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

PANSS rates severity of psychopathology in schizophrenics. 7 items measure NEGATIVE symptoms: blunted affect, social withdrawal, poor rapport, passive/apathetic social withdrawal, difficulty in abstract thinking, lack of spontaneity and flow of conversation, stereotyped thinking. 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. Negative Scale score ranges from 7-49 (higher more severe). Data represents change in Negative Rating Scale from baseline to endpoint with positive scores indicating more severe pathology.

A sleep questionnaire was used to evaluate the effect of armodafinil treatment on the patient's nighttime sleep. Patients completed the questionnaire to evaluate the sleep latency, duration, nighttime awakenings, and overall sleep quality. The questionnaire was assessed at the screening visit and at weeks 12 and 24 (or last visit after baseline). The data presented here represents the change from baseline to endpoint in reported number of nighttime awakenings. A positive value represents an increase in number of night time awakenings.

Barnes Akathisia Rating Scale (BARS) measures presence and severity of drug-induced akathisia. Items related to objective akathisia, subjective awareness of restlessness, and distress related to restlessness were rated using a 4-point scale: 0=normal/no distress, 1=presence of restlessness/mild distress, 2=observable restlessness/moderate distress, 3=constant restlessness/severe distress. Total score is sum of scores of each item and range from 0-9. Higher score indicates greater restlessness and distress. Data represent change from baseline to endpoint, positive values represent worsening.

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.

Each item is scored on a 7-point scale: 1=absent, 2=minimal, 3=mild, 4=moderate, 5=moderate severe, 6=severe, 7=extreme. Scores range from 8 to 56. Higher (positive) scores indicate worsening.

The 4-Part Continuous Performance Test (CPT) is a component of the CNSVitalSigns cognitive battery. The 4-Part CPT assesses working memory. The patient was presented with targets and had to remember target presentation sequencing in order to respond to the directions. The complexity of the directions increased as the patient proceeded through the 4 parts of the test. Scoring is based on the number of correct responses, with a higher number indicating more correct responses. Data represents change from baseline to week 24 with positive values demonstrating improvement.

PSP is a validated clinician-rated assessment of functioning. Four areas of functioning (socially useful activities, personal/social relationships, self-care, disturbing/aggressive behaviors) are assessed on a 6-point scale (0=absent to 5=very severe). A transformed score from 1 to 100 is generated from the raw score based on the clinical interpretation of the scores generated in the 4 areas of functioning, with a higher transformed score indicating better function. Data presented here represents change from baseline to week 4 in the overall score with positive values signifying improvement.

Time frame: Baseline and Week 4

Population: The number of participants with evaluable data (who completed the assessments at baseline and endpoint) are presented.

PANSS is a clinician-rated instrument that rates the severity of psychopathology in patients with schizophrenia. 7 items measure positive symptoms: delusions, conceptual disorganization, hallucinatory behavior, excitement, grandiosity, suspiciousness/persecution, hostility. 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. The data here represents the change in the Positive scale score from baseline to Week 4. The scale may range from 7 to 49, higher (positive) score indicating more severe pathology.

PANSS rates the severity of psychopathology in patients with schizophrenia. The negative symptoms factor score includes 5 negative symptoms (blunted affect, emotional withdrawal, poor rapport, positive/apathetic social withdrawal, lack of spontaneity) and 2 general psychopathology symptoms (motor retardation, active social avoidance). 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 7 to 49. Higher (positive) score indicates worsening. Data represents change from baseline to week 4.

Population: The number of participants with evaluable data (who completed the assessments at baseline and endpoint) are presented.

PANSS rates severity of psychopathology in patients with schizophrenia. The positive symptoms dimension is sum of 4 positive symptoms (delusions, hallucinatory behavior, grandiosity, suspiciousness/persecution), 1 negative symptom (stereotyped thinking), and 3 general psychopathology symptoms (somatic concern, unusual thought content, lack of judgment/insight). Each item is scored on a 7-point scale: 1=absent, 2=minimal, 3=mild, 4=moderate, 5=moderate severe, 6=severe, 7=extreme. Scores range from 8 to 56. Higher (positive) scores indicate worsening. Data show change from baseline to week 4.

Population: The number of participants with evaluable data (who completed the assessments at baseline and endpoint) are presented.

PANSS rates psychopathology severity in schizophrenics. 16 items form a General Psychopathology scale:somatic concern, anxiety, guilt feeling, tension, mannerisms/posturing, depression, motor retardation, uncooperative, unusual thoughts, disorientation, poor attention, poor judgment/insight, disturbance of volition, poor impulse control, preoccupation, social avoidance. Scored on severity scale: 1=absent, 2=minimal, 3=mild, 4=moderate, 5=moderate severe, 6=severe, 7=extreme. Scores range from 16 to 112, higher (positive) score more severe pathology. Data show change from baseline to week 4.

PANSS is a clinician-rated instrument that rates the severity of psychopathology in patients with schizophrenia. The anxiety/depression dimension is the sum of 4 general psychopathology symptoms (anxiety, guilt feelings, tension, depression). 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 8. Higher (positive) scores indicate worsening.

Time frame: Baseline and Week 8

Population: The number of participants with evaluable data (who completed the assessments at baseline and endpoint) are presented.

PANSS rates severity of psychopathology in schizophrenics. Disorganized thought dimension is the sum of 1 positive symptom (conceptual disorganization), 1 negative symptom (difficulty in abstract thinking), and 5 general psychopathology symptoms (mannerisms and posturing, disorientation, poor attention, disturbance of volition, preoccupation). 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 range from 7 to 49. Higher (positive) score indicates worsening. Data indicates change from baseline to week 8.
