About this study

Official title: Effect of Aclidinium Bromide/Formoterol on Nighttime Lung Function, Respiratory Mechanics and Early Morning Symptoms in Chronic Obstructive Pulmonary Disease (COPD)

A number of studies have documented poor sleep quality and troublesome symptoms (breathlessness, cough and sputum production) upon awakening in patients with COPD. However, the investigators know very little about measurements of respiratory mechanics (i.e., lung volumes, respiratory pressures, diaphragm function, etc) during sleep in these patients. The investigators also know little about how modern bronchodilator therapies, or the timing of when they are taken, affect respiratory mechanics during sleep or the severity of early morning respiratory symptoms. COPD is often treated with inhaled bronchodilator medications which are used to open up airways and make it easier for air to get in and out of the lungs. The investigators are studying the effects of a new inhaler that contains two different types of long-acting bronchodilator: formoterol [a long-acting beta2-agonist (LABA)] and aclidinium bromide [a long-acting muscarinic antagonist (LAMA) or anticholinergic]. Initial studies have shown that this combination therapy taken twice daily can improve some lung function measurements and respiratory symptoms in patients with moderate to severe COPD. There are also reports that evening administration of this medication may provide important advantages in patients with dominant nighttime and early morning symptoms. It is thought that sustained bronchodilation and lung deflation during the night may improve respiratory mechanics, diaphragmatic function, pulmonary gas exchange, sleep quality, and reduce severity of morning symptoms. This study will be the first to explore the effects of a nighttime dose of aclidinium/formoterol combination therapy on detailed measurements of respiratory mechanics and early morning symptoms in COPD. This study will also give us a better understanding of the mechanisms of early morning respiratory symptoms and their improvement with bronchodilators.

Read the detailed description

STUDY DESIGN: This will be a randomized, placebo-controlled crossover study where patients will receive an evening dose of either aclidinium/formoterol (ACL/FOR) or placebo after steady-state conditions on twice-daily ACL/FOR have been established. Patients will continue to take the same dosage of inhaled corticosteroid (ICS) as they did prior to study entry. Subjects will complete 4 visits as part of the study, with a fifth follow-up visit if required to ensure return to pre-study health status. After an initial screening visit (Visit 1) to confirm eligibility and a 1-week run-in period on stable triple therapy [long-acting beta2-agonist/inhaled corticosteroid (LABA/ICS) + long-acting muscarinic antagonist (LAMA)], subjects will complete baseline testing (Visit 2) which includes: full pulmonary function tests, sleep/symptom questionnaires, and polysomnography which will include periodic measurements of overnight spirometry (sitting and supine). Subjects will then receive 2-week treatment with twice-daily ACL/FOR and continue on the same ICS as during the baseline run-in. Once stability on treatment with ACL/FOR and ICS is established, there will be two overnight treatment visits (Visits 3 and 4), conducted 3-7 days apart to allow for return to normal sleep status between. For these visits, the evening dose of ACL/FOR versus placebo will be randomized to treatment order. Treatment visits will be similar to visit 2 but will include overnight measurements of respiratory mechanics (diaphragm electromyography and respiratory pressures). Short-acting bronchodilators will be withheld for at least 8 hours prior to visits.

SAMPLE SIZE: This is an exploratory physiological study with the primary outcome being an improvement in morning pre-dose trough inspiratory capacity (IC) by 200 ml. A sample size of 20 will provide at least 80% to detect this treatment difference based on a standard deviation (SD) of approximately 0.2 L for a response difference in trough IC (vanNoord, 2006), a two-tailed test and a p<0.05. The investigators anticipate that all patients will not consent to instrumentation; however, the investigators are hoping for n=12 with respiratory mechanical measurements. Due to the complexity of the study and its measurements, an interim analysis will be conducted after 10 subjects have been completed.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Morning trough inspiratory capacity (IC) as measured by a spirometer

    Early morning IC (~6:00am) will be measured to assess improvements in lung hyperinflation in response to the evening dose (~8:00pm) of a twice-daily bronchodilator vs. placebo.

    Measured: 10 hours after the evening dose of randomized study drug

Secondary outcomes (7)
  1. Early Morning Symptoms of COPD Instrument (EMSCI)

    Measured: Upon awakening in the morning: 10 hours after the evening dose of randomized study drug

  2. Distribution of sleep stages obtained during polysomnography

    Measured: Participants will be followed for the duration of the night after the evening dose of randomized study medication: between bedtime at 10pm and upon waking or 5:45am, whichever is sooner

  3. Changes in the forced expired volume in 1 second (FEV1) as measured by a spirometer

    Measured: Measurements will be collected at 2-hr intervals after the evening dose of randomized study medication (i.e., 2, 4, 6, 8 and 10 hrs post-dose)

  4. Changes in IC as measured by a spirometer

    Measured: Measurements will be collected at 2-hr intervals after the evening dose of randomized study medication (i.e., 2, 4, 6, 8 and 10 hrs post-dose)

  5. Morning trough functional residual capacity (FRC) as measured by body plethysmography

    For assessment of lung hyperinflation

    Measured: 10 hours after the evening dose of randomized study drug

  6. Diaphragm electromyography (EMGdi)

    A combined electrode-balloon esophageal/gastric catheter will be inserted nasally to measure EMGdi and respiratory pressures (esophageal and gastric pressures)

    Measured: Measurements will be collected at 2-hr intervals after the evening dose of randomized study medication (i.e., 2, 4, 6, 8 and 10 hrs post-dose)

  7. Transdiaphragmatic pressure (Pdi)

    A combined electrode-balloon esophageal/gastric catheter will be inserted nasally to measure EMGdi and respiratory pressures (esophageal and gastric pressures). Transdiaphragmatic pressure is calculated as the difference between esophageal pressure and gastric pressure.

    Measured: Measurements will be collected at 2-hr intervals after the evening dose of randomized study medication (i.e., 2, 4, 6, 8 and 10 hrs post-dose)

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Morning trough inspiratory capacity (IC) as measured by a spirometer (time frame: 10 hours after the evening dose of randomized study drug). It is what the study was designed to measure, not a finding.
