E.4 | Principal exclusion criteria |
1. Any clinically relevant abnormality identified on the screening medical assessment, laboratory examination (e.g. haematology parameter outside the normal limits), or ECG (12 Lead or Holter). 2. Subject has a positive Hepatitis B surface antigen or Hepatitis C antibody result at screening. 3. Subject has a history of elevated liver function tests on more than one occasion (ALT, AST and ALP > 3 x Upper Limit of Normal (ULN); total bilirubin > 1.5 x ULN) in the past 6 months. 4. Previous exposure or past infection caused by Mycobacterium tuberculosis 5. Subject has an acute infection. 6. Subject has a history of repeated, chronic or opportunistic infections that, in the opinion of the investigator and/or GSK medical monitor, places the subject at an unacceptable risk as a participant in this trial. 7.

Subject has a history of human immunodeficiency virus (HIV) or other immunodeficiency disease. 9. Subject whose calculated creatinine clearance is less than 50ml/min 10.
