About

People with kidney failure requiring dialysis have a much higher risk of developing cardiovascular (CV) disease compared with the general population. A cardiac cause accounts for 58% of all deaths in patients with end stage kidney disease (ESKD). At the same time, this population has increased risks of clotting as well as bleeding episodes. While aspirin is known to reduce cardiovascular complications in the general population, evidence to support the use of aspirin in people with ESKD receiving dialysis therapy is currently lacking. The ASPIrin to Reduce Event in Dialysis (ASPIRED) trial will test whether aspirin use in dialysis patients safely improves outcomes compared with no aspirin use.

Full description

ASPIRED is an investigator-initiated, multi-center, double-blind, parallel group, event-driven, pragmatic, registry-based randomized controlled trial that will define the value of low dose aspirin (100 mg daily) on cardiovascular events in people with ESKD receiving dialysis.

The study will be conducted using the existing platform of the Chinese peritoneal dialysis (PD) and hemodialysis (HD) Dialysis Registry to screen, recruit and to collect study data as part of patient's routine clinical care during dialysis to improve efficiency and to minimize cost of a clinical trial.

ASPIRED is an event driven trial with an anticipated duration of approximately 5 years.

Randomization will be performed using a web-based system via a pass word protected encrypted website interface.

The study procedure utilizes routine six-monthly clinic visits for study follow-up to increase efficiency and minimize the burden on participants.

The analysis will be based on intention-to-treat principles. An independent Data Safety and Monitoring Board (DSMB) will established to monitor the study for safety and efficacy.
