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 therapeutic approach taken by trial SAKK 66/17 is different from those already used in clinical practice and possibly offers patients a therapeutic benefit after failure of standard chemotherapy and immunotherapy. Patients with laser ablation-accessible solid tumors are treated by thermal ablation followed immediately by an injection of IP-001. IP-001 is intended to trigger a tumor-specific systemic immune response when exposed to thermally liberated tumor antigens. There is strong preclinical and early clinical evidence that combining thermal ablation with IP-001 might be able to turn 'cold' tumors into 'hot' tumors, inducing a systemic immune response and resulting in shrinkage of the treated tumor including long-term response mediated by the patient's immunological defense system against any remaining tumor cells (residual primary and metastatic tumor cells) even those that are outside or distant from the treated area. This trial will provide information on the safety and tolerability of thermal ablation followed immediately by an intratumoral IP-001 injection (Ablation + IP-001) in patients with laser ablation-accessible solid tumors ('all comers', Part 1 - safety run in). Further information on safety and tolerability and as well preliminary antitumor activity will be evaluated in patients with soft tissue sarcoma (Part 2, Cohort1) and addition, in melanoma patients the anti-tumor activity will be defined as a primary objective (Part 2, Cohort 2). The trial treatment consists of an Ablation + IP-001 in 4-week intervals for up to six scheduled treatments. Thermal ablation will be performed according to the instruction of the medical device and IMP IP-001 will be administered in different dose levels according to the trial design. A follow up of all patients until progression of disease or until start of a subsequent treatment is part of the trial.
Neuraxial anesthesia has been associated with delayed brainstem conduction and decreasing afferent sensory transmission, thereby modifying reticulo-thalamo-cortical mechanisms regulating arousal. The state of entropy measured by EEG-monitors has detected sedative effects associated with neuraxial anaesthesia in healthy volunteers, as well as during caesarean delivery. Entropy is a measure of the irregularity or disorder of a brains activity - sedation leading to a decrease of irregularity or disorder in the EEG.The aim of this pilot study is to prospectively assess the effect of spinal anaesthesia in healthy and preeclamptic parturients on brain activity. Decreased epileptiform activity in patients with preeclampsia would suggest that early neuraxial analgesia in labouring preeclamptic patients is beneficial, and may protect against neurological complications.
The aim of the study is to evaluate the degree of refractive error postoperatively in combined procedures and to calculate a new constant in order to improve current state of the art biometry calculations.
Recent experiments in the lab of Prof. WD Hardt revealed, that in mice, 24 h exposure to a high-fat diet results in a breakdown of colonization resistance against Salmonella typhimurium. Mechanistic experiments identified bile acids as the mediator for reduced colonization resistance. Exposure to a high fat diet leads to increased bile acid secretion which in turn modify the intestinal microbiota. It is now the aim to verify the results of this study in human healthy volunteers. The nutritional habits of all participants will carefully be evaluated. In the intervention phase, participants will be exposed to either high-fat or low-fat diet and a controlled dose of the non-pathogenic bacteria E. coli Nissle. E. coli Nissle is the active compound for "Mutaflor®" and other probiotics. It is planned to enumerate E. coli Nissle counts in the stool after Mutaflor ingestion and to quantify other changes of the human microbiota. The hypothesis is that a high-fat diet leads to increased bile acid secretion results in favorable growth conditions for E. coli Nissle, resulting in high bacterial counts in the stool.
Optimal prescribing of antimicrobials is becoming increasingly challenging because of the growing complexity of guidelines and constantly changing distribution of infectious pathogens. Prescribing antimicrobials appropriately according to local guidelines optimizes therapy for the individual patient and reduces the emergence of resistance. By adapting and evaluating a smartphone based app containing local guidelines we aim to study appropriate prescribing of antimicrobials by physicians in three hospitals (Netherlands, Sweden and Switzerland).
Sustained, monomorphic ventricular tachycardia (VT) is most commonly encountered in patients with structural heart disease, usually with ischemic aetiology. It has been proven that repeated episodes of sustained VT contribute to the mortality of patients with structural heart disease. These patients are usually implanted with implantable cardioverter defibrillator without (ICD) or with cardiac resynchronisation therapy (CRT-D). According to the current guidelines 3D mapping with radiofrequency (RF) ablation of the tachycardia substrate is an established therapeutic option. As part of the clinical follow-up of patients implanted with cardiac implantable electronic devices (CIED), CIED function parameters are monitored every 6 months, which is always done before and after any procedure involving RF ablation. Furthermore, a transient drop of R wave sensing has been demonstrated after the atrioventricular (AV) node ablation in patients with single-chamber pacemakers and fast atrial fibrillation. The aim of this study is to assess the change in R wave sensing after the RF ablation of VT substrate. This study will be performed as a clinical, prospective, multi-centre, observational cohort study with a structured follow-up period of 12 months. All consecutive patients with sustained VT implanted with ICD or CRT-D undergoing RF ablation procedure of myocardial substrate, who are able to understand and sign informed consent, will be enrolled. Primary objective is a R wave sensing drop > 30% after VT substrate ablation procedure. Recruiting should not exceed 12 months with the minimal follow-up period of 12 months (24 months in total). Standardized statistical methods and test will be done using SPSS Software Version 22.0 or newer. This unique study offers the possibility to show the impact of RF ablation on short-term and long-term R wave sensing change assessed by ICD or CRT-D's ventricle electrode in patients with sustained VT and structural heart disease undergoing ablation procedure. This observational data is needed to further refine the treatment of these patients and to prevent possible ICD/CRT-D dysfunction which could endanger this patient population.
Prospective, single-center, open-label, single-dose, phase 1 study, to assess the effect of mild, moderate, and severe hepatic impairment due to liver cirrhosis on the Pharmacokinetics (PK) of ACT-541468
Recent in vivo studies from others as well as the investigators group demonstrated that volatile anesthetics immunomodulate sepsis and improve outcome. Also, several clinical trials have convincingly shown that application of a volatile anesthetic provides protection in patients undergoing major surgery. Patients with sepsis are intubated and ventilated and therefore need sedation. So far, most ICU centers use intravenously applied sedatives in these patients. In the proposed study, we will switch sedation from an intravenous to a volatile anesthetic for a short period of time to explore if sepsis markers improve within the following 120 hours upon sevoflurane conditioning.
For certain changes in the oral mucosa a histopathological examination of the affected tissue is indicated to confirm the diagnosis. The gold standard is the biopsy by scalpel. The aim of this study is to compare the alternative method of tissue sampling using the erbium doped yttrium aluminium garnet (Er:YAG) laser with the gold Standard.
