There were 130 treatment instances of aPCC in 37 patients taking HEMLIBRA. Cases of TMA and TEs were reported when on average a cumulative amount of >100 U/kg/24 hours of aPCC was administered for 24 hours or more to patients receiving HEMLIBRA prophylaxis.5

24-48 | 0 | 6 | 3 1 TE |
>48 | 1 | 5 | 10 3 TMA cases 1 TE |
No events occurred when aPCC was used for <24 hours
Five of the 13 treatment instances reported TMA or TEs when using cumulative amounts of aPCC averaging >100 U/kg/24 hours for ≥24 hours

*Monitoring includes D-dimer, prothrombin fragment F1+2 (if available), platelet count, serum creatinine, LDH, and peripheral blood smear analysis for schistocytes. For patients who require multiple BPA doses, laboratory monitoring should be performed every 24–48 hours thereafter until 24–48 hours following the last BPA dose administered to treat a given bleed.31
