Product Label Table of Contents

Warning: Thrombosis, Renal Dysfunction, And Acute Renal Failure

Thrombosis may occur with immune globulin intravenous (IGIV) products, including PANZYGA. 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. (See WARNING and PRECAUTIONS [ 5.4 ], PATIENT COUNSELING INFORMATION [ 17 ])

Renal dysfunction, acute renal failure, osmotic nephrosis, and death may occur in predisposed patients who receive IGIV products, including PANZYGA. Patients predisposed to renal dysfunction include those with a 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 product containing sucrose. PANZYGA does not contain sucrose.

For patients at risk of thrombosis, renal dysfunction or acute renal failure, administer PANZYGA 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. (See DOSAGE and ADMINISTRATION [ 2.3 ], WARNINGS and PRECAUTIONS [ 5.2 , 5.4 ])

1.1 Primary Humoral Immunodeficiency Diseases (Pi)

PANZYGA is indicated for treatment of primary humoral immunodeficiency (PI) in patients 2 years of age and older. This includes, but is not limited to, congenital agammaglobulinemia, common variable immunodeficiency, X-linked agammaglobulinemia, Wiskott-Aldrich syndrome, and severe combined immunodeficiencies.

1.2 Chronic Immune Thrombocytopenia (Itp)

PANZYGA is indicated for the treatment of adult patients with ITP to raise platelet counts to control or prevent bleeding.

2 Dosage And Administration

For intravenous use only.

2.1 Dose

Indication Dose Initial Infusion Rate (first 30 min) Maximum Infusion Rate in New Patients** (as tolerated) Maximum Infusion Rate in Experienced Patients*** (as tolerated)
Treatment of Primary Humoral Immunodeficiency (PI)*
300 to 600 mg/kg body weight (3-6 mL/kg) administered every 3 to 4 weeks 1 mg/kg/min
(0.01 mL/kg/min)
8 mg/kg/min
(0.08 mL/kg/min)
12 or 14 mg/kg/min
(0.12 or 0.14 mL/kg/min)
Treatment of Chronic Immune Thrombocytopenia (ITP)
2 g/kg, divided into two daily doses of 1 g/kg (10 mL/kg) given on two consecutive days 1 mg/kg/min
(0.01 mL/kg/min)
8 mg/kg/min
(0.08 mL/kg/min)

*Significant differences in the half-life of IgG among patients with PI may necessitate the dose and frequency of immunoglobulin therapy to vary from patient to patient. Determine the proper dose and frequency by monitoring the clinical response. Adjust dose over time to achieve the desired trough levels of IgG and clinical responses.

**Patients receiving PANZYGA (or another IGIV) for the first time or more than 8 weeks since a prior treatment.

*** Experienced patients received greater than 3 (12 mg/kg/min) to 6 (14 mg/kg/min) infusions every 3-4 weeks.

Following the initial infusion, the infusion rate may be gradually increased every 15-30 minutes to a maximum of 14 mg/kg/min (0.14 mL/kg/min) in PI and to 8 mg/kg/min (0.08 mL/kg/min) in chronic ITP in adults, as tolerated. The recommended ramp-up for an infusion is 1, 2, 4, and 8 mg/kg/min (0.01, 0.02, 0.04, and 0.08 mL/kg/min) in new PI and ITP patients (i.e., patients who have not previously received any IGIV product), and 1, 4, 8, and 12 or 14 mg/kg/min (0.01, 0.04, 0.08, and 0.12 or 0.14 mL/kg/min) in experienced PI patients (i.e., patients who have previously received any IGIV product).

Measles Exposure

If a patient with primary humoral immunodeficiency has been exposed to measles, it may be prudent to administer an extra dose of IGIV as soon as possible and within 6 days of exposure. A dose of 400 mg/kg should provide a serum level > 240 mIU/mL of measles antibodies for at least two weeks.

If a patient with primary humoral immunodeficiency is at risk of future measles exposure and receives a dose of less than 530 mg/kg every 3-4 weeks, the dose should be increased to at least 530 mg/kg. This should provide a serum level of 240 mIU/mL of measles antibodies for at least 22 days after infusion.

2.2 Administration

  • Inspect parenteral products visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Do not use PANZYGA if it is turbid and/or if discoloration is observed. Using a needle, no larger than a 16-gauge needle, insert the needle only once within the stopper area (delineated by the raised ring for penetration). Penetrate the stopper perpendicularly to its plane and within the ring.
  • PANZYGA bottles may be pooled under aseptic conditions into sterile infusion bags. Infuse within 8 hours after pooling.
  • Administer at room or body temperature only by the intravenous route, using an in-line filter with pore size 0.2-200 microns.
  • Do not administer PANZYGA simultaneously with another intravenous preparation in the same infusion set, including immune globulin products from another manufacturer.
  • After administration, flush the infusion line with either normal saline or 5% dextrose in water.
  • Monitor the patient carefully throughout the infusion. Certain adverse drug reactions are related to the rate of infusion, and will disappear promptly after slowing or stopping the infusion. In such cases, after symptoms subside, resume the infusion at a lower rate. Ensure that patients with pre-existing renal insufficiency are not volume depleted. For patients at risk of renal dysfunction or thromboembolic events, administer PANZYGA at the minimum infusion rate practicable. Do not exceed 3.3 mg/kg/min (0.033 mL/kg/min). Discontinue if renal function deteriorates.

3 Dosage Forms And Strengths

Solution containing 10% IgG (100 mg/mL) (See How Supplied/Storage and Handling ( 16 )).

4 Contraindications

  • PANZYGA is contraindicated in patients who have a history of severe systemic hypersensitivity reactions, such as anaphylaxis, to human immunoglobulin.
  • PANZYGA is contraindicated in IgA-deficient patients with antibodies against IgA and history of hypersensitivity .

5.1 Hypersensitivity

Severe hypersensitivity reactions may occur (See Contraindications ( 4 )) . [ 1 ] In case of hypersensitivity, discontinue PANZYGA infusion immediately and institute appropriate treatment. Have epinephrine available for immediate treatment of severe acute hypersensitivity reactions.

PANZYGA contains trace amounts of IgA (average 100 µg/mL in a 10% solution). IgA-deficient patients with antibodies against IgA are at greater risk of developing severe hypersensitivity and anaphylactoid reactions when administered PANZYGA (See Contraindications ( 4 )) .

5.2 Renal Failure

Renal dysfunction, acute renal failure, osmotic nephropathy, and death may occur upon use of PANZYGA in predisposed patients.

Ensure that patients are not volume depleted prior to the initiation of the infusion of PANZYGA.

For patients at risk of renal dysfunction because of pre-existing renal insufficiency or predisposition to acute renal failure (such as individuals with diabetes mellitus, age greater than 65 years, volume depletion, sepsis, paraproteinemia, or those receiving known nephrotoxic drugs), administer PANZYGA at the minimum infusion rate practicable (See Boxed Warning, and Dosage and Administration ( 2 )).

Periodic monitoring of renal function tests and urine output is particularly important in patients judged to be at risk of developing acute renal failure. Assess renal function, including a measurement of blood urea nitrogen (BUN)/serum creatinine, prior to the initial infusion of PANZYGA and again at appropriate intervals thereafter. If renal function deteriorates, consider discontinuation of the product.

5.3 Hyperproteinemia, Increased Serum Viscosity And Hyponatremia

Hyperproteinemia, increased serum viscosity and hyponatremia may occur in patients receiving PANZYGA therapy. It is clinically critical to distinguish true hyponatremia from pseudohyponatremia related to hyperproteinemia with concomitant decreased calculated serum osmolality or elevated osmolar gap, because treatment aimed at decreasing serum free water in patients with pseudohyponatremia may lead to volume depletion, a further increase in serum viscosity and a higher risk of thromboembolic events.[ 2 ]

5.4 Thrombotic Events

Thrombosis may occur following treatment with immune globulin products, including PANZYGA. Risk factors 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.

Consider baseline assessment of blood viscosity in patients at risk for hyperviscosity, including those with cryoglobulins, fasting chylomicronemia / markedly high triacylglycerols (triglycerides), or monoclonal gammopathies. For patients at risk of thrombotic events, administer PANZYGA 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.[ 3-5 ] (See BOXED WARNING, DOSAGE and ADMINSTRATION [ 2.3 ], PATIENT COUNSELING INFORMATION [ 17 ])

5.5 Aseptic Meningitis Syndrome

Aseptic meningitis syndrome (AMS) may occur with PANZYGA treatment. Discontinuation of treatment has resulted in remission of AMS within several days without sequelae. The syndrome usually begins within several hours to two days following infusion with PANZYGA. It is characterized by symptoms and signs including severe headache, nuchal rigidity, drowsiness, fever, photophobia, painful eye movements, nausea, and vomiting. Cerebrospinal fluid (CSF) studies frequently reveal pleocytosis up to several thousand cells per cubic millimeter, predominantly from the granulocytic series, and elevated protein levels up to several hundred mg/dl, but negative culture results. Conduct a thorough neurological examination in patients exhibiting such symptoms and signs, including CSF studies, to rule out other causes of meningitis. Patients with a history of migraine may be more susceptible.[ 6 ]

AMS may occur more frequently following high doses (≥ 2 g/kg) and/or rapid infusion of IGIV.

5.6 Hemolysis

PANZYGA may contain 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 (DAT) (Coombs’ test) result and hemolysis. Delayed hemolytic anemia can develop subsequent to IGIV therapy due to enhanced RBC sequestration and acute hemolysis, consistent with intravascular hemolysis, has been reported. Cases of severe hemolysis-related renal dysfunction/failure or disseminated intravascular coagulation have occurred following infusion of IGIV.

The following risk factors may be associated with the development of hemolysis following IGIV administration: high doses (e.g., 2 g/kg or more), given either as a single administration or divided over several days, and non-O blood group.[ 7 ] Other individual patient factors, such as an underlying inflammatory state (as may be reflected by, for example, elevated C-reactive protein or erythrocyte sedimentation rate), have been hypothesized to increase the risk of hemolysis following administration of IGIV [ 8 ], but their role is uncertain. Hemolysis has been reported following administration of IGIV for a variety of indications, including ITP.

Closely monitor patients for clinical signs and symptoms of hemolysis, particularly patients with risk factors noted above. Consider appropriate laboratory testing in higher risk patients, including measurement of hemoglobin or hematocrit prior to infusion and within approximately 36 to 96 hours post-infusion. If clinical signs and symptoms of hemolysis or a significant drop in hemoglobin or hematocrit have been observed, perform confirmatory laboratory testing, including direct antiglobulin test. If transfusion is indicated for patients who develop hemolysis with clinically compromising anemia after receiving IGIV, perform adequate cross-matching to avoid exacerbating on-going hemolysis.

5.8 Hypertension

Elevations of systolic blood pressure to 180 mm Hg or more and/or of diastolic blood pressure to more than 120 mm Hg (hypertensive urgency) can be observed during and/or shortly following infusion of IVIG. Such elevations are reported more often among patients with a history of hypertension. Check patients for a history of hypertension and current antihypertensive medication use. Monitor blood pressure prior to, during, and following PANZYGA infusion.

5.9 Volume Overload

Carefully consider the relative risks and benefits before prescribing the high dose regimen (for chronic ITP) in patients at increased risk of volume overload.

5.10 Transmission Of Infectious Agents

Because PANZYGA is made from human blood, it may carry a risk of transmitting infectious agents, e.g., viruses and theoretically, the variant Creutzfeldt-Jakob disease and Creutzfeldt-Jakob disease (CJD) agent. The risk of infectious agent transmission has been reduced by screening plasma donors and by including virus inactivation/removal steps in the manufacturing process of PANZYGA. Report all infections thought by a physician or other healthcare provider to have been possibly transmitted by this product to Pfizer Inc. at 1-800-438-1985. Discuss the risks and benefits of PANZYGA with the patient before prescribing or administering this product.

5.11 Monitoring Laboratory Tests

  • After infusion of immunoglobulin, the transitory rise of the 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. Clinically assess patients with known renal dysfunction, diabetes mellitus, age greater than 65 years, volume depletion, sepsis, paraproteinemia, or those receiving nephrotic agents, and monitor as appropriate (BUN; serum creatinine, urine output) during therapy with PANZYGA.
  • Consider baseline assessment of blood viscosity in patients at risk for hyperviscosity, including those with polycythemia, cryoglobulins, fasting chylomicronemia/markedly high triglycerides, or monoclonal gammopathies.
  • Consider measuring hemoglobin or hematocrit at baseline and approximately 36 to 96 hours post-infusion in patients at higher risk of hemolysis. If signs and/or symptoms of hemolysis are present after an infusion of PANZYGA, perform appropriate laboratory testing for confirmation.
  • If TRALI is suspected, perform appropriate tests for the presence of anti-neutrophil antibodies in both the product and patient’s serum.

6 Adverse Reactions

PI: The most common adverse reactions observed at a rate of more than 5% in subjects in clinical trials were: headache, abdominal pain, fever, nausea, and fatigue.

Chronic ITP in adults: The most common adverse reactions observed at a rate of more than 5% in subjects in clinical trials were: headache, fever, nausea, vomiting, dizziness, and anemia.

The most serious adverse reaction observed with PANZYGA treatment during clinical trials was an aseptic meningitis in one subject.

6.1 Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a product cannot be directly compared to rates in the clinical trials of another product and may not reflect the rates observed in clinical practice.

Treatment of Primary Humoral Immunodeficiency (PI)

In a prospective, open-label, single-arm, multicenter study in 51 children and adults with PI, subjects received PANZYGA at a dose between 200 to 800 mg/kg body weight every 3 or 4 weeks. Subjects participated in the study for a mean of 360 days. Infusions were initiated at a rate of 1 mg/kg/minute for the first 30 minutes, and, if tolerated, could be advanced to a maximum tolerated rate not exceeding 8 mg/kg/minute. The mean age of subjects was 26.8 years (range: 2 to 65 years).

This study was followed by an extension study that evaluated the safety of PANZYGA administered at higher infusion rates in 21 subjects that successfully had completed the first study. Nineteen of the 21 enrolled patients received PANZYGA up to the maximum allowed infusion rate of 14 mg/kg/minute.

In the study in PI, infusion-related adverse events (during or within 72 hours after the end of infusion) were reported in 16 patients (76%) enrolled in the 3-weeks treatment schedule and in 22 patients (73%) in the 4-weeks treatment schedule. Overall, 38 infusions (5%) had at least one adverse event considered related to study medication: 5 infusions (3%) in children, 4 infusions in adolescents (2%), and 29 infusions (8%) in adults. Study medication-related (possible or probable) infusion-related adverse reactions were associated with 35 infusions (5%) (overall); study medication-related headache was noted in 21 infusions (3%).

Headache 11 (22%)
Abdominal pain (upper) 7 (14%)
Fever 7 (14%)
Nausea 5 (10%)
Sinusitis 4 (8%)
Fatigue 3 (6%)
Bronchitis 3 (6%)

* Any infusional and any study medication related adverse events.

Treatment of Chronic Immune Thrombocytopenia (ITP) in Adults

In a prospective, open-label, single-arm, multicenter study, 40 adult subjects with chronic ITP received PANZYGA at a dose of 2 g/kg, administered daily as 1 g/kg intravenous infusions on 2 consecutive days. 3/40 subjects did not receive a second infusion of PANZYGA due to infusion reactions, including chills, headache, fever and nausea. All subjects except 1 received at least 1 infusion with the highest rate of 8 mg/kg/minute. Pre-medication to alleviate potential adverse drug reactions was not allowed in the study.

There were 67 treatment emergent adverse events (TEAEs) reported in 24 (60%) subjects that were related to administration of PANZYGA. 55 of these adverse events ( 82%) were infusional adverse events that occurred within 72 hours after start of the infusion. Seven of these adverse events in 2 subjects were severe. These included headache, nausea, vomiting and chills.

When analyzed by infusion, infusion-related adverse events were reported in 33 of the 77 infusions (43%),

Table 2: Adverse Reactions* Occurring in more than 5% of Subjects with Chronic ITP in Adults

Adverse Reaction No. of Subjects with Adverse Reaction(percentage of subjects)
Headache 20 (50%)
Fever 9 (23%)
Nausea 7 (18%)
Vomiting 4 (10%)
Dizziness 4 (10%)
Anemia 4(10%)

* Any infusional and any study medication related adverse events.

One out of 40 subjects with ITP treated with PANZYGA developed aseptic meningitis on Day 2 of the infusion. This subject was managed with antibiotics and supportive care with recovery.

Baseline direct Coomb’s test was performed in 39/40 subjects that were treated with PANZYGA. 10/39 (26%) subjects subsequently developed positive Coomb’s test. One subject was not tested at baseline but had positive results on all 3 subsequent visits. Four of these subjects (10%) developed hemolytic anemia after receiving PANZYGA. These resolved spontaneously without any intervention.

6.2 Postmarketing Experience

Because postmarketing reporting of adverse reactions is voluntary and from a population of uncertain size, it is not always possible to reliably estimate the frequency of these reactions or establish a causal relationship to product exposure. The following adverse reactions have been identified during post-approval use of IGIV products. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or to establish a causal relationship to IGIV products:

Blood and lymphatic system disorders
Leucopenia, hemolysis, pancytopenia
Immune system disorders
Hypersensitivity (e.g., anaphylaxis), anaphylactic shock, anaphylactic reaction, anaphylactoid reaction, allergic reaction, angioedema, face edema

7 Drug Interactions

Clinical studies have not evaluated mixtures of PANZYGA with other drugs and intravenous solutions. It is recommended that PANZYGA is administered separately from other drugs or medications which the patient may be receiving. Do not mix the product.

Do not mix PANZYGA with IGIVs from other manufacturers.

Passively transferred antibodies in immunoglobulin preparations can confound the results of serological testing, e.g. false positive Treponema pallidum testing might occur.

Antibodies in PANZYGA may interfere with the response to live viral vaccines, such as measles, mumps, and rubella. Inform physicians of recent therapy with PANZYGA, so that administration of live viral vaccines, if indicated, can be appropriately delayed for 3 or more months from the time of PANZYGA administration.

8.1 Pregnancy

Risk Summary

No human data are available to indicate the presence or absence of drug-associated risk. Animal reproduction studies have not been conducted with PANZYGA. It is also not known whether PANZYGA 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. 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.

8.2 Lactation

Risk summary

No human data are available to indicate the presence or absence of drug-associated risk. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for PANZYGA and any potential adverse effects on the breastfed infant from PANZYGA or from the underlying maternal condition.

8.4 Pediatric Use

Treatment of Primary Humoral Immunodeficiency (PI)

PANZYGA was evaluated in 25 pediatric subjects (age range: 2-15 years). Twenty-five percent of PI subjects exposed to PANZYGA were children (between 2 and 12 years of age). Pharmacokinetics, efficacy and safety were similar to those in adults. No specific dose requirements were necessary to achieve the targeted serum IgG levels in the pediatric subjects.

Treatment of Immune Thrombocytopenia (ITP) in children

The safety and effectiveness of PANZYGA have not been established in pediatric patients with ITP.

8.5 Geriatric Use

Clinical studies of PANZYGA did not include sufficient numbers of subjects older than 65 years to determine whether they respond differently from younger subjects. Patients older than 65 years of age may be at increased risk for developing adverse reactions such as thromboembolic events and acute renal failure (See Boxed Warnings and Thrombotic Events ( 5.4 ) and Renal Failure ( 5.2 ) . Do not exceed recommended doses in this population, and apply the minimum practicable infusion rate.

10 Overdosage

With intravenous administration, overdose may lead to fluid overload and hyperviscosity. Patients at risk of complications of fluid overload and hyperviscosity include elderly patients and those with cardiac or renal impairment.

11 Description

Immune Globulin Intravenous (Human), PANZYGA, is a solvent/detergent (S/D)-treated, sterile preparation of highly purified immunoglobulin G (IgG) derived from large pools of human plasma. PANZYGA is a solution for infusion to be administered intravenously.

This preparation contains approximately 100 mg of protein per mL (10%), of which not less than 96% is normal human immunoglobulin G. PANZYGA contains not more than 3% aggregates, not less than 90% monomers and dimers, and not more than 3% fragments. On average, the product contains 100 µg/mL of IgA, and lower amounts of IgM.

PANZYGA contains only trace amounts of sodium, and the pH is between 4.5 and 5.0. The osmolality is in the range of 240-310 mosmol/kg.

The manufacturing process for PANZYGA isolates IgG without additional chemical or enzymatic modification, and the Fc portion is maintained intact. PANZYGA contains the IgG antibody activities present in the donor population. IgG subclasses are fully represented with the following approximate percents of total IgG: IgG 1 is 65%, IgG 2 is 28%, IgG 3 is 3% and IgG 4 is 4%.

PANZYGA contains a broad spectrum of IgG antibodies against bacterial and viral agents that are capable of opsonization and neutralization of microbes and toxins. PANZYGA contains glycine (15.0-19.5 mg/mL), but no preservatives or sucrose.

All units of human plasma used in the manufacture of PANZYGA are provided by FDA-approved blood and plasma establishments, and are tested by FDA-licensed serological tests for HBsAg, antibodies to HCV and HIV and Nucleic Acid Test (NAT) for HCV and HIV1 and found to be non-reactive (negative).

The product is manufactured by the cold ethanol fractionation process followed by purification methodologies, as well as S/D treatment and nanofiltration (20 nm). The S/D mixture used is composed of tri-n-butyl phosphate (TNBP, solvent) and Triton X-100 (Octoxynol, detergent). The PANZYGA manufacturing process shows significant viral reduction and inactivation, demonstrated by in vitro infectivity studies (Table 3). The virus safety of PANZYGA is achieved through a combination of various process steps, including S/D treatment, ion-exchange chromatography, and nanofiltration (20 nm).

Table 3 shows the virus clearance during the manufacturing process for PANZYGA, expressed as the mean log 10 reduction factor (LRF).

Additionally, the manufacturing process was investigated for its capacity to decrease the infectivity of an experimental agent of transmissible spongiform encephalopathy (TSE), considered as a model for the vCJD and CJD agents. [ 10 ]

Several of the individual production steps in the PANZYGA manufacturing process were shown to decrease TSE infectivity of that experimental model agent. TSE reduction steps include ion-exchange chromatography and nanofiltration, which together give a total of at least 10.4 log10 decrease of infectivity. These studies provide reasonable assurance that low levels of CJD/vCJD agent infectivity, if present in the starting material, would be removed.

12.1 Mechanism Of Action

Treatment of Primary Humoral Immunodeficiency (PI)

PANZYGA supplies a broad spectrum of opsonic and neutralizing IgG antibodies against bacteria or their toxins. The mechanism of action in PI has not been fully elucidated.

Treatment of Chronic Immune Thrombocytopenia (ITP) in Adults

The mechanism of action of immunoglobulins in the treatment of chronic ITP in adults has not been fully elucidated.

12.2 Pharmacodynamics

PANZYGA contains mainly immunoglobulin G (IgG) with a broad spectrum of antibodies against various infectious agents reflecting the IgG activity found in the donor population. PANZYGA which is prepared from pooled material from not less than 1000 donors, has an IgG subclass distribution similar to that of native human plasma. Adequate doses of IGIV can restore abnormally low IgG level to the normal range. Standard pharmacodynamic studies were not performed.

12.3 Pharmacokinetics

Treatment of Primary Humoral Immunodeficiency (PI)

In the PI study, 50 pediatric and adult subjects underwent pharmacokinetic assessments. Subjects received infusions of PANZYGA (200 to 800 mg/kg body weight) every 3 or 4 weeks for 12 months. Blood samples for PK study were collected between the 7 th and 9 th PANZYGA infusion, depending on the individual treatment schedule.

Table 4a and 4b summarize the pharmacokinetic parameters of PANZYGA, based on serum concentrations of total IgG, in subjects receiving infusions every 3, or 4 weeks, respectively.

Treatment of Chronic Immune Thrombocytopenia (ITP) in Adults

Pharmacokinetic studies with PANZYGA have not been performed in patients with chronic ITP in adults.

13.1 Carcinogenesis, Mutagenesis, Impairment Of Fertility

No animal studies were conducted on carcinogenesis, mutagenesis, or impairment of fertility with PANZYGA.

13.2 Animal Toxicology And/Or Pharmacology

Several standard nonclinical proof-of-concept and safety studies were performed with PANZYGA in animals. These included acute toxicity, pharmacokinetic, local tolerance, and safety pharmacology studies. PANZYGA. There were no adverse effects attributed to PANZYGA in the animal studies.

TNBP and Octoxynol-9 may be found in PANZYGA in trace amounts. In single- and repeated-dose toxicity studies in animals, these impurities caused no adverse effects when administered (alone or in combination) at doses multiple times higher than the equivalent human dose. A mixture of these compounds did not show teratogenic effects when administered to pregnant rabbits and rats during organogenesis.

14.1 Treatment Of Primary Humoral Immunodeficiency (Pi)

Study 1: In a prospective, open-label, single-arm, multicenter study in 51 children and adults with PI, subjects received PANZYGA at a dose between 200 to 800 mg/kg body weight every 3 or 4 weeks. Subjects participated in the study for a mean of 360 days. Infusions were initiated at a rate of 1 mg/kg/min for the first 30 minutes, and, if tolerated, could be advanced to a maximum tolerated rate not exceeding 8 mg/kg/min. The mean age of subjects was 26.8 years (range: 2 to 65 years).

The primary efficacy endpoint was the number of episodes of serious bacterial infections per patient per year. Serious infection included pneumonia, bacteremia or sepsis, osteomyelitis/septic arthritis, visceral abscesses, or bacterial meningitis. Secondary efficacy variables included: occurrence of any infection of any kind or seriousness; time to resolution of infections; use of antibiotics; the number of days of work/school missed; the number and days of hospitalizations; and the number of episodes of fever.

For the primary endpoint, the observed rate was 0.08 serious bacterial infections per patient per year (4 infections over 50.2 patient-years).

Only 1 adult patient was hospitalized due to an infection for 4 days (overall rate of days in hospital per person-year: 0.080). Episodes of fever were observed for less than 25% of all patients. The mean resolution time was 14 days for serious bacterial infections and 18 days for other infections. Approximately 50% of all patients missed at least 1 day of work or school due to infections, with an annual rate of less than 4 days/person-year.

Table 5 summarizes the efficacy results for all 51 subjects.

Throughout the entire study, the serum IgG trough levels were nearly constant for both treatment schedules and were above the required trough levels of about 5-6 g/L. The calculated pharmacokinetic parameters showed that the minimum concentration of IgG was at least 6.8 g/L for both treatment intervals.

14.2 Treatment Of Chronic Immune Thrombocytopenia (Itp) In Adults

A prospective, open-label, single-arm, multicenter study assessed the efficacy, safety, and tolerability of PANZYGA in 40 subjects with chronic ITP and a platelet count of 20 x 10 9 /L or less. Subjects ranged in age from 18 to 72 years (median: 32 years); 43% were female and 57% were male. Ninety percent of the subjects were Caucasian and 10% were Asian.

Subjects received a 2 g/kg dose of PANZYGA administered as two daily 1 g/kg intravenous doses, given on 2 consecutive days. All but one patient received the maximum infusion rate of 8 mg/kg/minute, starting at 1 mg/kg/minute. Platelet counts were measured on Days 1 to 8, 15, and 22.

The study was designed to determine the response rate, defined as the percentage of subjects with an increase in platelet count to at least 50 x 10 9 /L within 7 days after the first infusion (responders). Additionally, maximum platelet count, the time to reach a platelet count of at least 50 x 10 9 /L within the first 7 days, the duration of that response (i.e., the number of days the platelet count remained in excess of 50 x 10 9 /L), and the regression of hemorrhages in subjects who had bleeding at baseline were observed.

Of the 36 subjects in the full analysis set, 29 (81%: 95% CI: 64%- 92%).) responded to PANZYGA with a rise in platelet count to at least 50 x 10 9 /L within 7 days after the first infusion. The lower bound of the overall 95% confidence interval for the response rate in all 36 subjects (64%) is above the predefined response rate of 60%.

Table 6 shows the median and mean of the maximum platelet count.

Of the 36 subjects, 23 (64%) subjects had bleeding at baseline. Bleeding was minor in 14 subjects (39%), mild in 2 subjects (6%) and moderate in 7 subjects (19%). On Day 7, only 14% of subjects were bleeding (5/36). Persistent bleeding was mild in 1 and minor in 2 subjects. Information regarding bleeding resolution was missing in 2 subjects with moderate bleeding.
