Xembify Indications
Indications
Primary humoral immunodeficiency (eg, congenital or X-linked agammaglobulinemia, common variable immunodeficiency, Wiskott-Aldrich syndrome, severe combined immunodeficiencies).
Xembify Dosage and Administration
Adults and Children
<2yrs: not established. Give by SC infusion into abdomen, thigh, upper arm, sides, back and/or lateral hip. May use up to 6 infusion sites (≥2 inches apart) simultaneously; rotate sites with each infusion avoiding bony areas. Before switching to Xembify, obtain serum IgG trough level to guide subsequent dose adjustments. ≥2yrs: Individualize. Switching from IGIV: initiate 1 week after last IGIV; convert monthly dose into equivalent weekly dose. Initial weekly dose = (prior IGIV [in grams]/number of weeks between IGIV doses) × 1.37. Infuse as tolerated up to max 25mL per infusion site at max rate 25mL/hr/site. For frequent dosing (2–7 times per week): divide calculated weekly dose by desired number of times per week. Dose adjustments: measure serum IgG trough levels as early as 5 weeks after initiation and every 2–3 months based on adequate clinical response (see full labeling). Switching from IGSC: use same weekly dose (in grams) as prior IGSC treatment. Thrombosis risk: give at minimum dose and/or infusion rate practicable.
