Caplacizumab: A game changer also in pregnancy-associated immune-mediated thrombotic thrombocytopenic purpura?

Therapeutic options in immune-mediated thrombotic thrombocytopenic purpura (iTTP) during pregnancy are limited besides therapeutic plasma exchange (TPE) and corticosteroids. The report by Odetola et al. suggests that caplacizumab represents a reasonable option in iTTP during pregnancy, especially when the disease is not rapidly controlled with the standard TPE-corticosteroid association.
