    4. Previous treatment with immunosuppressive agents such as cyclophosphamide, chlorambucil, mycophenolate mofetil (or equivalent), cyclosporine, tacrolimus or azathioprine within 90 days prior
    5. Administration of any live vaccination within 4 weeks prior to Day 1

    7. Use of other investigational drugs within 30 days
    8. History of malignancy of any organ system (other than localised basal cell carcinoma of the skin or in-situ cervical cancer), treated or untreated,
    9. History of clinically significant ECG abnormalities
    10. Presence or suspicion (based on judgment of the investigator) of active infection
    11. Pregnant or lactating

    13. History of any porphyria metabolic disorder
    14. History of solid organ or bone marrow transplantation
    15. History of recurrent severe allergic reactions which in the opinion of the investigator deem the subject unsuitable for participation
    16. Any surgical or medical condition which might significantly alter the absorption, distribution, metabolism, or excretion of drugs, or which may jeopardize the subject in case of participation in the study.
    17. Chronic infection with Hepatitis B (HBV) or Hepatitis C (HCV)
