- Clinical or laboratory evidence of significantly decreased hepatic function or decompensation: INR \> 1.5 or albumin \< 30g/L or bilirubin \> 2.5 x ULN
- Resolution of their CNS toxicity between Screening and Baseline visits
- Any condition (including drug/alcohol abuse) or laboratory results which, in the investigator's opinion, interfere with assessments or completion of the trial.
