About this study

Official title: Zeaxanthin as an Adjuvant to Combination Therapy for Treatment of Choroidal Neovascularization (CNV) in Exudative Age Related Macular Degeneration (ARMD)

The purpose of this study is to evaluate the fact that 20 milligrams per day of oral Zeaxanthin as a supplement to patients with Choroidal neovascularization (CNV) and exudative age related macular degeneration (ARMD) undergoing combination therapy with intravitreal Bevacizumab (Avastin), intravitreal Dexamethasone and PDT laser photocoagulation and improves anatomic and visual outcome compared to patients not receiving oral Zeaxanthin. Study patients will be taking AREDS(PreserVision) and multivitamins (Centrum Silver); in addition one-half of the patients will receive 20mg of oral Zeaxanthin.

Read the detailed description

One of the current treatments for choroidal neovascularization in exudative age related macular degeneration (ARMD) involves a combination of laser photocoagulation (PDT) and injections of an anti-inflammatory (Dexamethasone) and an anti-angiogenic (Bevacizumab). This combination therapy is designed to stabilize vision, improve vision in selected cases and reduce the total number of treatment cycles overall compared to other methods of treatment presently in use. Many retinal physicians are treating exudative ARMD with an ocular injection every 4 weeks for a number of years. Combination therapy has reduced the number of treatment cycles to less than 3 for many patients; and in preliminary studies, patients taking 20 milligrams of dietary oral zeaxanthin required even less treatment cycles to achieve stability. In this trial, the only variable will be the oral consumption of 20 milligrams of zeaxanthin daily taken in half of the patients randomized to this group. The remaining half patients with still undergo combination therapy, but without taking 20 milligrams of oral dietary Zeaxanthin.

Zeazanthin is found in many foods and low doses of zeazanthin are commonly added to many multivitamins already on the market. All products with Zeazanthin is a constituent, including EyePromise Ten, have excellent safety profiles and no side effects or adverse events have been reported thus far with this supplement.

Zeazanthin is in many eye supplements and is being studied by the NEI, National Eye Institute, as part of the AREDS-2 study looking at the benefits of Lutein, Zeazanthin and Omega 3 Fish Oils on AMD progression. The patients will be taking 20 milligrams a day of Zeazanthin. The United States and global safety organization have established an ADI (acceptable daily intake) of 2 mg/kg body weight/day of Zeazanthin. This equates to 155 mg per day for 177 pound person.

Millions of doses of EyePromise Ten have been taken without side effects. The new part of this trial, again is taking 20 milligrams of Zeazanthin while being combined with medical injections and laser treatments. Zeazanthin is one of the two pigments obtained from the diet that deposit in the macula and give it the yellow color. While obtained from the diet the retina accumulates it up to 1000 times higher levels than anywhere else in the body. Numerous scientific and clinical trials suggest that it is critical to the protection of the retina and in reducing risks and progression of age related macular degeneration.

Questions about this trial

What is this clinical trial studying?

An observational study of Exudative Age-Related Macular Degeneration, run by The Retina Center of St. Louis County, PC 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 7 inclusion and 7 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 6 Apr 2016. 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?

BEST CORRECTED VISUAL ACUITY AFTER TREATMENTS (time frame: 3, 6 12, 15, 18 AND 24 MONTHS AFTER ENTRY). 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 NCT01527435, which also lists 1 linked publication.

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 6 Apr 2016.
