About this study

Official title: A Magnetic Resonance Imaging Study of Nasal Strips in Subjects With Nasal Congestion

The aim of the study is to evaluate the effect of the nasal strip (relative to the placebo strip) on the nasal passages using anatomical MRI scans and to demonstrate the effect of the strip on breathing correlated cortical activity, using interoceptive fMRI task and analysis techniques derived from physiological data collected during scanning.

Being tested

What is being measured

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

  1. Anatomical Measures : Cross Sectional Area

    Determination of cross sectional area derived from examination of the nasal passages and sinuses using T1 weighted MRI scans.

    Measured: Upto 2.5 hours

  2. Functional Brain Activity: Blood Oxygen Level Dependent- Interoceptive Attention Task

    Regional measures of functional brain activity to be derived from a breathing-related interoceptive task. This outcome measure was pre-specified to analyze effect on nasal strips on the functional brain activity without the use of nasal decongestant.

    Measured: Upto 2.5 hours

  3. Anatomical Measure: Volume (Single Volume Reading)

    Determination of single volume reading derived from examination of the nasal passages and sinuses, during the MRI.

    Measured: Upto 2.5 hours

  4. Cerebral Blood Flow (CBF)

    CBF was derived from Arterial-Spin Labelling (ASL) scans. ASL data were analysed using custom Matlab code, which fits a CBF model to the raw perfusion data, in order to derive quantitative estimates of CBF in units of ml/100g/minute. The computed CBF maps were co-registered to the subject's whole-brain T1-weighted anatomical scan (from the first scan session) in order to spatially divide the data into anatomical Regions of Interest (ROIs). The anatomical ROIs were themselves defined by nonlinear warping of a standard cytoarchitectonic atlas into the space of the subject's T1 anatomical scan, using the FMRIB Software Library tool FNIRT. CBF data were extracted for a subset of these anatomical ROIs.

    Measured: Upto 2.5 hours

  5. Anatomical Measures: Volume (Multiple Volume Reading)

    Determination of averaged volume reading during the MRI (Average of 8 sub-regions)

    Measured: Upto 2.5 hours

  6. Functional Measure: Blood Oxygen Level Dependent- Interoceptive Attention Task (Psychophysiological Interactive Analysis)

    Regional measures of functional brain activity were to be derived from a breathing-related interoceptive task.

    Measured: Upto 2.5 hours

Secondary outcomes (3)
  1. Breathing-related Cortical Activity (Blood Oxygen Level Dependent- Resting State)

    Regional measures of breathing-related cortical activity were derived by determining Functional Connectivity and Event-related percentage signal change.

    Functional connectivity analyzes of fMRI data where spontaneous (i.e. while the participant is at rest) signal changes in one brain region are regressed against other regions, to identify regions sharing similar functional properties.

    Event-related functional magnetic resonance imaging (efMRI) detects changes in the BOLD hemodynamic response to neural activity associated with certain event. In this case, the events were pre-defined by collecting additional data during the scan; participant respiration was determined using a simple pressure-sensitive respiration belt. Events time-locked to peak inspiration and expiration were defined separately, and regressed against brain activity, showing brain regions that were more or less active during each event type.

    Measured: Upto 2.5 hours

  2. Verbal Numerical Response (VNR): Change From Baseline to Immediately After Strip Application and 30 Minutes Post Application

    Participants provided their response for VNR on a scale of 0 to 10 (0 = Breathe Freely and 10 = Totally Blocked) how easy it was to breathe through nose at a given time.

    Measured: Upto 30 minutes

  3. VNR: Change From Baseline to 20 Minutes After Decongestant Administration, and Post Application of the Marketed Nasal Strip After Decongestant Administration

    Participants provided their response for VNR on a scale of 0 to 10 (0 = Breathe Freely and 10 = Totally Blocked) how easy it was to breathe through nose at a given time.

    Measured: Upto 2 hours

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Test strip and Nasal spray in people with Nasal Congestion, run by GlaxoSmithKline at 1 site in United Kingdom.

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 2 inclusion and 3 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 2 Aug 2017. 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 Kingdom. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 26 Jan 2015). 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?

Anatomical Measures : Cross Sectional Area (time frame: Upto 2.5 hours). The study lists 6 primary outcomes in all. 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 Aug 2017.
