Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Change From Baseline in Weight at Week 52 | For each participant, change from baseline in weight was calculated as the Week 52 value minus the baseline value. | Baseline and Week 52 | |
Primary | Change From Baseline in BMI at Week 52 | For each participant, change from baseline in BMI was calculated as the Week 52 value minus the baseline value. | Baseline and Week 52 | |
Primary | Number of Participants With Extrapyramidal Symptoms | This measure reports the overall number of participants with any of a group of adverse events that were defined to represent extrapyramidal symptoms. The number of participants with each of the individual adverse events within this definition is also presented, for terms that occurred in at least one participant. For this measure, all adverse event terms within the Medical Dictionary for Regulatory Activities (MedDRA) Standardized MedDRA Query (SMQ) for "extrapyramidal syndrome" were treated as extrapyramidal symptoms. | Up to 30 days after last dose of study drug (Up to approximately 56 weeks) | |
Primary | Change From Baseline in HbA1c at Week 52 | Blood samples for determination of HbA1c were obtained at baseline and during the study. For each participant, change from baseline in HbA1c at Week 52 was calculated as the Week 52 value minus the baseline value. | Baseline and Week 52 | |
Primary | Change From Baseline in Fasting Glucose at Week 52 | Blood samples for determination of fasting glucose level were obtained at baseline and during the study. For each participant, change from baseline in fasting glucose at Week 52 was calculated as the Week 52 level minus the baseline level. | Baseline and Week 52 | |
Primary | Change From Baseline in Insulin at Week 52 | Blood samples for determination of insulin level were obtained at baseline and during the study. For each participant, change from baseline in insulin at Week 52 was calculated as the Week 52 level minus the baseline level. | Baseline and Week 52 | |
Primary | Change From Baseline in Prolactin at Week 52 | Blood samples for determination of prolactin level were obtained at baseline and during the study. For each participant, change from baseline in prolactin at Week 52 was calculated as the Week 52 level minus the baseline level. | Baseline and Week 52 | |
Primary | Change From Baseline in PANSS Total Score at Week 52 | The PANSS is a 30-item clinician-rated instrument for assessing the symptoms of schizophrenia. It consists of 3 subscales: positive subscale (7 items), negative subscale (7 items), and general psychopathology subscale (16 items). Positive symptoms refer to an excess or distortion of normal mental status (e.g., delusions). Negative symptoms represent a diminution or loss of normal functions (e.g., emotional withdrawal). For each item, symptom severity was rated on a 7-point scale, from 1=absent to 7=extreme. The PANSS total score for each participant was calculated as the sum of the rating assigned to each of the 30 PANSS items, and ranged from 30 to 210 with a higher score indicating greater severity of symptoms. The reported measure is the change from baseline at Week 52 (calculated for a participant as Week 52 value minus baseline value); improvement in symptoms is represented by negative values. | Baseline and Week 52 | |
Primary | Change From Baseline in PANSS Total Score at Final Assessment | The PANSS is a 30-item clinician-rated instrument for assessing the symptoms of schizophrenia. It consists of 3 subscales: positive subscale (7 items), negative subscale (7 items), and general psychopathology subscale (16 items). Positive symptoms refer to an excess or distortion of normal mental status (e.g., delusions). Negative symptoms represent a diminution or loss of normal functions (e.g., emotional withdrawal). For each item, symptom severity was rated on a 7-point scale, from 1=absent to 7=extreme. The PANSS total score for each participant was calculated as the sum of the rating assigned to each of the 30 PANSS items, and ranged from 30 to 210 with a higher score indicating greater severity of symptoms. The reported measure is the change from baseline at the final assessment for a participant (calculated for a participant as final assessment value minus baseline value); improvement in symptoms is represented by negative values. | Baseline up to Week 52 |
