The effect of first dose of LABA/LAMA bronchodilator (GFF) or placebo (PL) on spirometry at visit 5

	Subjects Receiving Placebo (n = 25)		Subjects Receiving GFF (n = 23)
	Predose	Postdose Change	Predose	Postdose Change
FEV1, L	1.79 ± 0.64	0.01 ± 0.10	1.64 ± 0.55	0.18 ± 0.21#
FVC, L	3.62 ± 1.14	0.03 ± 0.26	3.21 ± 0.82	0.17 ± 0.23*

Postdose change is the difference in the variables (FEV₁ and FVC) between predose and 120 min postdose of either PL or GFF at visit 5. FEV₁, forced expiratory volume in 1 s; FVC, forced vital capacity; GFF, glycopyrrolate/formoterol fumarate; LABA, long-acting beta agonists; LAMA, long-acting muscarinic antagonists.
