Soraprazan (remofuscin), a potassium-competitive acid blocker (P-CAB; formerly called an acid pump antagonist [APA]), is being developed by Katairo GmbH for the treatment of Stargardt's disease and dry age-related macular degeneration (AMD). Clinical development is underway for Stargardt's disease and dry age-related macular degeneration in the Netherlands and Germany. On 13 November 2013, orphan designation was granted by the European Commission to Katairo GmbH, Germany, for soraprazan for the treatment of Stargardt’s disease. Soraprazan is a a highly potent reversible, and fast-acting inhibitor of gastric H,K-ATPase. Soraprazan shows immediate inhibition of acid secretion in various in vitro models and in vivo and was found to be more than 2000-fold selective for H,K-ATPase over Na,K- and Ca-ATPases.

In Vivo Use Guide

Soraprazan was administrated in oral application of 6, 12 and 24 mg/kg/day for 52 weeks in the Cynomolgus monkey.

Route of Administration: Oral

In Vitro Use Guide

Soraprazan has an IC(50) of 0.1 uM if measured with ion leaky vesicles and of 0.19 uM in isolated gastric glands. With a K(i) of 6.4 nM, a K(d) of 26.4 nM, and a B(max) of 2.89 nmol/mg, this compound is a highly potent and reversible inhibitor of the H,K-ATPase.
