An Efficacy and Safety Study With Integrated Pharmacokinetics (PK) and Pharmacodynamic (PD) Assessment to Compare the Proposed Ocrelizumab Biosimilar CYB704 and Ocrevus in Participants With Relapsing Multiple Sclerosis (RMS)
Purpose
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
