Research Study in Patients With Persistent Macular Edema

A Phase 2 interventional study of DEX PS DDS® in Diabetes, Macular Edema and Diabetic Retinopathy, sponsored by Allergan. Completed at 1 site in United States. Open to participants aged 12 Years and older. Per ClinicalTrials.gov, last updated 2011-05-30.

Why
  1. The study's listed conditions name Diabetic Retinopathy, a narrower term within Diabetes Mellitus.
Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

Study summary

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.

In context

Diabetic Retinopathy Reclassified

778 studies on the registry are indexed under Diabetic Retinopathy; 142 are open to participants now.

This study's enrollment of 315 is above the median of 80 across 481 interventional studies indexed under Diabetic Retinopathy.

Lead sponsor

Allergan is the lead sponsor of 505 studies on the registry; none are open to participants now.

Of its 93 completed or terminated interventional studies of FDA-regulated products, 91 (98%) have results posted.

First submitted before Allergan became part of AbbVie.

Compared within Diabetic Retinopathy, this study's primary condition as ClinicalTrials.gg classifies it; the registry's first condition term is Diabetes Mellitus. The counts are of registry records indexed under each term, refreshed daily. How we classify →

Eligibility criteria

Inclusion: Persistent macular edema associated with diabetic retinopathy, uveitis, retinal vein occlusion, or Irvine-Gass syndrome, persisting at least 90 days after laser treatment or medical management by a physician.

Exclusion: Females who are pregnant or lactating, and females of not using adequate for the duration of the study. Any intraocular procedures or laser treatment less than 90 days before enrollment.

Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
