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.
Objectives: - To find out if the chance of developing a serious illness or of getting AIDS is less if patients start taking HIV medicines at a time when their cluster-of-differentiation-4 (CD4)+ cell count is still fairly high, instead of waiting until the CD4+ count is at the level where there is good evidence for starting medicines. - To learn more about how a strategy of starting HIV medicines early might affect other aspects of care, such as the chances of developing other illnesses or resistance to HIV medicines, the frequency of doctor visits, the cost of medical care, and general health and satisfaction.
The purpose of the study is to characterize innate immune function of premature infants, and identify defects that may be responsible for the development of bacterial sepsis.
To evaluate long-term safety (primarily by recording adverse events including inhibitors), efficacy and patient acceptance of KOGENATE Bayer in home treatment either on prophylaxis or on demand. To evaluate both safety and efficacy with respect to lot variability, in particular regarding lot-groups formulated with or without fix between.
Patients who have completed the 12 weeks treatment of the PATENT-1 trial (study number 12934) will be asked to participate in this long term extension study with BAY63-2521.
An open, multicenter, randomised, parallel group pilot study to investigate two different polyclonal rabbit immunoglobulin preparations for safety and efficacy: A comparison of ATG-Fresenius S to Thymoglobulin in prophylaxis for immunological high risk patients following renal transplantation. This non-inferiority trial shall demonstrate that ATG-Fresenius S is as efficacious as Thymoglobulin but has a better tolerance and fewer side effects.
Aspirin is very common in older patients. Therefore many of the investigators patients have aspirin. The aim of the study is to proof that Transurethral Surgery of the bladder or the prostate can be performed with aspirin.
Objective: To assess the impact of instructional guidance in the regular use of use nicotine nasal spray (NNS) on the true use of NNS during the first three weeks of smoking cessation for heavy smokers who are willing to quit. Methods: This randomized, open, controlled trial included 50 patients who were heavy smokers, were willing to quit, and attending an academic outpatient clinic in Western Switzerland. Patients were randomised to instruction on NNS use as "ad libitum" (administration whenever cravings appear; control group) or to use NNS at least every hour when awake (intervention group). Intakes were monitored using an electronic device fixed in the spray unit (MDILogTM) during the first three weeks of use. Self reported abstinence from smoking at six months was confirmed by expired-air carbon monoxide. Using intention-to-treat analysis, random-effect GLS regression was used to calculate the mean difference of daily doses between groups controlling for lack of independence between measures from the same individual.
Study purpose is to evaluate if subjects with chronic obstructive pulmonary disease (COPD) are more likely to be responsive to additional inhaled corticosteroids if they have a positive response to hyperosmolar challenge with mannitol than if their response is negative.
The clinical investigation is designed as a prospective and non-randomised study on a maximum of 150 patients. This study will be conducted at Investigational Centres in the European Community. A minimum number of 8 European Centres will be involved in the clinical investigation. A minimum of 15 patients will be enrolled at each Investigational Centre. The clinical follow-up requires evaluations at discharge (or 30 days if the patient is still hospitalized), 3-6 and 12 months following the procedure.The primary objective of this clinical investigation is to assess the performance of the Perceval S valve at 3-6 months after implantation in high surgical risk patients, who require a surgical intervention to replace the aortic valve.
The prevalence of patent foramen ovale (PFO) is about 25% in the general population and approximately 40% in patients who have ischemic stroke of unknown cause (cryptogenic stroke). Given the large number of asymptomatic patients, no primary prevention is currently recommended. On the contrary, secondary prevention is very important. Prospective studies have shown that antithrombotic treatment (ATT) with aspirin or warfarin appears to negate the risk of recurrent stroke associated with a PFO. Patients with spontaneous or large right-to-left shunts (RLS), those with a coinciding atrial septal aneurysm (ASA) or multiple ischemic events prior to the PFO diagnosis may still be at increased risk of stroke recurrence despite ATT. Percutaneous device closure (PDC) is a challenging alternative to ATT. Several studies reported 0% to 3.4% annual recurrence rates of stroke or TIA in patients treated by PDC. To date, there is no data from randomized controlled trials (RCT) comparing the risk of stroke recurrence after PDC with that under ATT only. The results from ongoing RCTs are not to be awaited in the near future, mainly due to low enrolment and event rates. Alternative data-gathering strategies such as multicenter registries are needed to overcome the low recruitment rates. The aim of the present study is to compare the risk of recurrent stroke and TIA in patients with PFO and otherwise unexplained stroke who undergo PDC or receive ATT.
