Head-to-head evidence
fluticasone furoate/vilanterol vs salbutamol
Same mechanism, same race: design-graded trial evidence for both assets, with the grading rationale shown. Grades describe the quality of the evidence, never the merits of either security.

fluticasone furoate/vilanterol
Marketed by GlaxoSmithKline
NCT01086384 · Phase 3 · completed
This was a randomized, triple-blind, active-controlled trial with approximately 2,019 treated participants. Its primary hard clinical endpoint—having one or more severe asthma exacerbations—favored fluticasone furoate/vilanterol and was statistically significant.
salbutamol
Developed by GlaxoSmithKline
NCT03528577 · Phase 3 · completed
The study randomized 128 participants in a quadruple-blind, four-period crossover design with active and placebo comparators. However, its primary endpoint was a pharmacodynamic surrogate rather than a hard clinical outcome. Results were not posted at the time of grading; the key result shown was recorded subsequently from the registry record.
