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 investigate the clinical, cognitive outcome and psychosocial outcome of haemolytic uraemic syndrome in childhood. The haemolytic uraemic syndrome (HUS) is the leading cause of acute renal failure in childhood. The more common typical HUS is mostly caused by Shigatoxin-producing enterohaemorrhagic Escherichia coli (EHEC). The rarer atypical HUS is mainly caused by different genetic abnormalities in complement regulatory proteins. About 50 till 60 percent of all patients with HUS develop a severe acute renal failure and require dialysis. Resulting from new diagnostic and therapeutic approaches the survival rate increased during the last years. Despite this, there are only few data concerning long-term prognosis, cognitive and motoric development, as well as psychological coping and health-related quality of life of affected children and their parents.
Primary cutaneous squamous cell carcinomas (SCCs) are epithelial carcinomas with a high frequency of EGF-R expression. EGFR is an important regulator of tumour progression and proliferation in several types of cancer. Mechanism of action of Lapatinib in the EGFR and/or HER2 expressing oesophageal squamous cell carcinoma (ESCC) cells is attributed to inhibition of cell proliferation and induction of apoptosis. Based on the data from oesophageal SCCs the investigators hypothesise that EGFR signalling pathway and its interactions play an important role in the SCC pathogenesis and represent a good therapeutic target from these tumours. Primary Objectives: To evaluate the tumour response macroscopically in patients with primary cutaneous SCC lesions and in concomitant SCC in situ (AK). Secondary Objectives: - To evaluate tolerability of a single dose regimen of systemic lapatinib therapy in patients with SCC as measured by time to first AE or SAE within the study period. - To investigate the molecular tumour response of squamous cell carcinoma lesions in patients under lapatinib treatment using a set of variables. - Trial with medicinal product
This is an open, monocentric, pilot study to determine the metabolic activity (glucose-uptake) in vivo during monotherapy with pazopanib in comparison to combination therapy with pazopanib plus paclitaxel and to investigate the transcriptional profile of cutaneous melanoma metastasis before and during the therapy (pazopanib vs. pazopanib plus paclitaxel) in subjects with unresectable Stage III or Stage IV melanoma who have not received prior cytotoxic chemotherapy. Primary Objective: Evaluation of metabolic activity in vivo Secondary Objective: Determination of changes in gene expression profiling Evaluation of the antitumor activity of the combination in terms of progression free survival (PFS). Changes in S100 and LDH during therapy at the same time points as FDG-PET/CT (a combined serum measurement of S100 and LDH) - Trial with medicinal product
Background: In a simulation based on a pharmacokinetic model we demonstrated that increasing the erythropoiesis stimulating agents (ESAs) half-life or shortening their administration interval decreases hemoglobin variability. The benefit of reducing the administration interval was however lessened by the variability induced by more frequent dosage adjustments. The purpose of this study was to analyze the reticulocyte and hemoglobin kinetics under different ESAs and administration intervals in a collective of chronic hemodialysis patients. Methods: The study was designed as an open-label, randomized, four-period cross-over investigation, including 30 patients under chronic hemodialysis at the regional hospital of Locarno (Switzerland) in September 2009 and lasting 2 years. Four treatment strategies (C.E.R.A. every 4 weeks Q4W and every 2 weeks Q2W, Darbepoetin alfa Q4W and Q2W) were compared with each other. The mean square successive difference of hemoglobin, reticulocyte count and ESAs dose was used to quantify variability. We distinguished a short- and a long-term variability based respectively on the weekly and monthly successive difference.
Intramyocardial, NOGA guided injection of bone marrow derived mononuclear cells in patients with chronic ischemic heart disease and LVEF < 40%. The primary objective is to determine whether the administration of the cells improves recovery of the left ventricular function. Secondary objective is the finding of clinical or paraclinical parameters to predict potential benefits of the treatment (basing on MRI characteristics such as size, transmurality of the myocardial infarction and peri-lesional ischemia). In the first part of the study 10 patients are treated without control group. This phase serves as feasibility and safety part of the study.
Background: Lower limb arterial revascularization procedures, either percutaneously or surgically performed, are an established treatment modality of ischemic foot ulcers, especially in the setting of a critical limb ischemia. Many other lower limb ulcers are secondary to a combined disease, which may include a concomitant venous disease (chronic venous insufficiency or varicous disease) or a micro-angiopathic disease (i.e. small vessel disease). In this setting, and especially in the absence of a concomitant severe macro-angiopathic disease, the safety and efficacy of a percutaneous lower limb revascularization have so far never been evaluated in a prospective study. Aim: This study is aimed to evaluate the safety and the efficacy of an endovascular revascularization approach of the lower limb, in all consecutive patients presenting with a non-healing ulcer associated with a mild to moderate peripheral artery disease (i.e. mixed-origin ulcers). Material and methods: This prospective study will consecutively include all patients presenting with a non-healing ulcer. Included patients must have all the concomitant ulcer co-factors being adequately treated for at least 6 months. Accordingly, an underlying venous disease, infectious disease or inflammatory disorder must be previously evaluated and adequately treated (i.e. compression stocking, varices stripping, antibiotics, local ± systemic anti-inflammatory, etc.). Furthermore, a non-invasive arterial evaluation must be obtained in all patients. The arterial screening must included an ankle-brachial index (ABI) and toe pressure (TP) measurements, a trans-cutaneous oxygen measurement (tcPO2) at the foot and calf levels and a non-invasive arterial mapping (i.e. angio-CT or angio-MRI). This arterial work-up must be compatible with the presence of a mild to moderate peripheral artery disease without any sign or criteria suggesting the presence of a critical limb ischemia. End-points: The success rate of perform an endovascular revascularization intervention in all consecutive patients which qualify according to the inclusion criteria (technical feasibility). Establish the proportion of procedural related complications (safety). Analyze the clinical and the para-clinical improvements in term of heal of the ulcers, as well as the improvement of the ABI, TP, tcPO2 at 1 week, 1-3-6 months after the procedure (efficacy). Sample size: The investigators plan to include ≈ 30 patients in two years. After 1 year of enrollment the investigators will perform an interim analysis and will decide at that moment, according to the observed end-points, if prolonging the study would be of any scientific value or if the study has to be interrupt earlier because of a significant improvement of all already treated ulcers.
Evaluate the safety and efficacy of Siponimod (BAF312) versus placebo in a variable treatment duration in patients with secondary progressive multiple sclerosis (Core Part) followed by extended treatment with open-label BAF312 to obtain data on long-term safety, tolerability and efficacy (Extension Part).
The purpose of this study is to evaluate the efficacy and safety of belimumab, in combination with azathioprine, for the maintenance of remission following a standard induction regimen in patients with Wegener's granulomatosis or microscopic polyangiitis. The random assignment in this study is "1 to 1" which means that participants have an equal chance of receiving belimumab or placebo.
Primary Objective: To compare the effect of alirocumab with placebo on the occurrence of cardiovascular (CV) events (composite endpoint of coronary heart disease (CHD) death, non-fatal myocardial infarction (MI), fatal and non-fatal ischemic stroke, unstable angina (UA) requiring hospitalization) in participants who experienced an acute coronary syndrome (ACS) event 4 to 52 weeks prior to randomization and were treated with evidence-based medical and dietary management of dyslipidemia. Secondary Objectives: - To evaluate the effect of alirocumab on secondary endpoints (any CHD event , major CHD event, any CV event, composite of all cause mortality/non-fatal MI/non-fatal ischemic stroke, CHD deaths, CV deaths, all cause mortality). - To evaluate the safety and tolerability of alirocumab. - To evaluate the effect of alirocumab on lipid parameters.
