Head-to-head evidence
Glycopyrrolate/formoterol fumarate 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.

NCT03324607 · Phase 2/3 · completed
The study used a single treatment group without randomization, blinding, or a placebo or active comparator, and only 17 participants contributed to the primary imaging analysis. Its primary endpoints were surrogate MRI measures rather than established clinical outcomes, and the findings were mixed across those measures, so they provide limited evidence about Bevespi’s clinical effectiveness.
Olodaterol
Marketed by Boehringer Ingelheim
NCT00782210 · Phase 3 · completed
This was a randomized, double-blind, placebo-controlled phase 3 trial in 624 patients with COPD comparing two doses of olodaterol (5 mcg and 10 mcg once daily) against placebo. Both pre-specified co-primary endpoints—FEV1 AUC 0-3h and trough FEV1 at 12 weeks—were met for both doses, with large, statistically significant differences versus placebo (p<0.0001 for all primary comparisons). The trial was adequately powered, used a regulator-accepted lung function endpoint for COPD, and the primary results were clearly positive.
