Brief Summary

The objective of this clinical study was to evaluate the tolerability, safety, and efficacy of stepping up from fluticasone propionate (FP)/salmeterol (SLM) dry-powder inhaler (DPI) (SERETIDE™ DISKUS™) to extrafine beclometasone dipropionate (BDP)/formoterol fumarate (FF)/glycopyrronium bromide (GB) DPI (CHF5993) and to assess its effect on airway geometry and lung ventilation in subjects with advanced Chronic Obstructive Pulmonary Disease (COPD). Primary Objectives:

• Untrimmed siVaw for distal region at TLC - actual value for V2 pre-dose and V3 pre-dose
• Trimmed siRaw for distal region at TLC - actual value for V2 pre-dose and V3 pre-dose Secondary Objectives:
• Untrimmed siVaw for distal region at TLC and FRC - actual value for V2 pre-dose, V2 post-dose, V3 pre-dose and V3 post-dose
• Trimmed siRaw for distal region at TLC and FRC - actual value for V2 pre-dose, V2 post-dose, V3 pre-dose and V3 post-dose
• Safety assessment through the evaluation of treatment-emergent adverse events (TEAEs).

Outcome Measures

Primary Outcomes (2)

• Untrimmed Airway Volume (siVaw) for Distal Region at Total Lung Capacity (TLC) - Actual Value for V2 Pre-dose and V3 Pre-dose

  siVaw was measured using Functional Respiratory Imaging (FRI) at Total Lung Capacity (TLC). siVaw represents the 3D reconstruction and quantification of the volume of air within the segmented airway tree. Higher siVaw values indicate a reduction in airway obstruction and improved ventilation efficiency in the lungs. For patients with COPD, siVaw is typically reduced due to airway obstruction and structural changes in the lungs. The siVaw comparisons were made on 'untrimmed' airways SO that all visible generations in a given scan (from Visit 2 or 3 respectively) were used in order to capture all available volume information. The data were summarized by the descriptive statistics for actual values at each timepoint.

  V2 pre-dose (i.e. baseline, assessed at week 6 ± 2 days), V3 pre-dose (assessed at week 12 ± 2 days)

• Trimmed Airway Volume (siRaw) for Distal Region at Total Lung Capacity (TLC) - Actual Value for V2 Pre-dose and V3 Pre-dose

  siRaw was measured using Functional Respiratory Imaging (FRI) at TLC. siRaw represents the 3D reconstruction and quantification of resistance to airflow within the segmented airway tree. Lower siRaw values indicate improved airway patency, reduced airflow resistance, and enhanced ventilation efficiency in the lungs. For patients with COPD, siRaw is elevated due to airway narrowing, obstruction, and other structural changes in the lungs. The siRaw was evaluated using 'trimmed' data, meaning that only airway generations visible in both scans (i.e., the same airways) were used. The use of trimmed data in Multidetector computed tomography (MDCT) ensures that differences between scans are solely due to changes in airway calibre, not variations in the number of airway generations included in Computational Fluid Dynamics (CFD) calculations. The data were summarized by the descriptive statistics for actual values at each timepoint.

Study Arms (1)

CHF5993 DPI 100/6/12.5 μg

EXPERIMENTAL

All patients (25 subjects) received CHF5993 as follows: \- Treatment period (6 weeks): two inhalations b.i.d. of CHF5993 DPI 100/6/12.5 µg, giving a total daily dose of beclometasone dipropionate (BDP)/formoterol fumarate (FF)/glycopyrronium bromide (GB) 400/24/50 µg. After the screening visit (V1) that was to be performed 6 weeks ± 2 days before Visit 2 (V2), eligible patients were to undergo a 6-week run-in period with fluticasone dipropionate (FP)/salmeterol (SLM) DPI 500/50 µg (SERETIDE™ DISKUS™). At the end of the run-in period (V2), patients were to be switched to the treatment period with BDP/FF/GB DPI (CHF5993), as said for 6 weeks, until Visit 3 (V3).

• A current asthma diagnosis;
• Respiratory disorders other than COPD: patients with known respiratory disorders other than COPD that in the Investigator's opinion could affect efficacy and safety evaluation or place the patient at risk. This could include but was not limited to known α1-anti-trypsine deficiency, active tuberculosis, bronchiectasis, sarcoidosis, lung fibrosis, pulmonary hypertension, and interstitial lung disease;
