- 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 primary objective of the ERY-PAO study is to investigate the pharmacokinetics of acetylsalicylic acid (ASA) and omeprazole in morbidly obese subjects before and after RYGB surgery and to compare these data to study if there are differences in…
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…
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 objectiveTo determine the effect of multiple dose OME on the pharmacokinetics (AUC0-8h, Cmax, C8h) of BOC.Secondary objectives:To determine the effect of steady state BOC on the pharmacokinetics (AUC0-8h, Cmax, C8h) of multiple dose OME.To…
Primary: To evaluate the efficacy of retigabine as adjunctive therapy to each of the following specified monotherapy AED treatments: carbamazepine/ oxcarbazepine, lamotrigine, levetiracetam or valproic acid in subjects with partial-onset seizures (…
Primary: Long-term safety and tolerability.Secondary: Long-term efficacy.
Primary:to examine the effect of co-administration with omeprazole on the pharmacokinetics of SSP-002358.Secondary:to provide additional safety information for SSP-002358 when administered alone or in combination with omeprazole.
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…
Objective 1: To investigate the difference in prescribing proton pump inhibitors continuously rather than on demand in patient reported reflux symptoms, quality of life and self-rated health. Objective 2: To investigate whether the use of electronic…
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 compare invasive disease-free survival (iDFS) for ribociclib + ET versus placebo + ET in patients with HR-positive, HER2-negative, EBCwith high risk of recurrence.
Phase I study to investigate safety of the combination indomethacin and two platinum-based chemotherapy regimens in patients with advanced cancers.
To determine the influence of concomitant administration of tamoxifen and probenecid on tamoxifen and endoxifen(-glucuronide) plasma concentrations
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-…
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 evaluate the effects of COS with tamoxifen or letrozole compared to standard COS, on oocytes retrieved.
