GAMUNEX demonstrated proven efficacy vs a 10% liquid IGIV-S/D comparator1

(Gamimune® N, 10% [Immune Globulin Intravenous (Human)])

GAMUNEX demonstrated proven efficacy vs a 10% liquid IGIV-S/D comparator - Visual Aid

Double-blind, parallel group, multicenter, therapeutic equivalence trial of 172 patients with PI (95% with common variable immunodeficiency [CVID] or hypogammaglobulinemia) randomized to receive GAMUNEX or Gamimune N, 10% [Immune Globulin Intravenous (Human)].1

  • No validated cases of pneumonia1
  • Significantly fewer cases of validated and clinically defined acute sinusitis (P=0.012)1
  • The number of patients with at least one validated infection during the 9-month study period was 9 (12%) for GAMUNEX and 17 (23%) for Gamimune N, 10%; (P=0.06)2

Dosing regimen options for GAMUNEX in PI

Dosing regimen options for GAMUNEX in PI
  • Maximum approved infusion rate of 0.08 mL/kg/min2

It is recommended that initial infusion rate be used for the first 30 minutes. If well tolerated, the rate may be gradually increased to a maximum of 0.08 mL/kg per minute (8 mg/kg per minute).2

Certain severe adverse drug reactions may be related to the rate of infusion. Slowing or stopping the infusion usually allows the symptoms to disappear promptly.2

Ensure that patients with pre-existing renal insufficiency are not volume depleted; discontinue if renal function deteriorates.2

For patients at risk of renal dysfunction or thromboembolic events, administer at the minimum infusion rate practicable.2

In clinical studies, the most common adverse reactions with Gamunex were headache, cough, injection site reaction, nausea, pharyngitis, and urticaria.2

The most serious adverse reaction was an exacerbation of autoimmune pure red cell aplasia in one subject.2

Important Safety Information for GAMUNEX

Gamunex, Immune Globulin Intravenous (Human), 10% Caprylate/Chromatography Purified, is indicated for the treatment of primary humoral immunodeficiency disease (PI), idiopathic thrombocytopenic purpura (ITP), and chronic inflammatory demyelinating polyneuropathy (CIDP).

Immune Globulin Intravenous (Human) products have been reported to be associated with renal dysfunction, acute renal failure, osmotic nephrosis and death. Patients predisposed to acute renal failure include patients with any degree of pre-existing renal insufficiency, diabetes mellitus, age greater than 65, volume depletion, sepsis, paraproteinemia, or patients receiving known nephrotoxic drugs. Especially in such patients, IGIV products should be administered at the minimum concentration available and the minimum rate of infusion practicable. While these reports of renal dysfunction and acute renal failure have been associated with the use of many of the licensed IGIV products, those containing sucrose as a stabilizer accounted for a disproportionate share of the total number. Gamunex does not contain sucrose. Glycine, a natural amino acid, is used as a stabilizer.

Gamunex is contraindicated in individuals with acute severe hypersensitivity reactions to Immune Globulin (Human). It is contraindicated in IgA deficient patients with antibodies against IgA and history of hypersensitivity.

There have been reports of noncardiogenic pulmonary edema [Transfusion-Related Lung Injury (TRALI)], hemolytic anemia, and aseptic meningitis in patients administered with IGIV.

Thrombotic events have been reported in association with IGIV. Patients at risk for thrombotic events may include those with a history of atherosclerosis, multiple cardiovascular risk factors, advanced age, impaired cardiac output, and/or known or suspected hyperviscosity. Hyperproteinemia, increased serum viscosity, and hyponatremia may occur in patients receiving IGIV therapy.

Gamunex is made from human plasma. Because this product is made from human plasma, it may carry a risk of transmitting infectious agents, e.g., viruses, and, theoretically, the Creutzfeldt-Jakob disease (CJD) agent.

In clinical studies, the most common adverse reactions with Gamunex were headache, fever, chills, hypertension, rash, nausea, and asthenia (in CIDP); headache, cough, injection site reaction, nausea, pharyngitis, and urticaria (in PI); and headache, vomiting, fever, nausea, back pain, and rash (in ITP). The most serious adverse reactions were pulmonary embolism (PE) in one subject with a history of PE (in CIDP), an exacerbation of autoimmune pure red cell aplasia in one subject (in PI), and myocarditis in one subject that occurred 50 days post-study drug infusion and was not considered drug related (in ITP).
