Innovation to augment the Lysosomal Acid Lipase Deficiency Treatment Market
Lysosomal acid lipase deficiency (LAAL) is an autosomal recessive genetic disorder caused due to mutation in LIPE (Lipase E) gene which encodes the lysosomal acid lipase proteins on chromosome 10q23.31. Thus, due to mutation in LIPE gene there is no enough production of this active enzyme lysosomal acid lipase (LAAL) which leads to lysosomal acid lipase deficiency.
Basic function of lysosomal acid lipase enzyme is to hydrolyze cholesterol
esters and triglycerides. Lysosomal acid lipase deficiency phenotypic spectrum
ranges from infantile to late-onset form, thus leading to two types of
lysosomal acid lipase deficiency autosomal recessive diseases known as wolman
disease and cholesterol ester storage disease (CESD) respectively.
Wolman disease is complete loss of lysosomal acid lipase enzyme occurring in
infants with an incidence of about 1 in 500,000 of live births. It is
characterized by diarrhea, vomiting, weight loss which eventually leads to
malnutrition, hepatomegaly or even death.

Wolman disease results into hepatomegaly and liver disease due to deposition
of cholesterol esters and triglycerides in hepatic macrophages. Wolman disease
also leads to adrenal cortical insufficiency due to calcification of adrenal
glands. It is mandatory in case of infants to undergo successful hematopoietic
stem cell transplantation in order to survive beyond a year. Cholesterol ester
storage disease can also occur in childhood and is characterized by partial
loss of lysosomal acid lipase enzyme production with more varied presentation.
Cholesterol ester storage disease generally occurs late and in most cases is
asymptomatic and underdiagnosed. Cholesterol ester storage disease has
incidence of 1 in 40,000 individual, relatively high in comparison to Wolman
disease. Cholesterol ester storage disease is indicated by hepatosplenomegaly,
abnormalities in serum lipid and/or elevation of hepatic enzymes. Late-onset
morbidity in cholesterol ester storage disease is due to atherosclerosis,
anemia and/or thrombocytopenia, anemia and also liver diseases such as
fibrosis, cirrhosis, and steatosis etc.
Lysosomal acid lipase deficiency results in systemic complications due to
over deposition or accumulation of triglycerides and cholesteryl esters.
Lysosomal acid lipase deficiency is an ultra-rare disease affecting less than
20 patients per million population. Lysosomal acid lipase deficiency mainly
causes multi-organ damage that might lead to death if not treated on time.
Diagnosis of lysosomal acid lipase deficiency is done with help of sequencing
of LIPA gene and also by measuring amount of lysosomal acid lipase enzyme
present in peripheral blood leukocytes, dried blood spots or fibroblasts.
The currently available treatment for lysosomal acid lipase deficiency is
intended to lower the cholesterol and triglycerides level with help of statins
and cholestyramine. Maintaining levels of cholesterol and triglycerides
prevents premature atherosclerosis. The lysosomal acid lipase deficiency
treatment market is expected to drive the market mainly due to the growing
prevalence and lack of approved treatment for it, except for recently approved
drug sebelipase alfa.

This recent approval of sebelipase alfa drug is also expected to drive the
market for lysosomal acid lipase deficiency treatment market. Challenges in
lysosomal acid lipase deficiency treatment market is that unawareness of the
people about LAAL deficiency. The lysosomal acid lipase deficiency treatment
market is also restrained by lack of thorough understanding about the disease
as well as treatment.
The global market for lysosomal acid lipase deficiency treatment, is
segmented on basis of treatment type, disease indication and geography.

Global lysosomal acid lipase deficiency treatment market is segmented on
basis of treatment type into enzyme replacement therapy, kidney transplantation
and stem cell transplantation. FDA approval of drug sebelipase alfa on 8th
December 2015 is considered to be a breakthrough in lysosomal acid lipase
deficiency treatment market and thus enzyme replacement therapy segment is
expected to boost the lysosomal acid lipase deficiency treatment market.
While based on disease indication lysosomal acid lipase deficiency treatment
market is segmented into wolman disease and cholesterol ester storage disease
Cholesterol ester storage disease segment is expected to have a greater share
due to high demand in this segment.

On basis of region or country the lysosomal acid lipase deficiency treatment
market is segmented into North America (NA), Latin America (LA), Europe, Asia Pacific
(APAC), Middle East and Africa (MEA). In terms of region, due to high
prevalence of lysosomal acid lipase deficiency disease, Europe and North
America are expected to boost lysosomal acid lipase deficiency treatment
market.
The major key players in the lysosomal acid lipase deficiency treatment
market are, AstraZeneca plc., Merck & Co., Inc., Pfizer, Inc., Alexion
Pharmaceutical Inc., Lonza Group Ltd., Thermo Fisher Scientific, Teva
Pharmaceutical Industries Ltd.
