A Study to Assess the Potential Impact of Disease Modifying Therapies on COVID-19 Outcomes and the Antibody Response Following an Infection With SARS-CoV-2 in Patients With Multiple Sclerosis Within the Swiss Multiple Sclerosis Cohort. (MS COVID-19)

April 22, 2025 updated by: University Hospital, Basel, Switzerland

An Open-label Observation Study to Assess the Potential Impact of Disease Modifying Therapies on COVID-19 Outcomes and the Antibody Response Following an Infection With SARS-CoV-2 in Patients With Multiple Sclerosis Within the Swiss Multiple Sclerosis Cohort.

This nested project of the Swiss Multiple Sclerosis Cohort (SMSC) is to assess the severity of COVID-19 and the magnitude of antibody response after infection with Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) in patients already treated or not with various immunotherapies for multiple sclerosis followed in the framework of the SMSC.

Detailed Description

This nested project of the Swiss Multiple Sclerosis Cohort (SMSC) is to assess the severity of COVID-19 and the magnitude of antibody response after infection with Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) in patients already treated or not with various immunotherapies for multiple sclerosis followed in the framework of the SMSC.

To assess the frequency and severity of SARS-CoV-2 infections and associated symptoms in the study population, data is collected from systematic questioning during the SMSC-visits and from serum samples collected every 6-12 months within the SMSC (for measurement of anti-SARS-CoV-2 antibodies in pre-pandemic reference samples and prospectively to determine the anti-SARS-CoV-2-serostatus during the study period).

Combining the information on anti-SARS- CoV-2 serostatus and infection history opens the opportunity to determine the number of patients without or with only mild vs. moderate to severe COVID-19 symptoms in large groups of patients with Multiple Sclerosis (MS) treated with immunotherapies targeting various components of the immune system.

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

Sampling Method

Probability Sample

Study Population

This study is a nested project within the framework of the SMSC. The SMSC is a prospective multicenter cohort study performed across eight swiss centres. Patients are recruited in the SMSC according to a set of inclusion criteria as specified in the cohort protocol and are only included after a written informed consent is signed.

Description

Inclusion Criteria:

  • all patients in the Swiss Multiple Sclerosis Cohort (SMSC)

Exclusion Criteria:

  • Patients with Neuromyelitis optica and Radiologically Isolated Syndrome will be excluded
  • Existence of a documented refusal of further use of health-related personal data and/or biological material

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
Incidence of severe COVID-19 as defined by the WHO clinical progression scale (Score 6-9)
Time Frame: through study completion, an average of 3 years
Incidence of severe COVID-19 as defined by the WHO clinical progression scale (Score 6-9). The WHO clinical progression scale provides a measure of illness severity across a range from 0 (not infected) to 10 (dead). Incidence of severe COVID-19 infections will be assessed by evaluation of collected data on confirmed SARS-CoV-2-infections and their clinical courses.
through study completion, an average of 3 years
COVID-19 related death defined by the WHO clinical progression scale (Score 10)
Time Frame: through study completion, an average of 3 years
COVID-19 related death defined by the WHO clinical progression scale (Score 10) in untreated and treated patients. The WHO clinical progression scale provides a measure of illness severity across a range from 0 (not infected) to 10 (dead).
through study completion, an average of 3 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
Measure Description
Time Frame
Proportion of patients with Anti-SARS-CoV-2 seroconversion
Time Frame: through study completion, an average of 3 years
Proportion of patients with Anti-SARS-CoV-2 seroconversion
through study completion, an average of 3 years
Change in mean titers of IgM- and IgG-antibodies against SARS-CoV-2
Time Frame: through study completion, an average of 3 years
The Anti-SARS-CoV-2 titer ratios from baseline-samples at pre-pandemic time point to the sample titers during study period will be compared.
through study completion, an average of 3 years

Time Frame: through study completion, an average of 3 years
The Anti-SARS-CoV-2 titer ratios from baseline-samples at pre-pandemic time point to the sample titers during study period will be compared.
