Bridging Pharmacokinetic Study Initiated
CALGARY, Alberta, March 14, 2022 (GLOBE NEWSWIRE) -- XORTX Therapeutics Inc. ("XORTX" or the “Company”) (NASDAQ: XRTX | TSXV: XRTX | Frankfurt: ANU), a pharmaceutical therapeutics company focused on developing innovative therapies to treat progressive kidney disease, today announces that it submitted a clinical trial application (CTA) with Health Canada for a XRX-OXY-101 bridging pharmacokinetics study.
XRX-OXY-101 Bridging Pharmacokinetics Study. XRX-OXY-101 has been designed with three important objectives: 1) to determine which of XORTX’s novel formulations results in the best circulating oxypurinol concentrations; 2) the effect of food on the bioavailability of this formulation; and 3) the safety and pharmacokinetics of multiple doses of this selected formulation. Knowledge gained during the conduct of this trial will provide guidance regarding the future oral dosing of oxypurinol formulations in support of the Company’s planned phase 3 registration trial in Autosomal Dominant Polycystic Kidney Disease (“ADPKD”). Additionally, this study will provide data to support future NDA (New Drug Application) marketing submissions to the United States Food and Drug Administration and the European Medicines Agency.
Dr. Allen Davidoff stated, “XORTX is pleased to have made this regulatory filing step to initiate the launch of the XRX-OXY-101 bridging pharmacokinetic study. While only several months in duration, this XRX-OXY-101 study is an important first clinical step in our 505(b)2 clinical and regulatory plan for 2022 and will support the XRx-008 program for ADPKD as well as the planned phase 3 registration trial. This clinical trial initiated in Canada will provide key information to be used for the development of XRx-008 through the US FDA 505(b)2 marketing approval process.”
About Autosomal Dominant Polycystic Kidney Disease (“ADPKD”)
ADPKD is a rare disease that affects more that 10 million individuals worldwide.1,2 ADPKD is typically diagnosed based upon expansion of fluid-filled cysts in the kidneys. Over time, the increasing number and size of cysts can contribute to structural and functional changes to kidneys and is frequently accompanied by chronic pain which is a common problem for patients with ADPKD.3 Expansion of cysts is thought to compress healthy functioning tissue surrounding the cysts and contribute to further loss of kidney function, fibrosis, impaired nutrient exchange and impaired kidney function, accompanied later by end-stage renal disease (ESRD).1 For individuals with progressing ADPKD, treatment recommendations include anti-hypertensive treatment and dietary restrictions.4 New therapies to slow decline of kidney function in ADPKD are needed.
