Xembify Professional Information


The most common adverse reactions in ≥ 5% of subjects in the clinical trial were local adverse reactions including infusion site erythema (redness), infusion site pain, infusion site swelling (puffiness), infusion site bruising, infusion site nodule, infusion site pruritus (itching), infusion site induration (firmness), infusion site scab, infusion site edema, and systemic reactions including cough and diarrhea.

Clinical Trials Experience

Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of one drug cannot be directly compared to rates in other clinical trials of another drug and may not reflect the rates observed in clinical practice.

Clinical safety data are based on an open-label, single-arm prospective multi-center study of 49 subjects with primary immunodeficiency (PI) who received subcutaneous XEMBIFY for at least 6 months.

A total of 49 subjects received 1053 XEMBIFY infusions, including 14 subjects between 2 to 16 years of age during the clinical trial. The average number of infusions per subject was 21.5 infusions, median 24 infusions (range 1-26 infusions). There were a total of 390 local infusion site reactions which occurred at a rate per infusion of 0.370 (about 1 in 2.7 infusions). Of these, the most common was infusion site erythema which had a median duration of 24.9 hours. Infusion site swelling, and infusion site pain had median durations of 24.5 and 22.8 hours, respectively. Local infusion site reactions of all kinds by site of infusion (where site of infusion was recorded) occurred in 50.0% and 52.6% of patients during infusions in the abdomen versus thigh, respectively, and across 773 abdominal infusions and 279 thigh infusions rates were 0.184 and 0.735 per infusion, respectively; this corresponds to 1 in 5.4 infusions (for abdomen) and 1 in 1.4 infusions (for thigh). No local infusion site reactions were severe or serious.

The adverse reactions occurring in ≥ 5% of subjects on XEMBIFY in the clinical trial for the duration of the subcutaneous (SC) phase are depicted in the table below which includes all treatment-emergent adverse reactions except infections.

* Including all adverse reactions that occurred after the first dose ofXEMBIFY regardless of causality, excluding infections.
† Number and percentage o f subjects with the adverse reaction.
‡ Rate per infusion is calculated as the total number ofadverse reactions divided by the total number of infusions.

Four subjects discontinued XEMBIFY due to adverse reactions which were infusion site nodules, infusion site discomfort, skin papules/plaques, and arthralgia/myalgia.

Postmarketing Experience

Because postmarketing reporting of adverse reactions is voluntary and from a population of uncertain size, it is not always possible to reliably estimate the frequency of these reactions or establish a causal relationship to product exposure.

The following adverse reactions have been identified and reported during the postmarketing use of immune globulin products administered subcutaneously:

Cardiac disorders: Tachycardia

Nervous system disorders: Tremor and paresthesia

Respiratory, thoracic and mediastinal disorders: Dyspnea and laryngospasm
