  • Evidence of active malignant disease or malignancies diagnosed within the previous 3 years including hematological malignancies and solid tumors.
  • Participants with other forms of myositis.
  • As per investigator discretion, participants with significant muscle damage (for example, severe muscle atrophy, end stage muscle disease)
  • History of Neisseria meningitidis infection.
  • Human immunodeficiency virus (HIV) infection (evidenced by HIV Type 1 or Type 2 antibody titer).
