Head-to-head evidence
Ciclesonide (XRP1526) vs Fluticasone propionate/salmeterol (Advair HFA)
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.

Ciclesonide (XRP1526)
Developed by Sanofi
NCT00174720 · Phase 3 · completed
In this randomized, double-blind, placebo-controlled Phase 3 trial, 708 patients with asthma were randomized to one of several ciclesonide dosing regimens or placebo. Ciclesonide produced significantly greater improvements in lung function (FEV1) than placebo, both averaged over weeks 12-16 and at week 16 alone.
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.
