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.
Identifying the outline of a Gross Tumour Volume (GTV) in lung cancer is an essential step in radiation treatment. Clinical research, such as radiomics and image-based prognostication, requires the GTV to be pre-defined on massive imaging datasets. The ARGOS community creates an open-source and vendor-agnostic federated learning infrastructure that makes it possible to train a deep learning neural network to automatically segment Lung Cancer GTV on computed tomography images. To reduce risks associated with sharing of patient data, we have used a data-secure Federated Learning paradigm known as the "Personal Health Train" that has been jointly developed by MAASTRO Clinic and the Dutch Comprehensive Cancer Organization (IKNL). The successful completion of this project will deliver a highly scalable and readily-reusable framework where multiple clinics anywhere in the world - large or small - can equitably collaborate and solve complex clinical problems with the help of artificial intelligence and massive amounts of data, while reducing the barriers associated with moving sensitive patient data across borders.
This is a Phase III open-label study to assess if camizestrant improves outcomes compared to standard endocrine therapy in patients with ER+/HER2 - early breast cancer with intermediate or high risk for disease recurrence who completed definitive locoregional therapy (with or without chemotherapy) and standard adjuvant endocrine therapy (ET) for at least 2 years and up to 5 years. The planned duration of treatment in either arm of the study is 60 months.
The goal of this trial is to learn how well Setmelanotide works to improve weight reduction, hunger, and quality of life in patients 4 years of age and older with acquired Hypothalamic Obesity (HO). To determine how well setmelanotide works and how safe it is, patients with HO will take a daily injection of either setmelanotide or placebo and complete trial assessments for up to 60 weeks.
Heparin reversal by protamine administration after transcatheter aortic valve implantation (TAVI) may reduce bleeding events. However, protamine can also cause life-threatening allergic reactions. High-quality evidence regarding the clinical safety and efficacy of routine protamine administration after TAVI is lacking. The aim of this clinical trial is to determine if routine protamine administration, compared with selective protamine administration, reduces the risk of cardiovascular mortality or bleeding within 30 days after transcatheter aortic valve implantation.
Patients with Chronic Coronary Syndrome (CCS) undergoing with elective percutaneous coronary intervention (PCI) are treated with dual antiplatelet therapy (DAPT), consisting of aspirin combined with clopidogrel for 6 months. The aim of DAPT is to prevent recurrent thrombotic events, i.e. death, stent thrombosis and/ or myocardial infarction (MI). However, the trade-off of thrombotic prevention by DAPT is an increased risk of bleeding. Multiple strategies to reduce bleeding risk and optimize outcomes have been proposed. On one hand the bleeding risk can be reduced by shortening the duration of DAPT and omitting aspirin. This has been proven effective in patients with acute coronary syndromes (ACS) compared to standard DAPT, without a significant difference in thrombotic events. On the other hand, personalized medicine by means of genotyping to ensure that a patient is treated with an, for them, effective drug, can be a strategy to optimize patients outcomes. In CCS patients the preferred P2Y12-inhibitor is clopidogrel. However, clopidogrel must first be activated by the CYP2C19 enzyme in the liver. Only then can clopidogrel inhibit the P2Y12-receptor and prevent platelet activation. Almost thirty percent of patients has a genetic variation of the gene encoding this CYP2C19 enzyme. In these patients, clopidogrel is not or hardly activated, putting them at a higher risk of thrombotic events than patients who do not have this gene variation. By determining the CYP2C19 genotype, it is possible to estimate whether clopidogrel will be effective or not. In this trial the investigators evaluate the pharmacodynamic effects of genotype guided P2Y12-inhibitor monotherapy in patients with CCS undergoing PCI. In the intervention arm the CYP2C19 genotype will be assessed using a point-of-care test device on the cardiology ward, which can be performed by (research) nurses. Patients with a CYP2C19 loss-of-function (LOF) allel will be treated with monotherapy ticagrelor or prasugrel. Patients who are non-carrier of a LOF allel will receive clopidogrel. The control arm will be treated with the current standard-of-care, which is DAPT, consisting of aspirin combined with clopidogrel for 6 months. The main goals is to assess the antithrombotic effects of individualized P2Y12 monotherapy strategy versus clopidogrel plus aspirin in elective PCI patients.
This goal of this single arm, single center, exploratory phase I/II clinical trial is to learn more about the immunological efficacy, safety and feasibility of an autologous tumor lysate-loaded autologous XP-DC (cDC1)-based vaccine in patients with ovarian cancer.
In elderly atrial fibrillation (AF) patients, AF is usually a manifestation of risk factors and comorbidities not only limited to cardiovascular diseases. Especially in elderly often more than two comorbidities are present. The presence of comorbidities also affects outcomes in AF patients. Current healthcare systems are single-disease focused, which increases the risk of underdiagnosing, replicating diagnostic tests and adverse drug-drug interactions, placing a high burden on healthcare costs. Healthcare systems and hospitals are in need of new care pathways to address the complexity of multimorbid AF patients and to reduce costs. The EHRA-PATHS consortium set out to address this need for change in management for multimorbid, elderly AF patients in Europe through the development of new care pathways. The aim of this study is to evaluate the current management of risk factors and comorbidities, and subsequently implement the newly developed care pathways and evaluate if these pathways lead to better management of risk factors and comorbidities in multimorbid, elderly AF patients, compared to current standard care.
The goal of this feasibility study is to get insight into the receptivity of a JITAI aimed at healthy dietary intake in inhabitants of a small city in the Netherlands. The main question it aims to answer is: • what is the right time and the right location to send notifications to people and for what type of interventions are people most receptive? Furthermore, the aim is to get insight into the relevance and usability of the app, the privacy concerns that people have and the perceived effectiveness of the app on dietary intake. Participants will test our app for 2 weeks, of which they will receive prompts during one week.
The goal of this prospective phase II feasibility study is to evaluate two additional local treatment options in rectal cancer patients with a good clinical response after neoadjuvant (chemo)radiation: contact x-ray brachytherapy versus extension of the waiting interval with or without local excision, and to investigate which rate of organ preservation can be achieved.
Surgery remains an important treatment modality in the treatment of hepatopancreatobiliary (HPB) malignancies, but the physiological stress caused by surgery is at the same time a challenge for the homeostasis of patients. A patient's preoperative aerobic capacity has been found to have a consistent relation with postoperative outcomes in major abdominal surgery, with low aerobic capacity being associated with a higher risk of postoperative morbidity and mortality. Preoperative exercise prehabilitation programs can effectively increase the ability of patients to cope with surgical-induced allostatic load, by improving aerobic capacity, and functioning of the respiratory, cardiovascular, and/or musculoskeletal systems. However, besides the effect of exercise prehabilitation on physical fitness in terms of improvement of aerobic capacity as measured by the cardiopulmonary exercise test (CPET), the exact role of adaptations in cardiac and/or skeletal muscle function contributing to the improvement in aerobic capacity is still unknown. Insight in the physiological adaptations that lead to improvement in aerobic capacity after prehabilitation in patients with low aerobic capacity will enable caregivers to individually optimize the exercise program (e.g. by changing exercise frequency, intensity, duration and type) and better explain the rationale and effectiveness behind the short-term physical exercise training program to patients. Therefore, the main objective of this study is to assess the central (cardiac function) and peripheral (skeletal muscle function) physiological adaptations in response to short-term exercise prehabilitation. Secondary objective is to assess the relationship between immune function and exercise. In this study, unfit patients are asked to undergo additional in-magnet exercise testing to investigate the central and peripheral physiological adaptations in response to exercise prehabilitation.
