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.
Compare safety of Lacosamide (LCM) to Carbamazepine Controlled-Release (CBZ-CR) as monotherapy in newly or recently newly diagnosed subjects with primary safety variables including spontaneous reports of Adverse Events (AEs), withdrawal of subjects due to AEs, reporting of Serious AEs (SAEs).
This study compares the interactive emotional/subjective effects of single doses of 3,4-methylenedioxymethamphetamine (MDMA, "ecstasy") and methylphenidate, a dopamine (DA) and norepinephrine (NE) transporter blocker, in healthy subjects. The primary goal is to determine the role of transporter mediated DA and NE release in the subjective response to MDMA in humans. The investigators hypothesize that methylphenidate will attenuate the subjective response to MDMA.
Water imbalance and consecutive electrolyte disturbances are common in the postoperative course of neurosurgical patients after pituitary surgery. Diabetes insipidus (DI) may complicate the postoperative course in as many as 30% of patients. Early and accurate diagnosis of water and electrolyte disturbances postoperatively is important for an adequate fluid and drug administration. However, identifying the causes is challenging/ ambiguous in clinical practice. Levels of antidiuretic hormone (ADH) might contribute to a straightforward diagnosis, though, its measurement is cumbersome. ADH is derived from a larger precursor peptide along with copeptin, which is a more stable peptide directly mirroring the production of ADH. Copeptin can be assayed readily in plasma. Aim: To investigate whether copeptin can accurately diagnose postoperative disturbances of water homeostasis (i.e. Diabetes insipidus and SIADH) in a cohort of patients undergoing intracranial tumor surgery.
Exercise intolerance is a major burden for patients with complex congenital heart disease (CHD), significantly affecting their quality of life. Cardiopulmonary exercise testing provides a reliable tool both for assessing exercise capacity of CHD patients and for risk stratification and is becoming part of the routine clinical assessment of these patients. Exercise has an effect on the muscular, metabolic and circulatory systems. While exercise training has been widely studied in chronic heart failure, its efficacy in adults with CHD remain unknown. The investigators hypothesize that structured exercise training will improve exercise intolerance, in particular peak VO2. The aim of this multicenter, randomized study is to evaluate the impact of structured exercise training on exercise intolerance in patients with complex CHD.
Acanthocytes, also termed spur cell, are large erythrocytes covered with spike-like projections which are associated with severe hemolytic anemia. In advanced cirrhosis, acanthocytes may account for 20 to 30% of red blood cells. Up to 70% of cirrhotic patients display anemia and hemoglobin level may fall to below 5 gr/L in spur cell anemia. The true incidence of spur cells in cirrhosis is not known precisely but may avoisinate 45%, typically in patients with advanced cirrhosis.The presence of spur cells usually predicts lower survival rates. Vitamin E is an antioxidant compound that is a component of biological membrane that helps to maintain integrity of lipid bilayers. Vitamin E deficiency leads to erythrocyte hemolysis, which is improved by supplemental vitamin E. This study is an open label single arm phase II study in cirrhotic patients treated for 4 weeks with Tocofersolan (Vedrop), a water-soluble derivative of alpha-tocopherol, and thus an orally bio-available source of vitamin E. The aim of this study is to determine the effect of tocofersolan on red blood cell membranes lipid composition in adult patients with cirrhosis and vitamin E deficiency. Secondary endpoints are the effects of tocofersolan on anemia, hemolysis and acanthocytosis; on lipid peroxidation and oxidative stress; the safety of a 4 week treatment of 700 mg/day.
To study the effect of acute pulmonary vasodilatation on cerebral tissue oxygenation (CTO) and cerebral blood flow (CBF) as indicator for cerebrovascular autoregulation in comparison to the effects of supplemental oxygen, decreased carbon dioxide by hyperventilation and exercise in patients with pulmonary hypertension (PH) undergoing clinically indicated right heart catheterisation (RHC). Oxygenation and hemodynamic parameters will be assessed during RHC according to standard procedures. Non-invasive near infrared spectroscopy (NIRS) and a nasal canula will be additionally applied to measure CTO, CBF and endtidal CO2 (EtCO2). All parameters will be obtained at rest breathing room air, during an oxygen challenge, during standardized hyperventilation, under vasodilatation testing and during exercise in random, single-blinded sequences (except for exercise and hyperventilation). Pulmonary, systemic and cerebral oxygenation parameters and hemodynamics will be correlated with each other and functional class, quality of life, exercise and cognitive assessments at the time of the RHC and after three month.
This multicenter, randomized, open-label, parallel-group study will evaluate the efficacy and safety of subcutaneously administered rituximab in comparison with observation only as maintenance therapy in participants with relapsed or refractory indolent Non-Hodgkin's lymphoma (NHL). All participants will receive induction therapy with rituximab (375 milligrams per square meter [mg/m^2] intravenously [IV] in Cycle 1, then 1400 mg subcutaneous [SC] every 3-4 weeks) plus standard chemotherapy for 6-8 months; followed by 24 months of maintenance I period with rituximab (1400 mg SC every 8 weeks). Participants completing therapy and showing partial or complete response will be randomized to receive either rituximab (1400 mg SC every 8 weeks) or observation with no treatment during maintenance II period and will be followed for at least 15 months. Anticipated time on study treatment is until disease progression, unacceptable toxicity or end of study, whichever occurs first.
This investigation is designed to demonstrate the clinical safety of the EVIA/ ENTOVIS pacemaker system when used under specific MRI conditions.
Retrospective correlation of clinical outcomes data with mutational status in GIST subjects treated with sunitinib.
This international, prospective, observational, open-label, pharmaco-epidemiologic study observes cancer patients at risk for chemotherapy-induced febrile neutropenia (FN) who are receiving filgrastim biosimilar (EP2006) for primary or secondary FN prophylaxis to better describe the patient population at risk for FN and treated prophylactically in physician's best clinical judgement with filgrastim biosimilar (EP2006), to describe prophylaxis patterns involving filgrastim biosimilar (EP2006), and to evaluate hematology levels and variability in hematological outcomes, impact on chemotherapy delivery, radiotherapy, surgery, and mortality. Additionally the study aims to identify patient cohorts who are vulnerable to poor response to FN prophylaxis and experience break-through episodes of FN, understand the differences between prophylaxis responders and non-responders, and describe the degree to which prophylaxis of FN is in congruence with guideline recommendations.
