There are about 13446 clinical studies being (or have been) conducted in Belgium. 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.
The aim of this research project is to better understand the origin and clinical significance of two lupus-specific "genetic signatures" (IFN signature and plasma cell signature) in patient subgroups with well-defined clinical characteristics. Our aim is to correlate these genetic signatures with cell activation profiles and the production of specific cytokines in different populations from whole blood and in short-term cultures of these circulating cells.
The study is an extension of two parent studies (MLN0002-3024 [NCT04779307] and MLN0002-3025 [NCT04779320]). Participants must have participated in one of the previous studies. The purpose of this study is to collect the long-term safety of vedolizumab in children with UC or CD.
With the increased participation of women in sports, it is essential to develop gender-tailored training strategies for improving exercise performance. Males and females exhibit gender-specific characteristics and they therefore respond differently to physical exercise. Improving repeated sprint ability (RSA, i.e., ability to perform repeated short duration sprints separated by brief recovery intervals) in women is important for sports performance, as it is a key factor in most team and racket sports. Repeated sprint training in hypoxia is increasingly popular in this field, as it has demonstrated further improvements in sea-level repeated sprint performance than similar training in normoxia. However, these observations are based mainly on male athletes. Whether the effects of hypoxic repeated sprint training on repeated sprint performance in normoxia differ between genders is not yet known, therefore the investigators propose to examine those possible differences in this study. The aim of this study is to investigate whether the effects of hypoxic repeated sprint training on repeated sprint performance in normoxia differ between males and females who participate in team/racket sports. Considering the sex-specific characteristics that males and females exhibit, the investigators hypothesize that after 7 weeks of hypoxic repeated sprint training the improvements in repeated sprint ability at sea level will be greater in males than in females. To answer this question, the investigators will measure the following: body composition (lean body mass); body weight and height; VO2max; blood (estrogen, lactate, hemoglobin, hematocrit); repeated sprint ability (RSA) test; muscle oxygenation (concentrations for oxyhemoglobin, deoxyhemoglobin, and total hemoglobin/myoglobin); 30-s Wingate test; heart rate (HR); power output; rate of perceived exertion (RPE); visual analogue scale (VAS; pain level in legs). The investigators will recruit 48 volunteers and they will randomly assign them into the normoxic or hypoxic training group, without giving any information about their group. The volunteers should meet the following inclusion criteria: females (on monophasic oral contraceptive pill) and males, age between 18-40 years, recreationally participating in team/racket sports min 3h/week with at least 2 years of experience prior to the study. Exclusion criteria will be: smoking, exposure to altitude >1500 m one month before the study, any health conditions or injuries that could compromise the participant's safety during training/testing, prescribed medication, performing repeated sprint training more than once per week. Males and females, matched for VO2max and sprint performance, will perform repeated sprint training (3 sets during week 1-6, 2 sets during week 7 with 5min active recovery in between, 5 x 10s maximal sprints with 20s active recovery in between) in hypoxia or normoxia 2x/week for 7 weeks. Before and after the training period, the following tests and measurements will be performed: body composition analysis, VO2max test, blood sampling for measuring hemoglobin and estrogen concentrations and hematocrit, determination of hemoglobin mass, RSA test, muscle oxygenation assessment during RSA test, 30-s Wingate test and blood lactate measurements.
The optimal timing of surgical intervention in asymptomatic patients with severe aortic regurgitation remains controversial. As per cardiac magnetic resonance assessment, early surgical treatment will be compared with conventional guideline-based strategy in asymptomatic patients with severe aortic regurgitation.
This study is a comparison between the current standard practice of performing a transvaginal oocyte retrieval (TVOR) with paracervical block (PCB) and a relatively recently developed technology of virtual reality that is added to the above mentioned standard practice of TVOR + PCB. The aim of the study is to find out whether this newer technology has an advantage for the patient, in terms of anxiety and pain reduction or satisfaction.
The purpose of this study is to provide ongoing access to study treatments for participants with multiple myeloma or smoldering multiple myeloma benefiting from treatment in certain Janssen Research and Development (R&D) studies that use daratumumab as part of the study treatment regimen: access for all participants regardless of treatment group in daratumumab studies and access to participants in daratumumab-containing arms in the non-daratumumab studies will be allowed from studies which have reached clinical cutoff for final analysis. Certain long-term safety data will continue to be collected from study participants.
Recently, a new device for measuring physiological lesion severity, the pressure microcatheter, was introduced. The pressure microcatheter provides similar information to the conventional measurement technique but differs as it is easily advanced on a customary coronary wire and simplifies pullback maneuvers. The pressure microcatheter has been shown to provide comparable FFR results to pressure wires. Insightful-FFR is an investigator-driven, multicenter, randomized, open-label and prospective trial of patients with stable coronary artery disease or stabilised non-ST elevation acute coronary syndrome (ACS) with epicardial stenosis considered for PCI aiming at comparing clinical outcomes between pressure microcatheter and pressure wire-guided strategies. The study hypothesis states that the use of a Pressure Microcatheter for clinical decision making would be non-inferior to pressure wire-based strategy After determining the presence of a coronary artery disease/ stabilized acute coronary syndrome, patients will be randomized to use a pressure microcatheter (investigational device) or a pressure wire (comparator) to guide and optimize percutaneous coronary intervention (PCI). Patients will be followed up in hospital at 12 months and yearly until five years.
This is a phase 3, multicenter, randomized, placebo-controlled, double-blind study of treatment with brepocitinib (TYK2/JAK1 inhibitor) in adults with dermatomyositis (DM). The primary objective of this study is to assess the efficacy of two dose levels of brepocitinib in comparison to placebo, as measured by differences in the Total Improvement Score (TIS). After 52 weeks of double-blind treatment, participants have the option to continue therapy in a 52 week open-label extension phase where all participants will receive brepocitinib.
This study is designed as a randomised multicentric parallel group pragmatic trial of Descemet Stripping Automated Endothelial Keratoplasty (DSAEK) versus Descemet Membrane Endothelial Keratoplasty (DMEK) in corneal endothelial decompensation. the purpose is to compare the clinical and patient reported outcomes of both therapies across a broad range of indications.
