Be Part of Research - Trial Details - Tranexamic acid (and Desmopressin) for very early bleeds in the brain

Tranexamic acid (and Desmopressin) for very early bleeds in the brain

Medical Conditions

Hyperacute primary intracerebral haemorrhage (stroke)


This information is provided directly by researchers, and we recognise that it isn't always easy to understand. We are working with researchers to improve the accessibility of this information. In some summaries, you may come across links to external websites. These websites will have more information to help you better understand the study.


Tranexamic acid is a standard treatment in bleeding emergencies such as trauma and childbirth, where it reduces deaths from bleeding. A recent study showed that tranexamic acid given within 8 hours of a bleed on the brain is safe and prevents hematoma (abnormal collection of blood) growth. There was also a small reduction in the number of patients who died within the first 7 days. The study was not large enough to show whether there were effects on long-term disability. Tranexamic acid is cheap (£12) and easy to administer. If it is effective it could make a difference to patients with a bleed on the brain and their families worldwide.
The researchers have worked closely with stroke survivors and their carers to design this study. They told them that increased survival is important, but most people would not want to be alive at the expense of very severe disability, and also that 3 months is too early to measure recovery after stroke 6 months is more appropriate. The researchers discussed emergency consent in detail, and their advisors suggested that most people would be happy with the emergency consent procedure for this study. They also would prefer a blinded study where participants do not know which treatment they receive.

Start dates may differ between countries and research sites. The research team are responsible for keeping the information up-to-date.  

The recruitment start and end dates are as follows:

23 Mar 2022 01 Aug 2027

Patients will be approached about the study in the emergency department as soon as the brain scan confirms bleeding in the brain. The patient will be asked if they want to take part in the study; if they agree, a computer will decide, akin to the toss of a coin, whether they get an injection of tranexamic acid into a vein, or whether they receive saltwater as a placebo. The researchers will use a rapid emergency consent process, in accordance with ethical guidelines. It will be decided by chance which treatment the participants receive and it will not be possible for the doctor or the patient to know if they receive the tranexamic acid or placebo as the treatment packs look identical. It will be one injection, and then normal standard care will be given. The researchers will also contact people at 6 months after their stroke to assess their recovery and quality of life.


Patients most likely to benefit from the treatment - those within 4.5 hours of the start of stroke symptoms (TICH-3), patients taking antiplatelets and within 24 hours of the start of stroke symptoms (DASH-2)

Current key exclusion criteria as of 23/02/2026:

TICH-3 comparison:1. Patient with a known indication for TXA treatment (e.g. traumatic brain injury)2. Patient with contraindication for TXA treatment3. Patient known to be taking therapeutic anticoagulation with warfarin or low molecular weight heparin at the time of enrolment. Patients taking direct oral anticoagulants can be included and are not excluded.4. Massive ICH for which haemostatic treatment seems futile (This would ordinarily be when haematoma volume is estimated as larger than 60ml)5. Severe coma (Glasgow Coma Scale <5)6. Decision was already taken for palliative (end of life) care with the withdrawal of active treatment

DASH-2 comparison:1. Massive ICH for which haemostatic treatment seems futile (This would ordinarily be when haematoma volume is estimated as larger than 60ml (+/-10%))2. Aneurysmal subarachnoid haemorrhage3. Haemorrhage known to be due to transformation of infarction4. Haemorrhage known to be due to a thrombolytic drug,5. Haemorrhage known to be due to venous thrombosis,6. Risk/s of fluid retention associated with desmopressin judged clinically significant by the attending physician (for example patients with pulmonary oedema and/or cardiac failure),7. Significant hypotension (systolic blood pressure <90mmHg),8. Known drug-eluting coronary artery stent in previous three months,9. Known unstable angina or acute coronary syndrome in past month,10. Known allergy to desmopressin,11. Pregnant or breast-feeding,12. Life expectancy less than four hours, or planned for palliative care only13. Glasgow coma scale less than 5.14. Use of substances that are known to induce syndrome of inappropriate ADH section (SIADH), for example, tricyclic antidepressants, selective serotonin re-uptake inhibitors, chlorpromazine and carbamazepine, may cause an additive antidiuretic effect leading to increased rick of water retention and/or hyponatremia.

Tranexamic acid may stop participants from having a further bleed and may help them recover from the stroke but this is not guaranteed. The results of the study will help the treatment of stroke patients in the future. A risk of seizures has been demonstrated with tranexamic acid use in cardiac surgery where high doses of TXA are used. The proposed dose for this study is well below the dose associated with increased seizure risk. A recent traumatic brain injury study demonstrated a reduced death rate in patients given tranexamic acid. A recent study also revealed no increased risk of thromboembolic events (blood clots).
