Zavesca (Type C)
Currently, there are no FDA-approved therapies for Niemann-Pick Disease, type C in the United States, though a recent controlled study and a series of case reports suggest limited efficacy for miglustat, an inhibitor of glycosphingolipid biosynthesis.
Zavesca© (Miglustat), a medication developed by Actelion Pharmaceuticals, has NOT been approved by the U.S. Food and Drug Administration as a treatment for NPC for patients in the United States. But Zavesca© is an FDA approved medication of Gaucher’s disease, another Lisosomal storage disease. NPC Patients in the United States have gained access to a prescription for Zavesca when the patient’s treating physician has garnered the appropriate authorizations to prescribe.
