Randomized,double-blind,multicenter,multinational,parallel-group,Phase III study to demonstrate the superiority of the triple fixed combination of beclometasone + formoterol + glycopyrrolate (BDP/FF/GB) administered via pressurised metered dose inhaler (pMDI) over the equivalent dose of Foster® (beclometasone dipropionate (BDP) / formoterol fumarate (FF), in patients diagnosed with chronic obstructive pulmonary disease (COPD) after 52 weeks of treatment.

Detailed Description

This 52-week randomised 2 parallel groups study evaluated the superiority of fixed triple therapy with Inhaled Corticosteroid (ICS) / Long-Acting β2-Agonist (LABA) / Long-Acting Muscarinic Antagonist (LAMA) compared with ICS/LABA in patients with severe to very severe diagnosed of COPD.

Patients' eligibility was checked during the screening visit including the review of medical history, spirometry assessments, routine labs, physical examination, 12-lead electrocardiogram (ECG), vital signs measurement, prior to entering a 2-week open-label run-in period with BDP/FF to establish a baseline.

After the run-in period, eligible patients were randomised, to either fixed triple therapy BDP/FF/GB or BDP/FF treatment group. During the 52-week treatment period, patients who completed the study did have 5 subsequent visits post randomisation scheduled respectively after 4, 12, 26, 40, and 52 weeks of treatment. During these visits, pre-dose and post-dose spirometry, 12-lead ECG, vital signs, and dyspnoea assessments were performed. Rescue medication use, compliance with the treatment, and EXACT-PRO questionnaire [EXAcerbations of Chronic Obstructive Pulmonary Disease Tool (EXACT): a patient-reported outcome (PRO)] were recorded daily (via an electronic diary) during the run-in and randomised treatment periods.

For pharmacovigilance purposes, adverse events (AE) were recorded from the time of patient informed consent signature until subject's study participation ended (Week 52 or early discontinuation).

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
1_Change From Baseline in Pre-dose Morning Forced Expiratory Volume in the 1st Second (FEV1) -- at Week 26
Time Frame: Baseline (Week 0), Week 26.

Changes from baseline in pre-dose morning FEV1 to visit at Week 26.

FEV1=Forced expiratory volume in the 1st second. It is the volume of air that can be forced out in one second after taking a deep breath.

Baseline (Week 0), Week 26.
2_Change From Baseline in 2-hour Post-dose FEV1 -- at Week 26
Time Frame: Baseline (Week 0) to 2-hour post-dose at Week 26.

Change from baseline in 2-hour post-dose FEV1, at Week 26.

FEV1=Forced expiratory volume in the 1st second. It is the volume of air that can be forced out in one second after taking a deep breath.

Baseline (Week 0) to 2-hour post-dose at Week 26.
3_Transition Dyspnoea Index (TDI) Focal Score -- at Week 26
Time Frame: Baseline (Week 0), Week 26.

Transition Dyspnoea Index (TDI) focal score is a symptom-based variable tool, used to assess breathlessness and the impact of intervention. BDI/TDI is a clinical rating method based on a validated tool that measures the impact of dyspnoea based on 3 domains: functional impairment, magnitude of task, and magnitude of effort. BDI focal score is the baseline value from which TDI focal score is assessed.

BDI scores range from 0 (very severe impairment) to 4 (no impairment) for each domain with the baseline focal score consisting of the sum of each domain (i.e. from 0 to 12). Change from baseline in dyspnoea severity was measured using the TDI. TDI score ranges from -3 (major deterioration) to +3 (major improvement) for each domain, with the TDI focal score consisting of the sum of each domain (i.e. from -9 to +9). A higher total score indicates improvement, while a lower or negative score indicates worsening symptoms.
