Description

11 DESCRIPTION BIVIGAM is a purified, sterile, ready-to-use preparation of concentrated human immunoglobulin G (IgG) antibodies. The distribution of IgG subclasses is similar to that of normal plasma. 19,20 The active ingredient is human immunoglobulin purified from source human plasma and processed using a modified classical Cohn Method 6 / Oncley Method 9 fractionation process as well as anion and cation exchange steps for added purification. BIVIGAM contains 100 ± 10 mg/mL protein, of which not less than 96% is human immunoglobulin obtained from source human plasma. It is formulated in water for injection containing 0.100-0.140 M sodium chloride, 0.20-0.29 M glycine, 0.15–0.25% polysorbate 80, and pH 4.0–4.6. BIVIGAM contains ≤ 200 µg/mL of IgA. Each plasma donation used for the manufacture of BIVIGAM is collected from FDA licensed facilities and undergoes rigorous testing. Plasma donations must test negative for hepatitis B virus (HBV) surface antigen (HBsAg), antibodies to human immunodeficiency virus (HIV) strains 1 and 2 (anti-HIV-1/2), and antibodies to the hepatitis C virus (anti-HCV) as determined by enzyme immuno assay (EIA). In addition, each plasma unit must test negative and/or non-reactive for HIV RNA, HCV RNA, HBV DNA, Hepatitis A Virus (HAV) RNA, and Parvovirus B19 (B19 virus) DNA as determined by Nucleic Acid Amplification Testing (NAT) of plasma minipools. NAT is also performed on a sample of the manufacturing pool and must be negative and/or non-reactive for HIV RNA, HCV RNA, HBV DNA, and Hepatitis A Virus (HAV) RNA, and the limit for B19 virus DNA in a manufacturing pool is set not to exceed 10 4 IU/mL. The manufacturing process of BIVIGAM employs six steps to remove/inactivate adventitious viruses to minimize the risk of virus transmission. The steps are "Precipitation and removal of fraction III" during cold ethanol fractionation, “Q-membrane filtration”, "Solvent/detergent treatment" (TnBP/ Triton X-100), “Anion exchange chromatography” and...

What Is Immune Globulin Intravenous (Human) 10% Used For?

1 INDICATIONS AND USAGE BIVIGAM is an Immune Globulin Intravenous (Human), 10% Liquid, indicated for the treatment of adults and pediatric patients 2 years of age and older with primary humoral immunodeficiency (PI). [1] 1.1 Primary Humoral Immunodeficiency BIVIGAM is an Immune Globulin Intravenous (Human), 10% Liquid, indicated for the treatment of adults and pediatric patients 2 years of age and older with primary humoral immunodeficiency (PI). This includes, but is not limited to, the humoral immune defect in common variable immunodeficiency (CVID), X-linked agammaglobulinemia, congenital agammaglobulinemia, Wiskott-Aldrich syndrome, and severe combined immunodeficiencies.

Dosage and Administration

2 DOSAGE AND ADMINISTRATION For Intravenous Use Only Intravenous Use Only Indication Dose Initial Infusion Rate Maintenance Infusion Rate (if tolerated) PI 300-800 mg/kg every 3-4 weeks 0.5 mg/kg/min for first 10 minutes Increase every 20 minutes (if tolerated) by 0.8 mg/kg/min up to 6 mg/kg/min. Ensure that patients with pre-existing renal insufficiency are not volume depleted; discontinue BIVIGAM if renal function deteriorates. [5.3] For patients at risk of renal dysfunction or thrombotic events, administer BIVIGAM at the minimum infusion rate practicable. [5.1 , 5.3] 2.1 Preparation and Handling BIVIGAM is a clear or slightly opalescent, colorless to pale yellow solution. Inspect BIVIGAM visually for particulate matter and discoloration prior to administration. Do not use if the solution is cloudy or turbid, or contains particulate matter. Allow refrigerated product to come to room temperature before use. Do not freeze or heat. Do not use any solution that has been frozen or heated. DO NOT SHAKE. Do not mix BIVIGAM with other IGIV products or other intravenous medications. If large doses of BIVIGAM are to be administered, several vials may be pooled using aseptic technique into sterile infusion bags and infused. Do not dilute BIVIGAM. BIVIGAM contains no preservatives. BIVIGAM vial is for single use only. Any vial of BIVIGAM that has been entered should be used promptly and any unused portion should be discarded immediately. Do not reuse or save for future use. Maintain BIVIGAM at room temperature during administration. Do not use after expiration date. 2.2 Recommended Dose As there are significant differences in the half-life of IgG among patients with primary humoral immunodeficiency, the frequency and amount of immunoglobulin therapy may vary from patient to patient. The proper amount can be determined by monitoring clinical response. The recommended dose of BIVIGAM for replacement therapy in primary humoral immunodeficiency in adults and children 2 years of age and older, is 300 to 800 mg/kg body weight administered every 3 to 4 weeks. The dosage may be adjusted over time to achieve the desired trough levels and clinical response. BIVIGAM dose adjustments may be required in patients who fail to maintain trough total IgG concentrations of at least 500 mg/dL with a target of 600 mg/dL. Starting with the second infusion, the dose will be adjusted proportionally, targeting a trough of ≥ 600 mg/dL, based on the previous trough and the associated dose. 2.3 Administration It has been reported that the frequency of adverse drug reactions to IGIV increases with the infusion rate. Initial infusion rates should be slow. If there are no adverse drug reactions, the infusion rate for subsequent infusions can be slowly increased to the maximum rate. For patients experiencing adverse drug reactions, it is advisable to reduce the infusion rate in subsequent infusions.

Side Effects (Adverse Reactions)

6 ADVERSE REACTIONS Serious adverse reactions observed in clinical trial subjects receiving BIVIGAM were vomiting and dehydration in one subject. The most common adverse reactions to BIVIGAM (reported in ≥5% of clinical study subjects) were headache, fatigue, infusion site reaction, nausea, sinusitis, blood pressure increased, diarrhea, dizziness, and lethargy. The most common adverse reactions to BIVIGAM (reported in ≥5% of clinical study subjects) were headache, fatigue, infusion site reaction, nausea, sinusitis, blood pressure increased, diarrhea, dizziness, and lethargy. [6] To report SUSPECTED ADVERSE REACTIONS, contact ADMA Biologics at (800) 458-4244 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in clinical trials cannot be directly compared to rates in the clinical trials of another product and may not reflect the rates observed in clinical practice. In a multicenter, open-label, non-randomized clinical trial, 63 subjects with PI, on regular IGIV replacement therapy, received doses of BIVIGAM ranging from 254 to 1029 mg/kg (median dose 462.8 mg/kg) every 3 weeks or 4 weeks for up to 12 months (mean 317.3 days; range 66 – 386 days) ( see Clinical Studies [ 14 ] ). The use of pre-medication was discouraged; however, if subjects required pre-medication (antipyretic, antihistamine, or antiemetic agent) for recurrent reactions to immune globulins, they were allowed to continue those medications for this trial. Of the 746 infusions administered, 41 (65%) subjects received premedication prior to 415 (56%) infusions. Fifty-nine subjects (94%) had an adverse reaction at some time during the study. The proportion of subjects who had at least one adverse reaction was the same for both the 3- and 4-week cycles. The most common adverse reactions observed in this clinical trial were headache (32 subjects, 51%), sinusitis (24 subjects, 38%), fatigue (18 subjects, 29%), upper respiratory tract infection (16 subjects, 25%), diarrhea (13 subjects, 21%), cough (14 subjects, 22%), bronchitis (12 subjects, 19%), pyrexia (12 subjects, 19%), and nausea (9 subjects, 14%). Adverse reactions (ARs) are those occurring during or within 72 hours after the end of an infusion. In this study, the upper bound of the 1-sided 95% confidence interval for the proportion of BIVIGAM infusions with one or more temporally associated adverse reactions was 31%. The total number of adverse reactions was 431 (a rate of 0.58 ARs per infusion). Table 2: Adverse Reactions (ARs) (within 72 hours after the end of a BIVIGAM infusion) in ≥5% of Subjects ARs No. Subjects Reporting ARs (% of Subjects) [n=63] No. Infusions With ARs (% of Infusions) [n=746] Headache 27 (43%) 115 (15.4%) Fatigue 15 (24%) 59 (7.9%) Infusion Site Reaction 5 (8%) 5 (0.7%) Nausea 5 (8%) 8 (1.1%) Sinusitis 5 (8%) 5 (0.7%) Blood Pressure Increased 4 (6%) 5 (0.7%) Diarrhea 4 (6%) 4 (0.5%) Dizziness 4 (6%) 4 (0.5%) Lethargy 4 (6%) 4 (0.5%) Back Pain 3 (5%) 3 (0.4%) Blood Pressure Diastolic Decreased 3 (5%) 5 (0.7%) Fibromyalgia a 3 (5%) 17 (2.3%) Migraine 3 (5%) 8 (1.1%) Myalgia 3 (5%) 4 (0.5%) Pharyngolaryngeal Pain 3 (5%) 3 (0.4%) a Symptoms occurring under pre-existing fibromyalgia Seven subjects (11.1%) experienced 11 serious ARs. Two of these were related serious ARs (vomiting and dehydration) that occurred in one subject. One subject withdrew from the study due to ARs related to BIVIGAM (lethargy, headache, tachycardia and pruritus). All 63 subjects enrolled in this study had a negative direct antiglobulin (Coombs’) test at baseline. During the study, no subjects showed clinical evidence of hemolytic anemia. No cases of transmission of viral diseases or CJD have been associated with the use of BIVIGAM. During the clinical trial no subjects tested positive for infection due to human immunodeficiency virus (HIV), hepatitis B virus (HBV), or hepatitis C virus...

Drug Interactions

7 DRUG INTERACTIONS Passive transfer of antibodies may transiently interfere with the immune response to live virus vaccines, such as measles, mumps, rubella, and varicella. [7] Passive transfer of antibodies may confound the results of serological testing. [5.10] 7.1 Live Virus Vaccines Immunoglobulin administration may transiently impair the efficacy of live attenuated virus vaccines such as measles, mumps, rubella, and varicella because the continued presence of high levels of passively acquired antibody may interfere with an active antibody response. 15,16 The immunizing physician should be informed of recent therapy with BIVIGAM so that appropriate measures may be taken (see Patient Counseling Information [17.7] ).

Contraindications

4 CONTRAINDICATIONS BIVIGAM is contraindicated in patients who have had an anaphylactic or severe systemic reaction to the administration of human immune globulin. BIVIGAM is contraindicated in IgA deficiency patients with antibodies to IgA and a history of hypersensitivity. History of anaphylactic or severe systemic reactions to human immunoglobulin. [4] IgA deficient patients with antibodies to IgA and a history of hypersensitivity. [4 , 5.2]

Pregnancy and Breastfeeding

8.1 Pregnancy No human data are available to indicate the presence or absence of drug-associated risk. Animal reproductive studies have not been conducted with BIVIGAM. It is not known whether BIVIGAM can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Immune globulins cross the placenta from maternal circulation increasingly after 30 weeks of gestation. BIVIGAM should be given to pregnant women only if clearly needed. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively.
