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.
This open-label, multicenter, parallel study will evaluate the effect of multiple doses of vemurafenib on the pharmacokinetics of a single dose of phenprocoumon in patients with BRAFV600 mutation-positive metastatic malignancies. Patients will be randomized to receive either treatment A: a single oral dose of phenprocoumon 6 mg on Day 1 (Eligible patients will have the option to continue treatment with vemurafenib as part of an extension study (NCT01739764).), or treatment B: vemurafenib 960 mg orally twice daily on Days 1-29 plus a single oral dose of phenprocoumon 6 mg on Day 22 (with the option to receive vemurafenib in the extension study after completion of pharmacokinetic assessments).
Background Physical as well as psychosocial complaints are frequently present in patients with a neuroendocrine tumor (NET). Adequate information is seen as an essential aspect of supportive care. The aim of the current study is to test the effectiveness of a web-based tailored information and support system targeting patients' information and care needs. Key features of this system are self-screening of physical and psychosocial problems, tailored education on reported problems and self-referral to professional health care. Objective To detect whether a web-based tailored information and support system improves patients' perception and satisfaction of received information. The investigators hypothesize that after having received web-based tailored information and support patients feel more informed and are more satisfied with the received information than when receiving standard care. Study design The present study is a randomized prospective longitudinal experimental multicenter pilot study. In this study, we want to examine the effect sizes on the perception and satisfaction by the patient of received information (primary objective) and secondary objectives after having used web-based tailored information and support. Eligible are newly diagnosed NET-patients (N=40) (diagnosed less than 3 months ago). Patients will be asked to fill out questionnaires at baseline and after 12 weeks, on socio-demographic features (only at baseline), internet use (only at baseline), health care use, patients' perception and satisfaction of received information, distress, quality of life and empowerment (only after 12 weeks). Study population Patients diagnosed with a NET (any type of NET, any phase of disease) who are under treatment at the Department of Medical Oncology in the University Medical Center Groningen or Hospital Medisch Spectrum; twenty will be invited to participate in the study. Intervention During 12 subsequent weeks, a personalized website (with a surname/password) will become available to patients in the experimental group beside the usual standard care. Key features of the website are self-screening, tailored patient education and self-referral. Self-screening will be performed by an online version of the Dutch Distress thermometer (DT) and Problem List (PL). Patients will receive automated feedback on their DT score immediately after test completion together with information regarding problems reported on the PL, options for (self)-help and possibilities for referral to professional care. Contact information will also be available to discuss questions, problems and/or referral needs. Patients may also request a telephone call. Main study endpoint The primary endpoint is to detect an improvement in patients' perception and satisfaction of received information after having received web-based tailored information and support.
The primary aim of this study is to evaluate the effect of the drug N-Acetylcysteine on the frequency of pain in daily life in patients with Sickle Cell Disease (SCD). Pain is an invalidating hallmark of this disease and has a considerable impact on the Quality of Life of patients and the medical health care system. Oxidative stress is hypothesized to play a central role in its pathophysiology. In pilot studies the administration of N-Acetylcysteine (NAC) resulted in a reduction of oxidative stress. Moreover, administration of NAC seemed to decrease hospitalization for painful crises in a small pilot study in patients with SCD. This study will be performed as a multicenter, randomized, controlled trial where patients will be treated with either NAC or placebo for a period of 6 months. The investigators expect that NAC can reduce the frequency of pain in patients with SCD, thereby improving their quality of life and participation in society.
This is a registry study to evaluate the long-term safety and effectiveness of adalimumab in patients with moderately to severely active UC who are treated as recommended in the product label.
Prebiotics are thought to be a potential means to prevent antibiotic-associated diarrhoea because of their ability to stimulate beneficial bacteria. In-vitro results showed a promising recovery of Bifidobacteria combined with an increase of Short Chain Fatty Acids (SCFA) upon Galacto-oligosaccharides (GOS) supplementation to amoxicillin-treated microbiota. As the microbiota is nowadays considered as a key factor in human health, a further understanding of the gut microbiota functioning in-vivo is essential. This understanding of the use of specific prebiotics may possibly be beneficial in the prevention or recovery of antibiotic-disturbed microbiota. As the effects of GOS supplementation on the microbiota composition and activity from healthy adults receiving amoxicillin have never been tested in-vivo, the investigators propose the current study as a proof of principle. Objective: To explore whether the promising effects of GOS supplementation on the composition and activity of gut microbiota from healthy adults as found by in-vitro, can also be observed in-vivo. Study population: 10 healthy men and women volunteers, 18 - 40 yr old
The purpose of this study is to investigate the safety and tolerability of 3 multiple and escalating dose regimens of CG400549 administered orally in healthy volunteers.
Many studies have studied the effect and safety of renal denervation. However, it remains unknown what the exact mechanism behind renal denervation is. It can be hypothesized that a difference in renal blood flow occurs after treatment. In the light of this ignorance, current study will investigate whether renal denervation leads to a difference in renal blood flow after treatment with renal denervation.
PROBIC Rationale: Procalcitonin measurements can reduce the number of blood cultures in the ICU. Objective: The investigators suggest that PCT is a marker for blood stream infection in all patients in the ICU in whom attending physicians/ intensivists order blood culturing in the suspicion of microbial infection. The investigators want to demonstrate that its use for guiding blood culturing is cost-effective and safe compared with blood cultures alone. Study design: Prospective, non- inferiority, multicenter, single-blinded, cluster- randomised cross-over clinical trial. Intervention (if applicable): The intensive care units will be allocated into two groups: a control group (blood culture) and the intervention group (procalcitonin). Main study parameters/endpoints: Safety, expressed as mortality at day 28 and 90, with a mortality difference not exceeding a between groups difference of 10% by non-inferiority analysis. Cost-effectiveness, expressed in euro, calculated by deducting costs of procalcitonin testing from saved blood cultures compared with standard treatment spending on blood cultures in the control group. ICIS Rationale: The aim was to evaluate the Intensive Care Infection Score (ICIS) in predicting microbial infection and its sequelae in critically ill patients in whom attending physicians/ intensivists order blood culturing in the suspicion of microbial infection. Objective: Because of the complexity of the pathophysiology of systemic inflammation it is unlikely that a single parameter will have sufficient diagnostic accuracy for infection. Therefore we will study combining parameters producing a diagnostic score. Study design: Prospective, multicenter, cohort trial. Supplement for the control arm of the ProBIC study. Intervention (if applicable): Blood is drawn for daily routine laboratory measurements and collected in K3EDTA aliqnots. The ICIS score is composed of five blood-cell derived parameters which can be extracted using the same aliqnots. Main study parameters/endpoints: To develop and evaluate a blood- cell derived score to enable the diagnosis of microbial infection, its likelihood, its invasiveness and severity.
Patients with unilateral post-thrombotic obstruction of the iliac tract and or common femoral vein, eligible for stenting are included. Intravenous pressure is measured in both dorsal foot veins and both common femoral veins. Patients are asked to undergo a standardised treadmill test (3.2km/h, 0% slope that increases by 2%/2min, maximum walking time 26 min). Painfree and maximum action radius are noted.
