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.

Detailed Description

The total study duration from screening for a patient can be approximately up to 8 weeks.

Upon completion of this trial, patients treated with GZ402668 will be required to enroll in a 4 year safety follow-up study for continued safety observation.
