NCT01134263

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.

Outcome Measures

Primary Outcomes (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

    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.

    28 days post-injection 3

Secondary Outcomes (3)

  • 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

  • Number of Participants With Solicited Injection Site Reactions After Any Vaccination

    7 days post any vaccination

  • Number of Participants With Solicited Systemic Reactions After Any Vaccination

    14 days post any vaccination

Age GroupsAdult (18-64)

You may qualify if:

  • Informed consent form was signed and dated.
  • Able to attend all scheduled visits and to comply with all trial procedures.
  • For a woman of childbearing potential, use of an effective method of contraception, or abstinence from at least 4 weeks prior to the first vaccination until at least 4 weeks after the last vaccination (i.e., for 14 months).

You may not qualify if:

  • Known pregnancy, or a positive urine pregnancy test.
  • History of flavivirus infection or vaccination or prolonged habitation in a dengue endemic area.
  • Currently breastfeeding a child.
  • Participation in another clinical trial investigating a vaccine, drug, medical device, or medical procedure in the 4 weeks preceding the first trial vaccination.
  • Planned participation in another clinical trial during the present trial period.
  • Planned receipt of any vaccine in the 4 weeks following any trial vaccination, except for pandemic influenza vaccination.
  • Receipt of blood or blood-derived products in the past 3 months, which might interfere with assessment of the immune response.
  • Known or suspected congenital or acquired immunodeficiency; or receipt of immunosuppressive therapy such as anti-cancer chemotherapy or radiation therapy within the preceding 6 months; or long-term systemic corticosteroid therapy (prednisone or equivalent for more than 2 consecutive weeks within the past 3 months).
