The positive CHMP opinion was supported data from pharmacokinetic bridging studies comparing VUMERITY and TECFIDERA® (dimethyl fumarate) to determine bioequivalent exposure of monomethyl fumarate, the active metabolite, and relied partially on the well-established long-term safety and efficacy profile of TECFIDERA.
It is designed to block viral attachment and entry into human cells, thus neutralizing the virus, potentially treating COVID-19. volunteers to evaluate the safety, tolerability, pharmacokinetics and immunogenicity. Point mutations were introduced into the native human IgG1 antibody to mitigate effector function.
The antibody binds to an epitope on SARS-CoV-2 that is shared with SARS-CoV-1 (the virus that causes SARS), indicating that the epitope is highly conserved, and less likely to mutate over time. Its current development pipeline consists of product candidates targeting COVID-19, hepatitis B virus, influenza A and human immunodeficiency virus.
