Acid Sphingomyelinase Deficiency Market Set to Expand with Enzyme Replacement Therapies – BIS Research

The global acid sphingomyelinase deficiency market is transitioning from a niche segment into a dynamic therapeutic area. With the U.S. FDA’s 2022 approval of Xenpozyme (olipudase alfa) for non-CNS manifestations of ASMD, the market outlook has strengthened considerably. This landmark therapy has improved treatment access across the U.S., EU, and Japan, leading to better diagnosis, enhanced patient care, and expansion of the overall rare disease market. Despite barriers such as high treatment costs, diagnostic delays, and small patient populations, the ASMD market is expected to witness steady growth as clinical innovation accelerates, and healthcare systems adapt to the rare disease burden.
Published 09 September 2025

What Is Acid Sphingomyelinase Deficiency (ASMD)? 

Acid sphingomyelinase deficiency (ASMD) is a rare lysosomal storage disorder caused by mutations in the SMPD1 gene, resulting in reduced or absent activity of the acid sphingomyelinase enzyme. This leads to accumulation of sphingomyelin in organs such as the liver, spleen, lungs, and sometimes the central nervous system, causing progressive dysfunction. 

The disease is classified into three main types: 

  • Type A: Severe neurovisceral form, typically fatal in early childhood. 
  • Type B: Chronic visceral form, primarily affecting the liver and spleen, with longer survival prospects. 
  • Type C: Mixed form, with both visceral and neurological manifestations of varying severity. 

Although challenging to manage, recent therapeutic advances such as enzyme replacement therapy provide a new path toward improving patient outcomes. 

What Is the Market Outlook?


  • Therapy Innovation: The launch of enzyme replacement therapy (ERT) – Xenpozyme – has reshaped the treatment landscape, providing the first disease-modifying option for ASMD. 
  • Rising Awareness & Diagnosis: With approved therapies available, healthcare providers are increasingly screening for ASMD, boosting early detection rates. 
  • R&D Momentum: Ongoing pipeline studies and clinical trials aim to address unmet needs, particularly for CNS-involved subtypes. 


How Fast Is the Market Growing? 

While the ASMD market remains relatively small compared to broader genetic disorder markets, it is expected to grow steadily over the forecast period. Growth is being driven by: 

  • Wider global adoption of Xenpozyme. 
  • Expansion of newborn screening and rare disease registries. 
  • Rising investments in rare disease R&D and patient advocacy programs.
