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.
This clinical investigation is designed to describe the long-term safety and efficacy of the CVRx Rheos Baroreflex Hypertension Therapy System in patients who participated in the DEBuT-HT study beyond the original follow up period (4-months or longer). The information obtained in this trial is intended to support regulatory approvals and market release of this therapy.
The purpose of this study is to demonstrate the safety and efficacy of the Rheos Baroreflex Hypertension Therapy System in patients with refractory hypertension.
Treatment of chronic pelvic pain syndrome (CPPS) is challenging for patients and physicians once conventional therapies fail. We hypothesize that combined sono-electro-magnetic therapy can improve refractory CPPS in men.
This study involves the use of Magnetic Resonance Imaging (MRI) contrast agents called gadobutrol (Gadavist) Injection and ProHance Injection. The purpose of this study is to look at the safety (what are the side effects) and efficacy (how well does it work) of gadobutrol when used for taking MR images of the brain and spine. The results of the MRI with gadobutrol Injection will be compared to the results of MR images taken without contrast and with the results of the MR images taken with ProHance.
The purpose of this study is to compare the safety, tolerability and efficacy of a regimen containing once-daily elvitegravir (EVG) versus twice-daily raltegravir added to a background regimen (containing a fully-active ritonavir-boosted protease inhibitor [PI/r] and a second agent) in HIV-1 infected, antiretroviral treatment-experienced adults who have documented resistance, or at least six months experience prior to screening with two or more different classes of antiretroviral agents. Participants will be randomized in a 1:1 ratio to receive EVG plus background regimen (elvitegravir arm), or raltegravir plus background regimen (raltegravir arm).
This study will assess the safety and immunogenicity of a GSK Biologicals' candidate TB vaccine (692342) administered at 0, 1 month to HIV-positive adults living in Switzerland.
The aim of the study is to show non-inferiority of an echinacea/sage spray compared to a chlorhexidine/lidocaine-spray in the treatment of acute sore throat during five days of treatment. Main outcome parameter is the non-inferiority in number of responders between the two treatment groups. A responder is defined as a reduction by 50% of the total baseline score taken prior to treatment start. The symptoms are assessed with a symptom score.
Until recently, the tuberculin skin test (TST) was the only available diagnostic assay for detection of latent infection with M. tuberculosis (LTBI). Despite the low overall incidence of symptomatic tuberculosis infection in low-prevalence countries, the potential mortality and morbidity mandate constant vigilance to identify patients at risk for reactivation. Due to systemic immunosuppression, immunocompromised patients with latent M. tuberculosis infection are at increased risk of progression to active disease. This applies to patients with various causes of immunodeficiency such as HIV-infected patients, allogeneic stem cell and solid organ transplant recipients, patients with rheumatoid arthritis and patients with chronic renal failure. Therefore, current guidelines aimed at preventing tuberculosis infection in immunocompromized individuals recommend a generalized screening for evidence of latent infection to target appropriate preventative prophylaxis. At present, tuberculosis control programs exclusively rely on the tuberculin skin test to identify a latent infection in asymptomatic individuals. Recently, novel in vitro assays termed T cell interferon-gamma release assay (TIGRA) have become available that are based on the detection of interferon-gamma (IFN-gamma) production in T cells or supernatants after stimulation with highly specific antigens of M. tuberculosis. Two TIGRA are commercially available, the ELISPOT based T.SPOT.TB and the ELISA based QuantiFERON-TB Gold test (now available as an "IN-TUBE" version). The aim of the study is a prospective comparison of the two commercially available approved TIGRA (QuantiFERON-TB Gold In-Tube and T.SPOT.TB) with the established Mendel-Mantoux skin-test in immunocompromized patients (main focus on sensitivity and specificity). The study hypotheses are as follows: 1. In immunocompromised patients, the two commercially available approved TIGRA (QuantiFERON-TB Gold In-Tube and T.SPOT.TB) have increased sensitivity and specificity as compared to the established Mendel-Mantoux skin-test. 2. Results from QuantiFERON-TB Gold In-Tube and T.SPOT.TB do not differ in immunocompromised patients.
Study Design: Single-centre, block randomised, blinded, controlled, phase IIIb, parallel group pilot study. Primary Objective: • To evaluate the effect of the administration of ferric carboxymaltose (Ferinject®) with or without erythropoietin vs. no treatment (standard therapy) on the preoperative anaemia status in patients undergoing orthopaedic surgery Secondary Objective: - To gain informations for the design of a possible follow-up study - To evaluate the effect of the administration of ferric carboxymaltose (Ferinject®) with or without erythropoietin vs. no treatment (standard therapy) on pre- and postoperative Hb levels, iron status, transfusion rate, days until discharge. - To evaluate the tolerability and safety of Ferinject® Study Centres: This is a single centre study Patients: A total of 75 completed patients (50 patients in the intravenous iron treatment groups and 25 patients in the no treatment group will be recruited.
Background: COPD is a systemic illness; morbidity and mortality due to this disease are on the increase, and it has great impact on patients' lives. Most COPD patients are managed by general practitioners (GP). GPs base their initial assessment of patients' disease severity mainly on lung function and then inform patients about adequate treatment. However, lung function correlates poorly with COPD-specific health-related quality of life and exacerbation frequency. Preventive cardiology embraced risk index-guided treatment successfully. COPD disease severity indices that better represent the clinical manifestations of COPD are needed that can be used to guide risk-stratified treatment. Objectives: (1) The development and validation of a practical COPD disease severity index to predict the course of health-related quality of life over time. (2) The validation of the ADO-Index (Age, Dyspnea, Obstruction) to predict 3-year mortality in COPD patients in primary care. (3) Link evidence on treatment effects to the COPD risk indices to guide COPD treatment selection. Methods: We are in the process of conducting two linked prospective cohort studies with 413 COPD patients (GOLD stages 2-4) from GPs in Switzerland and the Netherlands. We performed a sound baseline assessment including detailed patient history, lung function, measurement of exercise capacity and blood sampling. During the follow-up of at least five years, we update the patients' profile by registering health status, exacerbations and health-related quality of life and, after 2 years, lung function and measurement of exercise capacity. For aim 1, we will identify the best combination of variables predicting the course of health-related quality of life over time using multivariable regression analysis. For aim 2, we will assess discrimination and calibration of the ADO index to predict 3-year mortality. For aim 3, we will estimate treatment effects for individual patient profiles using complex statistical models such as Markov models. Significance of project: After this study, different risk scores will be available for use in primary care so that general practitioners can estimate what impact COPD will have on the patients. By linking these risk scores to evidence form treatment studies, it will be possible to show for an individual patient how COPD and different treatments impacts on mortality, symptoms and exacerbations. Thereby, patients and physicians can make more informed treatment decisions balancing the benefits and downsides of different treatments.
