Study Details

Study Description

Brief Summary

The purpose of this study was to demonstrate that different CYD dengue vaccine lots manufactured using the same method and in the same location but at different times produce an equivalent immunological response after 3 doses.

Primary Objective

  • To demonstrate that three different Phase III lots of CYD dengue vaccine induce an equivalent immune response in terms of post-Dose 3 geometric mean titers (GMTs) against the four parental serotypes.
Secondary Objectives:
  • To demonstrate that data from one Phase II lot and pooled data from Phase III lots of CYD dengue vaccine show an equivalent immune response in terms of post-Dose 3 GMTs against the four parental serotypes.

  • To describe the safety of the CYD dengue vaccine in all participants after each dose.

Detailed Description

  • Outcome Measures

    Primary Outcome Measures

    1. Post-Dose 3 Geometric Mean Titers (GMTs) of Antibodies Against Each of the Four Dengue Virus Serotypes Following Vaccination With Phase III Lots of CYD Dengue Vaccine [28 days post-injection 3]

      GMTs against each of the 4 serotypes (serotype 1, serotype 2, serotype 3 and serotype 4) of dengue virus strains were assessed using the plaque reduction neutralization test (PRNT) assay. The lot-to-lot consistency between 3 Phase III lots was based on the use of the two-sided 95% confidence interval (CI) of the differences of the means of the log10 transformed post-vaccination titers between pairs of lots.

    Secondary Outcome Measures

    1. Geometric Mean Titers of Antibodies Against Each of the Four Dengue Virus Serotypes Following Vaccination With Pooled Phase III Lots (1, 2 or 3 )and Phase II Lot of CYD Dengue Vaccine [28 days post-Injection 3]

      GMTs against each of the 4 serotypes (serotype 1, serotype 2, serotype 3 and serotype 4) of dengue virus strains were assessed using PRNT assay. Equivalence of Phase III vaccine with Phase II vaccine was assessed by Bridging between Phase III and Phase II Lot of CYD Dengue Vaccine.

    2. Number of Participants With Solicited Injection Site Reactions After Any Vaccination [7 days post any vaccination]

      Solicited injection site reactions: Pain, Erythema, and Swelling. Pain: Grade 3: Significant; prevents daily activity. Erythema and Swelling: Grade 3: > 10 cm. Participants with Injection Site Reactions of any Grade (1, 2 or 3) and grade 3 were reported.

    3. Number of Participants With Solicited Systemic Reactions After Any Vaccination [14 days post any vaccination]

      Solicited systemic reactions: Asthenia, Fever, Headache, Malaise and Myalgia. Fever: Grade 3: >=39.0°C (>=102.1°F). Headache, malaise, myalgia and asthenia: Grade 3: significant; prevents daily activity. Participants with systemic reactions of any Grade (1, 2 or 3) and grade 3 were reported.
