E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
- All participants who completed their participation in an Alexion sponsored clinical study with danicopan as an add on to a C5i treatment. - Documentation of vaccination for Neisseria meningitidis: All participants must be revaccinated as per national vaccination guidelines or local practice for vaccination use with complement inhibitors. |
|
E.4 | Principal exclusion criteria |
- Any medical condition (for example, cardiac, pulmonary, renal, oncologic, or psychiatric) that, in the opinion of the Investigator, might interfere with participation in the study, pose any added risk to the participant, or confound the assessment of the participant. - Female participants who are pregnant, breastfeeding, or intending to conceive during the course of the study. |
