fluticasone furoate/vilanterol vs Vilanterol
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.
Vilanterol
Marketed by GlaxoSmithKline
NCT01706198 · Phase 3 · completed
The study randomized 4,233 participants to FF/VI or active usual care, but neither participants nor investigators were blinded. Its primary patient-reported asthma-control endpoint was a surrogate/soft measure and was met in favor of FF/VI (71% vs 56%; p<0.001), supporting moderate rather than strong evidence.
