Safety Study of GNbAC1 Monoclonal Antibody in Healthy Male Volunteers

Phase 1
Completed
Conditions
Healthy Volunteers

Registration Number
NCT02452996
Lead Sponsor
GeNeuro Innovation SAS
Brief Summary

In this clinical study, the safety and tolerability of GNbAC1 as a treatment for MS patients will be evaluated in healthy male volunteers.

Detailed Description

The monoclonal antibody, GNbAC1, targets the envelope protein (Env) of the human endogenous retrovirus (HERV), also called multiple sclerosis associated retrovirus (MSRV), which is considered as a critical factor in the development of multiple sclerosis.

This study will assess the pharmacokinetics, safety and tolerability of GNbAC1 following single ascending doses (6, 18, and 36 mg/kg) administered via IV infusion.
