About this study

Official title: An Open-label Multicenter Study to Assess Response to COVID-19 Vaccine in Participants With Multiple Sclerosis Treated With Ofatumumab 20 mg Subcutaneously

This study evaluated if relapsing multiple sclerosis (MS) participants treated with ofatumumab 20 mg subcutaneous (s.c.) administered once monthly could develop an adequate immune response to the COVID-19 mRNA vaccine compared to participants on an interferon or glatiramer acetate.

Read the detailed description

This was a six-cohort, multicenter, prospective study planned for up to 88 relapsing multiple sclerosis (MS) participants. The study was intended to address two questions: 1) Can participants treated with ofatumumab develop an immune response if receiving a COVID-19 mRNA vaccine two weeks prior to ofatumumab start? 2) If receiving COVID-19 mRNA vaccine after introduction of ofatumumab treatment, can participants develop an immune response? Cohort 1: participants received an mRNA COVID-19 vaccine at least two weeks prior to ofatumumab start. Cohort 2: participants received an mRNA COVID-19 vaccine at least four weeks after beginning ofatumumab. Cohort 3: participants on an interferon or glatiramer acetate who received COVID-19 mRNA vaccine. Cohort 4: participants fully vaccinated with an RNA COVID-19 vaccine at least four weeks after ofatumumab start. Cohort 5: participants vaccinated with an RNA COVID-19 vaccine, with or without a booster dose, and on interferon or glatiramer acetate. Cohort 6: participants fully vaccinated with an RNA COVID-19 vaccine who received a booster dose at least four weeks after ofatumumab start. Participants obtained the COVID-19 mRNA vaccine from their HCP (private insurance) or appropriate federal, state or local program.

Participants in Cohort 1 received loading doses of ofatumumab and subsequent dosing was 20 mg s.c. administered monthly. All other cohorts continued current dosing schedule of either ofatumumab, glatiramer acetate or interferon. Participation in trial was maximum of 421 days which was dependent on the Cohort.

What is being measured

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

  1. Percentage of Participants With Response by SARS-CoV-2 Qualitative IgG Antibody Assay at 14 Days Post-vaccination by Cohort Group and Overall, Non-response Imputation Approach (Safety Analysis Set)

    An immune response is defined as a positive SARS-CoV-2 qualitative IgG antibody assay ≥14 days after full course [2 doses] vaccination to non live mRNA COVID-19 vaccine, Participants with a negative or borderline result were considered non-responders, as well as participants with a missing or invalid immune response assessment at 14 days post-vaccination (imputed as non-responders).

    Measured: Cohorts 1 - 3: >=14 days after vaccination: Day 36 (Pfizer) or Day 43 (Moderna); Cohorts 4-6: Day 1

Secondary outcomes (2)
  1. Percentage of Patients With an Immune Response by SARS-CoV-2 Qualitative IgG Antibody Assay by Time Point, Cohort Group and Overall, Non-response Imputation Approach (Safety Analysis Set)

    An immune response is defined as a positive SARS-CoV-2 qualitative IgG antibody assay ≥14 days after full course [2 doses] vaccination to non live mRNA COVID-19 vaccine, Participants with a negative or borderline result were considered non-responders, as well as participants with a missing or invalid immune response assessment at 14 days post-vaccination (imputed as non-responders).

    Measured: Vaccination up to 70, 180, 270 and 360 days

  2. Percentage of Participants Achieving Immune Conversion by Individual Cohort Group and Overall, Non-response Imputation Approach (Safety Analysis Set)

    Immune conversion was defined as (i) pre-vaccination absence of SARS-CoV-2 qualitative IgG antibody with any post-vaccination positive SARS-CoV-2 qualitative IgG antibody assay (Cohorts 1-3 only); or (ii) pre vaccination presence of SARS-CoV-2 quantitative IgG antibody (i.e., pre vaccination value ≥0.80 U/mL) with any post-vaccination ≥4-fold increase in SARS-CoV-2 quantitative IgG antibody titer (Cohorts 1-3 only); or (iii) initial negative SARS-CoV-2 nucleocapsid antibody assay with any post-vaccination positive SARS-CoV-2 qualitative IgG antibody assay (Cohorts 4 and 5 only). There was no baseline for Cohort 6 because there was no blood collection prior to vaccination.

    Measured: Cohorts 1 - 3: >=14 days after vaccination: Day 36 (Pfizer) or Day 43 (Moderna); Cohorts 4-5: Day 1

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Ofatumumab, mRNA COVID-19 vaccine and interferon or glatiramer acetate in people with Relapsing Multiple Sclerosis (RMS), run by Novartis Pharmaceuticals at 7 sites in United States.

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 9 inclusion and 4 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: stopped early, as of the sponsor's last update on 16 May 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 7 sites in United States. 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 20 Jun 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Percentage of Participants With Response by SARS-CoV-2 Qualitative IgG Antibody Assay at 14 Days Post-vaccination by Cohort Group and Overall, Non-response Imputation Approach (Safety Analysis Set) (time frame: Cohorts 1 - 3: >=14 days after vaccination: Day 36 (Pfizer) or Day 43 (Moderna); Cohorts 4-6: Day 1). 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 16 May 2025.
