Safety Study of Aztreonam Lysine for Inhalation (AZLI) in the Treatment of Early Bronchiolitis Obliterans Syndrome (BOS) (AZLI)
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.

EXPERIMENTAL: Aztreonam Lysine for Inhalation (AZLI)
Patients to received Aztreonam Lysine(AZLI)

The intervention will involve open label treatment with AZLI inhaled 75mg TID self-administered intermittently for 28 days on study drug and 28 days off study drug over a study period of 5 consecutive months (on/off/on/off/on AZLI)
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.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in Pulmonary Function, as Measured by Serial Forced Expiratory Volume in 1 Second (FEV1) on Spirometry
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).
|
Baseline, month 1
|
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.
|
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
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).

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
Time Frame: Baseline, 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).

Time Frame: Baseline, month 1
|
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.

Time Frame: Baseline - defined as a within 90 days of enrollment and After Treatment (5 months)
|
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).
