SparsentanSparsentan, which possesses two clinically validated mechanisms of action in a single molecule, works by selectively blocking the action of two potent vasoconstrictor and mitogenic agents, angiotensin II (AII) and endothelin 1 (ET1), at their respective receptors. Sparsentan is highly selective (10,000-fold) for the AII receptor sub-type 1 and the ET receptor sub-type A. As such, Sparsentan combines the properties of an angiotensin receptor blocker (ARB) and an endothelin receptor antagonist (ERA) in the same molecule.Phase 3Travere Therapeutics, Inc.Click here for more informationClick here for more information
AtrasentanAtrasentan is a selective and potent inhibitor of the endothelin A receptor, or ETA, which has the potential to provide benefit in multiple chronic kidney diseases by reducing proteinuria and having direct anti-inflammatory and anti-fibrotic effects to preserve kidney function.Phase 2Chinook Therapeutics U.S., Inc.Click here for more informationClick here for more information
