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…
The primary objective of this study is to test the hypothesis that discontinuation of antipsychotics does not lead to deterioration in functioning as measured by the ABC.
To study whether rivastigmine added to treatment with haloperidol shortens the duration of delirium in ICU patients and reduces costs.
Observe the adherence rate of antidepressants during pregnancy and secondary exploration of possible factors which contribute to non-adherence
The current study is designed as a first exploration of this model. The hypothesis is that haloperidol will lead to an amelioration of the *psychotomimetic* effects of the THC-challenge.
To evaluate whether preventive treament with haloperidol lowers the risk for delirium in stroke patients with an increased risk for delirium.
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)…
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…
The purpose of this study is to investigate the role of dopamine in learning about sexual reward in healthy females. We suppose that repeated associations between a neutral stimulus and sexual stimulation results, through classical conditioning, in…
The role of dopamine in bias and disengagement, two mechanisms implicated in visuospatial attention.
To gain insight in the role of the dopaminergic system in two components of visuospatial attention, bias and disengagement.
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…
-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…
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…
This study aims to clarify whether the brain dopamine and noradrenaline system underlie the electrocortical responses (event-related potentials) that are sensitive to cues signalling reward and probability, the P200 and P300.
To obtain a nonlinear mixed effects model (NONMEM) describing the population pharmacokinetics of haloperidol in the central (CSF) and peripheral compartment after oral and intravenous injection.
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 compare the plasma concentration of edoxaban in women with breast cancer before and during treatment with tamoxifen.
To test if tamoxifen treatment, compared to placebo, reduces the progression of the disease in 6.5-12 years old ambulant DMD patients by at least 50% (using the MFM D1 subscore as primary clinical endpoint in group A patients).To test if 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…
