Clinical Trial Summary

The purpose of this study is to gather information about the steady-state plasma concentrations of aripiprazole, olanzapine, quetiapine and their relevant metabolites, at various dose levels and at different time points after dosing. In addition, comparison of capillary drug concentrations vs. venous drug concentrations will be performed for aripiprazole, olanzapine, paliperidone, quetiapine, risperidone and their relevant metabolites.


Clinical Trial Description

This is an open-label (physicians and participants know the identity of the assigned treatment), parallel-group, multiple-dose, multicenter study to assess pharmacokinetics (what the body does to the medication) of five antipsychotics (APS) drugs: aripiprazole, olanzapine, paliperidone, quetiapine and risperidone in psychiatric participants who are receiving stable doses of these drugs for the treatment of their disease.

Pharmacokinetics data will be generated from venous and fingerstick-based capillary plasma concentrations of the drugs and their metabolites. The total number of enrolled participants in this study will be at least 265. Seventy-five participants will be enrolled for the aripiprazole, olanzapine and quetiapine cohorts (groups) each, and 20 participants will be enrolled for the paliperidone and risperidone cohorts each. In aripiprazole, olanzapine and quetiapine cohorts there will be two subgroups. Subgroup one, 20 participants for fingerstick capillary + venous blood sampling and subgroup two, 55 participants for only venous sampling. Paliperidone and risperidone cohorts will be subjected only to capillary + venous blood sampling.

The study will consist of a screening phase (within 21 days before Day 1) followed by a 3-day observation phase (Day 1 to Day 3). Participants will be admitted to the study center in the evening of Day -1 and will remain in the study center until discharged on Day 3 after completion of the last study-related procedure. During the observation phase, the administration of the prior antipsychotic medication will continue at a participant's usual dose and dosing schedule, under direct observation of the study staff. There will be no modification of the participant's medication during the study. Safety will be evaluated throughout the study and a mandatory pharmacogenomic blood sample will be collected for analysis of genes that may influence exposure of the APS studied. ;
