NovoSeven® RT (Coagulation Factor VIIa [Recombinant]) does not raise inhibitor titers*

A titer Titer
Concentration or strength of a substance; measures the strength of an inhibitor in a person’s blood. measures the strength of an inhibitor Inhibitor
A substance made by the body that attacks factor so it cannot work as well. For example, a Factor VIII (8) inhibitor would keep Factor VIII from working with other factors and platelets to stop bleeding. . The higher the titer in the blood, the stronger the inhibitor. With NovoSeven® RT, you do not have to worry about raising your titer.

  • NovoSeven® RT was associated with decreases in inhibitor titers when used as the only factor Factor
    A protein in the blood that helps form blood clots.     treatment in a study

People with inhibitors want to keep their titers low. However, factor VIII (8) Factor VIII (8)
One of the 13 clotting-factor proteins that helps form blood clots. and factor IX (9) Factor IX (9)
One of the 13 clotting-factor proteins that helps form blood clots. can raise titers.

No risk of increased titers with NovoSeven® RT
  • NovoSeven® RT is the only bypassing agent Bypassing agent
    A product that treats a bleed without the need for factor VIII (8) or Factor IX (9).     that does not contain any factor VIII or IX, so there is no risk of increased titers with treatment

*Inhibitors to factor VIII or IX.

 

Indications and Usage

NovoSeven® RT (Coagulation Factor VIIa [Recombinant]) is indicated for the treatment of bleeding episodes in hemophilia A or B patients with inhibitors to FVIII or FIX and in patients with acquired hemophilia; prevention of bleeding in surgical interventions or invasive procedures in hemophilia A or B patients with inhibitors to FVIII or FIX and in patients with acquired hemophilia; treatment of bleeding episodes in patients with congenital Factor VII deficiency and prevention of bleeding in surgical interventions or invasive procedures in patients with congenital FVII deficiency.

Important Safety Information

Serious thrombotic side effects are associated with the use of NovoSeven® RT outside of the uses approved by the FDA. These thrombotic side effects are blood clots that form in arteries and veins and can cause harm and may lead to death. Your doctor should discuss the risks and explain the signs and symptoms of thrombotic side effects to you. Your doctor should monitor you for blood clots during treatment with NovoSeven® RT.

Thrombotic side effects following the use of NovoSeven® RT occurred in 0.3% of all bleeds that were treated for FDA-approved uses. The rate of 0.2% was observed in hemophilia patients with inhibitors, and the rate was higher in patients with acquired hemophilia (4%). Thrombotic events (fatal and non-fatal) have been reported following use of NovoSeven® RT for all FDA-approved uses.

Some patients have conditions that may increase the risk of thrombotic side effects. These include clogged arteries, blood clots that form throughout the body instead of at the place of injury (called disseminated intravascular coagulation), a type of blood poisoning called septicemia, and crush injury, which is when a body part is crushed or squeezed between heavy or immobile objects. Also, people taking aPCCs/PCCs (activated or nonactivated prothrombin complex concentrates) at the same time that they are taking NovoSeven® RT may be at increased risk for thrombotic side effects. NovoSeven® RT should be used with caution in patients who have an increased risk for thrombotic side effects. These include, but are not limited to, patients with a history of heart disease, liver disease, patients who have limited movement following surgery, elderly patients, and neonates (babies who are 4 weeks old or younger). In each of these situations, the potential benefit of treatment with NovoSeven® RT should be weighed against the risk of these complications.

Some patients with Factor VII deficiency have developed resistance (antibodies) to Factor VII after treatment with NovoSeven® RT. Factor VII-deficient patients should be monitored for antibody formation before and after administration of NovoSeven® RT.

People who have ever had a bad reaction to NovoSeven® RT or to proteins from mice, hamsters, or “bovines” (such as an ox or cow) should consult their physician prior to using NovoSeven® RT.

The most common side effects in patients treated with NovoSeven® RT are rash, itching, hives, fever, lowered response to treatment, and blood clots in veins.
