Study Design

TIDES: Study design

TIDES: Tetravalent Immunisation against Dengue Efficacy Study in Healthy Children 2,3

  • TIDES is a pivotal, ongoing, multinational, double-blind, randomised, placebo-controlled, Phase 3 study evaluating the efficacy, safety and immunogenicity of QdengaTM against dengue fever 1-3
  • 20,071 healthy participants aged 4-16 years from 8 dengue-endemic countries were given at least one dose of the vaccine or placebo 1-3
    • Brazil, Colombia, Dominican Republic, Nicaragua, Panama, Philippines, Sri Lanka and Thailand
    • Balanced enrolment between Asia-Pacific (46.5%) and Latin America (53.5%)
  • Both dengue-naïve and previously exposed individuals were included in TIDES
    • At baseline, 27.7% of trial participants were seronegative for all four dengue serotypes 2,3
  • Exclusion criteria included baseline febrile illness, impaired/altered immune function, hypersensitivity to any vaccine component, pregnancy/breastfeeding, previous receipt of dengue vaccine, and other protocol violations as per trial criteria 2,3

§ The safety subpopulation includes participants who were randomly selected for additional safety and immunogenicity assessments

* One 0.5 mL dose of QdengaTM contained approximately 3.6, 4.0, 4.6 and 5.1 log10 plaque-forming units of DENV-1, DENV-2, DENV-3, and DENV-4 strains, respectively; the placebo was 0.5 mL of saline. [BIS19] Four patients received both vaccine and placebo because of administrative errors; these participants are not included in the total.

Efficacy

TIDES: Efficacy data

TIDES: Tetravalent Immunisation against Dengue Efficacy Study in Healthy Children

The clinical efficacy of QdengaTM was assessed in TIDES, a pivotal Phase 3, double-blind, randomised, placebo-controlled study of 20,099 healthy children aged 4 to 16 years 1-3

QdengaTM effectively prevented virologically confirmed dengue (VCD) in the majority of cases 1-4

The primary endpoint in TIDES was met: QdengaTM demonstrated 80.2% overall vaccine efficacy in preventing VCD induced by any dengue serotype from 30 days to 12 months after the second dose (95% CI: 73.3%–85.3%; p<0.001) 1,2 61/12,700 (0.5%) VCD cases in the QdengaTM group vs 149/6,316 (2.4%) cases in the placebo group 1,2

Exploratory analysis

info

Exploratory analysis

Exploratory analysis found efficacy against DENV-1 of 72.0% (seropositive, 95% CI: 52.2–83.6) and 67.8% (seronegative, 40.3–82.6), and DENV-2 of 93.7% (seropositive, CI 86.1–97.1) and 98.1% (seronegative, CI 85.8–99.7); 

Analysis was not possible for DENV-4, with only one patient being seronegative at baseline. Efficacy against DENV-3 varied by baseline serostatus: 61.8% (seropositive, 95% CI: 43.0 to 74.4) and -68.2% (seronegative, 95% CI: 318.9 to 32.4); vaccine efficacy was not shown in individuals who were seronegative2

test

Two secondary endpoints were not met, largely due to the small number of cases: 3

  • Efficacy against dengue serotype 4
  • Efficacy against severe VCD (Dengue Case Adjudication Committee criteria)
test

Data currently suggests a lack of efficacy against DENV-3 infection in baseline seronegative participants, and there is no evidence of disease enhancement. 1,3

 

Efficacy of QdengaTM in people over 17 years of age

The clinical efficacy of Qdenga™ in individuals aged from 17 years of age is based on bridging of immunogenicity data 1

  • Immunogenicity of QdengaTM in adults aged 18 to 60 years was assessed in DEN-304, a double-blind, randomised, placebo-controlled Phase 3 study in a non-endemic country (US) 1
  • 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 TIDES and DEN-304 1
  • Protection against dengue disease is expected in adults although the actual magnitude of efficacy relative to that observed in children and adolescents is unknown 1

Safety Profile

TIDES: Safety data

TIDES: Tetravalent Immunization against Dengue Efficacy Study in Healthy Children 2,3

Qdenga™ has been generally well-tolerated to date in TIDES 1-4

In TIDES: 

  • No important safety risks were identified in TIDES up to 4.5 years after the second dose of QdengaTM 4
  • Similar cumulative incidences of serious AEs were observed for individuals treated with QdengaTM and placebo 3
    • Up to 18 months after the second dose: 4.0% vs 4.8%, respectively
    • Consistent with expected medical disorders in study population 3
  • No evidence to date that QdengaTM enhanced disease severity in seronegative individuals 5
    • Serious AEs occurred at 4.3% for both seropositive patients (624/14,520) and seronegative individuals (238/5,547) up to 18 months after the second dose 1,3

 

Overall clinical safety of QdengaTM

The overall safety profile for QdengaTM is based on a pooled analysis of 14,627 participants aged 4-60 years (13,839 children and 788 adults) who have been vaccinated with QdengaTM, including a reactogenicity subset of 3,830 participants (3,042 children and 788 adults)1

  • The most frequently reported reactions in subjects 4 to 60 years of age were injection site pain (50%), headache (35%), myalgia (31%), injection site erythema (27%), malaise (24%), asthenia (20%) and fever (11%)1
  • These adverse reactions usually occurred within 2 days after the injection, were mild to moderate in severity, had a short duration (1 to 3 days) and were less frequent after the second injection of QdengaTM than after the first injection1
  • Frequency, type and severity of adverse reactions in children were largely consistent with those in adults1
  • In clinical study DEN-205, transient vaccine viraemia was observed after vaccination with QdengaTM in 49% of study participants who were dengue-naïve and in 16% of study participants who had been infected with dengue before. Vaccine viraemia usually started in the second week after the first injection and had a mean duration of 4 days. Vaccine viraemia was associated with transient, mild to moderate symptoms, such as headache, arthralgia, myalgia and rash in some subjects. Vaccine viraemia was rarely detected after the second dose.1
