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.
Transcatheter aortic valve implantation (TAVI) serves a growing spectrum of patients with symptomatic severe aortic stenosis (AS). Approximately 80% of surgical aortic valve replacements is performed using a bioprosthesis1. Durability of surgical bioprostheses varies based on the patient's age at the moment of implantation, type and size etc2. TAVI has become the preferred treatment for degenerated aortic bioprostheses in elderly patients3. The median time since index surgical aortic valve replacement (SAVR) and for bioprosthetic valve degeneration is typically 8 - 10 years4-6. TAVI in this setting has proven to have equally favorable results as in native aortic valves7. Balloon expandable8 and self-expanding9 transcatheter heart valves (THV) can be used in a degenerated bioprosthesis and each have specific assets and limitations. TAVI in a failed bioprosthesis can cause coronary obstruction, THV migration, paravalvular leakage and prosthesis patient mismatch. The SAPIEN-3 / Ultra and EVOLUT R/Pro are the 2 most commonly used THV platforms in contemporary clinical practice including treatment of failing surgical aortic bioprostheses. Objective: To compare TAVI with EVOLUT R/Pro vs. SAPIEN-3 / Ultra in terms of device success. Study design: International multi-center randomized study with 1:1 randomization to TAVI with SAPIEN-3 / Ultra or Evolut R/Pro. Study population: 440 patients with a failing surgical aortic bioprosthesis (aortic stenosis with or without aortic regurgitation) and selected for transfemoral TAVI by heart-team consensus. Investigational intervention: Transfemoral TAVI with SAPIEN-3 / Ultra or Evolut R/PRO Main study parameters/endpoints: 1. Primary endpoint is device success at 30 days Defined by - Absence of procedural mortality AND - Correct positioning of a single prosthetic heart valve into the proper anatomical location AND - Intended performance of the prosthetic heart valve (no severe prosthesis- patient mismatch and mean aortic valve gradient < 20 mmHg or peak velocity < 3 m/s, AND no moderate or severe prosthetic valve regurgitation). Severe prosthesis patient mismatch is defined by effective orifice area (EOAi) ≤0.65 cm2/m2 2. Safety endpoint at 1 year defined by the composite of all-cause death, disabling stroke, rehospitalization for heart failure or valve related problems.
Multicenter double-blind placebo controlled phase I dose-escalation trial that will be conducted in France and Switzerland to evaluate different dose levels of CD40.HIVRI.Env (adjuvanted with Hiltonol) alone and in co-administration with DNA-HIV-PT123. A total of 72 eligible healthy participants will be recruited into 6 groups. Within each group, participants will be randomized in a double blind manner to active intervention or placebo in a 5:1 ratio. Enrolment into a given group (other than group "Solo 0.3") will open sequentially depending on the " go-criterion " based on the safety data of the preceding group(s). The primary objective is to assess the safety of three dose levels of CD40.HIVRI.Env (0.3; 1; 3 mg) adjuvanted with Poly-ICLC (Hiltonol®), alone and in combination with DNA-HIV-PT123, administered at weeks 0, 4 and 24 in healthy participants. Secondary objectives are to assess the capacity of poly-ICLC-adjuvanted CD40.HIVRI.Env alone and in combination with DNA-HIV-PT123 to elicit immune responses against HIV (immunogenicity): - Humoral (antibody) responses ; - B-cell responses ; - T-cell responses.
Constant improvements in the areas of diagnostics and treatment lead to an increase of patients surviving an oncological diagnosis ("cancer survivors") thus increasing the cost factor on both society and health care systems. Meta-analysis have shown the effectiveness of multidimensional rehabilitation programs concerning cost-effectiveness and for improving different health parameters. However when submitted to oncological rehabilitation in Switzerland there is no clear definition when to use which specific assessment during the different stages of oncological rehabilitation. This cohort study aims to evaluate and systematically follow-up patients that are assigned for oncological inpatient rehabilitation at the Rehabilitation Center Walenstadtberg. The main purposes are i) to evaluate disease onset of oncological patients during rehabilitation and to identify relationships between mobility and cancer-related fatigue at discharge; ii) to identify predictive factors for everyday functioning and social participation after three months discharge.
Objective: Evaluate the effects of a fast-track (FT) protocol on costs and postoperative recovery. Design: randomized trial Setting: University Hospitals Population: 170 women undergoing total laparoscopic hysterectomy for a benign indication Methods: A FT protocol included the combination of minimally invasive surgery, analgesia optimization, early oral refeeding and rapid mobilization of patients was compared to a usual care protocol. Main outcomes measure: Primary outcome was costs. Secondary outcomes were length of stay, postoperative morbidity and patient satisfaction.
This is a Phase I, single centre, prospective, randomized, alternating panels, ascending doses with interspersed placebo, double-blind, crossover trial. The trial will include 8 volunteers divided into 2 panels (A and B) investigated in alternance, each submitted to 4 investigation periods following a crossover design in double blind, with ascending intravenous doses of MDPK67b and an interspersed placebo. The ascending dose sequence ranges from 2 to 48 mg, with 2-fold increase steps (3 to 4- fold increase steps in each individual volunteer). Three single doses will be administered at a minimum of 2 weeks intervals during the first 3 periods, and finally during the last period 4 repeated doses will be administered at a three days intervals, using either the highest dose of the ascending sequence (i.e. 24 or 48 mg) or the maximal tolerated dose (if it has been exceeded in the ascending sequence of single doses).
Saliva sampling could serve as an alternative non-invasive sample for SARS-CoV-2 diagnosis while rapid antigen testing (RAT) might help to mitigate the shortage of reagents sporadically encountered with RT-PCR. Thus, in the RESTART study the investigators compare antigen and RT-PCR testing methods on nasopharyngeal (NP) swabs and salivary samples. The investigators conducted a prospective observational study among COVID-19 hospitalized patients between 10th December 2020 and 1st February 2021. Paired saliva and NP samples were investigated by RT-PCR (Cobas 6800, Roche-Switzerland) and by two rapid antigen tests: One Step Immunoassay Exdia® COVID-19 Ag (Precision Biosensor, Korea) and Standard Q® COVID-19 Rapid Antigen Test (Roche-Switzerland).
The purpose of this study is to evaluate the diagnostic performance of [18F]CTT1057 as a PET imaging agent for detection and localization of PSMA positive tumors using histopathology as Standard of Truth (SoT). Tissue specimens from both the primary tumor and pelvic lymph nodes dissected during surgery from patients with newly-diagnosed high-risk prostate cancer (PCa) will be used for the histopathology assessments. Approximately 195 participants will be enrolled to ensure that at least 156 participants are evaluable (i.e. have both an evaluable PET/CT scan and histopathology assessment and have not received any prohibited systemic antineoplastic therapy before the completion of PET/CT and surgery), which will be required for the calculation of the co-primary endpoints.
The current study aims at evaluating the diagnostic performance of [18F]CTT1057 as a PET imaging agent for detection and localization of PSMA positivity in patients diagnosed of biochemical recurrence of prostate cancer (PCa), using a composite truth standard. Approximately 190 participants will be enrolled to ensure at least 152 participants are evaluable (i.e. have both an evaluable [18F]CTT1057 PET/CT scan imaging, and at least one evaluable CTS assessment and have not received any prohibited systemic antineoplastic therapy before the completion of PET/CTs and CTS procedures), which will be required for the calculation of the co-primary endpoints.
randomized, controlled single center, single investigator study mainly in colorectal screening population in daily practice with and without artificial intelliegence (AI) named DiscoveryTM from Pentax medical. Patient randomly are allocated to one of four groups: Pentax i10 colonoscopes without any additional device, Pentax i 10 with DiscoveryTM (AI), Pentax i 10 with EndocuffTM and Pentax i10 with EndocuffTM and DiscoveryTM (AI). The different groups are compared in terms of the different parameters: e.g. time of endoscopy, polyps (PDR) and adenoma detected (ADR).
Convalescent plasma therapy has been recognized as safe and plasma transfusion is routinely used in clinical practice. A recent study showed that early administration of convalescent plasma can decrease the risk of complications in specific high-risk population. The aim of the present study is to offer convalescent plasma therapy to immunocompromised patients and older adults in the early phase of a SARS-Cov-2 infection in order to accelerate viral clearance and prevent complication
