Trial design
CTIS Part I — objectives, methods, condition coding
Main objective
Scope: Safety, Efficacy
To assess the ability of andexanet to achieve effective intraoperative hemostasis when compared to usual care
Secondary objectives 2
- To assess the ability of andexanet to rapidly reverse the anticoagulation effect of FXa inhibitors by reduction of anti FXa activity when compared to usual care at the start of surgery or procedure
- To assess the ability of andexanet to sustainably reverse the anticoagulation effect of FXa inhibitors by reduction of anti FXa activity when compared to usual care at 2 h post start of surgery or procedure
Conditions and MedDRA coding

Study design 3 periods
| # | Title | Allocation | Blinding | Roles blinded | Arms |
|---|---|---|---|---|---|
| 1 | Surgery or Procedure and Study Intervention Period In the andexanet group patients will receive andexanet alfa as IV bolus followed by an infusion. In the usual care group patients will receive treatment based on the Investigator’s discretion, according to regional, local/institutional guidelines or practices.
|
Randomised Controlled | None | Andexanet Treatment Group: In the andexanet group patients will receive andexanet alfa as IV bolus followed by an infusion. Usual Care Treatment Group: In the usual care group patients will receive treatment based on the Investigator’s discretion, according to regional, local/institutional guidelines or practices. |
|
| 2 | Follow-up Period There will be 4 follow-up visits over a duration of approximately 30 days.
|
Not Applicable | None | ||
| 3 | Follow-up Visit for patients with positive anti-andexanet antibody test Patients with a positive anti-andexanet antibody response at Day 30 should have a follow-up anti andexanet antibody test approximately 120 days post-surgery or procedure.
