XORTX Initiates Dosing of Human Subjects in the XRX-OXY-101 Clinical Trial
Bridging Pharmacokinetics Study Part 1 Recruitment Completed for XRx-008 Program for Autosomal Dominant Polycystic Kidney Disease
CALGARY, Alberta, May 03, 2022 (GLOBE NEWSWIRE) -- XORTX Therapeutics Inc. ("XORTX" or the “Company”) (NASDAQ: XRTX | TSXV: XRTX | Frankfurt: ANU), a pharmaceutical company focused on developing innovative therapies to treat progressive kidney disease, is pleased to announce that dosing of human subjects has been initiated in the XRX-OXY-101 bridging pharmacokinetics study (“PK Study”).
Successful recruitment for part 1 of this 3-part clinical trial has been completed with 32 subjects receiving study drug. Following administration of the first dose of drug, blood sampling and bioanalytical evaluation will be conducted to characterize the pharmacokinetics and bioavailability of the XRx-008 program’s novel proprietary formulations of oxypurinol for future clinical trials development. Additionally, this PK Study will provide fundamental information for the 505(b)2 filing of the XRx-008 program.
XORTX’s current conducting our clinical trial - XRX-OXY-101 - a “bridging pharmacokinetics” study. Part 1 of the study involves dosing under fasted conditions. Part 2 measures the effect of food on pharmacokinetics (PK) and Part 3 is a multiple dose PK evaluation. Safety evaluation is also an important aspect of the XRX-OXY-101 clinical trial. The study is designed to permit XORTX to characterize the safety and relative bioavailability of the XRx-008 program formulations. Knowledge gained during the conduct of this trial will provide critical guidance regarding the oral dose for our planned registration trial in 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.1 For individuals with progressing ADPKD, treatment recommendations include anti-hypertensive treatment, dietary restrictions, and, for a limited percentage of suitable patients, pharmacotherapy.4 New, more broadly applicable therapies to effectively slow decline of kidney function in ADPKD are needed.
