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.
Allergy is a public health problem as more than 20% of western society is affected by it. Symptomatic treatment of allergy suffices with less severe allergy. Patients with more severe allergy should be treated with allergen immunotherapy (AIT). Present options of AIT are efficient but of long duration, associated with side effects and require much time from the patient. With Intralymphatic immunotherapy (ILIT), allergen is injected into the lymph node under ultrasound guidance. ILIT is complete after 3 treatment visits, may be more effective than and may have markedly fewer side effects than presently available methods of AIT. The investigators plan a randomized, parallel group, open-label, prospective case-control study to assess immunological changes in lymph node and peripheral blood after intralymphatic (ILIT) or subcutaneous (SCIT) immunotherapy with POLVAC. The intervention consists of one ultrasound-guided injection of allergen into inguinal lymph node or subcutaneous injection 1 cm next to the lymph node. Intervention quality (accuracy of injection) will be assessed by the administering physician during treatment and via video recording on the ultrasound device. Side effects associated with treatment will be recorded by the patients for 3 days after the injection. The effect of intralymphatic or subcutaneous injection on lymph node tissue and immunoglobulins E and G4 in serum as well as cellular analyses of lymph node tissue and peripheral blood will be determined in samples taken during the trial. The primary effect parameter is the effect of a single intralymphatic allergen injection on immunological parameters as well as allergen delivery to the lymph node as compared with a single subcutaneous injection.
The breath analysis (BreathSpec® device) data of all participants that were included into the VAARA study (NCT05771090) will be analysed, this includes data from up to 40 breath samples from each of the 10 participants who underwent 2 insulin-induced hypoglycaemic episodes during two visits. The primary objective is to find a possible association between volatile organic compounds (VOCs) measured by the BreathSpec® device and blood glucose. For this we will use descriptive statistics, correlation coefficients, as well as a Principal Component Analysis and a partial least squares discriminant analysis. Furthermore, the time lag between hypoglycaemia onset and change in VOCs will be quantified.
Children with clubfeet who were exclusively treated by Ursula Issler-Wüthrich for 3 to 14 years with manual-dynamic physiotherapy and their healthy twin siblings are compared using gait analysis. GaitUp sensors (kinematic) and footscan V9 (kinetic) are the systems used for this comparison. Nonparametric statistics are applied to verify aberrations.
This study is an interventional, randomized, multinational, multicenter, double-blind, phase 2 study with a follow-up period of circa 12 months. The intension of this clinical trial is to investigate the long-term sequelae (named Long COVID syndrome; post COVID or PASC) of an infection with Corona Virus Type 2 that has resulted in a condition known as Severe Acute Respiratory Syndrome Corona Virus Type 2 (SARS-CoV-2). The purpose of this study is to evaluate the efficacy and safety of BC 007 as a treatment for long-lasting COVID-symptoms in patients who were neither intubated nor supported with extracorporeal blood oxygenation (ECMO) during their acute COVID-19 infection. The study drug acts by neutralizing functional autoantibodies directed against G-protein coupled receptors (GPCRs). Neutralization of the autoantibodies is expected to induce a beneficial effect on symptoms typically seen in patients with long COVID syndrome. Functional autoantibodies are proteins belonging to the class of G-type immunoglobulins that can be synthesized by activation of the immune system and can induce various pathogenic activities by binding to one of the extracellular loops of G-proteins (GPCR-AAB). The study consists of a screening phase of up to 35 days, treatment (two administrations by intravenous infusion at two-week intervals either with the study drug (BC 007) or with placebo (NaCl 0.9%), with an initial follow-up period of 15 days after each administration and an extended follow-up period of 330 days. Patients are required to visit the study center for follow-up visits at specified intervals. For the entire study duration of 395 days from screening to the end of the study, 11 site visits are planned.
The purpose of this study is to understand the safety and effects of the study medicine ARV-471 (PF-07850327) given together with palbociclib in advanced breast cancer. In particular, the study will compare the combination of ARV-471 plus palbociclib to standard of care therapy (letrozole plus palbociclib). Both letrozole and palbociclib are medicines already used for treatment of breast cancer. ARV-471 is a new medicine under study. This study is seeking participants who have breast cancer that: - Have a locally advanced or metastatic disease and cannot be fully cured by surgery or radiation therapy. A metastatic disease is when disease has spread to other parts of the body. - Is sensitive to hormonal therapy such as tamoxifen. This is called estrogen receptor positive disease. - Have not received any prior medicine for advanced disease. Example medications include tamoxifen or letrozole or exemestane. The study will have an open-label SLI (study lead-in) before initiation of Phase 3 trial. During SLI, two dose levels of palbociclib in combination with ARV-471 will be explored in parallel. Assignment to the palbociclib dose is by chance. Half of the participant will receive one dose and the other half another palbociclib dose. The purpose of SLI is to determine the recommended Phase 3 dose of palbociclib to be administered in combination with ARV-471. In the Phase 3, half of the participants will take ARV-471 plus palbociclib while the other half will take letrozole plus palbociclib. In both SLI and Phase 3, participants will take the study medicines by mouth, with food, once a day. Participants will take the study medicines until breast cancer increase in size or side effects become too severe. Side effects refer to unwanted reactions to medications. Participants will visit the study clinic about once every 4 weeks.
The goal of this study is to develop a prognostic score for ischemic posterior circulation strokes, based on our previous work on with the ASTRAL scores (Acute STroke Registry and Analysis of Lausanne) on overall stroke prognosis, intracranial occlusion, recanalization and stroke recurrences. The main question it aims to answer is the modified Rankin score in 3 months after the event. Participants will be patients with acute ischemic stroke of the posterior circulation with mRS priot to event <3. All the data will be collected retrospectively from patients included in the ASTRAL registry between January 2003 and December 2021. The ASTRAL registry will be used as the derivation cohort of the score. Demographics, acute glucose, NIHSS score and acute imaging of each participant will be used from the derivation cohort in order to create an integer-based prognostic score. After internal validation, we plan to validate the score in external stroke registries to show its validity.
The study is being conducted to understand how the medicine, semaglutide, affects the immune system and other biological processes in people with Alzheimer's disease. Semaglutide is a medicine that doctors can prescribe in some countries for the treatment of type 2 diabetes and excess body weight. This study will help us understand whether semaglutide can also be used for the treatment of Alzheimer's disease. The study will last for about 77 weeks. In the first 12 weeks of treatment, participants will either get semaglutide (active medicine) or placebo (inactive dummy medicine). Which treatment participants get is decided by chance. In the following 52 weeks of treatment, all participants taking part in the study will get semaglutide. Participants must have a study partner, who is willing to take part in the study. Participants will get study medicine in a pen injector. The study partner will need to inject the study medicine into the skin of participant's stomach, thigh or upper arm once every week.
The study will explore the performance of the CDMS (Cryo Detector Mass Spectrometer) method in measuring SF (serum ferritin) in human serum of healthy individuals. This will be the first experience of testing SF with this method using biologic material of human origin.
All enrolled participants will be randomized to 3 cohorts with 8 participants each and will receive BAP5191 and placebo topically on a square of 121 cm2 each in the left and right scapula region daily for 28 days, with a 28-d safety follow-up. The squares will be covered with a semi-occlusive patch. The doses will escalate from Cohort 1 to Cohort 2 to Cohort 3.
Tumour lysis syndrome (TLS) occurs as a consequence of the rapid destruction of malignant cells, spontaneously and/or in response to cytotoxic agents and immunotherapies. TLS is a feature of highly proliferative diseases with heavy tumor burden, such as high-grade non-Hodgkin lymphomas (NHL, typically Burkitt's lymphoma). We evaluated fractionating first rituximab dose to prevent TLS in a real-life B-cell NHL cohort of patients treated at University Hospital of Geneva between 2010 and 2020.
