Omalizumab is in clinical development for the treatment of chronic rhinosinusitis with nasal polyps (CRwNP). Chronic rhinosinusitis is a condition in which the lining of the sinuses becomes inflamed. It is characterised by symptoms including nasal congestion, discharge, decreased or loss of sense of smell, facial pain and headache. The condition is referred to as CRSwNP if nasal polyps are also present. Polyps are growths inside the nasal passages and sinuses, which usually only cause problems if they are large or grow in clusters, causing an obstruction. Additional symptoms of nasal polyps include a blocked nose, snoring and disturbed sleep. Corticosteroids are often prescribed for CRSwNP to reduce or eliminate the swelling. Surgery is recommended when the drug treatment fails.
Omalizumab is a monoclonal antibody that targets and blocks the immunoglobulin E (IgE). Human IgE is produced in large quantities in patients with allergies and triggers an allergic reaction in response to an allergen. By attaching to IgE, omalizumab ‘mops up’ the free IgE circulating in the blood. This means that when the body encounters an allergen, there is less IgE available to trigger an allergic reaction. This helps to reduce the symptoms of CRSwNP. If licensed, omalizumab will offer a treatment option as add-on therapy for patients with CRSwNP who have had an inadequate response to current standard-of-care treatments.

Benralizumab in addition to mometasone furoate for severe nasal polyposis
Benralizumab in addition to mometasone furoate is in development for the treatment of severe nasal polyposis/polyps. Nasal polyps are painless soft growths inside the nose. The exact cause is still unknown but asthma and a bad reaction to aspirin are known to increase the risk of developing the disease. Nasal polyps contain inflammatory fluid and …
