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 of SHP647 in inducing remission, based on composite score of participant-reported symptoms and centrally read endoscopy, in participants with moderate to severe ulcerative colitis (UC).
The purpose of this study is to demonstrate the impact of secukinumab on the progression of structural damage in the spine, as measured by the modified Stoke Ankylosing Spondylitis Spine Score (mSASSS) in patients with Ankylosing Spondylitis (AS).
Twenty-four healthy hookworm-naive volunteers will be exposed to 50 L3 Necator americanus larvae for a maximum of three times.
The purpose of this study is to evaluate prospectively ventilatory practices in the perioperative cardiac surgery period.
The purpose of this study is to evaluate the effect of treatment withdrawal compared to continued treatment with golimumab (GLM) administered by subcutaneous (SC) injection on the incidence of a "flare" in non-radiographic axial spondyloarthritis over up to 12 months. The primary hypothesis is that continued treatment with golimumab is superior to treatment withdrawal, based on the percentage of subjects without a "flare" during up to 12 months of blinded therapy.
The current limitations in prostate cancer diagnostics lead to over- and undertreatment for a significant fraction of patients. Confocal Laser Endomicroscopy (CLE) and Optical Coherence Tomography (OCT) are focal imaging modalities with potential for in-vivo prostate imaging. The investigators anticipate that integrating focal imaging with MRI/TRUS fusion will further improve prostate cancer detection and provides a real-time histopathological threedimensional representation of the tumor lesions. This is an investigator-initiated, prospective in-vivo safety and feasibility study with transperineal template mapping biopsies (TTMB) and two focal imaging methods, CLE and OCT, in prostate tissue.
A burgeoning body of research has pointed to increased efficacy of clozapine (CLZ) over other antipsychotics in schizophrenia (SCZ). On the other hand, safety concerns likely cause underutilization across a range of European and other nations. The lack of data available to predict efficacy and adverse drug reactions (ADRs) of CLZ further contributes to underprescription rates in these countries. Here, we hypothesize that (epi)genetic and non-genetic factors aid to help predict treatment outcome (efficacy + ADRs) to CLZ. We furthermore posit that such prediction will result in enhanced quality of life of both patients and family members. Our primary objective is to predict CLZ treatment outcome based on phenotypic and genetic data obtained through the current design. The first secondary objective is to investigate which methylation levels/patterns are correlated with CLZ treatment outcome. The second secondary objective is to aid in the further elucidation of the genetic architecture of SCZ and any possible differences between 'regular' SCZ patients and those on CLZ, who are generally more severely ill. We thus intend to cover two currently unmet needs using a precision medicine approach: the lack of knowledge about determinants of treatment response to CLZ and the lack of insight into neurobiological differences between 'regular' SCZ and relatively treatment resistant subjects (CLZ users). The prime analysis will be a common variant hypothesis-generating genotyping endeavor investigating treatment response to CLZ. Additional analyses include whole-genome methylation and gene expression analyses and analyses of non-genetic determinants of response. We will include 2,500 CLZ treated patients for our discovery cohort, which is in line with previous whole-genome pharmacogenomics studies and our power calculations. We will replicate any genome-wide loci using our prospectively collected cohort of new users (N=59). Potential yields include a publicly available prediction tool to help identify patients responsive to CLZ in early disease stages and prevent harmful effects. In addition, common variant analyses compounded by pathway analyses may help elucidate the mechanisms of action of CLZ. We ask for broad informed consent from participants ensuring rich, longitudinal phenotypic and genotypic data resources for both currently planned and future analyses, allowing e.g. next-generation sequencing focused on both CLZ and SCZ disease genetics (e.g. in large consortia). We plan to also generate polygenic risk scores (PRS) of CLZ efficacy and use those to identify other diseases or patients for which CLZ may be helpful, e.g. schizoaffective disorder patients who are sometimes first treated with mood stabilizers. Last, evidence hints that disparaging genetic loci influence efficacy to different antipsychotics. Adding genetic data from our cohort to existing datasets of response to other antipsychotics may help identify such loci. Finally, comparison studies with non-CLZ using patients suffering from SCZ may deepen the understanding of biological mechanisms underlying treatment resistance (or: a relatively severe course of illness).The results of this genetic part of the study will be combined with the results from our other research protocol 'Phenomics and genomic of clozapine pharmacotherapy - New Users'.The overarching goal of both projects is to create a prediction model for clozapine outcome (response (and side effects). This model includes genetic, epigenetic and clinical data.
The purpose of this study is to determine if an investigational drug can prevent Bronchopulmonary Dysplasia, reducing the burden of chronic lung disease in extremely premature infants, as compared to extremely premature infants receiving standard neonatal care alone.
The current high-sodium, low-potassium diet contributes to the high prevalence of high blood pressure (hypertension). Indeed, the anti-hypertensive effects of potassium supplementation are well-established. Hypertension is even more prevalent and resistant in patients with chronic kidney disease (CKD) and contributes to further decline in kidney function. Four recent epidemiological studies (published 2014 - 2016) showed that higher dietary potassium intake was associated with better renal outcomes. All studies recommended an intervention study with potassium supplementation in patients with CKD, but this has not been performed. The aim of this study is to study the renoprotective effect of potassium supplementation in patients with CKD (stage 3b or 4, i.e. estimated glomerular filtration rate [eGFR] 15 - 45 ml/min/1.73 m2).
This study is designed as a prospective observational feasibility study. The investigators will study whether vulnerable plaques on OCT (fibrous cap ≤ 70 μm) show a locally increased uptake of 18F-choline on PET-MRI compared to stable plaques and whether the culprit plaque shows a locally increased uptake of 18F-choline on PET-MRI compared to non-culprit plaques. First, 15 NSTEMI or STEMI patients who underwent urgent percutaneous coronary intervention (PCI) of the culprit vessel, who are diagnosed with multivessel coronary disease and are currently scheduled for a second PCI at the VieCuri hospital will be included. These patients will be subjected to an additional 18F-choline PET-MRI examination at the MUMC+ and an additional optical coherence tomography (OCT) examination (during the PCI procedure at the Viecuri hospital). OCT will be performed as a reference standard to validate 18F-choline PET-MRI for detection of vulnerable plaques in the coronary arteries. In addition, 15 NSTEMI patients, who are scheduled for PCI of the culprit lesion at the MUMC+, will be subjected to an additional 18F-choline PET-MRI examination at the MUMC+. Hereby, the culprit coronary vessel and thereby the culprit plaque can be identified by the location of the myocardial infarct, as identified by late enhanced MRI. The investigators will study whether the culprit plaque shows an increased 18F-choline uptake on 18F-choline PET-MRI compared to non-culprit plaques in the other coronary arteries. All patients will receive standard, guideline-based clinical care, while PET-MRI and OCT will be performed as additional measurements. Before the start of the study, 5 stable angina pectoris patients that are scheduled for a PCI procedure at the MUMC+ will be included at the MUMC+ for a single PET-MRI scan to optimize the parameters of the coronary PET-MRI scan.
