Share

FDA has issued AstraZeneca a complete response letter on its supplemental BLA for Fasenra (benralizumab) for patients with inadequately controlled chronic rhinosinusitis with nasal polyps (CRSwNP). The agency letter is requesting additional clinical data, according to the company. It notes the submission “included data from the OSTRO Phase 3 trial, which met both co-primary endpoints with a safety profile consistent with the known profile of the medicine. AstraZeneca says it is working with FDA on its “next steps,” adding that currently a second Phase 3 trial, ORCHID, in this indication is ongoing. Fasenra is currently approved as an add-on maintenance treatment for severe eosinophilic asthma.
