Infusion rate and volume:
First infusion: Rate of 15 mL/hr/site, volume of 15 mL or less per site
Second to fourth infusion: Rate of 25 mL/hr/site, volume of 15 mL or less per site
Fifth infusion: Rate of 25 mL/hr/site, volume of 20 mL or less per site
Sixth infusion and onward: Rate of 25 mL/hr/site, volume of 25 mL or less per site

Initial weekly dose of Cuvitru(R): [Previous IGIV or Hyqvia(R) dose (in grams)/number of weeks between IGIV doses] x 1.30
Infusion rate and volume:
First 2 infusions:

• Patient weight under 40 kg: Rate of 10 to 20 mL/hr/site, volume of 20 mL or less per site
• Patient weight 40 kg or above: Rate of 10 to 20 mL/hr/site, volume of 60 mL or less per site

Subsequent infusions:

• All patients, regardless of weight: Rate of 60 mL/hr/site or less, volume of 60 mL or less per site

Every 2 week dosing: Start 1 or 2 weeks after last IGIV infusion, or 1 week after last weekly subcutaneous immune globulin infusion. Give twice the calculated weekly dose.

Frequent dosing (2 to 7 times/week): Start 1 week after last IGIV or subcutaneous immune globulin infusion; divide calculated weekly dose by desired number of doses per week.

• Administer at regular intervals from daily up to every 2 weeks.
• For subcutaneous infusion only
• Adjust dose based on clinical response and serum IgG trough levels.
• Inject into 1 to 4 injection sites simultaneously, with at least 2 to 4 inches between sites.
• Adjust infusion rates and volumes as tolerate.

Comments:

• Primary humoral immunodeficiency includes, but is not limited to, common variable immunodeficiency (CVID), X-linked agammaglobulinemia, congenital agammaglobulinemia, Wiskott-Aldrich syndrome, and severe combined immunodeficiencies.

Use(s): Primary humoral immunodeficiency

Precautions

US BOXED WARNING(S): THROMBOSIS

• Thrombosis may occur with immune globulin products.
• Risk factors include: advanced age, prolonged immobilization, hypercoagulable conditions, history of venous or arterial thrombosis, estrogen use, indwelling central venous catheters, hyperviscosity, and cardiovascular risk factors.
• Thrombosis may occur in the absence of known risk factors.

Recommendations:

• For patients at risk of thrombosis, administer at the minimum dose and infusion rate practicable.
• Ensure adequate hydration of patients before administration.
• Monitor for signs and symptoms of thrombosis and assess blood viscosity in patients at risk for hyperviscosity.

Safety and efficacy have not been established in patients younger than 2 years.

Consult WARNINGS section for additional precautions.
