The FINANCIAL — GlaxoSmithKline on December 2 announced that the European Commission has granted marketing authorisation for Nucala® (mepolizumab) as an add-on treatment for severe refractory eosinophilic asthma in adult patients. As a result Nucala is now approved for use in the 31 European countries covered by the European Medicines Agency (EMA).
Nucala is the first and only approved biologic therapy that targets interleukin-5 (IL-5), which plays an important role in regulating the function of eosinophils, an inflammatory cell known to be important in asthma. It is administered as a 100mg fixed dose subcutaneous injection every four weeks in addition to the patient’s normal respiratory medication, which often comprises high-dose inhaled corticosteroids plus additional medicines including oral corticosteroids, according to GlaxoSmithKline.
“The marketing authorisation of Nucala in the EU is a significant treatment advance for appropriate asthma patients and reinforces GSK’s leadership in respiratory. We are proud that our work in this area, to better understand the specific role eosinophils play in severe asthma, has resulted in the licensing of mepolizumab as the first anti-IL-5 biological treatment. We aim to offer this medicine to patients as soon as possible.” said Eric Dube, Senior Vice President & Head, GSK Global Respiratory Franchise.
The lead investigator of the first proof of concept trial for mepolizumab and an investigator for the Phase III MENSA study, Professor Ian Pavord, University of Oxford, commented: “Patients with severe refractory eosinophilic asthma are not the typical ‘asthma’ patients many people are familiar with. Despite taking high doses of inhaled medications, they struggle to control their asthma. They have particular problems with frequent asthma attacks and can require hospitalisation. Many also take oral corticosteroids to control their symptoms, which we know can lead to side effects that patients often find very difficult to deal with. To be able to offer these patients a treatment that specifically targets the underlying cause of their disease will be an important option.”
The Phase IIb/III clinical development programme for mepolizumab investigated the efficacy and safety of mepolizumab in patients with severe asthma. All patients in studies MEA115588 (MENSA) and MEA115575 (SIRIUS) had peripheral blood eosinophil levels greater than or equal to 150 cells/μL at initiation of treatment or greater than or equal to 300 cells/μL within the past 12 months.
