Who may be able to join
- Volunteers who meet all of the following criteria will be eligible for study participation:
- Age 40-80 years, inclusive
- Non-pregnant subjects must be either not sexually active, post-menopausal, surgically sterilized, or agree to use an appropriate "double barrier" method (such as diaphragm and condom), or must currently be using a prescribed transdermal, injection, implant, or oral contraceptive during study participation.

- Requires > 10mg per day of prednisone (or equivalent corticosteroid dose) chronically
- Concomitant presence of congestive heart failure, active coronary syndromes, or other disease that in the opinion of the investigator would increase the risk resulting from participation

- History of intolerance or hypersensitivity to hypertonic saline or short acting inhaled beta agonist
Show all 12Show fewer
- Significant broncho reactivity by examination or pulmonary function testing (PFT), that in the opinion of the investigator would increase the risk of HS use
- Radiation exposure within the 12 months prior to study participation that would cause them to exceed Federal Regulations by participating in this study
- Subjects with a positive pregnancy test
- Subjects who, in the opinion of the Principal Investigator, should not participate in the study
- Subjects may be temporarily excluded from screening should they experience a respiratory tract infection that requires treatment with antibiotics and/or steroids. They may become eligible for screening four weeks after completing their treatment providing their symptoms have resolved.

About this study
Official title: Novel Therapies for Muco-Obstructive Lung Diseases: Sustained Effects of Hypertonic Saline on Mucociliary Clearance and Clinical Tolerability in Subjects With Chronic Bronchitis
The purpose of this research study is to examine the effects of two weeks of daily dosing of inhaled salt water mist (hypertonic saline - HS) on actual measurements of mucociliary and cough clearance in patients with the chronic bronchitis type of Chronic Obstructive Pulmonary Disease (COPD.
Defective mucociliary clearance (MCC) is central to the development and/or worsening of several kinds of lung diseases, including COPD/chronic bronchitis (CB), cystic fibrosis (CF), and bronchiectasis. In each case, defective MCC leads to the development of lung infections and damage to the airways from ongoing inflammation caused by a person's inability to clear mucus from the lungs.
Read more
The investigators' previous studies have shown that the administration of inhaled HS (hypertonic saline) not only acutely accelerates MCC in CF, but also that repetitive use "resets" the baseline rate of MCC within 2 weeks. It is likely that the sustained effect of HS on MCC was responsible for the ~60% reduction in the frequency of pulmonary disease exacerbations, reduced antibiotic use and improved lung function in a long-term study of HS in CF volunteers. As a result, HS has now become a standard therapy for CF lung disease and its success raises optimism that similar benefits might occur in patients with CB.
In this study the investigators will use mildly radioactive particles, technetium bound to sulfur colloid, to measure and compare the sustained effects on mucus clearance of two weeks of daily dosing of 7% hypertonic saline versus a low salt control treatment for subjects with CB. We will also be collecting sputum and breath condensation to analyze for protein and inflammatory changes that might occur with exacerbations.
Our long term goals are to improve our understanding of MCC in health and disease and to develop better therapies that support and/or restore MCC in patients with these diseases to reduce lung infections.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Inhaled 7% HS (NaCl) home treatmentOther
Administering inhaled 7% NaCl for two weeks of home treatment vs. a placebo of 0.12% NaCL during a separate home treatment period, and assessing the effects of each primarily by MCC study.
| Study group | Role | What they receive |
|---|---|---|
| AB: 7% HS home tx, then 0.12% NaCl | Placebo comparator | Inhaled Inhaled 7% HS (hypertonic saline) home treatment' , then 0.12% sodium chloride solution home treatment.
The intervention consists of the subject receiving both concentrations of inhaled sodium chloride solution, each during a different home treatment periods. Subjects randomized to order AB will receive inhaled 7% NaCl (sodium chloride solution) mist during the first home treatment period, then 0.12% NaCL during the second home treatment period. Receives: Other: Inhaled 7% HS (NaCl) home treatment |
| BA: 0.12% NaCl home tx, then 7% HS | Placebo comparator | Subjects randomized to order BA will receive inhaled 0.12% NaCl mist during the first home treatment period, then Inhaled 7% HS home treatment during the second home treatment period. Receives: Other: Inhaled 7% HS (NaCl) home treatment |
What is being measured
The primary outcome is the main question the study is designed to answer.
Measure and compare the sustained effects on mucus clearance of two weeks of daily dosing of hypertonic saline versus a low salt control treatment for subjects with CB.
Using a gamma camera and inhalation of technicium bound to sulfur colloid, mucus clearance can be measured. Will do this with two different types of inhaled saline.
Measured: Approximately 11 weeks
Secondary outcomes (1)
We will also be collecting sputum and breath condensation to analyze for protein and inflammatory changes that might occur with exacerbations.
Measured: Within 2 years after all data collection has ended

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 23 Jun 2017.
