6.Patients having Clinical Global Impression scale score of � 4 at both screening and Baseline visits.
7.Patients not having any significant diseases or clinically significant abnormal findings except schizophrenia during screening
8.Adequate organ and bone marrow function at screening and randomization defined by: Bone marrow function:
