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.
Fatigue is present in at least 60% of the patients with a muscle disease and can be the most disabling symptom. In combination with other impairments, this often results in low levels of physical activity and decreased social participation, leading to large societal costs. Energetic is a self-management group program aimed at improving participation and physical endurance in these patients. Our hypothesis is that Energetic results in improved participation and improved physical endurance, less experienced fatigue and better quality of life compared to usual care, without increasing health care costs.
The purpose of this study is to determine whether the use of molecular imaging using FDG-PET/CT could prevent unnecessary diagnostic thyroid surgery in case of indeterminate cytology during fine-needle aspiration biopsy.
Epilepsy occurs in 0.5-0.7% of the population, of which 25% are children. 30% Of patients with focal epilepsy do not respond well to medication and half of them are eligible for epilepsy surgery. In recent years, the importance of early epilepsy surgery has been stressed, as successful surgery may lead seizure and medication freedom and improved social and cognitive development, especially in children. The current success rate of epilepsy surgery is around 65%; During surgery intracranial electrocorticography (acute ECoG, aECoG) is recorded in some medical centers. The presence of epileptiform brian activity, spikes, identified by clinical neurophysiologists, is used to guide the neurosurgeon in the extent of the brain tissue that needs to be resected. Spikes are considered markers of the presence of epilepsy. High Frequency Oscillations (HFOs, >80-500Hz) in the ECoG have recently been identified as a new biomarker for epileptogenic tissue. Retrospective research shows that their local presence strongly relates to the seizure onset, and removal of tissue with HFOs could predict a better surgical outcome. The area showing HFOs usually overlaps with, but is smaller than the area with spikes, and HFOs do not tend to propagate to distant sites as spikes do. The identification of HFOs is more objective than of spikes and automatic detection software exists. A pilot study is performed to test the hypothesis : The intra-operative use of HFOs to delineate the epileptogenic cortex does not yield significantly worse outcome in seizure freedom than the current method based on spikes. Study design is a single blinded multi-center randomized controlled trial. In two Dutch centers, the VU medical center ( Amsterdam) and University Medical Center Utrecht. The study population (sample size 78) consists of patients of all ages with refractory epilepsy undergoing epilepsy surgery with aECoG to guide the extent of the resection. Eligible patients are randomised, after informed consent, into group 1 (HFOs) in whom a resection guided by HFOs in the aECoG (new), or into group 2 (spikes) in whom a resection is guided by epileptiform spikes in the aECoG (current standard). Ictiform spike patterns will always be resected. Main study endpoint is outcome after epilepsy surgery after 1 year of follow-up dichotomized in total seizure freedom (Engel Ia&b) vs. seizure recurrence (Engel Ic-IV).
This study evaluated change over time in neurocognitive testing in patients receiving statin therapy in combination with evolocumab (AMG 145), compared with patients receiving statin therapy in combination with placebo.
The primary aim of this study is to demonstrate bioequivalence in the rate and extent of absorption between 1600 μg selexipag test drug (administered orally as film-coated tablets of 1600 μg, twice a day (b.i.d.) and 1600 μg selexipag reference drug (administered orally as 8 film-coated tablets of 200 μg b.i.d.) at steady-state in healthy male subjects following a multiple-dose up-titration scheme.
Gastric bypass surgery is the gold standard in bariatric surgery and is a successful method to reduce weight in morbidly obese subjects. Patients qualified for gastric bypass surgery are routinely pre-treated with a low calorie diet in order to reduce liver volume and to facilitate the approach of the gastro-oesophageal junction. Pre-treatment with omega-3 fatty acids has similar effects on liver volume, but a prospective comparison of both treatments has not been performed yet. Morbidly obese patients respond differently to surgical stress, due to a number of factors. First, obesity is associated with a low-grade inflammatory state induced by an increased amount of macrophages in adipose tissue. This state is associated with higher levels of pro-inflammatory cytokines in serum and with a less adequate immune response to infections. Second, obesity is associated with an altered cortisol metabolism possibly related to adrenal insufficiency. This could play an important role in the altered response to surgical stress and postoperative complications in obese subjects. Third, obesity is associated with altered erythrocyte function, including decreased erythrocyte deformability and increased aggregation, factors contributing to an impaired microcirculation. This study has a number of different aims. First, we will compare pre-treatment with the standard low calorie diet with omega-3 fatty acids on liver volume in patients qualified for gastric bypass surgery because of morbid obesity. Second, we will investigate the effect of omega-3 fatty acids on immune function, the low-inflammatory state of adipose tissue, the stress response of obese subjects before and erythrocyte function. Third, we will investigate the effect of gastric bypass surgery by comparing values before surgery with values on the first postoperative day and 6 months after surgery regarding to immunological parameters, stress response and erythrocyte function.
The aim of this study is to develop and identify the most effective strategy to implement PCRPs into daily care. We want to assess the added value of a multi-faceted strategy compared with a single-faceted patient-directed strategy.
Primary Objective: To assess the distribution of IARs by severity grade when LEMTRADA is administered to RRMS patients who will be medicated according to specified algorithm designed to manage infusion associated reactions.
The purpose of this clinical study is to test the hypothesis that market released Cardiac Resynchronization Therapy (CRT) devices which contain the AdaptivCRT® (aCRT) algorithm have a superior outcome compared to standard CRT devices in CRT indicated patients with normal atrio-ventricular (AV) conduction and left bundle branch block (LBBB).
This is a single site, randomized, double-blind, three period cross-over, placebo-controlled, proof of mechanism study in healthy male subjects. The study will investigate whether the directionality of brain activity and connectivity in response to intranasal vasopressin treatment is similar to earlier studies and explores the effect of short-term treatment with RG7314 on functional MRI as a pharmacodynamic marker. While in the scanner, the participants will be asked to perform a face matching task and a Theory of Mind task, among other assessments. Participants' exposure to study drug will be assessed and all participants will receive follow-up examination 1 and 4 weeks after last dose.
