- 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…
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 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.…
• 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…
Primary: efficacy and safety of the addition of UMEC 62.5mcg once daily to ICS/LABA therapy, compared with placebo over 12 weeks in subjects with COPD.Secondary: effect of the addition of UMEC to ICS/LABA therapy on COPD-related health status…
To evaluate the effects of COS with tamoxifen or letrozole compared to standard COS, on oocytes retrieved.
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:To compare the effect of UMEC/VI (62.5/25 mcg once daily) with UMEC (62.5 mcg once daily) on lung functionSecondary:To compare UMEC/VI, UMEC with salmeterol (50 mcg twice daily) on patient reported outcomes and on other COPD efficacy…
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
To compare the plasma concentration of edoxaban in women with breast cancer before and during treatment with 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…
Primary:To demonstrate the non-inferior antiviral activity of CAB LA + RPV LA every two months compared to a BIK single tablet regimen administered once daily over 12 months in suppressed HIV-1 infected antiretroviral therapy (ART)-experienced…
In phase I safety and pharmacological properties of GDC-0032 in combination with tamoxifen in patients with advanced solid tumors will be investigated. The effectiveness of GDC-0032 in combination with tamoxifen will be studied in patients with…
