About this study
Official title: Research Study in Patients With Persistent Macular Edema Due to Diabetic Retinopathy, Retinal Vein Occlusion, Uveitis, or Irvine-Gass Syndrome
The purpose of this clinical research study is to evaluate the safety and effectiveness of an investigational medication to treat macular edema that persists despite current treatment methods. Participants will be evaluated for improvement in vision and side effects.
Macular edema is a condition that affects the back of the eye (retina). It frequently occurs in people who have a history of diabetes, and is also associated with high blood pressure, uveitis, and previous eye surgery. The main symptom of macular edema is decreased vision, generally a blurring of central vision.
There are no direct costs to participants for assessments and treatment as defined in the study protocol. All candidates must be available for required scheduled visits during the trial's 6-month follow-up period. Although the disease called age-related macular degeneration (AMD) affects the same region of the eye as macular edema, they are not the same condition and AMD is not studied in this research trial.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.

The main symptom of macular edema is decreased vision, generally a blurring of central vision.

All candidates must be available for required scheduled visits during the trial's 6-month follow-up period. Although the disease called age-related macular degeneration (AMD) affects the same region of the eye as macular edema, they are not the same condition and AMD is not studied in this research trial.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing DEX PS DDS® in people with Diabetes and Macular Edema, run by Allergan 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?
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 30 May 2011. 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.
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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00035906, which also lists 4 linked publications.
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 30 May 2011.
