Administer by IV infusion. 1 Administer using an inline, low-protein-binding 0.2-mcm filter. 1 Contains no preservatives; use immediately following preparation. 1 (See Storage under Stability.) Discard any unused portions. 1 Reconstitution Reconstitute using proper aseptic technique. 1 Determine number of vials to be reconstituted based on patient s weight and recommended dose of 60 units/kg. 1 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). 1 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. 1 Mix gently; do not shake. 1 Dilution Withdraw appropriate dose from reconstituted vials and dilute with 0.9% sodium chloride injection to yield a final volume of 100 200 mL. 1 For pediatric patients, dilute to final volume of 100 200 mL. 1 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. 1 Mix gently; do not shake. 1 Slight flocculation (described as translucent fibers) occurs occasionally after dilution. 1 Rate of Administration Administer over 1 2 hours. 1 In pediatric patients, initial infusion rate of 1 mL/minute recommended; if tolerated, may increase up to a maximum rate of 2 mL/minute. 1 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. 1 Administer total volume over a period of 1 hour. 1 Dosage Pediatric Patients Gaucher Disease IV Pediatric patients 4 years of age: 60 units/kg every 2 weeks. 1 Adjust dosage based on achievement and maintenance of the patient's therapeutic goals. 1 Patients currently receiving imiglucerase can be switched to taliglucerase alfa at the same dosage. 1 Adults Gaucher Disease IV 60 units/kg every 2 weeks. 1 Adjust dosage based on achievement and maintenance of the patient's therapeutic goals. 1 Patients currently receiving imiglucerase can be switched to taliglucerase alfa at the same dosage. 1 Special Populations No special population dosage recommendations at this time. 1 Cautions for Taliglucerase Alfa Contraindications No known contraindications. 1 Warnings/Precautions Sensitivity Reactions Hypersensitivity Severe hypersensitivity reactions, including anaphylaxis, reported. 1 Ensure that appropriate medical support is readily available during administration. 1 Manage hypersensitivity reactions based on severity. 1 If anaphylaxis or other severe hypersensitivity occurs, discontinue taliglucerase alfa immediately and initiate appropriate therapy. 1 For mild reactions, may reduce infusion rate, temporarily interrupt infusion, and/or administer antihistamines, antipyretics, and/or corticosteroids. 1 Consider risks and benefits of retreatment in patients who experience a severe hypersensitivity reaction. 1 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. 1 Antibody Formation Development of antibodies to taliglucerase alfa reported. 1 7 Although hypersensitivity reactions also occurred in some patients, relationship between antibodies and hypersensitivity not fully understood. 1 Neutralizing antibodies also detected in some patients; effects on therapeutic response not known. 1 Monitor for presence of antitaliglucerase alfa antibodies in patients who develop hypersensitivity to taliglucerase alfa or other enzyme replacement therapies. 1 Specific Populations Pregnancy Insufficient experience in pregnant women; animal studies have not suggested any evidence of adverse embryofetal effects. 1 Lactation Not known whether taliglucerase alfa is distributed into milk. 1 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. 1 Pediatric Use Use in pediatric patients 4 years of age supported by adequate and well-controlled studies in adults. 1 In general, adverse effects are similar between adults and pediatric patients (with exception of vomiting). 1 Geriatric Use Insufficient experience in patients 65 years of age to determine whether geriatric patients respond differently than younger adults. 1 Common Adverse Effects Treatment-naive adults: Headache, arthralgia, fatigue, nausea, dizziness, abdominal pain, pruritus, flushing, vomiting, urticaria. 1 Patients who switched from imiglucerase to taliglucerase alfa: Arthralgia, headache, extremity pain. 1 Interactions for Taliglucerase Alfa Formal drug interaction studies not performed to date. 8 Taliglucerase Alfa Pharmacokinetics Absorption Bioavailability Nonlinear pharmacokinetics; greater than dose-proportional increase in exposure observed at doses studied. 1 No substantial accumulation or change in pharmacokinetics following repeated dosing. 1 Distribution Extent Does not cross blood-brain barrier. 4 Not known whether taliglucerase alfa distributes into milk. 1 Special Populations Clearance in pediatric patients similar to that in adults. 1 Elimination Half-life 19 37 minutes. 1 Stability Storage Parenteral Powder for Injection 2 8 C. Protect from light. 1 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. 1 Following dilution, may store at 2 8 C for up to 24 hours; protect from light. 1 Do not freeze. 1 Compatibility For information on systemic interactions resulting from concomitant use, see Interactions. Parenteral Solution Compatibility 1 Compatible Sodium chloride 0.9% Actions Replaces the deficient endogenous enzyme (glucocerebrosidase) in patients with Gaucher disease. 1 3 4 Gaucher disease is an autosomal recessive lysosomal storage disorder characterized by a deficiency of the enzyme glucocerebrosidase, which results in accumulation of glucocerebroside within the lysosomes of macrophages in the liver, spleen, bone marrow, and other organs; clinical manifestations include hepatosplenomegaly, anemia, thrombocytopenia, and skeletal complications (e.g., osteopenia, osteonecrosis, progressive joint destruction, fractures). 3 4 5 6 8 9 Enzyme replacement therapy in patients with type 1 Gaucher disease increases the degradation of glucocerebroside to glucose and ceramide, with resultant reduction in liver and spleen size, amelioration of anemia and thrombocytopenia, and increased bone remineralization. 1 3 6 7 8 Advice to Patients Importance of informing patients that taliglucerase alfa is administered under the supervision of a clinician by IV infusion (over 1 2 hours) every other week. 1 Risk of severe hypersensitivity reactions, including anaphylaxis. 1 Advise patients of the possible signs and symptoms of a hypersensitivity reaction and to seek immediate medical care if such manifestations occur. 1 Importance of informing clinicians of existing or contemplated concomitant therapy, including prescription and OTC drugs and herbal supplements, as well as any concomitant illnesses. 1 Importance of women informing clinicians if they are or plan to become pregnant or plan to breast-feed. 1 Importance of informing patients of other important precautionary information. 1 (See Cautions.)
