There are about 9336 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.
This study is an interventional, randomized, multinational, multicenter, double-blind, phase 2 study with a follow-up period of circa 12 months. The intension of this clinical trial is to investigate the long-term sequelae (named Long COVID syndrome; post COVID or PASC) of an infection with Corona Virus Type 2 that has resulted in a condition known as Severe Acute Respiratory Syndrome Corona Virus Type 2 (SARS-CoV-2). The purpose of this study is to evaluate the efficacy and safety of BC 007 as a treatment for long-lasting COVID-symptoms in patients who were neither intubated nor supported with extracorporeal blood oxygenation (ECMO) during their acute COVID-19 infection. The study drug acts by neutralizing functional autoantibodies directed against G-protein coupled receptors (GPCRs). Neutralization of the autoantibodies is expected to induce a beneficial effect on symptoms typically seen in patients with long COVID syndrome. Functional autoantibodies are proteins belonging to the class of G-type immunoglobulins that can be synthesized by activation of the immune system and can induce various pathogenic activities by binding to one of the extracellular loops of G-proteins (GPCR-AAB). The study consists of a screening phase of up to 35 days, treatment (two administrations by intravenous infusion at two-week intervals either with the study drug (BC 007) or with placebo (NaCl 0.9%), with an initial follow-up period of 15 days after each administration and an extended follow-up period of 330 days. Patients are required to visit the study center for follow-up visits at specified intervals. For the entire study duration of 395 days from screening to the end of the study, 11 site visits are planned.
The goal of this study is to develop a prognostic score for ischemic posterior circulation strokes, based on our previous work on with the ASTRAL scores (Acute STroke Registry and Analysis of Lausanne) on overall stroke prognosis, intracranial occlusion, recanalization and stroke recurrences. The main question it aims to answer is the modified Rankin score in 3 months after the event. Participants will be patients with acute ischemic stroke of the posterior circulation with mRS priot to event <3. All the data will be collected retrospectively from patients included in the ASTRAL registry between January 2003 and December 2021. The ASTRAL registry will be used as the derivation cohort of the score. Demographics, acute glucose, NIHSS score and acute imaging of each participant will be used from the derivation cohort in order to create an integer-based prognostic score. After internal validation, we plan to validate the score in external stroke registries to show its validity.
The study is being conducted to understand how the medicine, semaglutide, affects the immune system and other biological processes in people with Alzheimer's disease. Semaglutide is a medicine that doctors can prescribe in some countries for the treatment of type 2 diabetes and excess body weight. This study will help us understand whether semaglutide can also be used for the treatment of Alzheimer's disease. The study will last for about 77 weeks. In the first 12 weeks of treatment, participants will either get semaglutide (active medicine) or placebo (inactive dummy medicine). Which treatment participants get is decided by chance. In the following 52 weeks of treatment, all participants taking part in the study will get semaglutide. Participants must have a study partner, who is willing to take part in the study. Participants will get study medicine in a pen injector. The study partner will need to inject the study medicine into the skin of participant's stomach, thigh or upper arm once every week.
The study will explore the performance of the CDMS (Cryo Detector Mass Spectrometer) method in measuring SF (serum ferritin) in human serum of healthy individuals. This will be the first experience of testing SF with this method using biologic material of human origin.
All enrolled participants will be randomized to 3 cohorts with 8 participants each and will receive BAP5191 and placebo topically on a square of 121 cm2 each in the left and right scapula region daily for 28 days, with a 28-d safety follow-up. The squares will be covered with a semi-occlusive patch. The doses will escalate from Cohort 1 to Cohort 2 to Cohort 3.
Tumour lysis syndrome (TLS) occurs as a consequence of the rapid destruction of malignant cells, spontaneously and/or in response to cytotoxic agents and immunotherapies. TLS is a feature of highly proliferative diseases with heavy tumor burden, such as high-grade non-Hodgkin lymphomas (NHL, typically Burkitt's lymphoma). We evaluated fractionating first rituximab dose to prevent TLS in a real-life B-cell NHL cohort of patients treated at University Hospital of Geneva between 2010 and 2020.
This retrospective monocentric study aims to investigate whether a low muscle mass at ICU admission and its loss over the ICU stay predicts mortality, and in what proportion we can counteract it by nutritional support.
This study is designed as a long-term extension to Study APL2-C3G-310, and is being conducted to establish the long-term safety and efficacy of pegcetacoplan in patients with C3 glomerulopathy (C3G) or immune-complex membranoproliferative glomerulonephritis (IC-MPGN).
Supportive periodontal therapy (SPT) succeeds the active phase of periodontal therapy. SPT includes repeated supra- and subgingival scaling and root planing (SRP) at all sites with bleeding on probing and pocket depths ≥ 4-5 mm. Despite the fact that this treatment approach has been proven to be extremely successful, on a long-time basis, it is associated with substantial hard tissue loss (i.e. root cementum and dentin) that may lead to an increase in hypersensitivity, weakening of the tooth and even endodontic complications. Therefore, a novel treatment concept (Guided Biofilm Management or GBM) consisting of removal of all soft supra- and subgingival bacterial deposits by means of an erythritol powder air-polishing, followed by the local, precise removal of supra and subgingival hard deposits (e.g. calculus) and subsequent use of another sub- and supragingival erythritol powder air-polishing, has been introduced. Here, the investigators will compare this novel concept (GBM) with the conventional care during SPT using hand curettes.
The aim of the study is to compare two different locoregional techniques in VATS.
