Hereditary Factor X Deficiency Is a Rare Bleeding Disorder that Affects About 1 in a Million People1,2

  • Characterized by insufficient levels of factor X
  • Affects both women and men
  • People with factor X deficiency have a high risk of excess bleeding
  • Often hereditary, as an autosomal recessive disorder

Patients with factor X deficiency may have a high risk of spontaneous, severe, or life-threatening bleeds3

The majority of women with factor X deficiency have a history of heavy menstrual bleeding3

In women of reproductive age with hereditary factor X deficiency:

  • Up to 70% (12/17) have heavy menstrual bleeding3†
  • Risks with pregnancy include miscarriage, uterine bleeding, postpartum hemorrhage, and preterm labor

Patients with factor X deficiency may present with bleeds related to women’s health

Undiagnosed and untreated neonates can be at high risk for severe bleeds

Affected neonates are at risk of experiencing devastating outcomes if hereditary factor X deficiency is not promptly recognized and treated

Symptoms in neonates3,4:

  • Intracranial hemorrhage (ICH)
  • Gastrointestinal (GI) bleeding
  • Bleeding that won’t stop normally from the umbilical stump or post-circumcision
  • Abnormal bruising or bleeding

With Hereditary Factor X Deficiency, ICH and GI Bleeds are Likely to Occur Early in Life3,4

Severity Classification is Unique to Factor X4,6–8

SEVERE

<10 IU/dL
factor X activity

High risk of major spontaneous bleeding

MODERATE

10–40 IU/dL
factor X activity

Minor spontaneous or triggered bleeding risk

MILD

>40–65 IU/dL
factor X activity

Low bleeding risk

  • Decreasing factor X activity has been shown to correlate with increasing bleeding severity7
  • Severity classification as shown is currently widely accepted but differs from that existing at the time of COAGADEX clinical trials, which classified “severe” factor X deficiency activity as <1 IU/dL8
  • The COAGADEX prescribing information recommendation is to monitor trough blood levels of factor X targeting ≥5 IU/dL and adjust dosage to clinical response and trough levels9
  • Analysis of registry data from the European Network of Rare Bleeding Disorders (EN-RBD) suggests maintaining a factor X level of ≥10 IU/dL as the appropriate target for prophylaxis, due to the high risk of major spontaneous bleeding (such as GI or CNS) at <10 IU/dL7,10
  • In the general population, factor X activity ranges from 65–120 IU/dL (reference ranges may vary)8

Treatment Considerations

Clinical guidelines and expert consensus recommend use of plasma-derived factor X concentrate for the treatment of hereditary factor X deficiency4,7,9

“The treatment of factor X deficiency has evolved substantially, from plasma replacement therapy (fresh frozen plasma) to prothrombin complex concentrates (PCCs) to, most recently, the development and licensing approval of a high-purity, plasma-derived, specific single-factor concentrate (pdFX). While patient numbers are small, clinical studies have demonstrated the ability of pdFX therapy to improve hemostasis while limiting the safety concerns associated with earlier treatments such as volume overload (particularly in neonates and young children), anaphylaxis, and thrombosis.”7

Indications and Usage for COAGADEX

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, moderate and severe hereditary factor X deficiency

Contraindication for COAGADEX

COAGADEX is contraindicated in patients who have had life-threatening hypersensitivity reactions to COAGADEX.

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.
