Abstract
The Salford Lung Study in asthma (SLS-Asthma) is the first prospective, randomized, controlled clinical trial conducted in conditions and in population that were very close to real clinical practice. The study demonstrated that treatment of a large heterogeneous population of asthma patients using combination of vilanterol (VI) and fluticasone furoate (FF) (22/92 mg q.d. or 22/184 mg q.d.) via Ellipta dry powder inhaler provided better control of the disease than the conventional therapy administered by an attendant physician. The level of asthma control in VI/FF group was consistently maintained for 12 months with no identified change in risk of development of serious adverse events. Results were similar in patients receiving ICS or ICS/LABA combinations and did not depend on smoking status or number of exacerbations over the previous year.
