Summary for the public


What is Suprelorin?

Suprelorin is an implant containing the active substance deslorelin. It is presented in a pre-loaded applicator.


What is Suprelorin used for?

Suprelorin is used for male dogs to make them temporarily infertile. It is used in healthy, sexuallymature dogs that have not been neutered. The implant is inserted subcutaneously, under the loose skin on the back between the lower neck and the lumbar area. Suprelorin starts being effective after about six weeks, and the effect continues for six months in the case of the 4.7 mg implant and 12 months in the case of the 9.4 mg implant, after which the dog can be re-implanted if necessary


How does Suprelorin work?

The active substance in Suprelorin, deslorelin, acts like the natural hormone gonadotropin-releasing hormone (GnRH) which controls the secretion of other hormones involved in fertility. Suprelorin is given as an implant that slowly releases a continuous low dose of deslorelin. This suppresses (blocks) the production of follicle stimulating hormone (FSH) and luteinising hormone (LH). As a result in male dogs, less testosterone circulates in the blood, the dog stops producing sperm and its libido is reduced. If a dog under treatment with Suprelorin were to mate with a bitch on heat, the chance of the bitch becoming pregnant would be extremely low.


How has Suprelorin been studied?

Suprelorin has been studied under field conditions in dogs weighing between 10 and 25 kg which were implanted before being followed up for up to a year. The studies looked at the effect of Suprelorin on blood testosterone levels, the size of the testicles and the ability of the dogs to produce semen for collection. In some of these studies, the dogs received Suprelorin more than once and were observed for up to a year after receiving the final implant. The safety of Suprelorin was studied after giving dogs more than 10 times the recommended dose rate.


What benefit has Suprelorin shown during the studies?

All studies showed a reduction of testosterone levels in the blood, a reduction in the size of the testicles, decreased libido and decreased spermatogenesis (when fewer sperm are produced by the testicles). In more than 95% of dogs, these effects started at six weeks after implantation. The majority of dogs regained normal semen characteristics approximately one year after the last treatment and dogs have been able to successfully mate with bitches, after treatment with Suprelorin was stopped.


What is the risk associated with Suprelorin?

Dogs can have some moderate swelling at the implant site in the two weeks after implantation. There can also some be some local reaction (e.g. inflammation, hardening) for up to three months after implantation. Any swelling or local reaction resolves naturally. The size of the testicles will decrease during treatment. Suprelorin is not recommended for use in dogs that have not yet reached puberty, as it has not been investigated in these animals.

For a full list of all side effects reported with Suprelorin, see the Package Leaflet.


What are the precautions for the person who gives the medicine or comes into contact with the animal?

This veterinary medicine has been developed especially for dogs and is not for use in humans. Although skin contact with the product is unlikely, if this occurs the exposed area should be washed immediately, as these types of substances may be absorbed through the skin. Pregnant women should not administer the product.

When administering the product, care should be taken to avoid accidental self-injection by ensuring that animals are suitably restrained and that the application needle is shielded until the moment of implantation. In case of accidental self-injection, medical advice should be sought immediately and the Package Leaflet or the label shown to the doctor.


Why has Suprelorin been approved?

The Committee for Medicinal Products for Veterinary Use (CVMP) concluded that the benefits of Suprelorin outweigh its risks for the induction of temporary infertility in healthy, entire, sexually mature male dogs and recommended that Suprelorin be given a marketing authorisation. The benefitrisk balance may be found in module 6 of this EPAR.

Product Characteristics

ANNEX I

SUMMARY OF PRODUCT CHARACTERISTICS


1.
NAME OF THE VETERINARY MEDICINAL PRODUCT
Suprelorin 4.7 mg implant for dogs
2.
QUALITATIVE AND QUANTITATIVE COMPOSITION
Active substance:
4.7 mg deslorelin (as deslorelin acetate)
Excipient(s):
For a full list of excipients, see section 6.1.
3.
PHARMACEUTICAL FORM
Implant
White to pale yellow cylindrical implant.
4.
CLINICAL PARTICULARS
4.1 Target species
Dogs (Male).
4.2 Indications for use, specifying the target species
For the induction of temporary infertility in healthy, entire, sexually mature male dogs.
4.3 Contraindications
None.
4.4 Special warnings
Infertility is achieved from 6 weeks up to at least 6 months after initial treatment. Treated dogs should
therefore still be kept away from bitches on heat within the first six weeks after initial treatment.
One out of 75 dogs treated with the product during clinical trials mated and tied with a bitch on heat
within six months of implantation, but this did not result in pregnancy. Should a treated dog mate with
a bitch between six weeks and six months after treatment, appropriate measures should be taken to
rule out the risk of pregnancy.
Any mating that occurs more than six months after the administration of the product may result in
pregnancy. However, it is not necessary to keep bitches away from treated dogs following subsequent
implantations, provided that the product is administered every six months.
The ability of dogs to sire offspring following their return to normal plasma testosterone levels, after
the administration of the product, has not been investigated.
With respect to testosterone levels (an established surrogate marker of fertility), during clinical trials
more than 80 % of dogs administered one or more implants, returned to normal plasma testosterone
levels (≥0.4 ng/ml) within 12 months of implantation. Ninety-eight percent of dogs returned to normal
plasma testosterone levels within 18 months of implantation. However, data demonstrating the
2
complete reversibility of clinical effects (reduced testicular size, reduced ejaculation volume, reduced
sperm count and reduced libido) including fertility after six months, or repeated implantation, are
limited.
During clinical trials, most of the smaller size dogs (<10 kg) maintained suppressed levels of
testosterone for more than 12 months following implantation. For very large dogs (>40 kg), data are
limited but duration of testosterone suppression was comparable to that seen in medium and large
dogs. The use of the product in dogs of less than 10 kg or more than 40 kg bodyweight, therefore,
should be subject to a risk/benefit assessment performed by the veterinarian.
4.5 Special precautions for use
Special precautions for use in animals
The use of the product in pre-pubertal dogs has not been investigated. It is therefore recommended that
dogs should be allowed to reach puberty before treatment with the product is initiated.
Data demonstrate that treatment with the product will reduce the libido of the dog, but other
behavioural changes (e.g. male-associated aggression) have not been investigated.
Special precautions to be taken by the person administering the veterinary medicinal product to
animals
Pregnant women should not administer the product. Another GnRH analogue has been shown to be
foetotoxic in laboratory animals. Specific studies to evaluate the effect of deslorelin when
administered during pregnancy have not been conducted.
Although skin contact with the product is unlikely, should this occur, wash the exposed area
immediately, as GnRH analogues may be absorbed through the skin.
When administering the product, take care to avoid accidental self-injection by ensuring that animals
are suitably restrained and the application needle is shielded until the moment of implantation.
In case of accidental self-injection, seek medical advice immediately, with a view to having the
implant removed. Show the package leaflet or the label to the physician.
4.6 Adverse reactions (frequency and seriousness)
Moderate swelling at the implant site may be observed for 14 days. Histologically, mild local reactions
with chronic inflammation of the connective tissue and some capsule formation and collagen
deposition have been seen at 3 months after administration.
A significant decrease in testicle size will be seen during the treatment period. In very rare cases, a
testicle may be able to ascend the inguinal ring.
4.7 Use during pregnancy, lactation or lay
Not applicable.
4.8 Interaction with other medicinal products and other forms of interaction
None known.
4.9 Amounts to be administered and administration route
Subcutaneous use.
3
The recommended dose is one implant per dog, irrespective of the size of the dog.
Disinfection of the implantation site should be undertaken prior to implantation to avoid introduction
of infection. If the hair is long, a small area should be clipped, if required.
Remove Luer Lock cap from the implanter. Attach the actuator to the implanter using the Luer Lock
connection.
The product should be implanted subcutaneously in the loose skin on the back between the lower neck
and the lumbar area. Avoid injection of the implant into fat, as release of the active substance might be
impaired in areas of low vascularisation. Lift the loose skin between the shoulder blades. Insert the
entire length of the needle subcutaneously. Fully depress the actuator plunger and, at the same time,
slowly withdraw the needle. Press the skin at the insertion site as the needle is withdrawn, and
maintain pressure for 30 seconds. Examine the syringe and needle to ascertain that the implant has not
remained within the syringe or needle, and that the spacer is visible. It may be possible to palpate the
implant in situ .
Repeat administration every six months to maintain efficacy.
Do not use the product if the foil pouch is broken.
The biocompatible implant does not require removal. However, should it be necessary to end
treatment, implants may be surgically removed by a veterinarian. Implants may be located using
ultrasound.
4.10 Overdose (symptoms, emergency procedures, antidotes), if necessary
No adverse reactions have been observed following simultaneous subcutaneous administration of up to
10 implants.
4.11 Withdrawalperiod(s)
Not applicable.
5.
PHARMACOLOGICAL PROPERTIES
Pharmacotherapeutic group: Gonadotrophin-releasing hormones (GnRH), ATCvet code: QH01CA93.
5.1 Pharmacodynamic properties
The GnRH agonist, deslorelin, acts by suppressing the function of the pituitary-gonadal axis when
applied in a low, continuous dose. This suppression results in the failure of treated animals to
synthesise and/or release follicle stimulating hormone (FSH) and luteinising hormone (LH), the
hormones responsible for the maintenance of fertility.
The continuous low dose of deslorelin will reduce the functionality of the male reproductive organs,
libido and spermatogenesis and lower the plasma testosterone levels, from 4-6 weeks after
implantation. A short transient increase in plasma testosterone may be seen immediately after
implantation. Measurement of plasma concentrations of testosterone has demonstrated the persistent
pharmacological effect of the continuing presence of deslorelin in the circulation for at least
six months following administration of the product.
4
5.2 Pharmacokinetic particulars
It has been shown that plasma deslorelin levels peak 7 to 35 days following administration of an
implant containing 5 mg radiolabelled deslorelin. The substance can be directly measured in the
plasma up to approximately 2.5 months post implantation. The metabolism of deslorelin is rapid.

4.
CLINICAL PARTICULARS
4.1 Target species
Dogs (male).
4.2 Indications for use, specifying the target species
For the induction of temporary infertility in healthy, entire, sexually mature male dogs.
4.3 Contraindications
None.
4.4 Special warnings
Infertility is achieved from 8 weeks up to at least 12 months after initial treatment. Treated dogs
should therefore still be kept away from bitches on heat within the first 8 weeks after initial treatment.
In 2 out of 30 dogs in the clinical trial infertility was not achieved until approximately 12 weeks after
initial treatment, but in most cases these animals are not capable of successfully siring offspring.
Should a treated dog mate with a bitch between 8 and 12 weeks after treatment, appropriate measures
should be taken to rule out the risk of pregnancy.
Any mating that occurs more than 12 months after the administration of Suprelorin may result in
pregnancy. However, it is not necessary to keep bitches away from treated dogs following subsequent
implantations for the initial 8 week period, provided that the veterinary medicinal product is
administered every 12 months.
In certain cases, the implant may be lost from a treated dog. If loss of the implant is suspected in
connection with the first implantation, this can be confirmed by observing no reduction in scrotal
circumference or plasma testosterone levels after 8 weeks from the suspected date of loss, as both
should reduce under correct implantation. If loss of the implant is suspected following re-implantation
after 12 months, a progressive increase will be seen in scrotal circumference and/or plasma
testosterone levels. In both of these circumstances a replacement implant should be administered.
7
The ability of dogs to sire offspring following their return to normal plasma testosterone levels, after
the administration of the veterinary medicinal product, has not been investigated.
With respect to testosterone levels (an established surrogate marker of fertility), during clinical trials
68 % of dogs administered one implant, returned to fertility within 2 years of implantation. 95% of
dogs had returned to normal plasma testosterone levels within 2.5 years of implantation. However,
data demonstrating the complete reversibility of clinical effects (reduced testicular size, reduced
ejaculation volume, reduced sperm count and reduced libido) including fertility after 12 months, or
repeated implantation, are limited.
Due to limited data, the use of Suprelorin in dogs of less than 10 kg or more than 40 kg bodyweight
should be subject to a risk/benefit assessment performed by the veterinarian. During clinical trials with
Suprelorin 4.7 mg, the mean duration of testosterone suppression was 1.5 times longer among smaller
size dogs (<10 kg) compared with all larger dogs.
4.5 Special precautions for use
Special precautions for use in animals
The use of Suprelorin in pre-pubertal dogs has not been investigated. It is therefore recommended that
dogs should be allowed to reach puberty before treatment with the veterinary medicinal product is
initiated.
Data demonstrate that treatment with Suprelorin will reduce the libido of the dog, but other
behavioural changes (e.g. male-associated aggression) have not been investigated.
Special precautions to be taken by the person administering the veterinary medicinal product to
animals
Pregnant women should not administer Suprelorin. Another GnRH analogue has been shown to be
foetotoxic in laboratory animals. Specific studies to evaluate the effect of deslorelin when
administered during pregnancy have not been conducted.
Although skin contact with the veterinary medicinal product is unlikely, should this occur, wash the
exposed area immediately, as GnRH analogues may be absorbed through the skin.
When administering the veterinary medicinal product, take care to avoid accidental self-injection by
ensuring that animals are suitably restrained and the application needle is shielded until the moment of
implantation.
In case of accidental self-injection, seek medical advice immediately and show the package leaflet or
the label to the physician, with a view to having the implant removed.
4.6 Adverse reactions (frequency and seriousness)
Moderate swelling at the implant site may be observed for 14 days. Histologically, mild local reactions
with chronic inflammation of the connective tissue and some capsule formation and collagen

Do not use the product if the foil pouch is broken.
One implant should be administered subcutaneously between the shoulder blades of the dog.
9.
ADVICE ON CORRECT ADMINISTRATION
Remove Luer Lock cap from the implanter. Attach the actuator to the implanter using the Luer Lock
connection.
Disinfection of the implantation site should be undertaken prior to implantation to avoid introduction
of infection.
Select the implant site by locating the area of the back midway between the shoulder blades. Avoid
injection of the implant into fat, as release of the active substance might be impaired in areas of low
vascularisation. If the hair is long, a small area may be clipped, if required. Lift the loose skin between
the shoulder blades. Insert the entire length of the needle subcutaneously. Fully depress the actuator
plunger and, at the same time, slowly withdraw the needle. Press the skin at the insertion site as the
needle is withdrawn, and maintain pressure for 30 seconds. Examine the syringe and needle to
ascertain that the implant has not remained within the syringe or needle, and that the spacer is visible.
It may be possible to palpate the implant in situ .
The biocompatible implant does not require removal. However, should it be necessary to end
treatment, implants may be surgically removed by a veterinarian. Implants may be located using
ultrasound.
The actuator can be re-used.
10. WITHDRAWAL PERIOD
Not applicable.
11. SPECIAL STORAGE PRECAUTIONS
Keep out of the reach and sight of children.
Store in a refrigerator (2
°
C – 8
°
C)
Do not freeze
Do not use after the expiry date which is stated on the carton.
12. SPECIAL WARNING(S)
Pregnant women should not administer the product. Another GnRH analogue has been shown to be
foetotoxic in laboratory animals. Specific studies to evaluate the effect of deslorelin when
administered during pregnancy have not been conducted.
24
Although skin contact with the product is unlikely, should this occur, wash the exposed area
immediately, as GnRH analogues may be absorbed through the skin.
When administering the product, take care to avoid accidental self-injection by ensuring that animals
are suitably restrained and the application needle is shielded until the moment of implantation.
In case of accidental self-injection, seek medical advice immediately, with a view to having the
implant removed. Show the package leaflet or the label to the physician.
Infertility is achieved from 6 weeks up to at least 6 months after initial treatment. Treated dogs should
therefore still be kept away from bitches on heat within the first six weeks after initial treatment.
One out of 75 dogs treated with the product during clinical trials mated and tied with a bitch on heat
within six months of implantation, but this did not result in pregnancy. Should a treated dog mate with
a bitch between six weeks and six months after treatment, appropriate measures should be taken to
rule out the risk of pregnancy.
Any mating that occurs more than six months after the administration of the product may result in
pregnancy. However, it is not necessary to keep bitches away from treated dogs following subsequent
implantations, provided that the product is administered every six months.
The ability of dogs to sire offspring following their return to normal plasma testosterone levels, after
the administration of the product, has not been investigated.
With respect to testosterone levels (an established surrogate marker of fertility), during clinical trials
more than 80 % of dogs administered one or more implants, returned to normal plasma testosterone
levels (≥0.4 ng/ml) within 12 months of implantation. Ninety-eight percent of dogs returned to normal
plasma testosterone levels within 18 months of implantation. However, data demonstrating the
complete reversibility of clinical effects (reduced testicular size, reduced ejaculation volume, reduced
sperm count and reduced libido) including fertility after six months, or repeated implantation, are
limited.
During clinical trials, most of the smaller size dogs (<10 kg) maintained suppressed levels of
testosterone for more than 12 months following implantation. For very large dogs (>40 kg), data are
limited but duration of testosterone suppression was comparable to that seen in medium and large
dogs. The use of the product in dogs of less than 10 kg or more than 40 kg bodyweight, therefore,
should be subject to a risk/benefit assessment performed by the veterinarian.
The use of the product in pre-pubertal dogs has not been investigated. It is therefore recommended that
dogs should be allowed to reach puberty before treatment with the product is initiated.
Data demonstrates that treatment with the product will reduce the libido of the dog, but other
behavioural changes (e.g. male-associated aggression) have not been investigated.
No adverse reactions have been observed following simultaneous subcutaneous administration of up to
10 implants.
13. SPECIAL PRECAUTIONS FOR THE DISPOSAL OF UNUSED PRODUCT OR WASTE
MATERIALS, IF ANY
Any unused veterinary medicinal product or waste materials derived from such veterinary medicinal
products should be disposed of in accordance with local requirements. The actuator can be re-used.

12. SPECIAL WARNING(S)
Pregnant women should not administer Suprelorin. Another GnRH analogue has been shown to be
foetotoxic in laboratory animals. Specific studies to evaluate the effect of deslorelin when
administered during pregnancy have not been conducted.
Although skin contact with the veterinary medicinal product is unlikely, should this occur, wash the
exposed area immediately, as GnRH analogues may be absorbed through the skin.

When administering the veterinary medicinal product, take care to avoid accidental self-injection by
ensuring that animals are suitably restrained and the application needle is shielded until the moment of
implantation.
In case of accidental self-injection, seek medical advice immediately and show the package leaflet or
the label to the physician, with a view to having the implant removed.
Infertility is achieved from 8 weeks up to at least 12 months after initial treatment. Treated dogs
should therefore still be kept away from bitches on heat within the first 8 weeks after initial treatment.
In 2 out of 30 dogs in the clinical trial infertility was not achieved until approximately 12 weeks after
initial treatment, but in most cases these animals are not capable of successfully siring offspring.
Should a treated dog mate with a bitch between 8 and 12 weeks after treatment, appropriate measures
should be taken to rule out the risk of pregnancy.
Any mating that occurs more than 12 months after the administration of the Suprelorin may result in
pregnancy. However, it is not necessary to keep bitches away from treated dogs following subsequent
implantations for the initial 8 week period, provided that the veterinary medicinal product is
administered every 12 months.
In certain cases, the implant may be lost from a treated dog. If loss of the implant is suspected in
connection with the first implantation, this can be confirmed by observing no reduction in scrotal
circumference or plasma testosterone levels after 8 weeks from the suspected date of loss, as both
should reduce under correct implantation. If loss of the implant is suspected following re-implantation
after 12 months, a progressive increase will be seen in scrotal circumference and/or plasma
testosterone levels. In both of these circumstances a replacement implant should be administered.
The ability of dogs to sire offspring following their return to normal plasma testosterone levels, after
the administration of Suprelorin, has not been investigated.
With respect to testosterone levels (an established surrogate marker of fertility), during clinical trials
68 % of dogs administered one implant, returned to fertility within 2 years of implantation. 95 % of
dogs had returned to normal plasma testosterone levels within 2.5 years of implantation. However,
data demonstrating the complete reversibility of clinical effects (reduced testicular size, reduced
ejaculation volume, reduced sperm count and reduced libido) including fertility after 12 months, or
repeated implantation, are limited.
Due to limited data, the use of Suprelorin in dogs of less than 10 kg or more than 40 kg bodyweight
should be subject to a risk/benefit assessment performed by the veterinarian. During clinical trials with
Suprelorin 4.7 mg, the mean duration of testosterone suppression was 1.5 times longer among smaller
size dogs (<10 kg) compared with all larger dogs.
The use of Suprelorin in pre-pubertal dogs has not been investigated. It is therefore recommended that
dogs should be allowed to reach puberty before treatment with the veterinary medicinal product is
initiated.
Data demonstrate that treatment with the veterinary medicinal product will reduce the libido of the
dog, but other behavioural changes (e.g. male-associated aggression) have not been investigated.
No adverse reactions have been observed following simultaneous subcutaneous administration of the
equivalent of six implants.
