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.
Thrombotic microangiopathy (TMA) is a severe and life-threatening condition, often affecting the kidneys and brain. It can occur on the background of various clinical conditions. Dysregulation of the alternative pathway of complement may be the etiological factor and this type of TMA is classified, according to the current nomenclature, as primary atypical hemolytic uremic syndrome (HUS). Half the patients with primary atypical HUS present with rare variants in complement genes, although coexisting conditions are often needed for the TMA to become manifest. In patients with secondary atypical HUS, certain coexisting conditions appear to drive the disease and treatment should target the underlying condition to remit the TMA. Recently, the investigators demonstrated, by using a novel in-house developed functional endothelial cell-based test, that complement dysregulation and overactivation is the dominant cause of disease and its sequelae in a subset of patients with secondary atypical HUS, having impact on treatment and prognosis. The investigators did first prove this concept in patients presenting with TMA and hypertensive emergency. A prospective study is needed to further corroborate these findings along the spectrum of TMA. The investigators hypothesize that their functional endothelial cell-based test, the so-called "HMEC" test, can better categorizes the TMA into different groups with potential therapeutic and prognostic implications. Thus, paving the road to the ultimate goal of precision medicine.
The primary objective of this study is to determine the safety, and evaluate the efficacy of GS-248 versus placebo on Raynaud's Phenomenon (RP) in subjects with Systemic Sclerosis (SSc).
This study will investigate the efficacy and safety of ravulizumab compared to placebo in adult participants with thrombotic microangiopathy (TMA) associated with a trigger. Participants will be randomized to receive either ravulizumab plus best supportive care or placebo plus best supportive care. The treatment period is 26 weeks followed by a 26-week off-treatment follow-up period.
The HIP ATTACK-2 trial is a multicentre, international, parallel group randomized controlled trial to determine whether accelerated surgery for hip fracture in patients with acute myocardial injury is superior to standard care in reducing death at 90 days after randomization. The trial will also assess secondary outcomes at 90 days after randomization: inability to independently walk 3 metres, time to first mobilization (first standing and first full weight bear), composite and individual assessment of major complications (e.g., mortality, non-fatal myocardial infarction, acute congestive heart failure, and stroke), delirium, length of stay, pain, and quality of life.
In the last few years, high-definition (HD) videobronchoscopy has become widely available in the market and will progressively become the standard of care for airway inspection and sampling, as it provides substantially higher resolution images as compared to conventional white light bronchoscopy. Furthermore, in combination with improved video processor units, some HD videobronchoscopes offer post-processing real-time image enhancement (i-scan technology). Preliminary studies, performed in the setting of lung cancer, suggest that HD bronchoscopy with optical image enhancement (OE) may result in better detection of subtle vascular abnormalities in the airways, which are often associated with preneoplastic lesions. We hypothesize that HD videobronchoscopy could help identify bronchial involvement from sarcoidosis before it is (plainly) visible by conventional bronchoscopy.
During the Corona Virus Pandemic health care resources have become scare, and the pandemic has brought forth the need for risk stratification of patients suffering from COVID19 in order to allocate resources appropriately. One of scarcest resources is Intensive Care treatment, mostly related to the need for invasive ventilation or for (post) cardiac arrest care. To identify patients for whom ICU-treatment is most successful and those for whom it would be futile, would allow for installing appropriate advanced care directives for escalation or limitation of treatment.
A single centre prospective trial in which patients with a prior PCI for stable CAD who are referred for invasive angiography will undergo state-of-the art CCTA and dynamic CT perfusion. Subsequently invasive FFR and iFR measurements will be routinely performed in each coronary vessel.
This study evaluates the diagnostic performance and safety of [18F]PSMA-1007 PET/CT imaging in patients with suspected recurrence of prostate cancer after previous definitive treatment.
Rationale: COVID-19 is associated with severely increased morbidity and mortality in patients with severely impaired kidney function, on dialysis or alive with a kidney transplant. Therefore, effective SARS-CoV-2 vaccination would be of great clinical importance in these patients. However, SARS-CoV-2 vaccination studies have excluded patients with chronic kidney disease (CKD) so-far. Objective: To assess the efficacy and safety of SARS-CoV-2 vaccination in patients with CKD stages 4/5, on dialysis or alive with a kidney transplant as compared to controls. Study design: prospective, controlled multicenter study Study population: 175 patients with CKD stages 4/5 (eGFR < 30 ml/min/1.73m2), 175 on dialysis , 300 alive with a kidney transplant and 200 controls (partners or sibblings of patients) Intervention: SARS-CoV-2 vaccination according to standard of care. Blood will be drawn at 4 different time points (baseline and at day 28, month 6 and in a subset 28 days after a third vaccination). Main study parameters/endpoints: The primary endpoint is the antibody based immune response on day 28 after the second vaccination. Participants will be classified as responders or non-responders based on a spike (S)1 specific antibody levels of >=10 or <10 BAU/mL. The percentage of responders of each patient cohort will be compared with the percentage responders in the control group. Safety is a secondary endpoint which will be reported in terms of percentage of solicited local and systemic adverse events (AEs)graded according to severity. Other secondary endpoints include longevity of the immune response at 6 months, antibody respons 28 days after a third vaccination and levels of SARS-CoV-2 specific T and B cell responses.
