Primary objective:1. To compare the change from baseline of the Area under the curve (AUC) of tamoxifen in patients with breast cancer treated with tamoxifen with and without green tea supplements.Secondary objectives:1. To compare the Area under…
• To evaluate the effect of olaparib on exposure to anastrozole by determination of steady-state exposure to anastrozole in the presence and absence of steady-state exposure to olaparib• To evaluate the effect of anastrozole on exposure to olaparib…
The main objective is: To determine the influence of curcumin with or without piperine, in patients with breast cancer, on endoxifen plasma pharmacokinetics (AUC).Secundary objectives are:1. Other pharmacokinetic outcomes (i.e. clearance, minimum…
Inhibition of CYP2D6 enzymes by SSRIs may lead to reduced endoxifen plasma concentrations and thereby possibly influence tamoxifen treatment outcome. Paroxetine is a potent CYP2D6 inhibitor and strongly reduces endoxifen plasma concentrations.…
- To evaluate the effect of steady-state TMC278 25 mg q.d. on the steady-state pharmacokinetics of R- and S-methadone.- To evaluate the potential effect of TMC278 on the pharmacodynamic effects of methadone therapy; - To evaluate the steady state…
The primary objective of the trial is to demonstrate non-inferiority of treatment with TMC278 when administered as 75 mg q.d. compared to the control group (EFV) in regard to the proportion of virologic responders (plasma viral load < 50 HIV-…
This study involves research and the objective of this study is to evaluate how much and how fast TMC278 is absorbed into the body after administration as these concept pediatric formulations compared to when administered as the 25 mg TMC278 tablet…
This trial studies the effects on quality of life and on time to second progression of the sequence endocrine therapy-capecitabine versus the sequence capecitabine-endocrine treatment. It is anticipated that the time on study (which is the time…
To determine the influence of morning versus evening administration on the pharmacokinetics of tamoxifen and its metabolites. Amendment: To determine the influence of time of administration (morning (8 a.m.), afternoon (1 p.m.) and evening (8 p.m…
- To examine the effects of cytochrome P450 induction by rifampicin on the metabolism and pharmacokinetics of tamoxifen and its metabolites. Induction of cytochrome P450 enzyme expression (including CYP3A4, CYP2C and CYP2D6) by rifampicin will…
To evaluate the safety, including tolerability, of ISIS 681257 and to assess the efficacy of different doses and dosing regimens of ISIS 681257 for reduction of plasma Lp(a) levels in patients with hyperlipoproteinemia(a) and established CVD.To…
To evaluate the effects of COS with tamoxifen or letrozole compared to standard COS, on oocytes retrieved.
To determine the influence of concomitant administration of tamoxifen and probenecid on tamoxifen and endoxifen(-glucuronide) plasma concentrations
To compare the plasma concentration of edoxaban in women with breast cancer before and during treatment with tamoxifen.
Primary Objective1. To prove that TDM of tamoxifen is feasible in clinical practice. Secondary Objectives1. To determine the relation between the pharmacokinetics (PK) of tamoxifen and its metabolites and relevant adverse effects.2. To investigate…
