Study of Aripiprazole in Patients With Schizophrenia- Effects on Glucose Metabolism-
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
Fasting Blood Glucose (FBS) Level (if Fasting Blood Glucose Level Was Not Available, Non-fasting Blood Glucose (Non-FBS) Level) [ Time Frame: Prior to the start of administration (Baseline) and Weeks 4, 8, 12, 16, 24, 32, 40, 48, 52, or discontinuation ]
The number of subjects whose FBS level reached or exceeded 126 mg/dL (200 mg/dL, non-FBS level) at least once during the test product administration period as well as the incidence were determined. Also, for 110 mg/dL and above (140 mg/dL, non-FBS level), the number of subjects were determined in the same way.
Secondary Outcome Measures :
HbA1c [ Time Frame: Baseline and Weeks 4, 8, 12, 16, 24, 32, 40, 48, 52, or discontinuation ]
The number of subjects with an HbA1c value of 6.5% or higher were calculated. In addition, for 5.8% and above, the number of subjects were also calculated, in the same way

Patients who have taken antipsychotics for less than 2 years and discontinued them for 12 weeks prior to giving informed consent
Patients recently treated with antipsychotics

Patients who do not have any obvious medial history with antidiabetic agents
Patients with no obvious history of diabetes mellitus recorded in the current charts of the study site at the time of giving informed consent
Patients who have not shown any values for the following parameters that deviate from the standard laboratory values in the current charts of the study site at the time of giving informed consent
Patients whose laboratory values meet all of the following criteria in the clinical laboratory tests conducted after patients give informed consent, just before commencement of study drug administration.
Fasting blood glucose level (FBS) <110mg/dL (If FBS is not available, non-fasting blood glucose level*1 <140mg/dL)
*1 : For cases in which blood sugar measurements include values that cannot be judged as having been obtained in the fasted state.
HbA1c <5.8% Fasting blood glucose is defined as glucose concentrations in plasma samples taken between 5 a.m. and 12 noon after at least eight hours of fasting (including abstinence from snacks and calorie-containing juice, coffee, etc. ). All other blood glucose measurements of are counted random glucose.
