About this study

Official title: Multicenter, Randomized, Controlled, Single-Masked, Cross-Over Clinical Trial to Evaluate Dry Eye Symptoms With Application of the Oculeve Intranasal Tear Neurostimulator During Exposure to a Controlled Adverse Environment (CAE®)

This study evaluates the safety and effectiveness of the Intranasal Tear Neurostimulator applied intranasally (active) compared with the same device applied extranasally (control) relating to symptoms of dry eye exacerbated by the Controlled Adverse Environment model.

Read the detailed description

Participants will be randomized to a single application sequence, either sequence "A" (intranasal application followed by control application) or sequence "B" (control application followed by intranasal application) using the device. Upon entering the CAE, participants will complete dry eye questionnaires every five minutes and will administer the device either intranasally or extranasally in randomized sequence when a certain level of ocular discomfort has been reached.

What participants receive

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

  • Intranasal Tear NeurostimulatorDevice

    The device delivers small electrical currents, activating nerves that stimulate the body's natural tear production system.

Study groupRoleWhat they receive
Intranasal ApplicationExperimentalIntranasal Tear Neurostimulator applied intranasally device (active), intranasal application for approximately 3 minutes on Day 0 when the participant experienced an ODS ≥ 3 at 2 or more consecutive time points in at least one eye during the CAE exposure.
Receives: Device: Intranasal Tear Neurostimulator
Extranasal ApplicationSham comparatorIntranasal Tear Neurostimulator device applied extranasally (control) for approximately 3 minutes on Day 0 when the participant experienced an ODS ≥ 3 at 2 or more consecutive time points in at least one eye during the CAE exposure.

What is being measured

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

  1. Change From Pre-Application to Post-Application in Eye Dryness Score (EDS) Using a Visual Analog Scale (VAS)

    The participant rated their eye dryness (both eyes simultaneously) at all visits and every 5 minutes during CAE exposure by placing a vertical mark on the 100 mm horizontal line to indicate the level of eye dryness. 0 corresponds to "no dryness" and 100 corresponds to "maximal dryness". A negative change from Baseline indicates improvement. A cross-over linear model was used with symptom relief as the response variable; sequence, application location, period, and the application location by period interaction as fixed effects; and participant (sequence) as a random effect.

    Measured: Pre-application to Post-application on Day 0

Secondary outcomes (1)
  1. Change From Pre-Application to Post-Application in the Ora Calibra Ocular Discomfort Scale (ODS) Score

    The participant graded their eye discomfort prior to CAE entry, during CAE exposure to threshold, then starting 1 minute after treatment application every 5 minutes in each eye separately using the Ora Calibra ODS where: 0=no discomfort to 4=constant discomfort. Data from the analysis eye was used to determine effectiveness. The analysis eye was defined as the eye that reached the threshold triggering the first application or if both eyes reach the threshold at the same time, the eye with the higher discomfort score or if both eyes are the same, the right eye was used. A negative change from Baseline indicates improvement. A cross-over linear model was used with symptom relief as the response variable; sequence, application location, period, and the application location by period interaction as fixed effects; and participant (sequence) as a random effect.

    Measured: Pre-application to Post-application on Day 0

Questions about this trial

What is this clinical trial studying?

A study testing Intranasal Tear Neurostimulator in people with Dry Eye Syndromes, run by Allergan at 3 sites 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 3 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: finished, as of the sponsor's last update on 31 Jan 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites 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. 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.

Are results available for this study?

Yes. Results are posted in the registry (first posted 31 Jan 2020). 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?

Change From Pre-Application to Post-Application in Eye Dryness Score (EDS) Using a Visual Analog Scale (VAS) (time frame: Pre-application to Post-application on Day 0). 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 31 Jan 2020.
