E.4 | Principal exclusion criteria |

Treatment with any investigational agent within 4 weeks (or 5 half-lives of the investigational drug, whichever is longer) of screening 5. Have screening electrocardiogram (ECG) abnormalities that, in the opinion of the investigator, are clinically significant and indicate an unacceptable risk for the patient´s participation in the study. 6. Have experienced any of the following VTE (DVT/pulmonary embolism, myocardial infarction, unstable ischemic heart disease stroke, or New York Heart Association Stage III/IV heart failure within 12 weeks of screening. For Centres within Czech Republic patients with any history of it must not be included. 7. Have a history of recurrent (≥ 2) VTE (DVT/PE) 8. Have a history or presence of cardiovascular, respiratory, hepatic, gastrointestinal, endocrine, hematological, neurological, or neuropsychiatric disorders or any other serious and/or unstable illness that in the opinion of the investigator could constitute an unacceptable risk when taking investigational product or interfere with the interpretation of data 9. Immunization with a live/attenuated vaccine within 12 weeks prior to baseline or are expected to need/receive a live vaccine during the course of the study (with the exception of herpes zoster vaccination at the discretion of the investigator) 10.

Patients who are receiving thyroxine as replacement therapy may participate in the study, provided stable therapy has been administered for ≥ 12 weeks and TSH is within the laboratory´s range. Patients who have TSH marginally outside the laboratory´s normal reference range and are receiving stable thyroxine replacement therapy may participate if the treating physician has documented that the thyroxine replacement therapy is adequate for the patient 13.

Thrombocytopenia (platelets <100,000 cells/μL) (<100 x 103/μL or <100 GI/L) i. eGFR <60 mL/min/1.73 m2 (Bedside Schwartz formula 2009) In the case of any of the aforementioned laboratory abnormalities, the test may be repeated once by the central laboratory during screening and values resulting from repeat testing may be accepted for enrolment eligibility if they meet the eligibility criterion 14. Have a current or recent (< 4 weeks prior to randomization) clinically serious viral, bacterial, fungal or parasitic infection or any other active or recent infection, that in the opinion of the investigator would pose an unacceptable risk to the patient if participating in the study 15. Have a symptomatic herpes simplex at the time of randomization 16. Have had symptomatic herpes zoster infection within 12 weeks prior to randomization 17. Have a history of disseminated/complicated herpes zoster (for example, multidermatomal involvement, ophthalmic zoster, CNS involvement, or post-herpetic neuralgia) 18. Have serologic evidence of current or past Hepatitis B, or Hepatitis C 19. Have evidence of HIV infection and/or positive HIV antibodies 20.

Pregnant women or nursing (breast feeding) mothers 27. Patients with reproductive potential not willing to use an effective method of contraception 28. Have a history of intravenous drug abuse, other illicit drug abuse, or chronic alcohol abuse within the 2 years prior to screening or are concurrently using, or expected to use during the study, illicit drugs (including marijuana) 29.
