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.
Total endovascular repair of the aortic arch represents a promising option for patients ineligible to open surgery. Custom-made design of stent-grafts (SG), such as the Terumo Aortic® RelayBranch device (DB), requires complex preoperative measures. Accurate SG deployment is required to avoid intraoperative or postoperative complications, which is extremely challenging in the aortic arch. In that context, the investigators aim is to develop a computational tool able to predict SG deployment in such highly complex situations. Four patient-specific cases will be performed with complete deployment of the DB and its bridging stents in aneurysmal aortic arch. Deviations of simulation predictions from actual stent positions will be estimated based on post-operative scan and a sensitivity analysis will be performed to assess the effects of material parameters. If good agreement between simulation and reality is obtained, numerical simulations will show their ability to successfully predict the DB deployment in complex anatomy. The results will emphasize the potential of computational simulations to assist practitioners in planning and performing complex and secure interventions.
The purpose of the study is to evaluate the efficacy and safety of bimekizumab in study participants with moderate to severe hidradenitis suppurativa (HS)
Background: There is wide variety in lung disease phenotype for the delta F508 (homozygous) genotype. A leukocyte driven inflammation is most important for the pathogenesis of pulmonary disease in CF. Blood cytokines correlate negatively with pulmonary function in delta F508 homozygous patients. Gap junction proteins might be of importance for the influx of blood cells into the lung and may influence the course of pulmonary inflammation. A primary analysis (Horn et al. 2020) has shown that GJA4 variants (rs41266431) are linked to more severe disease in CF. This is very similar to variants of MBL. Aims: To assess the relationship between gap junction proteins alpha 1 (GJA1/Connexin 43) and alpha 4 (GJA4/connexin 37) genotypes and clinical disease phenotype. Moreover are GJA4 variants in terms of clinical phenotype independent of MBL variants. Methods:Patients homozygous for delta F508 get recruited from the CF centres of Bonn, Frankfurt and Amsterdam. Sequence analysis is performed for connexin 43 and 37 and MBL genotypes. Clinical disease is assessed longitudinally over 3 years by pulmonary function tests (FEV1 (forced expiratory volume in one second), FVC (=(forced vital capacity), FEF75 % (Forced expiratory flow at 75% of the pulmonary volume) pred), BMI (percentiles), P. aeruginosa colonization, diabetes mellitus and survival to end-stage CF lung disease (death or lung transplantation).
The purpose of this observational, multi-center prospective, post-market registry is to confirm real-world device safety and performance, to ensure the continued acceptability of identified risks, and detect emerging risks.
This study is designed to assess the antitumor efficacy and safety of pembrolizumab in combination with chemoradiotherapy (CRT) versus CRT alone in participants with muscle-invasive bladder cancer (MIBC). The primary hypothesis is that pembrolizumab + chemoradiotherapy is superior to placebo + chemoradiotherapy with respect to bladder intact event-free survival.
The primary objective is to evaluate the safety and tolerability of aducanumab over 100 weeks of treatment after a wash-out period imposed by discontinuation of feeder studies in participants who had previously received aducanumab (i.e. previously treated participants) or who had previously received placebo (i.e. treatment-naïve participants).
This is a randomized, double-blind, placebo-controlled, 2-way cross-over study in healthy male and female elderly participants.
18F-PSMA-1007 is a new radiopharmaceutical for the detection of prostate cancer with potential benefits over the registered 18F-Fluciclovine (Axumin). The main potential benefit is the higher detection rate of PSMA compared to Fluciclovin in the low PSA range. It may therefore be more sensitive in detecting local disease in case of biochemical recurrens. The investigators aim to compare the detection efficacy of 18F-PSMA-1007 to 18F-Fluciclovin in prostate cancer patients with biochemical recurrence (PSA levels 0.2-5 ng/ml).
Type 2 diabetes mellitus (T2DM) is a progressive disease and early intervention and prevention strategies are therefore very important. An important early hallmark in the development of T2DM is insulin resistance. Since the majority of postprandial glucose disposal occurs in skeletal muscle, improving muscle insulin sensitivity will thus have a major impact on disease prevention. Abdominally obese men and women have an increased risk to develop T2DM, and are also characterized by an impaired vascular function. This may hamper proper delivery of insulin, glucose and oxygen to muscles, thereby contributing to - and possibly causing - muscle insulin resistance. Earlier it has been shown that supplementation with L- arginine improves vascular function by improving nitric oxide (NO) bioavailability. These NO- mediated beneficial effects on vascular function may improve delivery of insulin, glucose and oxygen to the muscle tissue, thereby improving muscle insulin sensitivity and mitochondrial function. However, the doses needed of this amino acid cannot be provided by regular diets or supplements, also due to the bitter taste of L-arginine. Alternatively, smaller amounts of L- arginine with a specific combination of other nutritional components (i.e. nitrate and nitrite), which are already part of the regular diet and support alternative pathways to improve NO- mediated vascular function, may also induce beneficial effects. The investigators now hypothesize that in abdominally obese adults with impaired fasting glucose concentrations L-arginine combined with nitrate/nitrite increases muscle insulin sensitivity.
Worldwide, diabetic kidney disease (DKD) is the most common cause of chronic and end stage kidney disease. In parallel with the ever-increasing rates of obesity and type 2 diabetes (T2D), the incidence of DKD is expected to further increase in the coming years. DKD is a multi-factorial condition, involving pathophysiological factors such as chronic hyperglycemia, obesity, systemic- and glomerular hypertension, dyslipidemia, oxidative stress and pro-inflammatory cytokines. Large-sized prospective randomized clinical trials indicate that intensified glucose and blood pressure control, the latter especially by using agents that interfere with the renin-angiotensin-aldosterone system (RAS), halts the onset and (particularly) the progression of DKD, in both type 1 diabetes mellitus (T1DM) and T2DM patients. However, despite the wide use of angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs), a considerable amount of patients develop DKD, indicating an unmet need for renoprotective therapies. Sodium-glucose linked transporters (SGLT-2) inhibitors are a relatively novel glucose-lowering drug for the treatment of T2DM. These agents seem to exert pleiotropic actions 'beyond glucose control'. SGLT-2 inhibitors decrease proximal sodium reabsorption and decrease glomerular pressure and albuminuria in type 2 diabetes. In addition, SGLT-2 inhibitors reduce blood pressure and body weight. At this point in time, the renoprotective mechanisms involved with SGLT-2 inhibition still remain speculative, though a consistent finding is that SGLT-2 inhibitors reduce estimated eGFR after first dosing, which is reversible after treatment cessation. This "dip" indicates a renal hemodynamic phenomenon reminiscent of the RAS blockers and is thought to reflect a reduction in intraglomerular pressure. The potential renoprotective effects and mechanisms of combination therapy of SGLT-2 inhibitors and RAS inhibitors have not been sufficiently detailed in human type 2 diabetes. Therefore, the current study aims to explore the underlying mechanism of the improved renal hemodynamics and mechanistics of mono- and combination therapy with an SGLT-2 inhibitor and a RAS inhibitor on renal physiology in metformin and/or SU-treated T2DM patients.
