-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…
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…
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 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…
• 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 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 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…
Primary objective is: * To determine the overall survival (OS) benefit of PAG treatment, compared with AG treatment, in subjects with HA-high Stage IV previously untreated PDA.Secundary objectives are:* To determine the PFS benefit of PAG treatment…
The purpose of this study is to test the safety, tolerability and anti-tumor activity of the research study drug, Pembrolizumab (MK-3475) in combination with chemotherapy drugs of physician's choice (which includes Nab-paclitaxel, Paclitaxel or…
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-…
Unless otherwise specified, efficacy objectives will be analyzed for the following two treatment comparisons:• Atezolizumab + carboplatin + nab-paclitaxel (Arm B) versus carboplatin + nab- paclitaxel (Arm C)• Atezolizumab + carboplatin + paclitaxel…
To evaluate the effects of COS with tamoxifen or letrozole compared to standard COS, on oocytes retrieved.
Phase ITo determine the toxicity and optimal dose of LDE225 when co-administered with fixed doses of gemcitabine and nab-paclitaxel in patients with advanced and metastasized pancreatic cancer.Phase IITo determine the anti-tumor activity of LDE225…
Primary:In 1L subjects with metastatic squamous non-small cell lung cancer (NSCLC) receiving investigator*s choice of standard of care chemotherapy (i.e. carboplatin and a taxane):1. Evaluate progression free survival (PFS) per RECIST 1.1 as…
