Medical Benefits
Pharmacies must register here to request assistance for their eligible Gammaplex 5% or Gammaplex 10% patients covered under medical benefits.
Pharmacy Benefits
If the patient’s primary payer drug claim is billed under pharmacy benefits, submit the claim to the primary payer first. If the patient requires co-pay assistance, submit the balance due to Medmonk as a secondary payer (COB - Coordination of Benefits) using the BIN: 016664, PCN: MEDMONK, and Cardholder ID: MEDMONK
Timely Filing
Claims must be received within 30 days of dispense date. For medical benefits, EOBs must be submitted within 120 days of claim submission.

Important Safety Information

Gammaplex® 10% (immune globulin intravenous [human], 10% liquid) is indicated for replacement therapy in primary humoral immunodeficiency (PI) in adults. This includes, but is not limited to, the humoral immune defect in common variable immunodeficiency, X-linked agammaglobulinemia, congenital agammaglobulinemia, Wiskott-Aldrich syndrome, and severe combined immunodeficiencies.

Gammaplex 10% is also indicated for the treatment of chronic immune thrombocytopenic purpura (ITP) in adults.

Thrombosis may occur with immune globulin products, including Gammaplex 10%. 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.

Renal dysfunction, acute renal failure, osmotic nephrosis, and death may occur in predisposed patients who receive immune globulin intravenous (IGIV) products, including Gammaplex 10%.

Patients predisposed to renal dysfunction include those with any degree of pre-existing renal insufficiency, diabetes mellitus, age greater than 65, volume depletion, sepsis, paraproteinemia, or patients receiving known nephrotoxic drugs. Renal dysfunction and acute renal failure occur more commonly in patients receiving IGIV products containing sucrose. Gammaplex 10% does not contain sucrose.

For patients at risk of thrombosis, renal dysfunction or acute renal failure, administer Gammaplex 10% 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 for hyperviscosity.

Gammaplex 10% is contraindicated in patients who have had a history of anaphylactic or severe systemic reactions to human immune globulin and IgA deficient patients with antibodies to IgA and a history of hypersensitivity.

In patients at risk of developing acute renal failure, monitor renal function, including blood urea nitrogen (BUN), serum creatinine and urine output. Hyperproteinemia, increased serum viscosity, and hyponatremia may occur in patients receiving IGIV therapy.

Aseptic meningitis syndrome (AMS) may occur infrequently with IGIV treatment. AMS usually begins within several hours to 2 days following IGIV treatment. Discontinuation of IGIV treatment has resulted in remission of AMS within several days without sequelae. AMS may occur more frequently in association with high doses (2 g/kg) and/or rapid infusion of IGIV.

Hemolysis and hemolytic anemia can develop subsequent to IGIV treatments. Patient risk factors that may be associated with development of hemolysis include high dose (>2 g/kg), non-O blood group, and underlying inflammatory state. Noncardiogenic pulmonary edema may occur in patients following IGIV treatment (i.e. transfusion-related acute lung injury [TRALI]). Monitor patients for pulmonary adverse reactions. If TRALI is suspected, test product and patient’s serum for anti-neutrophil antibodies.

Gammaplex 10% is made from human plasma and may contain infectious agents, e.g. viruses and, theoretically, the Creutzfeldt-Jakob disease agent. No cases of transmission of viral diseases or CJD have been associated with the use of Gammaplex 10%.

The most common adverse reactions in adult subjects receiving Gammaplex 10% in the PI clinical trial were headache, migraine, and pyrexia. There were no serious product-related adverse reactions observed in adult clinical trial subjects with PI. The safety of Gammaplex 10% has not been established in patients with ITP. However, the safety profile for Gammaplex 5% has been studied in subjects with ITP, and it is anticipated that the safety profile for both formulations are comparable for ITP patients. The most common adverse reactions in adult subjects receiving Gammaplex 5% in the chronic ITP clinical trial were headache, vomiting, nausea, pyrexia, arthralgia, and dehydration. Serious adverse reactions observed in clinical trial subjects with ITP were headache, vomiting and dehydration.
