PATIENT SUPPORT

Indication

ASCENIV™ (immune globulin intravenous, human–slra) is a 10% immune globulin liquid for intravenous injection, indicated for the treatment of primary humoral immunodeficiency (PI) in adults and pediatric patients (2 years of age and older). PI includes, but is not limited to, the humoral immune defect in congenital agammaglobulinemia, common variable immunodeficiency (CVID), X linked agammaglobulinemia, Wiskott-Aldrich syndrome, and severe combined immunodeficiencies (SCID).

Important Safety Information for ASCENIV

Contraindications

ASCENIV is contraindicated in:

• Patients who have had an anaphylactic or severe systemic reaction to the administration of human immune globulin.
• IgA-deficient patients with antibodies to IgA and a history of hypersensitivity.

Warnings and Precautions

Severe hypersensitivity reactions may occur with IGIV products, including ASCENIV. In case of hypersensitivity, discontinue ASCENIV infusion immediately and institute appropriate treatment. Medications such as epinephrine should be available for treatment of acute hypersensitivity reactions. Patients with known antibodies to IgA may have a greater risk of developing severe hypersensitivity and anaphylactic reactions.

Thrombosis may occur following treatment with immune globulin products, including ASCENIV, and in the absence of known risk factors. Consider baseline assessment of blood viscosity in patients at risk for hyperviscosity and ensure adequate hydration before administration. For patients at risk of thrombosis, administer ASCENIV at the minimum dose and infusion rate practicable. Monitor for signs and symptoms of thrombosis and assess blood viscosity in patients at risk for hyperviscosity.

Acute renal dysfunction, acute renal failure, acute tubular necrosis, proximal tubular nephropathy, osmotic nephrosis, and death may occur upon use of human IGIV products. Ensure that patients are not volume depleted before administering ASCENIV. Periodic monitoring of renal function and urine output is particularly important in patients at increased risk of developing acute renal failure. Assess renal function, including measurement of blood urea nitrogen (BUN) and serum creatinine, before the initial infusion of ASCENIV and at appropriate intervals thereafter. Discontinue ASCENIV if renal function deteriorates. In at risk patients, administer ASCENIV at the minimum infusion rate practicable.

Hyperproteinemia, hyperviscosity, and hyponatremia may occur in patients receiving IGIV treatment, including ASCENIV. It is critical to clinically distinguish true hyponatremia from a pseudohyponatremia that is associated with or causally related to hyperproteinemia. Treatment aimed at decreasing serum free water in patients with pseudohyponatremia may lead to volume depletion, a further increase in serum viscosity, and a possible predisposition to thrombotic events.

Aseptic meningitis syndrome (AMS) may occur with IGIV treatments, including ASCENIV. AMS usually begins within several hours to 2 days following IGIV treatment. The risk of AMS may be higher with high doses (≥2 g/kg) and/or rapid infusion of IGIV. Conduct a thorough neurological examination on patients exhibiting signs and symptoms of AMS, including cerebrospinal fluid (CSF) studies, to rule out other causes of meningitis. Discontinuation of IGIV treatment has resulted in remission of AMS within several days without sequelae.

Hemolysis may occur after administration of IGIV products, including ASCENIV, due to the presence of blood group antibodies that can act as hemolysins and induce in vivo coating of red blood cells (RBCs) with immunoglobulin, causing a positive direct antiglobulin test and hemolysis. The risk factors for hemolysis include high doses (e.g., ≥2 g/kg) given either as a single administration or divided over several days, non-O blood group, and an underlying inflammatory disease condition. Monitor patients for clinical signs and symptoms of hemolysis, including appropriate confirmatory laboratory testing.

Transfusion-Related Acute Lung Injury (TRALI) may occur in patients following IGIV treatment, including ASCENIV. Monitor patients for pulmonary adverse reactions. If TRALI is suspected immediately stop ASCENIV infusion and perform appropriate tests for presence of anti-neutrophil antibodies and anti-human leukocyte (HLA) antibodies in both product and patient’s serum. Manage patients using oxygen therapy with adequate ventilatory support as appropriate.

There is risk of transmitting infectious agents including viruses, the variant Creutzfeldt-Jakob disease (vCJD) and the Creutzfeldt-Jakob disease (CJD) agent with ASCENIV administration because it is manufactured using human blood. All infections suspected to have been transmitted by ASCENIV should be reported by the physician or other healthcare provider to ADMA Biologics at (1-800-458-4244).

After infusion of immunoglobulin, the transitory rise of the various passively transferred antibodies in the patient’s blood may yield positive serological testing results, with the potential for misleading interpretation. Passive transmission of antibodies to erythrocyte antigens (e.g., A, B, and D) may cause a positive direct or indirect antiglobulin (Coombs’) test.

Adverse Reactions

The most common adverse reactions to ASCENIV (≥5% of study patients) were headache, nausea, otitis, sinusitis, fatigue, chest pain, muscle spasm, acute sinusitis, diarrhea, hypersensitivity, viral rash, vomiting, bronchitis, epistaxis, muscle pain, oropharyngeal pain, pain in extremity and itching.
