Massive Transfusion in Children: a Platform RCT of Whole Blood Compared to Component Therapy and Tranexamic Acid to Placebo in Life-threatening Traumatic Bleeding
Philip Spinella
Summary
The MATIC-2 is a multicenter clinical trial enrolling children who are less than 18 years of age with hemorrhagic shock potentially needing significant blood transfusion. The primary objective of the clinical trial is to determine the effectiveness of Low Titer Group O Whole Blood (LTOWB) compared to component therapy (CT), and Tranexamic Acid (TXA) compared to placebo in decreasing 24-hour all-cause mortality in children with traumatic life threatening hemorrhage.
Description
The MATIC-2 trial is a Bayesian, randomized, multicenter, adaptive platform phase III trial. The trial will include injured children with hemorrhagic shock anticipated to require massive blood transfusion, who will be randomized to receive either LTOWB or CT and Tranexamic Acid or placebo. The study investigators hypothesize that the use of LTOWB is non-inferior and/or superior for 24-hour mortality and that LTOWB does not increase the risk of adverse events or outcomes, such as thrombotic events, compared to CT. The investigators also hypothesize that the use of TXA is superior for 24-hour…
