Assessing the HERV-W Env ANtagonist GNbAC1 for Evaluation in an Open Label Long-term Safety Study in Patients With Multiple Sclerosis (ANGEL-MS)

October 19, 2020 updated by: GeNeuro SA

A Long-Term International, Extension of Study GNC-003 With GNbAC1 in Patients With Relapsing Remitting Multiple Sclerosis

The humanised IgG4 monoclonal antibody GNbAC1 targets the envelope protein (Env) of the human endogenous multiple sclerosis-associated retrovirus (HERV-W MSRV), which may play a critical role in multiple sclerosis.

The study assesses the long-term safety of GNbAC1 in patients with RRMS and the long-term efficacy of GNbAC1 in terms of MRI outcomes, relapse rate, disability and disease progression.
