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 whether avoiding further axillary treatment after neoadjuvant chemotherapy (NACT) is as effective as standard axillary treatment for patients with early stage breast cancer who initially had cancer in the lymph nodes confirmed by needle biopsy but show no residual cancer in the lymph nodes after NACT. The study aims to determine if skipping axillary lymph node dissection (ALND) or axillary radiotherapy (ART) affects disease free survival (DFS) and whether it reduces the risk of lymphoedema five years after treatment. This phase 3, open-label, randomized trial includes patients with T1-3N1M0 breast cancer and confirmed nodal metastases who have undergone sentinel node biopsy removing at least three lymph nodes post-NACT.

This research aims to understand the genetic factors that contribute to the risk of giant cell arteritis (GCA) and polymyalgia rheumatica (PMR). GCA is a serious inflammatory disease affecting blood vessels, mainly in people over 50, which can cause severe complications like vision loss or stroke if untreated. PMR causes pain and stiffness in the limbs with signs of inflammation. The study involves both patients recently suspected of having GCA and those with confirmed diagnoses from the past. It seeks to provide new insights into disease causes and improve diagnosis and treatment approaches. Participants are observed in a multi-center study collecting clinical and genetic data. The study includes both prospective patients with suspected GCA and retrospective patients with confirmed GCA or PMR diagnoses. Some retrospective participants receiving tocilizumab for recurring or difficult-to-treat GCA are also included in a safety monitoring registry. Data collected include clinical features, imaging, tissue and blood samples, and advanced genetic testing. The study also follows patients over time to assess disease impact, quality of life, and long-term outcomes. During the study, participants provide medical information, biological samples, and complete questionnaires about their symptoms and quality of life. Researchers monitor disease activity and treatment effects, especially among those starting certain immune-modifying drugs. The main measurements focus on genetic susceptibility at the study start, with ongoing evaluation of diagnosis, prognosis, and disease progression. The study is designed to improve understanding and management of GCA and PMR over time.

Aortic stenosis (AS) affects a significant portion of the elderly population, with approximately 5% of those over 65 years old and around 3% of those over 75 years having moderate to severe AS. The number of people with AS is increasing rapidly due to an aging population, creating challenges for clinicians in managing mostly elderly patients who are often symptom-free but have severe AS diagnosed incidentally. While symptomatic severe AS requires aortic valve replacement (AVR) or transcatheter aortic valve implantation (TAVI), the best approach for asymptomatic patients remains unclear. This trial aims to compare early AVR or TAVI with standard expectant management in these patients to provide evidence on clinical outcomes and cost-effectiveness. The study is a large, multi-center randomized controlled trial conducted in the UK, Australia, and New Zealand, with plans to expand internationally. It includes two phases: a vanguard phase and a main phase, with an internal pilot to ensure adequate recruitment over two years. Eligible participants with severe asymptomatic AS will be randomly assigned to either early AVR or ongoing surveillance (expectant management). Those in the early AVR group will undergo surgery within about three months, which may include additional procedures like coronary angiography and possible coronary interventions if needed. The trial uses intention-to-treat analysis to compare outcomes between groups. Participants will be closely monitored throughout the study, with evaluations including routine tests and assessments as part of their care. The primary outcome measured is a combination of cardiovascular death and hospitalization for heart failure over a minimum of three years. The study also collaborates with another trial, EVoLVeD, offering participants additional research opportunities. Overall, the study seeks to provide important data on whether early valve replacement before symptoms develop can improve outcomes for people with severe asymptomatic AS.

Researchers are investigating colorectal cancer (CRC) patients with newly diagnosed stage I, II, and III cancers to evaluate whether mutations in circulating tumor DNA (ctDNA) can predict disease relapse earlier than current methods. This study includes two parts: Part B focuses on analyzing tumor tissue, serial blood samples, and clinical data to detect minimal residual disease (MRD) and predict relapse, while Part C is a randomized study comparing ctDNA-guided adjuvant chemotherapy to standard care in high-risk stage II or III CRC patients post-surgery. In Part B, the study collects serial blood samples from patients who have undergone potentially curative surgery to detect and quantify ctDNA, aiming to identify MRD and predict relapse. Part C randomizes patients after surgery into two groups: one receiving standard adjuvant chemotherapy and the other receiving ctDNA-guided chemotherapy, where those testing ctDNA negative may have chemotherapy reduced. The goal is to assess if ctDNA-guided treatment can safely reduce chemotherapy use without compromising disease-free survival. Participants will undergo tumor tissue collection, blood sampling at multiple time points, and clinical assessments over several years. Researchers will monitor ctDNA levels and clinical outcomes, measuring disease-free survival up to 3 to 6 years. Safety and treatment effects will be evaluated, with follow-up visits to track relapse and treatment response. Total participation includes long-term monitoring for relapse prediction and chemotherapy guidance.
