This Industry Theatre uses data from SLS to investigate what features of a medicine may impact effectiveness and explores the contribution of effectiveness trials to treatment decisions.
SLS asthma was an open-label randomized controlled trial conducted in UK primary care, which aimed to guide treatment choices by generating effectiveness and safety data in a population representative of everyday clinical practice.
Subjects were initiated on Relvar▼(fluticasone furoate/vilanterol) or continued with usual care (inhaled corticosteroids [ICS] or ICS/long-acting β2-agonists) for 52 weeks; treatments could be adjusted at the prescriber’s discretion as per normal clinical practice.
