Researchers from Basking Biosciences Inc. presented preclinical data for BB-031, a novel RNA aptamer that binds and inhibits Von Willebrand Factor (VWF). BB-031 (0.5, 1.0 and 5.0 mg/kg) or placebo were administered to a canine model of large vessel occlusion (LVO) stroke at 6 hours post-LVO with an autologous clot.
