Treating With GamaSTAN1
GamaSTAN is a human immune globulin where the polyclonal antibody contained within is a passive immunizing agent to neutralize viruses, such as hepatitis A and measles viruses, to prevent or ameliorate disease.
GamaSTAN is indicated for use in the following situations:
- GAMASTAN is indicated for prophylaxis following exposure to hepatitis A
- GamaSTAN is not indicated in persons with clinical manifestations of hepatitis A or in those exposed more than 2 weeks previously
- Prevention or modification of measles (rubeola) in susceptible persons exposed fewer than 6 days previously; a susceptible person is one who has not been vaccinated and has not had measles previously
- Passive immunization in immunocompromised patients to protect against varicella if varicella-zoster immune globulin (human) is not available
- May benefit women who have been exposed to rubella in the first trimester of pregnancy and who will not consider a therapeutic abortion
- Established history—more than 75 years of consistent supply and product support
- Mercury (thimerosal) free and not made with natural rubber latex
- US Food and Drug Administration (FDA) labeling for capacity to remove pathogenic prions
- Tamper-evident packaging
- 24-month shelf life
Peak levels of immunoglobulin G (IgG) are obtained approximately 2 days after intramuscular (IM) injection of GamaSTAN. The half-life of IgG in the circulation of individuals with normal IgG levels is 23 days.1
Thrombosis may occur with immune globulin products, including GamaSTAN. Risk factors may include: advanced age, prolonged immobilization, hypercoagulable conditions, history of venous or arterial thrombosis, use of estrogens, indwelling central vascular catheters, hyperviscosity, and cardiovascular risk factors. Thrombosis may occur in the absence of known risk factors. For patients at risk of thrombosis, do not exceed the recommended dose of GamaSTAN. Ensure adequate hydration in patients before administration. Monitor for signs and symptoms of thrombosis and assess blood viscosity in patients at risk for hyperviscosity.1

Safety Is a Priority1
The following GamaSTAN manufacturing steps contribute to inactivation and/or removal capacity:
- Caprylate precipitation
- Depth filtration
- Caprylate incubation
- Column chromatography
- Low pH final container incubation
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.
GamaSTAN is made from human blood and may carry a risk of transmitting infectious agents, eg, viruses, the vCJD agent, and, theoretically, the CJD agent.
Traceability and Transparency of Information
Grifols' manufacturing process has a comprehensive computer system called PediGri® that ensures full traceability from every donation.
- 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
