What is being measured

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

  1. Mean Change From Baseline in Post-dose Trough FEV1

    Mean change from baseline in post-dose trough forced expiratory volume in 1 second (FEV1) following 26 weeks of treatment. Trough FEV1 is defined as the mean of the two FEV1 values measured at 23 hr 15 min and 23 hr 45 min after the morning dose taken at site on Day 181. Baseline FEV1 is defined as the average of the pre-dose FEV1 measured at -45 min and -15 min at Day 1.

    Measured: Baseline, 26 weeks

Secondary outcomes (10)
  1. Annualized Rate of Moderate or Severe COPD Exacerbations

    Moderate or severe COPD exacerbations starting between first dose and one day after last treatment are included. COPD exacerbations that occurred within 7 days of each other are collapsed as one event.

    Measured: 26 weeks

  2. Annualized Rate of COPD Exacerbations Requiring Treatment With Systemic Glucocorticosteroids and/or Antibiotics, Moderate Exacerbations Only

    COPD exacerbations starting between first dose and one day after last treatment are included. COPD exacerbations that occurred within 7 days of each other are collapsed as one event

    Measured: 26 weeks

  3. Annualized Rate of COPD Exacerbations Requiring Hospitalisation

    COPD exacerbations starting between first dose and one day after last treatment are included. COPD exacerbations that occurred within 7 days of each other are collapsed as one event.

    Measured: 26 weeks

  4. Mean Change From Baseline in Pre-dose Trough FEV1

    Trough FEV1 is defined as the average of the pre-dose FEV1 measurements at -45 min and -15 min prior to dosing at each visit except Day 182 which is the average of the post-dose FEV1 measurements at 23h15min and 23h45min after dosing at Day 181. Baseline FEV1 is considered the Day 1 average of pre-dose measurements.

    Measured: 26 weeks

  5. Mean Change From Baseline in St. George's Respiratory Questionnaire

    The St. George Respiratory Questionnaire C (SGRQ-C) is used to provide the health status measurements in this study. Baseline SGRQ-C is defined as the assessment taken right before the first dose of the double-blind drug on Day 1. Higher values correspond to greater impairment of health status. The SGRQ contains 50 items divided into 2 parts covering 3 aspects of health related to COPD: Part I covers "Symptoms" and is concerned with respiratory symptoms, their frequency and severity; Part II covers "Activity" and is concerned with activities that cause or are limited by breathlessness; Part II is also concerned with "Impacts", which covers a range of aspects concerned with social functioning and psychological disturbances resulting from airways disease. A score was calculated for each of these 3 subscales and a "Total" score was calculated. In each case the lowest possible value is zero and the highest 100. Higher values correspond to greater impairment of health status.

    Measured: Baseline, 12 weeks

  6. Mean Change From Baseline in St. George's Respiratory Questionnaire

    The St. George Respiratory Questionnaire C (SGRQ-C) is used to provide the health status measurements in this study. Baseline SGRQ-C is defined as the assessment taken right before the first dose of the double-blind drug on Day 1. Higher values correspond to greater impairment of health status. The SGRQ contains 50 items divided into 2 parts covering 3 aspects of health related to COPD: Part I covers "Symptoms" and is concerned with respiratory symptoms, their frequency and severity; Part II covers "Activity" and is concerned with activities that cause or are limited by breathlessness; Part II is also concerned with "Impacts", which covers a range of aspects concerned with social functioning and psychological disturbances resulting from airways disease. A score was calculated for each of these 3 subscales and a "Total" score was calculated. In each case the lowest possible value is zero and the highest 100. Higher values correspond to greater impairment of health status.

    Measured: Baseline, 26 weeks

  7. Transition Dyspnea Index (TDI) Score

    Transitional Dyspnea Index (TDI) score presents the degree of impairment due to dyspnea. The lower the score the worse the severity of dyspnea. The Baseline Dyspnea Index (BDI) / TDI is an instrument used to assess a participant's level of dyspnea. The BDI and TDI each have three domains: functional impairment, magnitude of task and magnitude of effort. BDI domains were rated from 0 (severe) to 4 (unimpaired) and rates summed for baseline focal score ranged from 0 to 12; lower scores mean worse severity. TDI domains were rated from -3 (major deterioration) to 3 (major improvement) and rates summed for transition focal score ranged from -9 to 9; negative scores indicate deterioration. A TDI focal score of ≥1 was defined as a clinically important improvement from baseline.

    Measured: 12 weeks

  8. Transition Dyspnea Index (TDI) Score

    Transitional Dyspnea Index (TDI) score presents the degree of impairment due to dyspnea. The lower the score the worse the severity of dyspnea. The Baseline Dyspnea Index (BDI) / TDI is an instrument used to assess a participant's level of dyspnea. The BDI and TDI each have three domains: functional impairment, magnitude of task and magnitude of effort. BDI domains were rated from 0 (severe) to 4 (unimpaired) and rates summed for baseline focal score ranged from 0 to 12; lower scores mean worse severity. TDI domains were rated from -3 (major deterioration) to 3 (major improvement) and rates summed for transition focal score ranged from -9 to 9; negative scores indicate deterioration. A TDI focal score of ≥1 was defined as a clinically important improvement from baseline.

    Measured: 26 weeks

  9. Change From Baseline in the Mean Daily Number of Puffs of Rescue Medication

    Change from baseline in mean daily number of puffs of rescue medication (number of puffs taken in the previous 12 hours) over 26 weeks of treatment.

    Measured: Baseline, 26 weeks

  10. Mean Change From Baseline in Forced Vital Capacity (FVC)

    Change from baseline in forced vital capacity following 26 weeks of treatment. Trough FVC is defined as the average of the pre-dose FVC measurements at -45 min and -15 min prior to dosing at each visit except Day 182 which is the average of the post-dose FVC measurements at 23h15min and 23h45min after dosing at Day 181. Baseline is considered the Day 1 average of pre-dose measurements.

    Measured: Baseline, 26 weeks

They depend on the study and the treatment, and no study can promise a benefit. 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?

Yes. Results are posted in the registry (first posted 29 Apr 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Mean Change From Baseline in Post-dose Trough FEV1 (time frame: Baseline, 26 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02603393, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Apr 2019.
