[8]Has a history of chronic alcohol or drug abuse or dependence (using
DSM-IV TR criteria) within the past 5 years
[9]Requires the use of concomitant medications that prolong the QT/QTc
interval or has a known history of Long QT Syndrome or Brugada

Visit 2 (baseline value) that, in the opinion of the investigator, are
clinically significant with regard to the patient’s participation in the
study; or has a QTc abnormality at Visit 1 or predose Visit 2 (baseline
value) as indicated by a mean QTc interval >458 ms if male or
>474 ms if female (calculate QTc using Bazett’s correction method;
see Section 6.3.2.2 for details on use of QTc for exclusion).
[10]Has evidence of significant active cardiac disease, uncontrolled hypertension, uncompensated congestive heart failure, or endocarditis
[11]Has potassium <3.2 mEq/L at Visit 1

[14]Has platelets <75 GI/L at Visit 1

[18]Requires or is expected to require use of excluded drugs during the study, in particular specific calcium-channel blockers, immune modulators, or immunosuppressants that are excluded from use in this t
