Researchers are evaluating whether regular MRI scans can better detect cancer progression in patients on active surveillance for low to medium risk prostate cancer compared to the current standard care recommended by NICE. This study focuses on patients who have chosen active surveillance, as immediate treatment may not improve survival but can cause significant side effects. The trial aims to improve detection of progression over 5 years with fewer biopsies, PSA tests, and clinic visits, potentially reducing anxiety and healthcare costs. Participants will be randomly assigned to either regular MRI scans or the current standard of care. Those in the MRI group will have PSA tests every 6 months and MRI scans annually if they have visible lesions or medium risk cancer. Other patients will have PSA every 6 months and MRI scans in years 1, 3, and 5. Targeted biopsies will be done if MRI shows signs of progression. The standard care group will follow NICE guidelines with regular PSA tests, rectal exams, and biopsies as indicated. During the study, patients will undergo diagnostic MRI scans and biopsies as needed, with monitoring including PSA testing and clinical examinations. The main outcomes measured are biopsy results and cancer staging over 5 years. The study is not blinded and stratifies patients by MRI lesion visibility, cancer grade, and time since diagnosis to ensure balanced groups. The total duration of follow-up is 5 years to assess progression detection and resource use.

Researchers are evaluating the effects of two different default dialysate sodium concentrations, 137 mmol/l and 140 mmol/l, on major cardiovascular events and death in adults receiving maintenance haemodialysis. This pragmatic, cluster-randomised, open-label study takes place in real-world dialysis sites and aims to compare the outcomes associated with these sodium levels over an extended period. The study focuses on patients with end-stage kidney disease undergoing regular haemodialysis treatment. Dialysis sites are randomly assigned to use either a default dialysate sodium concentration of 137 mmol/l or 140 mmol/l for at least 90% of dialysis sessions at that site. All other care practices continue as usual based on local standards. The study plans to recruit sites over 5 to 7 years, with individual follow-up lasting roughly 2 to 5 years. Site participation requires consent, while individual patient consent may be waived or offered an opt-out option. Participants will be monitored for major cardiovascular events and death, with the primary outcome measuring the time until the first such event occurs. Data collection methods are implemented across participating dialysis units, focusing only on in-center or satellite dialysis patients where applicable. The study's duration depends on the occurrence of endpoints, with an average follow-up of about 5 years anticipated per participant.

Researchers are investigating treatments for patients with localized renal cell carcinoma (RCC) who have undergone nephrectomy, focusing on those at high or intermediate risk of the cancer returning. The study evaluates whether durvalumab alone or combined with tremelimumab can improve disease-free survival or overall survival compared to the current standard of care, which is active monitoring. This phase III multi-arm, multi-stage randomized controlled trial includes patients with specific risk scores, and recruitment of intermediate risk patients will be limited based on time and accrual targets. Participants will be randomly assigned to receive either durvalumab alone, the combination of durvalumab and tremelimumab, or active monitoring. The drugs are given via controlled infusion through a pump into a vein. The trial includes a screening phase and treatment period, with careful monitoring of patients' disease status and side effects throughout the study. During the study, participants will undergo clinical and radiological assessments, including post-operative scans and laboratory tests like blood counts and ECGs. Researchers will track disease-free survival and overall survival over several years, including specific time points up to 20.5 years for some comparisons. Participants will also provide tissue and blood samples for future research. Safety and treatment effects will be closely monitored to understand how the therapies impact long-term outcomes.

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.

The trial investigates the role of ixazomib in patients with relapsed multiple myeloma who have previously undergone autologous stem cell transplant (ASCT). This phase III, open-label, randomized, controlled study aims to evaluate whether adding a proteasome inhibitor to the salvage ASCT conditioning improves the depth of response, and to assess the impact of consolidation and maintenance treatments on the durability of response. The study also looks at overall survival, progression time, quality of life, and treatment safety among participants with measurable disease and good performance status. All participants first receive re-induction therapy consisting of 4 to 6 cycles of ixazomib, thalidomide, and dexamethasone (ITD) over 28-day cycles to achieve maximum disease control. Those who reach stable disease or better are randomized to receive either conventional ASCT using melphalan or augmented ASCT combining melphalan with ixazomib. Following this, participants who maintain minimal response or better undergo a second randomization to either receive consolidation therapy with 2 cycles of ITD followed by ixazomib maintenance until disease progression, or no further treatment. During the study, participants will undergo regular assessments including blood tests, disease response evaluations, and monitoring for adverse effects. The primary outcomes measured are overall response rate 100 days after ASCT and progression-free survival up to 10 years. Secondary evaluations include overall survival, time to disease progression, minimal residual disease status at various stages, engraftment kinetics, and quality of life. Follow-up continues with clinic visits every three months until disease progression is observed, enabling long-term monitoring of treatment effects and safety.
