    • Patients with the presence of active or suspected acute or chronic uncontrolled infection or with a history of immunodeficiency, including a positive HIV test result (ELISA and Western blot). An HIV test will not be required; however, previous medical history will be reviewed.
    • Non-malignant medical illnesses that are uncontrolled or whose control may be jeopardized by the treatment with this study treatment.
    • Life-threatening autoimmune and ischemic disorders.
    • Patients with the presence of active or suspected acute or chronic uncontrolled infection
  8. Inadequate end organ function as defined by:

  11. History of, or current alcohol and/or drug misuse/abuse within the past 12 months
  12. Patients with symptomatic cholelithiasis
  13. Patients with abnormal coagulation (PT and PTT elevated by 30% above normal limits).
  14. Patients on continuous anticoagulation therapy. Patients who were on anticoagulant therapy must complete a washout period of at least 10 days and have confirmed normal coagulation parameters before study inclusion (patients receiving aspirin once a day are allowed to be enrolled).
  15. Patients who are hypothyroid and not on adequate replacement therapy
  16. Patients who have undergone major surgery/surgical therapy for any cause within 1 month. Patients should have recovered from the surgery and be in good clinical condition before entering the study.
  17. Patients who have a history of a primary malignancy (or "another" primary malignancy for patients with gastric or esophageal cancer) within the last 1 year, with the exception of locally excised non-melanoma skin cancer, carcinoma in situ of uterine cervix, and excised mucosal gastric cancer or mucosal colon cancer.
  18. Patients with a history of non-compliance to medical regimens or who are considered potentially unreliable or will be unable to complete the entire study.

  21. Participation in any clinical investigation within 4 weeks prior to dosing or longer if required by local regulation. (Use of an investigational drug within 1 month prior to dosing)
  22. Significant acute illness within the two weeks prior to dosing.
  23. Female patients who are pregnant or lactating, or are of childbearing potential (defined as all women physiologically capable of becoming pregnant) and not practicing an effective method of contraception/birth control. Sexually active males must use a condom during intercourse while taking the drug and for 2 months after the last dose of study drug and should not father a child in this period. A condom is required to be used also by vasectomized men in order to prevent delivery of the drug via seminal fluid. Effective contraception methods include:
    • Use of oral, injected or implanted hormonal methods of contraception or
    • Placement of an intrauterine device (IUD) or intrauterine system (IUS)
    • Barrier methods of contraception: condom or occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/ vaginal suppository
    • Total abstinence or patient sterilization (male or female)
