简要总结

The aim of this study is to compare the efficacy, safety profile, pharmacokinetics, pharmacodynamics, and immunogenicity of BCD-281 and the reference drug in subjects with relapsing multiple sclerosis.

详细描述

The study includes the following periods:

  • Screening (not more than 28 days from the date of signing the ICF).
  • Double-blind period - Week 0-72.
  • Open-label period - Weeks 72-96.
  • Follow-up period - Weeks 96-100. The screening examination is aimed at confirming the eligibility of the subjects for the study. After confirming the eligibility, the subject will be randomized with equal probability into one of two groups (BCD-281 and the reference drug).
