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…
To analyse the effect of preoperative intracutaneous and intraperitoneal instillation of levobupivacaine on postoperative pain after laparoscopic cholecystectomy
-The objective of this study is to determine, whether the use of an perioperative echo guided unilateral TAP block has an superior effect on postoperative pain after open hernia inguinal repair compared to wound infiltration with a long acting local…
- 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 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 goal is to find answer to the question: do epidural injections with corticosteroids in patients with sciatica have a positive effect on pain, absenteeism from work and number of operations compared to standard care (pain medication only).
to compare the analgesic efficacy of levobupivacaine and ropivacaine in patient-controlled epidural analgesia, as assessed by the number of requests for epidural bolus injectionsto compare visual analogue scale (VAS) scores and neural block…
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…
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.…
The objective of this study is to determine, whether the use of an perioperative echo guided unilateral TAP block has an superior effect onpostoperative pain after open hernia inguinal repair compared to wound infiltration with a long acting local…
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…
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…
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…
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 determine the influence of concomitant administration of tamoxifen and probenecid on tamoxifen and endoxifen(-glucuronide) plasma concentrations
The objective of this study is to determine the clinical outcomes of ultrasound guided femoral nerve blockage using intermitting shots of levobupivacaine, in patients with hip fractures and to compare these results with placebo injections.The…
To evaluate the effects of COS with tamoxifen or letrozole compared to standard COS, on oocytes retrieved.
