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.
Disruption of care during transition from child and adolescent mental health (CAMHS) to adult mental health services (AMHS) may adversely affect the health and well-being of service users. Indeed, transition-related discontinuity of care is a major health and societal challenge today. Current evidences show that this transition is not always properly managed and that improving the transition process can have a positive impact on the health and wellbeing of young people. Nevertheless, data available are still inconsistent and only few studies investigated possible models aimed at improving and operationalize the transition. At present, no information concerning the transition in the Geneva Canton is available. According to this lack of evidence, the current study aims at: 1) mapping the CAMHS/AMHS interface; 2) evaluating the longitudinal course and outcomes of adolescents approaching the transition boundary (TB) of their CAMHS; 3) determining the effectiveness of an experimental model of managed transition in improving outcomes, compared with usual care; 4) comparing these results with those of the EU funded MILESTONE study from several other European countries. The investigators will recruit all patients aged ≥ 16 years and 6 months from the Geneva Canton in charge at CAMHS and they will follow them for up to 24 months. CAMHS will be instructed to provide all their service users at the time of transition either usual care or a novel service called "Managed Transition", which will include the use of a new decision support tool, the Transition Readiness and Appropriateness Measure (TRAM). A nested cohort Randomised Controlled Trial (ncRCT) design will be applied to divide patients into the two groups. The health and wellbeing of the young people will be assessed at baseline and then followed-up for 24 months to see whether they transition to AMHS or are discharged or referred to some other service. The investigators will then evaluate what impact the different transition experiences have on young people's health and wellbeing, and whether the process of Managed Transition has any benefits as compared to usual care.
Despite its poor abundance in the liver, CYP2D6 is the second most important CYP in drug metabolism, metabolizing 20% of drugs. The high inter-individual variability in CYP2D6 expression is explained by genetic variations, but also by drug-drug interactions (DDIs). Recent studies have pointed out the poor therapeutic predictable value of DDI. Indeed, the clinical outcomes of a DDI may involve several intrinsic factors affecting the vulnerability to and extent of DDI, such as genetic polymorphisms, comorbidities, age and sex. In this regard, the present research project aims to investigate the effect of genetic polymorphism on DDIs involving CYP2D6 (gene-environment interaction) and its implications for tramadol efficacy and safety in a clinical setting. In a previous study, we demonstrated differences in both the rate of phenoconversion and the magnitude of DDI in healthy volunteers, that were either heterozygote normal metabolizers (NMs) carrying a non-functional CYP2D6 allele (activity score (AS) 1) and homozygous NM carrying two fully-functional CYP2D6 alleles (AS 2). This prospective study will include patients scheduled for a general surgery of less than 3 hours and planned to be treated with oral tramadol as a routine post-operative pain management. Patients taking part in the study may receive diagnosis, therapeutic or other interventions but the groups of individuals (controls vs inhibited) are predefined based on the routine treatment of the patients. There will be no assigned specific interventions to the study participants and CYP2D6 phenotypes will be classified in five activity score groups (0.5, 1, 1.5, 2, >2) in the absence or presence of a potent CYP2D6 inhibitor received as part of routine medical care. PK of tramadol and its active metabolite (M1), as well as its analgesic and PD effects and safety, will be compared between groups. Finally, the data generated will be used to build a physiologically-based PK (PBPK) model for tramadol in different sub-groups. The model will aim to predict the effect of CYP2D6 inhibition in virtual populations with different genetically-related CYP2D6 activities. This should allow prospective dose adjustment of tramadol (or appropriate drug selection) based on patients' genotype in the presence of a CYP2D6 inhibitor.
One prospective observational study was carried out in 2009 aiming at identifying the fluctuations of the thyroid hormones in women with normal thyroid gland and in women with anti-TPO antibodies. Serum samples were collected periodically during and after pregnancy in previously infertile women. The samples were stored frozen at -80 °C. Now, the hormone measurements will be carried out.
The purpose of the study is to assess the efficacy and safety of ravulizumab for the treatment of adult participants with ALS.
lnborn errors of metabolism (IEM) are a heterogeneous group of rare, sometimes debilitating or even fatal diseases . In IEM, both definition and assessment of meaningful outcome parameters is often extremely difficult resulting in a limited body of evidence. Limited evidence results in weak recommendations which are perceived as unbinding and thus sustains heterogeneous study designs, choice of outcomes and interventions again producing non-uniform data. The goal of the current study is to identify and select reliable instruments, that measure patients' and their parents' perception about relevant (social, emotional, cognitive and physical) aspects in their lives. This set of instruments will secure the comparability of future research findings. Furthermore this instruments will improve the screening of paediatric IEM patients regarding their need for additional (psychosocial or consultative) support in daily hospital routine.
Multi-arm, multi-center, open label, prospective observational registry designed to obtain safety and performance data on the use of CE marked and custom Terumo Aortic endovascular grafts.
In the present study, the investigators aim to use the in-vivo Transcatheter Mitral Valve Repair (TMVR) model to determine how Mitral Regurgitation (MR) affects coronary hemodynamics in patients affected with severe MR and concomittant angiographically-documented coronary artery disease. The investigators will also provide unique physiologic data on the acute effect of TMVR using the MitraClip system on coronary microcirculation in patients with severe MR.
Resectable, locally advanced NSCLC with involvement of mediastinal lymph nodes (N2) is associated with a high risk of (systemic) recurrence despite neo-adjuvant chemotherapy. Neo-adjuvant immunotherapy is a promising additional treatment modality aiming at increasing local control and better tackling micrometastases at the time of radical local treatment. Radiotherapy is thought to act synergistically with immunotherapy through release of tumor antigens and modulation of the local immune microenvironment in favor of a better antigen-presentation and (systemic) anti-tumor immune response (abscopal effect). The aim of the proposed SAKK 16/18 trial is to evaluate the efficacy and safety of adding immune-modulatory radiotherapy to the SAKK 16/14 treatment regimen by combining neo-adjuvant radio-immunotherapy. Due to the lack of evidence for an optimal radiotherapy regimen for an "in-situ vaccination" effect three different radiotherapy regimens will be tested.
ETOP 15-19 ABC-lung is an international, multi-centre open-label, randomized phase II trial with two non-comparative parallel arms of atezolizumab plus bevacizumab with carboplatin-paclitaxel (Arm A) or atezolizumab, bevacizumab and pemetrexed (Arm B) in patients with stage IIIB-IV non-squamous non-small cell lung cancer (NSCLC) harbouring EGFR mutations after failure of standard EGFR tyrosine kinase inhibitors (TKIs).
--> This is a substudy of the main ESTxENDS trial (NCT03589989). Micronuclei in buccal epithelial outcomes should be considered secondary outcomes of the main smoking cessation outcome formulated in NCT03589989. Cigarette smoking is the leading cause of preventable death in Switzerland and still more than a quarter of the Swiss population smokes cigarettes. Recently, electronic nicotine delivery systems (ENDS; also called vaporizer, e-cigarette or electronic cigarette) have become popular with smokers who want to stop smoking or reduce their exposure to inhaled chemicals since ENDS use appears to be safer than tobacco smoking. The micronucleus cytologic assay test was originally developed to screen for drug toxicity in bone marrow samples from mammals. The technique identifies micronuclei on smears obtained by oral cavity exfoliation and indicate genomic instability. Buccal MNs may predict cancer risk for the upper aerodigestive tract. The HUman MicroNucleus project on eXfoLiated buccal cells (HUMNXL) found MN counts gradually increased during the progression from normal mucosal to precancerous lesions to carcinoma. MN assessment discriminates between exposure to tobacco smoke in smokers and in non-smokers, and has been tested on a small number of ENDS users. For the main ESTxENDS trial (NCT03589989), cigarette smokers motivated to quit smoking cigarettes will be included. Participants in the intervention group will receive an ENDS and nicotine-containing e-liquids, which they will be allowed to use ad libitum. Additionally, they will receive smoking cessation counseling. Participants in the control group will receive smoking cessation counseling only. All participants will be followed over a 24-month period. Measures of MN frequency will test the potential effect of ENDS use on cancer-related outcomes, in particular incident of mouth-, lung- and kidney- cancers.
