Head-to-head evidence
albuterol / budesonide vs Olodaterol
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.

NCT03769090 · Phase 3 · completed
Participants were randomized and quadruple-blinded across two budesonide/albuterol groups and an active albuterol comparator, with 3,132 randomized participants. The primary clinical endpoint was met for both doses: severe exacerbations occurred in 207/1,013 versus 266/1,014 participants for high-dose treatment (hazard ratio 0.733, p<0.001) and 241/1,054 versus 276/1,056 for low-dose treatment (hazard ratio 0.835, p=0.041).

Olodaterol
Marketed by Boehringer Ingelheim
NCT00467740 · Phase 2 · completed
The study randomized 296 participants to placebo or one of four olodaterol doses, but the registry does not clearly report whether treatment assignment was blinded. Its primary outcome was a lung-function surrogate rather than a hard clinical outcome, and results were mixed across doses: only olodaterol 20 micrograms significantly improved trough FEV1 versus placebo at 4 weeks.
