The science behind ALPROLIX

  • ALPROLIX is a recombinant factor IX protein that is joined, or “fused”, to Fc1
    — Fc is normally found as part of a common protein in your body2
  • Joining factor IX to Fc results in factor with a long half-life3
Watch these videos to learn more about the science behind ALPROLIX
Why does ALPROLIX have a long half-life?
  • Some proteins in circulation, such as clotting factor, are taken out of the bloodstream by cells, where they are broken down2
  • ALPROLIX, however, is thought to use a natural process to delay this breakdown1,2
    — While the exact way this happens is not fully understood, it is believed that this process delays the breakdown of
    ALPROLIX through 3 steps: bind, redirect, and recirculate

Selected Important Safety Information

  • Common side effects of ALPROLIX include headache and abnormal sensation of the mouth
  • Talk to your healthcare provider right away about any side effect that bothers you or does not go away, and if bleeding is not controlled using ALPROLIX

Important Safety Information

Do not use ALPROLIX if you are allergic to ALPROLIX or any of the other ingredients in ALPROLIX.

Tell your healthcare provider if you have or have had any medical problems, take any medicines, including prescription and non-prescription medicines, supplements, or herbal medicines, have any allergies and all your medical conditions, including if you are pregnant or planning to become pregnant, are breastfeeding, or have been told you have inhibitors (antibodies) to Factor IX.

Allergic reactions may occur with ALPROLIX. Call your healthcare provider or get emergency treatment right away if you have any of the following symptoms: difficulty breathing, chest tightness, swelling of the face, rash, or hives.

Your body can also make antibodies called “inhibitors” against ALPROLIX, which may stop ALPROLIX from working properly.

ALPROLIX may increase the risk of formation of abnormal blood clots in your body, especially if you have risk factors for developing blood clots. Call your healthcare provider or seek emergency care if you have symptoms of a possible abnormal blood clot, which may include: chest pain, difficulty breathing, unexpected swelling of an arm or leg with or without pain or tenderness.

Common side effects of ALPROLIX include headache and abnormal sensation of the mouth. These are not all the possible side effects of ALPROLIX. Talk to your healthcare provider right away about any side effect that bothers you or does not go away, and if bleeding is not controlled using ALPROLIX.

You are encouraged to report negative side effects of prescription drugs to the FDA. Visit www.fda.gov/medwatch, or call 1-800-FDA-1088.
