About this study

Official title: A Single Center, Open Label, Prospective Study Measuring Proportion of Patients With Suboptimal Peak Inspiratory Flow Rate (sPIFR) Over 24 Weeks in an Ambulatory Setting Among Moderate to Very Severe COPD Patients

Recent studies have reported that some Chronic Obstructive Pulmonary Disease (COPD) patients may have a suboptimal ability to generate a sufficient inspiratory effort to achieve adequate lung delivery of inhaled medications through dry powder inhalers. Sparse data is available about the inspiratory capacity of these patients in the home setting, whether clinically stable or when experiencing worsened respiratory symptoms outside the acute care setting. This study is undertaken to better understand the proportion of patients with suboptimal peak inspiratory flow rate (sPIFR) measurements amongst COPD patients receiving dry powder inhaler(s) (DPI) in the ambulatory setting. Further, the study will characterize PIFR over time, the variability of PIFR measurements, and the associations with potential predictors (demographics, clinical, Patient-Reported Outcomes (PRO), body position, and device) as well as exacerbations frequency and change in PIFR around period of exacerbation.

To complete these aims, 120 participants will be enrolled in a 6 month study to perform PIFR measurements and respiratory questionnaires at home.

What participants receive

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

  • Home PIFR monitoring with InCheck DialDevice

    The In-Check G16 DIAL® (Alliance Tech Medical, Granbury TX) is a simple hand-held device that measures PIFR via a brief inspiratory maneuver.

What is being measured

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

  1. Occurrence of Suboptimal PIFR

    The occurrence of suboptimal Peak Inspiratory Flow Rate (sPIFR) over 24 weeks. sPIFR will be defined as any two consecutive measurements on different days below the optimal threshold for any prescribed DPI (e.g.,<30 L/min for Handihaler® (High resistance DPI), <60 L/min for Ellipta® (Medium resistance DPI))

    Measured: 24 weeks

Questions about this trial

What is this clinical trial studying?

A study testing Home PIFR monitoring with InCheck Dial in people with COPD, run by University of North Carolina, Chapel Hill 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 8 inclusion and 7 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: finished, as of the sponsor's last update on 21 Sep 2022. 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?

Yes. Results are posted in the registry (first posted 21 Sep 2022). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Occurrence of Suboptimal PIFR (time frame: 24 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04168775, which also lists 2 linked publications.

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 21 Sep 2022.
