Active ingredient

Sutimlimab

Sutimlimab is an IgG, subclass 4 (IgG4) monoclonal antibody (mAb) that inhibits the classical pathway (CP) and specifically binds to complement protein component 1, s subcomponent (C1s), a serine protease that cleaves C4. The activities of the lectin and alternative complement pathways are not inhibited by sutimlimab. Inhibition of the classical complement pathway at the level of C1s prevents deposition of complement opsonins on the surface of red blood cells, resulting in inhibition of haemolysis in patients with CAD.
