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.
Flavonoid-rich foods such as tea and cocoa have been identified as having a blood pressure-lowering effect. Part of this effect is thought to be due to the flavonoid content of these foods although it is currently unknown which flavonoids play a role. Epicatechin is one the major flavonoids in cocoa while quercetin is largely found in tea. During this study the investigators plan to investigate the effects of pure epicatechin and quercetin supplementation on vascular function and blood pressure in untreated (prehypertensive) subjects by way of a three-armed double-blind crossover intervention. Participants will sequentially consume supplements containing quercetin, epicatechin or placebo for a period of 4 weeks. Before and after this 4 week period, measurements of vascular function and blood pressure will be taken. The investigators hypothesize that the supplementation of epicatechin and quercetin will improve vascular function and blood pressure.
3rd line standard treatment of patients with metastatic colorectal cancer (CRC) harboring K-ras wild type consists of anti-EGFR treatment with either cetuximab or panitumumab. This type of treatment has a modest but significant beneficial activity in this patient group with improved progression-free and overall survival. Although it is well known that patients with advanced CRC harboring a K-Ras mutation will not respond to anti-EGFR treatment, it is not understood why patients with K-Ras wild type CRC do not all benefit from this type of therapy. In order to optimize treatment of these patients as well as health care costs, it is extremely important to identify those patients who will respond to treatment with an EGFR inhibitor at an early stage. The investigators hypothesize that the differences in response to treatment with cetuximab are due to variability in the pharmacokinetics and -dynamics of the antibody. Thus, the investigators hypothesize that patients who do not respond to anti-EGFR treatment, have insufficient drug levels in tumor tissue. The investigators hypothesize that this is due to pharmacodynamic processes such as sequestration of cetuximab in the liver which expresses high levels of EGF receptor. The phase I part of the study was fulfilled after inclusion of 36 patients to evaluate the potential applicability of the 89Zr-cetuximab PET as predictive marker for (absence of) response to cetuximab. Along with this analysis, FDG-PET evaluation before and after 1 administration of cetuximab was being performed. While we observed no correlation of 89Zr-cetuximab tumor uptake with clinical benefit in these 36 patients, we did find a clinical significant predictive value for the absence of response with early 18F-FDG-PET with the lack of clinical benefit at 2 months of treatment in this group of patients. Early 18F-FDG PET response evaluation shows great potential to be a clinically applicable tool to stop an ineffective treatment in a very early phase after one administration of treatment. Such an early predictor is unprecedented in clinical daily practice and will 1) avoid unnecessary toxicity of inactive treatment, 2) will lead to faster prescription of a potentially active alternative treatment and 3) will reduce costs by preventing administration of inactive treatment. In order to provide solid evidence for this new approach, we aim to validate early 18F-FDG-PET as a predictive imaging strategy to identify non-responders in part 2 of the study.
Dendritic cells (DCs) are the professional antigen-presenting cells of the immune system. As such they are currently used in clinical vaccination protocols in cancer patients, and both immunological and clinical responses have been observed. Several subsets of dendritic cells have been characterized in the peripheral blood. One such subset is referred to as plasmacytoid dendritic cells (PDC), another as myeloid dendritic cells (myDC). To date PDC and myDC have not been evaluated for their capability to induce anti-tumor immune responses in patients. For this reason the investigators will perform a safety and efficacy study with PDC and myDC in stage IV melanoma patients.
This study will test the clinical effectiveness and safety of apremilast compared with placebo as well as etanercept compared with placebo in the same group of patients with moderate to severe plaque psoriasis.
The GI MRI Research group at the University of Nottingham has been developing new, non-invasive magnetic resonance imaging (MRI) techniques to image the gastrointestinal tract. In collaboration with food manufacturer Unilever, the investigators want to image the abdomen of healthy volunteers after consumption of test meals of varying volume and energy density to determine levels of gastric distension and investigate possible correlations of this with the subjects' sense of satiety.
To evaluate the efficacy of vemurafenib in combination with cobimetinib (GDC-0973), compared with vemurafenib and placebo, in previously untreated BRAF V600 mutation-positive patients with unresectable locally advanced or metastatic melanoma, as measured by progression-free survival (PFS), assessed by the study site investigator.
A new paediatric formulation (oral liquid) has been developed for flexible and accurate dosing of valacyclovir in children. To establish the bioavailability of this new formulation, healthy volunteers will be exposed to the new formulation and to valacyclovir tablets. The concentration of valacyclovir in their blood after exposure to the oral liquid will be measured and compared to the tablet.
The purpose of this study is to determine the safety and efficacy of TRx0237 in the treatment of subjects with mild Alzheimer's Disease.
The purpose of the ACCELERATE study is to evaluate the efficacy and safety of evacetrapib in participants with high-risk vascular disease (HRVD).
Morbid obesity is an increasing medical problem in the western countries. It's related to comorbidities as diabetes mellitus, hypertension, OSAS, arthrosis and hypercholesterolemia. The Roux-en-Y Gastric Bypass (RYGB) is an effective surgical therapy for morbidly obese patients. A part of these patients will have disappointing results, and have weight regain on the long term. Some studies show more weight reduction by increasing the biliopancreatic limb in patients with morbid obesity. The objective of this study is to investigate the effect of variations in the length of biliopancreatic limb on weight reduction in morbidly obese patients undergoing RYGB-surgery. We hypothesize that longer biliopancreatic limb results in more weight reduction. The study design is a prospective, randomized control trial. The patients will be randomized in 2 groups: a standard RYGB (short biliopancreatic limb) and long biliopancreatic limb RYGB.
