There are about 9403 clinical studies being (or have been) conducted in Switzerland. 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.
Transcatheter aortic valve implantation (TAVI) has emerged as a valuable minimal-invasive treatment option in patients with symptomatic severe aortic valve (AV) stenosis at prohibitive or increased risk for conventional open-heart surgery. Recent randomized clinical trials reported a large treatment effect of TAVI over medical treatment among inoperable patients and similar or superior outcomes compared with surgical aortic valve replacement in high to intermediate risk patients. However, atrio-ventricular conduction disturbances and arrhythmias (in particular atrial fibrillation) before, during or after TAVI remain a matter of concern as they have important consequences. The objective of this study is to investigate the incidence, nature and prognostic significance of AV-conduction disturbances and arrhythmias among patients with severe, symptomatic aortic stenosis undergoing TAVI before, during and after the procedure using a small implantable cardiac monitoring system (ICM; Medtronic REVEAL LinQTM). One hundred patients will be enrolled in this study. Prior to TAVI (at least 4 weeks), at the time of preprocedural hemodynamic and anatomical assessment, the ICM will be inserted under the skin of the chest under local anesthesia. The device will be interrogated just prior to readmission for TAVI and thereafter at 1, 3, 6, and 12 months of follow-up. The incidence of symptomatic as well as silent brady- and tachyarrhythmias will be recorded, and its impact on medical and device treatment as well as clinical outcomes analyzed. The present study will provide information about the actual incidence and impact of symptomatic and silent arrhythmias and AV-conduction disturbances among patients with severe, symptomatic aortic stenosis undergoing TAVI. Specifically, the study estimate the burden of arrhythmias before TAVI and to accurately determine the incidence of new onset atrial fibrillation and complete AV-block within 12 months after the procedure. Identifying patients at risk for AV- conduction abnormalities, atrial fibrillation (AF), and non-sustained or sustained ventricular arrhythmias may guide future preventive measures, medical treatment and improve patients outcomes after TAVI.
The main objectives of the study are to evaluate the acceptance into operating flow, performance and safety of the AQrate Robotic Assisted System during the spinal fusion surgery
Pulmonary Hypertension (PH) is a serious disease with a dismal prognosis when left untreated. Advances in medical therapy have improved survival according to recent registries and systematic reviews, but are associated with high healthcare costs. Earlier studies in Heidelberg, Germany showed good evidence for the effect of exercise training on improving exercise performance, quality of life and pulmonary hemodynamics in patients with pulmonary hypertension. The main objectives of the present project are: 1. to investigate the quality of the implementation of a standardized 3 week in-hospital exercise training program on markers of outcome and disease severity in PH-patients in Switzerland immediately after training and after 3 and 12 month. 2. to look whether training with hyperoxia vs. standard care might be more effective. This is a multicentre, randomized parallel-group trial where the intervention rehabilitation is delayed in one group so that they can serve as standard care controls for the others. In a nested single-centre randomized-controlled trial patent will additionally be randomized to receive either usual rehabilitation (UR) or rehabilitation with standardized supplemental oxygen therapy (SSOT) during nights and ergometer training. Patients will receive a PH specific rehabilitation program during 3 weeks followed by an instructed home-based training program for 12 weeks. Patients who are not already under long-term oxygen therapy (LTOT) due to daytime hypoxemia will additionally be randomized to receive standardized supplemental oxygen therapy (SSOT) during training and nights upon written informed consent.
The objective of this clinical trial is to compare the efficacy and safety of an initial triple oral treatment regimen (macitentan, tadalafil, selexipag) versus an initial dual oral treatment regimen (macitentan, tadalafil, placebo) in newly diagnosed, treatment-naïve patients with pulmonary arterial hypertension.
The purpose of this study is to determine how the dopamine and opioid system is involved in reward processing, specifically in cue-induced reward responding and reward impulsivity, using dopamine and opioid receptor antagonists in healthy participants. The investigators predict that particularly the dopamine challenge should alter cue-induced reward responding and reward impulsivity. Such effects would be of high interest for the treatment of disorders which involve impairments of reward processing such as addiction.
To assess whether a rivaroxaban-based anticoagulation strategy, following successful TAVR, compared to an antiplatelet-based strategy, is superior in reducing death or first thromboembolic events (DTE). To assess the primary bleeding events (PBE) of the rivaroxaban-based strategy compared to an antiplatelet-based strategy, following TAVR.
Optical Coherence Tomography (OCT) is an established non-invasive medical imaging technique ophthalmologists use to diagnose and monitor retinal diseases such as age-related macular degeneration (AMD). This study assesses the scanning performance of a newly developed sparse OCT retina scanner that is smaller and more compact than most commercially available medical OCT systems. The prototype device was developed at Artorg Center Bern and Berner Fachhochschule Biel. In this study the device is first tested on human eyes. The scanning performance is compared to a reference device. Additionally patient feedback during the examination is acquired. The findings of this study are used to improve the software and the ergonomics of the investigational device.
This study aimed to determine the efficacy and safety of QAW039 150 mg and QAW039 450 mg, compared with placebo, when added to GINA (Global Initiative for Asthma) steps 4 and 5 standard-of- care (SoC) asthma therapy (GINA 2016) in the following two populations: - patient with inadequately controlled severe asthma and high eosinophil counts at baseline (eosinophil count at Visit 1 ≥250 cells/ µl) (sub-population) - patients with inadequately controlled severe asthma (overall study population) Inadequate control is defined as partly controlled or uncontrolled asthma (GINA 2016).
Integration of the REM-verification within the fitting workflow will enable the hearing care professional to easily run real ear measurements. The purpose of the two study parts is to prove that an integrated cooperative system, consisting of fitting software and measurement system, matches desired responses for certain stimuli faster, more reliably and more precisely at the ear drums of hearing instrument wearers than current best practice processes.
