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 objectives of this study are: (1) to evaluate the safety and tolerability of VP 20621 dosed orally for up to 14 days in adults previously treated for CDI; (2) to characterize the frequency and duration of stool colonization with the VP 20621 strain of C. difficile; (3) to evaluate the efficacy of VP 20621 for prevention of recurrence of CDI; and (4)to select a dose regimen of VP 20621 to be used in future studies.
Patients suffering from non small cell lung cancer(NSCLC), depend upon lung removal to increase their chances of survival. But, this type of surgery cannot be advised to patients with significant heart disease, limited lung fuction or reduced physical fitness. Intensive physical training has been shown to increase aerobic fitness in healthy subjects. The purpose of this study is to determine the effect of a short term rehabilitation prior to surgery on the post-operative and physiological outcomes for patients undergoing this type of surgery.
The purpose of this study is to analyze the peri-operative expression of pancreatic stone protein and pancreatitis-associated protein in surgical patients following major abdominal surgery by blood samples.
Computed tomography pulmonary angiography (CTPA) is the imaging method of choice to rule out acute pulmonary embolism based on its high sensitivity and specificity. Unfortunately, CTPA uses iodinated contrast media and can provoke contrast induced nephropathy. On the other hand, Computed tomography uses ionising radiation and is responsible for the half of the radiation exposure coming from medical sources. Recent studies have proven that low-dose CTPA protocols using Computed tomography tube energy of 80 kVp and reduced volume of iodinated contrast media provide an increased vessel signal and good image quality at a significantly reduced patient exposure. However, there are no data on the sensitivity of low-kVp protocols. The aim of this prospective randomized trial is to detect any difference between a normal-dose and a low-dose CTPA protocol in the diagnostic accuracy in the detection of acute pulmonary embolism (PE).
Test the correlations between the pharmacogenetic and pharmacokinetic of Busulfan IV in children receiving hematopoietic stem cell transplantation.
Hereditary thrombotic thrombocytopenic purpura (Upshaw-Schulman syndrome) is a rare disorder characterized by thrombocytopenia as a result of platelet consumption, microangiopathic hemolytic anemia, occlusion of the microvasculature with von Willebrand factor-platelet-thrombic and ischemic end organ damage. The underlying patho-mechanism is a severe congenital ADAMTS13 (a disintegrin and metalloproteinase with thrombospondin type 1 motif, 13) deficiency which is the result of compound heterozygous or homozygous ADAMTS13 gene mutations. Although considered a monogenic disorder the clinical presentation in Upshaw-Schulman syndrome patients varies considerably without an apparent genotype-phenotype correlation. In 2006 we have initiated a registry for patients with Upshaw-Schulman syndrome and their family members to identify possible triggers of acute bouts of TTP, to document individual clinical courses and treatment requirements as well as possible side effects of long standing plasma substitution, e.g. alloantibody formation or viral infections.
The purpose of this study is to demonstrate the (statistical) non-inferiority of iobitridol (Xenetix® 350) when compared to contrast agents with higher iodine concentrations, iopromide (Ultravist® 370) and iomeprol (Iomeron® 400) in terms of coronary CT scan evaluability (quality and interpretability of images).
This is a study to assess long-term safety and efficacy of lersivirine in patients who have completed 96 weeks of treatment with lersivirine in studies A5271015 and A5271022.
The purpose of the e-BioMatrix PMS registry is to capture clinical data of the BioMatrix (Biolimus A9-Eluting) stent system in relation to safety and effectiveness.
This is a double-blind prospective randomized monocenter study comparing the efficacy of two phototherapy ultraviolet spectra on pruritus (itching) of inflammatory skin diseases. 40 patients per treatment, in total 80 study participants.
