Brief Summary

This a 70 patient multi-site non blinded randomized control trial evaluating the use of the Vest® System for treatment of Non-Cystic Fibrosis Bronchiectasis (NCFBE) patients in the home setting. The study will assess outcomes in subjects requiring airway clearance therapy randomized to Oscillating Positive Expiratory Pressure (OPEP) therapy as the control group and High Frequency Chest Wall Oscillation (HFCWO) therapy as the intervention group

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, all subjects will be given the option of receiving HFCWO therapy for additional 6 month follow up period with outcomes data assessed at the 15-month and 18-month (from baseline visit) time points.

Primary Outcome Measures
NameTimeMethod
Frequency of acute exacerbations of bronchiectasis12 months

Acute exacerbation periods will be defined as per the European Respiratory Society consensus definition:

* A deterioration in three or more of the following key symptoms for at least 48 h:

* Cough

* Sputum volume and/or consistency

* Sputum purulence

* Breathlessness and/or exercise tolerance

* Fatigue and/or malaise;

* Hemoptysis AND

* A clinician determines that a change in bronchiectasis treatment is required

Secondary Outcome Measures
NameTimeMethod
6-minute walk test12 months

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.

Number of exacerbation related ICU admissions12 months

This is the total number of times the subject got admitted into an ICU facility due to symptoms of an acute exacerbation

Number of exacerbation related outpatient visits (Physician's office, Urgent Care Visits, ED visits)12 months

This is the total number of times the subject visited an outpatient healthcare facility due to symptoms of an acute exacerbation

Mean adherence to prescribed treatment regimen12 months

Adherence data will be collected using the Modified Self-Reported Medication Taking Scale and verified via the VisiView patient portal

Pulmonary function tests12 months

FVC, FEV1 and FEV1/FVC as indicators of pulmonary function will be assessed using standard spirometry

Quality of life measure using the Quality of Life - Bronchiectasis (QoL-B) tool12 months

The Quality of Life-Bronchiectasis (QoL-B), a self-administered, patient-reported outcome measure assessing symptoms, functioning and health-related quality of life for patients with NCFBE, contains 37 items on 8 scales (Respiratory Symptoms, Physical, Role, Emotional and Social Functioning, Vitality, Health Perceptions and Treatment Burden)

Time to first exacerbation12 months

The duration of time from initiation of therapy to occurrence of an episode of acute exacerbation of bronchiectasis

Number of exacerbation related hospitalizations12 months

This is the total number of times the subject was admitted as an inpatient due to symptoms of an acute exacerbation

Number of exacerbation related inpatient hospital days12 months

This is the total number of days the subject spent in an inpatient non-ICU setting due to symptoms of an acute exacerbation

Number of exacerbation related ICU days12 months

This is the total number of days the subject spent in an ICU due to symptoms of an acute exacerbation

Number of courses of antibiotics during episodes of acute exacerbation12 months

This is the total courses of antibiotics prescribed for acute exacerbations

Number of antibiotic use days during episodes of acute exacerbation12 months

This is the total number of days spent on antibiotics for acute exacerbations
