Tranexamic acid to reduce bleeding in adult liver transplant

Official title: A Double-Blind, Randomized, Placebo-Controlled, Multi-Center Trial to Evaluate the Efficacy and Safety of Tranexamic Acid in Adult Liver Transplantation (ESTA Trial)

Run by RenJi Hospital · NCT07157631 · Data updated 2026-11-12

This will test whether giving tranexamic acid during adult liver transplant reduces blood loss in the first 24 hours and does not increase clotting in the first week.

Is this trial a fit for you?

Likely a good fit

Consenting adults (age ≥18) scheduled for allogeneic orthotopic liver transplantation under general anesthesia who do not meet the exclusion criteria.

Probably not a fit

Patients with arterial or venous thrombosis within the prior 3 months, those undergoing re-transplantation, people with known tranexamic acid allergy, or those judged unsuitable by their surgeon or anesthesiologist are unlikely to be eligible or benefit.

What this trial studies

This is a multicenter, randomized, placebo-controlled trial enrolling adults undergoing orthotopic liver transplantation. Participants are randomized to 2.0 g intravenous tranexamic acid at the start of surgery or matching saline placebo. The co-primary hypotheses are that tranexamic acid is superior to placebo for reducing blood loss within 24 hours and non-inferior for a composite of thrombotic events within 7 postoperative days. Secondary endpoints include postoperative drainage volume and blood transfusion requirements within three days. The study plans to randomize 1,546 patients to provide 80% power for the safety (non-inferiority) endpoint and excludes patients with recent thrombosis, re-transplantation, tranexamic acid allergy, or those judged unsuitable by the care team.

Why it matters

Potential benefit: If successful, this could lower perioperative blood loss and reduce the need for transfusions after liver transplant without increasing short-term clotting risk.

How similar studies have gone: Tranexamic acid has reduced bleeding in many types of surgery and smaller liver transplant series have suggested benefit, but large randomized safety data in liver transplantation have been limited.
