About PB2452

PB2452 is a novel, recombinant, human monoclonal antibody antigen-binding fragment, or Fab, designed to reverse the antiplatelet activity of ticagrelor in major bleeding and urgent surgery situations. In a Phase 1 clinical trial, PB2452 demonstrated the potential to bring life-saving therapeutic benefit through immediate and sustained reversal of ticagrelor’s antiplatelet activity, mitigating concerns regarding bleeding risks associated with the use of antiplatelet drugs. The Phase 1 clinical trial of PB2452 in healthy volunteers was published in the New England Journal of Medicinein March 2019.1 In April 2019, PB2452 received Breakthrough Therapy designation from the U.S. Food and Drug Administration (“FDA”). Breakthrough Designation may be granted by FDA when preliminary clinical evidence indicates that the drug may demonstrate substantial improvement over existing therapy. In the first quarter of 2020, PhaseBio plans to initiate a single pivotal Phase 3 clinical trial of PB2452 which will support a Biologics License Application for both major bleeding and surgery indications. There are currently no approved reversal agents for ticagrelor or any other antiplatelet drugs.
