GlaxoSmithKline plc (GSK) today announced that the US Food and Drug Administration (FDA) has approved Nucala (mepolizumab), a monoclonal antibody that targets interleukin-5 (IL-5), as a treatment for patients with chronic rhinosinusitis with nasal polyps (CRSwNP). This new indication for mepolizumab is for the add-on maintenance treatment of CRSwNP in adult patients 18 years of age and older with inadequate response to nasal corticosteroids.

CRSwNP accounts for 2-4% of the US population, affecting more than 5 million people. CRSwNP is one of a variety of diseases arising from inflammation in different tissues associated with elevated levels of a type of white blood cell called eosinophils. It is often characterised by raised eosinophil levels, in which soft tissue growth, known as nasal polyps, develop in the sinuses and nasal cavity. CRSwNP can cause chronic symptoms such as nasal obstruction, loss of smell, facial pressure and nasal discharge.

Mepolizumab is the first anti-IL-5 biologic to be approved for adult patients with CRSwNP in the US.

Dr. Hal Barron, Chief Scientific Officer and President R&D, GSK said: “More than 5 million people in the US suffer with chronic rhinosinusitis with nasal polyps and today’s approval provides these patients with the first anti-IL-5 treatment option and an alternative to surgery to help reduce symptoms of this disease. GSK is committed to exploring the role of IL-5 inhibition in eosinophil-driven diseases to help address unmet needs of patients.”

Tonya Winders, CEO & President, Allergy and Asthma Network (AAN) and President of Global Allergy and Airways Patient Platform (GAAPP) commented: “Patients with chronic rhinosinusitis with nasal polyps experience unpleasant symptoms across a range of severities. As there have been limited treatment options, particularly for those patients with severe disease, they may rely on oral steroids and recurrent surgery to manage their condition. We welcome the news that mepolizumab will now offer appropriate patients and healthcare providers a novel treatment option and alternative to surgery.”

The approval of mepolizumab as a treatment for CRSwNP is based on data from the pivotal SYNAPSE study which explored the effect of mepolizumab vs. placebo in over 400 patients with CRSwNP. Mepolizumab achieved significant improvement in reducing the size of nasal polyps and nasal obstruction. All patients in the study received standard care, had a history of previous surgery (approximately one in three had ≥3 surgeries) and were in need of further surgery due to severe symptoms and increased size of their polyps. SYNAPSE showed that there was a 57% reduction in the proportion of patients who had surgery in the group treated with mepolizumab vs. placebo, HR=0.43 (95% CI 0.25, 0.76). In addition, the proportion of patients requiring systemic corticosteroid use during the 52-week treatment period was lower in patients who received mepolizumab.
