Plain English Summary
Background and study aims
Major trauma accounts for a significant number of deaths worldwide, and is one of the most frequent causes of death in people under the age of 40. A large number of these deaths are caused by massive blood loss (haemorrhage). Low blood pressure due to blood loss puts extreme pressure on vital organs such as the heart and brain, as they are not receiving enough oxygen. Without correct treatment, this eventually leads to multiple organ failure (MOF).
Development of MOF occurs early (within two days of admission) and is related to an increase in hospital-acquired infections and even death. There is currently no specific treatment which is used to protect against MOF after traumatic haemorrhage however. Artesunate is a drug that has been used for many years as the treatment of choice for severe malaria. It has very few adverse effects and can even be used safely for patients suffering with liver or kidney disease. Laboratory experiments using animals have shown that this drug can actually reduce the risk of organ failure after haemorrhage, as it enhances the protection of organs within the body. This study aims to test the safety and effectiveness of the use of Artesunate in patients with severe trauma and blood loss.
Who can participate?
Adult trauma patients who are actively bleeding as the result of traumatic injury.
What does the study involve?
Due to the urgent/emergency nature of the intervention subjects are recruited within 4 hours of their injury and within 2 hours of admission to the Emergency Department. All participants receive emergency care in accordance with local guidelines for traumatic haemorrhage.
Patients are randomly allocated into one of three study groups, receiving either low dose Artesunate (2.4mg/kg), high dose Artesunate (4.8mg/kg) or placebo (inactive medication). Artesunate is given intravenously (though a vein) because the critical condition of the patients means that it is not an option to take the drug orally. Each participant is given the drug, and then remain in the study for 28 days or until they are discharged from hospital. A scoring system known as the Sequential Organ Failure Score (SOFA) is used throughout this period, in order to track the rate of organ failure in the patients.
What are the possible benefits and risks of participating?
The potential benefits of Artesunate in reducing multiple organ failure outweigh the risk of adverse events associated with the medication. Artesunate has been extensively used in the treatment of both child and adult malaria, including use in critically ill patients. As patients will receive all other clinically indicated treatments, there is no risk of ineffective therapy by administration of the study treatment.

Multiple organ failure following traumatic haemorrhage.
The trial Intervention arm will be split into two stages:
The first stage will be randomised 2:1 low dose intervention (2.4mg/kg) versus placebo.
The second stage will be randomised 2:1 high dose intervention (4.8mg/kg) versus placebo.
As patients will receive all other clinically indicated treatments, there is no risk of ineffective therapy by administration of the trial treatment.
Primary outcome measures
Sequential Organ Failure Score (SOFA) at 48 hours
Secondary outcome measures
1. Maximum Sequential Organ Failure Score (SOFA) over 7 days
2. Total length of hospital stay
3. Total number of days on organ support (as measured by CTCOFR score)
4. Total length of critical care stay
5. Number of ventilator free days
6. Incidence of acute lung injury (as measured by Lung Injury Score)
7. Incidence of acute kidney injury (as measured by RIFLE score)
8. Incidence of infection
9. Mortality (measured at discharge, after 28 days and after 90 days)
