There are about 5161 clinical studies being (or have been) conducted in Norway. 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.
This study is a two phase study that aims to evaluate if low-dose Rituximab maintenance therapy may prolong the the effect of Rituximab in immune thrombocytopenia.
Cluster headache is one of the most painful headaches, characterized by recurring episodes of unilateral, periorbital pain, which is accompanied by autonomic symptoms that seem to be of both sympathetic and parasympathetic origin. The pathophysiology behind the condition is largely unknown, but increasing evidence indicate that the hypothalamus plays a pivotal role. The headache attacks come in clusters or bouts (hence the name) which last up to three months, after which the headache disappears for at least one month. 10-15% have chronic cluster headache. During attacks, the patients have cranial sympathetic hypoactivity and parasympathetic hyperactivity, whereas they have cranial parasympathetic hypoactivity during remission phase. There is an emerging hypothesis that headache attacks are elicited in a state of autonomic hypoarousability, which is also supported by the fact that most cluster attacks occur during the night, when the patients are sleeping. The aim in this project is to study the intercept between the sleep-wake cycle, autonomic tone and the occurrence of headache attacks, by using actigraphy, heart-rate variability and pupillometry. All these methods are well validated, and frequently used in studies on sleep and autonomic function. The study design is that of a case-control model where 15 cluster headache patients will undergo pupillometry, before wearing the actigraph and heart-rate variability-monitor for two weeks, once in cluster bout and once in remission phase. The actigraphy will register nocturnal movement and sleep quality, and headache attacks will be registered by pressing a button on the actigraph. The pupillometry measures pupillary constriction and dilation in response to light, a reflex that is controlled by the autonomic nervous system. The heart-rate variability monitors fluctuations in the heart rate which reflects the sympathovagal balance of cardiac control. All participants will fill out the Pittsburgh Sleep Quality Index before and after registration. In addition, 15 healthy controls will undergo one session of the same examinations. The results of the study will give valuable insight to the pathophysiology of a condition that is very painful and has great impact on the patients' quality of life, and also add knowledge to the relation between headache, sleep and the autonomic nervous system.
The study aims to describe hemodynamic effects of lower body negative pressure (LBNP). 1. If and how changes in cerebral oxygen saturation (StO2) measured by near infrared spectroscopy (NIRS) relate to changes in blood flow in the carotid arteries during progressive LBNP. 2. If and how mean systemic filling pressure (MSFP) can be measured by brief occlusion of blood flow to an arm and if this relates to LBNP-level. 3. If and how pulse pressure variations and photoplethysmographic amplitude variations during positive expiratory pressure (PEP) and continuous positive airway pressure (CPAP) relate to LBNP-level.
This study will compare efficacy and safety of pulmonary vein isolation using a cryoballoon catheter versus a radiofrequency ablation with a contact force sensing catheter for treatment of patients with persistent or longstanding persistent atrial fibrillation.
Neonatal jaundice is a common and most often harmless condition. However, when unrecognized it can be fatal or cause serious brain injury. Three quarters of these deaths are estimated to occur in the poorest regions of the world. The treatment of jaundice, phototherapy, is in most cases easy, low-cost and harmless. The crucial point in reducing the burden of disease is therefore to identify then children at risk. This results in the need for low-cost, reliable and easy-to-use diagnostic tools that can identify newborns with jaundice. Based on previous research on the bio-optics of jaundiced newborn skin, a prototype of a smartphone application has been developed. This prototype will be evaluated in a clinical trial in two hospitals in Norway. A smartphone will be used to take picture of the skin of the newborn, and by using an algorithm an estimate of the bilirubin concentration is made. The results from these estimates will be compared to the bilirubin levels measured in standard blood samples, as well as the results from ordinary transcutaneous measurement devices.
Fitness athletes emphasize the value of staying lean, muscular and defined, and motivates and inspires followers through social media. We want to study the effect of such lifestyle on selected aspects of psychological and physical health in female fitness athletes, and compare the outcomes to a healthy, physically active female population.
This study is designed to evaluate the long-term safety and efficacy of Upadacitinib in participants with ulcerative colitis (UC) who have not responded at the end of the induction period in Study M14-234 Substudy 1, who have had loss of response during the maintenance period of Study M14-234 Substudy 3, or who have successfully completed Study M14-234 Substudy 3.
To explore the experiences of individuals with musculoskeletal disorders (MSDs) who have participated in return-to-work group programmes (RTW-GPs) and see how the programmes could strengthen their work ability.
The main goal of this study is to evaluate the ability of a single administration of tocilizumab to reduce myocardial damage in patients presenting with an acute ST-segment elevation myocardial infarction (STEMI). Secondary objectives are to assess the impact of treatment on: (i) final infarct size, (ii) left ventricular size and function, (iii) inflammation, (iv) extracellular matrix remodeling, (v) lipid parameters, (vi) platelet activation and additional pro- and anti-thrombotic parameters, and (vii) study drug safety and tolerability.
This is a multi center, phase I pilot study of sequential ONCOS-102 and pembrolizumab in patients with advanced or unresectable melanoma progressing after PD1 blockade. The primary objective of the study is to determine the safety of sequential treatment with ONCOS-102 followed by pembrolizumab. The protocol aims to enroll patients into two cohorts: Part I: up to 12 patients will receive sequential treatment with ONCOS-102 followed by pembrolizumab. Part II: up to 12 patients will receive an initial treatment phase with ONCOS-102 followed by a treatment phase with ONCOS-102 in combination with pembrolizumab.
