Eosinophilic granulomatosis with polyangiitis (EGPA)

Active Ingredient: Benralizumab

Indication for Benralizumab

Population group: only adults (18 years old or older)
Therapeutic intent: Curative procedure

Benralizumab is indicated as an add-on treatment for adult patients with relapsing or refractory eosinophilic granulomatosis with polyangiitis.

For this indication, competent medicine agencies globally authorize below treatments:

30 mg once every 4 weeks

For:

Dosage regimens

Subcutaneous, 30 milligrams benralizumab, once every 4 weeks.

Detailed description

The recommended dose of benralizumab is 30 mg by subcutaneous injection every 4 weeks.

Patients who develop life-threatening manifestations of EGPA should be evaluated for the need for continued therapy, as Fasenra has not been studied in this population.

Benralizumab is intended for long-term treatment. A decision to continue the therapy should be made at least annually based on disease severity, level of exacerbation control and blood eosinophil counts.

Missed Dose

If an injection is missed on the planned date, dosing should resume as soon as possible on the indicated regimen; a double dose must not be administered.

Dosage considerations

It should be injected into the thigh or abdomen. If the healthcare professional or caregiver administers the injection, the upper arm can also be used. It should not be injected into areas where the skin is tender, bruised, erythematous, or hardened.

Active ingredient

Benralizumab

Benralizumab is an anti-eosinophil, humanised afucosylated, monoclonal antibody (IgG1, kappa). It specifically binds to the alpha subunit of the human interleukin-5 receptor (IL-5Rα). The IL-5 receptor is specifically expressed on the surface of eosinophils and basophils. The absence of fucose in the Fc domain of benralizumab results in high affinity for FcɣRIII receptors on immune effector cells such as natural killer (NK) cells. This leads to apoptosis of eosinophils and basophils through enhanced antibody-dependent cell-mediated cytotoxicity (ADCC), which reduces eosinophilic inflammation.
