Correlation Between Multiple Sclerosis Functional Composite (MSFC) and Expanded Disability Status Scale (EDSS) in Patients With Multiple Sclerosis (MS) in Argentina

October 13, 2013 updated by: Merck KGaA, Darmstadt, Germany

The Multiple Sclerosis Functional Composite (MSFC) in the Follow-up of MS Patients: Correlation With the Expanded Disability Status Scale (EDSS) Among Different Clinical Forms in Argentina

This observational study is being conducted to evaluate the usefulness of the MSFC and its relationship with EDSS scores in subjects with MS in Argentina.

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 observational, open-label study is being conducted to correlate change in EDSS score with the change in MSFC scores at the end of a 2-year follow-up period for subjects with MS in Argentina. Measurement of disability is an indispensable parameter in assessing the efficacy of experimental therapeutic agents in MS as well as in trying to determine possible individual evolution of the disease. Clinical scales are being used as primary or secondary outcome measures for recording disease progression in clinical trials. Kurtzke's EDSS is still used as a gold standard for measuring impairment and disability in MS. The MSFC is an examination-based quantitative scoring of neurological impairment. This study aims to establish a correlation between the usefulness of both scales.

OBJECTIVES

Primary Objective:

  • To evaluate the change in MSFC score with change in EDSS scores at end of 2 year follow-up period for subjects with MS in Argentina

Secondary Objectives:

  • To evaluate the cross-sectional correlations in MSFC score at baseline and at 24 months with EDSS score at baseline and at 24 months
  • To describe the MSFC score for MS phenotype in this population
  • To evaluate the predictive validity of MSFC score of a subsequent EDSS change in a subgroup of MS patients in Argentina

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 to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Subjects with MS in 20 sites across Argentina

  • All clinical types: relapsing-remitting MS (RRMS), primary progressive MS (PPMS) and secondary progressive MS (SPMS). Stable disease course without any relapse for at least the previous 3 months
  • Subjects treated or not with disease modifying drugs
  • Ages between 18 and 65 years and is capable of understanding and complying with protocol requirements
  • Subject has a stable residence with no planned move during the entire investigation period

Exclusion Criteria:

  • Life expectancy less than 5 years at admission
  • Diagnosis of clinically isolated syndrome (CIS)
  • Other clinical conditions that mimic MS
  • Psychiatric diseases

  • Pregnancy
  • The subject is unwilling or unable to comply with the protocol or scheduled appointments
  • Subject is unable to understand the language in which the approved informed consent is written
  • The subject is a study site employee, or an immediate family member (i.e., spouse, parent, child, sibling) of a study site employee, involved in conduct of this study

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
- Evaluation of correlations between changes over time
Time Frame: Baseline and two years
- Evaluation of correlations between changes over time for MSFC composite score and arm, leg and cognitive MSFC scores versus EDSS score changes over the same periods
Baseline and two years

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
Time Frame
To evaluate the predictive validity of MSFC score of a subsequent EDSS change in a subgroup of MS patients
Time Frame: Baseline, 1 year, 2 years
Baseline, 1 year, 2 years

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.
August 1, 2008

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.
