        Exclusion criteria:

             normal and judged as clinically relevant by the investigator

          -  Any laboratory value outside the reference range that the investigator considers to be
             of clinical relevance

          -  Any evidence of a concomitant disease judged as clinically relevant by the
             investigator

          -  Gastrointestinal, hepatic, renal, respiratory, cardiovascular, metabolic,
             immunological or hormonal disorders

             T-SPOT) test may participate in the study if further work up (according to local
             practice/guidelines) establishes conclusively that the subject has no evidence of
             active tuberculosis. If presence of latent tuberculosis is established, then treatment
             must have been initiated and maintained according to local country guidelines.

             medication or its excipients)

             reasonably influence the results of the trial or that might prolong the QT/QTc
             interval

          -  Participation in another trial (including bioequivalence trial) with an
             investigational drug within 90 days or 5 half-lives (whichever is greater) prior to

             administration of trial medication or during the trial

          -  Inability to comply with dietary regimen of trial site

          -  A marked baseline prolongation of QT/QTc interval (such as QTc intervals that are
             repeatedly greater than 450 ms) or any other relevant ECG finding at screening

          -  A history of additional risk factors for Torsades de Pointes (such as heart failure,

          -  Male patients who do not agree to minimize the risk of female partners becoming
             pregnant from at least 30 days before the first administration of trial medication and
             until 30 days after trial completion.

          -  Subject is assessed as unsuitable for inclusion by the investigator, for instance,
             because considered not able to understand and comply with study requirements, or has a
             condition that would not allow safe participation in the study
