Researchers are evaluating whether regular MRI scans can better detect progression in patients on active surveillance for low to medium risk prostate cancer compared to the current standard care defined by NICE. The study aims to see if MRI scans reduce the number of PSA tests, biopsies, and clinic visits over five years while improving cancer progression detection. This trial involves patients who have chosen active surveillance and have a histological diagnosis of localized prostate cancer. Participants are randomly assigned to one of two groups. The standard care group will have PSA tests every 3 months in the first year, then every 6 months with annual rectal exams when clinically indicated, and an MRI at 12 months if not done at diagnosis. Biopsies occur if PSA or rectal exams indicate changes. The intervention group will have PSA tests every 6 months and regular MRI scans annually for patients with visible lesions or medium risk cancer, or in years 1, 3, and 5 for others. Targeted biopsies are performed if MRI PRECISE scores are 4 or higher. The MRI scans are biparametric and do not use gadolinium contrast. Participants will be followed for five years with regular PSA tests, MRI scans, biopsies when indicated, and clinical assessments. Researchers will monitor biopsy and staging results, cost-effectiveness, adverse events related to MRI and biopsies, treatment decisions, compliance, and quality of life using questionnaires on prostate symptoms, anxiety, and general health. The trial is not blinded and aims to provide evidence to improve active surveillance protocols while reducing invasive procedures and healthcare costs.

Researchers are evaluating the impact of two different default dialysate sodium concentrations on major cardiovascular events and death in adults receiving maintenance haemodialysis for end-stage kidney disease. This pragmatic, cluster-randomised, open-label Phase 4 study compares sodium levels of 137 mmoll and 140 mmoll in real-world dialysis settings across multiple sites globally. Dialysis sites will be randomly assigned to use either a default dialysate sodium concentration of 137 mmoll or 140 mmoll for at least 90% of dialysis sessions. Other aspects of patient care will follow standard local practices. Sites must consent to participate, and individual patients will provide waiver or opt-out consent. The study expects to enroll sites over 5 to 7 years, with each participant followed for approximately 2 to 5 years until the study endpoints are reached. Participants will receive dialysis at their assigned sites with the designated sodium concentration. Researchers will monitor the time to first occurrence of major cardiovascular events or death as the primary outcome. Secondary outcomes include other cardiovascular events and individual components of the composite outcomes. Data collection and patient monitoring will continue throughout the study period, estimated to last around five years per participant.

Researchers are evaluating treatment options for patients with localized renal cell carcinoma RCC who have undergone nephrectomy and are at intermediate or high risk of disease recurrence. This phase III randomized controlled platform trial, called RAMPART, aims to assess whether durvalumab alone or combined with tremelimumab can improve disease-free survival or overall survival compared to the current standard care of active monitoring. The study includes patients with Leibovich scores between 3 and 11, focusing on those at intermediate and high risk of relapse after surgery. Participants will be randomly assigned to one of three groups active monitoring for one year, durvalumab monotherapy given as 1500 mg infusions every four weeks for up to 13 cycles, or a combination of durvalumab same dosing with tremelimumab administered twice during the first month. The trial monitors patients over several years to compare outcomes between these groups, including disease-free survival, overall survival, and metastasis-free survival. During the study, participants will undergo clinical and radiological assessments, including post-operative CT scans before randomization and routine follow-ups during treatment and observation. Researchers will collect tissue samples and blood for future research. Safety and health will be closely monitored through laboratory tests, ECGs, and performance status evaluations. The study may last up to 20 years for the longest follow-up on overall survival and other outcomes.

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.

The trial investigates the role of ixazomib in patients with relapsed multiple myeloma who have previously undergone autologous stem cell transplant ASCT. It is a phase III, randomized, controlled, multi-center, open-label study aiming to assess whether adding a proteasome inhibitor to salvage ASCT conditioning improves depth of response and how consolidation and maintenance therapy influence the durability of response. The study also evaluates overall survival, progression-free survival, response rates, minimal residual disease, toxicity, and quality of life. Participants first receive re-induction therapy with 4 to 6 cycles of ixazomib, thalidomide, and dexamethasone ITD, each cycle lasting 28 days. Those achieving at least stable disease are randomly assigned to receive either conventional ASCT using melphalan alone or augmented ASCT combining melphalan with ixazomib. After ASCT, participants with minimal response or better are further randomized to either receive consolidation with 2 cycles of ITD followed by ixazomib maintenance until disease progression or no further treatment. During the study, participants undergo regular assessments including response evaluation 100 days post-ASCT, monitoring of progression-free survival for up to 120 months, and measurement of minimal residual disease at several time points. Safety and toxicity are closely monitored throughout re-induction, post-ASCT, consolidation, and maintenance phases. Quality of life questionnaires are completed at baseline, post-re-induction, post-ASCT, and during follow-up visits up to 24 months. The study plans to register 406 participants, with 284 randomized at the first stage and 248 at the second stage.
