Non-interventional Study of Subcutaneous Ocrelizumab in Persons With Relapsing-Remitting Multiple Sclerosis (SONATA-MS)

September 15, 2026 updated by: Hoffmann-La Roche

A Prospective Longitudinal Multicenter, Multi-Country, Observational Study Assessing Patient Satisfaction After Subcutaneous Ocrelizumab Administration in Persons With Relapsing-Remitting Multiple Sclerosis (SONATA-MS)

The main purpose of the study is to assess patient-reported satisfaction with subcutaneous (s.c.) ocrelizumab administration in participants with relapsing-remitting multiple sclerosis (RRMS) who are treatment-naive, switching from intravenous (i.v.) ocrelizumab to s.c. ocrelizumab, or switching from a prior disease-modifying therapy (DMT) to s.c. ocrelizumab.

Conditions

Conditions

Intervention / Treatment

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

The study population will consist of participants diagnosed with RRMS who are treated with ocrelizumab s.c. for the first time (initial treatment or treatment switch) as part of their multiple sclerosis (MS) therapy during routine clinical practice

Description

Inclusion Criteria:

  • Diagnosis of RRMS according to the revised McDonald criteria (2017 or 2024 revisions).
  • Initiation of ocrelizumab s.c in accordance with routine clinical practice and local prescribing information.
  • The decision to initiate ocrelizumab s.c. has been made by the treating physician prior to and independently of study participation.
  • Willingness to complete the patient-reported outcome questionnaire TASQ, where applicable.

Exclusion Criteria:

  • Participation in any clinical study involving disease modifying therapies for multiple sclerosis during the study period or at the time of enrollment.
  • Prior treatment with rituximab.
  • Contraindications to ocrelizumab as per the local prescribing information.
  • Severe psychiatric or cognitive impairment that, in the opinion of the treating physician, would preclude informed consent, reliable participation in the study, or completion of patient-reported outcomes.
  • Any condition which, in the opinion of the treating physician, would interfere with participation in the study or the interpretation of study results.
  • For participants participating in a Market Research and Patient Support Program (MAP), inclusion is permitted only when a cross-reference to the unique MAP patient identifier is available.

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.
