Aclidinium bromide/formoterol fumarate vs Glycopyrrolate/formoterol fumarate
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.

This was a large randomized, quadruple-blind, placebo- and active-controlled trial with 1,692 randomized participants, using the regulator-accepted clinical lung-function measure FEV1 as its primary endpoint. Results were mixed: the 400/12 μg combination significantly improved post-dose FEV1 versus aclidinium and trough FEV1 versus formoterol, whereas the 400/6 μg combination did not significantly improve trough FEV1 versus formoterol (p=0.133).

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.
