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.
The main aim of this study is to check if repeated subcutaneous (SC) injections of lanadelumab can prevent angioedema attacks in teenagers and adults with non-histaminergic angioedema with normal C1-INH. Another aim is to check if they tolerate the repeated SC injections. Participants will receive a SC injection of lanadelumab every two weeks for 26 weeks. The first two doses of lanadelumab will be given at the study clinic. Once a participant (and/or parent/caregiver) has been appropriately trained, lanadelumab can be self-injected. Visits to the study clinic are planned for the first, third and fourth week and then every 4 weeks.
Deprescribing, the process of safely reducing or discontinuing unnecessary or harmful medication, has the potential to decrease polypharmacy and improve health outcomes. In this study a structured implicit algorithm, focusing on both extrinsic medication factors (eg change in disease) and intrinsic patient factors (eg. pill burden) will be used.
Background: Reliable patient reported outcome measures (PROM's) for symptom assessment in functional dyspepsia (FD) are essential in order to evaluate dyspeptic symptoms, identify potential symptom triggers and optimize therapeutic strategies, since biological markers are unavailable. Currently used symptom assessment methods, i.e. end-of-day or end-of-week questionnaires, have considerable limitations. The Experience Sampling Method (ESM), an electronic questioning method characterized by random and repeated, momentary assessments in the subject's current state and environment, might overcome these limitations. The aim of this study is to assess the validity and reliability of an FD-specific electronic patient-reported outcome measure (ePRO), based on the Experience Sampling Method-principle, for symptom assessment and identification of symptom triggers in patients with functional dyspepsia. Objective: The aim of this study is to assess the validity and reliability of an FD-specific electronic patient-reported outcome measure (ePRO), based on the Experience Sampling Method-principle, for symptom assessment and identification of symptom triggers in patients with functional dyspepsia. In order to measure this, internal consistency, test-retest reliability, concurrent validity and the accuracy to differentiate between dyspeptic patients and healthy controls of the developed ePRO will be assessed. In addition, to objectify specific triggers for the onset of gastrointestinal symptoms in dyspepsia, using the FD-specific ESM tool.
Prospective combined clinical validation of an algorithmic calculated mean systemic filling pressure (Pms-Nav) with the gold standard for Pms (Pms calculated from venous return curves during inspiratory hold procedures with incremental airway pressures; Pms-Insp). Secondary correlation between invasive cardiac output measurement versus 3D TOE and carotid echo doppler measured cardiac output.
Pain is a nociceptive somatosensory process that can arise as a debilitating and chronic symptom in various diseases or following an injury. How pain is experienced can vary widely within and across individuals, and can be shaped by cognitive processes such as learning. Nocebo effects, negative changes in symptom severity attributed to learned outcome-expectations, demonstrate how learning processes can be detrimental for the experience of pain. Research to date has produced inconclusive findings regarding the electrophysiological correlates on nocebo effects. The few studies that have applied electroencephalography (EEG) in this field have pointed towards a potential involvement of alpha-band activity, but the direction of this involvement remains unclear. For example, an EEG study of conditioned nocebo hyperalgesia found a pre to post increase in resting state alpha band power that was correlated with pain catastrophizing scores and not with the magnitude of the nocebo effect. Later, other studies also found pre to post changes in alpha band power, however, these changes were correlated with the magnitude of nocebo effects and not pain catastrophizing. Given the discrepancy in findings, in this study the investigators plan to primarily investigate whether EEG components predict the magnitude of nocebo responses to thermal-pain stimuli. The investigators will also explore electrophysiological correlates during pain anticipation and whether nocebo responses would be significantly related to spectral and temporal EEG biomarkers. This study will utilize a validated model of instructional and associative learning methods (i.e., negative suggestions and classical conditioning, respectively) to experimentally induce nocebo effects on heat-evoked pain. Developing objective, brain-derived markers for nocebo responses, or the detection of individuals most susceptible to nocebo hyperalgesia, will aid in the comprehensive management of pain. This study is conducted at Leiden University.
The study is a prospective, multi-center, non-randomized, unblinded worldwide pre-market clinical study. The purpose of the study is to provide data demonstrating the safety and effectiveness of the PulseSelectâ„¢ PFA System for the treatment of atrial fibrillation (AF). The study will also provide first in human insights into clinical safety and device function of the PulseSelect PFA System for pulmonary vein isolation (PVI) as a treatment for AF. To this end, the clinical study has been designed into phases (Pilot and Pivotal), with each phase comprising a separate data set that will be analyzed and reported on per the below objectives.
Nocebo hyperalgesia is characterized by adverse pain outcomes, induced by patients' expectations. In the lab, nocebo effects are commonly studied via classical conditioning, a method that employs pairings of neutral cues/treatments with different pain intensities to install differential pain-related expectations. In such conditioning experiments, participants are typically taught that a (sham) treatment exaggerates their pain, by surreptitiously administering high intensity (e.g. pain) stimuli in combination with this treatment. Verbal suggestions are also often used to inform participants of the supposed adverse effects of such treatments. In nocebo studies, higher pain levels and suggestions that are of more threatening nature may induce fear, thereby adding a crucial element to the experimental manipulation. Since nocebo effects are hypothesized to arise in clinical settings due to a combination of several psychological and cognitive mechanisms, it is important to study the role that factors such as higher pain levels, conditioned pain-related fear, or more threatening verbal suggestions may play in the formation of nocebo hyperalgesia. To date, no studies have focused on the fear-inducing effect that different pain intensities or verbal threat suggestions may have and how this fear, in turn, may strengthen the acquisition of nocebo effects. This study aims to investigate whether higher pain intensity or higher pain-related fear induced via threatening suggestions facilitate the acquisition and hinder subsequent extinction of nocebo hyperalgesia. This study will be conducted at Leiden University.
The main objective of this study is to assess safety, tolerability, and pharmacokinetics (PK) of ABBV-368 plus tilsotolimod; ABBV-368 plus tilsotolimod and nab-paclitaxel; and ABBV-368 plus tilsotolimod, nab-paclitaxel, and ABBV-181 in participants with recurrent/metastatic (R/M) head and neck squamous cell carcinoma (HNSCC).
This is a study for adults (18-75 years) who have successfully completed treatment either with Dupilumab or with Upadacitinib in the study M16-046. At the end of M16-046, they have the option to receive Upadacitinib with a duration of 52 weeks beyond the timeframe of Study M16-046. There will be a 30 day follow-up visit after the treatment period is completed. Main objective of this study is to assess long-term safety, tolerability and efficacy of upadacitinib in participants with moderate to severe atopic dermatitis who successfully completed treatment in the study M16-046.
The investigators intended for this study to deliver the "proof-of-concept" that locally administered pilocarpine drops in two doses are effective in a population of elderly (aged ≥ 70 years) with xerostomia at the expense of limited adverse events. To this end, the study aims to quantify the effect size of pilocarpine in two different dosages. In case the investigators observe clinically meaningful changes in xerostomia through measured NRS, a sufficiently-powered RCT will be prepared to compare pilocarpine to placebo.
