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.

Researchers are evaluating the optimal duration of antibiotic treatment for adults with complicated intra-abdominal infections (cIAI). This Phase 3 trial aims to compare a fixed extended duration of 28 days of antibiotics to the current standard care durations, which typically range from 7 to 18 days. The study will assess clinical outcomes, quality of life, and cost effectiveness over a 180-day follow-up period to determine which approach may better reduce treatment failure and improve patient care while considering antimicrobial resistance concerns. Participants will be randomly assigned to one of two groups: the standard care group, where antibiotic type and duration are determined by their clinician, or the fixed extended-duration group, which receives antibiotics for a set 28-day period. The study includes a total of 1166 adult patients recruited from intensive care units and hospital wards across approximately 30 NHS trust hospitals. The treatment period is followed by monitoring up to 180 days after randomization. During the study, patients or their personal consultees will complete quality of life questionnaires at baseline and at 30, 60, and 180 days post-randomization. They will also provide information about antibiotic use and healthcare resource utilization. Researchers will collect hospital records on admissions, relapses, and further infections. The main outcome measured is treatment failure within 180 days of randomization, with safety and effectiveness assessed throughout the follow-up period.

Researchers are evaluating the use of biparametric MRI (bpMRI) and image-fusion targeted biopsies to detect prostate cancer in men at risk. The study aims to determine if bpMRI can be recommended as an alternative to the longer multiparametric MRI (mpMRI) for identifying clinically significant prostate cancers. It also compares image-fusion targeted biopsy with visual-registration targeted biopsy to see which method better detects significant prostate cancer in patients with suspicious MRI findings. Participants will undergo one of two types of MRI scans: a longer 30-40 minute MRI that uses a contrast dye called gadolinium (commonly used in the NHS), or a shorter MRI without contrast. If the MRI shows suspicious areas, participants may then have a prostate biopsy. Biopsies are performed either by visual registration, where the biopsy needle placement is guided by the operator’s judgment using MRI and ultrasound images, or by image fusion, where MRI images are overlaid on live ultrasound using software to guide the biopsy needle more precisely. During the study, patient scans and biopsy results will be closely monitored and analyzed to measure how many clinically significant cancers are detected within 12 weeks of enrollment. Researchers will collect MRI images, perform biopsies if indicated, and evaluate the biopsy samples under a microscope. The study includes safety monitoring and aims to inform future NHS practices for prostate cancer diagnosis. Male participants aged 18 and older who are referred for prostate MRI due to abnormal exams or elevated PSA levels are eligible to join.

This research aims to evaluate whether lowering blood phosphate levels in people with end-stage kidney disease (ESKD) who are on dialysis can reduce the risk of death or major heart-related events compared to maintaining higher phosphate levels. The study also looks at whether lowering phosphate improves physical health, fatigue, quality of life, patient satisfaction, and itching, as well as whether it is cost-effective. Hyperphosphatemia, or high phosphate in the blood, is common in ESKD and linked to higher death risk, but there is no strong trial evidence that lowering phosphate improves important patient outcomes. Participants will be randomly assigned to one of two groups: an intensive phosphate target group aiming to keep serum phosphate at or below 1.50 mmol/L using phosphate-lowering medications, or a liberal phosphate target group aiming for a higher phosphate range of 2.0 to 2.5 mmol/L. In the liberal group, all phosphate-lowering drugs at baseline will be stopped and only restarted if phosphate rises above 2.5 mmol/L. Medication choice and doses will be based on physicians' and participants' decisions to meet target levels. The trial is multinational and will include 3600 adults on dialysis. During the study, researchers will track major outcomes including cardiovascular death or serious heart and artery events over 5 years. They will also assess physical health, quality of life using the EQ5D-5L questionnaire, fatigue, itching, and overall survival. The study involves monitoring serum phosphate levels and medication use, and measuring cost-effectiveness of the treatment strategies. Participants will be followed closely to understand the safety and impact of the phosphate targets on their health and well-being.

Researchers are evaluating a range of treatments to improve outcomes for adults admitted to intensive care units (ICUs) with severe community-acquired pneumonia (CAP), including cases caused by influenza and COVID-19. This Phase 3 adaptive platform trial, REMAP-CAP, is designed to test multiple treatment strategies simultaneously and adapt over time, allowing new treatments to be added as questions are answered. The trial also serves as a platform to quickly evaluate treatments during respiratory pandemics, such as COVID-19, through a sub-study called REMAP-COVID in the United States. Participants receive various interventions including antibiotics like ceftriaxone, moxifloxacin, or piperacillin-tazobactam, as well as macrolide therapies given for different durations. Other treatments assessed include corticosteroids such as hydrocortisone and dexamethasone, antiviral agents like oseltamivir and remdesivir, immune modulators including tocilizumab and baricitinib, and supportive care strategies such as mechanical ventilation methods. Dosing and duration vary for each treatment, with some interventions now closed. Treatments are administered according to local guidelines and clinical decisions, with some requiring intravenous or enteral routes. Participants are closely monitored with assessments focusing on survival and organ support status in the ICU up to 90 days after enrollment. The main outcomes measured include all-cause mortality by day 90 and the number of days alive without needing organ support in the ICU by day 21. The study collects data continuously to adapt treatment assignments for new participants, aiming to identify the most effective therapies. Follow-up and safety monitoring continue throughout hospitalization and up to 90 days after admission.

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.
