Clinical Trial Summary

The presence of abnormalities in the cerebral venous circulation, defined as Chronic Cerebrospinal Venous Insufficiency (CCSVI), has recently been reported in patients with Multiple Sclerosis (MS), in healthy subjects and in subjects with other neurological diseases. These reports have aroused much interest both in the scientific world and, above all, among the communities of patients and Associations having the aim of aiding people with MS and of promoting scientific research into this disease.

In the literature published so far there is a lack of verification in large samples of the prevalence of CCSVI in MS compared with that observed in healthy subjects and in those with other diseases of the nervous system.

This is an observational study investigating the prevalence of CCSVI in subjects with MS and comparing it with the prevalence observed in a control population consisting of Healthy Controls (HC) and in a population affected by other neurological diseases of the central nervous system of degenerative, vascular, inflammatory and autoimmune origin.

A total of at least 1,200 adults with MS will be included in the study, as well as 400 healthy subjects and 400 subjects with other neurodegenerative diseases.

Description:

It has been recently reported the possible presence of abnormalities in the cerebral venous circulation of people with MS, in healthy controls and in people with other neurological diseases. These reports have aroused much interest both in the scientific world and, above all, among the communities of patients and Associations having the aim of aiding people with MS and of promoting scientific research into this disease. In particular, the studies by Zamboni and colleagues (Ferrara University) and by Zivadinov and colleagues (University of Buffalo) have suggested an association between CCSVI and MS that was widely reported by the mass media world-wide.

It can be noted that in the literature published so far there is a lack of verification in large samples of the prevalence of CCSVI in MS compared with that observed in healthy subjects and in those with other diseases of the nervous system. The recent and authoritative contributions from the scientific community involved with MS stressing the need for closely controlled and suitably designed clinical studies for investigating the hypotheses suggested with regard to CCSVI (with the necessary thoroughness and with the promptness demanded by the public opinion) are therefore definitely justified.

The possibility that there may be a new pathogenic mechanism underlying the development of MS, not in line with the majority of the experimental data concerning the aetiopathogenesis of this disease, has produced a strong echo throughout the scientific community. Increasingly, in recent months, both the working groups mentioned above and new authors have developed further research studies in order to confirm and extend the results obtained and to lay scientifically sound foundations for possible therapeutic applications for this discovery.

The Fondazione Italiana Sclerosi Multipla (FISM) Onlus, in its capacity as Promoter of this study, wishes, responsibly, to produce the best possible answer for people with MS all over the world. It therefore feels that it is necessary to proceed with the utmost scientific thoroughness, initially by means of a large-scale sample study for evaluating the prevalence of venous abnormalities in MS compared with that observed in normal controls and in controls with other diseases of the nervous system. In this context, the features of this study that distinguish it from previous studies and from the current state of knowledge are the following:

1. Blind multi-Site observational study using the Echo-Color-Doppler equipment assigned to the study;

2. Size of the sample with MS, of at least 1200 study subjects;

3. Evaluation of the prevalence of CCSVI and of other malformations of the venous haemodynamics in the Clinically Isolated Syndrome (CIS), Relapsing-Remitting (RR), Primary Progressive (PP) and Secondary Progressive (SP) forms of MS, using a larger sample than those involved up to the present time.

In this observational study, the prevalence of CCSVI and of other malformations of the venous haemodynamics will be evaluated in different forms of MS and in other diseases of the nervous system. This is therefore an observational study investigating the prevalence of CCSVI in subjects with MS and comparing it with the prevalence observed in a control population consisting of healthy subjects and in a population of people with other neurological diseases of the central and peripheral nervous system of degenerative, vascular, inflammatory and autoimmune origin.

The study is a multi-Site observational study. A total of at least 1,200 adults with MS will be included in the study, as well as 400 healthy subjects and 400 subjects with other neurodegenerative diseases.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Prevalence of CCSVI	The prevalence of CCSVI in MS (overall and in its various different forms) will be estimated, with 95% confidence intervals, and compared with that of the other groups. The differences in the prevalence of CCSVI between the various groups will be evaluated using the chi-square test. The sensitivity, specificity and accuracy of the method will be estimated with their 95% confidence intervals. Values of p equal to or lower than 0.05 will be considered significant.	The primary outcome will be assessed at enrollment (day 1). No follow-up is planned.
