Trial summary

The purpose of the study is to assess the relationship between IOP pattern as recorded over 24 hours by using Triggerfish and quantified by acrophase scored dichotomously, and conversion to glaucoma in OHT patients (conversion status). Elevation of IOP above normal range is called "ocular hypertension" (OHT). Read more about this study

About this study

Official title: A Single-center, Open Label, Prospective Study Assessing the 24-hour IOP Patterns Using SENSIMED Triggerfish® in Ocular Hypertensive Patients Newly Converted to Glaucomatous Disease Versus Stable Ocular Hypertensive Patients

The purpose of the study is to assess the relationship between IOP pattern as recorded over 24 hours by using Triggerfish and quantified by acrophase scored dichotomously, and conversion to glaucoma in OHT patients (conversion status). Elevation of IOP above normal range is called "ocular hypertension" (OHT). In a previous study, it has been shown that OHT patients who progress to glaucoma (converters) have at baseline and prior to any conversion, IOP patterns that more closely resemble those of established early primary open-angle glaucoma (POAG) patients, while stable OHT patients (non-converters) have IOP patterns closer to those of healthy control subjects. The study has been planned to recruit at least 48 eligible patients (24 converters and 24 non-converters).

What is being measured

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

  1. Relationship Between Intraocular Pressure (IOP) Pattern as Recorded by TF, and Quantified by Acrophase Scored Dichotomously, and Conversion to Glaucoma in Ocular Hypertension (OHT) Patients (Conversion Status)

    For each subject, TF acrophase (ie. time when peak occured) was scored dichotomously (before and after 7 am) and compared between OHT converters and non converters patients.

    One subject was removed from the analysis because of invalid TF output.

    Measured: 24 hours

Secondary outcomes (2)
  1. Acrophase Scored Continuously (i.e. Actual Time of TF Peak Occurrence)

    Mean TF acrophase (ie. actual time when peak occured) was compared between OHT converters and non converters.

    One subject was removed from the analysis because of invalid TF output.

    Measured: 24 hours

  2. Amplitude of Best-fitting Cosine Curve to 24-hour TF Measurements

    This represents an estimate of the magnitude of 24-hour IOP-related variation. One subject was removed from the analysis because of invalid TF output.

    Measured: 24 hours

Questions about this trial

What is this clinical trial studying?

A study testing Sensimed Triggersfish® (TF) in people with Ocular Hypertension, run by Sensimed AG 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 12 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: stopped early, as of the sponsor's last update on 20 Oct 2020. 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 25 Sep 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?

Relationship Between Intraocular Pressure (IOP) Pattern as Recorded by TF, and Quantified by Acrophase Scored Dichotomously, and Conversion to Glaucoma in Ocular Hypertension (OHT) Patients (Conversion Status) (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 20 Oct 2020.
