One vial contains 2100 units of conestat alfa, corresponding to 2100 units per 14 ml after
reconstitution, or a concentration of 150 units/ml.
Conestat alfa is the recombinant analogue of the human C1 esterase inhibitor (rhC1INH) produced by
recombinant DNA technology in the milk of transgenic rabbits.
1 Unit of conestat alfa activity is defined as the equivalent of C1 esterase inhibiting activity present in
1 ml of pooled normal plasma.
For a full list of excipients, see section 6.1
3.
Powder for solution for injection.
White to off-white powder.
4.
Ruconest is indicated for treatment of acute angioedema attacks in adults with hereditary angioedema
(HAE) due to C1 esterase inhibitor deficiency.
Ruconest should be initiated under the guidance and supervision of a physician experienced in the
diagnosis and treatment of hereditary angioedema.
Ruconest should be administered by a healthcare professional.
Patients who have not previously received Ruconest should be tested for the presence of IgE
antibodies against rabbit epithelium (dander) prior to initiation of Ruconest (see section 4.4).
Posology
- Adults up to 84 kg body weight
One intravenous injection of 50 U/kg body weight.
- Adults of 84 kg body weight or greater
One intravenous injection of 4200 U (two vials).
In the majority of cases a single dose of Ruconest is sufficient to treat an acute angioedema attack.
In case of an insufficient clinical response, an additional dose (50 U/kg body weight up to 4200 U) can
be administered (see section 5.1).
Not more than two doses should be administered within 24 hours.
Dose calculation
Determine the patient’s body weight.
2
- Adults up to 84 kg body weight
For patients up to 84 kg calculate the volume required to be administered according to the formula
below:
Volume to be
administered (ml)
=
body weight (kg) times 50 (U/kg)
150 (U/ml)
=
body weight (kg)
3
- Adults of 84 kg body weight or greater
For patients of 84 kg or above the volume required to be administered is 28 ml, corresponding to
4200 U (2 vials).
Paediatric population
The safety and efficacy of Ruconest in children (age 0 to 12 years) has not yet been established.
Currently available data on adolescents (age 13 to 17 years) are described in section 5.1, but no
recommendation on a posology can be made.
Elderly (
≥
65 years old)
Data in patients older than 65 years are limited.
There is no rationale for patients older than 65 years to respond differently to Ruconest.
Renal impairment
No dose adjustment is necessary in patients with renal impairment since conestat alfa does not undergo
renal clearance.
Hepatic impairment
There is no clinical experience with Ruconest in patients with hepatic impairment. Hepatic impairment
may prolong the plasma half-life of conestat alfa, but this is not thought to be a clinical concern. No
recommendation on a dose adjustment can be made.
Method of Administration
For intravenous use.
For instructions on reconstitution of Ruconest before administration, see section 6.6.
The required volume of the reconstituted solution should be administered as a slow intravenous
injection over approximately 5 minutes.
Known or suspected allergy to rabbits (see section 4.4)
Hypersensitivity to the active substance or to any of the excipients
Conestat alfa is derived from milk of transgenic rabbits and contains traces of rabbit protein. Before
initiating treatment with Ruconest, patients should be tested for the presence of IgE antibodies against
rabbit allergens using a validated test for IgE antibodies against rabbit epithelium (dander) e.g.
ImmunoCap system, Phadia, Sweden. Only patients who have been shown to have negative results for
such a test, should be treated with Ruconest. IgE antibody testing should be repeated once a year or
after 10 treatments, whichever occurs first.
As with any intravenously administered protein product, hypersensitivity reactions cannot be
excluded.
Patients must be closely monitored and carefully observed for any symptoms of hypersensitivity
throughout the administration period. Patients should be informed of the early signs of
3
hypersensitivity reactions including hives, generalised urticaria, tightness of the chest, wheezing,
hypotension and anaphylaxis. If these symptoms occur after administration, they should alert their
physician.
In case of anaphylactic reactions or shock, emergency medical treatment should be administered.
Although cross-reactivity between cow milk and rabbit milk is considered unlikely, the possibility of
such a cross-reactivity in a patient who has evidence of clinical allergy to cow milk cannot be
excluded.
No drug-drug interaction studies have been performed.
Scientific literature indicates an interaction of tissue-type plasminogen activator (tPA) and C1INH
containing medicinal products
.
Ruconest should not be administered simultaneously with tPA.
Pregnancy and breast-feeding
There is no experience with the use of Ruconest in pregnant and breast-feeding women.
In one animal study reproductive toxicity was observed (see section 5.3). Ruconest is not
recommended for use during pregnancy or breast-feeding, unless the treating physician judges the
benefits to outweigh the possible risks.
Fertility
There are no data on the effects of Ruconest on male or female fertility.
Based on the known pharmacology and adverse reaction profile of Ruconest, effects on the ability to
drive and use machines are not expected. However headache or vertigo have been reported following
the use of Ruconest, but may also occur as a result of an attack of HAE. Patients should be advised not
to drive and use machines if they experience headache or vertigo.
The clinical experience supporting safety of Ruconest consists of 300 administrations
(83 administrations to healthy subjects or asymptomatic HAE patients and 217 administrations to
119 HAE patients). The table below lists all adverse reactions occurring within 7 days after treatment
with Ruconest, as reported in the six treatment studies.
Adverse reactions were usually mild to moderate in severity. The incidence of adverse reactions was
similar for all dose groups and did not increase upon repeated administrations.
The frequency of possible adverse reactions listed below is defined using the following convention:
Very common (≥1/10),
Common (≥1/100 to <1/10),
Uncommon (≥1/1,000 to <1/100),
Rare (≥1/10,000 to <1/1,000),
Very rare (<1/10,000),
Not known, frequency could not be estimated from the available data.

5.1
Pharmacodynamic properties
Pharmacotherapeutic group and ATC code: not yet assigned
The plasma protein C1INH is the main regulator of activation of the contact and complement systems
in vivo
. HAE patients have a heterozygous deficiency of the plasma protein C1INH. As a result they
may suffer from uncontrolled activation of contact and complement systems, with formation of
inflammatory mediators, which clinically becomes manifest as the occurrence of acute angioedema
attacks.
Conestat alfa, recombinant human complement component 1 (C1) esterase inhibitor (rhC1INH), is an
analogue of human C1INH and is obtained from the milk of rabbits expressing the gene encoding for
human C1INH. The amino acid sequence of conestat alfa is identical to that of endogenous C1INH.
C1INH exerts an inhibitory effect on several proteases (target proteases) of the contact and
complement systems. The effect of conestat alfa on the following target proteases was assessed
in
vitro
: activated C1s, kallikrein, factor XIIa and factor XIa. Inhibition kinetics were found to be
comparable with those observed for plasma-derived human C1INH.
The complement component (protein) C4, is a substrate for activated C1s. Patients with HAE have low
levels of C4 in the circulation. As for plasma-derived C1INH, the pharmacodynamic effects of
conestat alfa on C4 show dose-dependent restoration of complement homeostasis in HAE patients at a
plasma C1INH activity level greater than 0.7 U/ml, which is the lower limit of the normal range. In
HAE patients, Ruconest at a dose of 50 U/kg increases plasma C1INH activity level to greater than
0.7 U/ml for approximately 2 hours (see section 5.2).
The efficacy and safety of Ruconest as a treatment of acute angioedema attacks in patients with HAE
has been evaluated in two double blind randomized placebo controlled and four
open label clinical
studies. The doses evaluated in the clinical studies ranged from a single vial of 2100 U (corresponding
to 18-40 U/kg), to 50 and 100 U/kg. Efficacy of Ruconest as a treatment for acute angioedema attacks
was demonstrated by significantly shorter time to beginning of relief of symptoms and time to minimal
5
symptoms and few
therapeutic failures. The table below shows the results (primary and secondary
endpoints) of the two randomized controlled trials
:

The results of the open label studies were consistent with the above findings and support the repeated
use of Ruconest in the treatment of subsequent attacks of angioedema.
In the randomized controlled trials 39/41 (95%) of patients treated with Ruconest reached time to
beginning of relief within 4 hours. In an open label study 114/119 (95%) attacks treated with a single
dose of 50 U/kg reached time to beginning of relief within 4 hours. An additional dose of 50 U/kg was
administered for 13/133 (10%) attacks.
Paediatric population
Nine adolescent HAE patients (aged 13 to 17 years) were treated with 50 U/kg for 26 acute
angioedema attacks, and 7 (aged 16 to 17 years) with 2100 U for 24 acute angioedema attacks.
The European Medicines Agency has deferred the obligation to submit the results of studies with
Ruconest in one or more subsets of the paediatric population in treatment of acute angioedema attacks
(see section 4.2 for information on paediatric use).
5.2 Pharmacokinetic properties
Distribution
No formal distribution studies have been performed. The distribution volume of conestat alfa was
approximately 3 L, comparable to plasma volume.
Biotransformation and elimination
Based on animal data, conestat alfa is cleared from the circulation by the liver via receptor-mediated
endocytosis followed by complete hydrolysis/degradation.
After administration of Ruconest (50 U/kg) to asymptomatic HAE patients, a C
max
of 1.36 U/ml was
observed. The elimination half-life of conestat alfa was approximately 2 hours.
Excretion
There is no excretion, as conestat alfa is cleared from the circulation via receptor-mediated
endocytosis followed by complete hydrolysis/degradation in the liver.
6
5.3 Preclinical safety data
Preclinical data do not indicate any safety concern for the use of conestat alfa in humans based on
studies of safety pharmacology, single-dose toxicity, two-week sub-chronic toxicity
and local
tolerance
in various animal species including rats, dogs, rabbits and cynomolgus monkeys. Genotoxic
and carcinogenic potential is not expected.
Embryofetal studies in rat and rabbit; Daily single doses of vehicle or 625 U/kg/administration of
rhC1INH were administered intravenously to mated rats and rabbits. In the study in rats there were no
malformed fetuses in either the conestat alfa or the control group. In a rabbit embryotoxicity study an
increase in the incidence of fetal cardiac vessel defects (1.12% in the treatment group versus 0.03% in
historical controls) was observed for animals that were administered conestat alfa.

Further information
1.
WHAT RUCONEST IS AND WHAT IT IS USED FOR
Ruconest contains conestat alfa as the active substance. Conestat alfa is a
r
ecombinant form of
h
uman
C1
inh
ibitor (
rhC1INH
) and is produced using recombinant DNA technology from the milk of
rabbits.
Ruconest is to be used by adults with a rare inherited blood disorder, called Hereditary Angioedema
(HAE). These patients have a shortage of the C1 inhibitor protein in their blood. This can lead to
repeated attacks of swelling, pain in the abdomen, difficulty breathing and other symptoms.
The administration of conestat alfa (Ruconest) is to resolve the shortage of C1 inhibitor and will lead
to reduction of symptoms of an acute attack of HAE.
2.
BEFORE YOU USE RUCONEST
Do not use Ruconest
If you are or think you are allergic (hypersensitive) to rabbits
If you are allergic (hypersensitive) to conestat alfa or any of the other ingredients of the
medicinal product (see section 6).
Only use Ruconest if you have a negative test for rabbit allergy (IgE). Repeat this test every year or
after every 10 treatments with Ruconest, whichever occurs first.
Take special care with Ruconest
If you experience allergic reactions e.g. hives, rash, itching, dizziness, wheezing, difficulty breathing
or your tongue swells up following the administration of Ruconest, you should seek emergency
medical assistance
so that symptoms of your allergic reaction can be treated urgently.
Children and adolescents
Ruconest is not indicated for use in children and adolescents under 18 years old.
20
-
Keep this leaflet. You may need to read it again.
Using other medicines
Please inform your doctor if you are taking or have recently taken any other medicines, including
medicines obtained without a prescription.
If you are receiving acute treatment for blood clots, you should not be treated with Ruconest at the
same time.
Pregnancy and breast-feeding
It is not recommended to use Ruconest during pregnancy or breast-feeding.
If you plan becoming pregnant, discuss with your doctor before starting to use Ruconest.
Driving and using machines
Do not drive or use machinery if you feel dizzy or suffer from headache after using Ruconest.
3.
HOW TO USE RUCONEST
Ruconest will be given to you directly into a vein over a period of approximately 5 minutes by your
doctor or by a nurse. Your dose will be worked out based on your weight.
Most of the time a single dose is sufficient, but a second dose may be needed. No more than 2 doses
should be given within 24 hours.
The instructions for use are clearly described in the doctor’s information leaflet and are attached.
4.
POSSIBLE SIDE EFFECTS
Like all medicines, Ruconest can cause side effects, although not everybody gets them.
If your symptoms get worse and/or you develop a rash, tingling, difficulty breathing or your face or
tongue swells up, get medical attention
immediately.
This may indicate that you have developed an allergy to Ruconest.
Some side effects may occur during treatment with Ruconest:
Common (affect 1 to 10 users in 100):
headache
Uncommon (affect 1 to 10 users in 1,000):
sensation of tingling, prickling or numbness in the skin or limb (paraesthesia), dizziness, throat
irritation, abdominal pain, diarrhoea, nausea, hives and swelling of the skin.

The following information is intended for medical or healthcare professionals only:
POSOLOGY AND METHOD OF ADMINISTRATION
- Adults up to 84 kg body weight
One intravenous injection of 50 U/kg body weight.
- Adults of 84 kg body weight or greater
One intravenous injection of 4200 U (two vials).
In the majority of cases a single dose of Ruconest is sufficient to treat an acute angioedema attack.
In case of an insufficient clinical response, an additional dose (50 U/kg body weight up to 4200 U) can
be administered (see section 5.1).
Not more than two doses should be administered within 24 hours.
22
Dose calculation
Determine the patient’s body weight.
- Adults up to 84 kg body weight
For patients up to 84 kg calculate the volume required to be administered according to the formula
below:
Volume to be
administered (ml)
=
body weight (kg) times 50 (U/kg)
150 (U/ml)
=
body weight (kg)
3
- Adults of 84 kg body weight or greater
For patients of 84 kg or above the volume required to be administered is 28 ml corresponding to
4200 U (2 vials).
Reconstitute
each vial
with 14 ml water for injections (see section on Reconstitution below).

injections should be added slowly to avoid forceful impact on the powder and mixed gently to avoid
foaming of the solution. The reconstituted solution in each vial contains 2100 U conestat alfa at
150 U/ml and appears as a clear colourless solution.
The reconstituted solution in each vial should be inspected for particulate matter and discoloration. A
solution exhibiting particulates or discoloration should not be used. The medicinal product should be
used immediately.
No special requirements for disposal.
