A Comprehensive HRIG Solution

HyperRAB (300 IU/mL) is the first and only high-potency human rabies immune globulin (HRIG) that enables the delivery of more of the total dose per mL at the wound site, no matter the wound size or patient weight.1-3

Home Vial

Pharma

HyperRAB is the only HRIG that offers all of the following1

  • 1/2 the volume of medication administered in a total dose, potentially resulting in fewer injections
  • 2X the concentration of rabies antibodies per mL at the wound site, no matter the size
  • 3 vial sizes, including 1 mL, 3 mL, and 5 mL
  • 3-year shelf life
  • Room temperature storage* (up to 6 months)
  • Reliable supply
  • Rabies education
  • Patient assistance program

Provide immediate protection with HyperRAB

HyperRAB is an HRIG that provides rapid immune coverage, indicated for postexposure prophylaxis (PEP), along with rabies vaccine, for all persons suspected of exposure to rabies.1,5 Review CDC guidelines for PEP.

For unvaccinated persons, the combination of HyperRAB and vaccine is recommended for both bite and nonbite exposures regardless of the time interval between exposure and initiation of PEP. Persons who have been previously immunized with rabies vaccine and have a confirmed adequate rabies antibody titer should receive only vaccine.1,6

Dosing and Administration

Dosing recommendations for HyperRAB

The recommended dose for HyperRAB is 20 IU/kg (0.0665 mL/kg) of actual body weight administered at the time of the first vaccine dose.1 HyperRAB can be given up to 7 days after the first dose of rabies vaccine.6

Clinical Efficacy

In an open-label, single-arm study of 12 healthy volunteers, rabies virus antibody titers were assessed following a single 20 IU/kg IM injection of HyperRAB. This was measured by a rapid fluorescent focus inhibition test (RFFIT).1, 10

Home list

HyperRAB (rabies immune globulin [human]) 300 IU/mL produced a substantial increase in antirabies virus antibody concentrations during a 21-day period in which peak values were achieved.1,10

  • Elevated antibody levels and the corresponding reciprocal titers persisted through day 21
  • Elevation in rabies antibody level was prompt and resulted in detectable titers of neutralizing antibody present by 24 hours (mean 0.113 IU/mL and mean titer 10.3 on day 1)
  • The reciprocal titer results from this study are comparable to an earlier open-label, single-center study of HyperRAB S/D in 8 subjects given a 20 IU/kg dose IM

Home study design

In the clinical study, subjects underwent a screening period of up to 21 days, when safety assessments and laboratory tests were performed to ascertain eligibility. A single IM dose of HyperRAB was administered to eligible subjects on day 0, followed by repeated measurements of rabies virus antibody concentrations on days 1, 2, 4, 6, 8, 10, 14, 18, and 21.1,10

How the unique HyperRAB manufacturing process works

Explanation of the plasma fractionation, IgG purification and formulation processes used to develop HyperRAB

Home end-to-end

The capacity of the HyperRAB manufacturing process to remove and/or inactivate viruses has been demonstrated by laboratory spiking studies on a scaled-down process model using a wide range of viruses with diverse physicochemical properties. This process provides the final product with a high margin of safety from the potential risk of transmission of infectious viruses.

The caprylate/chromatography manufacturing process was also investigated for its capacity to decrease the infectivity of an experimental agent of transmissible spongiform encephalopathy (TSE), considered as a model for the variant Creutzfeldt-Jakob disease (vCJD) and Creutzfeldt-Jakob disease (CJD) agents. These studies provide reasonable assurance that low levels of vCJD/CJD agent infectivity, if present in the starting material, would be removed by the caprylate/chromatography manufacturing process.

Home additional safeguards

HyperRAB is made from human blood and may carry a risk of transmitting infectious agents, eg, viruses, the vCJD agent, and, theoretically, the CJD agent.

Additional safeguards for all plasma donations

Grifols employs a comprehensive tracking system called PediGri® that ensures full traceability from every donation.

Home Traceability

  • Each plasma unit is coded and computer-traced from the start of the process until the units are transformed into a final product
  • Users can access the donation number and the viral screening conducted at the origin of the donation with the product lot number
    • Specific information is also available, including the total number of plasma units, the total volume of plasma, the certificate of analysis showing the plasma origin viral screening, and biochemical characteristics of the final product
  • Users can access the applicable product SPC/package insert for their country

Indication and Usage

HYPERRAB® (rabies immune globulin [human]) is indicated for postexposure prophylaxis, along with rabies vaccine, for all persons suspected of exposure to rabies.

Limitations of Use 

Persons who have been previously immunized with rabies vaccine and have a confirmed adequate rabies antibody titer should receive only vaccine.

For unvaccinated persons, the combination of HYPERRAB and vaccine is recommended for both bite and nonbite exposures regardless of the time interval between exposure and initiation of postexposure prophylaxis.

Beyond 7 days (after the first vaccine dose), HYPERRAB is not indicated since an antibody response to vaccine is presumed to have occurred.

Important Safety Information

For infiltration and intramuscular use only.

Severe hypersensitivity reactions may occur with HYPERRAB. Patients with a history of prior systemic allergic reactions to human immunoglobulin preparations are at a greater risk of developing severe hypersensitivity and anaphylactic reactions. Have epinephrine available for treatment of acute allergic symptoms, should they occur.

HYPERRAB is made from human blood and may carry a risk of transmitting infectious agents, eg, viruses, the variant Creutzfeldt-Jakob disease (vCJD) agent, and, theoretically, the Creutzfeldt-Jakob disease (CJD) agent.

The most common adverse reactions in >5% of subjects during clinical trials were injection-site pain, headache, injection-site nodule, abdominal pain, diarrhea, flatulence, nasal congestion, and oropharyngeal pain.

Do not administer repeated doses of HYPERRAB once vaccine treatment has been initiated as this could prevent the full expression of active immunity expected from the rabies vaccine.

Other antibodies in the HYPERRAB preparation may interfere with the response to live vaccines such as measles, mumps, polio, or rubella. Defer immunization with live vaccines for 4 months after HYPERRAB administration.
