- 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…
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…
The primary objectives of this study are:- To demonstrate that LCZ696 is superior to individualized medical therapy for comorbidities in reducing NT proBNP from baseline after 12 weeks of treatment in patients with HFpEF.- To demonstrate that LCZ696…
• 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…
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 demonstrate the efficacy of LCZ696 in patients with chronic heart failure with preserved ejection fraction (HF-PEF) by testing the hypothesis that the reduction in NT-proBNP from baseline to study end with LCZ696 is greater than that with…
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…
The primary objective of the study is to evaluate the efficacy of aliskiren, valsartan and a combination of both drugs versus placebo in lowering levels of NT-proBNP in stabilized patients post ACS
The primary objective of this study is to determine the efficacy and safety of different doses of LCZ696 compared to valsartan. In addition, the efficacy and safety of AHU377 as compared to placebo is evaluated.
To evaluate the effects of COS with tamoxifen or letrozole compared to standard COS, on oocytes retrieved.
To evaluate the effects of LCZ696 compared to valsartan on cognitive function over 3 years in patients with HFpEF as assessed by the CogState cognitive assessment battery.
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 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 investigate the effect of the ARB valsartan in comparison to placebo on the occurrence of one of the following items, within 14 days of randomization:1) ICU admission; 2) Mechanical ventilation; 3) Mortality.
The primary objective:To compare LCZ696 to valsartan in reducing the rate of the composite endpoint of cardiovascular death andtotal (first and recurrent) heart failure (HF) hospitalizations, in HF patients (NYHA Class II-IV) with preserved EF (LVEF…
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…
