• VB4-P5 – novel new chemical entity with potential to address significant unmet need in rare and large-market chronic kidney disease •
CALGARY, Alberta, April 13, 2026 (GLOBE NEWSWIRE) -- XORTX Therapeutics Inc. ("XORTX" or the “Company”) (NASDAQ: XRTX | TSXV: XRTX | Frankfurt: ANU), a late-stage clinical pharmaceutical company focused on developing innovative therapies to treat gout and progressive kidney disease, is pleased to announce the closing of the acquisition of the Vectus kidney anti-fibrotic asset (the “Acquisition”). The Company announced that it entered a binding term sheet on October 17, 2025 to acquire a Renal Anti-Fibrotic Therapeutic Program (the “Program”) from Vectus Biosystems Limited, an Australian Securities Exchange listed company (“Vectus”) and provided timing updates on December 31, 2025 and February 4, 2026.
The Program includes a novel new chemical entity, VB4-P5, along with its associated intellectual property, regulatory documentation, and manufacturing data. The Program is currently at the pre-IND (Investigational New Drug) stage of development and targets both rare and prevalent forms of kidney disease — areas with substantial unmet medical need. Assets included with the Acquisition are the patent family specifically related to the VB4-P5 compound and its use to treat kidney fibrosis, as well as the data generated by Vectus from its work on the VB4-P5 small molecule and related assets.
As consideration for the Acquisition, XORTX has issued 154,544 common shares (the “Common Shares”) at a deemed issue price of US
Dr. Allen Davidoff, Chief Executive Officer of XORTX, stated, “We are pleased to have finalized the Acquisition of the VB4-P5 program for kidney disease. This program is directly aligned with our strategic focus on developing innovative therapies to treat individuals with progressive kidney disease and broadens our pipeline with a new technological direction. We believe this novel agent has the potential to be a new treatment for mid-late stage chronic kidney disease, slow kidney disease progression and accompanying fibrosis.”
About Kidney Disease and Fibrosis
Chronic kidney disease (CKD) affects an estimated
Kidney fibrosis is a hallmark of CKD progression. It is characterized by the excessive accumulation of extracellular matrix that follows renal injury. Untreated, it will ultimately lead to renal dysfunction, and high morbidity and mortality3. Rare kidney diseases such as autosomal dominant polycystic kidney disease (ADPKD)4 and lupus nephritis5 also produce kidney fibrosis, contributing to the deterioration of kidney and cardiovascular function in these patients. Current treatments for kidney fibrosis focus primarily on blood pressure control and include dietary interventions. No currently approved therapies specifically target or reverse kidney fibrosis.
About the VB4-P5 Program
Early preclinical data from the VB4-P5 program demonstrate the potential of this potent small molecule to inhibit and possibly reverse kidney fibrosis. Patent protection for VB4-P5 includes composition-of-matter and method-of-use claims across more than 30 global jurisdictions, positioning the program for broad development and commercialization opportunities.
