Allena Pharmaceuticals Completes Animal Proof-of-Concept Study for ALLN-346, Lead Product Candidate for Hyperuricemia in the Setting of Advanced Chronic Kidney Disease
-- ALLN-346, a Novel, Engineered, Urate Oxidase, Demonstrates Robust Reduction of
-- Data Supports Advancement of ALLN-346 as Allena’s Next Product Candidate for the Treatment of Metabolic and Kidney-Related Disorders –
ALLN-346 is an orally administered, novel urate oxidase that has been optimized for stability in the gastrointestinal (GI) tract. This proprietary enzyme was designed by Allena 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, who have decreased renal function and diminished capacity for urinary excretion of uric acid.
ALLN-346 has demonstrated a robust reduction in both plasma and urine uric acid levels in an established urate oxidase knock-out mouse model, a severe animal model of hyperuricemia with advanced CKD and kidney damage due to urate crystal deposition. Allena expects to present detailed preclinical data for ALLN-346 at a scientific conference in the second half of 2018. Based on the results of this study, Allena is scaling its manufacturing processes and production yield to support customary toxicology and additional preclinical studies and, consistent with prior guidance, expects to file an IND with the
“At Allena, we are employing a proprietary technological approach that allows for the design and formulation of oral non-absorbed, stabilized enzymes that degrade a specific metabolite within the GI tract,” said
Hyperuricemia and gout patients with renal impairment are not optimally managed with existing therapies due to safety concerns, including decreased tolerability to multiple drugs used to treat gout, dose restrictions, drug-drug interactions, contraindications and increased risk for long-term morbidity and mortality. An estimated 375,000 patients in
“As new data continue to emerge, the limitations associated with current agents used to treat hyperuricemia in gout patients with CKD highlight a major unmet need for new targets and therapeutic approaches,” said Dr.
About Hyperuricemia and Gout
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. Humans lack urate oxidase, an enzyme that degrades uric acid in a wide range of other organisms, including animals, plants, bacteria and fungi. Hyperuricemia can be a predisposing condition for gouty flares, arthritis, kidney stones, and kidney damage, which is also known as urate nephropathy. Hyperuricemia is also intricately linked to various metabolic disorders, including hypertension, CKD, glucose intolerance, dyslipidemia, insulin resistance and obesity. It may also be an independent risk factor for cardiovascular disease.
Gout is a form of inflammatory arthritis caused by excess body uric acid burden. When uric acid levels are too high, hard crystals may form in the joints, causing attacks (flares) of sudden burning pain, stiffness, and swelling. These attacks can be recurrent unless gout is treated. Over time, chronic arthritis can develop, which can damage joints, tendons, and other tissues.
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.
This release contains “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995, including statements regarding Allena’s development and regulatory plans for ALLN-346, including the timing and outcome of additional preclinical studies and any future clinical trials, the timing of filing an IND for this product candidate, as well as statements concerning the development program for Allena’s lead product candidate, ALLN-177. Any forward- looking statements in this press release are based on management’s current expectations of future events and are subject to a number of risks and uncertainties that could cause actual results to differ materially and adversely from those set forth in or implied by such forward-looking statements. These risks and uncertainties include, but are not limited to: the risk that results of earlier studies of Allena’s product candidates may not be predictive of future clinical trial results, and planned studies may not establish an adequate safety or efficacy profile for such product candidate that support regulatory approval; risks associated with the fact that Allena has not yet finalized the design of its pivotal Phase 3 clinical program for ALLN-177; risks associated with obtaining, maintaining and protecting intellectual property; risks associated with Allena’s ability to enforce its patents against infringers and defend its patent portfolio against challenges from third parties; the risk of competition from other companies developing products for similar uses; risk associated with Allena’s ability to manage operating expenses and/or obtain additional funding to support its business activities; and risks associated with Allena’s dependence on third parties. For a discussion of other risks and uncertainties, and other important factors, any of which could cause Allena’s actual results to differ from those contained in the forward-looking statements, see the section entitled “Risk Factors” in Item 1A of Part II of Allena’s Quarterly Report on Form 10-Q for the quarter ended
