GlaxoSmithKline plc announced results from the paediatric ‘LABA’ (long acting beta2-agonist) safety study. VESTRI (SAS115358) compared Advair® Diskus® (FSC), a combination of the LABA, salmeterol, and the inhaled corticosteroid (ICS), fluticasone propionate (FP), to FP monotherapy in children aged 4 – 11 years. The study assessed the composite endpoint of serious asthma-related events (deaths, intubations or hospitalisations).
