             within 3 months of screening, up to and including Day 1.

          -  Any active medical condition other than asthma, that in the opinion of the

             medical monitor, may compromise the safety of the subject in the study or interfere
             with evaluation of the investigational product or reduce the subject's ability to
             participate in the study.

          -  Evidence of active liver disease,

          -  Positive hepatitis B or hepatitis C virus
