Qdenga is indicated for the prevention of dengue disease in individuals from 4 years of age.
The use of Qdenga should be in accordance with official recommendations.
4.2 Posology and method of administration
PosologyIndividuals from 4 years of age
Qdenga should be administered as a 0.5 mL dose at a two-dose (0 and 3 months) schedule.
The need for a booster dose has not been established.
Other paediatric population (children <4 years of age)
The safety and efficacy of Qdenga in children aged less than 4 years has not yet been established.
Currently available data are described in section 4.8 but no recommendation on a posology can bemade.
ElderlyNo dose adjustment is required in elderly individuals ≥60 years of age. See section 4.4.
Method of administrationAfter complete reconstitution of the lyophilised vaccine with the solvent, Qdenga should beadministered by subcutaneous injection preferably in the upper arm in the region of deltoid.
Qdenga must not be injected intravascularly, intradermally or intramuscularly.
The vaccine should not be mixed in the same syringe with any other vaccines or other parenteralmedicinal products.
For instructions on reconstitution of Qdenga before administration, see section 6.6.
4.3 Contraindications
* Hypersensitivity to the active substances or to any of the excipients listed in section 6.1 orhypersensitivity to a previous dose of Qdenga.
* Individuals with congenital or acquired immune deficiency, including those receivingimmunosuppressive therapies such as high doses of systemic corticosteroids (e.g. 20 mg/dayor 2 mg/kg body weight/day of prednisone for 2 weeks or more) within 4 weeks prior tovaccination, or any other medicinal product with known immunosuppressive propertiesincluding chemotherapy. The time to avoid vaccination after immunosuppressive treatmentshould be considered on an individual basis.
* Individuals with symptomatic HIV infection or with asymptomatic HIV infection whenaccompanied by evidence of impaired immune function.
* Pregnant women (see section 4.6).
* Breast-feeding women (see section 4.6).
4.4 Special warnings and precautions for use
TraceabilityIn order to improve the traceability of biological medicinal products, the name and the batch numberof the administered product should be clearly recorded.
General recommendationsAnaphylaxis
Anaphylaxis has been reported in individuals who have received Qdenga. As with all injectablevaccines, appropriate medical treatment and supervision must always be readily available in the eventof a rare anaphylactic reaction following administration of the vaccine.
Review of medical history
Vaccination should be preceded by a review of the individual’s medical history (especially with regardto previous vaccination and possible hypersensitivity reactions which occurred after vaccination).
Concurrent illnessVaccination with Qdenga should be postponed in subjects suffering from an acute severe febrileillness. The presence of a minor infection, such as a cold, should not result in a deferral of vaccination.
Limitations of vaccine effectivenessA protective immune response with Qdenga may not be elicited in all vaccinees against all serotypesof dengue virus and may decline over time (see section 5.1). It is currently unknown whether a lack ofprotection could result in an increased severity of dengue. It is recommended to continue personalprotection measures against mosquito bites after vaccination. Individuals should seek medical care ifthey develop dengue symptoms or dengue warning signs.
There are no data on the use of Qdenga in subjects above 60 years of age and limited data in patientswith chronic medical conditions.
Anxiety-related reactionsAnxiety-related reactions, including vasovagal reactions (syncope), hyperventilation or stress‐relatedreactions may occur in association with vaccination as a psychogenic response to the needle injection.
It is important that precautions are in place to avoid injury from fainting.
Women of childbearing potentialAs with other live attenuated vaccines, women of childbearing potential should avoid pregnancy for atleast one month following vaccination (see sections 4.6 and 4.3).
OtherQdenga must not be administered by intravascular, intradermal or intramuscular injection.
ExcipientsQdenga contains less than 1 mmol sodium (23 mg) per dose, that is to say essentially ‘sodium-free’.
Qdenga contains less than 1 mmol potassium (39 mg) per dose, that is to say essentially ‘potassium-free’.
4.5 Interaction with other medicinal products and other forms of interaction
For patients receiving treatment with immunoglobulins or blood products containingimmunoglobulins, such as blood or plasma, it is recommended to wait for at least 6 weeks, andpreferably for 3 months, following the end of treatment before administering Qdenga, in order to avoidneutralisation of the attenuated viruses contained in the vaccine.
Qdenga should not be administered to subjects receiving immunosuppressive therapies such as highdoses of systemic corticosteroids within 4 weeks prior to vaccination, or any other medicinal productwith known immunosuppressive properties including chemotherapy (see section 4.3). The time toavoid vaccination after immunosuppressive treatment should be considered on an individual basis.
Use with other vaccinesIf Qdenga is to be given at the same time as another injectable vaccine, the vaccines should always beadministered at different injection sites.
Qdenga may be administered concomitantly with a hepatitis A vaccine. Coadministration has beenstudied in adults.
Qdenga may be administered concomitantly with a yellow fever vaccine. In a clinical study involvingapproximately 300 adult subjects who received Qdenga concomitantly with yellow fever 17D vaccine,there was no effect on yellow fever seroprotection rate. Dengue antibody responses were decreasedfollowing concomitant administration of Qdenga and yellow fever 17D vaccine. The clinicalsignificance of this finding is unknown.
Qdenga may be administered concomitantly with a human papillomavirus (HPV) vaccine (see section5.1).
4.6 Fertility, pregnancy and lactation
Women of childbearing potentialWomen of childbearing potential should avoid pregnancy for at least one month followingvaccination. Women who intend to become pregnant should be advised to delay vaccination (seesections 4.4 and 4.3).
PregnancyAnimal studies are insufficient with respect to reproductive toxicity (see section 5.3).
There is limited amount of data from the use of Qdenga in pregnant women. These data are notsufficient to conclude on the absence of potential effects of Qdenga on pregnancy, embryo-foetaldevelopment, parturition and post-natal development.
Qdenga is a live attenuated vaccine, therefore Qdenga is contraindicated during pregnancy (see section4.3).
Breast-feedingIt is unknown whether Qdenga is excreted in human milk. A risk to the newborns/infants cannot beexcluded.
Qdenga is contraindicated during breast-feeding (see section 4.3).
FertilityAnimal studies are insufficient with respect to reproductive toxicity (see section 5.3).
No specific studies have been performed on fertility in humans.
4.7 Effects on ability to drive and use machines
Qdenga has minor influence on the ability to drive and use machines.
4.8 Undesirable effects
Summary of the safety profileIn clinical studies, the most frequently reported reactions in subjects 4 to 60 years of age wereinjection site pain (50%), headache (35%), myalgia (31%), injection site erythema (27%), malaise(24%), asthenia (20%) and fever (11%).
These adverse reactions usually occurred within 2 days after the injection, were mild to moderate inseverity, had a short duration (1 to 3 days) and were less frequent after the second injection of Qdengathan after the first injection.
Vaccine viraemia
In clinical study DEN-205, transient vaccine viraemia was observed after vaccination with Qdenga in49% of study participants who had not been infected with dengue before and in 16% of studyparticipants who had been infected with dengue before. Vaccine viraemia usually started in the secondweek after the first injection and had a mean duration of 4 days. Vaccine viraemia was associated withtransient, mild to moderate symptoms, such as headache, arthralgia, myalgia and rash in some subjectsthat may also occur with dengue. Vaccine viraemia was rarely detected after the second dose.
Dengue diagnostic tests may be positive during vaccine viraemia and cannot be used to distinguishvaccine viraemia from wild type dengue infection.
Tabulated list of adverse reactionsAdverse reactions associated with Qdenga obtained from clinical studies and post-authorisationexperience are tabulated below (Table 1).
The safety profile presented below is based on data generated in placebo-controlled clinical studiesand post-authorisation experience. Pooled analysis of clinical studies included data from 14,627 studyparticipants aged 4 to 60 years (13,839 children and 788 adults) who have been vaccinated with
Qdenga. This included a reactogenicity subset of 3,830 participants (3,042 children and 788 adults).
Adverse reactions are listed according to the following frequency categories:
Very common: 1/10
Common: 1/100 to <1/10

Adverse reactions reported more commonly in children than in adults were fever (11% versus3%), upper respiratory tract infection (11% versus 3%), nasopharyngitis (6% versus 0.6%),pharyngotonsillitis (2% versus 0.3%), and influenza like illness (1% versus 0.1%). Adverse reactionsreported less commonly in children than adults were injection site erythema (2% versus 27%), nausea(0.03% versus 0.8%) and arthralgia (0.03% versus 1%).
The following reactions were collected in 357 children below 6 years of age vaccinated with Qdenga:
decreased appetite (17%), somnolence (13%) and irritability (12%).
Paediatric data in subjects below 4 years of age, i.e. outside the age indication
Reactogenicity in subjects below 4 years of age was assessed in 78 subjects who received at least onedose of Qdenga of which 13 subjects received the indicated 2-dose regimen. Reactions reported withvery common frequency were irritability (25%), fever (17%), injection site pain (17%) and loss ofappetite (15%). Somnolence (8%) and injection site erythema (3%) were reported with commonfrequency. Injection site swelling was not observed in subjects below 4 years of age.
Reporting of suspected adverse reactionsReporting suspected adverse reactions after authorisation of the medicinal product is important. Itallows continued monitoring of the benefit/risk balance of the medicinal product. Healthcareprofessionals are asked to report any suspected adverse reactions via the national reporting systemlisted in Appendix V.
4.9 Overdose
No cases of overdose have been reported.
5. PHARMACOLOGICAL PROPERTIES
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: Vaccines, Viral vaccines, ATC code: J07BX04
Mechanism of actionQdenga contains live attenuated dengue viruses. The primary mechanism of action of Qdenga is toreplicate locally and elicit humoral and cellular immune responses against the four dengue virusserotypes.
Clinical efficacyThe clinical efficacy of Qdenga was assessed in study DEN-301, a pivotal Phase 3, double-blind,randomised, placebo-controlled study conducted across 5 countries in Latin America (Brazil,
Colombia, Dominican Republic, Nicaragua, Panama) and 3 countries in Asia (Sri Lanka, Thailand, the
Philippines). A total of 20,099 children aged between 4 and 16 years were randomised (2:1 ratio) toreceive Qdenga or placebo, regardless of previous dengue infection.
Efficacy was assessed using active surveillance across the entire study duration. Any subject withfebrile illness (defined as fever ≥38°C on any 2 of 3 consecutive days) was required to visit the studysite for dengue fever evaluation by the investigator. Subjects/guardians were reminded of thisrequirement at least weekly to maximise the detection of all symptomatic virologically confirmeddengue (VCD) cases. Febrile episodes were confirmed by a validated, quantitative dengue RT-PCR todetect specific dengue serotypes.
Clinical efficacy data for subjects 4 to 16 years of age
The Vaccine Efficacy (VE) results, according to the primary endpoint (VCD fever occurring from 30days to 12 months after the second vaccination) are shown in Table 2. The mean age of the perprotocol trial population was 9.6 years (standard deviation of 3.5 years) with 12.7% subjects in the 4-5years, 55.2% in the 6-11 years and 32.1% in the 12-16 years age-groups. Of these, 46.5% were in Asiaand 53.5% were in Latin America, 49.5% were females and 50.5% were males. The dengue serostatusat baseline (before the first injection) was assessed in all subjects by microneutralisation test (MNT50)to allow Vaccine Efficacy (VE) assessment by baseline serostatus. The baseline dengue seronegativityrate for the overall per protocol population was 27.7%.

VE results according to the secondary endpoints, preventing hospitalisation due to VCD fever,preventing VCD fever by serostatus, by serotype and preventing severe VCD fever are shown in
Table 3. For severe VCD fever, two types of endpoints were considered: clinically severe VCD casesand VCD cases that met the 1997 WHO criteria for Dengue Haemorrhagic Fever (DHF). The criteriaused in Trial DEN-301 for the assessment of VCD severity by an independent “Dengue Case severity
Adjudication Committee” (DCAC) were based on the WHO 2009 guidelines. The DCAC assessed allcases of hospitalisation due to VCD utilizing predefined criteria which included an assessment ofbleeding abnormality, plasma leakage, liver function, renal function, cardiac function, the centralnervous system, and shock. In Trial DEN-301 VCD cases meeting the WHO 1997 criteria for DHFwere identified using a programmed algorithm, i.e., without applying medical judgment. Broadly, thecriteria included presence of fever lasting 2 to 7 days, haemorrhagic tendencies, thrombocytopenia,and evidence of plasma leakage.

Clinical efficacy for subjects from 17 years of age
No clinical efficacy study has been conducted in subjects from 17 years of age. The efficacy of
Qdenga in subjects from 17 years of age is inferred from the clinical efficacy in 4 to 16 years of age bybridging of immunogenicity data (see below).
ImmunogenicityIn the absence of correlates of protection for Dengue, the clinical relevance of immunogenicity dataremains to be fully understood.
Immunogenicity data for subjects 4 to 16 years of age in endemic areas
The Geometric Mean Titres (GMTs) by baseline dengue serostatus in subjects 4 to 16 years of age instudy DEN-301 are shown in Table 6.

The bridging of efficacy is based on immunogenicity data and results from a non-inferiority analysis,comparing post-vaccination GMTs in the baseline dengue seronegative populations of DEN-301 and
DEN-304 (Table 8). Protection against dengue disease is expected in adults although the actualmagnitude of efficacy relative to that observed in children and adolescents is unknown.

Long-term persistence of antibodies
The long-term persistence of neutralising antibodies was shown in study DEN-301, with titresremaining well above the pre-vaccination levels for all four serotypes, up to 51 months after the firstdose.
Co-administration with HPV vaccine
In study DEN-308 involving approximately 300 subjects aged 9 to 14 years who received Qdengaconcomitantly with a 9-valent HPV vaccine, there was no effect on the immune response to the HPVvaccine. The study only tested co-administration of the first doses of Qdenga and the 9-valent HPVvaccine. Non-inferiority of the Qdenga immune response, when Qdenga and the 9-valent HPV vaccinewere co-administered, has not been directly assessed in the study. In the dengue seronegative studypopulation, dengue antibody responses after co-administration were in the same range as thoseobserved in the Phase 3 study (DEN-301) where efficacy against VCD and hospitalised VCD wasshown.
5.2 Pharmacokinetic properties
No pharmacokinetic studies have been performed with Qdenga.
5.3 Preclinical safety data
Non-clinical safety data revealed no special hazard for humans based on conventional studies of singledose, local tolerance, repeated dose toxicity, and toxicity to reproduction and development. In adistribution and shedding study, there was no shedding of Qdenga RNA in faeces and urine,confirming a low risk for vaccine shedding to the environment or transmission from vaccinees. Aneurovirulence study shows that Qdenga is not neurotoxic.
Although no relevant hazard was identified, the relevance of the reproductive toxicity studies islimited, since rabbits are not permissive for dengue virus infection.

6.6 Special precautions for disposal and other handling
Instructions for reconstitution of the vaccine with the solvent presented in vial
Qdenga is a 2-component vaccine that consists of a vial containing lyophilised vaccine and a vialcontaining solvent. The lyophilised vaccine must be reconstituted with solvent prior to administration.
Use only sterile syringes for reconstitution and injection of Qdenga. Qdenga should not be mixed withother vaccines in the same syringe.
To reconstitute Qdenga, use only the solvent (0.22% sodium chloride solution) supplied with thevaccine since it is free of preservatives or other anti-viral substances. Contact with preservatives,antiseptics, detergents, and other anti-viral substances is to be avoided since they may inactivate thevaccine.
Remove the vaccine and solvent vials from the refrigerator.
* Remove the caps from both vials and clean the surfaceof stoppers on top of the vials using an alcohol wipe.
* Attach a sterile needle to a sterile 1 mL syringe andinsert the needle into the solvent vial. The recommendedneedle is 23G.
* Slowly press the plunger completely down.
* Turn the vial upside down, withdraw the entire contentsof the vial and continue to pull plunger out to 0.75 mL.
Solvent vial A bubble should be seen inside of the syringe.
* Invert the syringe to bring the bubble back to theplunger.
* Insert the needle of the syringe assembly into thelyophilised vaccine vial.
* Direct the flow of the solvent toward the side of the vialwhile slowly depressing the plunger to reduce the chanceof forming bubbles.
Lyophilised vaccine vial
* Release your finger from the plunger and, holding theassembly on a flat surface, gently swirl the vial in bothdirections with the needle syringe assembly attached.
* DO NOT SHAKE. Foam and bubbles may form in thereconstituted product.
* Let the vial and syringe assembly sit for a while until thesolution becomes clear. This takes about 30-60 seconds.
Reconstituted vaccine
Following reconstitution, the resulting solution should be clear, colourless to pale yellow, andessentially free of foreign particulates. Discard the vaccine if particulates are present and/or if itappears discoloured.
* Withdraw the entire volume of the reconstituted Qdengasolution with the same syringe until an air bubbleappears in the syringe.
* Remove the needle syringe assembly from the vial.
* Hold the syringe with the needle pointing upwards, tapthe side of the syringe to bring the air bubble to the top,discard the attached needle and replace with a newsterile needle, expel the air bubble until a small drop of
Reconstituted vaccine the liquid forms at the top of the needle. Therecommended needle is 25G 16 mm.
* Qdenga is ready to be administered by subcutaneousinjection.
Qdenga should be administered immediately after reconstitution. Chemical and physical in-usestability have been demonstrated for 2 hours at room temperature (up to 32.5°C) from the time ofreconstitution of the vaccine vial. After this time period, the vaccine must be discarded. Do not returnit to the refrigerator. From a microbiological point of view Qdenga should be used immediately. If notused immediately, in-use storage times and conditions are the responsibility of the user.
