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.
This is a randomized, placebo-controlled, double-blind trial to evaluate the efficacy, tolerability, and safety of ESO-101 in adult patients with active eosinophilic esophagitis (EoE). Patients will be screened at 2 visits (Visit 1 and Visit 2) during which their eligibility will be assessed based on endoscopy-independent criteria (Visit 1) and based on the histologic assessment of esophageal biopsy samples taken during the screening endoscopy (Visit 2). Eligible patients will be randomized 2:1 to once-daily treatment with ESO-101 or placebo and treated for 28 days starting on Day 0. Further clinic visits will be performed at Day 14 (Visit 4) and Day 28 (Visit 5, end of treatment) to assess the efficacy, tolerability, and safety. In addition, a safety follow-up call will be scheduled 2 weeks after the end of treatment (Day 42, Visit 6).
Mescaline (the active substance in Peyote and San Pedro cacti) is a classic and long known serotonergic psychedelic substance (hallucinogen) that is widely used for recreational, spiritual, and/or ethno medical purposes. Despite its long history, modern data on the acute effects of mescaline on human is lacking. Mescaline produces prototypical psychedelic effects, similar as lysergic acid diethylamide (LSD) and psilocybin. The serotonin 2A (5-HT2A) receptor is thought to primarily mediate acute alterations of consciousness induced by LSD and psilocybin. However, the contributory role of the 5-HT2A receptor in mescaline-induced alterations of consciousness is unclear. Using 5-HT2A receptor antagonist ketanserin, the psychedelic experience induced by LSD and psilocybin can be attenuated and shortened. The present study therefore explores the role the 5-HT2A receptor in mescaline-induced altered states of consciousness using escalating doses of mescaline and the 5-HT2A receptor blocker ketanserin administered before a high dose of mescaline. Objective: The present MDR-study will characterize the subjective effects of different doses of mescaline using modern psychometric instruments and examine the contribution of the 5-HT2A receptor in the mescaline-induced alterations of consciousness. Design: Double-blind, placebo-controlled, 6-period cross-over design with six treatment conditions. 1) Placebo (Pla + Pla), 2) 100 mg mescaline (Pla + 100mg mescaline), 3) 200 mg mescaline (Pla + 200mg mescaline), 4) 400 mg mescaline (Pla + 400mg mescaline), 5) 800 mg mescaline (Pla + 800mg mescaline), and 6) 40mg ketanserin and 800mg mescaline (Ket + 800mg mescaline). Participants: 16 healthy participants aged ≥ 25 and ≤ 65 years (8 female, 8 male)
This study is designed as an observational, non-interventional, multicenter, open label, single arm study in patients being treated with Lucentis® for any approved indication included in the local product posology.
The present COVID-19 Virtual Reality (COVVR) clinical study is performed to test the hypothesis that an immersive virtual reality (iVR)-based Digital Therapeutics (DTx), would alleviate dyspnea by improving breathing comfort in patients recovering from COVID-19 pneumonia presenting with persistent dyspnea. We will further evaluate participants' perceived awareness of and agency over their breathing movements. Finally, we will track patients' perceived benefits related to the iVR intervention and the feasibility of using COVVR in the clinic or at home.
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.
Project BECCCS (=Behavior Change in Context to Contain the Spread of COVID-19) aims to optimise and test a behaviour change intervention to promote correct hand hygiene at key times in the short and long term. The study's specific aims are: 1. Optimisation phase: Identify the most effective combination and sequence of three different intervention modules (habit, motivation, social norms), and to assess usability and fidelity measures in order to optimise the intervention 2. Evaluation phase: Test the final intervention against an active control group (basic app content including "Federal Office of Public Health" advice)
