排除标准
- •Known severe thrombophilia (defined as antithrombin deficiency and/or protein S deficiency and/or protein C deficiency), Any major medical, psychological, or psychiatric condition that could cause the subject to be unsuitable for the study or could interfere with the interpretation of the study results, History of or other evidence of recent alcohol or drug abuse as determined by the Investigator (in the 12 months before screening), Known HIV infection with CD4 count (or T-cell count) of <200 cells/µL within 24 weeks before Screening and Pre-dosing visits.
