Non-transplant PNH therapies include anti-C5 monoclonal antibodies that reduce terminal complement activation (eculizumab, ravulizumab, and crovalimab) and proximal complement pathway inhibitors such as pegcetacoplan (C3 inhibitor), iptacopan (complement factor B inhibitor), and danicopan (complement factor D inhibitor). This evidence concerns the gene CFD and paroxysmal nocturnal hemoglobinuria.
