Subjects with a history of mild, stable depression may be considered provided that a pretreatment assessment (including a depression scale, BDI-II or HADS) of the subject’s affective status supports that the subject is clinically stable. Subjects with a score that is elevated (greater than 29 for BDI-II, 7 for HADS) will require further clinical evaluation for depression prior to inclusion into the study.
