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.
In the last 10 years, severe acute respiratory infection (SARI) was responsible of multiple outbreaks putting a strain on the public health worldwide. Indeed, SARI had a relevant role in the development of pandemic and epidemic with terrible consequences such as the 2009 H1N1 pandemic which led to more than 200.000 respiratory deaths globally. In late December 2019, in Wuhan, Hubei, China, a new respiratory syndrome emerged with clinical signs of viral pneumonia and person-to-person transmission. Tests showed the appearance of a novel coronavirus, namely the 2019 novel coronavirus (COVID-19). Two other strains, the severe acute respiratory syndrome coronavirus (SARS-CoV) and Middle East respiratory syndrome coronavirus (MERS-CoV) have caused severe respiratory illnesses, sometimes fatal. In particular, the mortality rate associated with SARS-CoV and MERS-CoV, was of 10% and 37% respectively. Even though COVID-19 appeared from the first time in China, quickly it spread worldwide and cases have been described in other countries such as Thailand, Japan, South Korea, Germany, Italy, France, Iran, USA and many other countries. An early paper reported 41 patients with laboratory-confirmed COVID-19 infection in Wuhan. The median age of the patients was 49 years and mostly men (73%). Among those, 32% were admitted to the ICU because of the severe hypoxemia. The most associated comorbidities were diabetes (20%), hypertension (15%), and cardiovascular diseases (15%). On admission, 98% of the patients had bilateral multiple lobular and sub-segmental areas of consolidation. Importantly, acute respiratory distress syndrome (ARDS) developed in 29% of the patients, while acute cardiac injury in 12%, and secondary infection in 10%. Invasive mechanical ventilation was required in 10% of those patients, and two of these patients (5%) had refractory hypoxemia and received extracorporeal membrane oxygenation (ECMO). In a later retrospective report by Wang and collaborators, clinical characteristics of 138 patients with COVID-19 infection were described. ICU admission was required in 26.1% of the patients for acute respiratory distress syndrome (61.1%), arrhythmia (44.4%), and shock (30.6%). ECMO support was needed in 11% of the patients admitted to the ICU. During the period of follow-up, overall mortality was 4.3%. The use of ECMO in COVID-19 infection is increasing due to the high transmission rate of the infection and the respiratory-related mortality. Therefore, the investigators believe that ECMO in case of severe interstitial pneumonia caused by COVID could represent a valid solution in order to avoid lung injuries related to prolonged treatment with non-invasive and invasive mechanical ventilation. In addition, ECMO could have a role for the systemic complications such as septic and cardiogenic shock as well myocarditis scenarios. Potential clinical effects and outcomes of the ECMO support in the novel coronavirus pandemic will be recorded and analyzed in our project. The researchers hypothesize that a significant percentage of patients with COVID-19 infection will require the utilize of ECMO for refactory hypoxemia, cardiogenic shock or septic shock. This study seeks to prove this hypothesis by conducting an observational retrospective/prospective study of patients in the ICU who underwent ECMO support and describe clinical features, severity of pulmonary dysfunction and risk factors of COVID-patients who need ECMO support, the incidence of ECMO use, ECMO technical characteristics, duration of ECMO, complications and outcomes of COVID-patients requiring ECMO support.
The goal of this project is to develop the international validation of two new rating scales, the Neuropsychiatric Fluctuations Scale (NFS) and the Shame in PARKinson's disease (SPARK) Scale, in order to improve the understanding of the extent and severity of non-motor symptoms in Parkinson's disease (PD).
The COVID-19 pandemic poses a major and imminent challenge for health care systems regarding patient triage and allocation of limited resources worldwide. The involved pathogenetic mechanisms as well as the clinical value of established and emerging biomarkers for early risk prediction are largely unknown. To fill these gaps in knowledge, investigators designed the prospective, interdisciplinary, observational, case-control "COronaVIrus surviVAl (COVIVA)" study platform, aiming to deliver an open-source platform to i) perform extensive clinical and biomarker phenotyping in COVID-19 suspects presenting to the emergency department (ED) as well as admitted to the intensive care unit, ii) compare clinical and biomarker profiles of COVID-19 patients with a control group, iii) derive and validate personalized risk prediction models for early clinical decision support, and iv) explore pathophysiological mechanisms including but not limited to inflammatory, immunological and cardiovascular pathways. Blood samples (serum) are routinely collected for bio banking both in cases and controls. Patients are followed 30 days after discharge. Personalized risk prediction models will be derived and validated based on advanced statistical models including machine-based learning incorporating a variety of clinical parameters and biomarker signatures (including digitally stored in-hospital data, e.g. imaging, ECG, ventilation parameters). Close cooperation with multiple other national and international COVID-19 cohorts is endorsed. The personalized risk prediction models from the COVIVA study will support clinicians in the most challenging process of limited resource allocation in a timely fashion. In addition, pathophysiological mechanisms and differences in mild and severe variants of COVID-19 as well as in the control group can be extensively studied in a multidisciplinary approach.
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the cause of the current pandemic of coronavirus disease (COVID-19) that can lead to respiratory failure requiring oxygen therapy. Some patients develop acute respiratory distress syndrome (ARDS) and may die despite intensive care therapy. Currently it is unknown a) how fast patients recover after being discharged from hospital and b) what underlying predictors may influence recovery.
The purpose of this proof of concept study is to provide COVID-19 convalescent plasma to patients with moderate to severe COVID-19 and assess: - the titer of anti-COVID-19 antibodies in the donors and in the patients before and after treatment; - the in-depth analysis of immunological parameters in the donors and in recipient before and after treatment; - the impact of plasma transfusion on the reduction of viral load and inflammation - safety and tolerability - clinical efficacy
To assess the efficacy and safety of orally administered Epeleuton capsules versus placebo, in the treatment of adult patients with hypertriglyceridemia and type 2 diabetes
The overall purpose of the study is to investigate effect of Digitally Supported Home Exercises (DSHE) in different groups for which digitally supported interventions could be beneficial. Balance is altered in individuals with low back pain and requires intervention Thus, the investigators will focus on the effect of DSHE to improve postural balance.
A study to assess, in a two-arm open-label cluster randomized clinical trial, the efficacy of a 5-day course of LPV/r treatment in preventing COVID-19 in asymptomatic individuals exposed to a SARS-CoV-2 documented index patient, compared to surveillance alone.
Fundoscopy, optical coherence tomography (OCT) and OCT-angiography (OCTA) are established examinations and bear minimal risks. The recognition of retinal microvascular signs will enhance the pathophysiological understanding of the vasculopathy in patients with intracerebral haemorrhage (ICH) and aneurysmatic subarachnoid hemorrhage (aSAH) and might serve as prognostic and diagnostic indicators.
This clinical phase II study is designed to investigate the efficacy of intratumorally administered L19IL2/L19TNF in patients with injectable lesions of BCC or cSCC. Favorable tumor responses following intralesional treatment with L19IL2/L19TNF have been observed in patients with injectable melanoma lesions of stage III or IV, for injected and non-injected lesions. The proposed clinical phase II study plans to investigate the intralesional administration of 6.5 Mio IU of L19IL2 (~1.08 mg) and 200 µg of L19TNF to be administered in an approximate volume of 1.0 mL as a single or multiple intratumoral injections in patients with high-risk BCC or cSCC. There is a high medical need for non-invasive therapeutic strategies with a comparable good response rate and high recurrence free survival for treatment of patients with BCC or cSCC, who cannot be treated by or refuse surgery. Surgery is not always applicable, as it may not be feasible due to the anatomic location, may have a poor cosmetic outcome for the patient or is generally not accepted as treatment strategy by the patient. However, current non-surgical treatment strategies have a considerably reduced response rate and recurrence free survival. Based on the favorable results for injected and non-injected lesions obtained in the phase II study of L19IL2/L19TNF and the good safety profile seen in the subsequent phase III study, both in stage III or IV melanoma patients, we believe, that patients with BCC or cSCC will profit from intralesional treatment with L19IL2/L19TNF.
