What is rebalancing in hemophilia?

Think of hemostasis as a scale, balanced between 2 sides—procoagulants Procoagulants: proteins that promote clotting. and anticoagulants. Anticoagulants: proteins that promote blood flow.

In hemophilia, there are reduced procoagulants, which causes an imbalance of hemostasis in favor of anticoagulants.

This balance can happen in 1 of 2 ways—either adding procoagulants, or taking away anticoagulants.

Anticoagulants can prevent your blood from clotting inappropriately. There are a number of different types of anticoagulants that naturally exist in the body.

In order to restore hemostasis, rebalancing in hemophilia aims to inhibit certain anticoagulants. Several are being evaluated in ongoing clinical trials, including:

The letters APC in a purple circle to represent activated protein C (APC). activated protein C (APC)
The letters AT in a purple circle to represent antithrombin (AT). antithrombin (AT)
The letters TFPI in a purple circle to represent tissue factor pathway inhibitor (TFPI). tissue factor pathway inhibitor (TFPI)
