Acid Sphingomyelinase Deficiency: Disease Understanding and Treatment Algorithm

Acid Sphingomyelinase Deficiency Overview

Acid sphingomyelinase deficiency (ASMD), formerly recognized as Niemann-Pick disease types A, A/B, and B, is a rare autosomal recessive disorder caused by mutations in the SMPD1 gene, leading to a deficiency in acid sphingomyelinase. This enzyme deficiency results in the accumulation of sphingomyelin within cells, primarily affecting the mononuclear phagocytic system. The liver, spleen, lungs, nervous system, and skeletal system are the most impacted organs.

Acid Sphingomyelinase Deficiency Diagnosis

Acid sphingomyelinase deficiency diagnosis begins with a clinical evaluation, identifying symptoms based on type-severe Type A with early neurodegeneration and hepatosplenomegaly, or milder Type B with lung and bone involvement but minimal neurological effects. Diagnosis is confirmed through an enzyme assay measuring acid sphingomyelinase activity in blood or skin cells, supported by liver function and lipid profile tests. Genetic testing of the SMPD1 gene identifies specific mutations, enabling carrier testing and prenatal diagnosis. Imaging studies assess organ involvement, while biopsies are rarely needed. Differential diagnosis excludes similar lysosomal disorders like Gaucher disease. Although newborn screening for acid sphingomyelinase deficiency is not yet routine, ongoing research may soon enable earlier detection and improved outcomes.

Acid Sphingomyelinase Deficiency Treatment

Historically, treatment for acid sphingomyelinase deficiency has been supportive, focusing on symptom management and improving quality of life through regular monitoring and addressing complications like respiratory issues and organ enlargement. The recent development of XENPOZYME (olipudase alfa), a recombinant form of the acid sphingomyelinase enzyme, marks a significant advancement. This therapy aims to reduce sphingomyelin buildup and prevent organ damage, with promising results in clinical trials and approval in the US, Europe, and Japan. Ongoing research into gene therapy, though still experimental, offers potential for long-term treatment or even a cure. Effective acid sphingomyelinase deficiency management typically involves a multidisciplinary team, including geneticists, neurologists, pulmonologists, and other specialists, to address the disease's diverse symptoms and complications.

Acid Sphingomyelinase Deficiency Epidemiology

The acid sphingomyelinase deficiency epidemiology chapter in the report provides historical as well as forecasted epidemiology segmented by the Total Diagnosed Cases of Acid Sphingomyelinase Deficiency, and Total Treated Cases of Acid Sphingomyelinase Deficiency in the 7MM covering the United States, EU4 (Germany, France, Italy, and Spain) and the United Kingdom, and Japan from 2020 to 2034.

• The global incidence is estimated to range from 0.4 to 0.6 cases per 100,000 newborns. These figures are likely underestimated, suggesting that the actual incidence may be higher.
• Acid sphingomyelinase deficiency impacts both males and females equally, showing no significant gender disparity in its prevalence.
• Patients with Niemann-Pick disease type A disease develop symptoms as early as age 3 months. Niemann-Pick disease type B has a variable age of presentation but frequently appears early in childhood, when hepatosplenomegaly is detected and symptoms of lung involvement may occur.

Acid Sphingomyelinase Deficiency Drug Chapters

The drug chapter segment of the acid sphingomyelinase deficiency report encloses a detailed analysis of the approved drug. The drug chapter also helps understand the acid sphingomyelinase deficiency clinical trial details, expressive pharmacological action, agreements and collaborations, and the latest news and press releases.

Approved Drug

XENPOZYME (olipudase alfa): Sanofi

XENPOZYME, a hydrolytic lysosomal sphingomyelin-specific enzyme replacement therapy, is designed to replace deficient or defective acid sphingomyelinase (ASM), an enzyme that allows for the breakdown of the lipid sphingomyelin. In individuals with acid sphingomyelinase deficiency, the deficiency in the ASM enzyme leads to sphingomyelin accumulation in various tissues. XENPOZYME is not expected to cross the blood-brain barrier or modulate CNS manifestations of acid sphingomyelinase deficiency. XENPOZYME has not been studied in patients with acid sphingomyelinase deficiency type A.

XENPOZYME is adminstered intravenously every two weeks, and its administration requires a dose escalation phase followed by a maintenance phase.

In August 2022, the US FDA approved XENPOZYME as first disease-specific treatment for acid sphingomyelinase deficiency. In the US, XENPOZYME received Breakthrough Therapy designation (BTD), which expedites the development and review of drugs intended to treat serious or life-threatening diseases and conditions. The FDA evaluated XENPOZYME under Priority Review, which is reserved for medicines that represent potentially significant improvements in efficacy or safety in treating serious conditions.. In March 2022, XENPOZYME was approved in Japan under the SAKIGAKE (or "pioneer") designation, marking the first approval for olipudase alfa anywhere in the world. In June 2022, the European Commission (EC) approved XENPOZYME for use in Europe.

Drug Class Insight

Enzyme replacement therapy (ERT) for acid sphingomyelinase deficiency is a pivotal treatment that restores deficient sphingomyelinase enzyme activity, thereby mitigating the accumulation of sphingomyelin and alleviating disease symptoms. Administered via intravenous infusion, ERT has been shown to reduce hepatosplenomegaly, improve hematological parameters, and stabilize neurological functions. While effective, ERT requires ongoing administration and is associated with potential side effects such as infusion reactions and allergic responses. The current market includes FDA-approved therapies like olipudase alfa, and research continues to refine treatment protocols and explore combination strategies to enhance patient outcomes and manage long-term treatment challenges.

Acid Sphingomyelinase Deficiency Market Outlook

The acid sphingomyelinase deficiency market remains in its early stages, with significant unmet needs and ongoing research efforts.
