In this point-counterpoint digital activity, two expert faculty discuss and debate treatment selection for patients with PNH through case-based scenarios. Faculty review mechanisms of action, clinical trial data, and real-world evidence supporting divergent treatment strategies for the presented cases. How do the experts make their initial treatment selections? Why might they choose a C5 inhibitor or a C3 inhibitor? How do they assess response to treatment, and what do they do when treatment response is suboptimal? View the activity and find out!

This educational activity is designed for hematologists, oncologists, hospital system pharmacists, nurses, and the multidisciplinary healthcare team who are involved in the care of patients with PNH.

Paroxysmal nocturnal hemoglobinuria (PNH) is a rare acquired hematopoietic stem cell disorder that renders blood cells more sensitive to the complement system and is characterized by a variety of symptoms, including hemolytic anemia, hemoglobinuria, thrombosis, and bone marrow failure. PNH has a significant clinical burden and impact on patient quality of life (QoL) due to transfusion dependence and hemolysis, a well-recognized risk factor for thrombosis that can lead to organ failure and insufficiency, and is the primary cause of mortality; however, therapeutic advances have improved survival rates. Indeed, though PNH is rare, there is extensive knowledge regarding its pathophysiology and underlying molecular defects, which supported the development of efficacious mechanism-based therapies.

Until recently, only two treatment strategies—complement component 5 (C5) blockade with either eculizumab or ravulizumab and allogeneic hematopoietic stem cell transplantation—were available for treating PNH. In 2021, the complement protein C3 inhibitor pegcetacoplan was approved to treat PNH. Eculizumab is associated with a greater than 50% reduction in transfusions and a close to 70% reduction in risk of thrombotic events and significant adverse vascular event rates, but nearly 30% of patients may experience breakthrough hemolysis due to insufficient complement inhibition. Ravulizumab has a similar safety and efficacy profile to eculizumab with fewer breakthrough hemolysis episodes and less-frequent dosing, which may contribute to greater patient satisfaction and improved QoL. The complement protein C3 inhibitor pegcetacoplan significantly improved hemoglobin levels and reduced the need for transfusion in a randomized comparison with eculizumab, creating another therapeutic option for patients with PNH. However, formal recommendations for treatment selection are lacking, and clinicians could benefit from expert guidance in this area to assist in the optimal therapeutic strategy for individualized patient care.

Upon completion of this activity, learners will be able to:
• Outline the clinical manifestations of PNH and their role in guiding initial treatment selection and changes in therapy Review the pharmacologic profiles, efficacy, and safety of available complement inhibitors and summarize their use in clinical practice
• Discuss recent advances in PNH therapeutic approaches
• Formulate personalized treatment strategies considerate of patient risks, characteristics, complications, and preferences
