March 13, 2020 updated by: Gilda Cennamo, Federico II University

Optical Coherence Tomography Angiography Findings After Intravitreal Ranibizumab in Patients With Coats Disease

This study evaluates the retinal and vascular features in patients affected by Coats disease under the effects of Ranibizumab intravitreal injections using optical coherence tomography and optical coherence tomography angiography

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

Coats disease is an idiopathic retinal vascular disorder, occurs in young males, and is characterized by retinal telangiactasias, numerous yellowish exudates in the subretinal space, macular edema, hemorrhages and, in advanced end-stage, by exudative retinal detachment.

Ranibizumab is a vascular endothelial growth factor antagonist represent an efficacy treatment acting on vascular hyperpermeability. The optical coherence tomography and optical coherence tomography angiography represent novel and non-invasive diagnostic techniques that allow a detailed analysis of retinal and vascular features. The study evaluates the changes in optical coherence tomography and optical coherence tomography angiography parameters at baseline and after three monthly injections of Ranibizumab in Coats disease.

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

15 years to 26 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Male

Sampling Method

Non-Probability Sample

Study Population

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

Three months
Study of retinal and vascular features in Coats disease after intravitreal injections of Ranibizumab
Time Frame: Three months

The effectiveness of Ranibizumab injections for treating Coats disease using optical coherence tomography angiography (OCTA)

The parameters analyzed by OCTA were:

retinal vessel density (%), choriocapillaris vessel density (%)
Three months

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
January 1, 2016

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
