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.
A functioning vascular access provides a lifeline for patients requiring haemodialysis but vascular access dysfunction remains one of the leading causes of excessive morbidity, mortality and healthcare costs in this group. Despite increasing numbers of vascular access trials, successful interventions to improve vascular access function have been sparse and compromised by highly variable, often selectively reported outcome measures of limited relevance to patients and health professionals. Through engagement of all relevant stakeholders including patients and caregivers, vascular access function, defined by the need for interventions to enable and maintain the use of a vascular access for haemodialysis, has been identified as one of the most critically important outcome measures for trials in haemodialysis. This prospective, multi-centre, multinational validation study aims to assess the accuracy and feasibility of measuring vascular access function part of routine clinical practice and across different clinical settings to ensure successful global implementation of this core outcome measure in future trials in haemodialysis.
Patients suffering of Parkinson's Disease will be treated with 50 mg/day of Safinamide per os for 2 weeks (escalation phase). Then, safinamide will be increased up to 100 mg/day and, if tolerated, the treatment will be taken for 10 more weeks (maintenance phase). Total treatment 12 weeks.
Multinational, investigator-initiated study of oral anticoagulation versus no anticoagulation for the prevention of stroke and other adverse cardiovascular events in patients with transient perioperative atrial fibrillation after noncardiac surgery and additional stroke risk factors.
This study will compare meniscal healing of non-vascularised area augmented or not by bone marrow injected under a protective collagen membrane (meniscal wrapping)
The use of corticotomy surgery in addition to orthodontic standard treatment could accelerate the treatment. Corticotomy involves vertical interdental incisions of the gingiva and the bone with a very low thickness. Orthodontic appliances are placed immediately after the surgery. This study aims to compare the tooth movement when correcting mandibular dental crowding in two groups of patients: Test group: orthodontic treatment and minimally invasive corticotomy surgery. Control group: standard orthodontic treatment without surgery.
Prospective, observational, single-centre, non-interventional study aiming at reporting the prevalence of ATTRwt in patients with lumbar spinal stenosis (LSS).
A multicentre single arm phase II trial assessing the efficacy of immunotherapy, chemotherapy plus stereotactic radiotherapy to metastases followed by definitive surgery or radiotherapy to the locoregional primary tumour, in patients with histologically-confirmed synchronous oligo-metastatic non-small cell lung cancer (NSCLC).
Most patients with spinal cord injury (SCI) develop neurogenic lower urinary tract dysfunction (NLUTD), one of the most devastating sequelae of SCI which ultimately can lead to renal failure. We urgently need an intervention that prevents NLUTD before irreversible damage occurs. Neuromodulation procedures are a promising avenue so that we investigate the effect of transcutaneous tibial nerve stimulation (TTNS) in patients with acute SCI. This nationwide randomized, sham-controlled, double-blind multicentre clinical trial includes all SCI centres in Switzerland (Basel, Nottwil, Sion, Zürich). Patients are randomly assigned to VERUM TTNS (active stimulation, n=57) and SHAM stimulation (n=57) groups in a 1:1 allocation using computer-generated permuted block randomisation lists stratified on study centre and lower extremity motor score. Daily 30-minute sessions are performed five times a week during an intervention period of 6-9 weeks. The primary outcome of this study is the success of TTNS to prevent neurogenic DO jeopardizing the upper urinary tract, assessed by urodynamics at 1 year after SCI or any earlier time point if DO treatment is necessary (study end). Secondary outcome measures are bladder diary parameters, clinical symptom scores assessed by standardized and validated questionnaires. Furthermore, neurophysiological and neuroimaging outcome measures are assessed as well as, biochemical and molecular changes. Tertiary outcome measure is the safety of TTNS. Before the actual start of the TASCI RCT, start-up activities will include a piloting phase on groups of healthy volunteers and patients. The goal during this phase is to evaluate the feasibility of the experimental setup, in particular for the TTNS and SHAM intervention, but also to test the setup of the different pre and post assessments (e.g. neurophysiology and neuroimaging tests). Groups of up to 15 participants each will be enrolled in a few consecutive pilot studies allowing for fine tuning and small adaptations in between, if appropriate.
This study is performed to evaluate the outcome of conservative treatment after distal radius fractures in patients of 65 years or older at the time of the injury, primarily with respect to the prognostic value of the Adolfsson-score for the functional demands of the patient on his hand.
Surgical site infections in orthopaedic surgery are a major problem. Decolonization has been suggested to reduce infection rates. The study was designed as a prospective, controlled, randomized, single-blinded trial to assess the influence of a decolonization procedure in S. aureus and non - S. aureus carriers. In this trial the 2 - year outcome in the subpopulation of prosthetic elective orthopaedic surgery will be evaluated.
