Effectiveness of Ofatumumab in Real-world Practice

CompletedN/A

Sponsor: Novartis Pharmaceuticals

Conditions: Multiple Sclerosis

Countries: United States

This study used a retrospective single cohort pre-post design on Optum® Clinformatics® Data Mart (CDM) data from 20 August 2019 to 31 December 2023 (study period). Patients with a diagnosis of multiple sclerosis (MS) treated with ofatumumab (OMB) between 20 August 2020 (U.S. Food and Drug Administration \[FDA\] approval date) and 01 July 2023 (patient identification window) were included in the study population. The date of the first OMB claim within the patient identification window was defined as the index date. Outcomes, including annualized relapse rate (ARR) and MS-related healthcare resource utilization (HCRU), were measured across two distinct periods. The pre-index period was defined as the fixed 12-month period prior to the index date, during which demographic and clinical characteristics were also assessed. The post-index period was defined as the variable period of ≥6 months after the index date, extending until the earliest between the end of persistent OMB use (defined as last day of OMB supply before a gap of ≥60 days or switch to another disease modifying therapy \[DMT\]), discontinuation of enrollment, or end of study period on 31 December 2023.
