LONDON, UK I June 28, 2017 I GlaxoSmithKline plc (LSE/NYSE: GSK) today announced the submission of a supplemental Biologics License Application (sBLA) to the United States Food and Drug Administration (FDA), seeking approval of mepolizumab, an interleukin-5 (IL-5) antagonist, as an add-on therapy to corticosteroids for the treatment of adult patients with Eosinophilic Granulomatosis with Polyangiitis (EGPA). EGPA is a rare disease, characterised by widespread inflammation in the walls of small blood vessels (vasculitis) which may lead to tissue and organ damage. The disease may affect multiple organ systems and be associated with symptoms of fatigue, muscle and joint pain and weight loss.
Birgitte Volck, head of rare diseases R&D at GSK, said: “The symptoms associated with EGPA are diverse and patients often experience delay in diagnosis. The burden of disease may be severe, preventing patients from carrying out everyday activities and recurrent relapses place them at risk of permanent tissue and organ damage. If approved, mepolizumab will be the first treatment in the US indicated for EGPA and has the potential to offer healthcare professionals and patients a new treatment option to help improve symptoms and disease control.”
The regulatory submission is based on results from a pivotal, 52-week Phase III study which evaluated the efficacy and safety of mepolizumab vs placebo as an add-on therapy to standard of care in patients with relapsing and/or refractory EGPA.
Regulatory filings in other countries are planned during the course of 2017 and 2018. Mepolizumab is not approved anywhere in the world for EGPA.
About EGPA (previously known as Churg-Strauss Syndrome)
Eosinophilic Granulomatosis with Polyangiitis (EGPA) is a rare disease that causes inflammation in the walls of small blood vessels (or vasculitis). The global incidence is generally reported to be in the range 1–4 per million, with an estimated prevalence of approximately 14–45 per million. The mean age of diagnosis is 48 years and the disease can be life-threatening for some patients.
In EGPA, patients usually develop asthma initially, before the vasculitis extends to inflammation in the walls of small blood vessels that supply tissues in the lungs, sinuses, skin, nerves and other organs. EGPA can result in damage to multiple organs in the body and the symptoms common to most include extreme fatigue, weight loss, muscle and joint pain, sinonasal symptoms and breathlessness, all of which affect patients’ ability to carry out everyday activities without difficulty.
The current approach to disease management is primarily based on reduction of active inflammation and suppression of the immune response through the use of corticosteroid therapy and concomitant immunosuppressive therapy (e.g., methotrexate, azathioprine, mycophenolate mofetil) and/or cytotoxic agents (e.g., cyclophosphamide). Although the use of these treatments can be effective for establishing remission, patients remain vulnerable to either the complications of the long-term use of these therapies, or to the risk of relapse, particularly if the dose of corticosteroid is reduced.
About mepolizumab
Mepolizumab is a targeted anti-IL-5 monoclonal antibody. Mepolizumab binds to the signalling protein IL-5, preventing it from binding to its receptor on the surface of white blood cells called eosinophils. Inhibiting IL-5 binding in this manner reduces blood, tissue and sputum eosinophil levels.
Eosinophils are believed to play a role in protecting the body against infection. In some people, increased eosinophil levels can lead to inflammation and play a role in the development of some inflammatory diseases.
Mepolizumab has been developed for the treatment of diseases that are driven by inflammation caused by eosinophils. Mepolizumab is approved for use in the US, under the brand name Nucala, as the first-in-class add-on maintenance treatment for patients with severe asthma aged 12 years and older, and with an eosinophilic phenotype. Nucala has also been approved for severe eosinophilic asthma in the EU, Japan and a number of other countries worldwide although the details of the indications may vary. Trademarks are owned by or licensed to the GSK group of companies.
Mepolizumab is not approved anywhere in the world for EGPA.
Mepolizumab is also being investigated in chronic obstructive pulmonary disease (in phase III), eosinophilic granulomatosis with polyangiitis (EPGA, also referred to as Churg-Strauss syndrome, in phase III), severe hypereosinophilic syndrome (in phase III), and severe atopic dermatitis (phase II).
