Mechanism of action

APRIL is a TNF superfamily member that promotes B cell survival and plasma cell differentiation, contributing to autoimmune disease pathology. By blocking APRIL, SAR342434 reduces pathogenic B cell responses and autoantibody production. This mechanism is particularly relevant in systemic lupus erythematosus and other B cell-driven autoimmune conditions.
