What is being measured

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

  1. Change From Baseline Mean Diurnal Intraocular Pressure (IOP) in the Study Eye on Day 28

    Intraocular pressure (IOP) was measured using a Goldmann applanation tonometer. Diurnal IOP, defined as the mean IOP over the day based on values obtained at 8 AM, 10 AM, 1 PM, and 4 PM, was calculated for each visit. Both eyes were tested, with the right eye preceding the left eye. The operator initially set the dial at 10 mmHg, then looked through the slit lamp and adjusted the dial to take the reading, and then recorded the results. The procedure was repeated on the same eye twice consecutively. If the measurements were within 2 mmHg or less of each other, the mean of the 2 readings was recorded as the IOP at that time point. If the 2 readings were more than 2 mmHg of each other, a third (consecutive) reading was taken and the median (middle) IOP was recorded as the IOP at that time point.

    Measured: Baseline, 28 days

Secondary outcomes (2)
  1. Change From Baseline in Mean Intraocular Pressure (IOP) at Specific Time Points on Day 14 and Day 28

    Intraocular pressure (IOP) was measured using a Goldmann applanation tonometer. Both eyes were tested, with the right eye preceding the left eye. The operator initially set the dial at 10 mmHg, then looked through the slit lamp and adjusted the dial to take the reading, and then recorded the results. The procedure was repeated on the same eye twice consecutively. If the measurements were within 2 mmHg or less of each other, the mean of the 2 readings was recorded as the IOP at that time point. If the 2 readings were more than 2 mmHg of each other, a third (consecutive) reading was taken and the median (middle) IOP was recorded as the IOP at that time point.

    Measured: Baseline, Day 14, Day 28

  2. Target IOP

    Percentage of participants with IOP of 18 mmHg or Lower, 16 mmHg or Lower, or 14 mmHg or Lower at Any Visit Through Day 28. Intraocular pressure (IOP) was measured using a Goldmann applanation tonometer. Both eyes were tested, with the right eye preceding the left eye. The operator initially set the dial at 10 mmHg, then looked through the slit lamp and adjusted the dial to take the reading, and then recorded the results. The procedure was repeated on the same eye twice consecutively. If the measurements were within 2 mmHg or less of each other, the mean of the 2 readings was recorded as the IOP at that time point. If the 2 readings were more than 2 mmHg of each other, a third (consecutive) reading was taken and the median (middle) IOP was recorded as the IOP at that time point.

    Measured: Up to 28 days

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing PF-03187207 and Latanoprost 0.005% in people with Primary Open Angle Glaucoma and Ocular Hypertension, run by Bausch & Lomb Incorporated at 13 sites in Japan.

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 14 Sep 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 13 sites in Japan. 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.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 27 Aug 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 Baseline Mean Diurnal Intraocular Pressure (IOP) in the Study Eye on Day 28 (time frame: Baseline, 28 days). 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 14 Sep 2020.
