anticipate completing the Phase Ib study by mid-2019 and the Phase II study in Q4 2019 or Q1 2020.”
CKD is a widespread health problem that generates significant economic burden throughout the world. According to the National Kidney Foundation, 30 million Americans and 120 million Chinese suffer from this debilitating and potentially life-threatening condition. CKD is a progressive condition causing the kidneys to lose function over time, increasing the risk of premature death, cardiovascular events, and hospitalization. End stage renal disease (“ESRD”) is the final stage of CKD and requires ongoing dialysis or a kidney transplant to survive, but many patients suffer serious health consequences or die from CKD prior to developing ESRD. Currently, there is no cure for CKD and treatment focuses on managing the symptoms of the disease. Blood pressure medications, such as angiotensin converting enzyme inhibitors (“ACEi”) or angiotensin receptor blockers (“ARB”), are often prescribed to control hypertension, and hopefully, slow the progression of CKD. Nevertheless, according to the National Kidney Foundation, many patients continue to show declining kidney function. DiaMedica believes DM199 offers a potentially novel approach for the treatment of CKD by managing KLK1 levels, as this protein plays a vital role in normal kidney function. Since patients with moderate to severe CKD often excrete abnormally low levels of KLK1 in their urine, DiaMedica believes that DM199 may prevent or reduce further kidney damage by replenishing endogenous KLK1 and restoring the protective kallikrein-kinin system to regulate the production and release of nitric oxide and prostacyclin.
DM199 is a recombinant form of human tissue kallikrein-1 (“KLK1”). KLK1 is an endogenous serine protease (protein) produced in the kidneys, pancreas and salivary glands, which plays a critical role in the regulation of local blood flow and vasodilation (the widening of blood vessels which decreases blood pressure) in the body, as well as an important role in managing inflammation and oxidative stress (an imbalance between potentially damaging reactive oxygen species, or free radicals, and antioxidants in your body). 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 (pig) pancreas and human urine, has been used to treat patients in Japan, China and Korea. DM199 is currently being studied in a Phase II trial in patients with acute ischemic stroke.
