Researchers are evaluating the effectiveness of camizestrant compared to standard endocrine therapy in patients with early breast cancer that is estrogen receptor positive (ER+) and human epidermal growth factor receptor 2 negative (HER2-). These patients have an intermediate or high risk of cancer recurrence and have already completed local treatments such as surgery and possibly chemotherapy, alongside at least 2 years and up to 5 years of standard adjuvant endocrine therapy. The study is a Phase III, open-label trial designed to assess outcomes over a long term. Participants will be randomly assigned to receive either camizestrant, an oral selective estrogen receptor degrader, or one of several standard endocrine therapies including tamoxifen, anastrozole, letrozole, or exemestane, administered according to local approved guidelines. The treatment duration for both groups is planned to last 60 months. Eligible patients may have previously used CDK4/6 inhibitors, and the study will specifically include those with intermediate or high risk of recurrence as determined by clinical and biological markers. During the study, participants will be monitored for up to 10 years from the last patient's randomization to evaluate invasive breast cancer-free survival. Additional outcomes include invasive disease-free survival, distant relapse-free survival, overall survival, safety, and clinical outcome assessments. The study involves ongoing assessments of health status, treatment effects, and safety to determine the long-term benefits and risks of camizestrant compared to standard therapies.

Researchers are evaluating the safety and effectiveness of Raludotatug Deruxtecan (R-DXd) in people with platinum-resistant, high-grade ovarian, primary peritoneal, or fallopian tube cancer. This study includes two parts: Phase 2 to find the best dose based on safety and response, and Phase 3 to compare R-DXd with the investigator's choice of chemotherapy. R-DXd is an antibody-drug conjugate that targets CDH6, a protein overexpressed in tumor cells. Participants will receive R-DXd through intravenous infusions. In Phase 2 (Part A), the dose will be optimized, and biopsies will be collected before and during treatment if possible. In Phase 3 (Part B), participants will be randomly assigned to receive either R-DXd or chemotherapy chosen by their doctor, which may include paclitaxel, topotecan, or PLD, all given by IV infusion. The study monitors treatment effects up to 18 months in Phase 2 and up to 26 months in Phase 3. During the study, participants will have regular scans and assessments to measure tumor response and progression-free survival. Researchers will monitor safety and organ function through lab tests and performance status evaluations. Participants must be willing to follow the study visits and procedures, which include biopsy samples in Phase 2 and imaging assessments to evaluate treatment response. The study aims to provide detailed information about how well R-DXd works and its safety in this patient group.

Researchers are evaluating the effects of a medicine called BI 764198 in adults and adolescents aged 12 years and older who have a kidney condition known as focal segmental glomerulosclerosis (FSGS). This Phase 3 study aims to understand whether BI 764198 can improve kidney health in people with primary FSGS or genetic FSGS related to TRPC6 gene variants by comparing changes in urine protein levels over 104 weeks. Participants are randomly assigned to one of two groups: one group takes BI 764198 tablets once daily, and the other group takes placebo tablets that look like the medicine but contain no active drug. All participants continue their usual FSGS treatments during the study, which lasts up to two years. During the study, participants visit the study site approximately every three months. They regularly provide urine samples to monitor kidney function, and doctors check their overall health and note any side effects. The main outcome measured is the change in the 24-hour urine protein-to-creatinine ratio from the start of the study to week 104, helping researchers understand the treatment's impact on kidney disease.

This is a Phase III open-label study to assess if camizestrant improves outcomes compared to standard adjuvant endocrine therapy for patients with ER+/HER2- early breast cancer with intermediate-high or high risk for disease recurrence who completed definitive locoregional therapy (with or without chemotherapy). The planned duration of treatment in either arm of the study is 7 years. Eligible patients must have intermediate-high or high risk of recurrence as defined by specified clinical and biologic criteria. Concurrent use of abemaciclib is permitted in both arms. The primary endpoint of the study is Invasive breast cancer-free survival (IBCFS) and main secondary endpoints include Invasive disease-free survival (IDFS), Distant relapse-free survival (DRFS), Overall survival (OS), Safety and Clinical Outcome Assessments (COAs). Patients will be followed for 10 years from randomization of the last patient.

Researchers are evaluating eye health in patients with breast cancer through a multicenter study. The study aims to assess ophthalmic safety by comparing two groups of patients concurrently to account for age-related changes and worsening of existing eye conditions. The study period for ophthalmic assessments will last approximately 12 months to minimize additional burden on participants. The study includes two parallel cohorts, each with at least 60 participants. Ophthalmic examinations will be conducted at the same time points for both groups. These assessments involve tests such as visual acuity using Snellen units, slit lamp examinations, optical coherence tonometry, and fundus examinations to monitor eye health. Participants will undergo ophthalmic evaluations performed by local ophthalmologists and central readers up to 28 days after the study ends. These evaluations include eye scans and detailed eye health reviews. The study monitors changes in vision and eye structure and safety throughout the 12-month period, ensuring participants' eye health is closely observed.

Researchers are evaluating the safety and performance of remote monitoring functions in pacemakers, specifically the ALIZEA, BOREA, and CELEA devices. These remote features include the Right Atrial Autothreshold (RAAT), Right Ventricular Autothreshold (RVAT), and technical remote alerts. The study focuses on patients with bradycardia who have recently received one of these pacemakers as part of their cardiac care. Participants will undergo implantation or device upgrade with an ALIZEA, BOREA, or CELEA dual chamber pacemaker. The study involves activating remote monitoring functions on these devices to track cardiac pacing performance and system safety. Follow-up visits will occur at 1 to 3 months, 6 months, 12 months, 24 months, and 48 months after inclusion, during which device function and remote monitoring data will be assessed. During each follow-up, either in person or remotely, researchers will measure the pacemaker's performance, including pacing thresholds and remote alerts. Safety will be closely monitored throughout the entire 48-month study period. The main outcomes include changes in right atrial and right ventricular pacing thresholds and documentation of technical remote alerts between 1 and 3 months after device implantation.

Researchers are evaluating the effectiveness and safety of colchicine and non-enteric coated aspirin, alone or combined, to improve heart-related outcomes in high-risk patients with type 2 diabetes. This Phase 3 trial focuses on adults aged 55 to 80 years who have type 2 diabetes and no prior coronary artery disease events but have additional risk factors like long diabetes duration, high blood sugar levels, smoking, or other markers of cardiovascular risk. The study aims to reduce serious cardiovascular events such as heart attacks, strokes, or urgent hospitalizations. Participants are randomly assigned to receive either colchicine 0.5 mg once daily, aspirin 40 mg twice daily, both medications together, or matching placebos. The aspirin is given as a non-enteric-coated tablet twice daily. Those who cannot take aspirin or have certain conditions may still receive colchicine or its placebo. The treatment and follow-up period lasts up to 60 months, during which the occurrence of serious cardiovascular events is closely monitored. During the study, participants will undergo regular assessments including monitoring for cardiovascular events like heart attacks and strokes. Safety labs and clinical evaluations will be conducted to track any side effects or adverse events. The main outcome measured is the time until the first major cardiovascular event occurs. Researchers will also ensure participants adhere to the medication schedule and will follow all patients for up to five years to evaluate long-term safety and effectiveness.

Researchers are investigating whether the medicine vicadrostat, when taken together with empagliflozin, can lower the risk of heart-related problems in adults who have type 2 diabetes, high blood pressure, and cardiovascular disease but no history of heart failure. This study is a Phase III trial that compares the effects of vicadrostat plus empagliflozin to a placebo plus empagliflozin in people with these conditions. Participants are randomly assigned to one of two groups: one group takes vicadrostat and empagliflozin tablets, and the other group takes placebo tablets that look like vicadrostat along with empagliflozin. All participants take one tablet daily for a period ranging from two and a half years up to four years and three months. Throughout the study, participants continue their usual medications for diabetes, high blood pressure, and cardiovascular disease. During up to 51 months of participation, participants visit the study site regularly where doctors collect health information and blood samples. Researchers track when participants experience cardiovascular events such as heart-related deaths or heart failure events. The study also monitors participants’ overall health and any side effects they may experience to assess the safety and effects of the treatments.

Researchers are conducting Enroll-HD, a large, long-term observational study involving individuals affected by Huntington's Disease (HD), those at risk, and control participants. This study combines data from previous registries in Europe, North America, Australasia, and now includes Latin America. It aims to build a comprehensive database of clinical information and biological samples to support research on disease progression, prognosis, and clinical characteristics, as well as to establish clear endpoints for future interventional studies. Enroll-HD collects detailed clinical and genetic information along with blood samples from participants categorized as carriers of the HD gene mutation, controls without the mutation, and family or community controls. The study enrolls participants from over 150 sites in 23 countries and conducts annual assessments without a set end date. Participant groups include those with manifest HD symptoms, pre-manifest carriers, relatives with unknown genotype, and genotype-negative relatives. Participants undergo yearly evaluations including motor, functional, behavioral, and cognitive assessments using standardized scales such as the Unified Huntington's Disease Rating Scale and the Problem Behaviors Assessment-Short. Researchers track changes over an average of one year or longer through this ongoing registry. Data collected supports multiple research efforts and is accessible to qualified researchers worldwide.

Researchers are evaluating the feasibility of the GT Metabolic Solutions Magnet System, GJ Biofragmentable (MagGJ System), to create a side-to-side anastomosis for gastro-ileal or gastro-jejunal diversion in obese adults. This partial diversion of intestinal contents from the stomach to the ileum or jejunum aims to support weight management and metabolic improvements, especially in adults with type 2 diabetes. The study compares this magnetic compression approach to existing surgical procedures like the single anastomosis sleeve ileal (SASI) bypass and one anastomosis gastric bypass (OAGB). The study uses the MagGJ System device to achieve anastomoses by magnetic compression. The procedure involves creating a side-to-side connection between the stomach and the ileum or jejunum to divert intestinal contents. This approach is intended either as a first stage for a two-stage gastric bypass or as a treatment for weight regain after previous sleeve gastrectomy. Participants receive the magnetic device placement and are monitored for the device's passage and anastomosis patency over 30 days. Participants will undergo assessments including magnet placement verification after one day, monitoring natural magnet passage within 30 days, and evaluation of anastomosis openness at day 30. The study includes follow-up visits for safety and effectiveness, with a total participation duration of up to one year. Researchers will observe metabolic outcomes, weight changes, and any adverse events during this period to evaluate the device's feasibility and safety.
