Study summary

The primary objective of this study is to evaluate change in weight as a result of switching from quetiapine to ziprasidone, in subjects with schizophrenia or schizoaffective disorder who have failed to achieve a satisfactory clinical response to quetiapine due to lack of efficacy or poor tolerability.

  7. Change From Baseline in Abnormal Involuntary Movement Scale (AIMS) Total Score, Global Severity Score, and Global Incapacitation Score at Week 16

    AIMS: a 12-item clinician administered instrument assessing observed abnormal movements in different parts of body. Ten items scored on a 5-point scale (0 = none/normal, 4 = severe) evaluate abnormal movements in three main anatomic areas (orofacial area, extremities, and trunk). Two items are yes/no questions regarding dentures. Total scores range from 0 to 42. Item 8 indicates severity, item 9 indicates Incapacitation. AIMS total, global severity, or global incapacitation score: Change = score at Week 16 minus score at Baseline.

    Time frame: Baseline, Week 16

  8. Change From Baseline in Positive and Negative Symptoms of Schizophrenia (PANSS) Total Score, and Positive and Negative Subscale Scores at Week 16

    PANSS measures severity of psychopathology in subjects with schizophrenia, schizoaffective disorder and other psychotic disorders. It includes 3 scales and a total of 30 items: 7 items comprise the positive scale, 7 comprise the negative scale, and 16 items measure general psychopathology. Each item is rated on a scale from 1 (symptom not present) to 7 (symptoms extremely severe). The sum of the 30 items is defined as the PANSS total score and ranges from 30 to 210.

    Time frame: Baseline, Week 16, Week 16 LOCF

  9. Change From Baseline in Clinical Global Impression Severity Scale (CGI-S) at Week 16

    The CGI-S is a single item, clinician-rated scale that assesses the global severity of the subject's overall illness. The CGI-S ratings range from 1 (normal, not at all ill) to 7 (among the most severely ill subjects). CGI-S score: Change: score at Week 16 or Week 16 LOCF minus score at Baseline.

Possible CGI-I scores range from 1 (very much improved) to 4 (no change) to 7 (very much worse).

    Time frame: Week 16, Week 16 LOCF

  11. Change From Baseline in Calgary Depression Scale for Schizophrenia (CDSS) Total Score at Week 16

    The CDSS is a 9-item, clinician-rated scale validated for rating the severity of depressive symptoms in subjects diagnosed with schizophrenia, and independent of confounding negative and extrapyramidal symptoms. The CDSS rates the severity of depressive symptoms on a 4-point scale ranging from 0 (absent) to 3 (severe). The CDSS depression total score is obtained by adding each of the item scores. Total possible score ranges from 0 to 27. CDSS possible total score: Change: score at Week 16 or Week 16 LOCF minus score at Baseline.

    Time frame: Baseline, Week 16, Week 16 LOCF

  12. Change From Baseline in Schizophrenia Cognition Rating Scale (SCoRS) Total Score and Global Rating at Week 16

    The SCoRS is a 20-question rating scale completed via interviews with the subject and an informant, focusing on cognitive impairment and its impact on daily functioning. Each question was completed using a 4-point scale (ranging from 1=none to 4=severe). Total possible score ranged from 20 to 80. At the end of the 20 questions, the interviewer completed a Global Scale of 1-10, rating subject's overall difficulty. Higher scores on both indicated greater cognitive impairment. SCoRS total score and global rating: Change: score at Week 16 or Week 16 LOCF minus score at Baseline.

    Time frame: Baseline, Week 16, Week 16 LOCF

  13. Change From Baseline in Global Assessment of Function Scale (GAF) Score at Week 16

Total possible score ranges from 0 (not enough information available to provide GAF) to 100 (Superior functioning in a wide range of activities, life's problems never seem to get out of hand, is sought out by others because of his or her many qualities. No symptoms). The assessment was done by a trained assessor. GAF scale score: Change: score at Week 16 or Week 16 LOCF minus score at Baseline.

  14. Change From Baseline in Treatment Satisfaction Questionnaire for Medication (TQSM) Effectiveness, Side Effect, Convenience, and Global Satisfaction Subscales at Week 16

    The TSQM is a 13-item subject-rated scale that evaluates the effectiveness, side effects and convenience of the medication over the past 2-3 weeks. Likert scale: 1=Extremely Dissatisfied, 2=Very Dissatisfied, 3=Somewhat Dissatisfied, 4=Neither Satisfied Nor Dissatisfied, 5=Somewhat Satisfied, 6=Very Satisfied, 7=Extremely Satisfied. Worst value is 0 and best value is 100. TSQM Effectivenss, Side Effect, Convenience, and Global Satisfaction scores: Change: score at Week 16 or Week 16 LOCF minus score at Baseline.
