Hyqvia Generic Name & Formulations

General Description

Immune globulin (human) 10%, recombinant human hyaluronidase (rHuPH20) 160U/mL; 2.5g/200U, 5g/400U, 10g/800U, 20g/1600U, 30g/2400U; soln for SC inj; preservative-, sucrose-, latex-free.

Pharmacological Class

Immune globulin + recombinant human hyaluronidase.

How Supplied

Dual vial unit—1

Mechanism of Action

The role of these antibodies and the mechanisms of action of IgG in the Immune Globulin Infusion 10% (Human) of HyQvia have not been fully elucidated.

Hyqvia Indications

Indications

Chronic inflammatory demyelinating polyneuropathy (CIDP) as maintenance therapy to prevent relapse of neuromuscular disability and impairment.

Hyqvia Dosage and Administration

Adult

≥18yrs: Individualize. Infuse 2 components sequentially into abdomen or thighs using an infusion pump, beginning with recombinant human hyaluronidase then immune globulin within 10mins. Maximum infusion volume: (<40kg): 600mL; (≥40kg): 1200mL. If maximum daily dose limit is exceeded or the infusion volume is not tolerated: may give dose over multiple days in divided doses with 48–72hrs between doses at the site. May administer dose at 1, 2, or 3 infusion sites (max volume of 600mL/site or as tolerated). If using 3 sites, max is 400mL/site. Initial infusion rate (recombinant human hyaluronidase): 1–2mL/min per site or as tolerated; (immune globulin): see full labeling. Recommended dose: 80 U/g (rHuPH20/IgG). Prior to initiation, calculate the weekly equivalent dose to plan for the ramp-up schedule. Doses ≤0.4g/kg: may give without a ramp-up. Adjust dose and frequency based on clinical response. Switching from IGIV treatment (must be on stable IGIV doses): give the same dose and frequency as previous IGIV treatment. Give 1st infusion 2 weeks after the last IGIV infusion; 1 week after the 1st dose, give 2nd infusion; see full labeling.

Children

<18yrs: not established.

Hyqvia Contraindications

Contraindications

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

Hyqvia Boxed Warnings

Boxed Warning

Thrombosis.

Hyqvia Warnings/Precautions

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. Nursing mothers.

Hyqvia Pharmacokinetics

Absorption

The AUC of HyQvia compared to conventional IGSC administration was 20% higher. The bioavailability of HyQvia based on weekly AUC was 93.3% relative to IGIV. Time to reach maximum concentration of IgG following HyQvia administration was 5 (3.3–5.1) days.

Elimination

Mean (SD) clearance: 1.6 (0.5) mL/kg/day. Mean (SD) terminal half-life: 59.3 (36.1) days.

Hyqvia Interactions

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.

Hyqvia Adverse Reactions

Adverse Reactions

Local reactions, headache, pyrexia, nausea, fatigue; aseptic meningitis syndrome, hemolysis, infection, TRALI. Also for PI: antibody formation against recombinant human hyaluronidase, vomiting; also for CIDP: erythema, pruritus, increased lipase, abdominal pain, back pain, pain in extremity.

Hyqvia Indications

Indications

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

Hyqvia Dosage and Administration

Adults and Children

<2yrs: not established. 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. ≥2yrs: Recommended dose: 80 U/g (rHuPH20/IgG). Initial interval/dosage ramp-up: 7.5g on Week 1, then 15g on Week 2, then 22.5g on Week 4, then 30g on Week 7. Switching from IGIV treatment: give at same dose and frequency as previous IV treatment after initial dose ramp-up. Exposed to measles: give 400mg/kg as soon as possible and within 6 days of exposure. At risk for future measles exposure: give at least 530mg/kg every 3 to 4 weeks. Switching from IGSC treatment or if IgG IGSC-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.
