HyperHep B

DRUG DESCRIPTION

Hepatitis B Immune Globulin (Human) HyperHEP B S/D treated with solvent/detergent is a sterile solution of hepatitis B hyperimmune immune globulin for intramuscular administration; it is preservative-free and latex-free. HyperHEP B S/D is prepared by cold ethanol fractionation from the plasma of donors with high titers of antibody to the hepatitis B surface antigen (anti-HBs). The immune globulin is isolated from solubilized Cohn Fraction II. The Fraction II solution is adjusted to a final concentration of 0.3% tri-n-butyl phosphate (TNBP) and 0.2% sodium cholate. After the addition of solvent (TNBP) and detergent (sodium cholate), the solution is heated to 30C and maintained at that temperature for not less than 6 hours. After the viral inactivation step, the reactants are removed by precipitation, filtration and finally ultrafiltration and diafiltration. HyperHEP B S/D is formulated as a 1518% protein solution at a pH of 6.47.2 in 0.210.32 M glycine. HyperHEP B S/D is then incubated in the final container for 2128 days at 2027C. Each vial contains anti-HBs antibody equivalent to or exceeding the potency of anti-HBs in a U.S. reference hepatitisB immune globulin (Center for Biologics Evaluation and Research, FDA). The U.S. reference has been tested against the World Health Organization standard Hepatitis B Immune Globulin and found to be equal to 220international units (IU) per mL.

The removal and inactivation of spiked model enveloped and non-enveloped viruses during the manufacturing process for HyperHEP B S/D has been validated in laboratory studies. Human Immunodeficiency Virus, Type 1 (HIV-1), was chosen as the relevant virus for blood products; Bovine Viral Diarrhea Virus (BVDV) was chosen to model Hepatitis C virus; Pseudorabies virus (PRV) was chosen to model Human Herpes viruses and other large enveloped DNA viruses; and Reo virus type 3 (Reo) was chosen to model non-enveloped viruses and for its resistance to physical and chemical inactivation. Significant removal of model enveloped and non-enveloped viruses is achieved at two steps in the Cohn fractionation process leading to the collection of Cohn Fraction II: the precipitation and removal of Fraction III in the processing of Fraction II + IIIW suspension to Effluent III and the filtration step in the processing of Effluent III to Filtrate III. Significant inactivation of enveloped viruses is achieved at the time of treatment of solubilized Cohn Fraction II with TNBP/sodium cholate.

Additionally, the manufacturing process was investigated for its capacity to decrease the infectivity of an experimental agent of transmissible spongiform encephalopathy (TSE), considered as a model for the vCJD and CJD agents.2225

Studies of the HyperHEP B S/D manufacturing process demonstrate that TSE clearance is achieved during the Pooled Plasma to Effluent III Fractionation Process (6.7 log10). These studies provide reasonable assurance that low levels of CJD/vCJD agent infectivity, if present in the starting material, would be removed.

This medication is made from human blood. Even though the blood is carefully tested, and this medication goes through a special manufacturing process, there is an extremely small chance that you may get infections (such as hepatitis A) from the medication. Consult your doctor or pharmacist for more information.

Some immune globulin products are made with maltose. This substance can cause false high blood sugar levels when your blood sugar is normal or even low. If you have diabetes, check with your doctor or pharmacist whether the product you are using contains maltose and whether your blood sugar testing supplies will work with this product. Rarely, serious problems have occurred when too much insulin was given because of false high sugar readings or when low blood sugar went untreated.

Tell your doctor of any recent/planned vaccinations. This medication may prevent a good response to live virus vaccines (such as measles, mumps, varicella). If you are vaccinated less than 14 days before receiving this medication or during the 3 months after receiving this medication, you may need to be vaccinated again or tested to see whether the vaccine was effective.

During pregnancy, this medication should be used only when clearly needed. Discuss the risks and benefits with your doctor.

What is hepatitis B immune globulin (HyperHep B)?

Hepatitis B immune globulin is made from human plasma containing proteins that protect against the type B form of hepatitis (inflammation of the liver).

Hepatitis B immune globulin is used to prevent hepatitis B in people receiving a liver transplant, and in babies born to mothers infected with hepatitis B. It is also used to prevent hepatitis B in people who have been exposed to contaminated blood products, or through household or sexual contact with an infected person.

Hepatitis B immune globulin is not a vaccine. Therefore it will not provide long-term protection from hepatitis B. For long-term protection you must receive a hepatitis B vaccine such as Engerix-B, Recombivax HB, or Twinrix.

Hepatitis B immune globulin may also be used for other purposes not listed in this medication guide.

What are the possible side effects of hepatitis B immune globulin (HyperHep B)?

Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.

Call your doctor at once if you have any of these serious side effects:

  • increased blood pressure (severe headache, blurred vision, trouble concentrating, chest pain, numbness, seizure);
  • left-sided stomach pain; or
  • nausea, stomach pain, low fever, loss of appetite, dark urine, clay-colored stools, jaundice (yellowing of the skin or eyes).

Less serious side effects may include:

  • upset stomach, diarrhea;
  • tremors or shaking;
  • joint or back pain;
  • fever, chills;
  • headache; or
  • tired feeling.

This is not a complete list of side effects and others may occur. Tell your doctor about any unusual or bothersome side effect. You may report side effects to FDA at 1-800-FDA-1088.

What is the most important information I should know about hepatitis B immune globulin (HyperHep B)?

Hepatitis B immune globulin is not a vaccine. Therefore it will not provide long-term protection from hepatitis B. For long-term protection you must receive a hepatitis B vaccine such as Engerix-B, Recombivax HB, or Twinrix.

You should not receive this medication if you are allergic to human globulins, or if you have an immunoglobulin A deficiency. Hepatitis B immune globulin should not be injected into your muscle if you have a bleeding or blood clotting disorder such as hemophilia.

Hepatitis B immune globulin is made from human plasma (part of the blood) and may contain viruses and other infectious agents that can cause disease. Although donated human plasma is screened, tested, and treated to reduce the risk of it containing anything that could cause disease, there is still a small possibility it could transmit disease. Talk with your doctor about the risks and benefits of using this medication.

To be sure this medication is helping your condition, your blood will need to be tested often. This will help your doctor determine how long to treat you with hepatitis B immune globulin. Your liver function will also need to be tested. Do not miss any scheduled visits to your doctor.

Do not receive a "live" vaccine while you are being treated with hepatitis B immune globulin, and for at least 3 months after your treatment ends. The live vaccine may not work as well during this time, and may not fully protect you from disease.
