Mirum focuses on finding and developing drugs for difficult-to-treat liver diseases. Our programs are focused on cholestatic liver disease in children and adults.  Our drug candidates, maralixibat and volixibat, target the bile acid accumulation from cholestasis, and we believe our approach can address the underlying cause of symptoms, liver damage, and clinical outcomes.
