It is general that there are many factors for individual differences of drugs in clinical application, of which genetic factors accounted for more than 20%. Novel oral anticoagulants-NOACs (include rivaroxaban, apixaban, dabigatran and so on) have advantages of convenient use and no need of monitoring, compared with the traditional vitamin K antagonist. With lack of predicted biomarkers, especially the research data of Chinese, it has the important significance in studying individual differences of NOACs in the anticoagulant efficacy and safety, through the pharmacogenomics research. The aim of this study is to determine the polymorphism of drug metabolizing enzymes, drug transporters and drug target genes in Chinese population. By detecting the gene polymorphism, we intend to study the pharmacokinetic/ pharmacodynamics/ pharmacogenomics (PK-PD-PG) correlation of NOACs and provide scientific basis for accurate medication guide for people to use NOACs.
It is general that there are many factors for individual differences of drugs in clinical application, of which genetic factors accounted for more than 20%. Ticagrelor is a new-type receptor antagonist of P2Y12 and it is not affected by the influence of CYP2C19 polymorphism. With lack of predicted biomarkers, especially the research data of Chinese, it has the important significance in studying individual differences of ticagrelor in the antiplatelet efficacy and safety, through the pharmacogenomics research. The aim of this study is to determine the polymorphism of drug metabolizing enzymes, drug transporters and drug target genes in Chinese population. By detecting the gene polymorphism, we intend to study the pharmacokinetic/ pharmacodynamics/ pharmacogenomics (PK-PD-PG) correlation of ticagrelor and provide scientific basis for accurate medication guide for people to use ticagrelor.
This study will assess whether exposure response analysis of the electrocardiographic QTc and J-Tpeakc intervals in Phase 1 clinical pharmacology studies can be used to confirm that drugs that predominantly block the potassium channel encoded by the human ether-à-go-go-related gene (hERG) with approximately equipotent late sodium and/or calcium block ("balanced ion channel" drugs) do not cause J-Tpeakc prolongation and that drugs that predominantly block hERG without late sodium or L-type calcium current block ("predominant hERG" drugs) cause QTc prolongation.
This is a Phase I, Randomized, Single-Blind, Crossover Study to Assess the Pharmacodynamics of AZD9977 following Single-Dose administration to healthy male subjects
This is a Phase I, first-in-human (FIH), randomized, single-blind, placebo-controlled, single ascending dose sequential group study in healthy male subjects. The objectives are to study the safety, tolerability, pharmacokinetics and effects on glucose homeostasis (pharmacodynamics) of AZD9567, an oral differentiated non-steroidal selective glucocorticoid receptor modulator (SGRM). The study will also assess the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of prednisolone 60 mg in comparison with high doses of AZD9567 and placebo.
The primary objective of this research study is to test the hypothesis that late sodium current blocking drugs (mexiletine or lidocaine) can attenuate the effect of hERG potassium channel blocking drugs (dofetilide) on ventricular repolarization (QTc) by shortening early repolarization (J-Tpeakc). The secondary object is to assess the ability of calcium channel block (diltiazem) to reduce the QTc prolongation associated with hERG block (moxifloxacin).
Cohorts of Japanese participants will be enrolled and treated prior to cohorts of Caucasian participants for the sake of matching. Every effort will be made to match Caucasian and Japanese participants on a cohort basis at enrollment. Reasonable effort will be made to maintain balance between male and female participants within the cohorts. There will be no replacement of participants following randomization.
The purpose of this study is to evaluate the safety and tolerability of single and multiple oral dosing of MLN3126 in ascending doses in healthy non-Japanese and Japanese participants.
To evaluate the pharmacodynamics of a lower Ticagrelor dose in healthy Korean volunteers compared with standard Clopidogrel agent.
