The study will be prospective phase II randomised, double-blind, placebo-controlled, investigator-driven trial in acute intracerebral haemorrhage patients.
The study has 2 arms with 1:1 randomisation to either intravenous Tranexamic acid or placebo and will test the hypothesis that ICH (intracranial haemorrhage) patients treated with intravenous tranexamic acid within 2 hours of symptom onset will have lower rates of haematoma growth than compared to placebo.

Other Name: 0.9%NaCl |
- Relative ICH haematoma growth at 24±3 hours, adjusted for baseline ICH volume (mls) [ Time Frame: 24 hours(plus or minus 3 hours) ]Relative ICH haematoma growth
- ICH growth [ Time Frame: 24 hours (plus or minus 3 hours) ]ICH growth as defined by either 33% or 6ml increase from baseline, adjusted for baseline ICH volume
- Absolute ICH growth (mls) [ Time Frame: 24 hours (plus or minus 3 hours) ]Absolute ICH growth
- Relative ICH growth volume (mls) [ Time Frame: 1 hour after baseline CT ]Relative and absolute ICH growth volume, adjusted for baseline ICH volume
- Major thromboembolic events [ Time Frame: 3 months ]Major thromboembolic events (myocardial infarction, ischaemic stroke, pulmonary embolism) or death
- Intraventricular haematoma growth [ Time Frame: 24 hours (plus or minus 3 hours) ]Absolute intraventricular haematoma (IVH) growth volume adjusted for baseline IVH volume
- Modified Rankin Scale (mRS) [ Time Frame: 3 months ]mRS 0-4 or back to pre-stroke level, or mRS 0-3 or back to pre-stroke level (with lowest mRS score being the better outcome)

Ages Eligible for Study: | 18 Years and older (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- Patients presenting with an acute ICH
- Age ≥18 years
- Treatment can commence within 2 hours of symptom onset (or in patients with unknown time of symptom onset, the time patient was last known to be well)
- Consent can be obtained from participant or person responsible. When emergency treatment procedures have been followed the participant or person responsible will be asked for consent to continue in the study.
Exclusion Criteria:
- Glasgow coma scale (GCS) total score of <8
- Brainstem ICH
- ICH volume >70 ml as measured by the ABC/2 method
- ICH known or suspected by study investigator to be secondary to trauma, aneurysm, vascular malformation, haemorrhagic transformation of ischaemic stroke, cerebral venous thrombosis, thrombolytic therapy, tumour, or infection
- Any history or current evidence suggestive of venous or arterial thrombotic events within the previous 12 months, including clinical, ECG, laboratory, or imaging findings. Clinically silent chance findings of old ischemia are not considered exclusion.
- Hereditary or acquired haemorrhagic diathesis or coagulation factor deficiency.
- Use of heparin, low-molecular weight heparin, GPIIb/IIIa antagonist, or oral anticoagulation (e.g. warfarin, factor Xa inhibitor, thrombin inhibitor) within the previous 14 days, irrespective of laboratory values
- Pregnancy (women of childbearing potential must be tested)
- Planned surgery for ICH within 24 hours
- Concurrent or planned treatment with haemostatic agents (e.g. prothrombin complex concentrate, vitamin K, fresh frozen plasma, or platelet transfusion)
- Participation in any investigational study in the last 30 days
- Known terminal illness or planned withdrawal of care or comfort care measures
- Any condition that, in the judgment of the investigator could impose hazards to the patient if study therapy is initiated or affect the participation of the patient in the study.
