Principal Investigator: Christina Cruz, MD

The aim of this study is to investigate the use of benralizumab in patients with eosinophilic CRSwNP, and comorbid asthma, whose severity is consistent with a need for surgery despite ongoing treatment with intranasal corticosteroids and a history of treatment with systemic corticosteroids or prior surgery for CRSwNP. The effect of benralizumab 30 mg on nasal polyps will be assessed on top of standard of care therapy with INCS over a 56-week treatment period.
