Comparison Between ABP 692 and Ocrevus® (Ocrelizumab)

Phase 3RecruitingNCT06700343

Amgen444 enrolled

Overview

The main objectives of the study are to demonstrate pharmacokinetics (PK) similarity between ABP 692 and Ocrelizumab (US), and ABP 692 and Ocrelizumab (EU), and to demonstrate pharmacodynamics (PD) similarity between ABP 692 and Ocrelizumab reference product (RP) based on assessment of the suppression of new active brain lesions over 24 weeks as assessed by magnetic brain imaging (MRI).

Number of Participants Experiencing Treatment-emergent Adverse Events (TEAEs)

An adverse event (AE) is any untoward medical occurrence in a clinical study participant irrespective of a causal relationship with the study treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a treatment, combination product, medical device, or procedure. A TEAE is defined as an AE that starts or worsens on or after the first IP infusion up to the end of study visit.
