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.
The purpose of this trial is to generate clinical evidence on valve safety and performance of self-expanding (SE) versus balloon-expandable (BE) transcatheter aortic valve replacement (TAVR) in subjects with a small aortic annulus and symptomatic severe native aortic stenosis. Additionally, a stress echocardiography sub-study will be conducted as part of the SMART Trial at select sites. The purpose of the sub-study is to evaluate performance of SE versus BE TAVR in subjects with a small aortic annulus and symptomatic severe native aortic stenosis after undergoing exercise stress echocardiographic testing.
Delirious patients often suffer from sleep disturbances such as insomnia, sleep fragmentation, daytime somnolence, and reversal of sleep-wake rhythms. There is evidence, that patients suffering from hyperactive, as well as hypoactive and mixed delirium suffer from disturbed circadian rhythm. The investigators hypothesize that the circadian melatonin profile in critically ill delirious patients measured at two-hourly intervals deviates significantly in terms of phase, width and amplitude from non-delirious critically ill patients with similar age and SOFA (Sequential Organ Failure Assessment) score.
The glutamate system is emerging as target for the development of novel antidepressant medication, in particular compounds modulating the NMDA receptor. While the NMDA receptor antagonist ketamine is an effective option for many treatment-restistant patients, it is also accompanied by dissociative and cognitive effects and also bears the risk to develop addiction, side effects that are significantly restricting its clinical utility. There is now compelling evidence of the antidepressant potential of D-serine, a NMDAR co-agonist. Compared to ketamine, D-serine goes along without any psychotomimetic effects or other side effects and thus might be a prom-ising novel antidepressant. This study represents the first randomized control trial to test the efficacy of D-serine as an adjuvant therapy in patients with depression and thereby adds to re-cent efforts to establish novel glutamatergic antidepressants. Besides clinical measures, this study also explores the biological mechanisms underlying D-serine's clinical effect.
The purpose of this study is to evaluate the efficacy and safety of 177Lu-PSMA-617 in combination with Standard of Care, versus Standard of Care alone, in adult male patients with mHSPC. In this study, the SoC is defined as a combination of Androgen Receptor Directed Therapy + Androgen Deprivation Therapy. Approximately 1126 patients will be randomized in this study. As of 31-Jan-2024, 1144 participants have been enrolled in 20 countries.
Invasive mold infections (IMI) mainly affect patients with hematologic malignancies receiving intensive chemotherapy or after hematopoietic stem cell transplantation (HSCT). Prolonged neutropenia after remission induction chemotherapy (>10 days duration) and continuous immunosuppression in the context of prevention or therapy of graft versus host disease (GVHD) for HSCT recipients (first 100 days post-transplantation and thereafter if GVHD is present) are considered as periods at high risk of IMI. Posaconazole prophylaxis is prescribed according to current guidelines to reduce the occurrence of IMI. Nevertheless, breakthrough IMI (bIMI), i.e. IMI occurring under mold-active prophylaxis, are still observed. The investigators hypothesized that the epidemiology of bIMI (under posaconazole prophylaxis) differs from that of IMI occurring in the absence of mold-active antifungal prophylaxis. Because bIMI are rare events since the introduction of posaconazole prophylaxis, epidemiological data of bIMI are scarce. This study aims to i) describe the epidemiology, clinical features, treatment and outcome of bIMI, ii) assess the causes of bIMI, iii) determine potential risk factors associated with the developllement of bIMI iv) assess the impact of bIMI on overall mortality. Design Retrospective and prospective, observational, case-control, multicenter, international study. The retrospective part will enroll previously identified bIMI cases and control cases (1:2) over the last five years: October 1st 2015 to September 30st 2020. The prospective part will enroll bIMI cases and control cases (1:2) occurring over a two-year period: October 1st 2020 to September 30st 2022. Setting The aim is to enroll 10 to 15 European centers with dedicated units for hematologic cancer patients. Currently, six centers have confirmed their participation (from Switzerland and Germany). Study Population Adult (≥ 18 years old) patients with a hematologic malignancy receiving posaconazole prophylaxis during induction, consolidation or re-induction chemotherapy or after HSCT. Cases : patients receiving posaconazole prophylaxis for at least 7 days and diagnosed with bIMI proven or probable according to EORTC-MSGERC. Controls: patients receiving posaconazole prophylaxis for at least 7 days, without diagnosis of bIMI possible, probable or proven according to EORTC-MSGERC. The objective is to enroll about 100 bIMI cases and 200 controls.
In spite of the considerable technical difficulties, several publications confirm the potential that T1-maps and MRI to characterize pathological changes in lung tissue. However, existing literature still cannot provide a final evaluation of the presented methods. Study participants won't have any disadvantage in participating the study since all of them undergo next to the MRI-Scan also the two standard methods: CT and lung function test. In this study the value of chest MR compared to CT and LFT in the evaluation of morphological lung changes and their correlation to lung ventilation and perfusion will be evaluated.
Prevalence of NTM diseases has been increasing regularly over the past 30 years in industrialized countries Although NTM are identified worldwide, there are important geographical disparities as to the relative prevalence of NTM species There are no data covering the ecology of NTM in Switzerland. Because of the progressive increase in NTM clinical cases in area Geneva(as noted in other industrialized countries), reporting the specific NTM distribution is important and relevant. In this study, the investigators aimed to: 1/ describe the relative prevalence of NTM species in clinical samples analyzed in the Geneva area, covering ca 500'000 inhabitants over a 5-year period; 2/ determine how many culture positive patients were treated; and 3/ specify the clinical sites involved.
This study will assess whether switching participants who have benefitted from mepolizumab or benralizumab to GSK3511294 (Depemokimab) is non-inferior to maintaining current treatment on the annualized rate of clinically significant exacerbations in participants with severe asthma with an eosinophilic phenotype. Throughout the study, all participants will continue their non-biologic Baseline standard of care (SoC) asthma treatment.
The iLIVE medication study is a before-after study where medication optimisation of patients with an estimated life expectancy of six months is investigated. The investigators will include 400 patients in 3 countries. The primary outcome is an assessment of the quality of life of patients, four weeks after baseline assessment
Sleep slow waves (SSW) and the pathophysiological mechanisms of spike generation in patients with epilepsy are tightly linked. SSW are cortically generated oscillations (~1 Hz) alternating between a hyperpolarized down-state (neuronal silence) and a depolarized up-state (neuronal firing). It has been shown experimentally that with increasing synchrony of slow neuronal oscillations, spike wave occurrence is facilitated. Auditory stimulation applied in correspondence to the SSW "up-phase" may increase the amplitude of the following SSW. Contrarywise, tones applied at the SSW "down-phase" may have a disruptive effect on SSW. Participants: Patients with epilepsy with epileptic discharges in their sleep EEG, as well as healthy controls Objective: Characterizing the effects of down-phase-targeted auditory stimulation on behavior and sleep EEG characteristics and determine whether the changes in sleep EEG characteristics are associated with the changes in behavior and wake EEG characteristics.
