About this study

Official title: Intravitreal Dexamethasone Implant for Persistent Macular Thickening and Edema After Vitrectomy for Epiretinal Membrane: A Pilot Study

This study seeks to evaluate the effect of the intravitreal 0.7mg dexamethasone implant on central macular thickness and visual acuity in those patients with persistent macular edema after pars plana vitrectomy for epiretinal membrane.

Read the detailed description

Macular edema is a relatively common occurrence after pars plana vitrectomy. Kim et al described that 47% of eyes undergoing vitrectomy for epiretinal membrane, macular hole, or vitreous hemorrhage had evidence of macular thickening on optical coherence tomography scan.1 Post-vitrectomy macular edema can limit potential visual acuity gain from removal of a symptomatic epiretinal membrane. Typical treatment of post-operative macular edema consists of topical non-steroidal anti-inflammatory drugs (NSAIDs) and topical corticosteroids; however, there are still resistant cases with refractory macular thickening.

The dexamethasone intravitreal implant (Ozurdex; Allergan, Irvine, CA) is currently FDA-approved for the treatment of posterior uveitis as well as macular edema secondary to retinal vein occlusion and diabetic retinopathy. Furino et al reported a retrospective series describing how a single injection of the 0.7mg dexamethasone intravitreal implant resulted in a substantial increase in best-corrected visual acuity (BCVA) and a decrease in central macular thickness (CMT) on spectral-domain optical coherence tomography (SD-OCT) in 8 patients with persistent macular thickening after pars plana vitrectomy for epiretinal membrane. There has been no prospective study evaluating the efficacy of this pharmacologic agent in this setting.

As such, the purpose of this study is to prospectively evaluate the effect of the intravitreal 0.7mg dexamethasone implant on CMT and BCVA in those patients with persistent macular edema after pars plana vitrectomy for epiretinal membrane.

The results of this study will help delineate whether the intravitreal dexamethasone implant has efficacy in improving CMT and/or visual acuity in those patients with refractory macular thickening after pars plana vitrectomy for epiretinal membrane.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • DexamethasoneDrug

    Also called Ozurdex

    • On study visit #1 all patients will have a SD-OCT scan and measurement of baseline visual acuity. All patients will receive the 0.7mg dexamethasone intravitreal implant
    • Subsequent follow-up visits will be at 1 month, 2 months, 3 months, 4 months, 5 months, and 6 months after intravitreal injection of dexamethasone implant
    • Each visit will consist of measurement of visual acuity, intraocular pressure, dilated fundoscopic examination, and SD-OCT scan
    • Anticipated duration of the study: 6 months

What is being measured

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

  1. Mean central macular thickness (CMT) on SD-OCT at 1 month, 3 months, and 6 months after intravitreal injection of dexamethasone implant

    Measured: Change in mean macular thickness baseline at 6 months

Secondary outcomes (1)
  1. Visual acuity

    Measured: Change in visual acuity baseline at 6 months

Questions about this trial

What is this clinical trial studying?

A study testing Dexamethasone in people with Macular Edema and Epiretinal Membrane, run by Wills Eye 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?

The sponsor lists 8 inclusion and 8 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: stopped early, as of the sponsor's last update on 3 Oct 2018. 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.

Are results available for this study?

The study was stopped early (reason given: Terminated due to lack of drug efficacy. 2017 study did not show benefit.). Results are not available in the source record.

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?

Mean central macular thickness (CMT) on SD-OCT at 1 month, 3 months, and 6 months after intravitreal injection of dexamethasone implant (time frame: Change in mean macular thickness baseline at 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 3 Oct 2018.
