About

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).

444 participants in 3 patient groups

ABP 692

Experimental group

Description:

Participants affected by relapsing-remitting multiple sclerosis (RRMS) will receive an initial dose of 300 mg ABP 692 intravenous (IV) infusion on Day 1, followed by a second dose of 300 mg ABP 692 IV infusion on Day 15. A subsequent dose of 600 mg ABP 692 IV infusion will be administered 24 weeks after the initial dose.

Treatment:

Drug: ABP 692

Ocrelizumab (US)/ABP 692

Experimental group

Description:

Participants affected by RRMS will receive an initial dose of 300 mg Ocrelizumab (US) IV infusion on Day 1, followed by a second dose of 300 mg Ocrelizumab (US) IV infusion on Day 15. At Week 24, the treatment will switch to a 600 mg Ocrelizumab (US) IV infusion of ABP 692.

Treatment:

Drug: ABP 692

Drug: Ocrelizumab (US)

Ocrelizumab (EU)
