About this trial

The purpose of this single arm clinical trial is to evaluate the effects of 7% hypertonic saline (HS) delivered by nebulizer on clearance of mucus from the lungs in people with bronchiectasis (dilated airways) not due to cystic fibrosis. Mucociliary clearance (MCC) to measure the rate at which a person's lungs can clear inhaled particles will be assessed at baseline, and after acute (single dose) HS treatment, as well as after two weeks of treatment with HS.

The study has two main questions:

1. Evaluate the repeatability MCC measures in people with non-CF bronchiectasis 2. Compare MCC at baseline (before treatment with HS), after a single dose of HS (acute effect of HS), and after two weeks of treatment with HS twice a day (sustained effect of HS).

Participants will participate in up to 5 study visits if completing both Aim 1 and Aim 2: 1 screening/enrollment visit, 2 baseline visits (1 baseline visit if only participating in Aim 2), 1 visit during which first dose of HS would be administered and assessed, and 1 visit after 2 weeks of treatment with HS.
