Real-World study tests MS drug ofatumumab in greek clinics
NCT ID NCT06486779
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study follows 160 people with relapsing multiple sclerosis in Greece who are already taking ofatumumab (Kesimpta®) as part of their routine care. Researchers will track how many patients have no signs of disease activity—like relapses, new brain lesions, or worsening disability—over time. The goal is to see if the drug works as well in real-world settings as it did in earlier clinical trials.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- ofatumumab (Kesimpta®)
- What this could lead to
- If successful, this study could confirm that ofatumumab works as well in everyday clinics as it does in controlled trials, supporting its use for relapsing MS.
- What could go wrong
- This is an observational study, not a controlled experiment, so results may be influenced by patient selection or other factors. It is also limited to Greece, so findings may not apply everywhere.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
Adult patients with RMS who have initiated treatment with ofatumumab early in their disease course. Patients will have been administered ofatumumab (Kesimpta®) three to six months prior to informed consent (IC) and will continue to be treated according to the local product's prescribing information and routine medical practice in terms of visit frequency and type of assessments performed, after enrolment.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Written IC must be obtained before participating in the study. 2. Patients with diagnosis of RMS per McDonald Criteria (2017) and \<5 years since first MS symptom prior to initiation of ofatumumab. 3. Patients who have been on treatment with ofatumumab for at least 3 months, but not longer than 6 months prior to inclusion in the study. 4. Ofatumumab treatment in line with the European Product Information of Kesimpta (i.e., adult patients with relapsing forms of MS with active disease defined by clinical or imaging features). 5. Patients with at least one available brain MRI scan performed at least 3 months after ofatumumab initiation OR for whom the physician (as per her/his routine practice and independently of his/her decision to include the patient in the current study) plans to perform such scanning within 31 days after patient's inclusion in the study. Notes: This MRI scan can be either brain gadolinium enhanced (Gd+) or not. In case it is not gadolinium enhanced, the most recent MRI prior to ofatumumab treatment should be brain gadolinium enhanced, for relevant comparison and identification of new lesions. This MRI scan will serve as the index reference assessment for the evaluation of NEDA-3 radiological component and shall not have been performed within 30 days after the termination of steroid therapy. 6. Patients willing and able to complete the assessments, including PRO questionnaires, as per physicians' clinical practice and as outlined in this study. Exclusion Criteria: 1. Use of investigational drugs during the study, OR between ofatumumab initiation and inclusion into the study, OR within 3 months before ofatumumab initiation, OR within 5 half-lives of investigational drug before ofatumumab initiation, OR until the expected pharmacodynamic effect has returned to baseline, whichever is longer. 2. Currently pregnant (or intention to become pregnant within the study period), breastfeeding or lactating women.
