FDA approved Fasenra (benralizumab) for Severe Eosinophilic Asthma and EGPAFDA approved new drug Fasenra for severe asthma and rare disease.

Fasenra is an interleukin-5 receptor alpha-directed cytolytic monoclonal antibody (IgG1, kappa). It binds to the alpha subunit of the IL-5 receptor, which is expressed on eosinophils and basophils, leading to antibody-dependent cell-mediated cytotoxicity, reducing eosinophil levels.

Fasenra is indicated for: - Add-on maintenance treatment of adult and pediatric patients aged 6 years and older with severe asthma and with an eosinophilic phenotype. - Treatment of adult patients with eosinophilic granulomatosis with polyangiitis (EGPA).
