Risk of Progressive Multifocal Leukoencephalopathy Among Patients With Multiple Sclerosis Exposed to Zeposia

2026年7月24日 更新者:Bristol-Myers Squibb
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 .

研究人群

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.

描述

Inclusion Criteria:

  • 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.

Exclusion Criteria:

• There are no additional exclusion criteria.

主要结果指标

结果测量
措施说明
大体时间
Proportion of progressive multifocal leukoencephalopathy (PML) cases by participant characteristics and potential risk factors among ozanimod-exposed participants with multiple sclerosis
大体时间:Up to 15 years
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.
Up to 15 years

次要结果测量

结果测量
措施说明
大体时间
Incidence rate of progressive multifocal leukoencephalopathy (PML) among ozanimod-exposed participants overall and by risk factor category
大体时间:Up to 15 years
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.
Up to 15 years
