The tolerability and safety of GAMMAGARD LIQUID [Immune Globulin Infusion (Human)] 10% were evaluated in 44 patients with MMN who received a total of 983 infusions of GAMMAGARD LIQUID1

Reference1
  • The percentage of infusions for which patients on GAMMAGARD LIQUID experienced a headache was 2.9% compared with 2.3% of infusions for patients on placebo1
  • Two serious ARs in the clinical trial for MMN, each impacting one subject, were pulmonary embolism and blurred vision, both of which were judged to be treatment related1
  • In the study, among the 317 non-serious AEs, 176 were considered ARs. Of these, 126 were mild, 37 were moderate, and 13 were severe1
    • Mild: transient discomfort that resolves spontaneously or with minimal intervention
    • Moderate: limited impairment of function and resolves spontaneously or with minimal intervention with no sequelae
    • Severe: marked impairment of function or can lead to temporary inability to resume normal life pattern; requires prolonged intervention or results in sequelae

GAMMAGARD LIQUID is indicated as a maintenance therapy to improve muscle strength and disability in adult patients with Multifocal Motor Neuropathy (MMN).

WARNING: THROMBOSIS, RENAL DYSFUNCTION and ACUTE RENAL FAILURE

  • Thrombosis may occur with immune globulin products, including GAMMAGARD LIQUID. Risk factors may include advanced age, prolonged immobilization, hypercoagulable conditions, history of venous or arterial thrombosis, use of estrogens, indwelling vascular catheters, hyperviscosity, and cardiovascular risk factors. Thrombosis may occur in the absence of known risk factors.
  • Renal dysfunction, acute renal failure, osmotic nephrosis, and death may occur in predisposed patients with immune globulin intravenous (IGIV) products including GAMMAGARD LIQUID. Renal dysfunction and acute failure occur more commonly with IGIV products containing sucrose. GAMMAGARD LIQUID does not contain sucrose.
  • For patients at risk of thrombosis, administer GAMMAGARD LIQUID at the minimum dose and infusion rate practicable. Ensure adequate hydration in patients before administration. Monitor for signs and symptoms of thrombosis and assess blood viscosity in patients at risk of hyperviscosity.
  • GAMMAGARD LIQUID is contraindicated in patients who have a history of anaphylactic or severe systemic hypersensitivity reactions to the administration of human immune globulin. GAMMAGARD LIQUID is contraindicated in IgA-deficient patients with antibodies to IgA and a history of hypersensitivity.
  • HYPERSENSITIVITY: IgA deficient patients with antibodies to IgA are at greater risk of developing potentially severe hypersensitivity and anaphylactic reactions. In case of hypersensitivity, discontinue GAMMAGARD LIQUID infusion immediately and institute appropriate treatment.
  • RENAL DYSFUNCTION/FAILURE: Monitor renal function, including blood urea nitrogen, serum creatinine, and urine output in patients at risk of acute renal failure. Ensure that patients with pre-existing renal insufficiency are not volume depleted. For patients at risk for renal dysfunction or thrombotic events, administer GAMMAGARD LIQUID at the minimum infusion rate practicable.
  • Hyperproteinemia, increased serum viscosity, and hyponatremia may occur in patients receiving GAMMAGARD LIQUID.
  • THROMBOSIS: Thrombosis may occur following treatment with immune globulin products, including GAMMAGARD LIQUID. Monitor for signs and symptoms of thrombosis and assess blood viscosity in patients at risk for hyperviscosity.
  • Aseptic Meningitis Syndrome (AMS) may occur with IGIV treatment, and has been reported with intravenous (IV) use of GAMMAGARD LIQUID. AMS may occur more frequently with high dose (2 g/kg) IGIV treatment and/or rapid infusion of IGIV.
  • Hemolytic anemia can develop subsequent to GAMMAGARD LIQUID treatment due to enhanced RBC sequestration. Risk factors may include: high doses (e.g., ≥2 g/kg cumulative dose), non-O blood group, and underlying inflammation. Monitor patients for clinical signs and symptoms of hemolysis and delayed hemolytic anemia.
  • Transfusion-Related Acute Lung Injury (TRALI): Non-cardiogenic pulmonary edema has been reported in patients following treatment with IGIV products, including GAMMAGARD LIQUID. Monitor patients for pulmonary adverse reactions.
  • GAMMAGARD LIQUID is made from human blood. It may carry a risk of transmitting infectious agents, e.g., viruses, the variant Creutzfeldt-Jakob disease (vCJD) agent, and theoretically, the Creutzfeldt-Jakob disease agent. No confirmed cases of viral transmission or vCJD have been associated with GAMMAGARD LIQUID.
  • Passive transfer of antibodies may transiently impair the immune responses to live attenuated virus vaccines such as mumps, rubella, varicella, and measles. This passive transfer may also yield false positive serological testing results, with the potential for misleading interpretation.

The serious adverse reactions in the MMN (IV administration) clinical trial were pulmonary embolism and blurred vision. The most common adverse reactions observed in ≥ 5% of patients in the clinical trials were:

MMN (IV administration): Headache, chest discomfort, muscle spasms, muscular weakness, nausea, oropharyngeal pain, and pain in extremity.
