Xenpozym (olipudase alfa) — Uses, Dosage, Side Effects & Safety

Drug class: Enzyme Replacement Therapy

Overview

Xenpozym is a prescription medication used to treat non-central nervous system manifestations of acid sphingomyelinase deficiency (ASMD), also known as Niemann-Pick disease types A and B. ASMD is a rare genetic disorder where the body lacks the enzyme acid sphingomyelinase, leading to the buildup of harmful substances in organs such as the liver, spleen, and lungs. Xenpozym contains olipudase alfa, a recombinant form of the missing enzyme. By replacing this enzyme, Xenpozym helps break down sphingomyelin, reducing its accumulation and improving organ function. Patients may notice improvements in liver and spleen size, lung function, and overall symptoms. Key points for patients: Xenpozym is given as an intravenous infusion under medical supervision. Regular monitoring is required to assess response and detect any side effects. It is not a cure for ASMD but can help manage symptoms and improve quality of life.
