Allena Pharmaceuticals Announces Initial Data from Phase 1 Trial of ALLN-346
-- Single-Ascending Doses of ALLN-346 Oral Enzyme Well-Tolerated --
-- Non-Absorption of ALLN-346 Demonstrated --
-- Advancing to Phase 1b Multiple-Ascending Dose Study and Phase 2 Proof-of-Concept Trial; Initial Data from Both Studies Expected in Second Half of 2021 --
The double-blind, placebo-controlled, single-ascending dose study enrolled 24 healthy volunteers. Groups of eight study participants were randomized 3:1 to ALLN-346 or matching placebo in three sequential cohorts dosed orally with three, six, or 12 capsules in one day. Each capsule of ALLN-346 contained a target dose of 90 mg of enzyme, equivalent to 2,250 units. ALLN-346 was well-tolerated with no clinically significant safety signals and no dose-limiting toxicities observed in any cohort up to the highest administered dose. In addition, assay of serum samples by ELISA immunoassay demonstrated that ALLN-346 was not absorbed systemically, supporting that its mechanism of action appears to be restricted to the GI tract.
“We are very encouraged by the preliminary safety and tolerability data collected for ALLN-346 in healthy volunteers,” said

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.
CKD patients with 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 published study, there are approximately 375,000 patients in the United States with hyperuricemia and CKD on urate lowering therapy who have uncontrolled gout.1

ALLN-346 is an investigational, orally administered, novel, engineered urate oxidase that has been optimized for stability in the 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.
