What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Evaluate safety data specific to the use of Soliris and Ultomiris

    Primary analyses will assess safety endpoints, including occurrence and time to first event for the following: meningococcal infections, infections with serious outcomes, formation of human anti-drug antibodies (ADA) to Soliris and Ultomiris, malignancy, thrombotic events, pulmonary hypertension, impaired renal function, impaired hepatic function, hemolysis, pregnancies, lactation, infusion reactions, bone marrow transplant, serious adverse events, and mortality.

    Measured: Ongoing (up to 13 years)

Secondary outcomes (1)
  1. Collect data to characterize the progression of PNH as well as clinical outcomes, mortality and morbidity in Soliris or Ultomiris and non-Soliris or non- Ultomiris treated patients

    Secondary analyses will include descriptions of patient populations, PNH specific treatments, concomitant medications, progression of disease, PNH clone sites, clinical symptoms, and clinical outcomes.

    Measured: Ongoing (up to 13 years)
