To evaluate the effects of COS with tamoxifen or letrozole compared to standard COS, on oocytes retrieved.
The primary purpose of the study is to investigate whether the new 20 mg capsule of Orfadin® (nitisinone) has a similar bioavailability in the body (gives the same concentration in the blood) as two of the marketed capsules of 10 mg. The secundary…
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…
The main aim of this study is to assess hypothesis A, and we will perform an exploratory analysis on hypothesis B.
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 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 primary objective of this study is to show bioequivalence between nitisinone oral suspension and nitisinone capsules.Secondary objectives of this study are:- To assess the effect of food on the bioavailability of nitisinone oral suspension.- To…
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.…
Primary objective: To assess the efficacy of Vigantol oil versus placebo as add-on therapy in subjects with relapsing-RemittingMultiple sclerosis receiving treatment with Rebif.Secondary objective:To assess changes on clinical parametersto assess…
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 compare the plasma concentration of edoxaban in women with breast cancer before and during treatment with tamoxifen.
To determine the influence of concomitant administration of tamoxifen and probenecid on tamoxifen and endoxifen(-glucuronide) plasma concentrations
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…
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…
