CINRYZE (C1 esterase inhibitor [human]) (Freeze-Dried powder for Reconstitution) is a sterile, stable,
lyophilized preparation of C1 esterase inhibitor derived from human plasma. CINRYZE is manufactured
from human plasma purified by a combination of filtration and chromatographic procedures. The
specific activity of CINRYZE is 4.0 – 9.0 units/mg protein. The purity is ≥ 90% human C1 esterase
inhibitor. Following reconstitution with 5 mL of Sterile Water for Injection, USP, each vial contains
approximately 500 units of functionally active C1 esterase inhibitor, pH 6.6 - 7.4, and an osmolality
between 200 – 400 mosmol/kg. One Unit (U) of CINRYZE corresponds to the mean quantity of C1
esterase inhibitor present in 1 mL of normal fresh plasma.
CINRYZE, when reconstituted with 5 mL of Sterile Water for Injection, USP contains the following
excipients: 4.1 mg/mL sodium chloride, 21 mg/mL sucrose, 2.6 mg/mL trisodium citrate, 2.0 mg/mL LValine,
1.2 mg/mL L-Alanine, and 4.5 mg/mL L-Threonine.
The following manufacturing steps are designed to reduce the risk of viral transmission:
Screening donors at U.S. licensed blood collection centers to rule out infection with Human
Immunodeficiency Virus (HIV-1/HIV-2), Hepatitis B Virus, or Hepatitis C Virus.
Testing plasma pools by in-process NAT for parvovirus B19 via minipool testing and the limit of
B19 in the manufacturing pool is set not to exceed 104 IU of B19 DNA per mL.
Use of two independent viral reduction steps in the manufacture of CINRYZE: pasteurization (heat
treatment at 60°C for 10 hours in solution with stabilizers) and nanofiltration through two sequential
15 nm filters.
These viral reduction steps, along with a step in the manufacturing process, PEG precipitation, have
been validated in a series of in vitro experiments for their capacity to inactivate/remove a wide range of
viruses of diverse physicochemical characteristics including: Human Immunodeficiency Virus (HIV),
Hepatitis A Virus (HAV), and the following model viruses: Bovine Viral Diarrhea Virus (BVDV) as a
model virus for HCV, Canine Parvovirus (CPV) as a model virus for Parvovirus B19, Pseudorabies
Virus (PRV) as a model virus for large enveloped DNA viruses (e.g. herpes virus). Total mean log
reductions are shown in Table 4.

Table 1 Routine Prophylaxis Dosing
against HAE attacks
every 3 or 4 days
Instructions For Use
The procedures below are provided as general guidelines for the reconstitution and administration of
CINRYZE. Use either the Mix2Vial® transfer device or a commercially available double-ended needle.
Always work on a clean surface and wash your hands before performing the following procedures.
Reconstitution, product administration, and handling of the administration set and needles must be done
with caution. Percutaneous puncture with a needle contaminated with blood can transmit infectious
viruses including HIV (AIDS) and hepatitis. Obtain immediate medical attention if injury occurs. Place
needles in a sharps container after single use. Discard all equipment, including any reconstituted
CINRYZE in an appropriate container.
Preparation And Handling
Protect CINRYZE from light prior to reconstitution.
A silicone-free syringe is recommended for reconstitution and administration of CINRYZE.
Inspect the reconstituted product for particulate matter prior to administration; do not use if particles
are observed or if solution is turbid. The reconstituted solution is colorless to slightly blue.
Each vial of CINRYZE is for single use only. Promptly use any vial that has been entered and
discard partially used vials in accordance with biohazard procedures. CINRYZE contains no
Do not mix CINRYZE with other materials.
Do not use if frozen.
Do not use after expiration date.
Two vials of reconstituted CINRYZE are combined for a single dose. Sterile Water for Injection, USP,
is required and not supplied with CINRYZE.
Aseptic technique should be used during the reconstitution procedure.
Bring the CINRYZE (powder) and Sterile Water for Injection, USP (diluent) (not supplied) to room
temperature if refrigerated.
Remove caps from the CINRYZE and diluent vials.
Cleanse stoppers with an alcohol wipe or swab, and allow them to dry prior to use.
Remove protective covering from the top of the Mix2Vial transfer device package. Do not remove
the device from the package.
Note: Diluent vial must be accessed prior to the vial of CINRYZE to prevent loss of vacuum. Place
diluent on a flat surface and insert the blue end of the device into the diluent vial, pushing down until
the spike penetrates through the center of the diluent vial stopper and the device snaps in place
(Figure 1). The Mix2Vial transfer device must be positioned completely vertical prior to penetrating
the stopper closure.
Remove the plastic package and discard it (Figure 2). Take care not to touch the exposed end of the
Place vial of CINRYZE on a flat surface. Invert diluent vial containing 5 mL Sterile Water for
Injection, USP, and insert the clear end into the CINRYZE vial, pushing down until the spike
penetrates the rubber stopper and the device snaps into place. The Mix2Vial transfer device must be
positioned completely vertical prior to penetrating the stopper closure. The Sterile Water for
Injection, USP will automatically flow into the vial of CINRYZE (Figure 3), because the vacuum in
the vial will draw in the diluent. If there is no vacuum in the vial, do not use the product.
Gently swirl (do not shake) the CINRYZE vial until all powder is dissolved. Be sure that CINRYZE
is completely dissolved (Figure 4). Disconnect the Sterile Water for Injection, USP vial by turning it
counterclockwise (Figure 5). Do not remove the clear end of the Mix2Vial transfer device from the
vial of CINRYZE.
One vial of reconstituted CINRYZE contains 5 mL of C1 esterase inhibitor at a concentration of 100
Units/mL. Reconstitute two vials of CINRYZE for one dose. Repeat steps 1 to 9 above using an
additional package containing a Mix2Vial transfer device to reconstitute the second of two vials of
CINRYZE. Do not reuse the Mix2Vial transfer device. CINRYZE must be administered at room
temperature within 3 hours after reconstitution.
Two vials of reconstituted CINRYZE are combined for a single dose.
Use Aseptic Technique.
After reconstitution, the solution should be clear with no evidence of turbidity. Reconstituted
solution should be colorless to slightly blue. Do not use if solution is turbid or otherwise
Please refer to the illustrations in steps 7 to 9 included within the Patient Information Leaflet.
Utilizing a sterile, disposable 10 mL syringe, draw back the plunger to admit 5 mL air into the
Attach the syringe onto the top of the clear end of the Mix2Vial transfer device by turning it
Invert the vial and inject air into the solution and then slowly withdraw the reconstituted CINRYZE
into the syringe.
Detach the syringe from the vial by turning it counterclockwise and releasing it from the clear end
of the Mix2Vial transfer device.
Using the same syringe, repeat steps 3to 6 with a second vial of CINRYZE to make the complete
dose. CINRYZE should be administered promptly after preparation in the syringe and should not be
used if particles are observed or if the solution is turbid.
Attach a suitable needle or infusion set with winged adapter, and inject intravenously. As a
guideline, administer 1,000 Units (reconstituted in 10 mL) of CINRYZE by intravenous injection at a
rate of 1 mL per minute over 10 minutes. (see DOSAGE AND ADMINISTRATION) Please refer
to the illustration in step 3 of the self administration section within the Patient Information Leaflet.
Dispose of all unused solution, the empty vial(s), and the used needles and syringes in an appropriate
container for throwing away waste that might hurt others if not handled properly.

Side Effects & Drug Interactions
The only serious adverse reaction observed in clinical studies of CINRYZE was cerebrovascular
The most common adverse reactions observed were headache, nausea, rash, and vomiting.
Because CINRYZE is a therapeutic protein, there is potential for immunogenicity. Using a validated
assay there was no evidence of antibody development following administration of CINRYZE. The
detection of antibody formation is highly dependent on the sensitivity and specificity of the assay.
Additionally, the observed incidence of anti-C1 Esterase Inhibitor antibody positivity in an assay may be
influenced by several factors including assay methodology, sample handling, timing of sample
collection, concomitant medications, and underlying disease. For these reasons, comparison of the
incidence of antibody development across products cannot be made.
Clinical Trials Experience
Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in
the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may
not reflect the rates observed in practice.
Twenty-four subjects were evaluated in the randomized, placebo-controlled, crossover, routine
There were no serious adverse reactions in the randomized, placebo-controlled, crossover, routine
Adverse reactions in the randomized, placebo-controlled, crossover, routine prophylaxis trial (n=24)
that occurred in at least two subjects (≥8%) receiving CINRYZE are given in the following table:

(N = 24)
In an open-label follow-on trial, 146 patients received a median of 243.5 days of CINRYZE (maximum =
959 days). The most common adverse reaction observed was headache. No patients were discontinued
due to an adverse reaction.
Adverse reactions in the open-label follow-on trial (n=146) that occurred in at least three subjects
(≥2%) receiving CINRYZE, are given in the following table:

Catheter Site Pain
More than 14,000 doses of CINRYZE have been administered to over 260 different patients in all
completed, controlled and open-label clinical studies. All patients who were evaluated were found
negative for seroconversion to parvovirus B19, Hepatitis B, Hepatitis C and HIV. (See
Transmissible Infectious Agents)
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.
Postmarketing adverse reactions include local infusion site reactions (including inflammation or
hematoma at the infusion site) and hypersensitivity.
Postmarketing thromboembolic events have been reported, including catheter-related and deep venous
thromboses, transient ischemic attack, and stroke.
No drug interaction studies have been conducted.
Warnings & Precautions
Included as part of the "PRECAUTIONS" Section
Severe hypersensitivity reactions may occur. The signs and symptoms of hypersensitivity reactions may
include the appearance of hives, urticaria, tightness of the chest, wheezing, hypotension and/or
anaphylaxis experienced during or after injection of CINRYZE.
Consider treatment methods carefully, because hypersensitivity reactions may have symptoms similar to
In case of hypersensitivity, discontinue CINRYZE infusion and institute appropriate treatment. Have
epinephrine immediately available for treatment of acute severe hypersensitivity reaction. (See Patient Counseling Information)
Serious arterial and venous thromboembolic (TE) events have been reported at the recommended dose
of C1 Esterase Inhibitor (Human) products, including CINRYZE, following administration in patients
with HAE. Risk factors may include presence of an indwelling venous catheter/access device, prior
history of thrombosis, underlying atherosclerosis, use of oral contraceptives, certain androgens,
morbid obesity, and immobility. Benefits of CINRYZE for routine prophylaxis of HAE attacks should
be weighed against the risks of TE events in patients with underlying risk factors. Monitor patients with
known risk factors for TE events during and after CINRYZE administration.
TE events have been reported following administration of a C1 Esterase Inhibitor (Human) product
when used off-label at higher than labeled doses2,3. (see Animal Pharmacology)
In an open-label trial further investigating the use of CINRYZE for prevention (n=146) of HAE attacks,
5 serious thromboembolic events (including myocardial infarction, deep vein thrombosis, pulmonary
embolism and 2 events of cerebrovascular accident) occurred. Subjects had underlying risk factors for
Transmissible Infectious Agents
Because CINRYZE is made from human blood, it may carry a risk of transmitting infectious agents, e.g.
viruses, and, theoretically, the Creutzfeldt-Jakob disease (CJD) agent . ALL infections thought by a
physician possibly to have been transmitted by CINRYZE should be reported by the physician or other
healthcare provider to Shire Medical Information. [1-800-828-2088]. The physician should discuss the
risks and benefits of this product with the patient, before prescribing or administering it to the patient.
(See PATIENT INFORMATION)
Patient Counseling Information
See FDA-approved patient labeling (PATIENT INFORMATION).
Inform patients to immediately report the following to their physician:
Signs of allergic-type hypersensitivity reactions including hives (itchy white elevated patches),
tightness of the chest, wheezing, hypotension and anaphylaxis [5.1]. Advise patients to
discontinue use of CINRYZE and contact their physicians if these symptoms occur.
Signs of a thromboembolic event including pain and/or swelling of an arm or leg with warmth
over the affected area, discoloration of an arm or leg, unexplained shortness of breath, chest
pain or discomfort that worsens on deep breathing, unexplained rapid pulse, numbness or
weakness on one side of the body.
Advise patients with known risk factors for thromboembolic events that they may be at increased risk
for these events.
Advise female patients to notify their physician if they become pregnant or intend to become
pregnant during their routine prevention with CINRYZE.
Advise patients to notify their physician if they are breastfeeding or plan to breastfeed.
Based on their current regimen, advise patients to bring an adequate supply of CINRYZE for routine
prevention when traveling.
Advise patient that, because CINRYZE is made from human blood, it may carry a risk of transmitting
infectious agents, e.g. viruses, and, theoretically, the Creutzfeldt-Jakob disease (CJD) agent [5.3,
11]. The risk of transmitting disease has been reduced, but not eliminated, by carefully selecting
blood donors, testing donors for infections, and inactivating or removing most viruses during the

Carcinogenesis, Mutagenesis, Impairment Of Fertility
No animal studies have been completed to evaluate the effects of CINRYZE on carcinogenesis,
mutagenesis, and impairment of fertility.
Use In Specific Populations
Background risk (general population)
A review of available data suggests that major birth defects occur in 2-4% of the U.S. general
population and that miscarriage occurs in 15-20% of clinically recognized pregnancies, regardless of
Risk in CINRYZE patients
No adequate and well-controlled studies of CINRYZE were conducted in pregnant women. It is not
known whether CINRYZE can cause fetal harm when administered to a pregnant woman or can affect
reproduction capacity. CINRYZE should be given to a pregnant woman only if clearly needed.
The safety and effectiveness of CINRYZE administration prior to or during labor and delivery have not
been established. Use only if clearly needed.
In an embryofetal development study (C1 inhibitor administered during the period of organogenesis) in
rats, there was no maternal or fetal toxicity at doses up to 400 Units/kg/day that provided an exposure
similar to that in humans after a 1000 Unit dose.
It is not known whether CINRYZE is excreted in human milk. Because many drugs are excreted in human
milk, caution should be exercised when CINRYZE is administered to a nursing woman.
The safety and effectiveness of CINRYZE have not been established in neonates, infants, or children.
Three of the 24 subjects in the randomized, placebo-controlled, crossover, routine prophylaxis trial,
were under the age of 18 years (9, 14, and 16 years of age).
The randomized, placebo-controlled, crossover, routine prophylaxis trial did not include sufficient
numbers of subjects 65 years of age and older to determine whether they respond differently from

Overdosage & Contraindications
The maximum dose administered in clinical studies was 4000 Units given over approximately 5 hours
(an average dose of 57 Units/kg) and 9000 Units given over a 7 day period. There have been no
overdosages of CINRYZE reported during clinical studies.
CINRYZE is contraindicated in patients who have manifested life-threatening immediate hypersensitivity
reactions, including anaphylaxis to the product.
Mechanism Of Action
C1 inhibitor is a normal constituent of human blood and is one of the serine proteinase inhibitors
(serpins). The primary function of C1 inhibitor is to regulate the activation of the complement and
intrinsic coagulation (contact system) pathway. C1 inhibitor also regulates the fibrinolytic system.
Regulation of these systems is performed through the formation of complexes between the proteinases
and the inhibitor, resulting in inactivation of both and consumption of the C1 inhibitor.
HAE patients have low levels of endogenous or functional C1 inhibitor. Although the events that induce
attacks of angioedema in HAE patients are not well defined, it is thought by some that increased
vascular permeability and the clinical manifestation of HAE attacks are primarily mediated through
contact system activation. Suppression of contact system activation by C1 inhibitor through the
inactivation of plasma kallikrein and factor XIIa is thought to modulate this vascular permeability by
preventing the generation of bradykinin1. Administration of CINRYZE increases plasma levels of C1
In clinical studies, the intravenous administration of CINRYZE demonstrated an increase in plasma
levels of C1 inhibitor within approximately one hour or less of administration.
Biological activity of CINRYZE was shown in 35 subjects by the subsequent increase in plasma C4
levels from an average of C4 8.1 mg/mL at baseline to C4 8.6 mg/mL 12 hours after infusion of
A randomized, parallel group, open-label pharmacokinetics (PK) study of CINRYZE was performed in
patients with non-symptomatic hereditary angioedema (HAE). The patients received either a single dose
of 1,000 Units or 1,000 Units followed by a second 1,000 Units 60 minutes later. The PK results for
functional C1 inhibitor are presented the following table:

The maximum plasma concentrations (Cmax) and area under the plasma concentration-time curve (AUC)
increased from the single to double dose, although the increase was not dose proportional. The mean
half-lives of CINRYZE were 56 hours (range 11 to 108 hours) for a single dose and 62 hours (range 16
to 152 hours) for the double dose.
Studies have not been conducted to evaluate the PK of CINRYZE in special patient populations
identified by gender, race, age (pediatric or geriatric), or the presence of renal or hepatic impairment.
Animal Toxicology And/Or Pharmacology
Acute toxicity of CINRYZE was studied in a combined acute toxicity and 7-day repeat dose/ dose range
finding (DRF) study in Sprague Dawley rats followed by a pivotal 14-day repeat dose study. The acute
and 14-day repeat dose toxicity studies were performed with intravenous administration of CINRYZE at
dose levels of 1, 7 and 28 times normal dose. No signs of toxicity were observed in the single dose or
repeat dose studies. Repeat dosing in the rat resulted in an antibody response between days 1 and 14 that
was not characterized for neutralizing activity. However, there was no change in the functional activity
of CINRYZE over the dosing period.
In vitro and in vivo animal thrombogenicity studies with CINRYZE showed a potential for clot formation
when CINRYZE was administered at doses 14 times the recommended clinical dose (greater than
200U/kg). Thrombotic events have been reported with another C1 esterase inhibitor product when used
off-label at high doses.2 Animal studies have supported a concern about the risk of thrombosis from
intravenous administration of C1 esterase inhibitor products.3 (see Thromboembolic Events in
WARNINGS AND PRECAUTIONS).
The safety and efficacy of CINRYZE prophylaxis therapy to reduce the incidence, severity, and
duration of HAE attacks was demonstrated in a single randomized, double blind, placebo controlled
multi-center cross-over study of 24 patients. Patients were screened to confirm a diagnosis of HAE and
a history of at least two HAE attacks per month. 24 patients (mean age 38.1 years with a range of 9 to 73
years) were randomized to one of two treatment groups: either CINRYZE prophylaxis for 12 weeks
followed by 12 weeks of placebo prophylaxis; or randomized to placebo prophylaxis for 12 weeks
followed by 12 weeks of CINRYZE prophylaxis. Two subjects dropped out (one in each arm); 22
patients crossed over into period 2 and were included in the efficacy analysis. Patients were given
blinded injections (CINRYZE or placebo) every 3 to 4 days, approximately 2 times per week. Patients
recorded all angioedema symptoms daily. An attack was defined as the subject-reported indication of
swelling at any location following a report of no swelling on the previous day.
The efficacy determination was based on the number of attacks during the 12 week period while
receiving CINRYZE as compared to the number of attacks during the placebo treatment period. The
effectiveness of C1 esterase inhibitor prophylaxis in reducing the number of HAE attacks was variable
among the subjects as shown in table 6:

What is CINRYZE?
CINRYZE is an injectable medicine that is used to help prevent swelling and/or painful attacks in
teenagers and adults with Hereditary Angioedema (HAE). HAE is caused by the decreased functioning
of a protein called C1 esterase inhibitor, that is present in your blood and helps control inflammation
(swelling) and parts of the immune system. CINRYZE contains C1 esterase inhibitor. Before you can
inject CINRYZE into your vein (intravenous injection), you must dissolve the CINRYZE powder using
Sterile Water for Injection, USP. You can get supplies, including Sterile Water for Injection, USP from

The Mix2Vial transfer device must be positioned completely upright before penetrating the rubber
stopper. The Sterile Water for Injection, USP, will automatically flow into the vial of CINRYZE
because the vacuum in the vial will draw the Sterile Water for Injection, USP, into the vial of
CINRYZE. If this does not happen, do not use the product.
Once all the Sterile Water for Injection, USP, is in the CINRYZE vial, gently swirl (do not shake) the
vial of CINRYZE until all the powder is dissolved. Disconnect the Sterile Water for Injection, USP
vial by turning it counterclockwise. Do not remove the clear end of the Mix2Vial transfer device
from the vial of CINRYZE.
Look at the final solution before using it to make sure that CINRYZE is completely dissolved. The
solution should be clear with no evidence of cloudiness. Reconstituted solution should be colorless
to slightly blue. Do not use if solution is cloudy or otherwise discolored and call Shire Medical

One vial of dissolved CINRYZE contains 5 mL of C1 esterase inhibitor at a concentration of 100
Units/mL. Prepare two vials of CINRYZE for one dose. Repeat steps 1-6 using a new Mix2Vial
transfer device. Do not reuse the Mix2Vial transfer device. CINRYZE should be administered
within 3 hours of reconstitution.
Utilizing a sterile, disposable 10mL syringe, draw back the plunger to allow approximately 5mL of
air into the syringe. Use of a silicone-free syringe is recommended.
Attach the syringe onto the clear end of the Mix2Vial transfer device by turning it clockwise.
Turn the vial of CINRYZE upside down, inject air into the vial. Slowly pull as much dissolved
CINRYZE as possible into the syringe. While holding the vial upside down, detach the syringe from
the vial by turning it counterclockwise and releasing it from the Mix2Vial transfer device. Remove
any air bubbles by gently tapping the syringe with your finger and slowly pushing the air out of the
Repeat steps 7-9 above with a second vial of CINRYZE to make one complete dose of 10 mL.
Dispose of the vials with the Mix2Vial transfer device attached to them.
CINRYZE should be administered at room temperature promptly after preparation in the syringe.
SELF ADMINISTRATION (Intravenous Injection)
Your healthcare provider will teach you how to safely administer CINRYZE. It is important that
CINRYZE is injected directly into a superficial vein and not injected into surrounding tissues and not
injected into an artery. Once you learn how to self-administer, you can follow the instructions in this
Attach a needle or infusion set with a winged adapter to the syringe containing the dissolved
CINRYZE solution. Fill the tubing with dissolved CINRYZE by gently pushing the plunger of the
syringe. Be careful not to spill the dissolved CINRYZE. This process replaces the air in the tubing
with dissolved CINRYZE.
Apply a tourniquet and prepare the injection site by wiping the skin well with an alcohol swab.
As instructed by your healthcare provider:
Insert the butterfly needle of the infusion set tubing into your vein.
Remove the tourniquet.
Make sure that the needle is in a vein.
Inject the dissolved CINRYZE product slowly over ten minutes (approximately 1mL/min).
After infusing CINRYZE, remove the infusion set and discard. Cover infusion site with an adhesive
bandage. The amount of drug product left in the infusion set will not affect your treatment. Dispose
of all unused solution, the empty vials, and the used needles and syringe in an appropriate container
used for throwing away waste that might hurt others if not handled properly.
It is a good idea to record the lot number from the CINRYZE vial label every time you use CINRYZE.
