Head-to-head evidence
Aclidinium bromide/formoterol fumarate vs Tiotropium bromide
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.

NCT01437397 · Phase 3 · completed
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).
Tiotropium bromide

NCT02172287 · Phase 3 · completed
This is a large, randomized, double-blind trial with both an active comparator and a placebo arm, using trough FEV1 lung function, the regulator-accepted physiological measure for COPD, as one of its primary endpoints. Registry results were not posted at the time of grading; the key result shown was recovered from the cited external source.
