Title: Idarucizumab for Dabigatran reversal 2.0<br/>Author: Hong Kim<br/><a href='http://umem.org/profiles/faculty/526/'>[Click to email author]</a><hr/><p>
Full cohort analysis idarucizumab for dabigatran associated bleeding was recently published in NEJM.</p>
<p>
This study evaluated the laboratory correction of elevated ecarin clotting time or diluted thrombin time induced by dabigatran and time to either cessation of bleeding (Group A: patients with GI bleeding, traumatic bleeding, or ICH) or time to surgery (Group B: patients requiring surgical intervention within 8 hours).</p>
<p>
<strong>Findings</strong></p>
<p>
<strong>Group A (n=301): </strong>Median time to the cessation of bleeding was 2.5 hours in 134 patients.</p>
<p>
HOWEVER:</p>
<ul>
<li style="margin-left:.25in;">
Bleeding cessation could not be determined in 67 patients</li>
<li style="margin-left:.25in;">
Cessation of bleeding could not be assess in 98 patients with ICH</li>
<li style="margin-left:.25in;">
Bleeding stopped spontaneously in 2 patients.</li>
</ul>
<p>
<strong>Group B (n=202):</strong> Median time to intended surgery after infusion of idarucizumab was 1.6 hours.</p>
<ul>
<li style="margin-left:.25in;">
Normal hemostasis in 184 patients (93.4%), mildly abnormal in 10, and moderately abnormal in 3.</li>
<li style="margin-left:.25in;">
Many received PRBC and other blood products during surgery</li>
</ul>
<p>
<strong>Laboratory markers:</strong></p>
<p>
100% reversal of abnormal ecarin clotting time or diluted thrombin time within 4 hours after the administration</p>
<p>
<strong>Mortality</strong></p>
<ul>
<li>
5 Day: Group A: 6.3% vs. Group B: 12.6%</li>
<li>
30 Day: Group A: 13.5% vs. Group B: 12.6%</li>
<li>
90 Day: Group A: 18.8% vs. Group B: 18.9%</li>
</ul>
<p>
</p>
<p>
<strong>Conclusion</strong></p>
<p>
Authors concluded thate idaurcizumab is an "effective" reversal agent for dabigatran.</p>
<p>
Overall, the findings are more promising compared to the interim analysis that was published in 2015.</p>
