NCT06847724

Brief Summary

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 at least 15 treatment visits, checkups and tests
  • Will undergo regular magnetic resonance imaging (MRI) examinations
