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.
Subjects enrolled in this study will have biopsies obtained and sent to Dr. Fitzgerald's lab for analysis of a validated biomarker panel. Subjects will be stratified to either high or low risk of progression to esophageal adenocarcinoma (EAC) based on biomarker panel results. Biomarker panel results will not be communicated to sites. Subjects with low grade dysplasia will be offered the option of treatment (radiofrequency ablation (RFA)) as part of routine care. Subjects with low grade dysplasia who do not want RFA and subjects with no dysplasia will receive surveillance endoscopy in 1 year per routine care. All subjects will be administered a questionnaire seeking information about hypothetical willingness to be randomized to treatment or surveillance.
The successful re-opening of a blocked coronary artery has a beneficial effect on the further clinical course (e.g. improvement of clinical symptoms, improved quality of life, increased heart function, etc.). However, some types of blockages are more difficult to open by means of percutaneous coronary intervention (PCI), a procedure which is commonly used for these kind of problems. This procedure makes use of a technique in which special wires, balloons, stents (metal or polymeric tube-like structures) and devices are utilized to re-open or revascularize a blockage in one of the blood vessels of the heart. This type of blockages are chronic total occlusions (CTO). CTOs have certain characteristics which impede the revascularization of the blood vessel. Nevertheless, remarkable progress has been achieved over the past few years in the area of CTO revascularization or CTO PCI. A large range of CTO dedicated materials, such as guidewires, guiding catheters, devices, balloons and stents, as well as different techniques have been developed. However, at present, reluctance to open CTOs still exists, due to the indications and outcomes of percutaneous revascularization as well as the technical difficulties which commonly arise during these interventional procedures. The presence of these difficulties results in suboptimal success rates worldwide (±70-80%), despite these many innovations. To increase these success rates and to make sure more interventional cardiologists will treat CTOs, a hybrid treatment algorithm has been developed with the materials (e.g. CrossBoss™ catheter; Bridgepoint Medical, Inc.) and techniques, currently already available. The main purpose of this study is to evaluate the efficacy and efficiency of this hybrid algorithm as well as validating the efficacy of one of the materials (CrossBoss™ catheter), used in this algorithm. To be able to do this, data concerning the patients' demographics, CTO characteristics, procedure and outcome will be collected in the form of a registry. This registry will be performed in several European centra (Belgium, the Netherlands, United Kingdom, France). Since the study will only collect data and no intervention is performed, this will be an observational study. At regular time points, the data will be checked for errors or inconsistencies. To do this, site visits will be performed at pre-defined times.
This study will assess efficacy of secukinumab, compared to ustekinumab, in patients that have plaque-type psoriasis
Cryoballoon based therapy is an established therapy for the treatment of (paroxysmal) atrial fibrillation. However, with the rapid evolution in cryoablation technique and its increased effectiveness, the risk of complications increases. Therefore it is of utmost importance to define the optimal duration of cryoballoon ablation time.The objective of the study is to assess the optimal ablation duration using the second generation cryoballoon for isolation of pulmonary veins in the treatment of atrial fibrillation.
Voriconazole is a broad-spectrum antifungal agent. There is evidence for a relation between the efficacy and safety of voriconazole and voriconazole trough concentrations. There are several factors that could influence voriconazole concentrations. Inflammation could be one of these factors. In a retrospective study was observed that reduced metabolism of voriconazole was related to inflammation in patients with severe infections. Reduced metabolism of voriconazole resulted in high voriconazole levels and low N-oxide metabolite (inactive metabolite of voriconazole) levels. The purpose of this study is to determine an algorithm to guide dosing of voriconazole during severe inflammation and to develop a multiple linear regression model to describe the contribution of CRP concentrations to the variability in voriconazole levels and metabolic ratio.
Pilot study enrolling up to 12 patients at a single investigational site in the Netherlands. Patients for TAVR will be enrolled to receive the Embolic Deflection Device throughout the duration of the TAVR procedure.
The primary objective is to demonstrate the non-inferiority of edoxaban (preceded by a short course of LMWH) compared with dalteparin for the prevention of the combined outcome of recurrent venous thromboembolism (VTE) or major bleeding in subjects with VTE associated with cancer during a 12-month study period. If non-inferiority is established, LMWH/edoxaban will be compared with dalteparin for superiority.
The purpose of Phase 1b of the study is to determine the maximum tolerated dose (MTD) of oprozomib in combination with melphalan and prednisone (OMP). The purpose of Phase 2 of the study is to estimate the overall response rate (ORR) and complete response rate (CRR) of the OMP combination.
Insulin resistant subjects and type 2 diabetic patients are characterized by a decreased metabolic flexibility: a reduced capability to switch from fat oxidation in the basal state to carbohydrate oxidation in the insulin-stimulated state. This metabolic inflexibility is an early hallmark in the development of diabetes. Recent evidence suggests that a low carnitine availability may limit acetylcarnitine formation, thereby reducing metabolic flexibility. We propose to test the hypothesis that metabolic inflexibility in pre-diabetic subjects and diabetic patients is due to a reduced capacity to form acetylcarnitines.
The purpose of this study is to compare edoxaban to warfarin (with enoxaparin, if needed). It will see if edoxaban prevents stroke and other blood clotting problems as well and as safely as warfarin. People with atrial fibrillation (irregular heartbeat) might be able to join. Their doctors must plan to use shock to make their hearts beat normally. About 2200 people from different countries will join. They will have an equal chance of receiving either treatment. They are anticipated to be in the study for around 82 days. Tests will include physicals and finger-pricks. Participants will provide blood and urine samples.
