Uses for Taliglucerase Alfa

Gaucher Disease

Long-term enzyme replacement therapy in patients with nonneuronopathic (type 1) Gaucher disease (designated an orphan drug by FDA for this use).

Taliglucerase Alfa Dosage and Administration



IV Administration

For solution compatibility information, see Compatibility under Stability.

Administer by IV infusion.

Administer using an inline, low-protein-binding 0.2-µm filter.

Contains no preservatives; use immediately following preparation. (See Storage under Stability.) Discard any unused portions.


Reconstitute using proper aseptic technique.

Determine number of vials to be reconstituted based on patient’s weight and recommended dose of 60 units/kg.

Remove required number of vials from refrigerator prior to reconstitution; do not leave vials at room temperature for >24 hours and do not heat vials (e.g., in a microwave).

Reconstitute each vial containing 200 units of taliglucerase alfa with 5.1 mL of sterile water for injection to provide a solution containing 40 units/mL. Mix gently; do not shake.


Withdraw appropriate dose from reconstituted vials and dilute with 0.9% sodium chloride injection to yield a final volume of 100–200 mL. For pediatric patients, dilute to final volume of 100–200 mL. For adults, may dilute to final volume of 130–150 mL; however, if volume of reconstituted drug alone is equal to or greater than this amount, do not exceed final volume of 200 mL. Mix gently; do not shake.

Slight flocculation (described as translucent fibers) occurs occasionally after dilution.

Rate of Administration

Administer over 1–2 hours. In pediatric patients, initial infusion rate of 1 mL/minute recommended; if tolerated, may increase up to a maximum rate of 2 mL/minute. In adults, an initial infusion rate of 1.2 mL/minute recommended; if tolerated, may increase up to a maximum rate of 2.2 mL/minute. Administer total volume over a period of ≥1 hour.


Pediatric Patients

Gaucher Disease

Pediatric patients ≥4 years of age: 60 units/kg every 2 weeks.

Adjust dosage based on achievement and maintenance of the patient's therapeutic goals.

Patients currently receiving imiglucerase can be switched to taliglucerase alfa at the same dosage.


Gaucher Disease

60 units/kg every 2 weeks.

Adjust dosage based on achievement and maintenance of the patient's therapeutic goals.

Patients currently receiving imiglucerase can be switched to taliglucerase alfa at the same dosage.

Special Populations

No special population dosage recommendations at this time.

Cautions for Taliglucerase Alfa



Sensitivity Reactions


Severe hypersensitivity reactions, including anaphylaxis, reported. Ensure that appropriate medical support is readily available during administration.

Manage hypersensitivity reactions based on severity. If anaphylaxis or other severe hypersensitivity occurs, discontinue taliglucerase alfa immediately and initiate appropriate therapy. For mild reactions, may reduce infusion rate, temporarily interrupt infusion, and/or administer antihistamines, antipyretics, and/or corticosteroids.

Consider risks and benefits of retreatment in patients who experience a severe hypersensitivity reaction. Premedication with antihistamines and/or corticosteroids may prevent subsequent reactions in patients who have experienced a reaction to taliglucerase alfa or other enzyme replacement therapy.

Antibody Formation

Development of antibodies to taliglucerase alfa reported. Although hypersensitivity reactions also occurred in some patients, relationship between antibodies and hypersensitivity not fully understood. Neutralizing antibodies also detected in some patients; effects on therapeutic response not known.

Monitor for presence of antitaliglucerase alfa antibodies in patients who develop hypersensitivity to taliglucerase alfa or other enzyme replacement therapies.

Specific Populations


Insufficient experience in pregnant women; animal studies have not suggested any evidence of adverse embryofetal effects.


Not known whether taliglucerase alfa is distributed into milk. Consider known benefits of breast-feeding along with the woman's need for taliglucerase alfa and any potential adverse effects of the drug or disease on the infant.

Pediatric Use

Use in pediatric patients ≥4 years of age supported by adequate and well-controlled studies in adults. In general, adverse effects are similar between adults and pediatric patients (with exception of vomiting).

Geriatric Use

Insufficient experience in patients ≥65 years of age to determine whether geriatric patients respond differently than younger adults.

Common Adverse Effects

Treatment-naive adults: Headache, arthralgia, fatigue, nausea, dizziness, abdominal pain, pruritus, flushing, vomiting, urticaria.

Patients who switched from imiglucerase to taliglucerase alfa: Arthralgia, headache, extremity pain.

Formal drug interaction studies not performed to date.

Taliglucerase Alfa Pharmacokinetics



Nonlinear pharmacokinetics; greater than dose-proportional increase in exposure observed at doses studied.

No substantial accumulation or change in pharmacokinetics following repeated dosing.



Does not cross blood-brain barrier.

Not known whether taliglucerase alfa distributes into milk.

Special Populations

Clearance in pediatric patients similar to that in adults.



19–37 minutes.




Powder for Injection

2–8°C. Protect from light.

Following reconstitution, 2–8°C for up to 24 hours if protected from light or up to 4 hours at 20–25°C without protection from light.

Following dilution, may store at 2–8°C for up to 24 hours; protect from light. Do not freeze.



Solution Compatibility1


Sodium chloride 0.9%


Advice to Patients
