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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Adult patients who had a first claim for either ofatumumab or ocrelizumab from August 20, 2020, with no claim for either drug during the preceding 12 months.

Description

Inclusion criteria:

Pooled OMB and OCR Cohorts:

  • ≥1 incident claim for OMB (Pooled OMB Cohort) or OCR (Pooled OCR Cohort) in the patient identification period (index date = first claim date).
  • No claims for OMB or OCR within the 12 months prior to the index date.
  • ≥2 outpatient (OP) medical claims (at least 30 days apart) with a diagnosis code for MS (International Classification of Diseases, 10th Revision, Clinical Modification [ICD-10-CM] code: G35) in any position, with the first claim occurring in the 12 months prior to or on index date and the second claim up to 6 months after index date, or ≥1 inpatient (IP) claim with a diagnosis of MS in the first position in the 12 months prior to or on index date.
  • ≥18 years of age on index date.
  • Continuous healthcare plan enrollment for ≥12 months prior to index date (baseline period) and ≥6 months after index date (follow-up period).
  • Persistent use of OMB (Pooled OMB Cohort) or OCR (Pooled OCR Cohort) for ≥6 months after index date.

Treatment-naïve OMB and OCR Cohorts:

  • Included in Pooled OMB Cohort or Pooled OCR Cohort.
  • No claims for a disease modifying therapy (DMT) used for the treatment of MS within the 12-month baseline period.

Exclusion criteria:

• None.

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.
Pooled OMB Cohort
Adult MS patients, including treatment-naïve and treatment-experienced patients, with a first claim for OMB from August 20, 2020.

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
Measure Description
Time Frame
Annualized Relapse Rate (ARR) in Treatment-Naïve Patients
Time Frame: Up to approximately 3 years and 11 months
ARR was defined as the number of relapse episodes per patient-year (PPY) during the follow-up period.
Up to approximately 3 years and 11 months

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
Measure Description
Time Frame
ARR in All Patients
Time Frame: Up to approximately 3 years and 11 months
ARR was defined as the number of relapse episodes per PPY during the follow-up period.
Up to approximately 3 years and 11 months
Healthcare Visits PPY
Time Frame: Up to approximately 3 years and 11 months
Healthcare visits included IP stays, OP visits, and emergency department visits.
Up to approximately 3 years and 11 months
Inpatient Days PPY
Time Frame: Up to approximately 3 years and 11 months
Up to approximately 3 years and 11 months
Difference in Healthcare Costs in OMB Versus OCR
Time Frame: Up to approximately 3 years and 11 months
Healthcare costs included IP, OP, emergency department, and pharmacy costs.
Up to approximately 3 years and 11 months

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.
October 25, 2024

Primary Completion (Actual)

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.
