Researchers are evaluating camizestrant against standard endocrine therapy for patients with ER-positive, HER2-negative early breast cancer who have an intermediate or high risk of disease recurrence. These patients must have completed locoregional therapy and at least 2 to 5 years of standard adjuvant endocrine therapy. The study is a Phase III open-label trial focused on improving outcomes for these patients over a long-term period. Participants are randomly assigned to receive either camizestrant orally or continue with the standard endocrine therapy chosen by their investigator, which may include aromatase inhibitors exemestane, letrozole, anastrozole or tamoxifen. Treatment in each group lasts for 60 months. The study allows prior use of CDK46 inhibitors and includes a follow-up period extending up to 10 years from the last patient randomization. During the study, participants will undergo regular assessments to monitor invasive breast cancer-free survival and other outcomes such as invasive disease-free survival, distant relapse-free survival, overall survival, and safety. Researchers will also evaluate symptoms like joint pain, hot flushes, and vaginal dryness using specific scales, along with quality of life measures and pharmacokinetics. Safety monitoring continues up to 28 days after the last dose, and participants remain under observation for up to 10 years total.

Researchers are evaluating whether skipping additional axillary treatment for patients with early-stage breast cancer who had cancer in their lymph nodes before chemotherapy but show no remaining cancer in those nodes after treatment is as effective as the standard approach. This study focuses on disease-free survival and reducing the risk of lymphoedema five years after treatment. It is a randomized, open, multicenter trial including patients with specific breast cancer stages and confirmed nodal metastases. Participants will all receive standard therapies including HER2-targeted treatment, endocrine therapy, and radiotherapy to the breast or chest wall if needed. They will be randomly assigned to one of two groups one group will not get further axillary treatment such as lymph node removal or radiotherapy, while the other group will receive these axillary treatments according to local guidelines. Follow-up visits will occur annually for at least five years. During the study, participants will undergo assessments to monitor disease-free survival and self-reported lymphoedema using specific questionnaires. Additional evaluations include arm function, quality of life, recurrence rates, survival, and cost-effectiveness analyses. The total study duration is planned for 120 months, including setup, recruitment, follow-up, analysis, and reporting.

Researchers are conducting a multi-centre observational study to better understand giant cell arteritis GCA and polymyalgia rheumatica PMR, conditions mainly affecting people over 50 years old. The study aims to identify genetic factors that influence susceptibility to these diseases to provide new insights into how they develop. It includes both retrospective participants with confirmed diagnoses and prospective participants suspected of having these conditions, with some patients also enrolled in a registry monitoring tocilizumab treatment for relapsing or refractory GCA. The study collects detailed clinical, imaging, and molecular data, including genetic and proteomic analyses, from participants to characterize disease subtypes and impacts. Researchers also assess quality of life through patient-reported outcomes and track long-term prognosis by linking to health records. The study explores environmental factors and co-existing conditions to improve diagnosis, prognosis, and monitoring of disease activity, especially for patients receiving synthetic or biological disease-modifying anti-rheumatic drugs. Participants provide information during baseline assessments, including blood and urine samples for analysis, and complete questionnaires about their symptoms and quality of life. Follow-up occurs through health record review over an average of one year to evaluate diagnosis and disease outcomes. The primary measure is genetic susceptibility, with secondary outcomes focusing on disease characteristics, life impact, diagnosis, and disease activity. The study is sponsored by the University of Leeds and started in 2005, continuing through 2028.

Aortic stenosis AS affects many older adults, with a rising number of people over 65 and 75 years old experiencing moderate to severe disease. This study aims to compare the benefits of early aortic valve replacement AVR versus expectant management in patients with severe asymptomatic AS. It addresses a significant gap, as no randomized controlled trials have yet compared these approaches to determine which leads to better outcomes and cost-effectiveness. Participants will be randomly assigned to either early AVR, where surgery or transcatheter AVR TAVI is planned within six months, or to expectant management, involving regular monitoring according to standard hospital practice. The study will be conducted across multiple centers in the UK, Australia, and New Zealand, with an internal pilot phase to confirm recruitment feasibility. Those in the AVR group may undergo additional tests such as coronary angiography, with further treatment decisions made by their care team. During the study, participants will be followed for a median of 5.5 years, with assessments including cardiovascular events, hospitalizations, quality of life questionnaires, and health economics evaluations. Researchers will measure a combined outcome of cardiovascular death, heart failure hospitalization, and stroke, along with other health and disability measures. The study will use intention-to-treat analysis, ensuring participants are evaluated in their assigned groups regardless of treatment received.

Researchers are studying patients with newly diagnosed stage I, II, and III colorectal cancer CRC to understand how circulating tumor DNA ctDNA in the blood can predict disease relapse. The study evaluates whether using ctDNA to guide adjuvant chemotherapy decisions after surgery is as effective as standard chemotherapy, aiming to reduce unnecessary treatments and side effects. This multi-center, prospective research includes both observational and randomized components to better manage early-stage CRC. The study has two parts Part B focuses on collecting tumor tissue, serial blood samples, and clinical data to detect minimal residual disease MRD using ctDNA after curative surgery. Part C is a randomized trial comparing ctDNA-guided adjuvant chemotherapy versus standard care in patients with high-risk stage II or III CRC. Patients are randomized post-surgery to either standard chemotherapy or a ctDNA-guided approach where those testing negative for ctDNA may receive less chemotherapy. Participants will undergo regular blood sampling and clinical assessments to monitor ctDNA levels and disease status. Researchers will measure outcomes such as 3-year disease-free survival and the relationship between ctDNA detection and treatment response over several years. The study includes follow-up periods of 4 to 8 years to evaluate long-term outcomes and safety. Participants need to consent, adhere to follow-up schedules, and be suitable for chemotherapy if randomized to Part C.
