VIDEO: Novel microcapsules show promise in hemophilia A with inhibitory antibodies


 

AT ASH 2016

– Novel microcapsules loaded with factor VIII outperformed systemic factor VIII infusions in models of hemophilia A with inhibitory antibodies, Caroline E. Hansen reported at the annual meeting of the American Society of Hematology.

“This is a completely new paradigm that uses platelet biomechanics to target and deliver a drug,” said Ms. Hansen of Georgia Institute of Technology, Atlanta.

The microcapsules are designed to mechanically shield factor VIII from the immune system. When they reached a modeled site of vascular injury, they contracted and released factor VIII. Initial work showed that this approach triggered significantly more fibrin production in a developing clot than did systemic infusions of factor VIII.

Ms. Hansen had no disclosures. She discussed the findings in a video interview.
