Dosing
Primary immune deficiency disorder, Wiskott-Aldrich Syndrome, Common Variable Immunodeficiency, X-linked agammaglobulinemia, Severe Combined Immunodeficiency Individualized SC dose administered daily to every 2 weeks; when switching from IGIV, initial weekly dose = prior IGIV dose (g) divided by weeks between doses, multiplied by 1.37.
Polyradiculoneuropathy, Chronic Inflammatory Demyelinating 0.2 g/kg (1 mL/kg) SC per week in 1-2 infusion sessions over 1-2 consecutive days; may increase to 0.4 g/kg per week if symptoms worsen on the lower dose.
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 reaction to human immune globulin or inactive ingredients of HIZENTRA, including polysorbate 80
- Hyperprolinemia Type I or II (HIZENTRA contains L-proline as stabilizer)
- IgA-deficiency with antibodies against IgA and a history of hypersensitivity
- Serious hypersensitivity to efgartigimod alfa products, hyaluronidase, or any excipient of VYVGART HYTRULO (including anaphylaxis and hypotension leading to syncope)

Most common (>=5%) Local infusion-site reactions (swelling, redness, heat, pain, hematoma, itching), headache, diarrhea, fatigue, back pain, nausea, pain in extremity, cough, upper respiratory tract infection, rash, pruritus, vomiting, abdominal pain, migraine, arthralgia, pain, fall, nasopharyngitis
Postmarketing Allergic-anaphylactic reactions (swollen face or tongue, pharyngeal edema, pyrexia, chills, dizziness, hypertension, malaise, tachycardia, flushing), chest discomfort, dyspnea, tremor, burning sensation, infusion site ulcer, infusion site necrosis
Most common (>=10%) Injection site reactions (rash, erythema, pruritus, bruising, pain, urticaria), headache

Postmarketing Hypersensitivity reactions including anaphylaxis and hypotension, infusion/injection-related reactions, worsening of CIDP symptoms when transitioning from intravenous immunoglobulin treatment
Pharmacology
Immune Globulin Subcutaneous (Human), 20% Liquid that supplies a broad spectrum of opsonizing and neutralizing IgG antibodies against a wide variety of bacterial and viral agents; mechanism of action has not been fully elucidated but may include immunomodulatory effects.
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.
