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 study is designed to compare the efficacy of asciminib 80 mg QD versus Investigator selected TKI for the treatment of newly diagnosed, previously untreated patients with Ph+ CML-CP. The Investigator selected TKI will be one of the following treatment options for first-line treatment of CML-CP - imatinib 400 mg QD or nilotinib 300 mg BID or dasatinib 100 mg QD or bosutinib 400 mg QD.
This study is designed to compare the safety and effectiveness of blood clot (thrombus) removal in subjects presenting with ST-segment elevation myocardial infarction (STEMI) with the enVast coronary system versus conventional intervention.
In this Phase 4, open-label trial, participants of the ACTIV-3/TICO clinical trial at selected sites who received certain pre-specified blinded investigational agents or placebo as part of that trial, and who have since achieved sustained recovery, and who are still [TICO assignment] blinded and who are still within 28 to 90 days after initial TICO randomization, will be randomized in this 2x2 factorial design to one of four groups: (i) immediate versus 12 week deferral of first dose administration and also (ii) one dose only, versus two doses to be given 4 weeks apart of the Moderna mRNA-1273 or the Pfizer BNT162b2 vaccine (mRNA vaccines). Choice of Moderna or Pfizer vaccine is determined based on availability at the site. The choice is individual, although participants vaccinated twice should receive the same type of vaccine for both injections. The primary objectives of this 2x2 factorial design are (i) to estimate the difference in neutralizing antibody (NAb) response to the mRNA vaccine from baseline to Week 48 among participants vaccinated early versus deferred, and (ii) to estimate the difference in NAb response to this vaccine among participants vaccinated once versus twice. The primary analyses will be carried out in participants randomized to placebo in TICO. Analyses will also be carried out for those who receive the investigational agent(s) studied in TICO. A key secondary objective is to ascertain the effect, if any, of SARS-CoV-2 monoclonal antibodies, and other interventions that have been studied in hospitalized COVID-19 subjects, on natural and vaccine-induced immunity. Participants will remain blinded to the interventions received in the ACTIV-3/TICO study, however allocation to the timing of vaccination and to one or two vaccinations in this (VATICO) study is not blinded.
This study assessed whether transanal TME in patients with rectal cancer is superior to open, laparoscopic, and robotic TME (abdominal TME (abTME)) regarding oncological outcome, postoperative morbidity and 90-day mortality.
The objective of this clinical trial is to evaluate the safety of the SPECTRALIS CENTAURUS device (HuCE-optoLab, BFH TI, Biel, CH) in a clinical setting on patients with retinal diseases.
In patients with early to mid-stage knee osteoarthritis (OA), a conservative treatment is indicated. In medial knee OA (when mainly the medial compartment of the knee is affected by OA), lateral wedge insoles have been promoted as cost effective and simple solution. However, clinical trials report conflicting results, with some reporting no benefit while others reported a small decrease in knee pain. Recent studies reported medial OA patients to have a tendency to a plano-valgus foot deformity, which is associated with a varus lower limb alignment and an internal rotation of the tibia. Some authors thus proposed the correction of plano-valgus deformity with foot deformity correcting insoles instead of lateral wedge insoles. Until today, only one study investigated the effect of foot deformity correcting insoles (e.g. with medial arch support) as alternative to lateral wedge insoles and reported encouraging results. However, they used lateral wedge insoles with custom arch support instead of foot deformity correcting customized insoles along (without lateral wedge). Furthermore, they did not perform any biomechanical analyses. The primary object of this study is to compare the effect of foot deformity correcting insoles for plano-valgus foot deformities and lateral wedge insoles on knee load distribution, knee pain and patient reported outcome measures in early to mid-stage medial knee OA patients after 6 and 12 months.
Accurate movement execution is a result of a complex interplay between various muscle groups whose activity is controlled by different areas of the central nervous system. Besides the corticospinal system, the phylogenetically old reticulospinal system is a key motor system controlling different elementary movements including posture, locomotion and reaching across all mammals. In contrast to the extensively investigated corticospinal system, there is only sparse knowledge on the motor physiology of the functionally important reticulospinal system in humans. Reticulospinal motor control can be assessed with the StartReact paradigm which is based on the activation of reticulospinal motor circuitries by startling acoustic stimuli. The StartReact phenomenon is characterized by a shortening in movement reaction time which is mediated by a startle-triggered, early release of a planned motor program by the reticulospinal system. Thus, StartReact is a unique tool to examine reticulospinal involvement on human motor control under physiological and pathological conditions. StartReact assessments will be supplemented by comprehensive 3-D kinematic analysis and muscle activity recordings (i.e. electromyography) to gain quantitative insights into reticulospinal movement control. The first objective of this clinical study is to gain more insights into the mechanisms underlying StartReact and to advance the knowledge on reticulo-spinal motor physiology regarding different movement tasks (i.e. simple single-joint movements, complex multi-joint movements and bilateral hand movements) in healthy subjects. The findings of these experiments will provide new insights into proximal-distal, flexor-extensor and upper-lower extremity gradients in reticulospinal motor control of healthy subjects. Moreover, the results will expand the StartReact paradigm to complex, functionally more relevant movements (i.e. reaching and stepping tasks requiring endpoint accuracy; co-operative, bilateral hand movements) for which the involvement of the reticulo-spinal system is not yet understood. The second goal of this project is to use the StartReact paradigm to shed more light onto the role of reticulospinal plasticity in functional recovery of patients with spinal cord injury (SCI). Whereas preclinical findings emphasize a remarkable potential of the reticulospinal system for neuroplastic adaptations underlying functional recovery, there is only little evidence from clinical trials in the field of SCI. First, the study aims at monitoring StartReact effects in hand and leg muscles of patients with acute SCI over a period of 6 months. Simultaneous tracking of StartReact effects and motor recovery will allow to closely relate processes of reticulospinal plasticity to functional recovery in patients with acute SCI. Second, the focus will be on the re-weighting of descending motor control (i.e. cortico- vs. reticulospinal system) in response to SCI and investigate the distinct contributions of the cortico- and reticulospinal system to motor recovery in patients with chronic SCI. The findings of this project will advance the mechanistic understanding on the motor physiology and neurorestorative capacity of the reticulospinal system in humans. New insights from these projects will hopefully translate into a better exploitation of this important motor system in clinical trials that aim to improve motor recovery in patients with SCI.
Childhood and adolescence are crucial periods for prevention of obesity, as obese children are five times more likely to be obese at adulthood than lean children. To this purpose, sugar consumption should be reduced. The sugar alcohol erythritol is increasingly popular as sugar substitute in the food industry and is also recommended to diabetic patients. The substance is freely available. Recent acute studies show that erythritol has a positive influence on satiation and gastric emptying without affecting insulin and plasma glucose. In this trial, the investigators aim to assess the effect of a chronic intake of erythritol versus sucrose on insulin resistance in healthy adolescents. EryClot-Pilot: Erythritol is also produced by the human body and possibly elevated erythritol levels in the blood are an indication of an increased risk of cardiovascular disease, obesity or diabetes in the future. In a recently published study, a possible effect of erythritol on blood clotting function was described. In this in vitro experiment, increased blood clotting was observed when erythritol was added to clotting cells (platelets) in the test tube. Studies in humans on blood coagulation after administration of erythritol are missing so far. With a pilot study, the investigators study whether erythritol is detectable in the blood after administration of glucose and fructose. Furthermore, the erythritol level in the blood and a possible effect on the blood coagulation function after administration of erythritol will be investigated. These preliminary tests serve to clarify the data situation so that further studies can be based on them.

The purpose of this study is to evaluate safety of Deep Brain Stimulation (DBS) of the lateral hypothalamus (LH) and whether the use of DBS can increase motor performance in patients with chronic spinal cord injury (SCI). The hypothesis, based on preclinical findings, is that DBS of the lateral hypothalamus can acutely augment leg motor function after SCI, and that the use of lateral hypothalamus DBS can be an adjunct during rehabilitation to promote recovery and long-term neuroplasticity.
