Allena Pharmaceuticals Presents Preclinical Data Demonstrating Normalized Urine Uric Acid Excretion and Plasma Urate Reduction Following Treatment with ALLN-346
Data Presented in Poster Session at 2018 ACR/ARHP Annual Meeting
NEWTON, Mass., Oct. 22, 2018 (GLOBE NEWSWIRE) -- Allena Pharmaceuticals, Inc. (NASDAQ:ALNA), a late-stage biopharmaceutical company dedicated to developing and commercializing first-in-class, oral enzyme therapeutics to treat patients with rare and severe metabolic and kidney disorders, today announced preclinical proof-of-concept data for ALLN-346, its lead product candidate for hyperuricemia and gout in the setting of advanced chronic kidney disease (CKD). The data were presented in a poster session on Saturday, October 20, 2018 at the 2018 American College of Rheumatology (ACR/ARHP) Annual Meeting in Chicago, IL.
The poster presentation includes data demonstrating urate reduction in a urate oxidase knock-out mouse model, an animal model of severe hyperuricemia with kidney damage due to urate crystal deposition. After one week of treatment, mice treated with ALLN-346 achieved a substantial reduction in urate burden on the kidney, as evidenced by normalization in urine uric acid and a significant reduction in plasma urate.
“We are excited to report preclinical proof-of-concept for ALLN-346, our enzyme designed to degrade urate in the gastrointestinal tract, and thereby limit the burden on the kidneys over time,” said Alexey Margolin, Ph.D., Chief Executive Officer of Allena Pharmaceuticals. “Based on these data, we are working expeditiously to finish our preclinical program for ALLN-346 and scale our manufacturing processes for clinical studies. We expect to file an investigational new drug application with the U.S. Food and Drug Administration in 2019, as we continue to execute on our mission of advancing a product pipeline to address severe metabolic and kidney-related disorders.”
Hyperuricemia results from the overproduction and/or insufficient excretion of uric acid, and is a significant predisposing condition for gout. Increased uric acid excretion in the urine and hyperuricemia are also associated with kidney stone formation and kidney damage. Patients with renal impairment who have hyperuricemia and gout are often not optimally managed due to limitations of available therapies, including decreased tolerability, dose restrictions, drug-drug interactions, and contraindications. According to a recent study, there are approximately 375,000 patients with hyperuricemia and CKD on urate lowering therapy who have uncontrolled gout.1
“Patients with moderate to severe CKD who experience hyperuricemia and gout are often not optimally managed with existing therapies, including xanthine oxidase inhibitors and uricosurics, due to poor tolerability, and dose restriction with reduced efficacy,” said Robert Terkeltaub, M.D., Professor of Medicine at University of California San Diego and co-investigator for the study. “These preclinical results demonstrate that the underlying physiology of hyperuricemia and the extrarenal pathway for uric acid elimination correspond to the mechanism of ALLN-346, an oral enzyme designed to degrade urate in the gastrointestinal tract. As a result, they suggest that ALLN-346 may provide a new option for reducing the burden of filtered and excreted uric acid on the kidney. We look forward to evaluating the potential of this treatment in human clinical trials.”
Hyperuricemia, or elevated levels of uric acid in the blood, results from overproduction or insufficient excretion of urate, or often a combination of the two. Hyperuricemia is associated with gout, a kind of arthritis caused by excess uric acid in the blood that leads to the formation of hard crystals in the joints. Hyperuricemia can also lead to increased uric acid excretion in the urine and subsequently to kidney stone formation and kidney damage also known as urate nephropathy. In addition, hyperuricemia has been linked to hypertension, CKD, glucose intolerance, dyslipidemia, insulin resistance and obesity.
ALLN-346 is an orally administered, novel, engineered urate oxidase that has been optimized for stability in the gastrointestinal (GI) tract and high production yield. Allena has designed ALLN-346 to degrade urate in the GI tract and in turn, reduce the urate burden on the kidney and lower the risk of urate-related complications. ALLN-346 is targeted to lower serum uric acid in patients with CKD, whose renal function is decreased and who have diminished capacity for urinary excretion of uric acid.
