About this study

Official title: Evaluation of Regional Lung Deposition of Inhaled Saline Using the Trans-Nasal Pulmonary Aerosol Delivery Device in Healthy, Non-Smoking Adult Subjects

Purpose: Characterize the depositional attributes of a specialized trans-nasal aerosol delivery device in healthy people using clinical measurements of mucociliary clearance.

Procedures (methods): 14% hypertonic saline (HS) aerosol containing the radio tracer Tc99m-sulfur colloid will be delivered via the tPAD and compared to the well characterized PARI LC Star nebulizer (7% HS) using planar gamma scintigraphy (i.e. particle clearance). The fraction of sulfur colloid particles that clear over the ensuing 24 hours with each device will indicate the fraction deposited in conducting airways.

Read the detailed description

Purpose: This is an early device characterization study to define the fraction of delivered aerosol generated by a novel nebulizer (tPAD) that deposits in conducting airways.

Design: Open label, cross-over design, using a standard oral nebulizer (PARI LC Star) as a comparator. The order of visits will be randomized.

Methods: Gamma scintigraphy will be performed following use of each device on separate study visits.

Primary Outcome: Fraction of inhaled particles that clears over 24 hours.

What is being measured

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

  1. 24-hour clearance fraction

    The percentage of initially deposited aerosol particles that clear over 24 hours will be measured with gamma scintigraphy after 24 hours

    Measured: 24 hours

Secondary outcomes (1)
  1. Central:Peripheral Deposition Ratio

    The ratio of labelled particles initially deposited in the central and peripheral lung zones will be assessed to characterize aerosol targeting of the lung

    Measured: 0-4 minutes after deposition

Questions about this trial

What is this clinical trial studying?

A study testing tPAD Device and PARI LC Star Nebulizer in people with Lung Diseases, 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 5 inclusion and 13 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 3 Oct 2018. 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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

24-hour clearance fraction (time frame: 24 hours). 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 3 Oct 2018.
