排除标准

  • Participants are excluded from the study if any of the following criteria apply:

  • - Conditions that may predispose the participant to excessive bleeding
  • - Any participant with an uncontrolled disease state as judged by the Investigator, such as asthma, psoriasis, or inflammatory bowel disease, etc. that are typically treated with oral or parenteral corticosteroids
