- W4384199265 abstract "Presently, three reversal strategies are available to reverse the anticoagulant activity of the direct oral anticoagulants, each with various limitations or drawbacks. A new reversal agent that addresses some of these limitations or gaps in therapy is in advanced clinical trials. Ciraparantag is a small molecule specifically designed to bind non-covalently by charge-charge interaction to unfractionated heparin and low molecular weight heparin. It shows similar binding characteristics to the direct oral anticoagulants with no off-target binding of selected proteins or commonly used drugs demonstrated to date. Ciraparantag reaches maximum concentration within minutes following intravenous administration with a half-life of 12 – 19 minutes. It is primarily hydrolyzed by serum peptidases into two metabolites, neither of which has substantial activity. Ciraparantag and its metabolites are recovered almost entirely in the urine. In animal models of bleeding a single intravenous dose of ciraparantag given at peak concentrations of an anticoagulant significantly reduces blood loss. In Phase 1/2 clinical trials, ciraparantag restores coagulation in direct oral anticoagulant-treated healthy volunteers with in minutes with a sustained effect over 24 hours. The drug is well tolerated with minor side effects, the most common of which is a flush or sensation of warmth after administration. As a phase 3 trial is in preparation to clinically prove its effectiveness, ciraparantag appears to address many of the short-comings of current reversal strategies." @default.
