Tranexamsäure zur Behandlung bei Hirnblutung („Tranexamic acid for intracrebral haemorrhage“ – TICH2)

Data source: BASEC (Imported from 25.04.2024), WHO (Imported from 25.04.2024)

Brief description of trial (Data source: BASEC)

Bei einer Hirnblutung kommt es zu permanenten Schäden im Gehirn, welche eine bleibende (schwere) Behinderung nach sich ziehen können. Mit der Zeit kann die Blutung auch zunehmen, was bedeutet, dass der Grad der Behinderung grösser werden oder dies gar zum Tod führen kann. Zum jetzigen Zeitpunkt gibt es keine medizinische oder chirurgische Behandlung, welche erwiesenermaßen eine Blutung im Gehirn stoppen und zur Verbesserung der Symptome führen kann. In dieser Studie testen wir, ob es möglich ist, Patienten mit einer Hirnblutung innerhalb der ersten Stunden nach Symptombeginn mit einem Medikament – Tranexamsäure – zu behandeln. Wir möchten zeigen, dass eine Behandlung mit diesem Medikament die Chancen zu sterben oder mit einer schweren Behinderung zu leben reduziert. Die Studienmedikation ist eine Substanz, welche dazu führt, dass das Blut verklumpt und eine Blutung gestoppt wird. Dieses Medikament wird nicht in der Routine zur Behandlung einer Hirnblutung eingesetz. Tranexamsäure ist ein etabliertes Medikament, das bereits seit Jahren für andere Erkrankungen eingesetzt wird und dort zuverlässig und schnell Blutungen stoppen kann. Um eine klare Aussage über die Wirkung von Tranexamsäure bei Patienten mit Hirnblutungen machen zu können müssen wir im Rahmen dieser Studie manchen Patienten das Medikament verabreichen und man-chen ein sogenanntes Placebo – eine gleich aussehende Lösung, welche jedoch keine Tranexamsäure enthält.

Health conditions investigated(Data source: BASEC)

Health conditions (Data source: WHO)

Stroke
Circulatory System
Intracerebral haemorrhage

Rare disease (Data source: BASEC)

No

Intervention investigated (e.g. drug, therapy or campaign) (Data source: BASEC)

Die Studienteilnehmer erhalten eine kurze Infusion über 10 Minuten gefolgt von einer Dauerinfusion über 8 Stunden der Studienmedikation (Tranexamsäure oder Placebo).

Interventions (Data source: WHO)

Intravenous tranexamic acid: 1g loading dose given as 100 ml infusion over 10 minutes, followed by another 1g in 250 ml infused over 8 hours. Comparator ? matching placebo (normal saline 0.9%) administered by identical regimen.

Criteria for participation in trial (Data source: BASEC)

a. Intrazerebrale Blutung innerhalb von 8 Stunden nach Symptombeginn
b. Schriftliche Einverständniserkärung durch Patienten oder Angehörigen
c. >18, keine obere Alterslimite

Exclusion criteria (Data source: BASEC)

- Sekundäre intrazerebrale Blutung (Arterio-venöse Malformation, Aneurysma, Tomur, Sinusvenenthrombose)
- Kontraindikationen gegen Tranexamsäure (Tiefe Venenthrombose)
- Schwere vorbestehende Behinderung (modified Rankin Scale >4)
- Glasgow Coma Scale <5
- Lebenserwartung aus anderen Gründen <3 Monate (z.B. Tumor)
- Traumatische intrazerebrale Blutung
- Schwangerschaft/Stillzeit
- Andere Faktoren, welche einen Patienten in den Augen des Investigators als unpassend für die Studie qualifizieren

Inclusion/Exclusion Criteria (Data source: WHO)

Gender: Both
Inclusion criteria: Adult (=18 years, either sex) patients with acute primary intracerebral haemorrhage (PICH) within 8 hours of stroke onset (where stroke onset time is unknown, the time of when last known well will be used)
Exclusion criteria:
1. Patients with intracerebral haemorrhage secondary to anticoagulation, thrombolysis or known underlying structural abnormality such as arterial venous malformation, aneurysm, tumour, venous thrombosis as cause for the intracerebral haemorrhage. Note it is not necessary to exclude an underlying abnormality prior to enrolment, but where a secondary cause of haemorrhage is known, these patients should not be recruited.
2. Patients for whom tranexamic acid is thought to be contraindicated
3. Patients with premorbid dependency (mRS>4)
4. Participation in another drug trial concurrently
5. Prestroke life expectancy <3 months (e.g. advanced metastatic cancer)
6. Coma ? Glasgow coma scale <5

Academic title (Data source: WHO)

Tranexamic acid for IntraCerebral Haemorrhage (TICH-2): a pragmatic phase III prospective double-blind randomised placebo-controlled trial

Type of trial (Data source: WHO)

Interventional

Design of the trial (Data source: WHO)

Pragmatic phase III prospective double-blind randomised placebo-controlled trial (Treatment)

Phase (Data source: WHO)

Phase III

Primary end point (Data source: WHO)

To assess whether tranexamic acid is safe and reduces death or dependency after primary intracerebral haemorrhage (PICH)
Death or dependency (ordinal shift on mRS) at day 90 will be analysed by intention-to-treat using ordinal logistic regression (OLR), with adjustment for minimisation factors. The assumption of proportional odds will be tested using the likelihood ratio test. Comparison of tranexamic acid versus control.

Secundary end point (Data source: WHO)

1. At day 7 (or discharge if sooner), neurological impairment (NIHSS)
2. At day 90, disability (Barthel index), Quality of Life (EuroQoL), cognition, cognition and mood (TICS and ZDS)
3. Safety: death, serious adverse events, thromboembolic events, seizures
4. Costs: length of stay in hospital, re-admission, institutionalisation
5. Radiological efficacy/safety (CT scan): change in haematoma volume from baseline to 24 hours, haematoma location, and new infarction
