NCT00817180

  Purpose

This study is a preliminary study designed to determine the safety and effectiveness of HFCWO using the InCourage vest system as an airway clearance technique for the treatment of CF. The study will compare HFCWO to the most commonly used airway clearance technique in Canada, namely the Positive Expiratory Pressure technique in patients with CF over a period of one year. As this is a preliminary study, it will not be able to determine if the vest is equivelant to PEP, but will provide the information needed to plan a larger study to answer that question.

Primary Outcome Measures:
  • Difference in the number of respiratory exacerbations during the 1 year study period [ Time Frame: 1 year ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • The time to the first respiratory exacerbation. Change in FEV1 measured as difference in the yearly mean rate of decline. Cost analysis between the two groups. Quality of life questionnaire. Patient satisfaction questionnaire and Adherence to treatment. [ Time Frame: 1 year ] [ Designated as safety issue: No ]

  • Confirmed diagnosis of CF.
  • FEV1> 45% predicted as calculated by Wang reference equations
  • Written informed consent (and assent when applicable) obtained from subject or subject's legal representative and ability for subject to comply with the requirements of the study.
  • Clinically stable at enrollment with no evidence of respiratory exacerbation within a month of enrollment as assessed by the site CF Physician.
  • Willingness to adhere to prescribed treatment regimen.

Exclusion Criteria:

  • Diagnosis of Allergic Broncho-Pulmonary Aspergillosis, or a persistent culture for B.cepacia complex within the previous 1 year period
  • .On active treatment for non Tuberculous Mycobacterium.
  • Use of intravenous antibiotics within the previous 14 days of enrollment.
  • Initiation and or change in maintenance therapy within 14 days of enrollment.

  • Concurrent participation in another study that could potentially affect the present study.
  • Haemoptysis of over 20 mls on more than 2 occasions within the previous 30 days from enrollment.
  • A pneumothorax in the six months preceding the study.
  • Presence of a condition or abnormality that in the opinion of the site CF Physician would compromise the safety of the patient or the quality of the data.
