To Compare Blood and Urine Concentrations of Mirabegron (YM178) in Healthy Poor or Extensive Metabolizers for CYP2D6 and to Assess the Effect of Mirabegron on the Metabolism of Metoprolol
An Open Label, One-sequence, Parallel Study to Compare the Single Dose Pharmacokinetics of YM178 in Healthy Poor or Extensive Metabolisers for CYP2D6 and to Assess the Effect of Multiple Doses of YM178 on the Metabolism of the Model Substrate Metoprolol
調査の概要
詳細な説明
The study is an open label, single center study. All subjects are genotyped for CYP2D6 before the study. Genotype expression is confirmed by dextromethorphan phenotyping.
Part I: The pharmacokinetic profile of a single dose of YM178 is compared in 8 healthy male subjects genotyped and phenotyped as poor metaboliser (PM) for CYP2D6 and in 8 healthy male subjects genotyped and phenotyped as extensive metaboliser (EM) for CYP2D6.
Part II: The effect of YM178 on the model substrate of CYP2D6 metoprolol is evaluated, using a cross-over design, in 12 healthy male subjects genotyped and phenotyped as EM for CYP2D6.
