Filter by:1. The plasma concentrations of agomelatine and its two metabolites are simultaneously determined by High performance liquid chromatography-tandem mass spectrometry; 2. The gene polymorphisms of CYP1A2, ABCB1 and CYP2C9 are detected by fluorescence in situ hybridization or fluorescence polymerase chain reaction; 3. The correlation of CYP1A2, ABCB1, CYP2C9 gene polymorphisms with the blood concentration of agomelatine and its two metabolites is investigated by pharmacokinetic study; 4. According to the correlation between the above genotypes and blood drug concentration, a lean medication guidance scheme for agomelatine will be formed.
1. To explore the relationship between the changes of plasma concentration of abiraterone acetate after taken orally on fasting or postprandial and gene polymorphism. 2. Study of drug Metabolite profiling after oral administration of abiraterone acetate on fasting and postprandial in Chinese adults.
For patients of GIST (Gastrointestinal Stromal Tumor), Imatinib has been widely used in GIST with KIT or PDGFRA sensitive mutations. From clinical points of view, individual differences often occur between different patients, leading diverse effect in ADR and drug effect. Meanwhile, the drug effect and adverse drug reaction was significantly influenced by the pharmacokinetic factors and pharmacodynamic and other factors. In this research, we try to establish a more sensitive method to detect sensitive mutations in plasma and discover the correlation between somatic and germline mutations, plasma trough concentration and drug effect, the association between ADME-associated SNP, Target/Receptor/Pathway-associated SNP, trough concentration and TKI adverse effect. Furthermore, in vivo and in vitro research is also crucial for rational explanation for these clinical phenomenon.
This is an open-label, randomised, 4-way crossover study in twelve healthy male volunteers. The study will characterise the performance of IntelliCap® by evaluating the plasma concentration and pharmacokinetic profile of a probe drug (IMP; metoprolol) released from IntelliCap® with three different release profiles and the plasma concentration and pharmacokinetic profile of the same probe drug after a single dose of an oral solution.
