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.
Sickle Cell disease is caused by an inherited hemoglobin disorder. Healthy red blood cells are discoid and can deform and move through small blood vessels to carry oxygen to all parts of the body. In Sickle Cell disease, as red blood cells circulate and oxygen is released, the deoxygenated abnormal Hemoglobin S can begin to polymerize and cause red cells to become sticky and elongated. These "sickled" red cells are less flexible and will obstruct small blood vessels and prevent normal red cells from circulating freely, which limits oxygen delivery to tissues and organs. This is known as a "sickling crisis" or "vaso-occlusive crisis" and is the leading cause of hospitalization in patients with Sickle Cell disease. Patients suffering from a sickle crisis experience severe pain and are at risk of stroke, heart attack or even death. Current therapy is limited to hydration and symptomatic pain relief. The administration of MP4CO as an adjunct treatment to standard therapy may alleviate pain associated with a sickling crisis and potentially reduce the severity and duration of a crisis. This may shorten the time in hospital and potentially improve the quality of life for patients with sickle cell anemia.
Stimulants alleviate information processing and task performance deficits in Attention Deficit/Hyperactivity Disorder (ADHD). Long acting formulations of amphetamines such as lisdexamphetamine dimesylate (LDX) are especially valuable as they target the school day and improve classroom performance. Although stimulants have been widely used in treatment of ADHD, the exact mechanism action and effect on task performance is not completely known. According to the State Regulation Deficit (SRD) model, children with ADHD have difficulty regulating their levels of arousal/activation during tasks in response to the changing demands of the environment. This leads to problems with downregulating overaroused states and upregulating underaroused states. According to this view, stimulants exert their therapeutic effect (in part) by optimising arousal/activation levels - especially during states of underarousal/activation. Arousal/activation levels can also be altered by extrinsic factors such as event rate (ER), e.g., the rate at which information is presented. Multiple studies suggest that very fast and very slow events can both cause problems for individuals with ADHD, related to overarousal and underarousal state respectively. Putting these intrinsic (stimulants) and extrinsic (ERs) factors together leads to the prediction that changing the rate at which information is presented in a task may alter the efficacy of stimulants and affect the optimal stimulant dose level. More specifically, one dose of stimulant that may be optimal on slow ER tasks (as it increases arousal/activation level) may be less effective under high ER tasks because in such a setting arousal/activation level needs to be lowered and not increased further. Adding stimulants to an already overactivated state may exacerbate the associated problems. The implication of this is that a different dose of stimulant will be needed under different environmental conditions for optimal performance. For example, children with ADHD might require different dosage in the classroom setting to optimize performance. In addition, the neuropsychological basis of performance deficits and improvement by ER and stimulants are also unclear. According to the SRD model, the underlying mechanism can be specific problems in motor activation/preparation or effort regulation. Event-related potentials (ERP), pupil size measurements and cardiac measures enable us to see objectively how motor activation/preparation and effort are affected by ER and simulants. In this study the investigators aim to test these predictions of the SRD model and identify the neurobiological basis of stimulant action.
A phase II trial evaluating Cabazitaxel in patients with brain metastasis secondary to breast and non-small-cell lung cancer (NSCLC). OBJECTIVES: Primary: The purpose of this study is to determine if cabazitaxel can induce a reduction in the size brain metastasis in metastatic HER2-negative breast cancer and NSCLC with brain metastasis who were not previously treated with whole brain irradiation or require immediate brain irradiation. Secondary: - To determine the effect of cabazitaxel on the time to initiating whole brain irradiation or radiosurgery - To determine the effect of cabazitaxel on the time to developing neurological symptoms - To determine the effect of cabazitaxel on the time to disease progression in the brain - To determine the effect of cabazitaxel on the time to disease progression outside the brain. This will be evaluated separately for the breast and NSCLC cohorts To determine the objective extra-cranial response (if applicable). This will be evaluated separately in the breast and NSCLC cohorts - To determine the safety of cabazitaxel
This study will assess the safety and efficacy of ixekizumab (LY2439821) compared to placebo in participants with active AS.
Chronic kidney disease is associated with the accumulation of various metabolites, i.e., uremic retention solutes. Evidence is mounting that the colonic microbiome contributes substantially to these uremic retention solutes. Indoxyl sulfate and p-cresyl sulfate are among the most extensively studied gut microbial metabolites, and are associated with cardiovascular disease, chronic kidney disease progression and overall mortality. Colonic transit time is an important determinant of intestinal generation and uptake of bacterial metabolites. However, it is unknown if accelerating the colonic transit time reduces the intestinal generation and uptake of indoxyl sulfate and p-cresyl sulfate. Prucalopride is a selective, high-affinity 5-HT4 receptor agonist with a stimulating effect on colonic motility and transit. It is currently used in treating chronic slow-transit constipation. An observational study will be initiated in non-chronic kidney disease patients with chronic slow-transit constipation necessitating treatment with prucalopride to observe its effect on serum concentrations and intestinal generation of indoxyl sulfate and p-cresyl sulfate.
Patients needing lipid lowering therapy will be recruited before initiation of the treatment. For each patient, total and LDL cholesterol levels before start of therapy will be measured. One, three and six months after his/her first visit, when steady-state will be reached, for each included patient, the cholesterol levels will be re-assessed in order to evaluate the response to statin therapy calculated as the amplitude of cholesterol reduction. The aim is to assess the association between patient's genotype and the response to statin therapy.
The purpose of this study is to assess the benefit of 177Lu-DOTATATE versus interferon α-2b in patients with progressive, unresectable, non-pancreatic gastrointestinal neuroendocrine tumors resistant to therapy with somatostatin analogues, in terms of disease control.
Study is to show that QVA149 is superior to the standard of care, fluticasone/salmeterol, in patients with moderate to severe airflow limitation.
Conventional urethrography is the standard diagnostic evaluation for patients with a suspicion of urethral stricture. The radiation dose of this examination is 5-9 mSV. Sono-urethrography was introduced in 1988 (McAninch et al. , J Urol 1988); the diagnostic accuracy of sono-urethrography is equal compared to conventional urethrography, with even a better measurement of stricture length and degree of spongiofibrosis with sono-urethrography. However, sono-urethrography remained underused among urologists and radiologists. Patients will be randomly assigned into two groups: Group A: conventional urethrography Group B: sono-urethrography In case sono-urethrography is inconclusive or of poor quality, a conventional urethrography will be performed. The radiation dose in the two groups will be measured. The stricture length and location will be recorded and compared with the perioperative findings in order to evaluate the diagnostic accuracy. The complications of the procedure(s) will be recorded with a questionnaire directly after and two weeks after the conventional or sono-urethrography.
In patients with advanced multiple sclerosis, permanent urinary catheters are often used to manage the urinary incontinence and bladder emptying problems. These catheters will lead to urinary tract infection, blocking of the catheter etc.. Especially infections with certain bacteria such as proteus, enterobacteriaceae and ESBL producing enterobacteriaceae and pseudomonas can pose a problem for the hospital infection control and for the patient. This study wants to evaluate the potential role of regular bladder lavage with saline, a solution of betadine, an acid solution of acetic acid and of URotainer Twin Suby G ( Braun)in the decontamination of these bladders and the prevention of clinically relevant urinary tract infections.
