April 11, 2025 updated by: Ciro Costagliola, Federico II University

Lutein by Scleral Iontophoresis in Patients With Stage 3 Age-Related Macular Degeneration

The objective of the clinical investigation is to evaluate the performance, safety and degree of tolerability resulting from the use of the iontophoresis medical device in adult subjects diagnosed with AMD stage 3 (AREDS classification) in one or both eyes.

Detailed Description

Lutein is a dietary carotenoid which, together with its isomer zeaxanthin, is the main component of the macular pigment of the retina.

Clinical studies have shown that prolonged oral lutein supplementation is safe and is associated with a reduction in the risk of progression from early to advanced stages of Age-Related Macular Degeneration (AMD). However, patient compliance, due to daily oral intake of lutein tablets for a prolonged period of life, is still limited. Additionally, an obstacle to oral supplementation is the variable absorption of lutein through the digestive route.

An iontophoresis method for conveying substances into the eye has been known for some time and already used in the treatment of keratoconus. In this case the substance conveyed is Riboflavin.

A medical device is now available with the following intended use: to combat all oxidative pathologies of the retina and macula, and in particular in the prevention of AMD and in the management of the patient during the evolution of the pathology.

The device consists of an iontophoresis system with scleral applicator and an ophthalmic liquid lutein solution, both of which have already obtained the CE mark. The system therefore includes a generator called K-IONO (CE in class IIa) and a kit called IONTORETINA, which includes a sterile 2 ml vial of lutein (CE in class IIb), the forward and return electrode . which consists of a scleral iontophoresis applicator and an ophthalmic liquid solution of lutein. The topical application of lutein has the advantage of improving the patient's compliance with lutein supplementary therapy compared to oral intake of the carotenoid; Furthermore, in situ application would allow high (therapeutic) concentrations of lutein to be reached in the macular area in a very short period of time (hours) compared to oral intake (months). Publicly available clinical data on scleral iontophoresis or lutein supplementation have not demonstrated any safety-related adverse events and at the same time have demonstrated a reduction in the cumulative risk of progression of AMD from intermediate to advanced stages of the disease.

The objective of the clinical investigation is to evaluate the performance, safety and degree of tolerability resulting from the use of the iontophoresis medical device in adult subjects diagnosed with AMD stage 3 (AREDS classification) in one or both eyes.

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

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
Time Frame
BCVA changes [Time Frame: 12 months] Changes in best distance-corrected visual acuity (BCVA) at the End of Study Visit compared to baseline.
Time Frame: 6 months
6 months

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.
Outcome Measure
Time Frame
BCVA changes [Time Frame: 3, 6 and 12 monhs] Changes in best distance-corrected visual acuity (BCVA) at scheduled controls (Visit 3, Visit 4, Visit 5, and Visit 6) compared to baseline
Time Frame: 12 months
