Real-World Persistence and Adherence of Ofatumumab Compared to Self-Injectable and Oral DMTs in Patients With Multiple Sclerosis

October 15, 2024 updated by: Novartis

This was a retrospective cohort study utilizing the IQVIA PharMetrics® Plus claims database from 01 August 2019 through 31 May 2022.

The database is comprised of fully adjudicated (i.e., paid by the health plan) medical and pharmacy claims and is representative of the commercially insured United States population. Adults treated with ofatumumab (OMB), oral disease-modifying therapies (DMTs) (dimethyl fumarate, diroximel fumarate, monomethyl fumarate, fingolimod, siponimod, ozanimod, ponesimod, teriflunomide, cladribine) or platform self-injectable DMTs (glatiramer acetate, interferon beta-1a, peginterferon beta-1a, interferon beta-1b) between 01 August 2020, through 30 November 2021, were identified. The date of the first incident DMT (OMB, oral DMT, or injectable DMT) during the identification window served as the index date. The baseline period was the 12 months before the index date, and the follow-up period was at least 6 months after the index date. Patients treated with OMB were selected first to maximize sample size, and these patients were allowed to have an oral or injectable DMT in the baseline period. Patients without OMB use during the identification period were categorized into the oral DMT or platform self-injectable DMT cohort based on the first-observed incident DMT during the identification period. For the purpose of this study, platform self-injectable DMTs were referred to as 'self-injectable DMTs.'

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

This was a retrospective, noninterventional cohort study.

Description

Inclusion criteria:

  • Patients with 1 claim or more for ofatumumab, a newly initiated oral DMT (dimethyl fumarate, fingolimod, teriflunomide, cladribine, siponimod, ozanimod, diroximel fumarate, monomethyl fumarate, ponesimod) or a newly initiated self-injectable DMT (daclizumab, glatiramer acetate, interferon beta-1a, peginterferon beta-1a, interferon beta-1b) occurring during the index window.
  • Patients with 12 months or more of pre-index continuous enrollment [CE] with medical and pharmacy benefits.
  • Patients with 6 months or more of post-index CE with medical and pharmacy benefits.
  • Patients with 2 or more non-ancillary outpatient 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 or 1 or more inpatient claims with a diagnosis of MS in the first position during pre-index period.
  • No data quality issues (defined as missing age or sex).
  • Having two DMTs on the same day was very rare in MS patients per clinician's inputs, but if it happened, those patients were excluded from analysis.

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.

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
Number of Patients Persistent on Ofatumumab and Self-injectable Disease-modifying Therapies (DMTs)
Time Frame: Month 6, month 12
Persistence was defined as no evidence of discontinuation of the therapy over the follow-up period. Self-injectable DMTs included daclizumab, glatiramer acetate, interferon beta-1a, peginterferon beta-1a, and interferon beta-1b.
Month 6, month 12

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Number of Patients Persistent on Ofatumumab and Oral Disease-Modifying Therapies (DMTs)
Time Frame: Month 6, month 12
Persistence was defined as no evidence of discontinuation of the therapy over the follow-up period. Oral DMTs included dimethyl fumarate, diroximel fumarate, monomethyl fumarate, fingolimod, siponimod, ozanimod, ponesimod, teriflunomide, and cladribine.
Month 6, month 12
Number of Patients Adherent on Ofatumumab and Oral DMTs
Time Frame: Month 6, month 12
Adherence was based on the proportion of days covered (PDC), calculated as the number of days with the drug on hand divided by the total number of days in the follow-up period. Oral DMTs included dimethyl fumarate, diroximel fumarate, monomethyl fumarate, fingolimod, siponimod, ozanimod, ponesimod, teriflunomide, and cladribine.
