Effect of Glycopyrronium on Morning Symptoms and Pulmonary Function in Patients With Moderate to Severe COPD

Randomized, multicenter, blinded, two-period cross-over design. Each treatment will last 28 days. All patients will receive both treatments in a cross-over design, with a wash-out period of 14-19 days in between. The total duration of the study for each patient is approximately 70 days (from randomization) plus 30 days of safety follow-up.

Inclusion criteria

• Male and female adults aged ≥ 40 years.
• Co-operative outpatients with a clinical diagnosis of moderate to severe COPD confirmed by spirometry according to GOLD criteria 2013 and including all of the following: a) Current or ex-smokers who have a smoking history of at least 10 pack years (e.g.10 pack years = 1 pack /day x 10 years or ½ pack/day x 20 years). An ex-smoker may be defined as a subject who has not smoked for ≥ 6 months at Screening. b) Patients with airflow limitation indicated by a post-bronchodilator FEV1 < 80% and ≥ 40% of the predicted normal value at Visit 2 (Post- bronchodilator refers to within 10-15 min of inhalation of 400 µg (4x100 µg) of salbutamol). c) .Post-bronchodilator FEV1/FVC < 0.7 at Visit 2 (Post- bronchodilator refers to within 10-15 min of inhalation of 400 µg (4x100 µg) of salbutamol).
• Patients with a COPD Assessment Test (CAT) score ≥ 10 at Visit 2.

Exclusion criteria

• Patients who have had a COPD exacerbation requiring systemic glucocorticosteroid treatment or antibiotics and/or hospitalization in the 6 weeks prior to Visit 1. In the event of an exacerbation occurring during the Screening period (Visits 1-2), the patient must be discontinued from the study. The patient may be re-enrolled once the inclusion/exclusion criteria are met. Only one re-enrollment is allowed.
• Patients who have had a respiratory tract infection within 6 weeks prior to Visit 1. Patients who develop a respiratory tract infection between Visit 1 and Visit 2 must discontinue from the trial, but may be permitted to re-enrol at a later date once the inclusion/exclusion criteria have been met. Only one re-enrollment is allowed.
• Patients on any long-acting bronchodilator therapy. Those patients may enter the study after bronchodilator withdrawal during a 10-day wash-out period (only rescue salbutamol allowed as bronchodilator therapy during wash-out). Patients on fixed combination of long acting β2-agonists/inhaled corticosteroid (LABA/ICS) therapy before screening must be switched to the equivalent dose of ICS monotherapy and salbutamol as rescue.
• Patients receiving any other prohibited COPD-related medications specified in Table 5-1 must undergo the required wash-out period prior to Visit 2.
• Patients who have had a clinical history of asthma.
• Patients with concomitant pulmonary disease, e.g. pulmonary tuberculosis or clinically significant bronchiectasis.
• Patients with alpha-1-antitrypsin deficiency.
• Patients with contraindications for LAMA treatment including medical history of symptomatic prostatic hypertrophy, bladder neck obstruction, narrow-angle glaucoma and severe renal impairment (estimated glomerular filtration rate below 30 ml/min/1.73 m2) documented in the previous 6 months.
• Patients with a history of unstable cardiovascular disease or arrhythmias including atrial fibrillation/flutter or long QT syndrome or whose resting QTcF (calculated according to Fridericia QT correction formula preferred, but Bazett acceptable) is prolonged (≥ 450 msec for males and ≥ 460 msec for females) at screening (Visit 1) or baseline (Visit 2, baseline 1).
• Concomitant use of agents known to prolong the QT interval unless it can be permanently discontinued for the duration of study.
• Patients contraindicated for treatment with, or having a history of reactions/ hypersensitivity to any of the following inhaled drugs, drugs of a similar class or any component thereof: -anticholinergic agents - long and short acting 2 agonists -sympathomimetic amines -excipients of the trial medication (lactose monohydrate and/or magnesium estearate)
• Patients whose body mass index (BMI) is less than 15 or greater than 40 kg/m2.
• History of malignancy of any organ system (other than localized basal cell carcinoma of the skin), treated or untreated, within the past 5 years, regardless of whether there is evidence of local recurrence or metastases.
