Fasenra met both co-primary endpoints of reduced nasal polyp size and blockage in the OSTRO Phase III trial for patients with chronic rhinosinusitis with nasal polyps
High-level results from the OSTRO Phase III trial showed AstraZeneca’s Fasenra (benralizumab) compared with placebo demonstrated a statistically significant improvement in the size of nasal polyps and in nasal blockage in patients with chronic rhinosinusitis with nasal polyps (CRSwNP). Fasenra demonstrated a statistically significant improvement in the endoscopic total nasal polyp score (NPS) and the nasal blockage score (NBS) compared to placebo, in patients with severe bilateral nasal polyposis who were still symptomatic despite continued treatment with standard of care (SoC).
