Brief summary

Multicentre, prospective, non-randomised, single-arm, open label, mechanistic study to investigate the mechanism of action of BGF 160 on ventilation pattern complexity and variability

Interventions

DRUGTRIXEO AEROSPHERE

BGF 160 (Breztri Aerosphere™ in USA, Trixeo™ in France) Inhalation aerosol: pressurized metered dose inhaler containing a combination of budesonide (160 mcg), glycopyrrolate (9 mcg) and formoterol fumarate (4.8 mcg) as an inhalation aerosol. Oral inhalation: 2 inhalations of BGF 160 twice daily for 30 days.

Inclusion criteria

* Provision of signed informed consent prior to any study specific procedure * Female or male subjects aged 40-75 years inclusive at the time of enrolment (Visit 1) * Documented history of COPD with a post-bronchodilator FEV1/FVC \<0.70 and a post-bronchodilator 30 % \< FEV1 \<70% of predicted normal value (according to ERS 1993 reference values for spirometry ) at screening * Smoking history \> 10 pack-years * Baseline significant dyspnea with a mMRC ≥ 2

Exclusion criteria

* History or current diagnosis of asthma or ACOS (asthma-COPD overlap syndrome) * Respiratory infection or COPD exacerbation within 6 weeks (2 months if it resulted in hospitalization) prior to screening * Clinically significant or relevant cardiovascular conditions, laboratory tests, electrocardiogram (ECG) parameters: * Unstable angina/acute coronary syndrome, or Coronary Artery Bypass Grafting (CABG), Percutaneous Coronary Intervention (PCI) or myocardial infarction within the past 6 months. * Congestive heart failure New York Heart Association (NYHA) class III/IV. * Structural heart disease (hypertrophic cardiomyopathy, significant valvular disease). * Paroxysmal (within the past 6 months) or symptomatic chronic cardiac tachyarrhythmia. * Left bundle branch or high-degree AV block (second degree AV block type 2 and third degree AV block) unless the patient has a pacemaker. * Sinus node dysfunction with pauses. * Ventricular pre-excitation and/or Wolff-Parkinson-White syndrome. * QTcF interval \>470 msec (QT interval corrected using Fridericia's formula; QTcF=QT/\[RR1/3\]). * Any other ECG abnormality deemed clinically significant by the Investigator. * Bradycardia with ventricular rate \< 45 bpm. * Uncontrolled hypertension (\> 165/95 mmHg). * Clinically relevant respiratory conditions (other than COPD) * Severe renal impairment eGFR \< 30 * Hepatic impairment * Narrow-angle glaucoma that, in the opinion of the Investigator, has not been adequately treated. * Symptomatic prostatic hypertrophy or bladder neck obstruction/urinary retention that is clinically significant * Patients not able to perform IOS, spirometry, plethysmography, or VT acquisition (10 min) * Any contraindication to LABA or LAMA drugs or to Inhaled corticosteroids * Pregnancy or breastfeeding * Woman of childbearing age without effective contraception * Any type of cancer within 5 years * Patients under guardianship * Refuse or incapacity to give an informed consent * Absence of social insurance

Primary

MeasureTime frameDescription
change in ventilation pattern complexity and variabilitybetween V2 baseline (pre-treatment) and V3 peak (2 hours (+/-30minutes) post dose at one month)* Noise limit: % * Lyapounov component: bits/iteration no combination possible

Secondary

MeasureTime frameDescription
Changes in FEV1 (spirometry)between V2 base (pre-treatment) and V3 peak (2 hours (+/-30minutes) post dose
Change Plethysmographic Functional residual capacity (FRC)between V2 base (pre-treatment) and V3 peak (2 hours (+/-30minutes) post dose
Changes measurement for noise limit, respiratory frequency, volume, largest Lyapounov component, resistances at 5Hz, reactance at 5Hz, FEV1and FRC versus TDI at V3between V2 base measurement (pre-treatment) and V3 peak (2 hours (+/-30min)TDI at V3 (in term of continuous variable and in term of binary variable responder/non responder; a response is defined by a change in TDI ≥ +1 between baseline and V3)
Baseline dyspnea index ( BDI)before administration of BGF 160 (at V2 base (pre-treatment)) and after administration (at V3 peak (2 hours (+/-30minutes) at one month)
Change impulse oscillometry or forced oscillation: resistances at 5Hz, reactance at 5Hzbetween V2 base (pre-treatment) and V3 peak (2 hours (+/-30minutes) post doseresistance and reactance: kPa/L/s
Modified dyspnea profile ( MDP)before administration of BGF 160 (at V2 base (pre-treatment)) and after administration (at V3 peak (2 hours (+/-30minutes) at one month)
CAT score : COPD assessment test,before administration of BGF 160 (at V2 base (pre-treatment)) and after administration (at V3 peak (2 hours (+/-30minutes at one month)range 0 to 40, 40 meaning the worst condition
Likert scale for dyspnea and general healthbefore administration of BGF 160 (at V2 base (pre-treatment)) and after administration (at V3 peak (2 hours (+/-30minutes) at one month)Likert scale change in dyspnea : - 3 to + 3, + 3 maximal improvement, -3 maximal deterioration Likert scale change in general health : - 3 to + 3, + 3 maximal improvement, -3 maximal deterioration
