Researchers are evaluating the effects of a medicine called BI 690517 combined with empagliflozin in adults with chronic kidney disease CKD who are at risk of their kidney condition getting worse. The study includes people with or without type 2 diabetes and those who may already be taking medicines like angiotensin converting enzyme inhibitors ACEi, angiotensin receptor blockers ARB, or sodium-glucose cotransporter-2 inhibitors SGLT2i. The goal is to understand if adding BI 690517 can help delay worsening kidney function, hospitalizations due to heart failure, or cardiovascular death. After a run-in period where all participants take empagliflozin and other standard medications, participants are randomly assigned to receive either BI 690517 tablets or placebo tablets once daily alongside empagliflozin. The run-in period confirms that participants are stabilized on empagliflozin before randomization. The treatment phase continues for about three to four years until enough kidney or heart-related events have occurred to compare outcomes between the two groups. During the study, participants visit the study site about five times in the first six months and then every six months thereafter. At these visits, health is regularly checked through blood and urine tests, blood pressure and weight measurements, kidney function monitoring, and collection of any side effect information. The main outcome measured is the time until the first occurrence of kidney disease progression, hospitalization for heart failure, or cardiovascular death.

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.
