Concentration effect curves of the von Willebrand factor (VWF) inhibiting aptamer BT200 on platelet plug formation under high shear stress, ristocetin-induced whole blood aggregation (A), VWF activity and ristocetin cofactor activity (RCo; B) in patients with large artery atherosclerosis stroke or transient ischemic attacks. BT200 was spiked ex vivo into plasma or whole blood. Collagen adenosine diphosphate closure time (CADP-CT) and aggregation were measured by the platelet function analyzer PFA-100 and Multiplate. Data are presented as median values and the interquartile range.
