Electro Flo 5000 and Vest Therapy (EF/Vest)

December 7, 2015 updated by: Carlos Milla, Stanford University

Comparison of the Airway Clearance Efficacy of Electro Flo 5000 and Vest Therapy in

It is the goal of the proposed study to compare the efficacy, as assessed primarily by sputum weight, of these two different devices (the Electroflo 500 and VEST therapy) for airway clearance (AC) in CF patients with mild to moderate lung disease, who have stable lung health and perform AC at home as part of their routine therapeutic regimen.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

12 years and older (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  1. Diagnosis of CF established by standard criteria (sweat chloride > 60 mmol/L and/or two alleles affected by gene mutations know to be associated with CF).
  2. Age older than 12 years.
  3. Known to consistently produce sputum.
  4. Currently on a home therapeutic regimen that includes some form of AC performed at least 2 times daily.
  5. FVC and FEV1 > 40%-predicted, and with stable lung function (no greater than a 10% variation in lung function parameters over the preceding 3 months).

Exclusion Criteria:

  1. Hospitalization for CF pulmonary complications in the 2 months preceding enrollment.
  2. Hemoptysis > 60 cc in a single episode in the 4 weeks preceding enrollment.
  3. Chronic chest pain.
  4. Participation in another interventional clinical trial in the previous 30 days. -

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Wet Sputum Weight
Time Frame: End of study visit per intervention
Sputum was collected in pre-measured cups in a blinded fashion
End of study visit per intervention
Pulmonary Function Measured as a Percent Predicted BEFORE Therapy With Either ElectroFlo 5000 / VEST.
Time Frame: End of study visit per intervention
Comparison of pulmonary function by doing spirometry testing on study patients during their Day 1 & Day 2 therapy sessions. Will also compare the results based on the therapies they receive.
End of study visit per intervention
Pulmonary Function Measured as a Percent Predicted AFTER Therapy With Either ElectroFlo 5000 / Vest.
Time Frame: End of study visit per intervention
Comparison of pulmonary function by doing spirometry testing on study patients during their Day 1 & Day 2 therapy sessions. Will also compare the results based on the therapies they receive.
End of study visit per intervention
Comfort Level After Receiving Therapy With Either ElectroFlo 5000 / Vest
Time Frame: End of study visit per intervention
Comfort assessed on a scale of 1-10 by patients after therapy after each visit (1 being most comfortable, 10 being most un-comfortable)
End of study visit per intervention

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Dry Sputum Weight
Time Frame: End of study visit per intervention
Sputum was collected in pre-measured cups in a blinded fashion, dessicated and measured dry
End of study visit per intervention

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
