• Have a screening 12-lead ECG with clinically relevant abnormalities that may affect the participant's safety or the interpretation of study results.
• Have any of the following active or recent infections:

• serious infection requiring hospitalization or parenteral antibiotics within 12 weeks prior to Day 1, serious bone/joint infection within 24 weeks, or history of infection of an artificial joint;
• active herpes simplex or herpes zoster outbreak within 12 weeks prior to Day 1;
• active infection requiring systemic antimicrobial treatment within 4 weeks prior to Day 1, or superficial skin infection requiring antibiotics within 1 week prior to Day 1;
• active TB; or (e) immunocompromised status posing unacceptable risk per investigator judgment.
