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 study aims for an in-depth characterization of human milk of mothers who delivered prematurely to decipher differences with milk of mothers who delivered at the expected term, with a particular focus on milk proteins
The purpose of this study is to evaluate the accuracy of shoulder replacement surgery in realization a computer assisted 3D planning compared to conventional 2D planning.
To investigate whether copeptin levels increase upon a psychological stress (i.e. written examination) and whether copeptin levels measured immediately before the written examination predict success of the examination.
Part 1 is a multicenter, randomized, double-blind, placebo-controlled, parallel-group study will evaluate the efficacy and safety of gantenerumab in participants with mild Alzheimer disease. Participants will be randomized to receive either gantenerumab subcutaneously every 4 weeks or placebo subcutaneously every 4 weeks. Approved Alzheimer medication is allowed if on stable dose for 3 months prior to screening. Part 2 is an open-label extension (OLE). A positron emission tomography (PET) imaging substudy will be conducted within the main study. Eligible participants who provide separate informed consent will undergo PET imaging scans using the radioligand florbetapir as a pharmacodynamic measure of changes in brain amyloid load over time.
The aim of the trial is to test the hypothesis that the benefit of denosumab is maintained if administered only every 12 weeks as compared to every 4 weeks.
Background: Oral iron supplementation (OIS) is a widely-used strategy to treat iron deficiency anemia. However, absorption of OIS is often low and response is variable. To overcome this, large doses are given but this may reduce compliance due to gastric irritation. Thus, OIS doses should be low, while maximizing absorption. The prevailing serum hepcidin concentration (SHep) is the major determinant of iron absorption and erythrocyte iron utilization. Based on limited data in humans, SHep can be increased by a single OIS dose but the duration of the increase is uncertain: In a recent study conducted in our laboratory it has been found to last approx. 24 h. Also, there are few data on how the increase in SHep determines the absorption of further doses of oral iron. Is there a threshold SHep at which subsequent iron absorption is sharply reduced? Better understanding of this relationship would be valuable to design more effective and safer OIS regimens. Objectives: 1) Determine whether two consecutive dosages of 60 mg Fe differently affect hepcidin response and iron bioavailability (Study 1) 2) Compare the bioavailability of iron supplement dosages given at different times of the day (Study 2). Methods/Subjects: Healthy female subjects will be screened for low iron status. Anemic subjects will be excluded from the study. Thirty two subjects will be included with serum ferritin <20 µg/L, C-reactive protein <5 mg/L and Hemoglobin >117 g/L. Subjects will be randomized in two groups and their Hepcidin (sHep) and iron status markers monitored at day 1 (baseline). Subjects will receive iron supplement dosages of 60 mg with stable iron isotopes 54Fe, 57Fe, 58Fe in form of 4 mg of FeSO4. Prior administration blood samples will be collected to monitor sHep and iron status markers. Outcome: The combined use of stable iron isotopes and a sensitive SHep assay will allow for better understanding of the iron-hepcidin relationship and this may enable design of more effective OIS regimens.
Title ThoHSpEkt Study Design Pilot Study concerning the technical operative methods and a phase II study concerning the radiopharmaceutical (therapeutic-explorative study with an approved drug in a new indication) Location Kantonsspital St.Gallen Aim Proof of feasibility of thoracoscopic ectomy of radioactively marked pulmonary nodules with the help of free-hand SPECT. Background In the Cantonal Hospital of St.Gallen an average of 30 - 40 patients will be operated with thoracoscopic ectomy for a pulmonary nodule. When localisation of the nodule is not possible a switch to minithoracotomy is performed. Study intervention Marking of pulmonary nodules with radioactivity. Free-hand SPECT guided surgery Risks Risks of bronchoscopic or CT-intervention Radiation risk (minimal) Rational for patient number 10 patients for each group are enough to prove the feasibility, to manage difficulties and to record complications Duration approximately 24 months.
Clinical trial in patients with obstructive sleep apnoea that are randomised to either continue or withdraw continuous positive airway pressure therapy to identify a disease-specific exhaled breath pattern by mass spectrometry.
Measurement of skin reactivity of cat dander samples obtained by different methods. Subjects will be assessed for the study by of a conventional skin prick test with a positive (histamine), a positive (standardized cat dander extract) and a negative allergen control (a diluent) if they fulfil all other in- and exclusion criteria, too. A screening prick test will be performed in order to confirm positivity (cat dander allergy). A scratch test will be performed in participants after a positive screening prick test, in order to measure skin reactivity to cat dander, originating of three different body areas of the cat. For this purpose, a small amount of cat fur in solution with distilled water will be placed onto the volar aspect of both forearms after the skin has been scratched with a scratch lancet. The distilled water in which the cat hair was solved before will serve as negative control. This procedure will be repeated with fur of the three different areas of the cat, always using triplicates (nine samples per cat). From each of the 20 cats, nine samples will be tested on 20 subjects (one cat/subject).
Patients with Parkinson's disease (PD) will be trained using a cognitive behavioral group-training-program to reduce stress and augment quality of life. An unspecific group with the same amount and frequency of meetings is used as a control group. For the evaluation of the training effects, scales to assess quality of life, analyses of psychopathological variations as well as neurocognitive tests will be used. Protocol amendment in 1-2017: addition of FU year 3 and year 5.
