Taliglucerase Alfa (1 brand name, 1 dosage form, 1 route)
Available dosage forms: POWDER.
Routes of administration: INTRAVENOUS.
Brand Names
- ELELYSO
Boxed Warning
Patients treated with enzyme replacement therapies have experienced life‑threatening hypersensitivity reactions, including anaphylaxis. Anaphylaxis has occurred during the early course of enzyme replacement therapy and after extended duration of therapy. Initiate ELELYSO in a healthcare setting with appropriate medical monitoring and support measures, including access to cardiopulmonary resuscitation equipment. If a severe hypersensitivity reaction (e.g., anaphylaxis) occurs, discontinue ELELYSO and immediately initiate appropriate medical treatment, including use of epinephrine. Inform patients of the symptoms of life‑threatening hypersensitivity reactions, including anaphylaxis and to seek immediate medical care should symptoms occur [see Warnings and Precautions (5.1) ].
Indications and Usage
ELELYSO is indicated for the treatment of patients 4 years of age and older with a confirmed diagnosis of Type 1 Gaucher disease.
Contraindications
None.
Mechanism of Action
Gaucher disease is an autosomal recessive disorder caused by mutations in the human glucocerebrosidase gene, which results in a reduced activity of the lysosomal enzyme glucocerebrosidase. Glucocerebrosidase catalyzes the conversion of the sphingolipid glucocerebroside into glucose and ceramide. The enzymatic deficiency results in accumulation of substrate glucocerebroside primarily in the lysosomal compartment of macrophages, giving rise to foam cells or “Gaucher cells,” which accumulate in the liver, spleen and bone marrow. ELELYSO, an enzyme replacement therapy, is a recombinant analog of human lysosomal glucocerebrosidase that catalyzes the hydrolysis of glucocerebroside to glucose and ceramide, reducing the amount of accumulated glucocerebroside. ELELYSO uptake into cellular lysosomes is mediated by binding of ELELYSO mannose oligosaccharide chains to specific mannose receptors on the cell surface leading to internalization and subsequent transport to the lysosomes.
