Allergic asthma is an important phenotype and although currently available treatments are effective, about 5% of affected patients have severe, treatment-refractory disease. Despite advances in our understanding of the disease, there remains an unmet need in this group of patients. The most recent and significant advance in treatment has been anti-­immunoglobulin E (IgE) therapy, which improves symptoms and quality of life in patients with severe allergic asthma. Clinical trials are ongoing with novel biologic agents that demonstrate potential efficacy; determining the subsets of patients for which they are suitable will be crucial to ensure cost effectiveness. Personalised medicine and targeted therapies may hold the key to long-term control in this group of patients. ER -
