Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The overall haemostatic efficacy of Nuwiq in severe haemophilia A patients receiving emicizumab prophylaxis and undergoing major surgery. Efficacy will be assessed at the end of surgery by the surgeon and at the end of the POP (up to 24 hours after the last injection of Nuwiq) by the investigator (haematologist) using a 4 point ordinal haemostatic efficacy scale. Overall haemostatic efficacy will be adjudicated by the Independent Data Monitoring Committee using a predefined algorithm. Timepoint: During surgery and up to 24 hours after last injection of Nuwiq | — |
Secondary
| Measure | Time frame |
|---|---|
| The secondary endpoints of this study are: 1) Assessment of intraoperative haemostatic efficacy of Nuwiq using a 4 point ordinal scale 2) Assessment of postoperative haemostatic efficacy of Nuwiq using a 4 point ordinal scale 3) Number of allogeneic blood products (red blood cells, platelets, & other blood products) transfused. 4) Perioperative FVIII plasma levels immediately before & after Nuwiq injections 5) Perioperative TG immediately before & after Nuwiq injections 6) Perioperative haemostatic efficacy assessed using the 4 point scale recommended by the WFH 7) Incidence of adverse events (AEs) 8) Incidence of thrombotic events 9) Incidence of FVIII inhibitor formation Timepoint: 1) During surgery: From first skin incision to last suture 2) From end of surgery until 24 hours after the last injection of Nuwiq 3) From day of surgery until 24 hours after the last injection of Nuwiq 4) Less than 30 minutes before & less than 30 minutes after Nuwiq injection 5) Less than 30 minutes before & less than 30 minutes after Nuwiq injection 6) Perioperative 7) 8) 9) From start of first Nuwiq injection to 30 days following the surgical procedure | — |
