2° Hyperoxaluria

Secondary hyperoxaluria is a disease with significant unmet medical need. Patients demonstrate wide ranging severity, from manageable symptoms to severe and chronic complications.

There are two types of Secondary (2°) Hyperoxaluria : Idiopathic Hyperoxaluria (IH) and Enteric Hyperoxaluria (EH) 1, 2, 3 .

IH is the most common type, and mostly observed in individuals with calcium oxalate kidney stones1, 4, 5.

EH is partly caused by an underlying gastrointestinal complication associated with a malabsorption of oxalate. In these patients, oxalate becomes more available for absorption 2 , which can cause severe kidney damage and can lead to end-stage renal failure.



OX-1 is a novel oxalate decarboxylase (OxDC) enzyme developed with the support of multiple National Institute of Health (NIH) Small Business Innovation Research (SBIR) Grants. OX-1 demonstrates stability in a wide pH range including very acidic environments; thus, can effectively degrade oxalate in the gastrointestinal tract, in particular the stomach.

In Vitro And In Vivo Safety Evaluation of Ox-1


AA-1(also known as A0) is an oxalate decarboxylase (OxDC) enzyme originating from a fungal source. AA-1 has the potential to degrade oxalate throughout the complete gastrointestinal tract due to its extremely wide pH activity profile with activity in neutral and basic pH range.
