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.
Stereotactic radiosurgery or hypofractionated radiotherapy of the resection cavity after metastasectomy in cancer patients with brain metastases
This is a longitudinal, observational study with the aims of comparing spinal cord gray matter areas in patients with Post-Polio Syndrome to age and sex matched healthy control subjects and to correlate atrophy with metrics of clinical disability.
Children having selective ophthalmic artery chemotherapy for retinoblastoma under general anaesthesia may experience troubles during the procedure. The troubles are transient, may be severe and include hypoxemia, hypotension and bradycardia. All children having such trouble always fully recovered without any sequelae or prolonged length of stay. The investigators suspect that these phenomenons are caused by transient pulmonary hypertension.The objective is to see whether transient pulmonary hypertension and right-sided heart failure is present during theses phenomenon by trans-thoracic echocardiography.
Hyponatremia is the most common electrolyte disorder with a prevalence of up to 30% in hospitalized patients. While treatment of acute hyponatremia with severe clinical symptoms due to cerebral edema is undisputed and straightforward, hyponatremia in general is usually considered asymptomatic or not clinically relevant. Accordingly, a recent observational study showed that appropriate laboratory tests to evaluate the etiology of hyponatremia were obtained in less than 50% of patients, leading to 75% of patients being still hyponatremic at discharge. This is problematic in the context of increasing evidence, revealing an association of chronic hyponatremia with adverse effects such as gait alterations and falls, attention deficits, bone loss and fractures as well as disease-associated morbidity leading to increased rates of readmissions and mortality. Yet, there is a complete lack of randomized clinical trials with the primary aim to investigate whether correction of plasma sodium concentration counteracts the elevated risk of rehospitalization and mortality. The aim of this trial is therefore to determine the effects on mortality and rehospitalization rate of a targeted correction of plasma sodium concentration in addition to current standard care in hospitalized hyponatremic patients.
This 2-part study will evaluate the safety and efficacy of pembrolizumab (MK-3475) compared to placebo in participants with surgically resected high-risk Stage II melanoma. Participants in Part 1 will receive either pembrolizumab or placebo in a double-blind design every 3 weeks (Q3W) for up to 17 cycles/~1 year (each cycle = 21 days). Participants who complete the initial treatment of 17 cycles of pembrolizumab in Part 1 and experience disease recurrence may be eligible for re-challenge with pembrolizumab at the same dose and schedule of 200 mg Q3W (21-day cycles) for up to 35 cycles (up to ~2 years) in Part 2 in an open label design. Participants who complete the initial treatment of placebo and experience disease recurrence may be eligible to switch over to pembrolizumab 200 mg Q3W (21-day cycles) for up to 35 cycles (up to ~2 years) in Part 2 in an open label design. The primary hypothesis of this study is that pembrolizumab increases recurrence-free survival (RFS) compared to placebo. Per protocol, response/ progression or adverse events (AEs) during re-challenge/switch-over in Part 2 will not be counted towards the RFS outcome measure or safety outcome measures respectively.
Some patients with limited disease small-cell lung cancer (LD SCLC) are cured after chemo-radiotherapy, but the majority relapse and die from their cancer. Better therapy is needed. Immunotherapy represents the largest advance in cancer therapy in recent years and has demonstrated promising activity in SCLC. In this study we will investigate whether atezolizumab prolongs survival in LD SCLC patients who have undergone chemo-radiotherapy.
This study is designed to identify the target Non-Small Cell Lung Cancer (NSCLC) population(s) that overexpress c-Met (c-Met+) best suited for telisotuzumab vedotin therapy in the second line or third line setting (Stage 1) and then to expand the group(s) to further evaluate efficacy in the selected population(s) (Stage 2). After the Stage 2 global enrollment is completed, an additional cohort at an alternate dose level will evaluate the safety and efficacy of telisotuzumab vedotin (Stage 3).
Analyse a multidisciplinary follow-up of amyotrophic lateral sclerosis patients, monitored through a Cohort study at Geneva University Hospitals.
This is a monocentric, prospective, interventional and translational phase II study. Metastatic melanoma (mMEL) patients who are naive to immune therapy in the metastatic setting, and for whom an anti-Programmed Cell Death-1 (PD-1) therapy is needed could be eligible. The aim of the study is to identify biological markers which allow to better understand and predict the tumor response to pembrolizumab treatment, and thus to establish more efficient treatments for selected patients. Eligible patients will be registered (n=30) and will be treated with pembrolizumab monotherapy at 200 mg every three weeks for 2 years maximum until progression, unacceptable toxicity, or withdrawal of consent, whichever happens first. Patients may be treated for up to one year of additional treatment with pembrolizumab via the Second Course Phase. Patients will be followed medically and radiographically during pembrolizumab treatment. Patients will be followed radiographically every 9 weeks (+/- 7 days) until progression and disease evaluation will be assessed by RECIST 1.1 criteria. After progression, patients will be followed every 6 months for 5 years to collect survival data.
Successful ambulation at home and in the community is the main goal of gait training after incomplete spinal cord injury. Many different treatment approaches have been recommended to achieve this goal. One established intervention to achieve that in a clinical setting is body weight supported (BWS) treadmill training. However, recent studies have suggested that the most optimal gait training should be conducted overground with appropriate support conditions to enable a physiological gait pattern. The training has to be challenging and patients must participate as active as possible. In addition becoming a functional walker in real world involves a variety of walking skills like walking on uneven surfaces, walking up and down slopes, climbing stairs and avoid obstacles. It has been shown in humans as well as in animals that greater improvements are achieved in walking function if the training is task specific. Thus a constrained task like BWS treadmill training may not be the optimal training intervention to become a functional community walker. Even greater improvements can be expected if patients feel safe during the overground walking and train at their individual limits. With FLOAT there is now the possibility to conduct a task specific BWS overground gait training in a safe environment. The robotic device allows patients to perform different walking tasks like walking overground, avoiding obstacles, walking on uneven and sloped surfaces, climbing stairs, walking in narrow spaces. A virtual reality setup was integrated into the system that even can simulate specific walking tasks like target oriented walking or walking in crowded environment. Based on the promising results seen in preclinical and clinical research, the investigators assume that unrestricted transparent BWS overground training that allows task specific training of real world walking tasks will induce greater improvements than conventional BWS treadmill training. The investigators will compare the effect of an intensive 4 weeks unrestricted BWS overground gait training to 4 weeks of intensive BWS treadmill training. Not only functional outcome like walking speed or capacity will be assessed but also detailed kinematics that will help to identify the mechanisms of the underlying improvements in walking function.
