What is being measured

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

  1. Change From Baseline in Central Retinal Thickness in the Study Eye

    Central retinal thickness is assessed in the study eye by Optical Coherence Tomography (OCT). OCT is a laser-based, noninvasive, diagnostic system that provides high-resolution, three-dimensional images of the retina from which retinal thickness can be measured. A negative change from baseline in retinal thickness indicates an improvement and a positive change from baseline indicates a worsening.

    Measured: Baseline, Week 26

Secondary outcomes (3)
  1. Change From Baseline in Best Corrected Visual Acuity (BCVA) in the Study Eye

    BCVA is measured in the study eye using an eye chart and is reported as the number of letters read correctly (ranging from 0 to 100 letters). The lower the number of letters read correctly on the eye chart, the worse the vision (or visual acuity). An increase from baseline in the number of letters read correctly indicates improvement and a decrease from baseline in the number of letters read correctly indicates a worsening.

    Measured: Baseline, Week 26

  2. Percentage of Patients With at Least 10 Letters of Improvement in BCVA From Baseline in the Study Eye

    BCVA is measured in the study eye using an eye chart and is reported as the number of letters read correctly (ranging from 0 to 100 letters). The lower the number of letters read correctly on the eye chart, the worse the vision (or visual acuity). An increase in the number of letters read correctly indicates improvement and a decrease in the number of letters read correctly indicates a worsening.

    Measured: Baseline, Week 26

  3. Percentage of Patients With Fluorescein Leakage as Measured by Fluorescein Angiography (FA) in the Study Eye

    Fluorescein leakage is measured in the study eye by FA. FA is a technique for examining the circulation of the retina (and detecting any leakage) using a dye-tracing method. The assessment of fluorescein leakage compared to baseline is categorized as Improved (leakage area decreased ≥ 10%), Unchanged (leakage area changed < 10%), and Worsened (leakage area increased ≥ 10%).

    Measured: Baseline, Week 26

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Dexamethasone in people with Diabetic Macular Edema and Vitrectomy, run by Allergan at 2 sites in 2 countries.

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 4 inclusion and 7 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 23 Apr 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States, Australia. 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 4 Aug 2014). 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 in Central Retinal Thickness in the Study Eye (time frame: Baseline, Week 26). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00799227, which also lists 1 linked publication.

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 23 Apr 2019.
