Overview
The goal of this clinical trial is to learn if drug CYB704, a proposed biosimilar to Ocrevus, works to treat multiple sclerosis in the same way as the reference product Ocrevus(R).
The main questions it aims to answer are:
- Is CYB704 distributed in the body in the same way as the reference product (demonstration of pharmacokinetic (PK) similarity)?
- Does have CYB704 the same treatment effect and side effects as the reference product?
Researchers will compare CYB704 to a Ocrevus (Ocrevus-US and Ocrevus-EU) (Participants will:
- Take drug CYB704 or Ocrevus (Ocrevus-US and Ocrevus-EU)
- Visit the clinic for a t least 15 treatment visits, checkups and tests
- Will undergo regular magnetic resonance imaging (MRI) examinations
