nonacog alpha ( recombinant coagulation factor IX)

1. What BeneFIX is and what it is used for

BeneFIX is an injectable product containing coagulation factor IX produced by recombinant DNA technology. The active substance in BeneFIX is nonacog alfa. People born with haemophilia B (Christmas disease) do not have enough coagulation factor IX to control bleeding. BeneFIX works by replacing factor IX in hemophilia B patients to allow their blood to coagulate.

BeneFIX is used for treating and preventing bleeding in patients with haemophilia B ( congenital haemorrhagic disease I coagulation factor IX) in all age groups.

2. What you need to know before using BeneFIX

Do not use BeneFIX

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

Warnings and cautions

  • Talk to your doctor or pharmacist before using BeneFIX.
  • Contact your doctor immediately if the bleeding does not stop as expected.
  • Allergic reactions are possible. The product may contain traces of hamster proteins (see “Do not use BeneFIX”). Potentially life-threatening anaphylactic reactions (severe allergic reaction ) have occurred with factor IX products, including BeneFIX. Early signs of allergic reactions include difficulty breathing, shortness of breath, swelling, hives that may be widespread throughout the body, itching , chest tightness, wheezing, low blood pressure , blurred vision and anaphylaxis (severe allergic reaction that may cause difficulty swallowing and / or or breathing, redness or swelling of the face and / or hands).
  • If allergic or anaphylactic reactions occur, discontinue injection of BeneFIX immediately and consult a physician , or seek emergency medical attention immediately . If severe allergic reactions occur, alternative therapy should be considered.
  • It is less common for previously treated patients receiving factor IX products to develop neutralizing antibodies (inhibitors). However, during treatment with BeneFIX, you should be closely monitored to check if factor IX inhibitors have been developed. The same applies to treatment with all products containing factor IX.
  • In the literature, it has been reported that there is an association between the presence of factor IX inhibitors and allergic reactions. Therefore, if you get allergic reactions such as those described above, you should be investigated for the presence of inhibitors. It should be noted that patients taking factor IX inhibitors may be at higher risk of anaphylaxis during additional BeneFIX treatment sessions.
  • The body’s production of factor IX is regulated by the factor IX gene. Patients who have specific mutations on the factor IX gene, such as larger deletion mutations, may be more likely to develop factor IX inhibitors and / or have allergic reactions. If you are known to have such a mutation, your doctor may monitor you extra closely for signs of an allergic reaction, especially when you start treatment with BeneFIX for the first time.
  • Due to the risk of allergic reactions to factor IX, your first injections of BeneFIX should be given under medical supervision so that appropriate medical treatment for allergic reactions is available.
  • Even in the absence of inhibitors, a higher dose of BeneFIX may be needed compared to other plasma IX products that you may have taken before. Careful monitoring of factor IX plasma activity (which measures your blood’s ability to coagulate) must therefore be performed to adjust dose one. If the bleeding is not under control after the recommended dose , consult your doctor.
  • If you have liver or heart disease or if you have recently undergone surgical treatment, there is an increased risk of clot formation (coagulation complications).
  • Renal impairment ( nephrotic syndrome ) has been reported at high doses of factor IX produced by blood plasma in haemophilia B patients with factor IX inhibitors who have previously experienced allergic reactions.
  • Sufficient data have not been obtained from clinical trials regarding BeneFIX treatment in patients who have not previously received any treatment (patients who have never received a factor IX infusion before ).
  • It is recommended that you note the name and batch number of the product each time you use BeneFIX. You can use one of the removable labels on the bottle to document the batch number in your diary or to report side effects .

Other medicines and BeneFIX

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.

Pregnancy, breastfeeding, and fertility

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, you should only take BeneFIX as prescribed by your doctor. It is not known whether BeneFIX can cause harm to an unborn baby when taken by pregnant women. Your doctor may advise you to stop taking BeneFIX if you are breast-feeding or pregnant.

Ask your doctor or pharmacist for advice before taking this medicine.

Driving and using machines

BeneFIX has no effect on the ability to drive or use machines.

BeneFIX contains sodium

After preparation BeneFIX contains 0.2 mmol (4.6 mg) of sodium per vial , ie essentially “sodium-free”. However, depending on your body weight and your dose ofBeneFIX, you may receive several vials. This should be considered if you have been prescribed a low-salt diet.

3. How to use BeneFIX

Always use this medicine exactly as your doctor or pharmacist has told you. Ask your doctor or pharmacist if you are unsure.

Your doctor will decide on the dose of one of BeneFIX that you should take. The doseand duration of treatment depends on your individual need for factor IX replacement therapy and how quickly your body uses up factor IX, which will be checked regularly. You may notice a difference in the dose you receive if you switch from a plasma factor IX product to BeneFIX.

Your doctor may change the dose of BeneFIX you receive during treatment.

Preparation and administration

The instructions below are advice for the preparation and administration of BeneFIX. Follow your doctor’s instructions for venipuncture.

BeneFIX is given by intravenous (IV) infusion after reconstitution of the powder for solution for injection with the supplied diluent (sodium chloride (saline) solution) in the pre-filled syringe.

Always wash your hands before doing the following. Aseptic technique (meaning clean and germ-free) should be used during reconstitution .

Preparation :

BeneFIX is given by intravenous (IV) infusion after reconstitution with sterile diluent .

1. Allow the bottle of freeze-dried BeneFIX and the pre-filled syringe to reach room temperature.

2. Remove the plastic cap from the BeneFIX bottle so that the middle part of the rubber stopper is visible.

The picture describes how the plastic cap is removed

3. Clean the stopper with the supplied compress one with alcohol or use another antiseptic solution and let it dry. Do not touch the rubber stopper with your hand after cleaning and do not allow the stopper to come into contact with any surface.

4. Remove the cap from the bottle adapter’s clear plastic package. Do not remove the adapter from the package.

5. Place the bottle on a flat surface. While holding the adapter package, place the adapter over the bottle. Press firmly down on the package until the adapter clicks into place at the top of the bottle and the adapter needle passes through the rubber stopper of the bottle.

The picture describes how the adapter is put on the bottle

6. Lift the package off the adapter and discard the package.

The picture describes how to remove the packaging from the adapter

7. Attach the piston rod to the syringe with diluent by pressing and screwing firmly.

8. Break the plastic cap from the syringe with diluent by breaking the perforation on the cap. This is done by bending up and down until the perforation is broken. Do not touch the inside of the cap or the top of the syringe. The lid may need to be used again (unless the reconstituted BeneFIX is administered immediately), so set it aside by placing it on top.

The picture describes how the plastic lid is broken from the syringe

9. Place the bottle on a flat surface. Attach the diluent with the diluent to the bottle adapter by placing the top of the syringe in the adapter opening while pressing firmly and screwing the syringe clockwise until it has stabilized in place.

The picture describes how the syringe is attached to the bottle

10. Slowly push in the plunger to transfer all the liquid to the bottle of BeneFIX.

The picture describes how the plunger is pushed into the syringe

11. Without removing the syringe from the adapter, gently rotate the bottle until the powder has dissolved.

The picture describes how the bottle is rotated

12. The finished solution should be inspected visually for particulate matter prior to administration . The solution should be clear and colorless.

Note: If you use more than one bottle of BeneFIX per injection , each bottle should be reconstituted according to the previous instructions. The diluent syringe should be removed, the bottle adapter left in place, and a separate large luer syringe (a device that connects the syringe to the bottle) can be used to draw the reconstituted contents from each bottle.

13. Make sure the syringe plunger is still fully depressed, and then turn the bottle upside down. Slowly withdraw all solution to the syringe.

The picture describes how all the solution is withdrawn to the syringe

14. Remove the syringe from the bottle adapter by gently pulling and screwing the syringe counterclockwise. Discard the bottle with its fitted adapter.

Note: If the solution is not to be used immediately, carefully place the spray cap back in place. Do not touch the top of the syringe or the inside of the cap.

BeneFIX should be administered immediately or within 3 hours after reconstitution . The reconstituted solution should be stored at room temperature before administration .

Administration ( intravenous injection )

BeneFIX should be administered using the supplied pre-filled syringe or steriledisposable plastic lure syringe. In addition, the solution should be withdrawn from the vial using the vial adapter

BeneFIX should be injected intravenously over several minutes. Your doctor may change your recommended injection rate to make the injection more comfortable for you.

There have been reports of agglutination of red blood cells in the tubing / syringe during administration of BeneFIX. No side effects have been reported as a result of this observation. To reduce the risk of sticking, it is important to limit the amount of blood that enters the tube. Blood should not enter the syringe. If red blood cellsticking in the tubing / syringe is observed, discard all affected material (tubing, syringe and BeneFIX solution) and continue administration with a new pack.

As continuous infusion (drip) of BeneFIX has not been evaluated, BeneFIX must not be mixed with infusion solutions or given as a drip.

Any unused solution, empty vials, used needles and syringes should be disposed of in an appropriate manner to avoid injury to others.

If you use more BeneFIX than you should

Contact your doctor immediately if you have injected more BeneFIX than your doctor recommended.

If you stop using BeneFIX

Do not stop using BeneFIX without consulting a doctor.

If you have any further questions on the use of this product, 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 reactions / allergic reactions

Allergic reactions such as hypersensitivity reactions are possible with BeneFIX. Such reactions may include swelling of the face or throat, burning and stinging sensation at the infusion site, chills, hot flashes, itching , headache, hives , low blood pressure , lethargy , nausea, restlessness, rapid heart rate, chest tightness, tingling, vomiting, wheezing. In some cases, these reactions have developed into severe anaphylaxis . Allergic reactions have occurred over time close to the development of factor IX inhibitors (see also “Warnings and Precautions”).

These reactions can be life-threatening. If allergic / anaphylactic reactions occur, discontinue infusion of BeneFIX immediately and contact your doctor or seek immediate emergency care. The treatment to be used depends on the nature and severity of the side effects (see also “Warnings and Precautions”).

Inhibitor development

Patients with haemophilia B may develop neutralizing antibodies (inhibitors) to factor IX. An indication that such inhibitors have been developed may be that an increase in the amount of BeneFIX normally required to treat a haemorrhage or continued haemorrhage after treatment is required. In such cases, it is recommended that a specialized haemophilia center be contacted. Your doctor may want to monitor you to see if any inhibitors develop (see “Warnings and Precautions”).

Renal impairment has been reported following high doses of plasma-derived factor IX products to induce immune tolerance in patients with haemophilia B and factor IX inhibitors and who have previously had allergic reactions (see also “Warnings and precautions”).

Blood clots

BeneFIX may increase the risk of thrombosis (formation of blood clots) in your body if you have risk factors for the formation of blood clots. A residual venous catheter can also be a risk factor for blood clots. There have been reports of severe thrombotic events, including life-threatening blood clots in severely ill newborns receiving BeneFIX by drip into a central venous catheter. Cases of peripheralthrombophlebitis (pain and redness of veins) and deep vein thrombosis (blood clots in the arms and legs) have also been reported. In most cases, BeneFIX had been administered by drip, which is not an approved method of administration.
