About Hyperoxaluria

Hyperoxaluria is a serious metabolic disorder and is one of the major risk factors for nephrolithiasis, nephrocalcinosis, and oxalate nephropathy that leads to chronic kidney disease. Hyperoxaluria is a direct result of either hyper-absorption of oxalate from the diet (secondary hyperoxaluria) or from overproduction of oxalate due to a hereditary enzyme deficiency in the liver (primary hyperoxaluria). No effective pharmacologic treatment exists for hyperoxaluria.

About ALLN-177

Allena’s lead product, ALLN-177 is an orally administered highly active recombinant oxalate degrading enzyme for the chronic management of hyperoxaluria and kidney stones. ALLN-177 has the potential to degrade both dietary and endogenously produced oxalate in the GI tract and decrease its absorption. This degradation of oxalate may reduce or prevent oxalate deposition as calcium oxalate crystals or stones in the kidneys and urinary tract, as well as other related complications. ALLN-177 is in an ongoing Phase 2 clinical trial in patients with secondary hyperoxaluria.
