- Phase II Clinical Study in ADPKD Planned
CALGARY, Alberta, Sept. 10, 2018 (GLOBE NEWSWIRE) -- XORTX Therapeutics Inc. ("XORTX" or the “Company”) (CSE:XRX; OTCQB:XRTXF), a biopharmaceutical company focused on developing innovative therapies to treat progressive kidney disease, is pleased to announce that the Company along with its collaborative partner, Cato Clinical Research, has submitted documents to the US Food and Drug Administration (FDA) to receive Orphan Drug Designation (ODD) status for XORTX’s XRx-008 (a proprietary formulation of Oxypurinol) program for the treatment of autosomal dominant polycystic kidney disease ( ADPKD).
Dr. Allen Davidoff, XORTX’s CEO commented, “Orphan Drug Designation status is an important milestone for the XRx-008 program for ADPKD. ODD recognition by the FDA provides a variety of tax incentives, enhanced patent protection and marketing rights as well as, clinical research subsidies. The benefit to this XORTX program and patients with ADPKD is that XRx-008 can be advanced more quickly. That in turn permits XORTX to efficiently establish the merit of this program and create future value for shareholders. Our hope is that the planned phase II clinical trial for this program will demonstrate the ability of this therapy to slow or stop the deleterious effects of uncontrolled uric acid levels.”
XORTX is focused on advancing XRx-008 through phase II clinical trials for the treatment of ADPKD. Strong scientific and clinical evidence suggests that in this patient population, uric acid concentration can deleteriously affect progression of kidney disease. Managing purine and uric acid levels in patients shows promise as a therapy to slow the rate at which filtering capacity in kidneys decreases. Currently there are few FDA approved therapeutic options to treat progressive kidney disease (PKD) in patients with polycystic kidney disease.
Dr. Richard Johnson, a respected Thought Leader and Scientific and Clinical Advisory Board member for XORTX stated, “ADPKD is one of the most important causes of kidney disease in the world. Serum uric acid is commonly elevated in this disease and there is increasing evidence that it may contribute to the progression of kidney disease. I am delighted to see XORTX take a major step in announcing its desire to perform a clinical trial on the effect of uric acid-lowering on ADPKD. New treatments are badly needed and the potential for this treatment to have a significant beneficial effect is high.”
Orphan Drug programs in the United States – programs for the treatment of rare disease – were passed into law in 1983 to facilitate development of orphan drugs – drugs for rare diseases such as ADPKD, Huntington’s disease, ALS and muscular dystrophy. These rare diseases typically have fewer than 200,000 patients living in the US and due to small patient numbers would not be considered economically feasible without government programs to support their economic viability. ODD does not indicate that the therapeutic is either safe and effective or legal to manufacture and market in the United States. That process is handled through other offices in the FDA, however an ODD designation would qualify XORTX for a number of benefits from the US federal government, such as reduced taxes and grants to fund future clinical trial work – a potentially substantial non-dilutive funding benefit to shareholders. Similar programs for rare diseases exist in European Union, Japan and other countries. Orphan drugs generally follow the same regulatory development path as any other pharmaceutical product, in which testing focuses on pharmacokinetics and pharmacodynamics, dosing, stability, safety and efficacy, however, some statistical burdens are lessened in an effort to maintain development momentum. As a result of world wide support for the development of therapeutic solutions to disease, orphan programs are some of the most successful, time and cost effective programs to develop.
