Therapeutic Use:

Indications for HYQVIA:

Primary immunodeficiency (eg, common variable immunodeficiency, congenital or X-linked agammaglobulinemia, Wiskott-Aldrich syndrome, and severe combined immunodeficiencies).

Adult:

Individualize. Infuse 2 components sequentially into abdomen or thighs using an infusion pump, beginning with recombinant human hyaluronidase then immune globulin within 10 mins. Volume per site: (<40kg): may administer up to 300mL/site; (≥40kg): up to 600mL/site. Initial infusion rate (recombinant human hyaluronidase): 1–2mL/min per site or as tolerated; (immune globulin): see full labeling. Start treatment 1 week after last IgG infusion; increase dose and frequency from 1-week dose to a 3- or 4-week dose. Initial dose: 7.5g on Week 1, then 15g on Week 2, then 22.5g on Week 4, then 30g on Week 7 (see full labeling for initial ramp-up schedule). Switching from IGIV treatment: give at same dose and frequency as previous IV treatment after initial dose ramp-up. Switching from IGSC treatment or if IgG-naive: 300–600mg/kg at 3–4 week intervals after initial ramp-up. Renal dysfunction/failure or thrombosis risk: give at the minimum dose and infusion rate practicable.

Children:

Not established.

Contraindications:

IgA deficiency with antibodies against IgA and history of hypersensitivity. Previous severe reaction to human immune globulin. Known hypersensitivity to hyaluronidase.

Warnings/Precautions:

Advanced age, prolonged immobilization, hypercoagulable conditions, history of venous or arterial thrombosis, use of estrogens, indwelling central vascular catheters, hyperviscosity, cardiovascular disorders: increased risk of thrombosis. Monitor for signs/symptoms of thrombosis and assess blood viscosity in patients at risk for hyperviscosity. Ensure adequate hydration prior to administration. Monitor for aseptic meningitis, hemolysis, delayed hemolytic anemia, transfusion-related acute lung injury (TRALI) (eg, pulmonary edema, dyspnea, hypoxemia). Pre-existing renal insufficiency, diabetes, >65yrs, hypovolemia, sepsis, paraproteinemia: increase risk of renal dysfunction/failure. Correct volume depletion; assess renal function, BUN, serum creatinine, urine output, before and during therapy; consider discontinuing if renal function deteriorates. Contains human plasma; monitor for possible infection transmission. Discontinue if hypersensitivity reactions occur. Pregnancy (Cat.C). Nursing mothers.

Interactions:

Increased risk of renal toxicity with concomitant nephrotoxic drugs. May affect response to live virus vaccinations. May interfere with serological test interpretation. May cause false (+) direct or indirect Coombs' test.

Pharmacological Class:

Immune globulin + recombinant human hyaluronidase.

Adverse Reactions:

Local reactions, headache, antibody formation against recombinant human hyaluronidase, fatigue, nausea, pyrexia, vomiting; aseptic meningitis syndrome, hemolysis, infection, TRALI.

How Supplied:

Dual vial unit—1
