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.

Arms:
arm 1: 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. arm 2: 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. arm 3: 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. arm 4: 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.
