- •HIV antibody positive
- •Syphilis antibody positive
- •Active tuberculosis, untreated or inadequately treated latent tuberculosis infection (LTBI)
- •History of serious infection within 3 months prior to screening (defined as requiring hospitalization or intravenous antimicrobial therapy), or history of oral antimicrobial therapy within 1 month prior to screening (e.g., viral infections, opportunistic infections, including but not limited to severe cytomegalovirus or herpes virus infections)
- •Congenital long QT syndrome or a corrected QTcF interval of ≥480 ms at screening (unless secondary to pacemaker or bundle branch block)
- •Uncontrolled hypertension (blood pressure ≥160/100 mm Hg repeatedly), unstable angina, congestive heart failure (greater than New York Heart Association class II), electrocardiographic evidence of acute ischemia, coronary angioplasty or myocardial infarction within 6 months prior to screening, uncontrolled atrial or ventricular cardiac arrhythmia, poorly controlled diabetes or other endocrine diseases, severe chronic pulmonary disease, or other serious medical condition which is likely to significantly impair the patient's ability to tolerate the study treatment
- •history of organ transplant
