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.

Primary outcomes
- Change in Pulmonary Function, as Measured by Serial Forced Expiratory Volume in 1 Second (FEV1) on Spirometry — 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 — 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 — 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). - 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 and Month 5. — Baseline, month 5

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 and 5 AZLI courses and compared to study month 0 (baseline/prior to 1st dose). - 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 — 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). - 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 5. — Baseline, month 5

Scores represent Median Absolute Difference in theTotal Score. The SGRQ was completed 14-35 days after the start of month 5 AZLI courses and compared to study month 0 (baseline/prior to 1st dose).
