2.1 Recommended Dosage
Treatment-naïve patients: The recommended dosage for treatment-naïve adult and pediatric patients 4 years of age and older is 60 units per kg of body weight administered every other week as a 60 to 120 minute intravenous infusion.
Patients switching from imiglucerase: Patients currently being treated with imiglucerase for Type 1 Gaucher disease can be switched to ELELYSO. Patients previously treated on a stable dosage of imiglucerase are recommended to begin treatment with ELELYSO at that same dosage when they switch from imiglucerase to ELELYSO Dosage adjustments can be made based on achievement and maintenance of each patient's therapeutic goals [see Clinical Studies (14.2)].
ELELYSO should be reconstituted, diluted, and administered under the supervision of a healthcare professional.
2.2 Preparation Instructions
Each vial of ELELYSO provides 200 units of taliglucerase alfa and is intended for single use only. Do not use the vial more than one time. The reconstitution and dilution steps must be completed using aseptic technique.
ELELYSO should be reconstituted with Sterile Water for Injection and diluted with 0.9% Sodium Chloride Injection, USP, to a final volume of 100 mL to 200 mL, and delivered by intravenous infusion.
Prepare ELELYSO according to the following steps. Use aseptic technique.
-
a.
-
Determine the number of vials to be reconstituted based on the patient's weight and the recommended dose of 60 units/kg, using the following calculations (1–3):
-
(1)
-
Total dose in units = Patient's weight (kg) × dose (units/kg)
-
(2)
-
Total number of vials = Total dose in units divided by 200 units/vial
-
(3)
-
Round up to the next whole vial.
-
b.
-
Remove the required number of vials from the refrigerator. Do not leave these vials at room temperature longer than 24 hours prior to reconstitution. Do not heat or microwave these vials.
-
c.
-
Reconstitute each vial of ELELYSO with 5.1 mL of Sterile Water for Injection to yield a reconstituted product volume of 5.3 mL and a withdrawal volume of 5 mL. Upon reconstitution, mix vials gently. DO NOT SHAKE. Prior to further dilution, visually inspect the solution in the vials;
