Study to Assess OCT: RNFL and GCL in MS Patients

May 30, 2021 updated by: Tampa Bay Uveitis Center, LLC

Prospective Cross Sectional Study To Assess The Clinical Utility of Optical Coherence Tomography to Measure Axonal Degeneration of the Optic Nerve, in a Cohort of 200 Subjects Meeting the Diagnostics Criteria of Multiple Sclerosis

The purpose of this study is to collect preliminary data on retinal nerve fiber layer and ganglion cell layer damage in multiple sclerosis (MS) patients, using optical coherence tomography (OCT). For this study the Zeiss Cirrus OCT Imaging System will be used. The same system will be used consistently for the duration of the study.

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.

Detailed Description

Hypothesis: Multiple sclerosis results in axonal degeneration which can be assessed objectively and non-invasively by serial OCT measurements of the RNFL and GCL.

This will be a prospective cross-sectional, non-interventional study; total recruitment will be 200 subjects. Recruitment will be stratified to enroll at least 50 subjects currently taking Lemtrada and 50 subjects with a documented diagnosis of ON. The study will enroll subjects primarily from practices in the Tampa Bay Area and adjacent counties. It is a planned non-interventional study; subjects will be followed by their neurologist and the study ophthalmologist and will receive standard of care. All subjects will have the ophthalmological examination and diagnostic measures, by the Principal Investigator, Dr. Grace Levy-Clarke, at Tampa Bay Uveitis Center.

Study Duration: The study duration will be 24 months, with an interim analysis at 50% recruitment status.

There are two primary aims of this longitudinal observational study:

  1. To determine whether atrophy within specific retinal layers over time is associated with clinical neurological progression of MS
  2. To determine whether an ON history affects the relationship described in aim # 1

Eye Exam: Subject will have an eye exam, including:

Visual Acuity Testing Color Vision Testing Automated perimetry/Peripheral Vision Testing Completing the National Eye Institute Visual Functioning Questionnaire (NEI/VFQ) Slit Lamp Examination Measurement of Intraocular Pressure (IOP) Dilated Fundus Examination (Ophthalmoscopy) Fundus Photography Optical Coherence Tomography: RNFL and Macular OCT

Neurologic Assessments: Must be performed no more than 60 days prior to screening/assessment Day 0 Ophthalmic Assessments

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

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
Retinal Nerve Fiber Layer measurement (RNFL: peri-papillary OCT)
Time Frame: Assessed at Baseline then 6, 12, 18 and 24-month time points
Optical Coherence Tomography (OCT) will be used to assess change in RNFL of patients with multiple sclerosis
Assessed at Baseline then 6, 12, 18 and 24-month time points

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
Measure Description
Time Frame
Ganglion Cell Layer measurement (GCL: Macular OCT)
Time Frame: Assessed at Baseline then 6, 12, 18 and 24 - month time points
Optical Coherence Tomography (OCT) will be used to assess change in GCL of patients with multiple sclerosis
Assessed at Baseline then 6, 12, 18 and 24 - month time points

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.
