Lutein Influence on Macula of Persons Issued From Amd Parents (LIMPIA)

May 17, 2013 updated by: University Hospital, Bordeaux
Age-related macular degeneration (AMD) is a degenerative disease of the centre of the retina (named macula) and is the leading cause of blindness in industrialized countries. There is growing interest in the potential preventive role of two carotenoids (lutein and zeaxanthin) of dietary origin, which specifically accumulate in the macula, where they form the macular pigment. A first step towards the demonstration of a preventive effect of macular pigment for AMD consists in the evaluation of the effect of lutein and zeaxanthin supplementation on their plasma and retinal concentrations.

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

The objective of this study is to estimate the efficiency of a nutritonal supplementation with lutein and zeaxanthin to increase their plasma concentration and the density of macular pigment, in subjects at high genetic risk for AMD (1st generation stemming from parent affected by DMLA). This study is a multicentric, double blind, randomized clinical trial of supplementation versus placebo

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

36 years to 66 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

  • The presence of a AMD in one eye is possible
  • Enlightened consent writes, dated and signed by the participant and the investigator above all examination required by the research.

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
The main assessment criterion is the measure of the evolution of the density of the macular pigment after 6 months of supplementation
Time Frame: 6 months after stop of the supplementation
Difference in measures of the density of the macular pigment at baseline and 6 months after stop of the supplementation
6 months after stop of the supplementation

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
