Outcome Measures
Primary Outcomes (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.
Ongoing (up to 13 years)
Secondary Outcomes (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
Ongoing (up to 13 years)
Study Arms (2)
Receiving Soliris or Ultomiris
PNH patients of any age, including minors, that are receiving Soliris or Ultomiris
Not receiving Soliris or Ultomiris
PNH patients of any age, including minors, that are not receiving Soliris or Ultomiris
Eligibility Criteria
PNH Patients
You may qualify if:
- Patients of any age, including minors, with a diagnosis of PNH or a detected PNH clone, including patients previously treated with Soliris or Ultomiris and withdrawn from treatment. Patients who are minors must have parent/legal guardian consent and must be willing and able to give assent, if applicable as determined by the Ethics Committees/Institutional Review Boards. Upon attaining adulthood, these patients must be re-consented.
- Ability to comprehend and sign consent to have data entered in the PNH Registry.
You may not qualify if:
- Inability or unwillingness to sign informed consent.
- Patients currently enrolled in an interventional clinical trial for treatment of PNH cannot be enrolled in the Registry at the same time.
