Head-to-head evidence
Fluticasone propionate/salmeterol (Advair HFA) vs GW815SF
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 propionate/salmeterol (Advair HFA)
Marketed by GlaxoSmithKline
NCT00158834 · Phase 3 · completed
The study randomized 200 children and used double blinding with an active fluticasone comparator. Its primary endpoint was the clinical measure of asthma symptom-free days, but no results are posted, so whether that endpoint was met cannot be determined.
GW815SF · Advair HFA
Marketed by GlaxoSmithKline
NCT00448435 · Phase 3 · completed
The 51 participants were randomized to treatment sequences and received an active comparator, but the trial was not blinded. Its primary morning PEF endpoint met the prespecified equivalence margin, while the endpoint was a physiologic surrogate rather than a hard clinical or endoscopic measure, supporting a moderate evidence grade.
