Study to Evaluate the Efficacy and Safety of Armodafinil as Adjunctive Therapy in Adults With Schizophrenia

Study Overview
=================
Brief Summary
-----------------
The primary objective of the study is to evaluate whether armodafinil treatment is more effective than placebo as adjunctive therapy to antipsychotic medication in alleviating the negative symptoms of schizophrenia

Detailed Description
-----------------
This study was designed and was powered to evaluate the efficacy and safety of armodafinil treatment at dosages of 150, 200, and 250 mg/day compared with placebo over 24 weeks as an adjunctive therapy to antipsychotic medication (olanzapine, oral risperidone, or paliperidone) in adults with schizophrenia who were clinically stable at study entry. Specifically, the effects of armodafinil treatment on the negative symptoms of schizophrenia were the primary assessment in this study.

The patient is in good health (except for the diagnosis of schizophrenia) as judged by the investigator. Women of childbearing potential (not surgically sterile or 2 years postmenopausal) must use a medically accepted method of contraception and must agree to continue use of this method for the duration of the study and for 30 days after participation in the study. Acceptable methods of contraception include barrier method with spermicide, intrauterine device (IUD), steroidal contraceptive (oral, transdermal, implanted, and injected) in conjunction with a barrier method, or documented abstinence. The patient has a PANSS negative symptom score of 15 or more at the screening and baseline visits. Key Exclusion Criteria: The patient has a severity rating of moderate or worse on any item of the PANSS positive symptom subscale. The patient has any Axis I disorder according to DSM-IV-TR criteria, including schizoaffective disorder, apart from schizophrenia and nicotine dependence, or any Axis II disorder that would interfere with the conduct of the study. The patient has moderate to severe depressive symptoms, as indicated by the CDSS. The patient has current active suicidal ideation, is at imminent risk of self-harm, or has a history of significant suicidal ideation or suicide attempt at any time in the past that causes concern at present. The patient has tardive dyskinesia, akathisia, moderate or worse level of extrapyramidal symptoms, or any other clinically significant movement disorder. The patient has a history of any cutaneous drug reaction or drug hypersensitivity reaction, a history of any clinically significant hypersensitivity reaction, or has a history of multiple clinically relevant allergies. The patient is a pregnant or lactating woman. The patient has previously received modafinil or armodafinil, or the patient has a known sensitivity to any ingredients in the study drug tablets.

| Active Comparator: 150 mg/day armodafinil<br>At the baseline visit, patients were randomly assigned to 1 of 3 armodafinil treatment groups or to the placebo treatment group. Patients took 5 tablets orally each day, once daily in the morning. Study drug was titrated (using blister cards) during the double-blind treatment period starting with 50 mg/day of armodafinil or matching placebo. The dosage of armodafinil or matching placebo tablet was increased, as applicable, by 50 mg/day on days 2, 4, 6, and 8, up to the randomized dosage of 150, 200, or 250 mg/day. Patients remained at their randomized dosage for the duration of the study. | Drug: armodafinil<br>* 150 mg/day armodafinil<br>* Other names: CEP-10953;|
