View of Cerebral Perfusion in Liver Transplantation

Investigator's aim in this study is to compare the more accessible and low-cost Carotid Doppler USG measurements, which are relatively more difficult to access, costly, and have technical disadvantages, and to demonstrate their superiority over each other in the evaluation of cerebral perfusion in liver transplantation surgeries, without any invasive intervention to the patient.

RTX001 Autologous Engineered Macrophages for Liver Cirrhosis

The purpose of this study is to assess the safety and efficacy of RTX001 in patients with end-stage liver disease. This study is the first time RTX001, a macrophage cell therapy engineered to have an anti-inflammatory and anti-fibrotic effect, will be given to humans.

Efficacy and Safety of Tranexamic Acid in Adult Liver Transplantation---ESTA Trial

We propose a multi-center randomized trial to test the primary hypothesis that tranexamic acid is superior to placebo on blood loss in adult orthotopic liver transplantation within the initial 24 hours and that tranexamic acid is non-inferior to placebo for a composite of thrombotic events within the initial 7 postoperative days. Secondarily, we will determine whether tranexamic acid is superior to placebo on total postoperative drainage volume and blood product transfusion within the initial 3 postoperative days. We propose to randomize patients to 2.0 g of tranexamic acid intravenously at the start of surgery or a comparable volume of 0.9% normal saline placebo. Because demonstrating safety will require more patients, our sample size is based on safety. Randomizing 1546 patients will provide 80% power for detecting a non-inferiority margin of 4% with a baseline incidence of 10% for composite thrombotic events within the initial 7 postoperative days.
