Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this non-interventional secondary use of data study is to evaluate hematological response in patients with paroxysmal nocturnal hemoglobinuria and anemia in the 6-month period after initiation of anti-C5 antibody treatment using real-world data obtained from multiple datasets. The results will be used to contextualize results from the APPOINT-PNH (NCT04820530) trial with iptacopan.
