What is NovoSeven RT?

NovoSeven RT (coagulation factor VIIa, recombinant) is an injectable, coagulation factor VIIa that may be used to treat bleeding episodes, including managing expected bleeding during surgery, in adults and children with:

NovoSeven RT is also approved to treat bleeding episodes, including managing expected bleeding during surgery, in adults with acquired hemophilia.

NovoSeven RT (coagulation Factor VIIa, recombinant) works by attaching itself (complexing) to tissue factor (TF) which plays a central role in stopping bleeding (hemostasis). The NovoSeven RT-TF complex activates coagulation Factor X to Factor Xa, as well as coagulation Factor IX to Factor IXa. Factor Xa, in complex with other factors, then converts prothrombin to thrombin, which leads to the formation of a hemostatic plug by converting fibrinogen to fibrin and thereby inducing local hemostasis. This process may also occur on the surface of activated platelets.

NovoSeven RT with MixPro is a kit that may be used for self-administration. It comes in a compact package, and contains a:

NovoSeven RT was FDA-approved on July 7, 2014. It is available from a specialty pharmacy distributor, a hemophilia home care agency, or a hemophilia treatment center.

What are the side effects of NovoSeven RT?

NovoSeven RT can cause serious side effects (see warnings below).

The most common side effect of NovoSeven RT is blood clotting events. In clinical trials, these occurred at a rate of 4% of those with acquired hemophilia and 0.2% of bleeding episodes in patients with congenital hemophilia. Other side effects reported in 2% or more of patients were fever, high blood pressure, and a decrease in the levels of plasma fibrinogen.

These are not the only side effects possible with NovoSeven RT. To learn more, talk to your healthcare provider or pharmacist. Tell your healthcare provider about any side effect that bothers you or does not go away. You may report side effects to Novo Nordisk Inc. at 1-877-668-6777 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.

Warnings and serious effects

Do not receive NovoSeven RT if you:

Serious blood clotting events have been reported following NovoSeven RT administration. Patients taking other blood clotting medications or with heart or vascular disease are more at risk. Seek emergency medical help if you develop symptoms of a blood clot such as chest heaviness or pain; pain, swelling, or tenderness in an arm or leg; shortness of breath; severe abdominal pain; limb or facial weakness, difficulty speaking, vision problems, dizziness, or a sudden and severe headache.

Hypersensitivity reactions, including anaphylaxis, can occur with NovoSeven RT. Patients with a known allergy to mouse, hamster, or bovine proteins may be at a higher risk. Call your healthcare provider right away and stop treatment if you get a rash or hives, itching, tightness of the chest or throat, difficulty breathing, light-headedness, dizziness, nausea, or a decrease in blood pressure.

Your body can make antibodies, called inhibitors, against Factor VII, which may stop NovoSeven RT from working properly. Your healthcare provider may need to test your prothrombin time (PT) and factor VII coagulant activity before and after administration of NovoSeven RT and perform an analysis for antibodies if antibody formation may be suspected. Note that certain assays may give different results for different reagents.

Before taking

Before receiving NovoSeven RT, you should tell your healthcare provider if you:

Pregnancy

It is not known if NovoSeven RT can harm your unborn baby. Talk to your healthcare provider about the risks involved with receiving NovoSeven RT if you are pregnant.

Breastfeeding

It is not known if NovoSeven RT passes into your milk and if it can harm your baby. Talk to your healthcare provider about the best way to feed your baby during treatment with NovoSeven RT.

How is NovoSeven RT administered?

NovoSeven RT is administered by an intravenous (into a vein) infusion, directly into the bloodstream. It is usually administered by a healthcare provider initially, but people can be taught how to self-administer it themselves, or a caregiver can be taught how to administer it to a person with hemophilia A or B, congenital Factor VII (FVII) deficiency, or Glanzmann’s thrombasthenia.

Your healthcare provider will tell you how much NovoSeven RT to administer based on your weight, and the condition being treated.

Call your healthcare provider right away if your bleeding does not stop after administering NovoSeven RT.

It is a good idea to record the lot number from the NovoSeven RT label every time you use NovoSeven RT. You can use the peel-off label found on the vial to record the lot number.

The frequency of administration depends on the underlying cause and severity of the bleeding episode but NovoSeven RT is usually administered every 2 to 6 hours.

Do not use NovoSeven RT for a condition for which it is not prescribed or share it with other people, even if they have the same symptoms that you have.

What are the dosage strengths of NovoSeven RT?

NovoSeven RT comes in four different dosage strengths which are printed on the vial label:

Each vial is supplied with a diluent for reconstitution which is a 10 mmol solution of L-histidine in water for injection.

Always check the actual dosage strength printed on the label to make sure you are using the strength prescribed by your healthcare provider.

Rebinyn, Idelvion, tranexamic acid, desmopressin, Hemgenix, Cyklokapron, DDAVP, Humate-P, Hemlibra, Beqvez

What happens if I miss a dose?

If you forget a dose, infuse the missed dose when you discover the mistake. Do not infuse a double dose to make up for a forgotten dose. Proceed with the next infusions as scheduled and speak to your healthcare provider if you have any questions or concerns.

What happens if I overdose?

Always take NovoSeven RT exactly as your healthcare provider has told you. You should check with your healthcare provider if you are not sure. If you inject more NovoSeven RT than recommended, tell your healthcare provider as soon as possible.

What other drugs will affect NovoSeven RT?

Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. NovoSeven RT may affect the way other medicines work. Especially tell your healthcare provider if you take other medications:

NovoSeven RT should not be mixed with other infusion solutions.

NovoSeven RT is safe to use with Hemlibra, which is a monoclonal antibody that works as a “bridge” between other clotting factors to replace missing factor VIII in people with hemophilia A.

Know the medicines you take and the vaccines you receive. Keep a list of them to show your healthcare provider and pharmacist when you get a new medicine. See the prescribing information for a full list of interactions.
