SIGNET - a breakthrough study in organ donor research and management Published on: 11 November 2020 Professor John Dark explains more about SIGNET - Statins for Improving orGan outcomE in Transplantation - a new 拢1.3m NIHR funded trial. SIGNET will be one of the largest prospective donor studies in the world, positioned perfectly to coordinate the unique strengths of the UK NHS infrastructure as well as the expertise and facilities available here in 缅北禁地. Many potential organs for donation, particularly the heart and lungs, are damaged in the donor. The process of removal and re-attachment in the recipient can exacerbate this damage. As a result, by no means all the organs offered can be used for transplant. Current estimates suggest that this is the worst for hearts and lungs, where only 20-25% of those offered can be used. A number of additions to the care of the donor could minimise or reverse this damage and these additions might be of real benefit to the recipients of all organs. Professor John Dark SIGNET is designed to explore this issue via analysis of the 'statin' group of drugs. Statins are widely used as cholesterol lowering agents, but may have other benefits many of which revolve around reducing 'inflammation', which is often the root cause of damage to organs in both a donor and a recipient. SIGNET will aim to recruit 2600 adult organ donors, over 4 years, to be randomized after consent for donation and research, to receive Simvastatin 80mg as a single dose The main focus of the study will be to look for an improvement in complications and survival in heart transplant recipients, though the trial also presents an opportunity to look at the potential benefits in all organs. Over 80 sites will be used during the duration of the trial and the UK is ideally placed to explore these options in a national, and scientifically robust way. Expected outcomes The team anticipate the primary outcome will be a composite of mortality, cardiac mechanical support or renal replacement therapy within 30 days following heart transplant. Secondary outcomes are important clinical and safety organ specific transplant outcomes routinely collected by the UK Transplant Registry for all solid organs transplanted from donors in the study. Recruitment will begin in April 2021. Analysis of consent and inclusion will be continuous, with a formal internal pilot phase to the end of year 1. Planned interim analysis will be at two and three years for harm, benefit and futility. Recruitment will run for a total of 48 months, followed by a 12 month follow up period for collection of all organ primary and secondary outcomes. Final analyses and preparation of the final report will be completed by June 2026. Furthermore, SIGNET is another UK first in that it has close links to the newly launched (UKODTRN) The trial team anticipate this collaboration will both support this work and allow them to build on these links for future donor-intervention and organ transplant studies.
