Anti-Vascular Endothelial Growth Factor (Anti-VEGF) Alone Versus Ozurdex Given Every 3 Months for Treatment of Persistent Diabetic Macular Edema

November 3, 2015 updated by: Raj K. Maturi, MD

A 10 Month, Single Masked, Randomized Controlled Study to Assess Anti-VEGF Alone Versus Ozurdex Given Every 3 Months for Treatment of Persistent Diabetic Macular Edema

To determine if there is visual benefit with Ozurdex treatment every three months compared to monthly anti-VEGF alone, in subjects with persistent diabetic macular edema. The investigator hypothesizes more frequent administration of Ozurdex in patients that have persistent diabetic macular edema will result in a more rapid and sustained improvement of visual acuity and/or optical coherence topography (OCT) compared to the use of anti-VEGF alone.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Statistics throughout this study referred to the number of eyes rather than the number of subjects. Subjects were allowed to have both eyes in the study provided that inclusion/exclusion criteria were met. Five subjects had both eyes in the study; 45 subjects were actually enrolled, resulting in 50 study eyes.

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Mean Visual Acuity Change
Time Frame: baseline to month 7
Visual acuity was obtained using ETDRS method and the total number of letters correct using that method was used to calculate mean visual acuity change.
baseline to month 7
Change in Optical Coherence Tomography (OCT) Central Subfield Thickness (CST) From Baseline to Month Seven
Time Frame: baseline to month seven
Optical coherence tomography (OCT) is an established medical imaging technique that uses light to capture micrometer-resolution, three-dimensional images. The image is presented in grid form which divides that retina into sections. The center most section (CST) is used for this outcome measurement.
