Trial summary

Cystoid macular edema (CME) is the most common cause of suboptimal post-operative visual acuity in uncomplicated cataract extractions. Over two million cataract extractions are performed each year, with a reported incidence ranging from 1.5 to 6.9%, resulting in an estimated 20,000-130,000 new cases of CME annually.

About this study

Official title: A Single-center Phase 2 Trial of Intravitreous Injections of Lucentis (Ranibizumab) in Subjects With Cystoid Macular Edema Secondary to Non-ischemic Retinopathy

Cystoid macular edema (CME) is the most common cause of suboptimal post-operative visual acuity in uncomplicated cataract extractions. Over two million cataract extractions are performed each year, with a reported incidence ranging from 1.5 to 6.9%, resulting in an estimated 20,000-130,000 new cases of CME annually. Clinical CME historically was associated with visual acuity of 20/40 or worse with fluorescein angiographic evidence of macular edema in a classic petaloid pattern. Angiographic CME physiologically signals an inflammatory process causing distortion of the outer plexiform layer, which if not resolved quickly could result in non-repairable visual loss. Topical, periocular, or intravitreal corticosteroids, despite their associated side effects, are the mainstay for pharmacologic treatment for patients with CME. Their efficacy has never been demonstrated in a randomized, controlled and blinded study.

This is an open-label, Phase II study of intravitreally administered ranibizumab in subjects with cystoid macular edema secondary to non-ischemic retinopathy, as seen following cataract surgery with intraocular lens implantation.

Read the detailed description

Vascular endothelial growth factor (VEGF) is known to be induced by hypoxia and has been implicated in the development of iris and retinal vascularization. VEGF, however, is also known to be a potent mediator of vascular permeability in other tissues and may perform this function in retina.

Immunohistochemical VEGF staining has been identified in patients with disorders such as aphakic and pseudophakic cystoid macular edema, ocular inflammatory disease and infection. VEGF was primarily localized within retinal neurons and within the retinal pigment epithelium in these cases. In addition or in association with its role of inducing neovascularization (Wet AMD and diabetic retinopathy, VEGF may contribute to the breakdown of the blood-retinal barrier in a variety of disorders.

Ranibizumab is a pan-VEGF A blocker that has been proven highly effective for the treatment of wet macular degeneration. The underlying pathophysiology of both cystoid macular edema and wet AMD is VEGF overproduction.

To date ranibizumab has been approved only for treating wet ARMD. In this study we will explore ranibizumab for the treatment of cystoid macular edema It is hypothesized that this population will show dramatic improvement as the initial cause of VEGF production can be isolated to the surgical procedure and due to the fact that the retinal pigment epithelium is healthier in this population as compared to the macular degeneration counterparts.

Questions about this trial

What is this clinical trial studying?

An observational study of Cystoid Macular Edema, run by Retina Institute of Hawaii 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 5 inclusion and 13 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: finished, as of the sponsor's last update on 28 May 2012. 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 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.

What does the primary outcome measure?

To evaluate the safety and tolerability of ranibizumab in patients with CME secondary to non-ischemic retinopathy (time frame: 2 years). 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 28 May 2012.
