CUVITRU is indicated as replacement therapy for primary humoral immunodeficiency (PI) in adult and pediatric patients ≥2 years. CUVITRU is for subcutaneous use only.
The median duration of once-weekly infusions was <1 hour (0.95 hours; range: 0.2-6.4 hours) in the North American clinical study.
*If a patient is 75 kg (165 lb) and has been prescribed 36 g of IVIG per month, you could switch your patient to 12 g of CUVITRU weekly. After the first 2 infusions, subsequent infusions of CUVITRU could be completed in 15 minutes at a rate of 60 mL/h/site using 4 sites simultaneously.
†Infuse first 2 infusions at 10 to 20 mL/h/site.
84.9% (N=4314) of infusions were administered using only 1 or 2 infusion sites (18.5%=1 site; 66.4%=2 sites) in the North American clinical study.
SCIG=subcutaneous immune globulin.

The dosing calculator is meant to be used as a tool to help HCPs make informed decisions about dosing. Takeda is not making dosing recommendations.
CUVITRU: Maximum volume per site is 60 mL/site as tolerated (except for the first 2 infusions for patients <40 kg, for whom the maximum volume is 20 mL/site). Maximum infusion rate is 60mL/h/site as tolerated (after first 2 infusions). Up to 4 sites can be used simultaneously.1

*Monthly dose of CUVITRU is equivalent to current monthly dose of SCIG.
*Monthly dose of CUVITRU is calculated based on a dose adjustment factor of 1.30.
This calculator does not represent every possible weight calculation. Weights begin as 24 lb and increase in 4 lb increments to 288 lb.
See Full Prescribing Information for additional dosage recommendations. A conversion factor of 2.2046 lb/kg is used to convert the patient’s weight to kilograms. The values displayed are rounded to the nearest decimal point.
CUVITRU is available in 1 g, 2 g, 4 g, 8 g, and 10 g vials of IG 20%. The dose must be rounded up or down, based on the physician’s clinical judgement.
