Fourth Quarter and Recent Corporate Progress

• Reported PB2452 Phase 1 results: In March 2019, full results from the Phase 1 clinical trial of PB2452 were published online in the New England Journal of Medicine in a paper titled, "An Antibody-Based Ticagrelor Reversal Agent in Normal Volunteers" and simultaneously presented in a featured clinical research session at the American College of Cardiology's 68th Annual Scientific Session. Results demonstrated PB2452 provided immediate and sustained reversal of the antiplatelet activity of ticagrelor.
