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 aim of the registry is to collect laypeople's performance after a BLS/AED course carried out with the use of feedback devices.
This study investigates the effects of a 12-week high-intensity interval training (HIT) on exercise tolerance, functional status and quality of life in patients with chronic heart failure with preserved ejection fraction (HFpEF), in comparison to a control group undergoing a 12-week moderate-intensity continuous training.
This is prospective, non-randomized, single-arm, international, multicenter, clinical safety and performance clinical investigation to evaluate the AccuCinch® Ventricular Repair System for the treatment of heart failure, with or without functional mitral regurgitation due to dilated ischemic or non-ischemic cardiomyopathy
This is a two-phase multicenter, double-blind, randomized, prospective evaluation of intra-articular injection(s) comparing APS to intra-articular HA injection(s). The maximum study duration for each subject will be 62 months; 60 months from treatment to last follow-up, and two additional months if the maximum visit window is realized. A total of 246 patients will be enrolled. These patients will meet specific inclusion and exclusion criteria, but can be generally characterized as patients with painful unilateral knee OA who have been unable to achieve satisfactory pain relief with previous conservative OA treatment.
Patients will be randomized (1:1 ratio) to receive either 4 weeks of Ondansetron followed by 4 weeks of placebo (O-P sequence) or 4 weeks of placebo followed by 4 weeks of Ondansetron (P-O sequence). It will be one week of washout between the two treatments. During the treatment questionnaires will be completed by the patients to evaluate the efficacy of the study treatment and the quality of live.
Numerous psychiatric and neurodegenerative diseases like schizophrenia, dependency on drugs of abuse, depression and Parkinson's disease are related to motivational and cognitive deficits in value-based decision making, which frequently persist even after a successful pharmacological treatment. According to current neurobiologic models, cortical dopamine D1 receptors play a crucial role in taking value-based decisions. In this study, it will be investigated whether value-based decisions in healthy volunteers can be improved by stimulation of D1-receptors. For this purpose, a newly developed dopamine D1-agonist will be used, which selectively increases the activities of frontal D1- and D5-receptors. In this double-blind, randomized, placebo-controlled study, the effects of different single doses of PF-06412562, a not yet licensed D1-agonist, on value-based decision making will be compared with placebo. The use of different dosage strengths will allow to investigate a potential relationship between the extent of activity of the D1-receptor and its influence on behavioral indices. Therefore, four parallel groups will be investigated. Each participant takes in a single dose of either PF-06412562 in different doses or placebo. A screening exam will be carried out 1-3 weeks before the drug intake, and a follow-up examination will be carried out approx. 1 week after the drug intake. At all 3 visits in the study centre, several tests for the investigation of value-based decision making will be carried out.
Stroke is a leading causes of death and disability. At least 20% of strokes occur during sleep, so- called 'wake up stroke'. Thrombolysis with the clot-busting drug alteplase is effective for acute ischaemic stroke, provided that it is given within 4.5 hours of symptom onset. Patients with wake-up stroke are currently ineligible for clot-busting therapy. Previous studies indicate that many wake-up strokes occur just before awakening. In this study, patients with wake-up stroke will be randomized to thrombolysis with tenecteplase and best standard treatment or to best standard treatment without thrombolysis. Tenecteplase has several potential advantages over alteplase, including very rapid action and that it can be given as a single injection. Prior to thrombolysis, a brain scan must be done to exclude bleeding or significant brain damage as a result from the stroke. We will use a CT scan to inform this decision. CT is used as a routine examination in all stroke patients. Other studies testing clot-busting treatment in wake-up stroke are using alteplase and more complex brain scans, which are not routinely available in the emergency situation in all hospitals.
Bioresorbable vascular scaffold (BVS, ABSORB BVS1.1, Abbott Vascular) has been approved (CE mark) and is used in daily clinical practice. While recent randomized controlled trials comparing BVS versus metallic drug-eluting stent showed higher risk of definite or probable device thrombosis after BVS implantation, the causes underlying thrombotic events occurring beyond one year after scaffold implantation remain unclear and require investigation in an independent manner. The INVEST registry is a world-wide, multi-center, observational, retrospective, investigator-initiated registry, which will include any patients who suffered from very late (>1 year) scaffold thrombosis, underwent optical coherence tomography (OCT) at the time of thrombosis and provided informed consent for the further use of their health related data for this registry.
Background: Due to the remarkable improvement in treatments these last decades, long term survival can be expected in more than 80% of childhood cancer patients. Unfortunately, cancer treatments can be harmful to the gonads and can affect reproductive and endocrine functions. While loss of fertility is a major concern for most patients, sperm cryopreservation should be offered to all pubertal male patients. For prepubertal boys, only the experimental option of testicular biopsy in order to cryopreserve testicular stem cells can be proposed. Primary aims - To cryopreserve testicular tissue of prepubertal patient receiving highly gonadotoxic oncological treatment. Secondary aims - To cryopreserve testicular tissue after failure of sperm cryopreservation in pubertal patient with high risk of infertility - To create a database in order to record clinical and biological follow-up data - To create a research biobank for future research projects Multicentric study: HUG, CHUV, UKBB
Background: Due to the remarkable improvement in treatments these last decades, long term survival can be expected in more than 80% of childhood cancer patients. Unfortunately, cancer treatments can be harmful to the gonads and can affect reproductive and endocrine functions. While loss of fertility is a major concern for most patients, only the experimental option of ovarian tissue cryopreservation can be proposed to prepubertal girls with a high risk of infertility. For pubertal patient, cryopreservation of mature oocytes after ovarian stimulation can be offered if oncological treatment debut can be delayed. As it is often not possible, ovarian tissue cryopreservation can also be offered. Primary aims - To cryopreserve ovarian tissue of pre or peripubertal patient who will be receiving highly gonadotoxic oncological treatment. Secondary aims - To create a database in order to record clinical and biological follow-up data - To pool resources with Fertisave Registry - To create a research biobank for future research projects Multicentric study: HUG, CHUV
