Patients were included if they were at least 18 years of age and had a dose of ticagrelor within three days. In the prespecified interim analysis, platelet inhibition was seen at 5 minutes and minimum inhibition of 50% of the drug was met within four hours of infusion, and was sustained for 24 hours. Inhibition was assessed using the VerifyNow assay and the VASP platelet reactivity index. In patients undergoing surgery, hemostasis was achieved in all, with a 39% rate of transfusion. In bleeding patients, hemostasis was achieved in 78% of patients, with 63% requiring a transfusion. After studying P-selectin and mean platelet volumes, no evidence of platelet rebound activity was found within 72 hours.<\/p>\n<p>When discussing the results of the trial Dr. Bhatt said that he would expect approval of the drug to be limited to \u201cthe conditions that were studied.\u201d He added, \u201cthe drug is not available for commercial or compassionate use at the moment, but the study is very reassuring nonetheless\u201d.\u00a0 <img loading=\"lazy\" loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-6114\" src=\"https:\/\/cardiologynownews.org\/wp-content\/uploads\/2018\/12\/bhatt.jpg\" alt=\"\" width=\"1\" height=\"1\" \/>Dr. Bhatt expects that bentracimab will make significant headway toward approval in U.S and Europe.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Key Points: To date, P2Y-12 inhibitors do not have a commercially approved reversal agent.
