Background and study aims
All organs removed from donors have already suffered a degree of damage. As the brain dies (and all of these donors are brain-stem dead) chemicals are released which cause an “inflammation” of the whole body. Measurements of this “inflammation” link to how well the organs function in the recipient after transplant.
Statins are cholesterol-lowering drugs that have benefits across a range of health problems. In particular, statins damp down inflammation in the body and in individual organs. Statins protect the lungs and kidneys in a range of illnesses.
Recently, transplant doctors in Finland linked all this information in an innovative clinical study. Organ donors who were about to donate their heart were randomly allocated to receive a dose of a statin. After the transplant, the recipients who received a heart from a donor who had statins had less heart damage. The numbers were modest, and no survival advantage could be demonstrated. There was a small benefit for lung and liver recipients, but importantly there was no disadvantage in receiving any organ from a donor who had received the drug.
A significant number of hearts and other organs offered for transplant by the donor family are not used; for the heart, this figure is about 75%. The reason for being so selective is that poor function of the donor heart in the recipient is by far the most common cause of death after a transplant. Any step in the donor which might improve the transplanted heart could have a major benefit to the recipient. The same principle applies to all the other organs transplanted.
The aim of this study is to investigate whether giving deceased organ donors a single dose of the drug simvastatin, a very commonly used and safe drug, is beneficial for transplant recipients.
Who can participate?
Adult brain dead organ donors across the UK per year over 4 years
What does the study involve?
Half the donors will receive the drug (in addition to their standard donor care), compared to the other half of donors who will receive standard care only. The drug is given through a tube running into the stomach, already present in 80% of donors, but required to be placed in the other 20%. The drug will be given as soon as the donor family have consented to both organ donation and involvement of their loved one in research.
Half of all the transplant recipients will receive an organ from a donor given the drug. The researchers will follow the results of transplant, focussing on the heart recipients, but for all those receiving these organs, comparing what happens in those who received the drug-treated organs, and those who did not. This is done with data already collected in the national transplant database. No extra data or blood samples will be needed from recipients.
What are the possible benefits and risks of participating?
Unfortunately, there will be no benefit to the donors but there may be a benefit to the person receiving their organs if they are transplanted. People receiving an organ that has been treated with simvastatin may have better outcomes, and it is hoped that this will mean more organs can be transplanted successfully, but it is not known whether this will be the case. Simvastatin is a licensed drug and one of the most prescribed drugs in the UK. There are some risks associated with taking statins for a long time, but this will be a single dose so these risks are not considered a problem at all for this study. With any drug there is a risk of an allergic reaction. This is expected to be very rare as there has only been one case of this reported.

| Scientific title | Statins in organ donor management: an evaluation of the benefits of a single dose of simvastatin given to potential organ donors declared dead by neurological criteria on outcomes in organ recipients |
| Study acronym | SIGNET |
| Study objectives | Does treatment of potential organ donors with simvastatin during protocolised care after diagnosis of death using neurological criteria improve outcomes in patients undergoing transplantation? |
| Ethics approval(s) | Approved 28/06/2021, London - Queen Square Research Ethics Committee (HRA NRES Centre Bristol, 3rd Floor, Block B, Whitefriars, Lewins Mead, Bristol, BS1 2NT, UK; +44 (0)207 104 8061; queensquare.rec@hra.nhs.uk), REC ref: 21/LO/0412 |
| Health condition(s) or problem(s) studied | Organ transplantation |
| Intervention | This is a multi-centre, single-blind prospective, group sequential, randomised controlled trial. Randomisation will be in a 1:1 ratio and will be stratified according to whether the donor was receiving statin therapy at ICU admission. Setting ICUs within Level 1 or 2 donating hospitals: defined as a mean number of donors per year > 6 by NHS Blood and Transplant. Screening Adult organ donors will be identified by the Specialist Nurses in Organ Donation (SNODs). After they have been through the organ donation consent process with the donor family, they will go through the study-specific consent. The SNODs will complete an eligibility checklist which will be countersigned by the prescribing ICU doctor if the patient is randomised to receive the intervention. No screening logs will be completed. Randomisation Following study-specific consent, participants will be randomised using an online randomisation service, called SealedEnvelope, and given a unique Randomisation Number. The treatment allocation will also be provided. Treatment The study treatment is 80 mg simvastatin in addition to protocolised standard care. This will be compared to protocolised standard care alone. If randomised to receive the intervention, this will be prescribed by an ICU doctor and issued from hospital stock. The tablet will be crushed, mixed with 20 ml sterile water (hospital stock) and administered via nasogastric tube. Nasogastric tubes are already in place for 80% of organ donors but if this is not already in place, this will be required. Follow up Although there will be some intervention and donor data collected by the research team onto an eCRF, most of the data from the donors, and all recipient data, is already collected as part of standard care on the UK Transplant Registry. No additional information or samples will be needed from recipients. Safety reporting Serious adverse events will be reported to the REC within 15 days of the clinical team becoming aware. Due to the low-risk intervention and complex patient population, serious adverse events that need reporting will be those assessed by the PI as being related to the study and unexpected. The researchers will also record events that progress to the loss of capacity to donate as a result of the study procedure. |
