Summary
Schizophrenia is a brain disease. The primary features of schizophrenia are characterized by
Positive symptoms (symptoms that should not be there, inability to think clearly, to
distinguish reality from fantasy i.e., hearing voices) and Negative symptoms (a reduction or
absence of normal behaviors or emotions, i.e., unable to manage emotions, make decisions and
relate to others). Other symptoms include reduced ability to recall and learn new
information, difficulty with problem solving, or maintaining productive employment. The
symptoms of schizophrenia may be due to an imbalance in chemicals in the brain, primarily
dopamine and serotonin, which enables brain cells to communicate with each other.
Asenapine is an investigational drug that may help to correct the imbalance in dopamine and
serotonin. This is a 6 week study to test the efficacy and safety of asenapine and a
comparator agent (olanzapine) in the treatment of patients with schizophrenia. Patients that
complete this trial will have the option of continuing in an additional one year extension
trial.
