Study Details

Study Description

Brief Summary

The aim of the study was to assess and describe the booster effect of a CYD dengue vaccine dose administered 4 to 5 years after the completion of a 3-dose vaccination schedule.

Primary Objective

  • To demonstrate the non-inferiority, in terms of geometric mean of titer ratios (GMTRs), of a CYD dengue vaccine booster compared to the third CYD dengue vaccine injection in participants from CYD13 - NCT00993447 and CYD30 - NCT01187433 trials (participants from Group 1 only).
Secondary Objectives:
  • If the primary objective of non-inferiority was achieved: To demonstrate the superiority, in terms of GMTRs, of a CYD dengue vaccine booster compared to the third CYD dengue vaccine injection in participants from CYD13 and CYD30 trials.

  • To describe the immune responses elicited by a CYD dengue vaccine booster and placebo injection in participants who received 3 doses of the CYD dengue vaccine in the CYD13 and CYD30 trials in all participants.

  • To describe the neutralizing antibody levels of each dengue serotype post-dose 3 (CYD13 and CYD30 participants) and immediately prior to booster or placebo injection in all participants.

  • To describe the neutralizing antibody persistence 6 months, 1 year, and 2 years post booster or placebo injection in all participants.

  • To evaluate the safety of booster vaccination with the CYD dengue vaccine in all participants.

Condition or Disease Intervention/Treatment Phase
  • Biological: CYD Dengue Vaccine (5-dose formulation)
  • Biological: Placebo, NaCl 0.9%
Phase 2

Detailed Description

Healthy adolescents and adults who received 3 doses of the tetravalent dengue vaccine 4 to 5 years earlier in previous CYD dengue vaccine trials (CYD13 and CYD30) received either a booster dose CYD dengue vaccine or a placebo on Day 0. They were evaluated for safety and antibody persistence of the booster injection up to 2 years post-vaccination.

Adverse Events

Time Frame Adverse event (AE) data was collected from Day 0 (post-vaccination) up to 28 days post-booster injection. Solicited Reaction (SR) data was collected within 7 and 14 days after vaccination. Serious adverse event (SAE) data was collected throughout the study (up to 24 months after last vaccination).
Adverse Event Reporting Description Analysis was performed on Safety Analysis Set. A SR was an AE that was prelisted (i.e., solicited) in the electronic case report form (eCRF) and considered to be related to vaccination (adverse drug reaction). An unsolicited AE was an observed AE that did not fulfill the conditions prelisted (i.e., solicited) in the eCRF in terms of symptom and/or onset post-vaccination.
