描述(由申请人提供):本修订的主要目标
申请(MH64173),它是抗精神病临床试验的辅助药物
干预有效性(CATIE)的关键是可靠地捕获集中度
抗精神病药物(利培酮、奥氮平、齐拉西酮、
氟奋乃静、奋乃静和氯氮平)使用混合效应群体
药代动力学方法学。群体药动学方法是
非常适合分析来自大型临床的药物浓度数据
干预试验是因为特定患者和总体人群
只需少量血浆样本即可确定药代动力学参数
每个病人。了解药代动力学的可变性对于
合理用药。人口药代动力学方法将允许

英文摘要
DESCRIPTION (provided by applicant): The primary goal of this revised
application (MH64173), which is ancillary to the Clinical Antipsychotic Trials
of Intervention Effectiveness (CATIE), is to reliably capture the concentration
exposure of the antipsychotics (risperidone, olanzapine, ziprasidone,
fluphenazine, perphenazine, and clozapine) using mixed effect population
pharmacokinetic methodologies. The population pharmacokinetic approach is
ideally suited for analyzing drug concentration data from large clinical
intervention trials because patient-specific as well as overall population
pharmacokinetic parameters can be determined using only a few plasma samples
per patient. An understanding of pharmacokinetic variability is essential to
rational drug prescribing. The population pharmacokinetic approach will permit
determination of the extent of variability in drug exposure associated with the
use of atypical antipsychotics in large populations under conditions that
mirror clinical practice. In addition, the ability of population
pharmacokinetic models to capture subjects' drug exposure utilizing single
concentration measurements will be assessed in this study. Population
pharmacokinetics has also been successfully used to identify sources of
variability in drug concentration exposure. Therefore, this ancillary study
will provide an innovative way to make optimal use of plasma samples that are
being obtained in the CATIE trials. The CATIE trials will recruit up to 2,250
patients providing from 1 to 6 plasma concentration samples per subject for
each medication. A separate population pharmacokinetic model will be
constructed for each drug incorporating covariate effects. Specific covariates
will be then be evaluated as potential contributors to drug exposure
variability. Demographic covariates to be examined are age, sex, race/minority
status, and body mass index. The potential impact of additional covariates such
as prior medication exposure, concomitant medications, smoking status,
estimated renal clearance, and treatment adherence will also be assessed. By
providing pharmacokinetic data on the atypical antipsychotics under "real
world" conditions, this study has broad public health implications, leading to
greater awareness of the need to individualize antipsychotics pharmacotherapy
for patients suffering from either schizophrenia or Alzheimer's disease.
