Next expected readout: April 2028 · NCT07426458 (registry estimate)
Ventolin
Developed by GlaxoSmithKline
NCT01076322 · Phase 3 · completed
The study randomized participants to treatment sequences and included Ventolin as the active comparator, but it was open-label and small, with an estimated 17 participants. Its primary endpoint, change in FEV1, is a clinical lung-function measure, but no results are posted to show whether the comparison was favorable for Ventolin or met its prespecified objective.
