About this study

Background: In comparison to general population, persons with Multiple Sclerosis have a higher risk to premature death with an estimate reduced life expectancy from 7 to 14 years. However, risk factors of mortality in MS are not well identified and well known. Following the example of studies carry on cancers survival, socioeconomic status (SES) may have an influence on survival in MS.

Objective: The main objective of ECOVIMUS is to estimate net survival according to SES using the European Deprivation Index as a proxy and other major covariates (gender, initial clinical phase and years of disease onset).

Methods: In order to answer to our main objective, we will use a retrospective cohort of MS patients with a medical follow-up in one of the 18 centers included in SURVIMUS II, with a MS onset between 1960 and 2015 and with an informed vital at the date of December 31st, 2015.

The ecological score of deprivation EDI will be used as a proxy of the socioeconomic status and will be attributed from the geolocalisation to patient's residence address. Net survival is directly associated to the notion of "mortality in excess". This mortality will be estimated comparing the observed mortality in MS patients to mortality in the general population. The advantage of this methodological approach is that cause of death is not needed.

Statistical analysis: The influence of socioeconomic status on the excess of mortality will be estimated thanks to a parametric multivariate model of excess rate mortality. This model will be adjusted on other major covariates (gender, age at disease onset, and initial clinical phase) and will include potential complex effects as non-linearity, non-proportionality and interactions.

Expected results: We expect to highlight some differences of net survival in MS patients according to socioeconomic group as it was already shown in cancers. This study will complete information on factors of mortality excess in MS and knowledge on socioeconomic inequalities encountered all along MS disease course.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Excess mortality survival

    Net survival is defined as the probability of death in a hypothetical setting where the cause of interest (in our case MS) would be the only possible cause of death. It is directly linked to the concept of the "excess mortality due to the studied disease". Net survival can be calculated according to two settings, either the estimator of survival can be calculated from death due to MS while cause of death are known, either it can be calculated from the excess of mortality due to MS compared to the mortality of the general population obtained from mortality table of the generable population.

    Measured: From date of MS onset to the date of patients death or to study cut-off date on 1st January 2016.

Secondary outcomes (2)
  1. European Deprivation Index (EDI) proxy of Socio-Economic Status

    The EDI Score is a combination of weighted ecological variates and is available for each 'IRIS area' (Ilots regroupés pour l'Information Statistique). An IRIS area represents the smallest geographical entity for which census data are available in France.

    The geolocation of each individual address, according to latitude and longitude coordinates, is performed with the system of geographical information (SGI) ARGIS® 10.5. This point of geolocation is correlated to the IRIS area and then an EDI score can be attributed to patients registered in the database. The EDI score can be categorized into quintiles.

    Measured: From date of MS onset to the date of patients death or to study cut-off date on 1st January 2016.

  2. Distance to MS expert care center

    Distance in kilometer by road transport from residence place to MS expert care center

    Measured: From date of MS onset to the date of patients death or to study cut-off date on 1st January 2016.

Questions about this trial

What is this clinical trial studying?

An observational study of C10.114.375.500, run by University Hospital, Caen at 18 sites in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 23 Jan 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 18 sites in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Gilles-Louis DEFER, Professor (0033231064617, defer-gi@chu-caen.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Excess mortality survival (time frame: From date of MS onset to the date of patients death or to study cut-off date on 1st January 2016.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Jan 2020.
