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.
The study is intended to show superiority of AZD9833 in combination with palbociclib (a CDK4/6 inhibitor) versus anastrozole (an aromatase inhibitor) and palbociclib as the initial treatment of patients with hormone receptor-positive (ER-positive), human epidermal growth factor 2-negative (HER2-negative) advanced/metastatic breast cancer. INFORMATION FOR TRIAL PARTICIPANTS In this trial, the researchers will look at how well camizestrant with palbociclib works, compared with anastrozole with palbociclib, in participants with breast cancer that has either spread into other parts of the body at the time of diagnosis, or has come back after at least 2 years of standard endocrine treatment. Participants in this trial will have breast cancer that has ER proteins but does not have overexpression of HER2 protein.
Pulmonary vein isolation (PVI) is an effective treatment for atrial fibrillation (AF). Single shot devices are increasingly used for PVI. Currently, Medtronic Arctic Front cryoballoon is the most frequently used single shot technology and hence is the benchmark for upcoming technologies. A novel cryoballoon technology has recently been introduced (PolarX, Boston Scientific). However, whether PolarX provides effectiveness similar to the standard-of-practice Medtronic Arctic Front cryoballoon is yet to be investigated. Given that PolarX was developed considering the reported limitations and potential failures associated with the Medtronic Arctic Front cryoballoon, it might be even more effective and safe for use in AF ablation procedures. The aim of this trial is to compare the efficacy and safety of the PolarX Cryoballoon (Boston Scientific) and the Arctic Front Cryoballoon (Medtronic) in patients with symptomatic paroxysmal AF undergoing their first PVI. This is an investigator-initiated, multicenter, randomized controlled, open-label trial with blinded endpoint adjudication. Given that the Medtronic Arctic Front Cryoballoon is the standard-of-practice for single shot PVI and the PolarX is the novel technology, this trial has a non-inferiority design. The hypothesis with regards to the primary efficacy endpoint is that the PolarX Cryoballoon (Boston Scientific) shows lower efficacy compared to the Arctic Front Cryoballoon (Medtronic) and that therefore more episodes of first recurrence of any atrial arrhythmia between days 91 and 365 will be observed in patients with symptomatic paroxysmal AF undergoing their first PVI. Hence the alternative hypothesis postulates that the PolarX Cryoballoon is non-inferior to the Arctic Front Cryoballoon. Rejection of the null hypothesis is needed to conclude non-inferiority.
Interventional study using Cannabidiol containing cigarettes as replacement of usual cigarettes Reduction of enforcement measures, improved acute treatment, harm reduction, and improvement of psychotic symptoms
Substudy 02D is part of a larger research study that is testing experimental treatments for melanoma, a type of skin cancer. The larger study is the umbrella study. The goal of substudy 02D is to evaluate the safety and efficacy of investigational treatment arms in programmed cell-death 1 (PD-1) naïve or PD-1 exposed participants with melanoma brain metastasis (MBM) and to identify the investigational agent(s) that, when used in combination, are superior to the current treatment options/historical control available. As of amendment 2 (effective 01DEC2022) enrollment into the treatment arm of pembrolizumab and lenvatinib has been discontinued.
First, the surgical insertion of a ceramic (zirconia) dental implant will be performed in a single-tooth gap according to current state-of-the-art protocols. After a 3-months healing phase, a ceramic tooth replacement (a.k.a. implant crown) will be screw-retained on the implant and will be ready for full chewing, aesthetic and speech function.
The purpose of this study is to determine whether 177Lu-PSMA-617 improves the rPFS or death compared to a change in ARDT in mCRPC participants that were previously treated with an alternate ARDT and not exposed to a taxane-containing regimen in the CRPC or mHSPC settings. Approximately 450 participants will be randomized (225 per treatment group).
This Phase 3 study will evaluate the efficacy of the investigational agent MRTX849 (adagrasib) versus docetaxel in patients who have been previously treated for metastatic NSCLC with a KRAS G12C mutation.
This is a Phase 3 double-blind, placebo-controlled, randomized study designed to investigate whether tafasitamab and lenalidomide as an add-on to rituximab provides improved clinical benefit compared with lenalidomide as an add-on to rituximab in patients with R/R FL Grade 1 to 3a or R/R MZL.
A clinical trial of AAV5-RPGR vector for participants with X-linked retinitis pigmentosa (XLRP)
This is a study for patients with chronic lymphocytic leukemia (CLL) or small lymphocytic leukemia (SLL) who have previously received treatment with at least a BTK inhibitor. The main purpose is to compare LOXO-305 to idelalisib plus rituximab or bendamustine plus rituximab. Participation could last up to four years, and possibly longer, if the disease does not progress.
