How does Praxbind - Idarucizumab work?

The active substance in Praxbind, idarucizumab, is a monoclonal antibody fragment.

What benefit has Praxbind - Idarucizumab shown during the studies?

Praxbind was studied in three main studies involving 141 healthy adult patients who had previously taken dabigatran. In the studies, volunteers received Praxbind or placebo (a dummy treatment) after being treated with Pradaxa for 3.5 The results showed that Praxbind was able to completely neutralize the anticoagulant effect of Pradaxa within 5 minutes of administration. As part of an "ongoing trial," an interim analysis showed similar results in 123 patients who had uncontrolled bleeding or who needed emergency surgery and who were on Pradaxa therapy. Most of the patients in the study were taking Pradaxa to prevent the risk of stroke due to an 'abnormal heart beat' (atrial fibrillation).
