The purpose of this research study is to determine the amount of medicine absorbed in the lungs following dosing via eFlow nebulizer and Seebri® Breezhaler® with and without activated charcoal in subjects with moderate to severe chronic obstructive pulmonary disease (COPD).
This is a randomized, open-label, single-dose per dosing period, five-way crossover study in subjects 40 to 70 years of age with a diagnosis of moderate to severe COPD per Global Initiative for Chronic Obstructive Lung Disease guidelines. After a subject provides consent for study participation, there will be a Screening Period lasting up to 3 weeks to determine study eligibility and to allow for appropriate washout of prohibited medications. Eligible subjects will be randomized to one of 10 treatment Sequences. There will be a minimum of a 7-day washout period between each treatment visit. At each visit, subjects will receive one dose of study medication according to the sequence assigned. Subjects with a ≥ 20% decrease in forced expiratory volume in one second (FEV1) based on review of the Visit predose value compared with the Screening value will be evaluated by the investigator for continuation in the study. Subjects taking theophylline will not be able to participate in the study.

Cmax
maximum observed concentration-Cmax is calculated from plasma concentrations analyzed from blood samples collected between 0 and 48 hr.
Time frame: Up to Week 5
Area Under the Curve From Time Zero to 24 Hours (AUC0_24)
Area under the drug concentration-time curve from time zero to 24 hours postdose pk parameteres are calculated from plasma concentration analyzed from blood samples collected between 0 and 48 hr
Time frame: Up to Week 5
Area Under the Curve From Time Zero to Infinity (AUC0_infinity)
calculated by summing AUC0-last and the AUC extrapolated from tlast to infinity: AUC0-∞ = AUC0-last+ Clast / \| λz \| Clast / \| λz \| is the extrapolated area under the curve from tlast to infinity. If this quantity is greater than 20% of AUC0-∞, then AUC0-∞ was considered to be missing. Pk parameters are calculated from plasma concentration analyzed from blood samples collected between 0 and 48 hr.
Time frame: Up to Week 5
Clearance (CL) for IV Infusion of 50 mcg of Glycopyrrolate
calculated as Dose/AUC0-inf after the IV dose administration. If AUC0-inf is missing, then CL was considered as missing. Pk parameters are calculated from plasma concentration analyzed from blood samples collected between 0 and 48 hr.
Time frame: Up to Week 5
Volume of Distribution During the Elimination Phase (Vz) for IV Infusion of 50 mcg of Glycopyrrolate

Time frame: Up to Week 5
Time of Occurrence of Cmax (Tmax) for IV Infusion of 50 mcg of Glycopyrrolate
The time 0 is based on start of the infusion. Pk parameters are calculated from plasma concentration analyzed from blood samples collected between 0 and 48 hr.
Time frame: Up to Week 5
Terminal Half Life (t1/2) for IV Infusion of 50 mcg of Glycopyrrolate
calculated as ln(2) / λz . At least 3 data points at the terminal elimination phase were required to determine t½. Pk parameters are calculated from plasma concentration analyzed from blood samples collected between 0 and 48 hr.
Time frame: Up to Week 5
