Olipudase alfa

Olipudase alfa is recombinant human acid sphingomyelinase. It is the first and only enzyme replacement therapy in the world for the treatment of Acid Sphingomyelinase Deficiency (ASMD), also known as Niemann–Pick disease. ASMD is a rare lysosomal storage disease caused by mutations in the SMPD1 gene, leading to a deficiency in acid sphingomyelinase and the abnormal accumulation of the primary ASM substrate, sphingomyelin. Olipudase alfa works to hydrolyze sphingomyelin accumulated in body tissues, such as the lungs, liver, spleen, kidneys, and bone marrow.

Olipudase alfa gained its first global approval in Japan on March 28, 2022. It was later approved by the European Commission on June 28, 2022 and by the FDA on August 31, 2022.
