E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study is to assess whether LY2140023, when administered in an acute-treatment trial with flexible doses (40 or 80 mg) BID is associated with physical dependence, as measured by the occurrence of withdrawal symptoms during a randomized withdrawal phase in patients diagnosed with schizophrenia. |
|
E.2.2 | Secondary objectives of the trial |
•To characterize the symptoms observed in randomized patients treated with LY2140023 compared with those on placebo during the withdrawal phase using Rickels checklist
•To evaluate symptoms in randomized patients treated with LY2140023 compared with those on placebo during the withdrawal phase using the CIWA-Ar scale
•To evaluate the safety and tolerability of randomized LY2140023 compared with placebo during the withdrawal phase
•To assess the safety and tolerability of randomized LY2140023 during the open-label treatment phase
•To assess the efficacy of randomized LY2140023 compared with placebo during the withdrawal phase using the CGI-S and BPRS scales
•To assess whether LY2140023, when administered in flexible doses, is associated with physical dependence within a prospectively defined subpopulation.

•Prolactin level at Visit 1 of >200 ng/mL (>200μg/L), with the exception of patients presently treated with risperidone. Patients treated with risperidone prior to study screening are excluded if their prolactin level is >300 ng/mL (>300μg/L) at Visit 1.
•Patients with a corrected QT interval (Bazett’s; QTcB) >450 milliseconds (msec) (male) or >470 msec (female) at Visit 1 (based on the central vendor’s ECG overread)
•Are incapable of participating in the study (for example, those whose physical condition makes them unable to participate fully) or are unwilling to engage in a meaningful way as study participants (for example, patients who are unresponsive or uncooperative with investigators or site personnel).
