- Patients who in the investigator's judgment are likely to need psychotropic medications apart from the drug. Patients who at any time during Study Period II are likely to begin a structured psychotherapy, likely to require hospitalization (i.e. in-patient treatment) or likely to be dismissed from in-patient treatment. Psychotherapy (including hospitalization) initiated at least 2 months prior to study participation is acceptable; however, after study participation has begun, only during Study Period III supportive or educational therapy is permitted.
