Olipudase alfa, sold under the brand name Xenpozyme, is a medication used to treat of acid sphingomyelinase deficiency (ASMD), previously known as Niemann-Pick disease type A/B or B.[2] Specifically it is used for non-central nervous system (CNS) symptoms.[2][1] It is given by gradual injection into a vein.[2]

Common side events include headache, cough, diarrhea, low blood pressure, and itchiness.[2] Other side effects may include infusion reactions, liver problems, and anaphylaxis.[2] Use in pregnancy may harm the baby.[2] It is an enzyme replacement, being manufactured acid sphingomyelinase (ASM), and thereby improves metabolism of fats.[1]

Olipudase alfa was approved for medical use in Japan, Europe, and the United States in 2022.[1][2] It is also approved in the United Kingdom.[3] In the United States it costs about 7,500 USD per 20 mg as of 2022.[4] It is made by recombinant DNA technology.[2]

Medical use

The highest potential for benefit is in people with chronic visceral forms of ASMD (type B).[1]

Historically referred to as Niemann-Pick disease types A (NPD A) and B (NPD B), ASMD is a genetic disorder.[1] It belongs to the larger family of metabolic disorders called lysosomal storage diseases, in which fats build up within the parts of the body's cells that break down nutrients and other materials.[1] This affects the way cells work and causes them to die, affecting normal functioning of tissues and organs.[1] ASMD is seriously debilitating and life-threatening since the build-up of fatty substances can cause brain damage and swelling of organs such as liver and spleen.[1]


It is given every two weeks.[1] In children an initial dose of 0.03 mg/kg is used while in adults it is started at 0.1 mg/kg.[2] Doses are than increased to 3 mg/kg.[2]


Xenpozyme was the first ASMD-specific treatment.[1]
