• Concurrent participation in another therapeutic clinical trial.
• Requires treatment with proton-pump inhibitors (e.g., omeprazole, esomeprazole, lansoprazole, dexlansoprazole, rabeprazole, or pantoprazole). Patients receiving proton pump inhibitors who switch to H2-receptor antagonists or antacids are eligible for enrolment into this study.
• Received any investigational drug within 30 days or 5 half-lives (whichever is shorter) before first dose of study drug.

• Medical conditions
• Evidence of disease (such as severe or uncontrolled systemic diseases, including uncontrolled hypertension and renal transplant) that, in the investigator's opinion, make it undesirable for the patient to participate in the study or that would jeopardize compliance with the protocol [e.g. a single score of 4 on one single category on the CIRS-G-Score (but not a cumulative score of 4)].
• Severe psychiatric or neurologic disease that, in the investigator's opinion, make it undesirable for the patient to participate in the study or that would jeopardize compliance with the protocol.

• Any active significant infection (e.g., bacterial, viral or fungal) as assessed by the investigator.
• History of or ongoing confirmed progressive multifocal leukoencephalopathy (PML).
• Serologic status reflecting active hepatitis B or C infection.
  • Patients who are hepatitis B core antibody (anti-HBc) positive and who are hepatitis B surface antigen (HBsAg) negative will need to have a negative PCR result before randomization and must be willing to undergo DNA PCR testing during the study. Those who are HBsAg-positive or hepatitis B PCR positive will be excluded.
  • Patients who are hepatitis C antibody positive will need to have a negative PCR result before randomization. Those who are hepatitis C PCR positive will be excluded.
• History of clinically relevant bleeding diathesis (e.g., hemophilia, von Willebrand disease).
• Current life-threatening illness, medical condition, organ system dysfunction, social, geographical or economic condition which, in the Investigator's opinion, could compromise the patient's safety or put the study at risk.

Laborértékek

• Significant cardiovascular disease such as symptomatic arrhythmias, congestive heart failure, or myocardial infarction within 6 months of randomization or any Class 3 or 4 cardiac disease as defined by the New York Heart Association Functional Classification, or LVEF < 40%.

• History of prior malignancy that could affect compliance with the protocol or interpretation of results, except for the following:
  • Curatively treated localised basal cell carcinoma or localised squamous cell carcinoma of the skin or carcinoma in situ of the cervix or carcinoma in situ / low risk carcinoma of the prostate requiring only observation, as well as untreated low grade lymphoma except chronic lymphocytic leukemia.
  • Other cancers not specified above that have been curatively treated by surgery and/or radiation therapy from which patient is disease-free for ≥2 years (≥5 years for those treated with chemotherapy) without further treatment or which are not expected to limit survival to < 2 years.
