DENGVAXIA
(Dengue Tetravalent Vaccine, Live) Suspension for Subcutaneous Injection
DENGVAXIA (Dengue Tetravalent Vaccine, Live) is a sterile suspension for subcutaneous injection. DENGVAXIA is supplied as a vial of lyophilized vaccine antigen, which must be reconstituted at the time of use with 0.6 mL from the accompanying vial of diluent (0.4% sodium chloride). After reconstitution, DENGVAXIA is a clear, colorless suspension (trace amounts of white to translucent proteinaceous particles may be present). [See DOSAGE AND ADMINISTRATION]
After reconstitution, each 0.5 mL dose of DENGVAXIA contains 4.5 - 6.0 log10 CCID50 of each of the chimeric yellow fever dengue (CYD) virus serotypes 1, 2, 3, and 4. Each 0.5 mL dose is formulated to contain 2 mg sodium chloride and the following ingredients as stabilizers: 0.56 mg essential amino acids (including L-phenylalanine), 0.2 mg non-essential amino acids, 2.5 mg L-arginine hydrochloride, 18.75 mg sucrose, 13.75 mg D-trehalose dihydrate, 9.38 mg D-sorbitol, 0.18 mg trometamol, and 0.63 mg urea.
Each of the four CYD viruses (CYD-1, CYD-2, CYD-3, and CYD-4) in DENGVAXIA was constructed using recombinant DNA technology by replacing the sequences encoding the pre-membrane (prM) and envelope (E) proteins in the yellow fever (YF) 17D204 vaccine virus genome with those encoding for the homologous sequences of dengue virus serotypes 1, 2, 3, and 4, respectively. Each CYD virus is cultured separately in Vero cells (African Green Monkey kidney) under serum-free conditions, harvested from the supernatant of the Vero cells and purified by membrane chromatography and ultrafiltration. The purified and concentrated harvest of each CYD virus is then diluted in a stabilizer solution to produce the four monovalent drug substances. The final bulk product is a mixture of the four monovalent drug substances diluted in the stabilizer solution. The final bulk product is sterilized by filtration at 0.22 μm, filled into vials and freeze-dried.
DENGVAXIA does not contain preservative.
The vial stoppers for the Lyophilized Vaccine Antigen and Diluent vials of DENGVAXIA are not made with natural rubber latex.
DENGVAXIA® (Dengue Tetravalent Vaccine, Live) is a vaccine indicated for the prevention of dengue disease caused by dengue virus serotypes 1, 2, 3 and 4. DENGVAXIA is approved for use in individuals 9 through 16 years of age with laboratory-confirmed previous dengue infection and living in endemic areas.
For subcutaneous use only.
Three doses (0.5 mL each) 6 months apart (at month 0, 6, and 12).
The package contains a vial of lyophilized vaccine antigen and a vial of saline diluent (0.4% NaCl).
After removing the “flip-off” caps, cleanse the lyophilized vaccine antigen and diluent vial stoppers with a suitable germicide. Do not remove the vial stoppers or metal seals holding them in place.
To reconstitute DENGVAXIA, use a sterile needle and syringe to withdraw 0.6 mL from the diluent vial and inject it into the vial of the lyophilized vaccine antigen. Swirl the vial gently.
Changing needles between withdrawing the vaccine from the vial and injecting it into a recipient is not necessary unless the needle has been damaged or contaminated.

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a vaccine cannot be directly compared to rates in the clinical trials of another vaccine and may not reflect the rates observed in practice.
The safety of DENGVAXIA in subjects 9 through 16 years of age was evaluated in 9 randomized, placebo-controlled, multicenter clinical trials. In these studies, a total of 19,102 subjects 9 through 16 years of age received at least one dose of DENGVAXIA and 9,484 received placebo (0.9% sodium chloride). Overall, 50.9% of trial participants who received DENGVAXIA or placebo were female. Racial groups were reported as 18.9% Asian, 13% American Indian or Alaska native, 6.4% caucasian, 2.6% black, and 59.1% as other. In the largest study (Study 1, NCT01374516; N = 20,869) conducted in four Latin American countries and Puerto Rico, most subjects (99.9%) reported Hispanic ethnicity. All studies enrolled subjects irrespective of evidence of previous dengue infection.
In a multi-center, observer-blind, randomized (2:1), placebo-controlled trial conducted in four Latin American countries and Puerto Rico (Study 1, NCT01374516), 2,000 subjects (out of a total of 20,869 subjects) were recruited during the first 2 months of enrollment for inclusion in the reactogenicity subset. Solicited adverse reactions were recorded daily for 14 days following each vaccination.
Table 1 presents the frequency and severity of solicited injection site reactions reported within 7 days and systemic adverse reactions reported within 14 days following receipt of DENGVAXIA or placebo.

In Study 1, 1.2% of subjects in the DENGVAXIA group (16/1,333) and 0.8% of subjects in the placebo group (5/664) reported at least 1 unsolicited non-serious adverse reaction within 28 days following any dose.
In this study, 0.7% of the subjects in the DENGVAXIA group and 0.5% in the placebo group reported at least one unsolicited non-serious injection site adverse reaction. The unsolicited non-serious adverse reactions were injection site pain, hematoma, pruritus and anesthesia in the vaccine group and pain and induration in the control group.
In this study, 0.5% of the subjects in the DENGVAXIA group and 0.3% in the placebo group reported at least one unsolicited non-serious systemic adverse reaction. The unsolicited non-serious systemic adverse reactions were malaise, abdominal pain, vomiting, dyspnea, generalized erythema, vertigo, asthma crisis and urticaria in the vaccine group and pruritus and lymphadenitis in the control group.
Most unsolicited non-serious adverse reactions started within 3 days of any injection and resolved within 3 days or less.
A total of 2 subjects (one subject with asthma crisis and urticaria occurring the day of the first dose, and one subject with malaise occurring 20 days after the first dose) in the DENGVAXIA group (0.2%) and none in the placebo group reported unsolicited non-serious Grade 3 (significant; prevents daily activity) adverse reactions.
Subjects were monitored for severe dengue from Day 0 (day of first study vaccination) to Month 60-72 (after first study vaccination) in three multi-center, observer-blind, randomized (2:1), placebo-controlled trials conducted in Latin America and Puerto Rico (Study 1, NCT01374516) and the Asia-Pacific region (Study 2, NCT01373281; Study 3, NCT00842530). A subset of 3,203 subjects (80.1%) enrolled in Study 3 were reconsented to participate in an extension study to evaluate safety of DENGVAXIA for 72 months (Study 4, NCT01983553). A total of 18,265 children and adolescents 9 through 16 years of age enrolled in these trials received at least one dose of DENGVAXIA. Table 2 presents the incidences and hazard ratios of severe dengue from Month 13 to Month 60-72 post-vaccination with DENGVAXIA or placebo in children and adolescents 9 through 16 years of age, by dengue baseline serostatus. An increased rate of severe dengue was observed following vaccination with DENGVAXIA and subsequent infection with any dengue virus serotype in persons not previously infected by dengue virus.

In the 9 studies conducted among subjects 9 through 16 years of age (NCT 01374516, NCT01373281, NCT00842530, NCT00993447, NCT00875524, NCT00788151, NCT00880893, NCT01187433, NCT01254422), subjects were monitored for serious adverse events (SAEs) for at least 6 months after the last dose of DENGVAXIA.
The proportions of subjects who reported at least 1 non-fatal SAE within 28 days following any dose were 0.6% (123/19,102) in the DENGVAXIA group and 0.8% (73/9,484) in the placebo group. The following events were considered related to DENGVAXIA: asthma attack (day of Dose 1), urticaria (day of Dose 2) and convulsion (day of Dose 1).
The proportions of subjects who reported at least 1 non-fatal SAE after 28 days and up to 6 months after any dose were similar in the 2 groups: 2.8% in the DENGVAXIA group (534/19,102) and 3.2% in the placebo group (307/9,484). None of these SAEs were considered related to the vaccination.
From the first administered dose up to Month 72, 51 deaths (0.3%) for subjects who received DENGVAXIA and 26 deaths (0.3 %) for subjects who received placebo were reported in the 9 studies conducted among subjects 9 though 16 years of age. None of the deaths were considered related to vaccination. Causes of death among subjects were consistent with those generally reported in children and adolescent populations.
In addition to events reported in clinical trials for DENGVAXIA, the following adverse events have been spontaneously reported during post-approval use. Because these events are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to the vaccine.
The following adverse events were included based on one or more of the following factors: severity, frequency of reporting, or strength of evidence for a causal relationship to DENGVAXIA.
Allergic including anaphylactic reactions.
Severe dengue infection, including hospitalization and death, in individuals for whom dengue infection status prior to vaccination was unknown and who were subsequently infected with dengue following vaccination.
Data are not available to establish the safety and immunogenicity of concomitant administration of DENGVAXIA with recommended adolescent vaccines.
Immunosuppressive therapies, including irradiation, antimetabolites, alkylating agents, cytotoxic drugs and corticosteroids (used in greater than physiologic doses), may reduce the immune response to DENGVAXIA.
DENGVAXIA may cause temporary depression of tuberculin purified protein derivative (PPD) test sensitivity, leading to false negative results. Tuberculin testing should be performed before DENGVAXIA is administered or at least 1 month following vaccination with DENGVAXIA.
Included as part of the "PRECAUTIONS" Section
In unvaccinated individuals, first dengue infections rarely cause severe dengue, while second dengue infections with a different serotype are associated with an increased risk of severe dengue. DENGVAXIA administration to individuals not previously infected by dengue virus is associated with an increased risk of severe dengue disease when the vaccinated individual is subsequently infected with any dengue virus serotype. Therefore, healthcare professionals must evaluate individuals for prior dengue infection to avoid vaccinating individuals who have not been previously infected by dengue virus.
Previous infection by dengue virus can be evaluated through a medical record of previous laboratory-confirmed dengue infection or through serotesting prior to vaccination.
There is no FDA cleared test available to determine a previous dengue infection. Available non-FDA cleared tests may yield false positive results (e.g., due to cross-reactivity with other flaviviruses).
DENGVAXIA may cause hypersensitivity reactions, including anaphylaxis. Appropriate medical treatment and supervision must be available following administration of DENGVAXIA.
Vaccination with DENGVAXIA may not protect all individuals. It is recommended to continue personal protection measures against mosquito bites after vaccination.
Syncope (fainting) can occur following, or even before, vaccination with DENGVAXIA as a psychogenic response to injection with a needle. Procedures should be in place to prevent injury from falling and to manage syncopal reactions.
DENGVAXIA has not been evaluated for carcinogenic or mutagenic potential or impairment of male fertility. Exposure of female rabbits to DENGVAXIA prior to and during gestation did not impair fertility. [See Use In Specific Populations]
There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to DENGVAXIA during pregnancy. Women who receive DENGVAXIA during pregnancy are encouraged to contact directly, or have their healthcare professional contact, Sanofi Pasteur Inc. at 1-800-822-2463 (1-800-VACCINE) to enroll in or obtain information about the registry.
All pregnancies have a risk of birth defect, loss, or other adverse outcomes. In the US general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.
No specific studies of DENGVAXIA have been performed among pregnant women. A limited number of cases of inadvertent exposure during pregnancy were reported during clinical studies. Isolated adverse pregnancy outcomes (e.g., stillbirth, intrauterine death, spontaneous abortion, blighted ovum) have been observed for these exposed pregnancies, with similar frequency and nature in the vaccinated individuals compared to the control group, and with risk factors identified for all cases. Available data in pregnant women are not sufficient to determine the effects of DENGVAXIA on pregnancy, embryo-fetal development, parturition and post-natal development.
In two developmental toxicity studies, the effect of DENGVAXIA on embryo-fetal and post-natal development was evaluated in pregnant rabbits and mice. A developmental toxicity study was performed in female rabbits given a 5 log10 50% cell culture infectious dose (CCID50) of DENGVAXIA (full human dose ranging from 4.5 log10 to 6.0 log10 CCID50) by intravenous injection prior to mating and during gestation. The study revealed no evidence of harm to the fetus due to DENGVAXIA. In another study, female mice were administered a single dose of 5 log10 CCID50, 6.5 log10 CCID50 (about 3 times the highest human dose) or 8 log10 CCID50 (about 100 times the highest human dose) of DENGVAXIA by intravenous injection during gestation. Fetal toxicities were observed at maternally toxic doses. [See Animal Data.]
Disease-associated maternal and/or embryo/fetal risk
Pregnant women are at increased risk of complications associated with dengue infection compared to non-pregnant women. Pregnant women with dengue may be at increased risk for adverse pregnancy outcomes, including preterm labor and delivery. Vertical transmission of dengue virus from mothers with viremia at delivery to their infants has been reported.
Fetal/neonatal adverse reactions
Vaccine viremia can occur 7 to 14 days after vaccination with a duration of <7 days [See Pharmacokinetics.]. The potential for transmission of the vaccine virus from mother to infant is unknown.
In two developmental toxicity studies, the effect of DENGVAXIA on embryo-fetal and post-natal development was evaluated in pregnant rabbits and mice.
Rabbits were administered a full human dose [0.5 mL (5 log10 CCID50/animal/occasion)] of DENGVAXIA by intravenous injection 30 and 10 days before mating and on Days 6, 12 and 27 during gestation. No vaccine-related fetal malformation or variations and adverse effects on female fertility or pre-weaning development were reported in this study. Pregnant mice were administered a single dose of either 5 log10 CCID50 (full human dose ranging from 4.5 log10 to 6.0 log10 CCID50), 6.5 log10 CCID50 (about 3 times the highest human dose) or 8 log10 CCID50 (about 100 times the highest human dose) of DENGVAXIA by intravenous injection on Day 6, 9 or 12 of gestation. At doses of 6.5 log10 CCID50 or 8 log10 CCID50 of DENGVAXIA, maternal toxicity was observed which was associated with increased post-implantation loss and at doses of 8 log10 CCID50 with reduced fetal body weight. The significance of this observation for humans is unknown, especially considering the different route of administration (the human route of administration is subcutaneous) and dose levels which exceeded the intended human dose. There were no vaccine related fetal malformations or other evidence of teratogenesis noted in this study.
Human data are not available to assess the impact of DENGVAXIA on milk production, its presence in breast milk, or its effects on the breastfed child. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for DENGVAXIA and any potential adverse effects on the breastfed child from DENGVAXIA or from the underlying maternal condition. For preventive vaccines, the underlying condition is susceptibility to disease prevented by the vaccine. A lactation study in which female mice were administered a single dose of DENGVAXIA on day 14 of lactation did not show the presence of DENGVAXIA in breast milk.
Disease-associated maternal and/or embryo/fetal risk
Vertical transmission of dengue virus, including potentially through breastmilk, has been reported.
Fetal/neonatal adverse reactions
Vaccine viremia can occur 7 to 14 days after vaccination with a duration of <7 days. [See Pharmacokinetics] The potential for transmission of the vaccine virus from mother to infant through breastmilk is unknown.
A developmental toxicity study in which female mice were administered a single injection of 5 log10 CCID50 (full human dose ranging from 4.5 log10 to 6.0 log10 CCID50), 6.5 log10 CCID50 or 8 log10 CCID50 of DENGVAXIA by intravenous injection on Day 14 of lactation did not show the presence of DENGVAXIA in breast milk in mice when measured 24 hours after vaccine administration.
Safety and effectiveness of DENGVAXIA in children younger than 9 years of age have not been established.
Safety and effectiveness of DENGVAXIA in adults 65 years of age and older have not been established.
No Information Provided
Do not administer DENGVAXIA to individuals with a history of severe allergic reaction to a previous dose of DENGVAXIA or to any component of DENGVAXIA. [See DESCRIPTION]
Do not administer DENGVAXIA to individuals with severe immunodeficiency or immunosuppression due to disease or therapy.
Following administration, DENGVAXIA elicits dengue-specific immune responses against the four dengue virus serotypes. The exact mechanism of protection has not been determined.
In studies that evaluated the occurrence of vaccine viremia systematically at pre-specified time-points, vaccine viremia (measured by genomic amplification methods) was observed following vaccination with DENGVAXIA in 5.6% of subjects, with 90% of these occurrences documented after the first injection. Vaccine viremia was observed 7 to 14 days after DENGVAXIA vaccination with a duration of <7 days.
The efficacy of DENGVAXIA was evaluated in two randomized, observer-blind, placebo-controlled, multi-center studies. Study 1 (N=20,869) was conducted in individuals 9 through 16 years of age in four Latin American countries and Puerto Rico; and Study 2 (N=10,275) was conducted in individuals 2 through 14 years of age in five Asia-Pacific countries. A subset of subjects in each study (10% in Study 1; 20% in Study 2) was evaluated for antibodies to dengue virus at the time of enrollment and at later time points. Both studies enrolled subjects irrespective of evidence of previous dengue infection. Subjects were randomized 2:1 to receive either DENGVAXIA or saline placebo and were monitored for symptomatic virologically-confirmed dengue (VCD) starting at Day 0. Per protocol vaccine efficacy was assessed beginning 28 days after the third vaccination for 12 months. VCD was defined as an acute febrile illness (temperature ≥38°C on at least 2 consecutive days) virologically-confirmed by dengue RT-PCR and/or dengue non-structural protein 1 (NS1) ELISA Antigen Test. For each study, in pre-specified vaccine efficacy analyses including the full age range of subjects enrolled, the pre-specified criterion for demonstrating efficacy of DENGVAXIA against VCD due to any dengue virus serotype and irrespective of previous dengue virus infection, was met (lower bound of 95% CI for vaccine efficacy >25%). These studies were not designed to demonstrate efficacy of DENGVAXIA against individual dengue serotypes.
Given the identification of the increased risk for severe dengue following vaccination with DENGVAXIA and subsequent infection with dengue virus in persons not previously infected with dengue virus [see ADVERSE REACTIONS], Table 3 presents analyses of vaccine efficacy against VCD due to any dengue virus serotype, limited to subjects who had baseline sera evaluated and who were dengue seropositive at baseline. These analyses include subjects 9 through 16 years of age from Study 1 and subjects 9 through 14 years of age from Study 2.
