      Trial Summary

      This is a Phase I/II, first-in-human study consisting of four sequential parts and an open-label extension (OLE). The safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of single doses of crovalimab will be evaluated in healthy volunteers (HV) during part 1. The safety, tolerability, PK and PD of multiple doses of crovalimab will be evaluated in participants with paroxysmal nocturnal hemoglobinuria (PNH) in parts 2, 3, 4, and OLE of the study. Efficacy of crovalimab will be evaluated in Parts 2, 3, and 4.

      Inclusion Criteria

      Part 1 (HVs only):

      • Healthy male volunteers, aged between 21 and 55 years inclusive
      • Participants with a negative hepatitis B surface antigen (HBsAg), hepatitis B core antibody (HBcAb), hepatitis C antibody, and human immunodeficiency virus (HIV) test result
      • Participants who have been vaccinated against hepatitis B
      • No evidence of Neisseria meningococci in nasopharyngeal swab
      • Neisseria meningitidis vaccination against serogroups B and A, C, W, and Y
      • Non-smokers, or former smokers, who have not smoked for at least 60 days prior to screening

      Parts 2, 3 and 4 (PNH participants only):

      • Male or female participants with PNH between 18 and 75 years of age
      • Neisseria meningitidis vaccination in accordance with most current local guidelines or standard of care (SOC) for participants at increased risk for meningococcal disease (Part 2 and 4)
      • Participant has been vaccinated with Neisseria meningitidis vaccine(s) in accordance with most current local guidelines or SOC for participants at increased risk for meningococcal disease or is being revaccinated if applicable (Part 3 and 4)
      • Antibiotic prophylaxis for meningococcal infection must be initiated prior to initiation of crovalimab therapy if the time period between initial Neisseria meningitidis vaccination and first dose of crovalimab is less than 2 weeks (Part 2 and 4)
      • Antibiotic prophylaxis of meningococcal infection may be initiated prior to initiation of crovalimab therapy based on local guidelines or SOC for participants at increased risk for meningococcal disease e.g., splenectomized patients (Parts 2 and 4)
      • Stable dose for greater than or equal to (>/=) 28 days prior to screening of other therapies (immunosuppressant therapy, corticosteroids, iron supplements)

      Part 2 and 4 (currently untreated PNH participants who are candidates for treatment with complement inhibitors only):

      • PNH participants who have not been treated with any complement inhibitor or if previously treated stopped treatment due to lack of efficacy based on a single missense C5 heterozygous mutation
      • Serum LDH levels at least 1.5-fold above the ULN at screening
      • Hepatitis B participants can be enrolled if their liver function test values are less than 2 x ULN and there is no liver function impairment

      Part 3 and 4 (PNH participants currently treated with eculizumab only):

      • PNH participants who have been treated continuously with eculizumab for at least 3 months preceding enrollment in the trial
      • Participants receive regular infusions of eculizumab
      • Subjects with a negative hepatitis B surface antigen (HBsAg), hepatitis B core antibody (HBcAb), hepatitis C antibody, and HIV test result

      OLE only - PNH participants:

      • PNH participants who have completed Parts 2, 3 and 4 respectively
      • PNH participants who derived, in the investigator's opinion, benefit from treatment with crovalimab

      Parts 2, 3 and 4 - PNH participants only:

      • Evidence of moderate to severe concurrent renal, liver, cardiac, pulmonary or gastrointestinal disease not related to PNH as determined by the investigator
