To evaluate the effects of COS with tamoxifen or letrozole compared to standard COS, on oocytes retrieved.
Primary objective1. To compare the Area under the curve (AUC) of endoxifen in patients with breast cancer treated with tamoxifen with and without diclofenac.Secondary objectives1. To compare the Area under the Curve (AUC) of tamoxifen and endoxifen-…
To evaluate in detail the functionality of immune cells in the liver and blood in chronic HCV patients before, during and after treatment with telaprevir, pegylated-IFN-alfa and ribavirin.
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 optimize DM-BT by addition of multiple breath sampling and improve it for use in clinical practice-To create a population based pharmacokinetic model based on DM-BT predicting endoxifen serum levels-To identify ideal single or two time points…
Primary objective:To show that concomitant use of telaprevir (1125 mg BID) does not lead to a relevant decrease (> 20%) in the paroxetine parameter AUC0-24h compared to paroxetine alone.Secondary objectives:To determine the ratio of the…
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…
To investigate prospectively how the "TAMRO-profile" performs in a pre-operative treatment setting. In addition we can examine whether the profile is specific for tamoxifen or is predictive for endocrine resistance in general. Also the…
• 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…
OBJECTIVES AND HYPOTHESISPrimary ObjectivesThe primary objectives are to determine- the effect of steady-state telaprevir 750 mg every 8 hours (q8h) on the multiple dose pharmacokinetics ofphenytoin 200 mg every 12 hours (q12h) in healthy subjects,…
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.…
This study has two major goals. The first goal of this study is to evaluate whether the disabilitating effects of crowding can be reduced by the use of a magnifier early in life. The second goal is to investigate motor and visual development of…
Primary: To evaluate the effect of a dose increase to 40mg tamoxifen QD for 4 weeks in patients with at least one CYP2D6 variant allele and/or the presence of a CYP2D6 inhibitorSecondary:To evaluate the effect of concomitant use of (potential)…
This study involves research and the objective of this study is to investigate the effect of esomeprzole on the single-dose pharmacokinetics (i.e., how a drug moves through the body) of telaprevir. And to obtain additional data regarding the safety…
To provide access to a telaprevir-based treatment to subjects of the Control Group (Group A) of Study VX06-950-106 who stopped treatment due to inadequate response to treatment (according to treatment stopping rules). Safety, tolerability, and HCV…
The first aim of the study is to investigate the effect of telaprevir on the concentration of LPV/rtv and ATV/rtv in the blood and the effect of LPV/rtv and of ATV/rtv the concentration of telaprevir in the blood.The second aim is to investigate the…
The objective of this trial is to explore the efficacy, safety, tolerability, pharmacokinetics, and pharmacokinetic-pharmacodynamic relationships of telaprevir when administered as 750 mg q8h or 1125 mg q12h in combination with Peg IFN alfa2a (…
To compare to control (Group A) (peginterferon alfa-2a [Peg IFN-*-2a] and ribavirin [RBV] for 48 weeks) the proportion of subjects who achieve sustained viral response (SVR, undetectable HCV RNA 24 weeks after completion of treatment) when given…
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…
