About this study

Official title: An Open-Label, Multicenter Trial to Validate the Quality of Life Questionnaire-Bronchiectasis and to Evaluate Perception of Symptom Improvement Following One Course of Aztreonam for Inhalation Solution (AZLI) in Subjects With Bronchiectasis and Gram-negative Bacteria in the Airways

Over the 70-day study period, eligible patients visited the study clinic every 2 weeks (total of 6 visits) and received a 28-day course of aztreonam for inhalation solution (AZLI). The Quality of Life-Bronchiectasis (QOL-B) questionnaire was completed at several time points during the study, in additional to pulmonary function testing and other standard procedures.

  • AZLIDrug

    Also called Cayston®

    75 mg aztreonam for inhalation solution (AZLI), administered 3 times daily using the PARI Investigational eFlow® Nebulizer System (with a minimum of 4 hours between doses) following administration of a short-acting bronchodilator

Study groupRoleWhat they receive
AZLIExperimentalParticipants were evaluated beginning 14 days prior to starting a 28-day course of AZLI (Day 0 to Day 28), followed by post-treatment assessments every 14 days through Day 56, for a total of 70 days of participation in the study.

What is being measured

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

  1. Reliability of the Respiratory Domain of the Quality of Life Questionnaire-Bronchiectasis (QOL-B)

    Test-retest reliability is a measure of the stability or reproducibility of a measure over a period of time during which status on the underlying construct has not changed, and is measured by the intraclass correlation of scores obtained at 2 time points within that period. Test-retest reliability of respiratory symptoms was calculated for response at Day -14 and Day 0. Reliability of the participants' QOL-B responses was assessed from an Intraclass Correlation Coefficient (ICC). A score of ≥ 0.70 would indicate strong reliability.

    The QOL-B respiratory symptoms score was transformed onto a scale of 0-100, with higher scores representing a better quality of life.

    Measured: Day -14 to Day 0

  2. Convergent Validity of the Respiratory Domain of the QOL-B

    Convergent validity was assessed at Day -14 by examining the correlations between relevant QOL-B domains and other indicators of health status: a bronchiectasis severity score based on high-resolution computerised tomography (HRCT) scan results, forced expiratory volume in 1 second (FEV1) percent predicted, 6-minute walk test (6MWT) results, and St. George's Respiratory Questionnaire (SGRQ) symptoms scores. Correlations with absolute values of 0.30 to 0.50 indicated moderate evidence of convergent validity.

    Measured: Day -14

Secondary outcomes (1)
  1. Responsiveness of the Respiratory Domain of the QOL-B as Assessed by the Anchor-based Minimal Clinically Important Difference (MCID) Following Categorization of Level of Change Using the Global Rating of Change Questionnaire (GRCQ)

    The anchor-based method measured the participant's perception of change at Day 28 using the GRCQ, which assesses improving/worsening symptoms. Distribution of ratings was categorized as no change (-1 to 1), minimal change (≥ 1.1 to < 3.1 or ≤ -1.1 to > -3.1), moderate change (≥ 3.1 to < 5.1 or ≤ -3.1 to > -5.1) or large change (≥ 5.1, ≤ -5.1). The GRCQ evaluated change in respiratory symptoms on a visual analog scale from -7 (worsening) to +7 (improvement). The following algorithm was used to obtain the mean change:

    If the corresponding GRCQ score was in the "no change" group, then change from baseline QOL-B = Observed QOL-B change from baseline score; if > 1, then change from baseline QOL-B score = Observed QOL-B change from baseline score; if < -1, the change from baseline QOL-B score = (-1) * Observed QOL-B change from baseline score.

    Then the mean change from baseline of QOL-B respiratory symptoms score of the minimal change category group is the anchor-based MCID.

    Measured: Day 0 to Day 28

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing AZLI in people with Bronchiectasis, run by Gilead Sciences at 24 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 20 Mar 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 24 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 20 Mar 2014). 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?

Reliability of the Respiratory Domain of the Quality of Life Questionnaire-Bronchiectasis (QOL-B) (time frame: Day -14 to Day 0). The study lists 2 primary outcomes in all. 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 NCT00805025, 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 20 Mar 2014.
