简要总结
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).
详细描述
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.

排除标准
- •Severe comorbidities including unstable cardiac or pulmonary disease or any other medical conditions that would, in the opinion of the Investigator, preclude the subject from safely completing the required tests or the study, or is likely to result in disease progression that would require withdrawal of the subject, included but not limited to the following:
- •Unstable ischemic heart disease (diagnosis of myocardial infarction or admission for acute coronary syndrome) within 6 months of screening.
- •Unstable cardiac arrhythmia or heart failure (change in treatment plan) within 6 months.
- •Treatment for diabetes mellitus within 6 months of screening.
- •Current evidence or history of a clinically significant abnormality of cardiac rhythm and/or conduction findings.
- •Concomitant clinically significant respiratory disease other than COPD (eg, asthma, tuberculosis, bronchiectasis, or other non-specific pulmonary disease).
- •History of malignancy of any organ system treated or untreated within the past 5 years, with the exception of localized basal cell carcinoma of the skin.
- •Recent history of COPD exacerbation requiring hospitalization or need for increased treatments for COPD within 6 weeks prior to the Screening Period.
- •Use of daily oxygen therapy > 10 hours per day.
- •Use of oral, intravenous, or intramuscular steroids within 3 months prior to the Screening Period.
- •Respiratory tract infection within 6 weeks prior to or during the Screening Period.
- •Significant blood loss (> 500 mL) or donated blood within 60 days preceding screening or plans to donate blood within 60 days after completing the study.
- •History of or clinically significant ongoing bladder outflow obstruction or history of catheterization for relief of bladder outflow obstruction within the previous 6 months.

- •Positive HbsAg, Hepatitis C antibody, or HIV 1/2 antibody test at Screening.
- •History of hypersensitivity or intolerance to aerosol medications, β2-agonists, anticholinergics, or sympathomimetic amines.
- •Significant psychiatric disease that would likely result in the subject not being able to complete the study, in the opinion of the Investigator.
- •Participation in another investigational drug study where drug was received within 30 days prior to the Screening Period, or current participation in another investigational drug trial in which study treatment is being administered, including a SUN-101 study
- •Previously received SUN-101 (active treatment; formerly known as EP-101).
- •Previously received any glycopyrrolate product within 28 days of Screening.
- •Subject is taking theophylline.

结局指标
主要结局
Area Under the Curve From Time Zero to 24 Hours (AUC0_24)
时间窗: Up to Week 5
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
Area Under the Curve From Time Zero to Infinity (AUC0_infinity)
时间窗: Up to Week 5
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.
Cmax
时间窗: Up to Week 5
maximum observed concentration-Cmax is calculated from plasma concentrations analyzed from blood samples collected between 0 and 48 hr.
