1. What BeneFIX is and what it is used for

BeneFIX is a recombinant DNA-derived injectable product containing coagulation factor IX. The active substance in BeneFIX is nonacog alfa. Patients born with haemophilia B (Christmas disease) lack sufficient coagulation factor IX to control bleeding. BeneFIX works by replacing factor IX in patients with haemophilia B, enabling their blood to clot.
BeneFIX is used for the treatment and prevention of bleeding episodes in patients with haemophilia B (congenital factor IX deficiency) across all age groups.

2. What you should know before taking BeneFIX

Do not take BeneFIX

  • if you are allergic to nonacog alfa or to any of the other ingredients of this medicine (listed in section 6);
  • if you are allergic to hamster proteins.

Warnings and precautions

  • Talk to your doctor or pharmacist before using BeneFIX.

  • Contact your doctor immediately if bleeding does not stop as expected.

  • Allergic reactions are possible. The product may contain traces of hamster proteins (see "Do not take BeneFIX"). Potentially life-threatening anaphylactic/anaphylactoid reactions (severe allergic reactions) have been reported following administration of factor IX-containing products, including BeneFIX. Warning signs of an allergic reaction include difficulty breathing, shortness of breath, swelling, itching, generalized hives, tightness in the chest, trouble breathing, drop in blood pressure, blurred vision, and anaphylaxis (a severe allergic reaction that may cause difficulty swallowing and/or breathing, redness or swelling of the face and/or hands).

  • If allergic or anaphylactic reactions occur, stop administration of BeneFIX immediately and contact your doctor or go to the nearest Emergency Room immediately. In case of severe allergic reactions, alternative therapy should be considered.

  • Neutralizing antibodies (inhibitors) are an uncommon event in previously treated patients with factor IX-containing medicines. However, as with all factor IX medicines, during treatment with BeneFIX you should be closely monitored for the development of factor IX inhibitors.

  • Research has shown an association between the development of factor IX inhibitors and allergic reactions. Therefore, if you experience allergic reactions such as those described above, you should be tested for the presence of an inhibitor. It should be emphasized that patients with factor IX inhibitors may be at increased risk of anaphylaxis if treated again with BeneFIX.

  • Factor IX production in the body is controlled by the factor IX gene. Patients who have specific mutations in their factor IX gene, such as large deletions, may have a higher probability of developing factor IX inhibitors and/or allergic reactions. Therefore, if you know you have such a mutation, your doctor may monitor you closely for signs of allergic reactions, especially during the first administration of BeneFIX.

  • Due to the risk of allergic reactions with factor IX, the first administrations of BeneFIX should be performed under medical supervision in settings where appropriate medical treatment for allergic reactions is available.

  • Even in the absence of factor IX inhibitors, higher doses of BeneFIX may be required than those needed for other plasma-derived factor IX medicines you may have previously received. For this reason, careful monitoring of plasma factor IX activity (which measures your blood's ability to form clots) should be performed to adjust doses as necessary. If bleeding is not controlled with the prescribed dose, consult your doctor.

  • In patients with liver or heart disease or recent surgery, there is an increased risk of blood clotting complications.

  • A kidney disease (nephrotic syndrome) has been reported following high doses of plasma-derived factor IX in patients with hemophilia B who have factor IX inhibitors and a history of allergic reactions.

  • Adequate data from clinical studies on the treatment of previously untreated patients (patients who have never received a prior infusion of factor IX) with BeneFIX are not yet available.

  • For each administration of BeneFIX, it is recommended to record the product name and batch number. You may use one of the removable labels on the vial to document the batch number in your diary or to report any adverse events.

Other medicines and BeneFIX
Inform your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.
Pregnancy and breastfeeding
If you are pregnant, suspect you may be pregnant, are planning a pregnancy, or are breastfeeding, you should take BeneFIX only on the specific advice of your doctor. It is not known whether BeneFIX can cause harm to the fetus when administered to a pregnant woman. Your doctor may advise discontinuing treatment with BeneFIX during pregnancy or breastfeeding.
Consult your doctor or pharmacist before taking this medicine.
Driving and using machines:
BeneFIX does not affect the ability to drive or use machinery.
BeneFIX contains sodium
After reconstitution, BeneFIX contains 0.2 mmol (4.6 mg) of sodium per vial, which is considered essentially "sodium-free". However, depending on your body weight and dose of BeneFIX, you may receive more than one vial. This should be taken into account if you are on a low-sodium diet.

3. How to take BeneFIX

Take this medicine exactly as directed by your doctor or pharmacist. If
you have any doubts, consult your doctor or pharmacist.
Your doctor will determine the dose of BeneFIX you should take. This dose and duration will depend on
your individual needs for factor IX replacement therapy and how quickly your body uses factor IX, parameters which will be monitored regularly.
You may notice a difference in the dose received if switching from a plasma-derived factor IX product to BeneFIX.
Your doctor may decide to adjust the dose of BeneFIX during treatment.

Reconstitution and administration
The procedures below are guidelines for the reconstitution and administration of
BeneFIX. Patients must follow the specific injection procedures indicated by their
doctor.
BeneFIX is administered by intravenous (IV) infusion after reconstitution of the lyophilized powder for injectable preparations with the solvent provided in the pack (a solution of sodium chloride (a salt)) using the pre-filled syringe.
Always wash your hands before performing the following procedures. Aseptic technique (i.e., strict adherence to hygiene standards) must be used during the reconstitution procedure.

Reconstitution:
BeneFIX will be administered by intravenous (IV) infusion after reconstitution with sterile solvent for injectable preparations.

  1. Allow the vial of lyophilized BeneFIX and the pre-filled syringe to reach room temperature.
  2. Remove the plastic cap from the BeneFIX vial to expose the central portion of the rubber stopper.
Two hands hold a medicine vial with a black arrow pointing towards the
  1. Wipe the top of the vial with the provided alcohol swab or another antiseptic solution and allow it to dry. After cleaning, do not touch the rubber stopper with your hands or allow it to come into contact with any surface.
  2. Remove the lid from the plastic packaging of the adapter. Do not remove the adapter from its packaging.
  3. Place the vial on a flat surface. While keeping the adapter in its packaging, place the adapter on top of the vial. Press firmly on the packaging until the adapter snaps onto the top of the vial and the tip of the adapter pierces the vial stopper.

  2. Remove the plastic safety cap from the end of the diluent syringe by breaking it at the perforation. This can be done by bending it up and down until the perforation breaks. Do not touch the inside of the cap or the end of the syringe. The cap may need to be replaced (if the reconstituted BeneFIX is not administered immediately), so temporarily place it aside with the open side up.

  1. The final solution should be inspected visually for particulate matter before administration. The solution should appear clear and colourless.

Note: If more than one vial of BeneFIX is used for infusion, each vial must be
reconstituted as described in the above instructions. The diluent syringe should be removed, leaving the vial adapter in place, and a large luer lock syringe (a device connecting the syringe to the vial) may be used to withdraw the reconstituted contents from each vial.

  1. Ensuring the plunger is still fully inserted, invert the vial. Slowly withdraw all the solution into the syringe.

Note: If the solution is not used immediately, the syringe cap must
be carefully replaced. Do not touch the tip of the syringe or the inside of the
cap.
BeneFIX must be administered immediately or within 3 hours after reconstitution. The reconstituted solution may be stored at room temperature prior to administration.

Administration (Intravenous injection):
BeneFIX should be administered using the pre-filled solvent syringe provided or a single-use sterile plastic luer lock syringe. Additionally, the solution must be drawn from the vial using the vial adapter.
BeneFIX should be administered intravenously over several minutes. Your doctor may adjust the recommended infusion rate to make the infusion more comfortable.
Cases of red blood cell agglutination in the tubing/syringe have been reported during administration of BeneFIX. No adverse events related to these reports have been observed. To reduce the risk of agglutination, it is important to minimize the amount of blood entering the tubing. Blood must not enter the syringe. If red blood cell agglutination occurs in the tubing/syringe, all such materials (tubing, syringe, and BeneFIX solution) must be discarded and administration continued with a new kit.
Since continuous infusion (intravenous drip) of BeneFIX has not been evaluated, BeneFIX must not be mixed with infusion solutions nor administered by intravenous drip.
Dispose of all unused solution, empty vials, used needles, and syringes in a proper container designed for sharps waste—materials that could injure others if not handled appropriately.

If you take more BeneFIX than you should
Contact your doctor immediately if more BeneFIX than recommended has been injected.

If you stop treatment with BeneFIX
Do not stop taking BeneFIX without consulting your doctor.
If you have any questions about the use of this medicine, ask your doctor, pharmacist, or
nurse.

4. Possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them.
Hypersensitivity/allergic reactions
Allergic-type hypersensitivity reactions may occur. Such reactions may include facial or throat swelling, burning and stinging at the infusion site, chills, flushing, itching, headache, hives, low blood pressure, lethargy, nausea, restlessness, tachycardia, chest tightness, tingling, vomiting, wheezing. In some cases, these reactions have progressed to severe anaphylaxis.
Allergic reactions may occur together with the development of factor IX inhibitors (see also "Warnings and precautions").
These reactions are potentially life-threatening. If an allergic/anaphylactic reaction occurs, stop administration of BeneFIX immediately and contact your doctor immediately or go to the nearest Emergency Department. The required treatment depends on the nature and severity of the adverse reaction (see also "Warnings and precautions").
Development of inhibitors
Patients with haemophilia B may develop neutralizing antibodies (inhibitors) against factor IX. If such inhibitors develop, a possible symptom is the increased amount of BeneFIX normally required to control bleeding, or prolonged bleeding after treatment. In such cases, it is recommended to contact a specialized haemophilia centre. Your doctor may wish to monitor you for the development of inhibitors (see "Warnings and precautions").
A kidney disorder has been reported following administration of high doses of plasma-derived factor IX used to induce immune tolerance in patients with haemophilia B who have factor IX inhibitors and a history of allergic reactions (see also "Warnings and precautions").
Thrombotic events
BeneFIX may increase the risk of thrombosis (abnormal blood clots) in your body if you have risk factors for developing blood clots, such as a central venous catheter. Cases of serious blood clotting events have been reported, including life-threatening blood clots in critically ill neonates receiving BeneFIX via continuous infusion through a central venous catheter. Cases of peripheral thrombophlebitis (vein pain and redness) and deep vein thrombosis (blood clots in the limbs) have also been reported; in most of these cases, BeneFIX was administered by continuous infusion, which is not an approved route of administration.
