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 world is currently facing a pandemic with the coronavirus (SARS-CoV-2) which leads to the disease of COVID-19. Risk factors for a poor outcome of COVID-19 have so far been identified as older age and co-morbidity including chronic respiratory conditions such as chronic obstructive pulmonary disease (COPD) and current smoking status. Previous studies found, that vitamin D deficiency is more prevalent among patients with these risk factors. There are observational studies reporting independent associations between low serum concentrations of 25-hydroxyvitamin D (the major circulating vitamin D metabolite) and susceptibility to acute respiratory tract infection. Vitamin D substitution in patients with COVID-19 who show a vitamin D deficiency should therefore be investigated for efficacy and safety. The study is designed as a randomized, placebo-controlled, double blind study. The objective of the study is to test the hypothesis that patients with vitamin D deficiency suffering from COVID-19 treated under standardized conditions in hospital will recover faster when additionally treated with a single high dose of vitamin D compared to standard treatment only.
Crohn's disease (CD) is a long-lasting condition causing inflammation that can affect any part of the gut. This study will evaluate how well risankizumab works compared to ustekinumab. This study will assess change in Crohn's Disease Activity Index (CDAI). Risankizumab is an investigational drug being developed for the treatment of Crohn's Disease (CD). Ustekinumab is an approved drug for the treatment of moderate and severe CD. Participants are randomly assigned to one of the three treatment groups. Each group receives a different treatment. There is a 1 in 2 chance that participants will be assigned to ustekinumab. Around 508 adult participants with moderate to severe CD will be enrolled in approximately 307 sites worldwide. In Part 1, participants assigned to risankizumab will receive intravenous (IV) doses of risankizumab at Week 0, 4,8 and subcutaneous (SC) doses every 8 weeks thereafter through Week 48. Participants assigned to ustekinumab will receive intravenous (IV) dose of ustekinumab at Week 0 and subcutaneous (SC) doses every 8 weeks thereafter through Week 48. In Part 2, participants who received risankizumab in Part 1 and completed the Week 48 visit will continue to receive SC risankizumab for up to an additional 220 weeks. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.
This study is to find out what role a local intestinal RAS (renin angiotensin system) plays in the context of amino acid absorption in the human intestinal tract and how this RAS and thus the amino acid absorption is influenced by the RAS-active drugs (angiotensin II AT1 receptor blockers (sartans) or ACE inhibitors).
The investigators want to study whether the use of painting art therapy has an influence on the quality of life, the complication rate and the general outcome of major abdominal surgery. The painting art therapy is carried out according to the protocol of (LOM® Solution Centered Art Therapy) by trained painting art therapists.
This study will assess iodine status in school aged children and pregnant women is Switzerland. In addition, thyroid status and omega-3 index will be assessed in pregnant women.
Bile leakage (BL) is the most frequent complication after liver resection. This study is to investigate the role of intraoperative administration of SMOFlipid 20% (fat emulsion which allows intraoperative identification of open bile ducts at the liver resection surface when it is administered retrograde through the cystic duct) in terms of prevention of postoperative BL within 30 days after surgery.
Negative pressure dressings are currently widely used in wound management. Their use is gradually being extended to surgical scars. However, studies demonstrating a clear benefit are rare, particularly in terms of postoperative discharge, the need for surgical revision due to prolonged oozing and cost. The aim of this study is to evaluate the benefit of such a device in post-operative revision prosthesis surgery (hip and knee), as well as lower limb amputations.
To evaluate the acute effects of respiratory muscle exercises vs. a control intervention on blood glucose kinetics in healthy adults after an oral glucose tolerance test.
This observational study with circulating tumor cells (CTC) count, isolation and analysis at several time points during disease progression is to investigate the role and biology of CTCs and clusters of CTCs in different cancer types. It also evaluates the role of CTCs as biomarkers, and aims at the identification of key signaling networks that are active in CTCs.
The proportion of asymptomatic carriers of SARS-CoV-2 remains elusive, so the potential benefit of systematic screening during the SARS-CoV-2-pandemic is controversial. We investigate the proportion of asymptomatic inpatients who were identified by systematic screening for SARS-CoV-2 upon hospital admission. Adult patients admitted to the University Hospital Basel from 01.04.-14.06.2020 were routinely tested for SARS-CoV-2 within 72 hours of admission by nasopharyngeal swabs. Each patient screened during the study period was retrospectively classified symptomatic or asymptomatic for COVID-19 based on medical chart review.
