Clinical Randomisation of an Antifibrinolytic in Significant Head Injury

Summary

The CRASH-3 trial will provide reliable evidence about the effect of tranexamic acid on mortality and disability in patients with traumatic brain injury. The effect of tranexamic acid on the risk of vascular occlusive events and seizures will also be assessed. Additionally, a nested study will be conducted in a subset of CRASH-3 trial participants. This nested study (CRASH-3 Intracranial Bleeding Sub-Study \[CRASH-3 IBS\]) will examine the effect of tranexamic acid on intracranial haemorrhage and cerebral ischaemia using CT Scans in approximately 1,000 patients randomised into the CRASH-3 trial.
