Pharmacology
Siponimod is an S1P receptor modulator that binds with high affinity to S1P receptors 1 and 5, blocking lymphocyte egress from lymph nodes and reducing peripheral blood lymphocyte counts; the therapeutic mechanism in multiple sclerosis is unknown but may involve reduction of lymphocyte migration into the central nervous system.
Anti-CD20 chimeric monoclonal IgG1 antibody with reduced fucose content; binds CD20 on pre-B and mature B lymphocytes and causes cell lysis via antibody-dependent cellular cytolysis and complement-dependent cytolysis.
