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 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…
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 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…
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 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…
In this study we will assess these prosocial effects in an objective way i.e. by means of computer tasks and we will investigate the role of two potential mediators and the role of a genotype variant in the mechanism underlying prosocial behavior.…
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 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…
Primary: To determine the safety and tolerability of TCAD administered orally to immunocompromised patients diagnosed with influenza ASecondary: To assess the antiviral effect, the speed of symptom resolution, and the influenza complication rate of…
If proven (cost)effective, without inducing antivral resistance, oseltamivir could have considerable benefits in this setting, although constraints relating to implementation need to be addressed as well. If not (cost)effective if this fragile…
Primary: To assess the antiviral efficacy of triple combination antiviral drug (TCAD) therapy(i.e. amantadine and ribavirin co-administered with oseltamivir) compared to oseltamivirmonotherapy in immunocompromised subjects diagnosed with Influenza…
To evaluate the effects of COS with tamoxifen or letrozole compared to standard COS, on oocytes retrieved.
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 determine the influence of concomitant administration of tamoxifen and probenecid on tamoxifen and endoxifen(-glucuronide) plasma concentrations
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…
The primary objectives of this study are:Part A 1. To characterize the effects of single doses of beta-adrenoceptor (*-AR) agonists CST-101, CST-103 and * AR partial agonist CST-109 on the functional domains of the central nervous system (CNS), as…
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 compare the plasma concentration of edoxaban in women with breast cancer before and during treatment with tamoxifen.
Primary objectives1. To assess the safety of Tam added to Ven. Venetoclax will be dosed at 800 mg once daily. After 2 days of venetoclax, tamoxifen will be orally administrated in a ramp-up phase (2 days 10mg, 2 days 20mg, to a final dose of 40 once…
