About this study
Official title: Aztreonam Lysine for Inhalation (AZLI) in the Treatment of Early Bronchiolitis Obliterans Syndrome (BOS) After Lung Transplantation
This study is a pilot two- center study to determine if aztreonam lysine for inhalation AZLI can be safely and self-administered in lung transplant recipients with newly diagnosed bronchiolitis obliterans syndrome, grade 1 (BOS) and obtain pilot data regarding its effect on lung function in order to appropriately design and power a larger multicenter randomized study.
The hypothesis is that AZLI is a safe and effective treatment for declining lung function in lung transplant recipients with early stage BOS.
Read the detailed description
Lung transplantation is increasingly employed as a therapy for patients with advanced lung disease including cystic fibrosis, idiopathic pulmonary fibrosis or emphysema. Despite significant short-term improvements in life quality and measures of lung function after lung transplantation, long-term outcomes are disappointing primarily due to the development of a condition of airway fibrosis known as bronchiolitis obliterans (BO). It is hypothesized that aztreonam lysine for inhalation (AZLI) is a safe and effective treatment for declining lung function in lung transplant recipients with early stage BOS. In order to test the hypothesis, the investigators seek to establish the safety of AZLI in a two-center cohort of 30 lung transplant recipients with BOS treated intermittently for 5 consecutive study months and determine if this treatment leads to improvement or stabilization of lung function. The intervention will involve open label treatment with AZLI, in addition to usual transplant care, administered for 3 intermittent courses, 28 days each, over a 5 month study period.. Bronchoscopy, pulmonary function testing, and laboratory testing will be performed on a regular basis during study enrollment consistent with each center's usual standard clinical care. Patients will have a baseline screening visit, one month and five month study visit.. The study will take two years to complete from the start of funding. After a start-up period of 2 months, a total of 30 patients will be enrolled over 12 months across the two centers (15 patients each at DUMC and UCLA). Each enrolled patient will complete 5 months of intermittent therapy, and complete baseline, month 1 and month 5 visits. Over the next 6 months the study database will be finalized, statistical analysis will for primary and secondary outcomes will be performed leading to the generation of either a study abstract or manuscript.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change in Pulmonary Function, as Measured by Serial Forced Expiratory Volume in 1 Second (FEV1) on Spirometry
Within-subject change to absolute FEV1 month 1 vs. 0. FEV1 was measured 14-35 days after the start of months 1 AZLI courses and compared to study month 0 (baseline/prior to 1st dose).
Measured: Baseline, month 1
Change in Pulmonary Function, as Measured by Serial Forced Expiratory Volume in 1 Second (FEV1) on Spirometry
Within-subject change to absolute FEV1 month 5 vs 0.
Measured: Baseline, month 5
Change in Global Health Related Quality of Life, Measured by Serially Self-administered Short Form 36 Health Survey Questionnaire (SF-36) at Baseline (Prior to AZLI First Dose) and During AZLI Therapy at Month 1
The SF-36 is a commonly used, well validated measure of global health related quality of life. The survey was self-administered. There are 8 subscales which combine to form a Physical Component Score (PCS) and a Mental Component Score (MCS). We analyzed within subject changes to the PCS and MCS at month 1 vs. 0. MCS and PCS scores are relative to a US population mean of 50. The higher the score, the better one perceives his quality of life. A change in score of 4 points or more is considered clinically meaningful. Scores represent Median Absolute Difference. The SF-36 was completed 14-35 days after the start of months 1 AZLI courses and compared to study month 0 (baseline/prior to 1st dose).
Measured: Baseline, month 1

The SF-36 was completed 14-35 days after the start of months 1 and 5 AZLI courses and compared to study month 0 (baseline/prior to 1st dose).
Measured: Baseline, month 5
Change in Respiratory-specific Health Related Quality of Life, Measured by Serially Self Administered St. George's Respiratory Questionnaire (SGRQ) at Baseline (Prior to AZLI First Dose) and During AZLI Therapy at Month 1
The SRGQ measures activities, symptoms, and impacts of living with a pulmonary condition. We analyzed the change to the within-subject Total score month 1 vs. 0. Total score ranges from 0-100 with a smaller value representing better respiratory-specific QOL. A change in score of 4 points or more is considered clinically meaningful. Scores represent Median Absolute Difference in the Total Score. The SGRQ was completed 14-35 days after the start of months 1 AZLI courses and compared to study month 0 (baseline/prior to 1st dose).

Measured: Baseline, month 1
Secondary outcomes (4)
Change in FEV1 Off AZLI Therapy
This will be compared to study month 0 (baseline, when obtained as standard of care (SOC).
Measured: At Study Months 2 and 4
Change in HRQOL Off AZLI Therapy.
This will be compared to study month 0 (baseline), when obtained at standard of care visit (SOC)
Measured: At study months 2 or 4
Among Patients Colonized With Pseudomonas Aeruginosa, Change in Infection Burden as Measured by the Culture Final Report (0,1+, 2+, 3+, 4+) of in Pseudomonas Aeruginosa Sputum or Bronchoalveolar Fluid.
Microbiology data was collected when performed for SOC purposes on BAL or sputum samples. Baseline and 1 month value represents the culture final report value (0,1+, 2+, 3+, 4+) of Pseudomonas aeruginosa. A value of zero represents no Pseudomonas aeruginosa sputum or bronchoalveolar fluid. A value of 4 represents high amounts of Pseudomonas aeruginosa sputum or bronchoalveolar fluid.
Measured: Baseline, month 1
Bronchoalveolar Lavage Fluid (BALF) Neutrophilia After Treatment, When Performed as Part of Clinical Care (SOC).
The study team is measuring the change in neutrophils AFTER treatment. They will compare a SOC BAL taken after AZLI with the BAL taken within 90 days of AZLI initiation (pre or baseline measure). The post AZLI BAL measurement time range is 15 days after first course of AZLI up to last day of the 3rd and final course of AZLI (over a period of 5 consecutive months).
Measured: Baseline - defined as a within 90 days of enrollment and After Treatment (5 months)

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This study is a pilot two- center study to determine if aztreonam lysine for inhalation AZLI can be safely and self-administered in lung transplant recipients with newly diagnosed bronchiolitis obliterans syndrome, grade 1 (BOS) and obtain pilot data regarding its effect on lung function in order to appropriately design and power a larger multicenter randomized study.
The hypothesis is that AZLI is a safe and effective treatment for declining lung function in lung transplant recipients with early stage BOS.
Detailed description
Lung transplantation is increasingly employed as a therapy for patients with advanced lung disease including cystic fibrosis, idiopathic pulmonary fibrosis or emphysema. Despite significant short-term improvements in life quality and measures of lung function after lung transplantation, long-term outcomes are disappointing primarily due to the development of a condition of airway fibrosis known as bronchiolitis obliterans (BO). It is hypothesized that aztreonam lysine for inhalation (AZLI) is a safe and effective treatment for declining lung function in lung transplant recipients with early stage BOS. In order to test the hypothesis, the investigators seek to establish the safety of AZLI in a two-center cohort of 30 lung transplant recipients with BOS treated intermittently for 5 consecutive study months and determine if this treatment leads to improvement or stabilization of lung function. The intervention will involve open label treatment with AZLI, in addition to usual transplant care, administered for 3 intermittent courses, 28 days each, over a 5 month study period.. Bronchoscopy, pulmonary function testing, and laboratory testing will be performed on a regular basis during study enrollment consistent with each center's usual standard clinical care. Patients will have a baseline screening visit, one month and five month study visit.. The study will take two years to complete from the start of funding. After a start-up period of 2 months, a total of 30 patients will be enrolled over 12 months across the two centers (15 patients each at DUMC and UCLA). Each enrolled patient will complete 5 months of intermittent therapy, and complete baseline, month 1 and month 5 visits. Over the next 6 months the study database will be finalized, statistical analysis will for primary and secondary outcomes will be performed leading to the generation of either a study abstract or manuscript.

Time frame: Baseline, month 1
Within-subject change to absolute FEV1 month 1 vs. 0. FEV1 was measured 14-35 days after the start of months 1 AZLI courses and compared to study month 0 (baseline/prior to 1st dose).
Change in Pulmonary Function, as Measured by Serial Forced Expiratory Volume in 1 Second (FEV1) on Spirometry
Time frame: Baseline, month 5
Within-subject change to absolute FEV1 month 5 vs 0.
Change in Global Health Related Quality of Life, Measured by Serially Self-administered Short Form 36 Health Survey Questionnaire (SF-36) at Baseline (Prior to AZLI First Dose) and During AZLI Therapy at Month 1
Time frame: Baseline, month 1
The SF-36 is a commonly used, well validated measure of global health related quality of life. The survey was self-administered. There are 8 subscales which combine to form a Physical Component Score (PCS) and a Mental Component Score (MCS). We analyzed within subject changes to the PCS and MCS at month 1 vs. 0. MCS and PCS scores are relative to a US population mean of 50. The higher the score, the better one perceives his quality of life. A change in score of 4 points or more is considered clinically meaningful. Scores represent Median Absolute Difference. The SF-36 was completed 14-35 days after the start of months 1 AZLI courses and compared to study month 0 (baseline/prior to 1st dose).

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 4 inclusion and 7 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 29 Jan 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 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 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 26 Nov 2015). 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?
Change in Pulmonary Function, as Measured by Serial Forced Expiratory Volume in 1 Second (FEV1) on Spirometry (time frame: Baseline, month 1). The study lists 8 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 NCT01469364, which also lists 12 linked publications.
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 Jan 2016.
