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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Probability Sample

Study Population

The study population will include participants with RMS who are receiving BRIUMVI® (ublituximab-xiiy).

Description

Inclusion Criteria:

  1. Confirmed Multiple Sclerosis (MS) diagnosis.
  2. Participants who have not received any BRIUMVI® (ublituximab-xiiy) infusion prior to study start. Participants who have been prescribed BRIUMVI® (ublituximab-xiiy) but have not yet received their first infusion on Day 1 of 150 milligrams (mg) can be included.

Exclusion Criteria:

  1. Have received any live or live-attenuated vaccines (including for varicella-zoster virus or measles) within 4 weeks prior to first BRIUMVI® (ublituximab-xiiy) administration or any non-live vaccines within 2 weeks prior to first BRIUMVI® (ublituximab-xiiy) administration.
  2. Any active infection (e.g., active Hepatitis B virus [HBV])
  3. Concurrent participation in any interventional MS trials, or planned concurrent treatment with other Multiple Sclerosis Disease Modifying Therapy (MS DMT) during the study period.

Study Plan

This section provides details of the study plan, including how the study is designed and what the study is measuring.

Design Details

  • Observational Models: CASE_ONLY
  • Time Perspectives: PROSPECTIVE

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
BRIUMVI® (Ublituximab-xiiy)

Participants will receive BRIUMVI® (Ublituximab-xiiy) intravenous (IV) infusion for the treatment of RMS.
Other: No Intervention

No Intervention

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.
Outcome Measure
Time Frame
Annualized Relapse Rate (ARR)
Time Frame: Up to Week 96
Up to Week 96

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Percentage of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs)
Time Frame: Up to Week 96
Up to Week 96
Number of Participants with Infusion Related Reaction (IRR) at Each Infusion
Time Frame: Up to Week 96
Up to Week 96

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
July 22, 2024

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
April 1, 2032

Study Completion (Estimated)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.

Study Registration Dates

First Submitted

First Submitted

The date on which the study sponsor or investigator first submitted a study record to ClinicalTrials.gov. There is typically a delay of a few days between the first submitted date and the record's availability on ClinicalTrials.gov (the first posted date).

First Submitted That Met QC Criteria

First Submitted That Met QC Criteria

The date on which the study sponsor or investigator first submits a study record that is consistent with National Library of Medicine (NLM) quality control (QC) review criteria. The sponsor or investigator may need to revise and submit a study record one or more times before NLM's QC review criteria are met. It is the responsibility of the sponsor or investigator to ensure that the study record is consistent with the NLM QC review criteria.
May 23, 2024

First Posted (Actual)

First Posted

The date on which the study record was first available on ClinicalTrials.gov after National Library of Medicine (NLM) quality control (QC) review has concluded. There is typically a delay of a few days between the date the study sponsor or investigator submitted the study record and the first posted date.
