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 purpose of this study is to evaluate if poor bone quality increases the risk of specific types of treatment complications in patients with proximal humerus fractures treated with open reduction and angle-stable plates (Proximal Humeral Internal Locking System - PHILOS).
The present study aims to compare the efficiency of respiratory therapy with cough assist and the efficiency of usual respiratory therapy in intensive care patients suffering of neurologic disorder and cough ineffectiveness. The investigators hypothesis is that cough assist is more efficient than usual respiratory care in this group of patients.
The prevalence of preterm birth is not decreasing in the last decades despite of improving health care. Intrauterine infections are important in the etiology of preterm birth but the interconnection of systemic inflammation and preterm birth is not clear. Mechanisms of preterm birth should be assessed as preterm birth is the major risk factor for morbidity and mortality during birth, thus being important for the individual and regarding health costs. No interventions will be carried out in this study. Hypotheses: 1. There is a common etiology between oral and vaginal inflammation 2. Bacterial species are similar in vagina and oral cavity 3. There are similar oral and systemic immune reactions which provoke preterm birth 4. Inflammatory markers are found in pregnant women at risk and get back to normal post partum In this matched case control study of pregnant women local, systemic and oral inflammation markers and bacterial load are assessed to find out interconnections between these body compartments to allow for explanation of the etiology of preterm birth.
The designed study follows up the retrospective previous one by the International T-cell Non-Hodgkin's Lymphoma Study Group (International Peripheral T-Cell Lymphoma Project). It is designed as a prospective collection of information potentially useful to predict the prognosis of newly diagnosed patients with the more frequent subtypes of Peripheral T-cell lymphoma (Peripheral T-cell lymphoma unspecified and Angioimmunoblastic T-cell lymphoma) and to better define clinical characteristics and outcome of the more uncommon subtypes
This research trial studies a risk-based classification system for patients with newly diagnosed acute lymphoblastic leukemia. Gathering health information about patients with acute lymphoblastic leukemia may help doctors learn more about the disease and plan the best treatment.
Selenoenzymes play a major role in protecting cells against lipid peroxidation and they are involved in the inflammatory response regulation. The degree of selenium deficiency correlates with disease severity and the incidence of mortality in critically ill patients. The aim of our study is to evaluate, if high dosis selenium supplementation (loading dose 4000 μg, daily dosage 1000 μg) results in a significant reduction of inflammation-induced organ dysfunction and length of ICU-stay in patients after heart surgery.
Methylmalonic acidemia (MMA) is a rare genetic disorder caused by mutations in the gene for mitochondrial enzyme methylmalonyl-CoA mutase (MCM) or in one of the genes for adenosylcobalamin (AdoCbl). Lack of these proteins causes toxic elevations of methylmalonic acid (MMacid) in blood, urine, and other tissues. A specific type of mutation, called a nonsense (premature stop codon) mutation, is the cause of the disease in approximately 5% to 20% of participants with mutations in the MCM gene, and approximately 20% to >50% of participants with mutations in one of the AdoCbl genes. Ataluren is an orally delivered, investigational drug that acts to overcome the effects of the premature stop codon, potentially enabling the production of functional MCM/AdoCbl. This study is a Phase 2a trial evaluating the safety and activity of ataluren in participants with MMA due to a nonsense mutation. The main purpose of this study is to understand whether ataluren can safely decrease MMacid levels.
Primary Objective: - Evaluate the rate of Atrial Fibrillation (AF) recurrences one month after randomization according to different timings of initiation of dronedarone. Secondary Objective: - Evaluate the rate of AF recurrences two months after randomization. - Assess the safety of the change from amiodarone to dronedarone - Assess dronedarone safety - Explore dronedarone and its active metabolite plasma level (in a subset of countries) - Explore potential Pharmacokinetic (PK) interaction between dronedarone and amiodarone (in a subset of countries)
This is a Phase 3 multicenter, randomized study evaluating the safety and efficacy of ramucirumab DP plus BSC as a double-blind, placebo-controlled (placebo plus BSC) comparison. Approximately 544 participants, at least 18 years of age, with Child-Pugh score < 7 and diagnosed with hepatocellular carcinoma will be randomized. Participants must have received sorafenib as first-line systemic treatment for hepatocellular carcinoma (HCC), and must have discontinued sorafenib prior to entering the study. Hypothesis: This sample size will allow differentiation of the expected increase in median overall survival (OS), from 8 months in the placebo arm to 10.67 months in the ramucirumab arm. Upon registration and completion of screening procedures, eligible participants with HCC who have disease progression during or following first-line therapy with sorafenib, or were intolerant to this agent, will be randomized to receive either ramucirumab DP or placebo. The treatment regimen will be continued until radiographic or symptomatic progression, the development of unacceptable toxicity, noncompliance or withdrawal of consent by the participant, or investigator decision.
The purpose of this study is to determinate the effect of a pre-treatment with centrally acting alpha2-receptor agonist clonidine on the pharmacodynamics and pharmacokinetics of 3,4-methylenedioxymethamphetamine (MDMA, "Ecstasy"). The investigators hypothesize that clonidine will attenuate the subjective and cardiovascular response to MDMA.
