Study Overview
Status
Intervention / Treatment
Detailed Description
Patients with NCFBE who require regular home airway clearance therapy will be eligible to be screened for inclusion in the study.
After enrollment, baseline data including demographics, pulmonary related medical history including acute exacerbations (pulmonary-related hospitalizations, ED visits and physician office visits) will be collected Pulmonary function tests (PFTs) (spirometry), and a six-minute walk test will be completed. Quality of Life measures and inflammatory markers and will be collected.
Patients will be randomized to HFCWO or OPEP therapy. Each device will be used within the approved product labeling. These will be the primary airway clearance devices for these patients during the 12 months of the study period.
Following enrollment in the study and completion of a baseline visit, subjects will be seen for follow-up visits.
Detailed documentation of health status and medical history will be collected during the 12-month study period and/or at each study visit to document the occurrence of acute exacerbations and to determine time to first exacerbation, number of hospitalizations and hospitalization days, number of ICU admissions and ICU days, and number of outpatient visits (Physician's office visit, Urgent Care Visits, ED visits)
At 3 months, 6 months and 12 months following the baseline visit, the following tests/procedures will be performed. At each follow-up study visit:
- Acute exacerbations that occurred during the prior 3-month period will be documented/verified
- Pulmonary function will be assessed using standard spirometry to obtain FEV1, FVC and FEV1/FVC.
- 6-minute walk test will be completed to assess respiratory status and endurance
- The QoL-B quality of life survey will be conducted
- A sputum sample will be collected. Sputum samples will be transported to a central lab to test for inflammatory markers (sputum neutrophil elastase in μg/ml).
Mean adherence to the prescribed treatment regimen will be collected and assessed using the validated Modified Self-Reported Medication-Taking Scale. Adherence data in the HFCWO arm will also be collected via the VisiView patient portal.
Adherence results will be collected at the 3-month visit, 6-month visit and 12-month visits.
Any device related adverse events which occur after initial therapy with The Vest® System or Acapella therapy will be recorded.
Any equipment related complaints which occur after initial therapy with The Vest® System or Acapella therapy will be recorded.
At the end of the 12-month study period, subjects randomized to the PEP group will be given the option of receiving HFCWO therapy for a 6 month follow up period with outcomes data assessed at the 6-month time point.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: HFCWO group
Subjects in this arm of treatment will use The Vest® as their primary airway clearance modality for the duration of the study.
|
High frequency chest wall oscillation (HFCWO) therapy (also known as high-frequency chest-wall compression or HFCWC) is commonly prescribed to provide routine airway clearance in patients with bronchiectasis as well as other patients with a need for regular airway clearance therapy.
HFCWO generates high velocity expiratory airflow.
This airflow is thought to mobilize secretions by the sheer force created, effecting changes in rheology and moving mucus in a cephalad direction during the oscillation.
The Vest® Airway Clearance System, a commonly used device, generates HFCWO using an air pulse generator and an inflatable garment that delivers pressure pulses to the thorax.
These pressure pulses within the garment create HFCWO.

Active Comparator: OPEP group
Subjects in this arm of treatment will use the Acapella® as their primary airway clearance modality for the duration of the study.
|
Oscillating PEP is an airway clearance technique, where the person blows all the way out many times through a device.
These types of oscillating PEP devices work in two ways.
Firstly, they use resistance to make it more difficult during the breath out, like non-oscillating PEP devices.
Oscillating PEP devices also create vibrations when breathing out.
The vibrations move mucus from the surface of the airways.
After blowing through the device several times, the person will huff and cough to clear the mucus from the lungs.

The 6-min walk test (6 MWT) is a submaximal exercise test that entails measurement of distance walked over a span of 6 minutes.
The 6-minute walk distance (6 MWD) provides a measure for integrated global response of multiple cardiopulmonary and musculoskeletal systems involved in exercise.
It will provide information regarding functional capacity and response to therapy.
