Centralized Reading Assessment of Chronic CerebroSpinal Venous Insufficiency (CCSVI) in Patients With Multiple Sclerosis and Other Neurological Diseases

February 11, 2016 updated by: Robert Zivadinov, MD, PhD, University at Buffalo

Prevalence of Chronic Cerebrospinal Venous Insufficiency in Patients With Multiple Sclerosis and Other Neurological Diseases. An Ultrasound, Blinded, Case-Controlled, Centralized Reading Assessment

This a retrospective, blinded trial in which collaborators in Italy will review the doppler findings from the Combined Transcranial and Extracranial Venous Doppler (CTEVD) trial in an attempt to measure reproducibility.

Study Overview

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.

Detailed Description

This study will retrospectively investigate doppler images from the second phase of the CTEVD trial.

  1. To determine the prevalence of CCSVI in patients with MS, compared with the prevalence observed in a control population consisting of Other Neurological Diseases (OND) patients and Healthy Controls (HC) by using blinded, controlled centralized ultrasound reading assessment of 5 Venous Haemodynamic (VH) CCSVI CCSVI Doppler UltraSound (CDUS) criteria.
  2. To investigate whether prevalence of CCSVI is different between centralized and local CDUS reading of 5 VH CCSVI CDUS criteria.
  3. To investigate the prevalence of CCSVI in patients with MS, compared with the prevalence observed in a control population consisting of OND patients and HC, when bidirectional flow in the intracranial veins and sinuses CDUS criterion is not considered as part of VH CCSVI CDUS criteria.
  4. To determine whether prevalence of CCSVI in patients with MS, compared with the prevalence observed in a control population consisting of OND patients and HC differs when using CDUS velocity and flow parameters in the Internal Jugular Veins (IJVs) and Vertebral Veins (VVs).
  5. To determine the reproducibility of VH criteria by using of centralized and local blinded, controlled CDUS reading assessment.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Observational

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
499

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

5 years to 80 years (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Participants in this study will be those who had participated in the second phase of the Combined Transcranial/Extracranial Venous Deficiency (CTEVD) study.

Description

Inclusion Criteria:

  • Participation in the CTEVD Phase 2 study
  • Available CDUS exam
  • Diagnosed with CIS, MS, OND, or being a HC

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Multiple Sclerosis
Patients diagnosed with Multiple Sclerosis (MS), identified in the CTEVD trial
Clinically Isolated Syndrome
Patients diagnosed with Clinically Isolated Syndrome (CIS), identified in the CTEVD trial.
Other Neurological Disorders
Patients diagnosed with Other Neurological Disorders (OND), identified in the CTEVD trial. ONDs fall into one of four categories: Neurodegenerative, Vascular, Autoimmune, and Neuromuscular; and the following disorders: Acute Disseminated Encephalomyelitis (ADEM); Antiphospholipid Antibody (syndrome; APLA); Atypical, short-lasting neurodegenerative disease; Autoimmune disease not otherwise specified (NOS); Cerebellum Syndrome; Charcot-Marie Tooth Disease; Chiari Malformation; Chronic Fatigue Syndrome; Central Nervous System Vasculitis; Demyelinating Disease; Epilepsy; Headaches; Idiopathic Chronic Neuropathy; Migraines; Mitochondrial Disease; Myelopathy; Neurofibromatosis; Neuropathy; Optic Neuritis; Parasthesia related to Transient Ischemic Attacks (TIA); Parkinson's Disease; Restless legs syndrome; Seizures; Spinal Cerebellum Disease; Spinal Disc Degeneration; Syringomyelia; and Vertigo
Healthy Controls
Individuals who are healthy (i.e., free from neurological conditions; HC) , identified in the CTEVD trial.

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
Number of MS (or CIS) and HC (or OND) who have 5 VH CCSVI CDUS criteria on doppler ultrasound
Time Frame: Baseline
The prevalence (number) of MS/CIS vs. HC/OND who fulfill the 5 venous haemodynamic (VH) criteria on doppler ultrasound.
Baseline

Study record dates

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

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.
July 1, 2014

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.
March 1, 2015

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.
