What this trial studies

This clinical trial investigates the efficacy of nocturnal continuous cyclic peritoneal dialysis (NCPD) compared to continuous ambulatory peritoneal dialysis (CAPD) in non-diabetic patients with end-stage kidney disease. The study is designed as a randomized, open-label, cross-over, multi-center trial involving 124 participants. The primary objective is to assess the adequacy of peritoneal dialysis between the two methods, while secondary objectives include evaluating quality of life factors such as sleep quality and blood pressure. Participants will be monitored for changes in dialysis adequacy over a specified treatment period.

Who should consider this trial

Good fit: Ideal candidates are non-diabetic patients aged 18 to 75 who have been on maintenance peritoneal dialysis for at least one month.

Not a fit: Patients with diabetes mellitus or those with certain acute medical conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into a more effective dialysis method that improves patients' quality of life.

How similar studies have performed: Previous studies have explored similar dialysis methods, but this specific comparison of NCPD and CAPD is novel.
