What Is HEMLIBRA®?


HEMLIBRA is a treatment for people with hemophilia A with or without factor VIII inhibitors

HEMLIBRA is a prescription medicine used for routine prophylaxis to prevent or reduce the frequency of bleeding episodes in adults and children, ages newborn and older, with hemophilia A with or without factor VIII inhibitors.

  • Hemophilia A is a bleeding condition people can be born with where a missing or faulty blood clotting factor (factor VIII) prevents blood from clotting normally.
  • HEMLIBRA is a therapeutic antibody that bridges clotting factors to help your blood clot.
  • HEMLIBRA can reduce all bleeds (whether treated or not), and the number of treated bleeding episodes, including joint bleeds, spontaneous bleeds, and target joint bleeds.

HEMLIBRA is not a cure for hemophilia.

What is the most important information I should know about HEMLIBRA?

HEMLIBRA increases the potential for your blood to clot. Carefully follow your healthcare provider’s instructions regarding when to use an on-demand bypassing agent or factor VIII, and the dose and schedule to use for breakthrough bleed treatment. HEMLIBRA may cause serious side effects when used with activated prothrombin complex concentrate (aPCC; FEIBA®), including thrombotic microangiopathy (TMA), and blood clots (thrombotic events). If aPCC (FEIBA®) is needed, talk to your healthcare provider in case you feel you need more than 100 U/kg of aPCC (FEIBA®) total.

How HEMLIBRA is thought to work

HEMLIBRA is thought to bridge activated factor IX (9) and factor X (10) to restore the function of missing activated factor VIII (8) to help your blood clot.

FIXa=activated factor IX (9); FX=factor X (10).

HEMLIBRA offers steady and consistent levels between doses, so there’s no need to adjust dosing based on activities

HEMLIBRA has a half-life of 4 weeks*

Treatment will begin with a loading dose once weekly for 4 weeks to increase the levels of HEMLIBRA in your blood. When the loading dose is complete, you will take a maintenance dose, which helps HEMLIBRA levels in your blood remain steady. Your healthcare provider will decide how often you should take your maintenance dose, which can be once weekly, once every 2 weeks, or once every 4 weeks.

Lower levels of HEMLIBRA in blood were expected in children less than 6 months old.

*After multiple subcutaneous injections, the amount of time estimated for the body to clear half of HEMLIBRA from the blood is 4 weeks.

Before using HEMLIBRA, tell your healthcare provider about all of your medical conditions, including if you:

  • are pregnant or plan to become pregnant. It is not known if HEMLIBRA may harm your unborn baby. Females who are able to become pregnant should use birth control (contraception) during treatment with HEMLIBRA.
  • are breastfeeding or plan to breastfeed. It is not known if HEMLIBRA passes into your breast milk.

Tell your healthcare provider about all the medicines you take, including prescription medicines, over-the-counter medicines, vitamins, or herbal supplements. Keep a list of them to show your healthcare provider and pharmacist when you get a new medicine.

How should I use HEMLIBRA?
See the detailed “Instructions for Use” that comes with your HEMLIBRA for information on how to prepare and inject a dose of HEMLIBRA, and how to properly throw away (dispose of) used needles and syringes.

  • Stop (discontinue) prophylactic use of bypassing agents the day before starting HEMLIBRA prophylaxis.
  • You may continue prophylactic use of factor VIII for the first week of HEMLIBRA prophylaxis.

What should I know about lab monitoring?
HEMLIBRA may interfere with laboratory tests that measure how well your blood is clotting and may cause a false reading. Talk to your healthcare provider about how this may affect your care.

The most common side effects of HEMLIBRA include: redness, tenderness, warmth, or itching at the site of injection; headache; and joint pain.

These are not all of the possible side effects of HEMLIBRA. Speak to your healthcare provider for medical advice about side effects.

Medicines are sometimes prescribed for purposes other than those listed in a Medication Guide. Do not use HEMLIBRA for a condition for which it was not prescribed. Do not give HEMLIBRA to other people, even if they have the same symptoms that you have. It may harm them. You can ask your pharmacist or healthcare provider for information about HEMLIBRA that is written for health professionals.

You may report side effects to the FDA at (800) FDA-1088 or www.fda.gov/medwatch. You may also report side effects to Genentech at (888) 835-2555.
