Clinical Trial Summary

This is a Phase 1, randomized, double-blind, placebo-controlled, single ascending dose, sequential group study to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of PB2452 (Bentracimab) with and without ticagrelor pretreatment when administered to Chinese healthy male and female subjects.
