    Baseline through up to Week 52

  • Breakthrough Hemolysis (BTH) In The Presence Of Elevated LDH During Treatment Period With Ravulizumab

    Baseline through up to Week 52

  • +6 more secondary outcomes

Study Arms (1)

Participants With PNH

Data will be collected on participants who were already treated with eculizumab for at least 26 weeks and who started ravulizumab treatment as per clinical practice.

Drug: Ravulizumab

Interventions

Sampling MethodNon-Probability Sample
Study Population

Participants with documented diagnosis of PNH that were already treated with eculizumab and started treatment with ravulizumab and met the inclusion and exclusion criteria.

You may qualify if:

  • Body weight of 10 kilogram or above
  • Hemolysis with clinical symptom(s) indicative of high disease activity
  • Documented diagnoses of PNH confirmed by high-sensitivity flow cytometry evaluation of red blood cells and white blood cells with granulocyte or monocyte clone size of ≥ 5%
  • Clinically stable after having been treated with eculizumab for at least the past 6 months
  • Participant already assigned to ravulizumab treatment as a specific therapeutic strategy within the current routine clinical practice (this decision has to be made independently and before the enrolment of the participant in the study)
  • Vaccinated against Neisseria meningitidis (according to Summary of Product Characteristics) \< 3 years before dosing or at least 2 weeks prior to initiating ravulizumab unless the risk of delaying ravulizumab therapy outweighs the risk of developing a meningococcal infection
  • Signed written informed and privacy consent prior to study participation

You may not qualify if:

  • History of hematopoietic stem cell transplantation (evaluated at baseline)
  • Known pregnant or breastfeeding participant (evaluated at baseline)
  • Participant unable to read and write in Italian language and to autonomously fill in questionnaires and scales (evaluated at enrolment)
  • Participants enrolled in any clinical study receiving experimental treatments for PNH (evaluated at baseline)
  • Hypersensitivity to the active substance or to any of the excipient of the study drug.
  • Participants with unresolved N. meningitidis infection at treatment initiation
  • Participants who are not currently vaccinated against N. meningitidis unless they receive prophylactic treatment with appropriate antibiotics until 2 weeks after vaccination
