- Willingness and ability to comply with all study visits and procedures.
- Documented diagnosis of PNH, confirmed by high sensitivity flow cytometry.
- Vaccination against Neisseria meningitidis serotypes A, C, W, and Y < 3 years prior to initiation of study treatment; or, if not previously done, vaccination administered no later than one week after the first drug administration.
- Women of childbearing potential: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraception during the treatment period and for approximately 10.5 months after the final dose of crovalimab or for 3 months after the final dose of eculizumab.
