A Single Ascending Dose Study of GZ402668 in Patients With Progressive Multiple Sclerosis

A Randomized, Double-blind, Placebo-controlled Study of Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of a Single Subcutaneous Dose of GZ402668 in Men and Women With Progressive Multiple Sclerosis

Primary Objective:

To assess the safety and tolerability of GZ402668 after a single subcutaneous (SC) dose in men and women with progressive multiple sclerosis.

Secondary Objectives:

To assess in men and women with progressive multiple sclerosis:

• The pharmacokinetic (PK) parameters of GZ402668 after a single SC dose.
• The pharmacodynamic (PD) response to GZ402668 after a single SC dose.

Study Overview

• Status: Completed
• Conditions: Progressive Multiple Sclerosis
• Intervention / Treatment: Drug: GZ402668; Drug: Acyclovir; Drug: Placebo

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.
