LONDON & BRISBANE, Calif.--(BUSINESS WIRE)--GlaxoSmithKline plc (LSE/NYSE: GSK) and Innoviva, Inc. (NASDAQ: INVA) today announced positive headline results from a non-inferiority lung function study, which demonstrated that patients with well-controlled asthma were able to switch to the once-daily Relvar® Ellipta® (fluticasone furoate/vilanterol, FF/VI) 100/25, an inhaled corticosteroid (ICS)/long-acting beta2 agonist (LABA) combination, from the twice-daily Seretide® Accuhaler® (fluticasone propionate /salmeterol, FP/SAL) 250/50, without compromising their lung function.
Patients randomised to FF/VI taken once-daily maintained a lung function comparable with those randomised to the twice-daily FP/SAL [difference +19mL (95% CI: -11mL, +49mL], meeting the study’s primary endpoint, based on the lower bound (-11ml) of the 95% confidence interval falling above the non-inferiority margin of -100mL.
