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.

PANSS rates severity of psychopathology in schizophrenics. 7 items measure positive symptoms (eg. delusions, hallucinations), 7 items measure negative symptoms (eg. blunted affect, social withdrawal), 16 items form a General Psychopathology scale (eg.anxiety, motor retardation). Each item is scored on a 7-point severity scale: 1=absent, 2=minimal, 3=mild, 4=moderate, 5=moderate severe, 6=severe, 7=extreme. Total scores range from 30 to 210. The data here represents the change in total score from baseline to week 1 and higher (positive) scores indicate more severe pathology.

Each item is scored on a 7-point severity scale: 1=absent, 2=minimal, 3=mild, 4=moderate, 5=moderate severe, 6=severe, 7=extreme. Scores may range from 4 to 28. The data presented here represents the change from baseline to week 1. Higher (positive) scores indicate worsening.

CNSVitalSigns cognitive battery consists of 4 tests (Verbal Memory, Symbol-Digit Coding Test, Shifting Attention Test, Continuous Performance Test [CPT]). With Verbal Memory Test, patient asked to remember 15 words within a field of 15 distractors immediately and after twenty minute delay. Score is the sum of correct immediate "hits", correct immediate "passes", correct delayed "hits", and correct delayed "passes". Total score may range from 0 to 60, with a higher score indicating more correct responses. Data represents change from baseline to endpoint, with positive score showing improvement.

The Simpson-Angus EPS Scale is a clinician-rated scale to assess parkinsonian and extrapyramidal symptoms (10 items) associated with antipsychotic medications. Each item is rated on a 5-point scale. In addition, this scale was used to evaluate and characterize adverse events of extrapyramidal symptoms. Total scores are calculated by summing the scores of each item (minimum 0, maximum 40) and dividing by the number of items (10). Scores can range from 0-4. A higher score indicates more severe symptoms. Data represents change from baseline to endpoint, positive values represent worsening.

The C-SSRS was performed at weeks 8, 16, and 24 (or last observation after baseline), and at any time if clinically indicated. The C-SSRS is a clinician-rated scale that assesses suicidality from ideation to behaviors and monitors the potential emergence of suicidality in clinical studies. The data presented here represents the percentage of patients in each arm found to have suicidal behavior in the judgment of a clinician and based upon a clinicians interpretation of the subject's responses to the C-SSRS questions.

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.
