Paradoxical Findings in Patients with Paroxysmal Nocturnal Hemoglobinuria Treated with C5 Inhibitors: Suboptimal Disease Control Perceived As Satisfactory

Introduction: The introduction of C5 inhibitors (C5i) for the treatment of patients with paroxysmal nocturnal hemoglobinuria (PNH) has resulted in lower morbidity and mortality rates. However up to 86% of patients still experience anemia and fatigue in 63% of them which may impact their quality of life (QoL). The SATURNO study aimed to assess PNH patient and physician satisfaction with C5i treatment, along with the impact of the disease and clinical outcomes.
