How it works

An innovative approach to hemophilia treatment

HYMPAVZI is designed to help restore balance in the clotting process—independent of factor VIII or IX levels—by targeting TFPI.

Why is balance important?

Balanced scale icon
In people without hemophilia, anticlotting factors and clotting factors work in balance like a scale so the body can clot when needed—without causing too much clotting or too much bleeding.
Unbalanced scale icon
In people with hemophilia, there is a lack of clotting factors, causing the scale to tip toward bleeding.

How does HYMPAVZI help restore balance?

HYMPAVZI uses an innovative approach that may help restore the balance by targeting TFPI to decrease anticlotting activity.
A balanced scale between anticoagulants/bleeding and procoagulants/clotting by inhibiting TFPI
Blocking the activity of TFPI increases the tendency to develop thrombin, which may improve clotting function.

This could potentially help the body prevent or reduce the frequency of bleeding episodes.

HYMPAVZI works without the need to monitor factor levels

By blocking TFPI, HYMPAVZI restores clotting without having to replace factor VIII or IX.

APC=activated protein C; AT=antithrombin; TFPI=tissue factor pathway inhibitor. These do not represent all of the anticlotting and clotting factors in the body.
