Descriptions

Factor IX Complex, Konyne (factor ix complex) ® 80, heat-treated at 80°C for 72 hours, is a sterile, dried, plasma fraction comprising coagulation factors II, IX, X and low levels of factor VII.

 

                                     Nomenclature

Factor:                         Synonyms:

II                                   prothrombin

VII                                proconvertin

IX                                 plasma thromboplastin component, PTC, Christmas factor

X                                   Stuart-Prower factor

Konyne (factor ix complex) 80 is standardized in terms of factor IX content and each vial of Konyne (factor ix complex) 80 is labeled for factor IX. One international unit (IU) of factor IX as defined by the World Health Organization standard for blood coagulation factor IX is approximately equal to the level of factor IX found in 1.0 mL of fresh, normal plasma.

The factor IX content is approximately 50 times purified over whole plasma, and when reconstituted as directed, Konyne (factor ix complex) 80 contains 25 times as much factor IX as an equal volume of fresh plasma. Konyne 80, containing approximately 1000 IU of factor IX administered in 40 mL, contains the factor IX content of 1 liter of fresh plasma. Konyne (factor ix complex) 80 must be administered intravenously.

What are the precautions when taking factor ix complex (Konyne)?

Before using factor IX, tell your doctor or pharmacist if you are allergic to factor IX products; or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.

Before using this medication, tell your doctor or pharmacist your medical history, especially of: other clotting disorders (e.g., disseminated intravascular coagulation-DIC), heart disease (e.g., coronary artery disease), immune system problems, recent surgery/procedure, liver disease.

Before having surgery, tell your doctor or dentist that you are using this medication.

Since this medication is made from human blood, there is a very small chance that you may get infections from it (e.g., viral...

Indications

Factor IX Complex, Konyne (factor ix complex) ® 80 is indicated for the prevention and control of bleeding caused by Factor IX deficiency due to hemophilia B.

Konyne (factor ix complex) 80 is not indicated for use in the treatment of factor VII deficiency.

Konyne (factor ix complex) 80 is appropriate for use in:

 

  1. Hemophilia B (Christmas disease); demonstrated factor IX deficiency in children or adults with real or impending bleeding episodes. Spontaneous bleeding can occur even in the absence of any trauma.
  2. Reversal of coumarin anticoagulant induced hemorrhage; in situations where prompt reversal is required (e.g., preceding emergency surgery, trauma, etc.), administration of fresh-frozen plasma should be initially considered as treatment; however, Konyne (factor ix complex) 80 may be considered as a secondary approach if the risk of transmitting hepatitis is considered justifiable in the face of a life-threatening situation. 6 - 8
  3. Treatment of bleeding episodes in patients with hemophilia A (factor VIII deficiency) who have inhibitors to factor VIII. 9
    In addition to coumarin anticoagulant induced deficiencies, low levels of factors II, VII, IX and X may be found in vitamin K deficiency, in patients with gut sterilization due to oral antibiotics, in patients with liver disease, and in those with nephrotic syndrome. However, Factor IX Complex, Konyne (factor ix complex) 80® is not indicated in these situations and treatment should be aimed at correcting the primary condition.

Note: For publications on the clinical use of Konyne (factor ix complex) ®, please refer to references 1,2, 6-17.

Dosage Administration

Each bottle of Konyne 80 has the factor IX activity, in IU, stated on the bottle label. One IU is defined as the activity present in 1 mL of fresh, normal plasma. The potency is standardized in terms of factor IX content.

The amount of Konyne (factor ix complex) 80 required for normalizing hemostasis will depend upon the patient and upon the circumstances. Sufficient Konyne (factor ix complex) 80 should be administered to achieve and maintain a plasma level of at least 20% until hemostasis is achieved.

Levels of factor IX of 30 to 40 percent are considered effective in stopping hemorrhages. 1 Bleeds in life- or limb-threatening areas require factor IX levels of 50 to 80 percent which should be maintained at 30 to 40 percent for a few days. 1 The desired hemostatic plasma level in surgical patients for minor procedures or invasive dental surgery is between 30 and 40 percent of normal. 1 This can be achieved by a dosage not exceeding 30 to 40 units per kg body weight. In major hemorrhage, as during surgery or severe accidental trauma, plasma levels of 60 to 80 percent just prior to surgery, maintained above 30 percent for a further 5 to 7 days and then above 15 to 20 percent for 7 to 10 additional days, until healing occurs, are required. 1

While the range of values in normal clinical practice is likely to vary depending upon differences between patients, their clinical condition and the type of assay employed, it is again stressed that high dosages, especially if frequently repeated (e.g., more than once per day) are hazardous. Such regimens can induce major thrombotic complications and hence must be avoided.

The following formulas may be used as guidelines to calculate an appropriate dose or to estimate the expected percentage increase obtained from a given dose:

Expected factor IX              = IU administered x 1.0
increase (in % of normal)           body weight (in kg)
IU required = body weight (kg) x desired factor IX increase (% normal) x 1.0

Thus, in order to bring a 70 kg patient from 0% to 50% of normal, the patient would require 70 x 50 x 1.0 = 3500 IU or 50 IU/kg body weight.

 

Prophylaxis

The ideal treatment for proven congenital deficiency of procoagulants is prophylactic administration. For prophylaxis against hemorrhage during times of extensive physical activity, the plasma factor IX levels should be raised to 15 to 30 percent. Maintenance dosage should be adapted to the individual patient's needs. Additional Factor IX Complex, Konyne (factor ix complex) ® 80 should be administered when a patient on prophylaxis is exposed to trauma or surgery.

Maintenance Dose

Maintenance dosage should be administered according to the clinical response and the factor IX level achieved. Such dosage is usually about 10-20 IU per kg body weight per day.

Inhibitor Patients

For treatment of bleeding episodes in patients with hemophilia A (factor VIII deficiency) who have inhibitors to factor VIII, the recommended dose should be 75 IU/kg. A second dose may be administered after 12 hours if necessary. 9

Reconstitution

Vacuum Transfer

 

  1. Warm the unopened diluent and concentrate to room temperature (NMT 37°C, 99°F).
  2. After removing the plastic flip-top caps aseptically cleanse the rubber stoppers of both bottles.
  3. Remove the protective cover from the plastic transfer-needle cartridge with tamper-proof seal and penetrate the stopper of the diluent bottle.
  4. Remove the remaining portion of the plastic cartridge. Invert the diluent bottle and penetrate the rubber seal on the concentrate bottle with the needle at an angle.
    Alternate method of transferring sterile water: With a sterile needle and syringe, withdraw the appropriate volume of diluent and transfer to the bottle of lyophilized concentrate.
  5. Hold the diluent bottle at an angle to the concentrate bottle in order to direct the jet of diluent against the wall of the concentrate bottle. The vacuum will draw the diluent into the concentrate bottle. Avoid excessive foaming. Do not shake the concentrate bottle.
  6. After removing the diluent bottle and transfer-needle, optimal reconstitution time is achieved by swirling continuously until completely dissolved. Reconstitution can also be achieved by very gently agitating until dissolved.
    Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.
  7. After the concentrate powder is completely dissolved, withdraw the Factor IX Complex, Konyne (factor ix complex) ® 80 solution into the syringe through the filter needle which is supplied in the package. Replace the filter needle with an appropriate sterile injection needle, e.g., 21 gauge x 1 inch, and inject intravenously.
  8. If the same patient is to receive more than one bottle of Konyne (factor ix complex) 80, the contents of two bottles may be drawn into the same syringe through filter needles before attaching the vein needle.

Rate of Administration

The rate of administration should be adapted to the response of the individual patient, but is generally well-tolerated at a rate of approximately 100 IU per minute.

How Supplied

Factor IX Complex, Konyne® 80 is supplied in single dose bottles with the total IU of factor IX activity stated on the label of each bottle. A suitable volume of Sterile Water for Injection, USP, a sterile double-ended transfer needle, and a sterile filter needle are provided.

Warnings

 

1. Hepatitis and Viral Diseases

Konyne (factor ix complex) 80 is made from human plasma. Products made from human plasma may contain infectious agents, such as viruses, that can cause disease. The risk that such products will transmit an infectious agent has been reduced by screening plasma donors for prior exposure to certain viruses, by testing for the presence of certain current virus infections, and by inactivating certain viruses. Despite these measures, such products can still potentially transmit disease. There is also the possibility that unknown infectious agents may be present in such products. ALL infections thought by a physician possibly to have been transmitted by this product should be reported by the physician or other healthcare provider to Bayer Corporation [1-888-765-3203]. The physician should discuss the risks and benefits of this product with the patient, before prescribing or administering it to the patient.

Individuals who receive infusions of blood or plasma products may develop signs and/or symptoms of some viral infections, particularly hepatitis C. It is emphasized that hepatitis B vaccination is essential for patients with hemophilia and it is recommended that this be done at birth or diagnosis. 19,20 Hepatitis A vaccination is also recommended for hemophilic patients who are hepatitis A seronegative.

2 Thrombosis

Cases of patients developing postoperative thrombosis after treatment with Factor IX Complex have been described. Although thrombosis is a well-known risk of the postoperative period, it is found to be greater in these patients. 13-15 No other data are presently available. Until further surveys and more conclusive studies are available, Konyne (factor ix complex) 80 is only advised for patients undergoing elective surgery where the expected beneficial effects of its use outweigh the increased risk of the possibility of thrombosis. This applies especially to those who may be predisposed to thrombosis. Do not use in cases of known liver disease where there is any suspicion of intravascular coagulation or fibrinolysis.

Precautions

General

 

  1. Reconstitute only with Sterile Water for Injection, USP.
  2. Administer within 3 hours after reconstitution. Do not refrigerate after reconstitution.
  3. Administer only by the intravenous route.
  4. The administration equipment and any reconstituted Factor IX Complex, Konyne (factor ix complex) ® 80 not immediately used should be discarded.
  5. E-aminocaproic acid should not be administered with Factor IX Complex as this may increase the risk of thrombosis.
  6. Patients who receive Konyne (factor ix complex) 80 either postoperatively or with known liver disease should be kept under close observation for signs and symptoms of intravascular coagulation or thrombosis. Any suspicious findings of this nature indicate the dosage should be markedly decreased if the patient's conditions are such that the treatment cannot be discontinued entirely. In the event of thrombohemorrhagic disorders occurring, reduction in dosage should be considered, and treatment with heparin may be warranted. Although this preparation does not contain heparin, it has been suggested that reconstitution with heparin in a concentration of 2-5 IU per mL may reduce the risk of development of thrombosis. 17 However, thrombosis can occur even in the presence of heparin.
  7. Patients receiving Konyne (factor ix complex) 80 for prolonged periods should be continually monitored at least for levels of factors II, IX and X. The same comments as in No. 6 above are indicated. Half-lives of factors II and X are considerably longer than the half-life of factor IX. Hence frequent repeated high-dose administration may result in build-up of factors II and X, with increasing risk of thrombotic side effects.
  8. Product administration and handling of the needles must be done with caution. Percutaneous puncture with a needle contaminated with blood can transmit infectious viruses including HIV (AIDS) and hepatitis. Obtain immediate medical attention if injury occurs.
    Place needles in sharps container after single use. Discard all equipment including any reconstituted Konyne (factor ix complex) 80 product in accordance with biohazard procedures.

Pregnancy Category C

Animal reproduction studies have not been conducted with Konyne (factor ix complex) 80. It is also not known whether Konyne (factor ix complex) 80 can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Konyne (factor ix complex) 80 should be given to a pregnant woman only if clearly needed.

Information for Patient

Some viruses, such as parvovirus B19 or hepatitis A, are particularly difficult to remove or inactivate at this time. Parvovirus B19 most seriously affects pregnant women, or immune-compromised individuals.

Symptoms of parvovirus B19 infection include fever, drowsiness, chills and runny nose followed about 2 weeks later by a rash and joint pain. Evidence of hepatitis A may include several days to weeks of poor appetite, tiredness, and low-grade fever followed by nausea, vomiting, and pain in the belly. Dark urine and a yellowed complexion are also common symptoms. Patients should be encouraged to consult their physician if such symptoms appear.

This monograph has been modified to include the generic and brand name in many instances.

OverDose

Symptoms include disseminated intravascular coagulation (DIC).

ContrainDications

Liver disease with signs of intravascular coagulation or fibrinolysis, not for use in factor VII deficiencies, patients undergoing elective surgery.

This monograph has been modified to include the generic and brand name in many instances.

Clinical Pharamacology

Factor IX Complex raises the plasma level of factor IX and restores hemostasis in patients with factor IX deficiency. In general, a level of factor IX less than 5% of normal will give rise to spontaneous hemorrhage, while levels greater than 20% of normal will lead to satisfactory hemostasis even in the face of trauma or surgery. Approximately 30% to 50% of the factor IX activity can be detected in a hemophilia B (factor IX deficiency) recipient's plasma immediately after infusion. 1,2 The biological activity of the infused factor IX disappears from the plasma with a half-life of approximately 24 hours. 2 A pharmacokinetic study in six patients found similar recoveries and half-lives for Konyne (factor ix complex) ® 80 as for Konyne®-HT. It must be noted that administration of Factor IX Complex causes an increase in blood levels of factors II, VII, IX and X.

Factors II, VII, IX and X are the vitamin K dependent coagulation factors and are synthesized in the liver. Congenital deficiencies of each of the four factors do occur and may result in a bleeding tendency. Naturally low levels of the vitamin K dependent factors may also be found in vitamin K deficiency and in severe liver disease.

This product has been heated at 80°C for 72 hours and there is no evidence of adverse effects upon the product. In a study 3 designed to assess the effectiveness of heat treatment at 68°C for 72 hours, hepatitis naive chimpanzees were inoculated with heated Antihemophilic Factor (Human) and Factor IX Complex preparations to which had been previously added non-A, non-B hepatitis Hutchinson Strain 4 to a total level of 2500 chimpanzee infectious doses (CID). The chimpanzees receiving heated preparations failed to exhibit any symptoms of non-A, non-B hepatitis. In contrast, one chimpanzee receiving Antihemophilic Factor (Human) concentrate which was not heated after the non-A, non-B inoculum was added, developed abnormally elevated alanine aminotransferase (ALT) levels beginning 10 weeks postinoculation and liver histopathology at 6 weeks. From these results, it was concluded that the heat treatment employed inactivated a known quantity of non-A, non-B hepatitis: at least 2500 CID.

Additional in vitro studies 5 on the effect of heating Factor IX Complex, Konyne (factor ix complex) ® 80, in a dried state at 80°C for 72 hours, on virus inactivation were carried out with a number of viruses, including human immunodeficiency virus (HIV), added to Factor IX Complex prior to heating.

Consumer Overview Uses

IMPORTANT: HOW TO USE THIS INFORMATION: This is a summary and does NOT have all possible information about this product. This information does not assure that this product is safe, effective, or appropriate for you. This information is not individual medical advice and does not substitute for the advice of your health care professional. Always ask your health care professional for complete information about this product and your specific health needs.

 

FACTOR IX, HUMAN - INJECTION

 

(FACK-ter nine)

 

COMMON BRAND NAME(S): Alphanine SD, Konyne, Proplex T

 

USES: This medication is used to prevent or control bleeding in people with little or no factor IX (due to hemophilia B, Christmas disease). Factor IX is a protein (clotting factor) in the blood that works with other clotting factors to help the blood clot and therefore stop bleeding. People with little or no factor IX are at risk for bleeding longer after an injury/surgery or bleeding suddenly (often in the joints/muscle) without an obvious cause.

This medication should not be used to reverse the effects of "blood thinners" (e.g., warfarin). Most types of this medication should not be used to treat other types of factor deficiencies (e.g., factors II, VII, VIII, X) or factor problems (e.g., inhibitor to factor XIII). If you are using this medication for one of these conditions, consult your doctor or pharmacist to make sure that you are using the right product.

 

HOW TO USE: This medication is given by injection into a vein as directed by your doctor. Dosage is based on your medical condition (e.g., amount and location of bleeding), weight, and response to treatment.

Gently swirl the medication to mix. Do not shake. Some forms of this medication must be completely mixed into the liquid so that the liquid contains no particles. In these cases, do not use the liquid if it contains particles. Other forms of this medication may occasionally contain a few small particles in the vial, even if the medication is mixed correctly. In these cases, the particles will not affect how well the medication works and will be removed by the filter. If you have questions about whether your form of this medication may be used if it contains particles, or if you have other questions about the use of this medication, consult the doctor or pharmacist.

If you are giving this medication to yourself at home, learn all preparation and usage instructions from your health care professional. Learn how to store and discard medical supplies safely.

The medication in the vial and the supplies that come with the medication should be used only once. Do not reuse.

Tell your doctor if your condition persists or worsens.

Consumer Overview Side Effect

SIDE EFFECTS: Pain at injection site, chills, tingling, flushing, headache, nausea, or vomiting may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.

Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Tell your doctor right away if you have any serious side effects, including: swelling at injection site, fast heartbeat, shortness of breath, change in the amount of urine, swelling of the ankles/feet, pain/redness/swelling of arms or legs, new or increased bleeding/bruising.

Get medical help right away if any of these rare but very serious side effects occur: chest pain, trouble breathing, bluish fingers.

This medication is made from human blood. Even though donors are carefully screened and this medication goes through a special manufacturing process, there is a very small chance that you may get infections from the medication (e.g., viral infections such as hepatitis). Tell your doctor immediately if you develop any signs of hepatitis/another infection, including fever, persistent sore throat, unusual tiredness, persistent nausea/vomiting, yellowing eyes/skin, dark urine.

A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.

This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.
