About PB2452

PB2452 is a novel recombinant human monoclonal antibody antigen-binding fragment, or Fab fragment, designed to reverse the antiplatelet activity of ticagrelor in major bleeding and urgent surgery situations. In clinical and preclinical studies, PB2452 achieved immediate and sustained reversal of ticagrelor’s antiplatelet activity, thereby providing a potential life-saving therapeutic benefit by increasing the safety of ticagrelor, which like all other antiplatelet drugs, has an increased risk of bleeding. There are currently no approved reversal agents for ticagrelor or any other antiplatelet drugs.
