  • History of active or latent tuberculosis.
  • Any other active infections that would adversely affect participation or investigational medicinal product administration in this study, as judged by the Investigator.
  • Presence of any screening laboratory or electrocardiogram values outside normal limits that were considered in the Investigator's judgment to be clinically significant.
  • Presence of liver injury.
  • At screening, the participant was positive for hepatitis B surface antigen and/or hepatitis B core antibody and/or was positive for hepatitis C antibody.
  • Bleeding disorder or known platelet dysfunction at any time prior to screening visit.
  • Participant had received any live (attenuated) vaccine (including but not limited to varicella zoster, oral polio, and nasal influenza) within 2 months before first treatment visit.
  • Participant was receiving strong inducers or inhibitors of cytochrome P450 3A (CYP3A) or CYP2C8 hepatic enzymes.
  • Participant was receiving anticoagulant/antiplatelet therapies.
  • Participant had taken other investigational drugs within 3 months or 5 half lives, whichever was longer, before screening visit.
  • Participant had an Expanded Disability Status Scale score >5.5 at first screening visit.
  • Participant had a relapse in the 30 days prior to randomization.
  • Participant was pregnant or a breastfeeding woman.
  • History or presence of significant other concomitant illness.
