Dosing
Common Variable Immunodeficiency, X-linked agammaglobulinemia, Congenital agammaglobulinemia, Wiskott-Aldrich Syndrome, Severe Combined Immunodeficiency 300 to 600 mg/kg SC every 3 to 4 weeks after initial ramp-up from 1-week to full dose; rHuPH20 at 80 U/g IgG infused immediately before each IgG dose at each infusion site.
Polyradiculoneuropathy, Chronic Inflammatory Demyelinating Same dose and frequency as prior IGIV treatment SC, typical dosing interval 4 weeks; rHuPH20 at 80 U/g IgG infused immediately before each IgG dose; ramp-up recommended based on tolerability.
Myasthenia Gravis, Generalized 1,000 mg efgartigimod alfa/10,000 units hyaluronidase SC once weekly for 4-week cycles (prefilled syringe over 20-30 seconds) or 1,008 mg/11,200 units (vial over 30-90 seconds); subsequent cycles based on clinical evaluation.
Polyradiculoneuropathy, Chronic Inflammatory Demyelinating 1,000 mg efgartigimod alfa/10,000 units hyaluronidase SC once weekly (prefilled syringe over 20-30 seconds) or 1,008 mg/11,200 units (vial over 30-90 seconds); continue based on clinical response.
Contraindications
- History of anaphylactic or severe systemic reactions to IgG administration
- IgA deficiency with antibodies to IgA and a history of hypersensitivity
- Known systemic hypersensitivity to hyaluronidase including rHuPH20
- Known systemic hypersensitivity to human albumin (in the hyaluronidase solution)
- Serious hypersensitivity to efgartigimod alfa products, hyaluronidase, or any excipient of VYVGART HYTRULO (including anaphylaxis and hypotension leading to syncope)
Adverse Reactions
Most common (>5%) Local infusion site reactions (discomfort/pain, erythema, swelling/edema, pruritus), headache, fatigue, nausea, pyrexia, vomiting
Postmarketing Hypersensitivity, influenza-like illness, infusion site leaking, anaphylactic reaction, tremor, tachycardia, hypotension, infusion related reaction, dyspnea, paresthesia oral, dermatitis allergic, injection site rash, alanine aminotransferase increased
Most common (>=10%) Injection site reactions (rash, erythema, pruritus, bruising, pain, urticaria), headache
Serious Infections, hypersensitivity reactions (including anaphylaxis and hypotension), infusion/injection-related reactions
Postmarketing Hypersensitivity reactions including anaphylaxis and hypotension, infusion/injection-related reactions, worsening of CIDP symptoms when transitioning from intravenous immunoglobulin treatment
Pharmacology
Immune globulin (IgG) replacement product in which the Immune Globulin Infusion (Human), 10% supplies broad-spectrum opsonizing and neutralizing IgG antibodies against bacterial and viral agents, while rHuPH20 transiently depolymerizes subcutaneous hyaluronan to increase tissue permeability, facilitating dispersion and absorption of the full IgG dose administered subcutaneously.
Efgartigimod alfa, a human IgG1 Fc fragment, binds to the neonatal Fc receptor (FcRn) and reduces circulating IgG; co-formulated hyaluronidase transiently depolymerizes hyaluronan to increase subcutaneous tissue permeability for 24 to 48 hours.
