Effect of BDP/Formoterol/G on Cough Efficacy in Moderate to Severe COPD Patients (EFFICACE) (EFFICACE)

EFfect of FIxed Triple Beclometasone/Formoterol/Glycopyrronium Therapy on Cough effiCAcy in Moderate to Severe Chronic Obstructive Pulmonary Disease (COPD) patiEnts: EFFICACE

This prospective, single centre, 8 weeks, open-label study is designed to evaluate in real-life the effect of triple Beclometasone/Formoterol/Glycopyrronium (BDP/F/G) therapy on cough efficacy, assessed by cough peak flow (CPF), after 8 weeks' treatment in patients with moderate to severe COPD.

The study's hypothesis is that in symptomatic moderate to severe COPD patients the administration of fixed dose combination BDP/F/G, by reducing lung hyperinflation (LH) and targeting small airways, may accordingly improve the cough efficacy. The increase in cough efficacy might in turn positively influence the quality of life of patients and underlie the prevention of acute exacerbations of COPD.

Study Overview

• Status: Not yet recruiting
• Conditions: COPD, Chronic Obstructive Pulmonary Disease

Detailed Description

The cough is a vital defensive mechanism of respiratory system. Chronic obstructive pulmonary disease (COPD) is characterised by persistent inflammation in the small airways inducing pathological changes that reduce airflow and increase gas trapping and lung hyperinflation (LH). LH in turn leads to the changes in diaphragmatic excursions: this might decrease the efficacy of cough. In moderate to severe COPD patients, the cough efficacy, expressed as cough peak flow (CPF) and cough expired volume (CEV), is significantly reduced when compared to those of controls.

A triple combination inhaler containing beclometasone dipropionate/formoterol/glycopyrronium (BDP/F/G) was developed as an extrafine formulation to enable efficient delivery of an inhaled corticosteroid (ICS) combined with a long-acting beta2 agonist (LABA) and a long-acting muscarinic antagonist (LAMA) to the small airways, improving LH and associated symptoms.

The study's hypothesis is that the administration of fixed extrafine BDP/F/G 87/5/9 µg q.d. for 8 weeks will determine an increase of CPF, CEV, lung function and quality of life in COPD patients non adequately controlled by double combination of inhaled treatment with ICS plus LABA or ICS plus LAMA or LABA plus LAMA.

CPF, CEV, residual volume (RV), inspiratory capacity (IC), total lung capacity (TLC), RV/TLC ratio, forced expiratory volume at 1st second (FEV1), forced vital capacity (FVC) and FEV1/FVC ratio will be assessed at baseline (Visit 1, V1) and after 4 weeks' treatment with BDP/F/G (Visit 2, V2). The same assessments will be performed after 4 weeks' treatment (Visit 3, V3).

The switch from the double to triple therapy will be carried out according to clinical practice and to the summary of product characteristics.

At V1, V2, and V3 dyspnoea perception, assessed by the modified Medical Research Council (mMRC) scale score and the quality of life, assessed by the COPD Assessment Test (CAT), will be recorded.

V1, V2, V3 will be performed in the morning between 8:00 and 10:00 ante meridien.

Each patient will sign an informed consent prior to initiation of any study-related procedure. The study protocol was approved by the local Hospital's Ethical Committee (approval number n. 38097; September 22, 2021) and it will be conducted according to the Good Clinical Practices and the Declaration of Helsinki.

The population will consist of 40 adult patients. Assuming a p values < 0.05, a sample size of 40 patients (34 + 15% drop outs) is required to detect difference of 0.4 L/s (liters/second) with a standard deviation (SD) of 0.69 in CPF following a 8 weeks BDP/F/G treatment, with a power of 90%. Efficacy endpoints will be analysed using the intention to treat analysis (ITT) which will comprise all patients treated for 8 weeks with BDP/F/G 87/5/9 µg q.d. at visit 3.

Data will be collected in a dedicated electronic Clinical Records Form (CRF). The database will be saved on a password-protected company Personal Computer (PC) which will be updated at each visit and used exclusively for scientific research purposes. At the time of enrollment, each patient will receive an alphanumeric code so that any information collected during the study, and in particular sensitive data, is treated in an anonymous manner. Data reporting patients' identifications will only be used to file patients and collect informed consent.
