About this study

Official title: Kesimpta® (Ofatumumab) in Swiss Multiple Sclerosis Patients - an Observational Study (KOSMOS)

This is a multi-center, observational study carried out in Switzerland that aims to describe the effects of Ofatumumab in a setting of routine medical care.

Read the detailed description

This non-interventional study will observe the effect of Ofatumumab treatment compared to the standard of care (SoC) arm of a closely monitored phase-IIIb study (STHENOS-COMB157G3301) in MS patients in a real-world setting in Switzerland over an observational period of 12 month.

What is being measured

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

  1. Proportion of patients with no evidence of disease activity (NEDA-3)

    No evidence of disease activity (NEDA-3), as defined by no confirmed MS relapse, no new or enlarging T2 lesions, no Gadolinium-positive T1 lesions, and no six-month confirmed disability worsening, as compared to the SoC arm of STHENOS.

    Measured: Month 12

Secondary outcomes (11)
  1. Proportion of patients demonstrating NEDA-3

    Proportion of patients demonstrating NEDA-3 and its components in relation to the Ofatumumab arm of STHENOS.

    Measured: Month 12

  2. Proportion of patients demonstrating no evidence of disease activity in individual components of NEDA-3

    Proportion of patients demonstrating no evidence of disease activity in individual components of NEDA-3:

    • No confirmed MS relapse
    • No new or enlarging T2 lesions
    • No Gadolinium-positive T1 lesions
    • No six-month confirmed disability worsening

    Measured: Month 12

  3. Proportion of patients with previous DMT medication

    Proportion of patients with previous Disease-modifying Therapy (DMT) medication will be collected

    Measured: Baseline

  4. Proportion of patients with clinical and MRI parameters

    Proportion of patients with Magnet Resonance Imaging (MRI) and clinical parameters will be collected.

    Clinical parameters includes number of T2-hyperintense lesions, T1-contrast-enhancing lesions; number of MS relapse; Extended disability status scale (EDSS)

    Measured: Baseline

  5. Proportion of Ofatumumab doses not completed

    Proportion of Ofatumumab doses not completed and reason for not completion within 14 days of expected date.

    Measured: Month 12

  6. Proportion of participants with a cumulative treatment interruption of more than six months

    Proportion of participants with a cumulative treatment interruption of more than six months, calculated as 6 doses not completed.

    Measured: Month 12

  7. Adherence to Ofatumumab

    Proportion of participants with and without 100% adherence, defined as no dose administered outside of 14 days of expected date

    Measured: Month 12

  8. Proportion of patients permanently discontinuing Ofatumumab

    Proportion of patients permanently discontinuing Ofatumumab during the study, and reasons for discontinuation.

    Measured: Month 12

  9. Interdependency of adherence and clinical outcome in terms of NEDA-3

    Correlation between adherence and clinical outcome in terms of NEDA-3 activity to be measured

    Measured: Month 12

  10. Treatment effect of Ofatumumab on the impact of multiple sclerosis as measured by MSIS-29

    The Multiple Sclerosis Impact Scale (MSIS-29) Questionnaire is a 29-item self-report measure with 20 items associated with a physical scale and 9 items with a psychological scale. Items ask about the impact of MS on day-to-day life in the past two weeks. All items have 5 response options. Higher scores reflect greater impact on day to day life

    Measured: Month 12

  11. Treatment satisfaction with Ofatumumab as measured by TSQM-9

    The TSQM-9 is a patient questionnaire assessing treatment satisfaction with Ofatumumab.

    It consists of 3 subscales: effectiveness, convenience and global satisfaction. Each scale score was calculated by summing individual items and then transformed to a 0-100 scale. Higher summary scores indicate better satisfaction with treatment.

    Measured: Month 12

Questions about this trial

What is this clinical trial studying?

An observational study of Multiple Sclerosis, run by Novartis Pharmaceuticals at 13 sites in Switzerland.

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 5 inclusion and 2 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: finished, as of the sponsor's last update on 14 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 13 sites in Switzerland. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Proportion of patients with no evidence of disease activity (NEDA-3) (time frame: Month 12). 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 14 Apr 2026.
