About this study

The purpose of this study is to compare the effect of three airway secretion clearance techniques (chest physical therapy, flutter device and high frequency chest wall oscillation) on decline in pulmonary function over a three year period in patients with cystic fibrosis.

Read the detailed description

Study Design: Randomized clinical trial with pulmonary function testing obtained every three months in each of the three treatment groups. Change in slope of FEV1 will be compared. Days of hospitalization and use of oral or IV antibiotics for respiratory tract infection, quality of life, subject satisfaction, and compliance will also be compared.

Sample Size: Enrollment will be completed after 180 subjects have been recruited. Fifteen CF centers will participate.

Subject Selection: Subjects must have the diagnosis of CF, be > 7 years of age and have an FEV1 > 45% of predicted.

Prescribed Therapy: Each subject will receive airway secretion clearance twice a day.

Outcomes: Change in slope of FEV1; days of hospitalization and use of oral or IV antibiotics for respiratory tract infection; quality of life; subject satisfaction; compliance.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • High frequency chest wall oscillationDevice

    Also called Vest

    Therapy prescribed twce daily for twenty minute sessions. High frequency chest wall oscillation (HFCWO) applies sharp compression pulses via an air-pulse generator and inflatable vest. HFCWO generates transient increases in airflow at low lung volumes, cough-like shear forces, and alterations in the consistency of secretions.

  • Oscillatory Positive Expiratory PressureDevice

    Also called Flutter Device (Scandipharm, Birmingham, AL)

    Therapy was prescribed twice daily for 20 minute sessions and included airway vibration, oscillating PEP, and forced expiratory technique (FET) with coughing.

  • PD&P: Postural drainage and percussionOther

    Also called CPT

    Each of the six positions are to be clapped or vibrated for 4 minutes. After each position the patient is to do three forced expiratory techniques (FET) and cough, continue with FET and coughing until all mobilized mucus has been cleared.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. rate of forced expiratory volume in 1 second (FEV1) decline

    Measured: 3 years

Secondary outcomes (5)
  1. time to need for intravenous (IV) antibiotics to treat pulmonary exacerbations

    Measured: 3 years

  2. use of other pulmonary therapies

    Measured: 3 years

  3. adherence to therapy

    Measured: 3 years

  4. patient satisfaction

    Measured: 3 years

  5. health-related quality of life

    Measured: 3 years

Questions about this trial

What is this clinical trial studying?

A study testing High frequency chest wall oscillation, Oscillatory Positive Expiratory Pressure and PD&P: Postural drainage and percussion in people with Cystic Fibrosis, run by University of Colorado, Denver at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 2 Oct 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was stopped early (reason given: High dropout, problems recruiting, and smaller than expected decline in FEV1.). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

rate of forced expiratory volume in 1 second (FEV1) decline (time frame: 3 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

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 2 Oct 2012; AzTrials last refreshed its copy on 7 Nov 2026.
