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.
The purpose of this study is to evaluate the efficacy, safety and tolerability of perampanel when given as an adjunctive therapy in subjects with refractory partial seizures.
Rationale: Investigation of the circadian rhythm of erythropoietin and melatonin in patients with various degrees of renal insufficiency Objectives: Primary objective: Is there a circadian rhythm of epo and melatonin in patients with various degrees of renal insufficiency? Primary Objective: Is there a circadian rhythm of epo and melatonin in patients with various degrees of renal insufficiency compared to patients with a normal renal function? Secondary Objective: Is there a circadian rhythm of cortisol and IGF in patients with various degrees of renal insufficiency? Secondary Objective: Is there a circadian rhythm of cortisol and IGF in patients with various degrees of renal insufficiency compared to patients with a normal renal function? Study design: Comparative study in 4 groups with various degrees of renal insufficiency, duration for each patient 24 hrs. Total duration of study 12 months, patients admitted to the hospital (on nursing ward) Study population: Patients with various degrees of renal insufficiency Main study parameters/endpoints: Analysis of the existence of a circadian rhythm in patients with a normal renal function and in patients with variable degrees of renal insufficiency Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Better knowledge of the circadian rhythm in renal insufficiency. This could lead to a more efficient administration of erythropoietin and melatonin in the future. Extent of burden is 1 venapunction for placement of infusion needle, the withdrawal of 11 times 5 ml blood in 24 hrs, continuous measurement of body temperature via capsule, 24-hour continuous ambulant blood pressure monitoring.
Background: Osteoporosis is a high-prevalence disease with a strong genetic component. Nucleotides, including ATP (adenosine 5'-triphosphate) and its purinergic receptors, play a role in bone physiology. Single nucleotide polymorphisms (SNPs) in the P2X7 receptor gene were recently found to be associated with fracture risk in a cohort of postmenopausal women. Objective: To investigate associations between purinergic receptor SNPs and osteoporosis risk in humans. Genetic data from a fracture cohort in the Netherlands with high prevalence of osteoporosis will be analyzed. Furthermore, effects of aberrant purinergic receptor signalling on bone turnover markers will be assessed ex vivo. Design: The cohort will include app. 1,000 fracture patients of 50 years and older, who will be recruited at the Maastricht University Medical Center during standard medical follow-up after a clinical fracture. The standard medical follow-up includes assessment of bone mineral density (BMD) by Dual-Energy X-ray Absorptiometry (DXA), if necessary followed by medication for osteoporosis. Prior to medication, blood samples will be collected from fracture patients to be genotyped for purinergic receptor SNPs and analyzed for biochemical markers of bone turnover. Systemic correlates of osteoporosis will be compared between osteoporotic subjects (i.e. low BMD) and non-osteoporotic controls (i.e. normal to high BMD). Subsequently, whole blood assays in patient subgroups (n=20 per subgroup), based on BMD and purinergic receptor SNPs, will be performed to evaluate ex vivo effects of ATP and related nucleotides bone markers. Study population: Patients of 50 years and older attending an outpatient osteoporosis clinic at the Maastricht University Medical Center for standard medical follow-up after a clinical, non-pathological fracture. Primary outcome parameters: BMD and purinergic receptor SNPs. Secondary outcome parameters: Bone markers.
CHR-3996 is one of a new class of anti-cancer agents - histone deacetylase inhibitors (HDACi) - that has exhibited pleiotropic activity both in vitro and in vivo against a range of human cancer cells. Regulation of the acetylation of both histone and non-histone proteins by histone deacetylase enzymes is one of the key mechanisms involved in epigenetic control of gene expression. HDACi have demonstrated activity in both in vitro cytotoxicity, and in vivo tumour xenograft studies
The purpose of this study is to explore efficacy, tolerability and safety of paliperidone Extended Release (ER) in 250 schizophrenia patients who started treatment with paliperidone ER in a naturalistic setting.
The purpose of this study is to assess the efficacy of dronedarone for the control of ventricular rate at rest and during exercise in patients with atrial fibrillation (AF) and to assess the tolerability of dronedarone in the target population.
This study was conducted to evaluate the lot-to-lot consistency of three lots of HBV-MPL vaccine and to compare their safety and immunogenicity with that of Engerix™-B.
The purpose of this study is to determine whether atazanavir use is of influence on the endothelial dysfunction associated with type 2 diabetes mellitus.
The purpose of this study is to assess the efficacy, tolerability and safety of oral administration of talampanel compared to a placebo in subjects with ALS.
Short chain fatty acids (mainly butyrate, acetate, and propionate) are produced in the large intestine by bacterial fermentation of undigested carbohydrates, such as dietary fibres. Butyrate is an important energy source of the intestinal epithelium and has a pivotal role in the regulation of epithelial cell proliferation and differentiation, immune function and mucosal protection. Non-digestible carbohydrates (prebiotics) increase the concentrations of colonic butyrate, which has been proposed to be responsible for its beneficial effects. Furthermore, butyrate enemas have been proven to be effective in the treatment of active ulcerative colitis. In the present study, the direct effects of butyrate on inflammation and parameters of colonic defence and mucosal integrity of the distal colon will be studied in 40 patients with diarrhoea predominant IBS (D-IBS) and 40 patients with ulcerative colitis in remission (UCrem) using rectal enemas. These patients groups were chosen because they have a low-grade inflammation in the large intestine, and can therefore be used as a model to study the mechanistic effects of butyrate. The design used to study the effects of butyrate in both patient groups will be a double blind randomized placebo-controlled parallel design.
