The company is focused on the development of injectable pentosan polysulfate sodium (iPPS/PPS) for the treatment of osteoarthritis (OA) and mucopolysaccharidosis (MPS). PPS is a semi-synthetic drug manufactured from the wood chips of European beech trees. Extracted glucurono-xylans are sulfated to produce a negatively charged product that mimics glycosaminoglycans. The company develops PPS under the brand name Zilosul. Other indications under investigation for PPS include the treatment of joint function, mobility, and pain in patients with mucopolysaccharidoses; treating alphavirus-induced arthralgia; chronic heart failure; acute respiratory distress syndrome; and allergic respiratory conditions. The company is also advancing early formulation development for Pentacoxib, an oral combination of PPS and a COX-2 inhibitor targeting patients with earlier-stage OA.
