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.
Systemic Lupus Erythematosus (SLE) is an immune-mediated disease associated with inflammation of multiple organ systems. This study will assess how safe and effective upadacitinib is in treating adult participants with moderately to severely active SLE. Adverse events and change in the disease activity will be assessed. Upadacitinib is an approved drug for rheumatoid arthritis, psoriatic arthritis, and axial spondylarthritis and is being developed for the treatment of SLE. This study is "double-blinded", which means that neither the trial participants nor the study doctors will know who will be given upadacitinib and who will be given placebo (does not contain treatment drug) . This study comprised of 3 sub studies. In Study 1 and Study 2, study doctors put the participants in 1 of the 2 groups, called treatment arms. Each group receives a different treatment. There is a 1 in 2 chance that participants will be assigned to placebo. Eligible participants from Study 1 and Study 2 will enter Study 3 at week 52 to receive specific doses of upadacitinib based on their disease activity and their original treatment assignment in Study 1 or 2. Approximately 500 participants diagnosed with SLE will be enrolled in each of the Study 1 and Study 2 in approximately 320 sites across the world. Participants will receive oral tablets of upadacitinib or matching placebo once daily for 52 weeks in Study 1 and Study 2. Eligible participants from Study 1 and Study 2 will receive oral tablets of upadacitinib once daily for 52 weeks in Study 3. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, checking for side effects and completing questionnaires.
Research about patients with alcohol use disorder has shown that task-related brain activation patterns as well as resting-state connectivity (measured with functional magnetic resonance imaging) change with clinical parameters such as the extent of craving and duration of abstinence during treatment. These brain activation alterations are related to treatment success. Although an imbalance between increased cue-reactivity and impaired counteracting inhibitory control processes are at the core of most neuropsychological conceptualizations of alcohol use disorder, the direct interaction between these two processes has not yet been investigated. Therefore, the investigators aim to study patients with alcohol use disorder in an ultra-high-field 7 Tesla magnetic resonance imaging scanner to identify fine-grained activation and connectivity patterns. The investigators would like to improve the knowledge of the interplay between the brain networks for inhibition and cue-reactivity, as well as to explore its influence on craving and treatment success. The investigators hypothesize that a more pronounced negative relationship between increased cue-reactivity and reduced inhibitory control processes in the brain is linked to higher craving and worse relapse probability.
This study assesses the feasibility of digital data collection for a randomized controlled trial in a quaternary pediatric intensive care unit and the effect of two commonly used mechanical ventilation modes on gas exchange (CO2) in children over 2 days after randomization. This is a single-center, open-labelled, randomized controlled trial with two parallel 1:1 treatment arms: pressure controlled (PC) vs pressure-regulated volume controlled (PRVC) mechanical ventilation modes. Use to routine digital data is essential to enable health learning systems and to provide rapid clinical trials readiness, as the pandemic has demonstrated. Despite availability of data to perform digital trials in PICU settings, these are yet scarcely done.
Attention deficit hyperactivity disorder (ADHD) is characterized by difficulties paying attention, poor impulse control, and hyperactive behaviors. It is associated with several health and social detrimental outcomes and leads to increased risks of criminality and recidivism. However, to date, ADHD treatment has been neglected in prison. This project will test the efficacy of ADHD treatment using a randomized controlled trial.
Crohn's disease (CD) is an incurable chronic inflammatory disorder of the gastrointestinal tract. This study will assess how safe and effective risankizumab is in treating moderately to severely active CD in real world. Adverse events and change in disease activity will be assessed. Risankizumab is a drug approved for the treatment of CD. All study participants will receive risankizumab as prescribed by their study doctor in accordance with approved local label. Approximately 1000 participants will be enrolled worldwide. Participants will receive risankizumab as prescribed by their physician according to their routine clinical practice and local label. Participants will be followed for up to 36 months. There is expected to be no additional burden for participants in this trial. Study visits may be conducted on-site or virtually as per standard of care.
SENSE-II/AROUSE is a prospective, multicenter registry for patients treated for SE. The primary objective is to document patients and SE characteristics, treatment modalities, EEG features, and outcome of consecutive adults admitted fir SE treatment in each of the participating centers and to identify predictors of outcome and refractoriness.
To evaluate the safety, tolerability, and DLTs and determine the MTD and/or RDE(s) of INCA33890 in participants with select advanced or metastatic solid tumors.
Significant advances in dedicated materials and techniques along with increased operator experience led to a significant increment in procedural success rate of peripheral endovascular interventions, exceeding 90% in expert hands with reported low procedural complication rates. However, there are still lack of data on procedural outcomes, in-hospital complications, and resource utilization on treatment of (complex) lesions in the femoral, popliteal and infrapopliteal artery in the real-world condition in Europe.
Sphingosine 1-Phosphate (S1P) receptor modulators (S1PRMs) are part of the evolving treatment landscape of Multiple Sclerosis (MS) immunotherapies. They target the G-protein coupled S1P receptor, among other localizations expressed at the surface of lymphocytes. Binding as a functional antagonist leads to internalization of the receptor and therefore lymphocyte sequestration in the secondary lymphoid organs. The first S1PRM approved was fingolimod. More recently newer generation S1PRMs like ozanimod have been approved, which possess differences in receptor affinities, pharmacokinetics and indications (including Secondary Progressive MS or Ulcerative Colitis). Several retrospective analyses have shown that, upon cessation of fingolimod, pronounced relapse of the MS-disease called "rebound disease activity" may occur. Indeed, these relapses, sometimes with considerable severity, take place in up to 10% of patients. The risk of rebound disease of the newer generation S1PRM are not well defined. Although of utmost importance, predictive biomarkers of treatment efficacy in general and in special circumstances, e.g. an impending rebound when S1PRM cessation is planned, are scarce. In this prospective, exploratory observational study, we aim to investigate the predictive potential of the lymphocytic S1PR1 and 5 expression prior to treatment initiation with the newer generation S1PRM ozanimod on the future disease activity ("on treatment" part). Additionally, in a post-treatment part ("off treatment"), the incidence of rebound disease and the predictive potential of the lymphocytic S1PR1 and 5 expression will be examined in patients, where ozanimod has to be stopped due to clinical reasons. T and B cells from patient blood samples obtained prior to treatment start/cessation and 3 - 6 months after start/cessation will be isolated and S1PR1 and 5 staining intensity will be assessed by flow cytometry (FACS). Clinical assessments (relapse assessment, EDSS, medical history etc.) will be performed at every visit and MRI evaluation, following our standard clinical and MRI MS protocol. MRI disease activity will serve as the primary endpoint for both study groups. The relationship between the flow cytometric staining intensity and the defined endpoints will be assessed statistically by using comparative statistical approaches and multivariable regression analysis where needed for both time points. The data collected will correlate the expression pattern of S1P receptors by T and B lymphocytes to the proxy of paraclinical activity as predictive biomarkers for disease activity on treatment and after treatment discontinuation.
This is a monocentric, single blind, interventional, single arm study. It is designed to compare the rates of detection of hepatocellular carcinoma (HCC) by ultrasound (US) used in clinical routine vs. abbreviated magnetic resonance imaging (AMRI). The hypothesis is that dynamic AMRI with extracellular contrast agent injection has a higher patient-level detection rate of HCC than screening US and non-contrast AMRI. Interested and eligible patients will be enrolled and undergo HCC screening rounds including US +/- contrast-enhanced US (clinical routine) and screening MRI within the same week bi-annually.
