A Study Comparing the Effects of Trimbow to Fostair in COPD

Phase 4

Completed

• Conditions: Chronic Obstructive Pulmonary Disease (COPD)
• Interventions: Drug: Fostair pMDI; Drug: Trimbow pMDI

• Registration Number: NCT03842904
• Lead Sponsor: Medicines Evaluation Unit Ltd

Brief Summary

A randomised, open label 2-way cross-over study to compare the effects of inhaled Beclometasone/Formoterol/Glycopyrronium (TRIMBOW) pMDI to Beclometasone/Formoterol (FOSTAIR) pMDI on hyperinflation and expiratory flow limitation in moderate to severe chronic obstructive pulmonary disease (COPD).

Detailed Description

This study will investigate the contributions of extra-fine glycopyrronium and formoterol (within triple therapy) to improvements in small airway function in COPD patients. This will be achieved by recruiting patients with hyperinflation, and measuring improvements in hyperinflation and expiratory flow limitation as measurements of small airway disease.

This study will help understand the mechanisms of action of the bronchodilators within BDP/FF/GB, and potentially encourage treatment of small airway disease in COPD with extra-fine bronchodilator treatments. This trial will be conducted in compliance with the Declaration of Helsinki (1964 and amendments) current Good Clinical Practices and all other applicable laws and regulations.

Inclusion Criteria

1. Male and female adults aged 40 to 75 years with written informed consent obtained prior to any study-related procedure.

2. COPD diagnosis: Subjects with a diagnosis of moderate to severe COPD according to the GOLD 2018 COPD recommendations, with symptoms compatible with COPD for at least 1 year prior to screening.

3. Clinically stable COPD in the 6 weeks prior to screening and during the run-in period prior to randomisation.

4. Body mass index (BMI) in the range of 18.0 to 33.0 kg/m2 and with a minimum weight of 50 kg at screening.

5. Current smokers or ex-smokers with a smoking history of at least 10 pack years [pack-years = (number of cigarettes per day x number of years)/20].

7. Evidence of pre-bronchodilator hyperinflation (RV>120% predicted) at screening (V1) and baseline (V2).

8. Subject is willing and, in the opinion of the Investigator, able to change current COPD therapy as required by the protocol.

9. Subject is treated with double or triple therapy for at least 1 month prior to screening visit with either:

   1. Inhaled corticosteroids/long-acting β2-agonist, combination treatment (fixed and/or free)
   2. Inhaled corticosteroids and long-acting muscarinic antagonist
   3. inhaled corticosteroids/long-acting β2-agonist/long-acting muscarinic antagonist, combination treatment (fixed and/or free) In addition to the above subjects may be currently taking inhaled short acting β2-agonists and/or inhaled short acting anticholinergics.

10. A cooperative attitude and ability to be trained to correctly use the pMDI inhaler.

11. Compliance with inhaled Beclometasone run-in medication of between 80 to 120% at Visit 2 (baseline visit) and Visit 3 (Treatment Period 1, Day 1)

Exclusion Criteria

1. Inability to comply with study procedures, required restrictions, study treatment intake or any other reason that the Investigator considers makes the patient unsuitable to participate.

2. COPD exacerbation requiring oral steroids and/or antibiotics, in the 8 weeks prior to screening or prior to randomisation.

3. Use of antibiotics for a respiratory tract infection in the 8 weeks prior to screening or prior to randomisation.

5. Pregnant, lactating or breastfeeding women at screening, baseline or prior to randomisation. Positive urine pregnancy test at screening, baseline or prior to randomisation.

6. A history of one or more hospitalisations for COPD in the 12 months prior to screening or prior to randomisation.

7. Requires oxygen therapy, even on an occasional basis.

8. Known respiratory disorders other than COPD which may impact the efficacy or the safety of the study drug according to investigator's judgement. This can include but is not limited to known alpha-1 antitrypsin deficiency, active tuberculosis, lung cancer and bronchial carcinoma, bronchiectasis, sarcoidosis, lung fibrosis, pulmonary hypertension and interstitial lung disease.

9. An abnormal and clinically significant 12-lead ECG which may impact the safety of the patient according to investigator's judgement.

   N.B: Subject whose electrocardiogram (ECG) (12 lead) shows QTcF>450 males or QTcF> 470 ms for females at screening are not eligible.

10. Medical diagnosis of narrow-angle glaucoma, prostatic hypertrophy or bladder neck obstruction that in the opinion of the investigator would prevent use of anticholinergic agents.

11. History of hypersensitivity to anticholinergics, β2-agonist, corticosteroids or any of the excipients contained in any of the formulations used in the trial which may raise contra-indications or impact the efficacy of the study drug according to the investigator's judgement.

12. Clinically significant laboratory abnormalities at screening indicating a significant or unstable concomitant disease which may impact the efficacy of the study drug or the safety of the patient, according to investigator's judgement.

13. Subjects with a history of chronic uncontrolled disease including, but not limited to, endocrine, active hyperthyroidism, neurological, hepatic, gastrointestinal, renal, haematological, urological, immunological, or ophthalmic diseases that the Investigator believes are clinically significant.

14. Uncontrolled cardiovascular disease: arrhythmias, angina, recent or suspected myocardial infarction, congestive heart failure, a history of unstable, or uncontrolled hypertension, or has been diagnosed with hypertension in the 3 months prior to screening or randomisation.

16. Has had major surgery, (requiring general anaesthesia) in the 8 weeks prior to screening or prior to randomisation, or has planned surgery through the end of the study.

17. Previous lung resection or lung reduction surgery.

18. Participation in another clinical trial and received investigational drug within 30 days (or 5 half-lives whichever is longer). N.B.: For biologic products with slow elimination a washout of at least 6 months needs to be met prior to screening visit.
