Trial summary

Currently medications injected intravitreally in previously vitrectomized eyes have a very short half-life due to enhanced clearance of the drug. The use of the Ozurdex (dexamethasone) implant may allow sustained levels of steroid delivery to patients with diabetic macular edema that have undergone prior vitrectomy. Read more about this study

About this study

Official title: A Randomized, Pilot Study of the Efficacy and Safety of Ozurdex Steroid Implants in Post-Vitrectomized Eyes in Patients With Diabetic Macular Edema

Currently medications injected intravitreally in previously vitrectomized eyes have a very short half-life due to enhanced clearance of the drug. The use of the Ozurdex (dexamethasone) implant may allow sustained levels of steroid delivery to patients with diabetic macular edema that have undergone prior vitrectomy. The sustained steroid levels may lead to improved central retinal thickness measurements and improved visual acuity.

Read the detailed description

A total of 15 patients will be enrolled into the study. This is a 3 year randomized controlled study with the primary endpoint at 1 year. Secondary safety and efficacy endpoints will be evaluated in year 2 and year 3.

Patients will be randomly enrolled into 1 of 3 groups:

Group 1: Dexamethasone administered up to every 3 months Group 2: Dexamethasone administered up to every 6 months Group 3: Sham

Patients will be evaluated on a monthly basis with ETDRS visual acuity, intraocular pressure, fundus examination and OCT.

Ozurdex (dexamethasone) or Sham Procedure will be performed on Day 0. All patients will be evaluated monthly thereafter. One month following initial injection/sham, patients will be evaluated for focal or grid laser treatment if the investigator feels the patient will benefit.

Re-implantation of Ozurdex may occur at any time > 3 months following last injection in group 1 and > 6 months following last injection in group 2 if any of the following conditions are met:

  1. Increase of > 50 microns from the best previous CRT measurement
  2. Recurrence of intraretinal cystic edema
  3. Persistent intraretinal cystic edema

At 13 months, patients in the sham group will be eligible for Ozurdex implantation if initial inclusion/exclusion criteria are met. These patients would follow re-implantation guidelines of group 2 (up to every 6 months).

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?

Visual Acuity Gain (time frame: 13 months). 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 NCT01788475, which also lists 2 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 12 Mar 2020.
