A Real-world, Multi-center, Prospective, Observational Study for PNH in China

As a rare disease listed in the First Catalogue of Rare Diseases in China (National Health Commission of the People's Republic of China, 2019), PNH is poorly studied in China subse-quently leading to the inadequate elucidation of disease characteristics and clinical outcomes. Eculizumab was recently approved by NMPA. The availability of Eculizumab in China pro-vides people living with PNH with a new treatment option that can reduce disease symptoms and prevent the dysregulated complement system from causing further damage. A Phase Ⅳ study is necessary to understand the natural history of disease and the clinical outcomes with different medical interventions.
