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 evaluating the use of two types of MRI scans and two biopsy methods to improve prostate cancer diagnosis. The study focuses on whether biparametric MRI bpMRI, which is shorter and does not use contrast dye, can be an alternative to the longer multiparametric MRI mpMRI that uses gadolinium contrast. It also compares image-fusion targeted biopsy, which overlays MRI and ultrasound images during biopsy, with visual-registration targeted biopsy, where biopsy locations are chosen by looking at MRI images separately. Participants first receive either the mpMRI or bpMRI scan. If the MRI suggests cancer, the clinical team decides if a biopsy is needed. Those advised for biopsy undergo either a visual-registration targeted biopsy or an image-fusion targeted biopsy. Both biopsy methods include taking systematic tissue samples to check for cancer. The study does not blind participants or doctors to the MRI or biopsy type used. During the study, participants undergo MRI scans and possibly biopsies based on clinical advice. Researchers collect data on how many clinically significant prostate cancers are detected within 12 weeks of enrollment. They also assess any adverse events related to MRI and biopsy procedures, patient-reported outcomes, and accuracy of cancer detection using different scoring systems. The total duration for outcome assessment is up to 12 weeks after joining the study.

This research aims to evaluate the effects of lowering blood phosphate levels in adults with end-stage kidney disease ESKD who are receiving dialysis. Elevated phosphate levels are common in ESKD and linked to higher risk of death and heart problems, but it is unclear if reducing phosphate improves important patient outcomes. The study will compare intensive lowering of phosphate to a more liberal phosphate target to see if this reduces heart-related deaths and events, improves physical health, and is cost-effective. Participants will be randomly assigned to one of two groups one aiming for a liberal serum phosphate target of 2.0 to 2.5 mmolL, and the other aiming for an intensive target of 1.50 mmolL or lower. Doctors will decide the type and dose of phosphate-lowering medications to help participants reach their assigned phosphate levels, following usual local practices. The study will last up to five years and is conducted internationally with 3600 adults on dialysis. During the study, researchers will monitor participants for major heart-related events and deaths, physical health, fatigue, quality of life, patient satisfaction, and itching. Regular assessments will include measuring time to cardiovascular death or major cardiovascular events and evaluating overall survival and quality of life using the EQ5D-5L tool. The study will also assess cost-effectiveness and continue to observe participants for five years to collect comprehensive data on these outcomes.

Researchers are evaluating treatments for community-acquired pneumonia CAP, especially in patients admitted to intensive care units ICUs. This trial also adapts to study treatments for respiratory pandemics like COVID-19. The goal is to determine which treatment strategies improve outcomes for patients with severe pneumonia, using a flexible, ongoing approach that can test multiple therapies simultaneously and update as new information becomes available. Participants receive different treatment strategies based on random assignment to study groups. Treatments include various antibiotics, steroids, antivirals, immune modulators, anticoagulation methods, and ventilation strategies. Some treatment options have been closed to recruitment, reflecting the trials adaptive nature. The trial includes several domains targeting specific infections such as influenza and COVID-19, with dosing and duration guided by clinical practice and local guidelines. During the study, participants are monitored closely with assessments including survival up to 90 days, days alive without organ support in ICU, ICU and hospital length of stay, ventilator-free days, organ failure-free days, and quality of life up to 6 months. Researchers collect detailed data on patient outcomes, organ support needs, and hospital discharge status. The study runs until February 2028, with ongoing evaluation to improve pneumonia treatment strategies in ICU settings and during respiratory pandemics.

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.
