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.
Primary, this study aims to develop and validate a computer-aided diagnosis (CADx) system for the characterization of colorectal polyps. Second, this study evaluates the effect of using a clinical classification model Blue Light Imaging Adenoma Serrated International (BASIC) on the diagnostic accuracy of the optical diagnosis of colorectal polyps compared to intuitive optical diagnosis for both expert endoscopists and novices.
The SUPERSURG RCT trial investigates the efficacy and safety of the endovascular treatment of stenosis or restenosis in the common femoral artery (CFA) of patients presenting with Rutherford classification 2,3 or 4 with a Supera Vascular Mimetic Implant of Abbott, compared to classic surgical common femoral artery endarterectomy. The Supera Vascular Mimetic Implant has an interwoven design and has a high crush resistance and is, when correctly implanted, an ideal stent to treat eccentric calcified plaques in the CFA. An expected total of 143 patients will be treated with the Vascular Mimetic Implant of Abbott and compared to a control group of another 143 patients that will be treated with classic surgical endarterectomy of the common femoral artery. Assignment to the treatment groups will be at random. Patients will be invited for a follow-up visit at 1, 6, 12, 24 and 36 months post-procedure. The primary efficacy endpoint is defined as follows: freedom from clinically-driven target lesion revascularization and binary restenosis at 12 months. The primary safety endpoint is defined as follows: a composite of overall death, cardiac, pulmonary, renal complications, sepsis, target lesion revascularisation and wound related complications through 30 days post-index procedure. The secondary endpoints are defined as technical success, primary patency in the deep femoral artery, primary patency in the target lesion, target lesion revascularisation, target vessel revascularisation, binary restenosis, duration of initial hospital stay, sustained clinical improvement, change of walking impairment questionnaire score from baseline, change in target limb Rutherford classification, change in target limb ABI/TBI from baseline, all cause death, thrombosis at the target lesion through 6, 12, 24 and 36 months post-procedure.
The purpose of this study is to evaluate bintrafusp alfa in participants with metastatic or locally advanced urothelial cancer. This trial provides the first evaluation of bintrafusp alfa in participants with urothelial cancer that has progressed following platinum therapy.
This study investigates an innovative treatment for relapsed or refractory acute myeloid leukemia exploiting administration of ex vivo-generated allogeneic natural killer (NK) cells with preceding non-myeloablative conditioning chemotherapy with or without subsequent in vivo IL-2 cytokine support.
The purpose of this national, multicenter service review is to determine and compare ventilation management in COVID-19 patients in the Netherlands, and to determine whether certain ventilation settings have an independent association with duration of ventilation. In every adult invasively ventilated COVID-19 patient from a participating ICU, granular ventilator settings and parameters will be collected from start of invasive ventilation for up to 72 hours. Follow up is until ICU and hospital discharge, and until day 90. The primary outcome includes main ventilator settings (including tidal volume, airway pressures, oxygen fraction and respiratory rate). Secondary endpoints are ventilator-free days and alive at day 28 (VFD-28); duration of mechanical ventilation; use of prone positioning and recruitment maneuvers; duration of ICU and hospital stay; incidence of kidney injury; and ICU, hospital, 28-day and 90-day mortality.
Rationale: Atrial fibrillation (AF) and heart failure (HF) can cause each other and sustain each other. Combined, the two diseases negatively influence each other's prognosis and lead to higher mortality. Studies in HF patients in which the AF burden is reduced by AF ablation show promising results toward improved prognosis, but so far only one randomized trial is conducted that focused on major clinical endpoints. As the selected patients in this trial were not representative for the entire population and its ablation method varied from patient to patient, it is the aim of the present study to confirm that early invasive therapy consisting of a strict pulmonary vein isolation (PVI) protocol using cryoballoon therapy has positive effects on hard clinical endpoints in a wider variety of patients in the HF population. Furthermore, there are no studies which compare cost-effectiveness of an early invasive strategy in this patient category. The investigators expect that avoided hospitalizations and healthcare resource utilizations lead to lower costs in the AF ablation group, despite initial higher costs of the procedure. Objective: To compare outcome and cost-effectiveness of early AF ablation by PVI using cryoballoon therapy with standard (medical) therapy in patients with heart failure with reduced ejection fraction. Study design: Multicenter, randomized, open label clinical trial. Study population: Symptomatic adult patients with heart failure with reduced ejection fraction (<40%) and paroxysmal or persistent AF. Intervention: AF ablation (PVI) using cryoballoon therapy. Outcome measures: The primary endpoint is a combined endpoint of all-cause mortality, unplanned cardiovascular hospitalization, and stroke (time-to-event analysis). Secondary endpoints of the trial are: - A combined endpoint of mortality, number of unplanned cardiovascular hospitalizations, and stroke (recurrent-event analysis); - A hierarchical endpoint of mortality, unplanned cardiovascular hospitalizations, stroke, and HF complaints; - Cost-effectiveness. Key exploratory endpoints include individual components of the combined endpoints, days alive out of the hospital, hospitalizations for heart failure, recurrence of atrial arrhythmia, and quality of life.
Rationale: Although there are several individual factors which are known to influence the chances of successful atrial fibrillation (AF) ablation, it remains a challenge to identify patients at risk for ablation failure with satisfactory certainty. Objectives: To identify predictors of success of AF ablation including clinical factors, AF recurrence patterns, anatomical and electrophysiological characteristics, circulating biomarkers and individual genetic background. Study design: Prospective registry of patients undergoing AF ablation. Clinical characteristics and results of routine tests are collected. In addition, the following (non-standard) tests are performed: extended surface electrocardiogram (extECG), extended rhythm monitoring, biomarker testing, genetic analysis, questionnaires. In subgroups of patients transesophageal electrocardiogram (TE-ECG), epicardial electroanatomical mapping and/or left atrial appendage (LAA) biopsy is performed. Study population: Patients aged 18 years and older with documented AF, scheduled for AF ablation. Main study endpoints: Ablation success after 12 and 24 months, defined as freedom from any episode of documented atrial arrhythmia after the blanking period.
Passive immunization with immunoglobulins is occasionally used as therapy for the treatment of viral infectious diseases. Immunoglobulins are used for the treatment of CMV disease, and is effective as prophylaxis when given soon after exposure to varicella zoster virus, rabies, and hepatitis B virus. Neutralizing antibodies against MERS, SARS-CoV-1 and SARS-CoV-2 have been shown to be present in patients previously infected with MERS, SARS-CoV-1 and SARS-CoV-2 respectively. During the 2003 SARS outbreak in Hong-Kong,a non-randomized study in hospitalized SARS patients showed that treatment with convalescent plasma (convP) from SARS-recovered donors significantly increased the day 22 discharge rate and decreased mortality. A study in non-human primates showed that rhesus macaques could not be re-infected with SARS-CoV-2 after primary infection. With no proven effective therapy against COVID, this study will evaluate the safety and efficacy of convalescent plasma from COVID-recovered donors as a treatment for hospitalized patients with symptomatic COVID-19. The study will focus on patients who tested positive for SARS-CoV-2 in the last 96 hours before inclusion Primary objectives • Decrease overall mortality in patients within COVID disease Study design: This trial is a randomized comparative trial. Patients will be randomized between the infusion of 300mL of convP with standard of care. Patient population: Patients with PCR confirmed COVID disease, age >18 years Donors will be included with a known history of COVID who have been asymptomatic for at least 14 days. Intervention: 300mL of convP Duration of treatment: ConvP will be given as a one-time infusion Duration of follow up: For the primary endpoint: until discharge or death before day 60, whichever comes first. For the secondary endpoints (with separate consent) up to 1 year. Target number of patients: 426 Target number of donors: 100 Expected duration of accrural: 36 months
The purpose of this study is to provide evidence that a therapy of Ulcerative Colitis (UC) disease adjusted on tight monitoring of non-invasive parameters, such as clinical symptoms and faecal calprotectin (FC) (substance that is released when intestines are inflamed and that can be measured in faeces), can provide significantly higher benefit for the participants in terms of disease control and quality of life (QoL) improvement, compared to a symptom-based approach only.
The main objective of this study is to investigate whether controlled dose reduction of IL17 or IL23 inhibiting biologics is not inferior compared to usual care in psoriasis patients. Therefore, a pragmatic, multicentre, randomized, controlled, non-inferiority study will be carried out.
