This study is designed to provide data on the immune response and safety of administering vaccines to relapsing multiple sclerosis (RMS) participants taking ozanimod compared to controls taking interferon-beta's or receiving no disease modifying therapies (DMTs). The data of this study will support the labels for ozanimod in multiple sclerosis (MS) because the effect of ozanimod on the vaccination response of MS participants is of interest to participants and prescribers.


Full study title A Phase 3b, Multicenter, Open-Label Study to Evaluate the Immune Response to, and the Safety of, Vaccines in Participants With Relapsing Forms of Multiple Sclerosis Who Receive Oral Ozanimod Compared to Non-Pegylated Interferon (IFN)-Beta or No Disease Modifying Therapy
Protocol number OCR41304 ID NCT05028634
Phase Phase 3


Inclusion Criteria:

  • Participant has a diagnosis of multiple sclerosis (MS) according to the 2017 revision of the McDonald diagnostic criteria and has relapsing forms of multiple sclerosis (RMS): relapsing-remitting MS (RRMS) or secondary progressive MS with active disease based on recent clinical relapse or MRI lesion activity.

Exclusion Criteria:

  • Participant has history of cancer, including solid tumors and hematological except for basal cell cancer of the skin and carcinoma in situ of the cervix, which are exclusionary if they have not been excised and resolved.

  • Participant has a history of or currently active primary or secondary immunodeficiency.

  • Participant has severely compromised cardiac or pulmonary function for which a systemic hypersensitivity reaction to any of the vaccines would pose a significant risk.

  • Participant has received the seasonal influenza vaccine for the 2021/2022 influenza season prior to Day 1, or history of influenza vaccine for the 2020/2021 influenza season within 6 months prior to Day 1.

  • Participant has previous treatment with one of the following medications or

Interventions within the corresponding timeframe described as follows:

  • Any systemic immunosuppressive treatments with potential overlapping effects with the baseline of this study. Corticosteroids that are by non-systemic routes (e.g., topical, inhaled, intra-articular) are allowed.

  • History of treatment with IV immunoglobulin (IVIg) or plasmapheresis within 4 weeks prior to Day 1.

Participate in a study

Here are some general steps to consider when participating in a research study:

  1. Step

    Contact the research team

    Call or email the research team listed within the specific clinical trial or study to let them know that you're interested. A member of the research team, such as the researcher or study coordinator, will be available to tell you more about the study and to answer any questions or concerns you may have.

    Primary contact

  2. Step

    Get screened to confirm eligibility

    You may be asked to take part in prescreening to make sure you are eligible for a study. The prescreening process ensures it is safe for you to participate. During the prescreening process, you will be asked some questions and you may also be asked to schedule tests or procedures to confirm your eligibility.

  3. Step

    Provide your consent to participate

    If you are eligible and want to join the clinical trial or study, a member of the research team will ask for your consent to participate. To give consent, you will be asked to read and sign a consent form for the study. This consent form explains the study's purpose, procedures, risks, benefits and provides other important information, such as the study team's contact information.

  4. Step


    If you decide to participate in a clinical trial or study, the research team will keep you informed of the study requirements and what you will need to do to throughout the study. For some trials or studies, your health care provider may work with the research team to ensure there are no conflicts with other medications or treatments.
