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.
Rationale: Currently there are no approved treatments for COVID-19. In the Dutch treatment protocol guideline (SWAB) designated treatment is supportive care with the option to add chloroquine base (CQ) or hydroxychloroquine (HCQ). CQ and HCQ are implemented because of their in vitro activity, results from small animal studies, and anecdotal patient's data. There are no published randomized studies with these medications in patients with disease caused by any coronavirus. Objective: To evaluate if treatment with only supportive care or addition of one of two anti-COVID_19 agents (chloroquine or hydroxychloroquine) results in less disease progression in patients with moderate to severe COVID-19 who require hospital admission. Study design: Multicentre, cluster randomized cross-over, open label trial. Hospitals will be randomly allocated to one of 3 treatment arms in sequential periods of one week: chloroquine base versus hydroxychloroquine versus supportive care without any drug presumed active against SARS-COV-2. Patients will be treated based on the date of inclusion. Study population: Adults aged of 18 years and older with moderate to severe, with a NEWS-2 score ≤ 5, laboratory confirmed COVID-19, who require hospital admission in a ward outside the Medium Care or Intensive Care. Intervention (if applicable): Depending on the treatment arm, the study subject will receive only supportive care or an addition with one of the two agents active against SARS-CoV-2 (chloroquine or hydroxychloroquine). Main study parameters/endpoints: Disease progression defined as a NEWS-2 score ≥ 7 within 14 days, or admission to Medium Care or Intensive Care Unit, or death.
The main objectives of this study are to evaluate the long-term safety of spesolimab in patients with perianal fistulising Crohn's disease who have completed treatment in parent trials and to evaluate the long-term efficacy of spesolimab in patients with perianal fistulising Crohn's disease, who have completed treatment in parent trials
A phase 1, randomized, placebo-controlled, double-blind, dose escalation trial combining single-ascending dose and multiple-ascending dose phases of NI006 or placebo, followed by an open-label extension phase in subjects with Amyloid Transthyretin Cardiomyopathy (ATTR-CM).
The drug that will be investigated in the study is an antibody, GEN3009. Since this is the first study of GEN3009 in humans, the main purpose is to evaluate safety. Besides safety, the study will determine the recommended GEN3009 dose to be tested in a larger group of patients and assess preliminary clinical activity of GEN3009. GEN3009 will be studied in a broad group of cancer patients, having different kinds of lymphomas. All patients will get GEN3009 either as a single treatment (monotherapy) or in combination with another antibody-candidate for treatment of cancer in the blood. The study consists of two parts: Part 1 tests increasing doses of GEN3009 ("escalation"), followed by Part 2 which tests the recommended GEN3009 dose from Part 1 ("expansion").
In the past decade, the demand for colonoscopy procedures has increased significantly since the introduction of population-based colorectal cancer (CRC) screening in many western countries. Post-polypectomy surveillance will increase the number of colonoscopy procedures conducted each year even further. The invasive nature of colonoscopy and the associated health-care costs warrant the development of a new non-invasive test to reduce the number of unnecessary colonoscopies. These days, many countries use a non-invasive fecal test for CRC screening which is easy to perform at home, but test characteristics such as sensitivity and specificity are suboptimal. Multiple studies have already shown that volatile organic compound (VOC) analysis has a high diagnostic accuracy for CRC and Advanced Adenomas. An additional VOC analysis, for example through breath testing, in patients with a positive fecal immunochemical test (FIT) may reduce the number of unnecessary colonoscopies. The aim of this study is to validate the diagnostic accuracy of the AeonoseTM to distinguish patients with CRC from healthy controls, and to assess reproducibility of test results.
Prospective non-randomized parallel-assignment multi-center clinical investigation. The study design includes two subject cohorts: 1) Paroxysmal Atrial Fibrillation Main Study, and 2) Paroxysmal Atrial Fibrillation High Standard Power Substudy. Subjects in the main study cohorts are to be treated using the full range of ablation power settings in the Instructions For Use. Subjects in the High Standard Power Substudy are to be treated in the upper end of the recommended ablation power settings (40-50 Watts).
Subclinical hypothyroidism (SCH) is common among the elderly population and has been associated with neuromuscular impairment. Muscular symptoms such as weakness, myalgia and cramps are more often reported by SCH patients compared to euthyroid controls. Sarcopenia is the age-related loss of muscular mass and function and its assessment includes three dimensions (muscle quantity, muscle strength and physical performance). To date, evidence is lacking about the effect of thyroid hormone replacement on skeletal muscle impairment in SCH patients. The aim of the study is therefore to evaluate the impact of levothyroxine therapy on sarcopenia measures in SCH. This is a nested substudy within two large international multicenter randomized controlled trial of elderly participants with SCH (TRUST Study, clinicaltrials.gov ID NCT 01660126; and IEMO Study, Netherland Trial Register ID NTR3851). Those two trials shared a very similar study design. The cohorts will therefore be analyzed as a single study population.
This study will evaluate the efficacy and safety of elexacaftor (ELX) / tezacaftor (TEZ) / ivacaftor (IVA) triple combination (TC) in subjects 6 through 11 years of age with cystic fibrosis (CF) who are heterozygous for F508del and a minimal function (MF) mutation (F/MF genotypes).
Since December 2019 the world has been shaken with an enormous global threat: the Covid-19 pandemic. This new kind of coronavirus is generating an unprecedented impact both on the general population and on the healthcare systems in most countries. Health services are trying to expand their capacity to respond to the pandemic, taking actions such as increasing the number of beds; acquiring necessary equipment to provide intensive therapy (ventilators), and calling retired health professionals and health students so they can assist the overwhelmed health care workforce. Unfortunately, these organizational changes at health facilities, along with the fears and concerns of becoming ill with the virus or infecting their families, put an enormous emotional burden on workers in health services which may lead to negative outcomes on mental health in this population. Recent cross-sectional studies in China indicate that health service workers exposed to people with Covid-19 reported higher rates of depressive and anxious symptoms. This negative impact on mental health among health workers in China has also been informally reported in other countries where the Covid-19 pandemic has been devastating in its effects (such as Spain and Italy), as well as in countries where the pandemic is becoming a growing public health problem. This is particularly relevant in regions with fewer resources (Latin America, North Africa), where there are limited means and the response from the health system is usually insufficient. Moreover, it is necessary to study these negative effects longitudinally considering that some effects will appear over time (post-traumatic stress). The COVID-19 HEalth caRe wOrkErS (HEROES) study is a large, bottom-up, South-North initiative aimed to evaluate the impact of the COVID-19 pandemic on the mental health of health care workers (HCWs). HEROES encompasses a wide variety of academic institutions in 19 LMICs and 8 HICs, in partnership with the Pan American Health Organization (PAHO) and with support from the World Health Organization (WHO). The HEROES study is led by Dr. Rubén Alvarado at University of Chile, and Dr. Ezra Susser and Franco Mascayano at Columbia U Mailman School of Public Health.
Radiation therapy is predominantly based on a Computed Tomography (CT) scan obtained during the treatment planning phase. During the course of radiotherapy, however, both the tumor and organs at risk (OAR) are variable in position, shape and size between fractions, and during beam delivery within one treatment fraction. Around the clinical target volume (CTV) a safety margin (Planning Target Volume, PTV) is created to account for these geometric uncertainties to ensure that the tumor receives the prescribed dose. Direct integration of imaging at the linear accelerator enables daily monitoring of patient positioning, tumor position, and alterations in patient anatomy. Image guided radiotherapy (IGRT) enables the detection and immediate correction of such deviations and increases the precision of delivery. Adaptive radiotherapy has become an important strategy for serially modifying dose distributions in a manner that can substantially reduce OAR dose and subsequent toxicity, while maintaining adequate target coverage. Current adaptive protocols rely upon a standard CT-based workflow and (cone-beam) CT-based image guidance. Magnetic Resonance Imaging (MRI) has superior soft-tissue contrast over CT and seems a very promising modality to integrate in the radiation treatment process, facilitating better visualization of the tumor and OAR during treatment.
