There are about 13332 clinical studies being (or have been) conducted in Netherlands. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
A controlled dietary intervention study will be carried out based on the stable isotope method the investigators have developed to quantify both the absorption of beta-carotene and its bioconversion to retinol in oil and in a mixed diet. For 4 weeks the participants will consume 2 capsules/day, 7 days/week with each capsule containing 100-mg [13C10] beta-carotene and 100-mg [13C10] retinyl palmitate. For two weeks they will consume a diet with high levels of beta-carotene in vegetables and fruits and for the other 2 weeks they will consume a diet with low levels of beta-carotene in vegetables and fruits supplemented with an extra amount of beta-carotene in oil. Samples of blood and faeces will be taken. The study hypothesis is that the absorption of beta-carotene in oil in comparison with the absorption of beta-carotene in a mixed diet differs by a factor of 3 to 6. The investigators want to measure the influence of the food matrix of vegetables and fruits on the absorption of beta-carotene in ileostomy patients on a western diet.
In this randomized controlled trial, three contemporary modes for chronic obstructive pulmonary disease (COPD) management in Dutch general practices are compared for costs and effects: - usual general practitioner (GP) care (at patient's initiative); - regular practice nurse review; and - integrated self-management education. All three interventions are based on existing guidelines, materials, and field experiences.
A controlled dietary intervention study will be carried out based on the stable isotope method the investigators have developed to quantify both the absorption of beta-carotene and its bioconversion to retinol in oil and in a mixed diet. For 6 weeks the participants will consume 2 capsules/day, 7 days/week with each capsule containing 50-mg [13C10] beta-carotene and 50-mg [13C10] retinyl palmitate. For three weeks they will consume a diet with high levels of beta-carotene in vegetables and fruits and for the other 3 weeks they will consume a diet with low levels of beta-carotene in vegetables and fruits supplemented with an extra amount of beta-carotene in oil. Samples of blood and faeces will be taken. The study hypothesis is that the absorption of beta-carotene in oil in comparison with the absorption of beta-carotene in a mixed diet differs by a factor of 3 to 6. The investigators want to measure the influence of the food matrix of vegetables and fruits on the absorption of beta-carotene in healthy humans on a western diet.
RATIONALE: Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Vatalanib may stop the growth of tumor cells by blocking blood flow to the tumor. Giving temozolomide and radiation therapy together with vatalanib may kill more tumor cells. PURPOSE: This randomized phase I/II trial is studying the side effects and best dose of vatalanib when given together with temozolomide and radiation therapy and to see how well they work in treating patients with newly diagnosed glioblastoma multiforme.
The primary objective of the study is to evaluate the pharmacokinetic behavior of Suc-HSA after consecutive daily intravenous (i.v.) doses. The secondary objectives are to evaluate the safety and tolerability and the antiretroviral and immunological effects of consecutive daily i.v. doses of Suc-HSA.
This is a randomized multicentre trial of emtricitabine (FTC) versus tenofovir (TDF)/FTC in antiretroviral naive subjects with HIV/HBV co-infection over 48 weeks (Clinical Trial A). Plus, a 12 week viral kinetic substudy comparing a subgroup of patients on Clinical Trial A is being conducted. (Substudy A1)
By this study, the investigators want to test if the value of adjuvant pulse glucocorticoid therapy for pemphigus can be determined by comparing an experimental arm (dexamethasone pulse therapy, prednisolone, and azathioprine) with a control arm (placebo pulse therapy, prednisolone, and azathioprine). The investigators will determine the rate of complete remission with dexamethasone pulse therapy; the time needed for complete remission; and the duration of remission, and compare these data with those of the placebo arm.
The primary purpose of the study is to evaluate long-term safety and tolerability of atrasentan 10 mg in men with hormone refractory prostate cancer.
The Alpha Omega Trial is a randomized, placebo-controlled, double-blind dietary intervention study in 4837 postmyocardial infarction patients in the Netherlands to examine whether incidence of cardiovascular diseases during 40 months of follow-up can be prevented by low doses of omega-3 polyunsaturated fatty acids. The key objectives are: - to examine the effect of low-dose supplementation (400 mg/day) of eicosapentaenoic acid and docosahexaenoic acid on incidence of cardiovascular diseases; and - to examine the effect of low-dose supplementation (2 g/day) of alpha-linolenic acid on incidence of cardiovascular diseases.
This trial is conducted in Asia, Europe, Middle East, North America, Oceania, and South America. The purpose of this study is to evaluate the treatment of Recombinant Factor VIIa (eptacog alfa (activated)) in patients with acute intracerebral bleeding. It is expected that more patients will recover without severe permanent disability after acute treatment with Recombinant Factor VIIa by reducing further intracerebral bleeding.
