NCT02282826

Brief Summary

Primary Objective: To assess the safety and tolerability of GZ402668 after ascending single intravenous (IV) and subcutaneous (SC) doses in men and women with progressive multiple sclerosis. Secondary Objectives: To assess the following in men and women with progressive multiple sclerosis:

  • The pharmacokinetic (PK) parameters of GZ402668 after ascending single IV doses.
  • The pharmacodynamics (PD) of GZ402668 after ascending single IV doses.
  • The PK parameters of GZ402668 after ascending single SC doses.
  • The PD of GZ402668 after ascending single SC doses.
