NCT03423173

Brief Summary

The purpose of this study is to investigate lot-to-lot consistency in terms of equivalence of the immune responses induced by 3 consecutive TDV lots in healthy participants aged 18 to 60 years in non-endemic country(ies) for dengue.

Outcome Measures

Primary Outcomes (1)

  • Geometric Mean Titers (GMTs) of Neutralizing Antibodies for Each of the 4 Dengue Serotypes at Day 120 in the Immunogenicity Subset

    GMTs of neutralizing antibodies for each of the 4 Dengue Serotypes was measured by microneutralization test 50% \[MNT50\]. The 4 dengue virus serotypes were DENV-1, DENV-2, DENV-3 and DENV-4.

    1 month post second dose (Day 120)

Secondary Outcomes (7)

  • Percentage of Participants Who Are Seropositive for Each of the 4 Dengue Serotypes at Days 120 and 270 in the Immunogenicity Subset

    1 month post second dose (Day 120) and 6 months post second dose (Day 270)

  • GMTs of Neutralizing Antibodies for Each of the 4 Dengue Serotypes at Day 270 in the Immunogenicity Subset

    6 months post second dose (Day 270)

  • Percentage of Participants With Solicited Local (Injection Site) Adverse Events (AEs) by Severity After Each Vaccination

    Within 7 Days of each Vaccination (day of vaccination + 6 days)

  • Percentage of Participants With Solicited Systemic Adverse Events (AEs) by Severity After Each Vaccination

    Within 14 Days of each Vaccination (day of vaccination + 13 days)

  • Percentage of Participants With Any Unsolicited Adverse Events (AEs) After Each Vaccination

    Within 28 days (day of vaccination + 27 days) after each vaccination

  • +2 more secondary outcomes

  • Chronic use of oral steroids (equivalent to 20 mg/day prednisone ≥12 weeks/≥2 mg/kg body weight/day prednisone ≥2 weeks) within 60 days prior to Day 1 (M0) (use of inhaled, intranasal, or topical corticosteroids is allowed)
  • Receipt of parenteral steroids (equivalent to 20 mg/day prednisone ≥12 weeks/≥ 2 mg/kg body weight/day prednisone ≥2 weeks) within 60 days prior to Day 1 (M0).
  • Administration of immunoglobulins and/or any blood products within the 3 months prior to Day 1 (M0) or planned administration during the trial.
  • Receipt of immunostimulants within 60 days prior to Day 1 (M0).
  • Hepatitis C virus infection.
  • Genetic immunodeficiency.
  • Has abnormalities of splenic or thymic function.
  • Has a known bleeding diathesis, or any condition that may be associated with a prolonged bleeding time.
  • Has any serious chronic or progressive disease according to judgment of the Investigator (e.g., neoplasm, insulin dependent diabetes, cardiac, renal or hepatic disease).
  • Has body mass index (BMI) greater than or equal to 35 kg/m\^2 (= weight in kg/\[height in meters\^2\]).
  • Has history of substance or alcohol abuse within the past 2 years.
  • +2 more criteria
