<0.001 EU per 1 μg of the protein by the LAL method
The product is a hydrolytic lysosomal cholesteryl ester and triacylglycerol-specific enzyme indicated for the treatment of patients with a diagnosis of Lysosomal Acid Lipase (LAL) deficiency.
Examples of Clinical Use:
Lysosomal Acid Lipase (LAL) deficiency
Mechanism of action:
LAL deficiency is an autosomal recessive lysosomal storage disorder characterized by a genetic defect resulting in a marked decrease or loss in activity of the lysosomal acid lipase (LAL) enzyme. The primary site of action of the LAL enzyme is the lysosome, where the enzyme normally causes the breakdown of lipid particles including LDL-c. Deficient LAL enzyme activity results in progressive complications due to the lysosomal accumulation of cholesteryl esters and triglycerides in multiple organs, including the liver, spleen, intestine, and the walls of blood vessels. The resulting lipid accumulation in the liver may lead to increased liver fat content and progression of liver disease, including fibrosis and cirrhosis. Lipid accumulation in the intestinal wall leads to malabsorption and growth failure. In parallel, dyslipidemia due to impaired degradation of lysosomal lipid is common with elevated LDL-c and triglycerides and low HDL-cholesterol (HDL-c). Sebelipase alfa binds to cell surface receptors via glycans expressed on the protein and is subsequently internalized into lysosomes. Sebelipase alfa catalyzes the lysosomal hydrolysis of cholesteryl esters and triglycerides to free cholesterol, glycerol and free fatty acids.
Sebelipase alfa is a Recombinant enzyme replacement therapy, also known as Recombinant Lysosomal Acid Lipase (LAL), and its main role is to restore or replenish the activity of the missing enzyme, acid lipase in the body. Acid lipase has a variety of physiological functions in the human body, the most important of which is to maintain the balance of lipid metabolism by decomposing natural lipids. If the acid lipase in the patient is affected by the absence or abnormal function, it will lead to the disorder of lipid metabolism, which can lead to a series of serious diseases. Sebelipase alfa can be administered intravenously to restore or replenish the missing enzyme activity in the body and prevent abnormal accumulation of lipids in cells and tissues. It is mainly used to treat Lysosomal Acid Lipase Deficiency (LAL-D) caused by acid lipase deficiency. The disease is a rare genetic disorder with early neurological and muscular disorders. Sebelipase alfa has been approved and endorsed by clinical trials and relevant regulatory agencies, its safety and efficacy have been demonstrated, and it has been used for the long-term treatment of patients with LAL-D.
2. Clinical application
Sebelipase alfa is mainly used to treat diseases caused by Lysosomal Acid Lipase Deficiency (LAL-D). LAL - D is a rare genetic disease, characterized by the body’s lack of acid lipase activity or abnormality. Sebelipase alfa is indicated for several LAL-D-related disorders: (1) Infantile LAL-D: This is a severe disease that presents in infancy. Patients often show liver and spleen enlargement, abnormal liver function, hepatic failure, and other symptoms associated with adverse lipid metabolism. (2) Pediatric and Adult LAL-D: This form of LAL-D appears during childhood or adulthood. Patients may present with fat accumulation, liver changes, hepatosplenomegaly, hyperlipidemia, and other symptoms related to lipid metabolism. Through Sebelipase alfa supplement the missing acid lipase activity, helps restore the balance of lipid metabolism, and reduce or avoid the abnormal accumulation of lipid in cells and tissues. This helps to improve the patient's symptoms and quality of life and slow the progress of the disease.
3. Advantages and Disadvantages
Sebelipase alfa has the following advantages and disadvantages as an enzyme-replacement therapy: Advantages: (1) Remarkable efficacy: Sebelipase alfa can restore or supplement the activity of acid lipase in the body and effectively prevent abnormal accumulation of lipids in cells and tissues. It has been shown to improve the symptoms caused by LAL - D has a significant curative effect and quality of life. (2) High safety: The drug has been shown to be safe in clinical trials and has received regulatory approval. Although there may be some side effects, they are usually manageable and manageable. (3) Long-term effect: Long-term clinical studies have shown that Sebelipase alfa can maintain long-term stable efficacy, effectively control the progression of the disease, and reduce the risk of LAL-D-related complications under continuous use. Disadvantages: (1) The drug is costly: as a kind of special use drug, Sebelipase alfa's price is higher, which may cause an economic burden to patients and the health care system. (2) Limitation of administration: Sebelipase alfa is mainly administered by intravenous injection, which requires the supervision of a medical institution or professional. This may cause some inconvenience to patients and families. (3) Long duration of treatment: Since LAL-D is a lifelong disease, treatment with Sebelipase alfa usually requires a long duration and may require frequent drug administration. In conclusion, although Sebelipase alfa has significant efficacy and is widely recognized in the treatment of LAL-D, patients and physicians still need to consider its economy and use requirements when selecting and using it. Work with physicians and medical teams for comprehensive evaluation and decision-making to develop the best treatment plan.
4. Pipeline research status
In the case of Sebelipase alfa, only one pipeline is currently in development. This pipeline is primarily targeted for the treatment of Lysosomal Acid Lipase Deficiency (LAL-D), and this study was conducted to further improve and optimize the therapeutic effect of Sebelipase alfa to provide better clinical outcomes and patient experience.
