Plain English Summary
Background and study aims
Blunt trauma, also known as blunt force trauma, is a severe physical injury caused by impact of the head or body with a blunt object or surface. One of the most common injuries associated with blunt trauma is damage to the kidneys. The kidneys play a vital role in the body, producing a number of different hormones. One of these hormones, erythropoietin (EPO) stimulates the bone marrow to produce more red blood cells. Previous studies have shown that giving patients a manufactured version of this hormone, known as recombinant human erythropoietin (rhEPO) can help to protect patients with severe injuries from death. The reason why this happens is not known, however further studies have suggested that rhEPO may actually influence the immune system, reducing the risk of infection. The aim of this study is to find out whether treatment with rhEPO can help reduce organ failure rates and improve recovery in adults admitted to intensive care with injuries caused by blunt trauma.
Who can participate?
Adults admitted to intensive care unit (ITU) with blunt trauma with an injury severity score of at least 16.
What does the study involve?
Participants are randomly allocated to one of two groups. Those in the first groups are given an injection under the skin (subcutaneous injection) of rhEPO 1, 8 and 15 days after they are admitted to the ITU. Participants in the second group are given a subcutaneous injection of a dummy (placebo) 1, 8 and 15 days after they are admitted to the ITU. Participants in both groups are monitored for 30 days after they are discharged from ITU in order to establish how many have multiple organ failure, how many survive and the time spent on the ITU ward.
What are the possible benefits and risks of participating?
Participants who receive rhEPO may benefit from a faster recovery as a result of the treatment. Risks of taking part are small however some patients may experience side-effects of rhEPO such as high blood pressure.
Where is the study run from?
Morriston Hospital (UK)
When is the study starting and how long is it expected to run for?
September 2015 to December 2017
Who is funding the study?
Abertawe Bro Morgannwg University Health Board (UK)

Inflammatory response in major injury and recombinant human erythropoietin
The use of recombinant human erythropoietin (rhEPO) reduces organ failure after severe trauma in adults, by effects on the clinical, cellular & biomolecular manifestations of the systemic inflammatory response to injury and the haemopoeitic bone marrow.

Major Trauma (Injury Severity Score 16+)
Participants are randomly allocated to one of two groups.
Intervention group: Participants receive rhEPO (40,000 units) via subcutaneous injection on day 1, 8 and 15 post admission, while the patient remains in ITU.
Control group: Participants receive a subcutaneous injection of a placebo on day 1, 8 and 15 post admission, while the patient remains in ITU.
Participants are followed up for 30 days after discharge from ITU to calculate mortality rates at 30 days.
Primary outcome measure
Multiple organ failaure is monitored using the Denver multiple organ failure score at baseline, day 3 and then daily until discharge from ITU, mortality or 30 days.
Secondary outcome measures
1. Treatment plan (surgery and/or interventional radiology) is recorded at baseline
2. Length of ITU stay is determined at 30 days, time of discharge from ITU or death
3. Critical care support required is measured by mode and duration of mechanical ventilation and inotrope infusion daily throughout ITU stay
4. Length of hospital stay is determined from patient notes at 30 days, discharge or death
5. Thromboembolic vascular events (TVE) rate is determined from reviewing patient notes at 30 days, discharge or death
6. The inflammatory response to injury is measured using the Systemic Inflammatory Response clinical score (SIRS) calculated daily and using cytokine and cellular protein assays at on blood samples taken daily, while on ITU
7. Presence of Persistent Inflammation/Catabolism syndrome (PICS) is calculated from clinical observations and protein assays from day 10, only in those remaining on ITU at that point
8. Leukocyte progenitor proliferation/differentiation in bone marrow aspirates is assessed using flow cytometry and colony forming unit assays obtained on day 2 while on ITU, and subsequently in those requiring pelvic fracture surgery
9. Mitochondrial respiratory function is measured using bioenergetic profile assays on blood obtained daily until while on ITU

Results and Publications
Publication and dissemination plan
The data generated from this study will provide a very high level of evidence relating to the efficacy or otherwise of rhEPO in the major trauma situation. The findings of the study will be presented at scientific meetings and submitted for publication in peer reviewed journals. In addition, a lay-person summary of findings in a post-trial news letter will be made available to all participants and relatives in both a web based format and sent to them if preferred.
