Arch Biopartners Engages Private Laboratory to Accelerate IL-32 Chronic Kidney Disease Program
TORONTO, July 17, 2026 (GLOBE NEWSWIRE) — Arch Biopartners Inc. (TSX Venture: ARCH and OTCQB: ACHFF) today announced that it has engaged a U.S.-based laboratory specializing in bioengineering to accelerate the Company’s pre-IND IL-32 chronic kidney disease (“CKD”) program.
The U.S.-based lab was selected for its core competencies in the areas required to support the IL-32 program. It will perform studies on behalf of Arch to generate proprietary data and support the Company’s patent portfolio covering its IL-32 drug candidates and related method-of-use claims. These studies represent the next stage of drug development following the identification of IL-32 as a potential therapeutic target in diabetic kidney disease.
“This research contract is an important step in advancing the Company’s IL-32 CKD drug development program,” said Richard Muruve, Chief Executive Officer of Arch Biopartners. “This work will help move the program forward while building a proprietary body of data to support the Company’s development and partnering strategy.”
Arch’s CKD program is focused on diabetic kidney disease (“DKD”), a leading cause of kidney failure in the United States.1 The program is supported by findings from human kidney tissue and disease models linking IL-32 to lipid droplet biology, inflammation and tubular injury in DKD.
Peer-reviewed findings published in Inflammation Research in February 2026 provided further evidence of IL-32’s association with metabolic stress, chronic inflammation and kidney injury in DKD. These findings support the Company’s rationale for developing therapies designed to target IL-32.
