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 primary objective of the preSponge randomized controlled trial (RCT) will be to assess the potential protective effects of preemptive endoscopic negative pressure therapy (ENP) on postoperative morbidity in high-risk patients undergoing total minimally invasive transthoracic esophagectomy with gastric pull-up reconstruction and high intrathoracic anastomosis (thoracoscopic and laparoscopic Ivor Lewis esophagectomy).
Investigation of the efficacy of a gamified augmented reality exposure app in individual with fear of spiders.
Cystoid macular edema (CME) can limit visual acuity after cataract surgery. Little is known whether the incidence is similar between standard ultrasound phacoemulsification cataract surgery (phaco), femtolaser assisted cataract surgery (FLACS), and combined phacoemulsification cataract surgery plus micro invasive glaucoma surgery (phaco+MIGS) procedures.
The main objective of this study is to evaluate the efficacy of venetoclax in combination with azacitidine to improve Overall Survival (OS) in Acute Myeloid Leukemia (AML) participants compared to Best Supportive Care (BSC) when given as maintenance therapy following allogeneic stem cell transplantation (SCT). This study will have 2 parts: Part 1 (Dose Confirmation), which may include participants who are greater than or equal to 18 years old; Part 2 (Randomization) which may include participants who are greater than or equal to 12 years old. During Part 1, recommended Phase 3 dose of venetoclax in combination with azacitidine will be determined and during Part 2, the efficacy and safety of venetoclax with azacitidine (Part 2 Arm A) will be compared with BSC (Part 2 Arm B).
This is a Post-Market Evaluation of the Zephyr Valve 5.5-LP EBV to assess Treated Lobar Volume Reduction (TLVR), changes in lung function and the safety profile of the Zephyr Valve treatment with the use of at least one Zephyr Valve 5.5-LP EBV.
The Genital Nerve Stimulation - GNS - consists of a two-step procedure with a preoperative non-surgical test-phase and a final surgical implantation of the neuroprothesis. In contrast to the classical technique of transcutaneous lead electrode implantation for sacral or pudendal nerve stimulation, the GNS-test-phase does not require any interventional procedure: because the genital nerves are located just few millimeter below the skin, test-stimulation can be achieved using skin surface or needle electrodes. Stimulation is achieved using a battery powered hand-held stimulator . The effect of the stimulation can be tested by the patient in their daily, home and professional environment, or at the practice under urodynamic testing, or if required other electrophysio-logical testing. After confirmation of the effectiveness of GNS, implantation of a permanent neuroprothesis can be planned. The procedure is performed either under general or spinal anesthesia or using only local anesthesia with IV-sedation as in the classical tension-free vaginal tape procedure (TVT). Because the GNS does not require two surgical procedures for both the test- and the final-implantation but rather only one for the final implantation, the presented protocol allows considerable cost reduction in comparison to the usual procedures for sacral or pudendal nerve stimulation.
Purpose of this prospective, randomized, controlled, multi-center study is to evaluate the safety and efficacy of Transcatheter Aortic Valve Implantation (TAVI) as compared to surgical aortic valve replacement (SAVR) in female patients with severe symptomatic aortic stenosis. Patients will be randomized 1:1 to receive either TAVI or SAVR aortic valve replacement. For TAVI procedure, Edwards SAPIEN 3 THV system Model 9600 TFX (20, 23, 26 and 29 mm) or SAPIEN 3 Ultra THV system Model 9750 TFX (20, 23, 26) with the associated transfemoral delivery systems will be sued, for SAVR any commercially available surgical bioprosthetic valve. Patients will undergo the following visits: Screening, Procedure, Post Procedure, Discharge, 30 day, 6 months (telephone contact) and 1 year.
Heart failure (HF) with preserved left ventricular function (pEF) is difficult clinical syndrome to treat effectively with few evidence based therapies. Atrial fibrillation (AF) is now an important co-morbidity being observed in 43% of patients with HFpEF. Rhythm control has not been studied in this population. Catheter ablation and antiarrhythmic drugs are rhythm control therapies that have been used for treatment of AF without HF or HF with reduced systolic function but have not been widely applied in HFpEF. No controlled comparative evaluation has been performed in HFpEF. The introduction of wireless pulmonary artery hemodynamic monitoring has permitted optimization of HF therapy in patients with chronic HF with reduced and preserved EF. Reduction in HF hospitalizations has been observed in post hoc analyses of HFpEF patients but has not been systematically applied in AF patients with HFpEF. In this study, we propose to study both rhythm control and optimized HF therapeutic approaches in an AF with HFpEF study population in a pilot study using a sequential two phase randomized controlled clinical trial design.
This is an observational case-control add-on study to an investigator-initiated clinical trial (IICT) (ClinicalTrials.gov Identifier: NCT03167307): Omega-3 fatty acids as firstline treatment in pediatric depression. A 36-week multi-centre, double-blind, placebo-controlled randomized superiority study. This project will recruit a healthy control group matched for age and sex to a sub-group of patients with diagnosed pediatric major depressive disorder (pMDD) enrolled in the IICT. The aim is to investigate the relationship of n-3 FA intake and status with mental health in children and adolescents with and without diagnosed pMDD, and explore potential biochemical mechanisms underlying this relationship by measuring biomarkers related to n-3 FA metabolism, mental health and cognitive function.
The purpose of this clinical trial is to assess the safety and efficacy of SDX-3101 for treatment of adult patients with chronic rhinosinusitis without nasal polyps (CRSsNP) by investigating a vibration pattern of SDX-3101 compared to a control
