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 HFA-134a
Developed by GlaxoSmithKline
NCT06261957 · Phase 3 · completed
The study randomized 477 adults and used quadruple blinding with an active salbutamol comparator. Its primary endpoint was the number of participants with adverse events, but no results or statistical comparison are posted, so the outcome is currently unknown.
