ELELYSO

Overview

What is ELELYSO?

Taliglucerase alfa, a hydrolytic lysosomal glucocerebroside-specific enzyme for intravenous infusion, is a recombinant active form of the lysosomal enzyme, β-glucocerebrosidase, which is expressed in genetically modified carrot plant root cells cultured in a disposable bioreactor system (ProCellEx®). β-Glucocerebrosidase (β-D-glucosyl-N-acylsphingosine glucohydrolase, E.C. 3.2.1.45) is a lysosomal glycoprotein enzyme that catalyzes the hydrolysis of the glycolipid glucocerebroside to glucose and ceramide.

ELELYSO is produced by recombinant DNA technology using plant cell culture (carrot). Purified taliglucerase alfa is a monomeric glycoprotein containing 4 N-linked glycosylation sites (Mr = 60,800). Taliglucerase alfa differs from native human glucocerebrosidase by two amino acids at the N terminal and up to 7 amino acids at the C terminal. Taliglucerase alfa is a glycosylated protein with oligosaccharide chains at the glycosylation sites having terminal mannose sugars. These mannose-terminated oligosaccharide chains of taliglucerase alfa are specifically recognized by endocytic carbohydrate receptors on macrophages, the cells that accumulate lipid in Gaucher disease.

ELELYSO is supplied as a sterile, non-pyrogenic, lyophilized product. The quantitative composition of each 200 unit vial is D-mannitol (206.7 mg), polysorbate 80 (0.56 mg), sodium citrate (30.4 mg), and taliglucerase alfa (212 units). Citric acid may be added to adjust the pH at the time of manufacture.

A Unit is the amount of enzyme that catalyzes the hydrolysis of 1 micromole of the synthetic substrate para-nitrophenyl-β-D-glucopyranoside (NP-Glc) per minute at 37°C. After reconstitution with Sterile Water for Injection, taliglucerase alfa concentration is 40 units/mL . Reconstituted solutions have a pH of approximately 6.0.

What are the available doses of ELELYSO?

For injection: 200 units, lyophilized powder in single-use vials for reconstitution ()

What should I talk to my health care provider before I take ELELYSO?

How should I use ELELYSO?

ELELYSO is indicated for the treatment of patients with a confirmed diagnosis of Type 1 Gaucher disease.

Treatment-naïve: 60 units/kg administered every other week as a 60 to 120 minute intravenous infusion

Patients switching from imiglucerase: Begin ELELYSO at the same unit/kg dose as the patient's previous imiglucerase dose. Administer ELELYSO every other week as a 60 to 120 minute intravenous infusion. Dosage adjustments can be based on achievement and maintenance of each patient's therapeutic goals.

Clinical Pharmacology

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, a long term 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.

Non-Clinical Toxicology
None.

Prior administration of succinylcholine may enhance the neuromuscular blocking effect of pancuronium and increase its duration of action. If succinylcholine is used before pancuronium bromide, the administration of pancuronium bromide should be delayed until the patient starts recovering from succinylcholine-induced neuromuscular blockade.

If a small dose of pancuronium bromide is given at least 3 minutes prior to the administration of succinylcholine, in order to reduce the incidence and intensity of succinylcholine-induced fasciculations, this dose may induce a degree of neuromuscular block sufficient to cause respiratory depression in some patients.

Other nondepolarizing neuromuscular blocking agents (vecuronium, atracurium, d-tubocurarine, metocurine, and gallamine) behave in a clinically similar fashion to pancuronium bromide. The combination of pancuronium bromide-metocurine and pancuronium bromide-d-tubocurarine are significantly more potent than the additive effects of each of the individual drugs given alone, however, the duration of blockade of these combinations is not prolonged. There are insufficient data to support concomitant use of pancuronium and the other three above mentioned muscle relaxants in the same patient.

Serious hypersensitivity reactions, including anaphylaxis, have occurred in some patients treated with ELELYSO. In clinical trials, 2 of 72 (3%) patients treated with ELELYSO experienced signs and symptoms consistent with anaphylaxis. Signs and symptoms of these patients included urticaria, hypotension, flushing, wheezing, chest tightness, nausea, vomiting, and dizziness. These reactions occurred during ELELYSO infusion.

In clinical trials with ELELYSO, 21 of 72 (29%) patients experienced hypersensitivity reactions, including anaphylaxis. Signs and symptoms of hypersensitivity reactions included pruritus, angioedema, flushing, erythema, rash, nausea, vomiting, cough, chest tightness, and throat irritation. These reactions have occurred up to 3 hours after the start of infusion .

Due to the potential for anaphylaxis, appropriate medical support should be readily available when ELELYSO is administered. Observe patients closely for an appropriate period of time after administration of ELELYSO, taking into account the time to onset of anaphylaxis seen in clinical trials. Inform patients of the signs and symptoms of anaphylaxis, and instruct them to seek immediate medical care should signs and symptoms occur. If anaphylaxis occurs, ELELYSO should be immediately discontinued, and appropriate medical treatment should be initiated.

Management of hypersensitivity reactions should be based on the severity of the reaction and include slowing or temporary interruption of the infusion and/or administration of antihistamines, antipyretics, and/or corticosteroids for mild reactions. Pretreatment with antihistamines and/or corticosteroids may prevent subsequent hypersensitivity reactions. Patients were not routinely premedicated prior to infusion of ELELYSO during clinical studies. If severe hypersensitivity reactions occur, immediately stop the infusion of ELELYSO and initiate appropriate treatment.

Consider the risks and benefits of re-administering ELELYSO in patients who have experienced a severe reaction associated with ELELYSO. Caution should be exercised upon rechallenge, and appropriate medical support should be readily available
