What Is COAGADEX?
- COAGADEX is the first and only treatment specifically for hereditary factor X deficiency.
- People with hereditary factor X deficiency don’t have enough factor X in their blood. COAGADEX replaces exactly what’s missing—factor X.
- COAGADEX can be taken in different ways—routinely to help prevent bleeding, with surgery to help prevent bleeding, or as needed if bleeding starts.

Why Choose COAGADEX?
Doctors and patients may choose COAGADEX for many reasons—
Proven Effective
COAGADEX stopped 98% of bleeds in a medical study of adults and older children with hereditary factor X deficiency. Read More
In a medical study of adults and children (12 years of age or older) with hereditary factor X deficiency:
- COAGADEX stopped 98% of bleeds and most bleeds were stopped with just one dose.
- 91% of the adults and children in the study thought COAGADEX was “excellent” in stopping their bleeds.
- In this study, COAGADEX was given as needed for treatment of bleeds and for short-term prevention of bleeding.
High Purity
COAGADEX is high-purity (94%), so you get the factor X you need—without a lot of extra clotting factors. Read More
COAGADEX is the first and only product made specifically for factor X deficiency.
- There are no other therapies approved for the treatment of factor X deficiency. Some patients use treatments that include clotting factors other than factor X. Too many of the other clotting factors can increase the risk for blood clots that may block blood vessels and cause serious side effects. Examples are stroke or a blood clot in the leg.
Rated Excellent
100% of doctors rated COAGADEX as “excellent” in preventing or reducing the number of bleeds in younger children. Read More
In another medical study that included only children up to 11 years of age with hereditary factor X deficiency, COAGADEX was tested to see how well it could reduce or prevent bleeds.
- 100% of doctors who had patients in the study rated COAGADEX as “excellent” in preventing bleeds or reducing the number of bleeds for all children in the study.
Recommended by Experts
COAGADEX is the #1 recommended treatment by medical experts including a national organization for rare bleeding disorders.1–3 Read More
COAGADEX is the only treatment for hereditary factor X deficiency that is recommended by the National Hemophilia Foundation’s Medical and Scientific Advisory Council.
- COAGADEX is also recommended by medical experts in rare bleeding disorders. They like it because it has exactly what is needed—factor X—without a lot of extra clotting factors.
How Does COAGADEX Work?
COAGADEX contains factor X to replace the factor X that is missing in people with hereditary factor X deficiency. The factor X in COAGADEX helps the body form clots to stop bleeding.
- Bleeding begins (like from a cut in the skin)
- The body tries to make a clot to stop the bleeding
- The body needs factor X to help make the clot
WITHOUT COAGADEX
- Without factor X, the body has trouble making a clot
- With no clot, the body keeps bleeding or is very slow to stop it
WITH COAGADEX
- COAGADEX replaces the missing factor X (
)
- COAGADEX helps the body make a clot to stop the bleeding

HEMOPHILIA TREATMENT CENTERS
Some people with factor X deficiency receive care at a hemophilia treatment center (HTC). Visit Savings and Support to learn more about HTCs.
How Is COAGADEX Given?
COAGADEX is given as a liquid through a needle in a vein. This is called an intravenous infusion, or IV.
- At first, COAGADEX is often given in a doctor’s office or infusion center. A nurse will prepare the dose and give the medicine to you.
- In some cases, a nurse may be able to come to your home to give you COAGADEX. If interested, you or your caregiver may be able to learn how to give COAGADEX yourself. A nurse will provide training. It may take a few doses before you feel ready to give COAGADEX without the nurse.
COAGADEX safety
COAGADEX was approved by the United States Food and Drug Administration (FDA) in 2015 as the first and only treatment specifically for hereditary factor X deficiency.
- Some people have side effects from COAGADEX. In clinical trials, the most common side effects of COAGADEX were redness of the skin at the infusion site, pain at the infusion site, tiredness (fatigue), and back pain.
- There are other possible side effects of COAGADEX. Tell your doctor about any side effects that bother you or do not go away.

COAGADEX, a plasma-derived blood coagulation factor X concentrate, is indicated in adults and children with hereditary factor X deficiency for:
- Routine prophylaxis to reduce the frequency of bleeding episodes
- On-demand treatment and control of bleeding episodes
- Perioperative management of bleeding in patients with mild and moderate hereditary factor X deficiency
Limitation of Use
Perioperative management of bleeding in major surgery in patients with severe hereditary factor X deficiency has not been studied.

Important Safety Information for COAGADEX
Allergic type hypersensitivity reactions, including anaphylaxis, are possible with COAGADEX. If symptoms occur, patients should discontinue use of the product immediately, contact their physician, and administer appropriate treatment.
The formation of neutralizing antibodies (inhibitors) to factor X is a possible complication in the management of individuals with factor X deficiency. Carefully monitor patients taking COAGADEX for the development of inhibitors by appropriate clinical observations and laboratory tests.
COAGADEX is made from human plasma and may contain infectious agents, e.g. viruses, the variant Creutzfeldt-Jakob disease (vCJD) agent and, theoretically, the Creutzfeldt-Jakob disease (CJD) agent. No cases of transmission of viral diseases, vCJD or CJD, have been associated with the use of COAGADEX.
In clinical studies, the most common adverse reactions (frequency ≥5% of subjects) with COAGADEX were infusion site erythema, infusion site pain, fatigue and back pain.
