Benralizumab emerges as a groundbreaking treatment for nasal polyps, offering hope to those with severe eosinophilic asthma and chronic rhinosinusitis. By targeting eosinophils, this monoclonal antibody reduces inflammation and improves symptoms. Clinical trials and real-world data underscore its efficacy and safety, paving the way for enhanced management of nasal polyps and related conditions.
Understanding Benralizumab and Nasal Polyps
Nasal polyps are non-cancerous growths that develop in the lining of the nasal passages or sinuses, often associated with chronic rhinosinusitis. These growths can lead to breathing difficulties, reduced sense of smell, and frequent sinus infections. Benralizumab, a monoclonal antibody, has emerged as a promising treatment for managing nasal polyps, particularly in patients with severe eosinophilic asthma (SEA) and chronic rhinosinusitis with nasal polyps (CRSwNP) (source).
The Mechanism of Benralizumab
Benralizumab works by targeting the interleukin-5 (IL-5) receptor alpha on eosinophils, a type of white blood cell involved in inflammatory responses. By binding to this receptor, benralizumab induces apoptosis, or programmed cell death, of eosinophils. This action reduces inflammation and helps control symptoms associated with nasal polyps and asthma (source).
Clinical Evidence Supporting Benralizumab
Several studies have demonstrated the efficacy of benralizumab in managing nasal polyps. The ANANKE study highlighted its long-term effectiveness in reducing the annual exacerbation rate (AER) in SEA patients with CRSwNP. Notably, CRSwNP patients experienced a 100% reduction in severe AER after 96 weeks of treatment. Additionally, these patients showed faster improvements in lung function and a complete reduction in oral corticosteroid use by 48 weeks (source).
The OSTRO Phase III trial further supports benralizumab’s efficacy, showing significant improvements in nasal polyp size and nasal blockage in patients with CRSwNP. The trial involved 413 patients and demonstrated statistically significant improvements in both the endoscopic total nasal polyp score (NPS) and mean nasal blockage score (NBS) at week 40 compared to placebo (source).
Real-World Outcomes and Safety
Real-world observational data also support the use of benralizumab in managing nasal polyps. A study involving 25 patients with severe eosinophilic asthma and CRSwNP reported significant improvements in sinonasal outcomes, as measured by the Sino-nasal Outcome Test−22 (SNOT-22) and Nasal Polyp Score (NPS). Over 24 months, the mean SNOT-22 score decreased from 57 to 26, and the mean NPS decreased from 5.11 to 2.37. Improvements in olfactory function and a reduction in the need for oral corticosteroids and surgery were also observed (source).
Benralizumab’s safety profile is favorable, with no significant adverse events leading to treatment discontinuation reported in studies. This makes it a viable option for patients seeking long-term management of nasal polyps and associated conditions (source).
