CHMP recommends Xolair an add-on therapy with intranasal corticosteroids for the treatment of adults with severe chronic rhinosinusitis with nasal polyps.- Novartis

Novartis has announced that the European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP) has adopted a positive opinion recommending the approval of Xolair (omalizumab) as an add-on therapy with intranasal corticosteroids (INC) for the treatment of adults (18 years and above) with severe chronic rhinosinusitis with nasal polyps (CRSwNP), for whom therapy with INC does not provide adequate disease control. If approved, omalizumab will be the first treatment for nasal polyps specifically targeting and blocking immunoglobulin E (IgE), which helps to reduce the size of nasal polyps (as defined by Nasal Polyps Score; NPS) and improve symptoms. The European Commission reviews the CHMP recommendation and usually delivers its final decision within two months.

“Patients with chronic rhinosinusitis with nasal polyps suffer from persistent symptoms, such as nasal congestion facial pain, loss of sense of smell and taste, difficulty breathing and sleep problems, which can significantly impair their quality of life. Unfortunately, many patients continue to experience symptoms despite standard-of-care, and multiple sinus surgeries,” said Professor Philippe Gevaert, Upper Airway Research Laboratory, Department of Otorhinolaryngology, Ghent University Hospital, Ghent, Belgium. “Omalizumab is specifically designed to block immunoglobulin E, which is a key driver in the inflammatory pathway; if approved, it will provide patients, for whom intranasal corticosteroids do not provide adequate disease control, with a treatment option that has been shown to improve both symptoms and quality of life.”

The CHMP positive opinion is based on results from the Phase III POLYP 1 and 2 studies, which were published in the Journal of Allergy and Clinical Immunology in June 20201. These replicate studies demonstrated that patients treated with omalizumab achieved statistically significant improvements in mean NPS (POLYP 1: -1.08; p<0.0001, POLYP 2: 0.90; p=0.014) and daily Nasal Congestion Score (NCS; POLYP 1: -0.89; p=0.0004, POLYP 2: -0.70; p=0.0017) compared to placebo at Week 241 (co-primary endpoints). All patients received INC (mometasone nasal spray) as background therapy. In both studies, patients treated with omalizumab demonstrated significant improvements in NPS and NCS as early as first assessment (Week 4), compared to placebo
