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.
Non diabetic patients on renal replacement therapy are prone to changes in body composition with an increase in visceral fat and muscle wasting all favoured by the insulin resistant state. Malnutrition is associated with a worst prognosis in these patients. Glitazones are the most powerful insulin sensitisers available in clinical practice which also have anti-inflammatory properties. Their use has been associated with significant and favourable changes in body fat distribution in type 2 diabetic subjects. Experimental studies suggest that glitazones may attenuate muscle wasting in renal failure. The goal of this study was to examine in non diabetic ESRD patients the effects of pioglitazone on inulin sensitivity and protein metabolism as determined by the hyperinsulinemic euglycemic clamp and on changes in body composition as determined by anthropometric measurements, dual energy X-ray absorptiometry (DEXA) and CT-scan determined changes in abdominal visceral and sub-cutaneous fat.
This Phase IIb study is designed to assess whether 3 doses of AFQ056 are safe and effective in treating the behavioral symptoms of Fragile X Syndrome.
This open-label study will assess the safety and efficacy of RO5185426 in previously treated metastatic melanoma patients with brain metastases. Patients will receive RO5185426 at a dose of 960 mg twice daily orally until disease progression or unacceptable toxicity occurs.
This study monitors the intraocular pressure (IOP) over 4 to 6 hours using the SENSIMED Triggerfish® device and Goldmann Applanation Tonometry (GAT) in pigment dispersion syndrome and pigmentary glaucoma patients. The aim of the study is to detect SENSIMED Triggerfish® output signal peak after induced fluctuation by physical exercise or pupil dilation.
This study will investigate the effects of particle size of different triglyceride emulsions as well as the dynamics of intragastric structure formation and breakdown of the emulsions on GI function, the kinetics of the endocrine and the satiation response in healthy volunteers. 12 healthy participants will be studied on four occasions on four separate days in a double blind randomized design
Aim of this trial is to investigate the expression and localisation of different amino acid transporters and their regulatory proteins derived from the regulatory proteins of the local renin angiotensin system (RAS) in the intestine. This is investigated on one hand in patients who do not take any drugs interfering with RAS. On the other hand expression analysis is done in patients taking daily RAS-active drugs, like ACE inhibitors or sartanes. After obtaining informed consent of patients attending the hospital for clarification of gastrointestinal symptoms by gastroduodenoscopy or colonoscopy, 2 biopsies (in addition to biopsies needed for clinical diagnostics) will be taken from each duodenum, jejunum, ileum and descending colon. Biopsies are investigated anonymously at the Institute of Physiology of the University of Zurich. The mRNA content of amino acid transporters and regulatory proteins, respectively, in the biopsies is analyzed by quantitative PCR. Transport proteins are in addition analyzed with immunohistochemistry. Furthermore amino acid concentration in plasma and urine samples are analyzed by HPLC. From plasma and serum samples RAS parameters like renin, aldosterone, ACE and angiotensin(1-7) are measured.
Cognitive impairment is seen in about half of patients with relapsing remitting MS. Our knowledge about long term development of cognitive performance under natalizumab therapy is limited. We want to demonstrate with this study that patients treated with ntz improve in neurocognitive tests over the long term.
This study is a cross sectional study of patients diagnosed with clinically isolated syndrome (CIS) and RRMS, who will undergo a series of tests to assess cognitive impairment, fatigue severity and depressive symptoms. Cognitive impairment will be assessed with Multiple Sclerosis Inventory Cognition (MUSIC) and symbol digit modalities test (SDMT), fatigue severity will be measured with the Fatigue Scale for Motor and Cognitive Functions (FSMC) and depressive symptoms with the Beck Depression Inventory (BDI). All tests mentioned above are validated for MS patients. In the second step we will use our large longitudinal database of serial MRI examinations from which a linear measurement of CCI will be retrospectively calculated.
This randomized, open-label, parallel-group study will assess the efficacy and s afety of Avastin (bevacizumab) in combination with chemotherapy versus chemother apy alone as second- and third-line therapy in patients with locally recurrent o r metastatic breast cancer progressing after first-line therapy with Avastin and chemotherapy. Patients will be randomized to receive either Avastin (15 mg/kg e very 3 weeks or 10 mg/kg every 2 weeks intravenously) plus standard chemotherapy or chemotherapy alone. Anticipated time on study treatment is until third-line disease progression or unacceptable toxicity occurs.
The F2-study is a complement of the previous studies of the Follicular Lymphoma Prognostic Factors Project which permitted the development of the Follicular Lymphoma International Prognostic Index (FLIPI). The F2-study is designed as a prospective collection of information potentially useful to predict the prognosis of newly diagnosed Follicular Lymphoma patients, and its purposes are to validate the FLIPI and to verify whether a prognostic collection of data would allow the development of a more accurate prognostic index.
