Researchers are evaluating the long-term safety and effectiveness of pembrolizumab (MK-3475) in participants with advanced solid tumors or blood cancers who have previously taken part in other pembrolizumab-based studies. This phase 3 study includes participants who are either currently on treatment or in follow-up from prior parent studies. It aims to understand how well pembrolizumab works over an extended period, up to approximately 10 years, by observing overall survival and safety outcomes. The study has three phases: First Course Phase, Survival Follow-up Phase, and Second Course Phase. Participants who were receiving pembrolizumab, pembrolizumab-based combinations, or lenvatinib in their parent studies will continue treatment in the First Course Phase, completing up to 35 doses every 3 weeks or 17 doses every 6 weeks. Those in the Follow-up Phase will enter the Survival Follow-up Phase without additional treatment but will be monitored. Participants eligible for a Second Course Phase, who have not received other anticancer treatments since their prior pembrolizumab dose and meet health criteria, may receive up to 17 doses every 3 weeks or 8 doses every 6 weeks of pembrolizumab or its combinations. Some may also receive other study drugs such as olaparib, MK-4280, MK-4280A, or pembrolizumab with berahyaluronidase alfa. Participants will be involved in regular treatment visits, safety checks, and long-term monitoring for up to about 10 years to assess overall survival. Researchers will evaluate clinical outcomes, monitor any side effects, and check organ function and physical health status. The study includes detailed eligibility screening, including physical assessments and adherence to contraception requirements for women of childbearing potential. Safety follow-up is ongoing to ensure participant well-being throughout the study.

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.
