Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages Any age
  • All sexes
  • No healthy volunteers
  • Child, Adult, Older adult

Study population: Adults diagnosed with multiple sclerosis who have been treated with ozanimod and have reported potential progressive multifocal leukoencephalopathy events identified through the Bristol Myers Squibb safety database, spontaneous post-marketing reports, post-marketing observational studies with primary data collection, or patient support programs.

Who may be able to join

  • Adverse event (AE) report with MedDRA Preferred Term of " John Cunningham virus (JCV) cerebrospinal fluid test positive", " JCV granule cell neuronopathy", or "Progressive multifocal leukoencephalopathy (PML)" reported to the Sponsor between 4-Jun-2026 and 31-Jul-2041.
  • AE report(s) originating from spontaneous post-marketing reports, post-marketing observational studies with primary data collection, or patient support programs.
  • Diagnosis of multiple sclerosis before the initial AE report.
  • Exposure to at least one dose of ozanimod before onset of PML symptoms.
  • PML event assessed as "definite" or "probable" by the adjudication committee.
  • PML assessed as "related" to ozanimod by the adjudication committee.

Who cannot join

  • There are no additional exclusion criteria.

About this study

This study will evaluate the risk of progressive multifocal leukoencephalopathy (PML), a rare brain infection caused by John Cunningham virus (JCV), among people with multiple sclerosis who have been treated with ozanimod. The study will collect and review reported cases of PML to describe patient characteristics and estimate how often PML occurs among people treated with ozanimod. Researchers will assess factors that may be associated with the occurrence of PML, such as age, duration of ozanimod exposure, prior immunosuppressant use, lymphopenia, and JCV antibody status .

What is being measured

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

  1. Proportion of progressive multifocal leukoencephalopathy (PML) cases by participant characteristics and potential risk factors among ozanimod-exposed participants with multiple sclerosis

    Participant characteristics and potential risk factors evaluated include: age at PML symptom onset, duration of ozanimod exposure, prior immunosuppressant use, lymphopenia during ozanimod exposure, lymphopenia at PML diagnosis, duration of lymphopenia, anti-John Cunningham virus (JCV) antibody status within 6 months after ozanimod initiation, anti-JCV antibody status at PML symptom onset, and change in JCV index before PML symptom onset.

    Measured: Up to 15 years

Secondary outcomes (1)
  1. Incidence rate of progressive multifocal leukoencephalopathy (PML) among ozanimod-exposed participants overall and by risk factor category

    Incidence rates will be calculated as the number of PML cases divided by estimated person-years of ozanimod exposure and reported as cases per 100,000 person-years with 95% confidence intervals. Incidence rates will be reported overall and by risk factor category, including age, duration of ozanimod exposure, prior immunosuppressant use, lymphopenia during ozanimod exposure, and anti-John Cunningham virus antibody status within 6 months after ozanimod initiation.

    Measured: Up to 15 years

Questions about this trial

What is this clinical trial studying?

An observational study of Multiple Sclerosis and Progressive Multifocal Leukoencephalopathy, run by Bristol-Myers Squibb at 1 site 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 6 inclusion and 1 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: looking for participants now, as of the sponsor's last update on 29 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact BMS Clinical Trials Contact Center www.BMSClinicalTrials.com (855-907-3286, Clinical.Trials@bms.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Proportion of progressive multifocal leukoencephalopathy (PML) cases by participant characteristics and potential risk factors among ozanimod-exposed participants with multiple sclerosis (time frame: Up to 15 years). 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 29 Jul 2026.
