Oxabact® is an oral product composed of highly concentrated live bacteria (Oxalobacter formigenes). OxThera is currently pursuing a complete Oxabact® clinical development program for the treatment of patients suffering from Primary Hyperoxaluria.
Oxazyme® is an oral enzyme, oxalate decarboxylase. The product is designed to break down dietary oxalate in the upper GI tract. The product is developed to treat hyperoxaluria and kidney stones caused by excess intake of dietary oxalate.
About Primary Hyperoxaluria
Primary Hyperoxaluria is a rare inborn autosomal genetic disorder leading to markedly elevated levels of endogenous oxalate in plasma and urine. High levels of oxalate cause kidney damage, including recurrent kidney stone formation and/or calcification of the kidney.
About Secondary Hyperoxaluria
Secondary Hyperoxaluria is resulting from excess intake or super-absorption of oxalate. The prevalence is increasing dramatically in US, Europe and Asia, and the disorder may cause recurrent kidney stones.
Oxabact® holds orphan drug designations in the EU and the US for the treatment of Primary Hyperoxaluria.
