NCT03342898

Brief Summary

The main purpose of this study is to assess the immunogenicity and safety of the concomitant and sequential administration of yellow fever (YF) vaccine and tetravalent dengue vaccine (TDV) in healthy participants aged 18 to 60 years living in country non-endemic for both dengue and YF.

Outcome Measures

Primary Outcomes (1)

  • Percentage of Participants Who Are YF and Dengue Virus (DENV)-Naive at Baseline and Are Seroprotected Against YF on Day 30 as Measured by Plaque Reduction Neutralization Test (PRNT)

    Seroprotection was defined as reciprocal anti-YF neutralizing antibody titer ≥10. Immunological naivety to YF and DENV was defined as Baseline reciprocal neutralizing antibody titers \<10 for YF and for the 4 dengue serotypes. The 95% CI was calculated using exact Clopper-Pearson method.

    Day 30

Secondary Outcomes (11)

  • Geometric Mean Titers (GMTs) of Neutralizing Antibodies for Each of the 4 Dengue Serotypes on Days 30, 90, 120, 180 and 210 in Participants YF and DENV-naive at Baseline

    Pre-second and -third vaccination (Days 90 and 180, respectively); and 1 month post -first, second, and third vaccination (Days 30, 120, and 210, respectively)

  • Percentage of Participants Who Are Seropositive for Each of the 4 Dengue Serotypes on Days 30, 90, 120, 180 and 210 in Participants YF and DENV-naive at Baseline

    Pre-second and -third vaccination (Days 90 and 180, respectively); and 1-month post -first, -second, and -third vaccination (Days 30, 120, and 210, respectively)

  • Percentage of Participants Who Are Seropositive for Multiple (2, 3 or 4) Dengue Serotypes on Days 30, 90, 120, 180 and 210 in Participants YF and DENV-naive at Baseline

    Pre-second and -third vaccination (Days 90 and 180, respectively); and 1-month post -first, second, and -third vaccination (Days 30, 120, and 210, respectively)

  • Percentage of YF and DENV-naive Participants at Baseline Who Are Seroprotected Against YF on Day 210 as Measured by PRNT

    1-month post third vaccination (Day 210)

  • Geometric Mean Titers (GMTs) of Anti-YF Neutralizing Antibodies at Day 30 in Participants YF and DENV-Naive at Baseline

    1-month post-first vaccination (Day 30)

  • +6 more secondary outcomes

  • Has contraindications, warnings and/or precautions to vaccination with the YF-17D vaccine as specified within the product information (especially history of thymus dysfunction).
  • Female participant who are pregnant or breastfeeding
  • Has any history of progressive or severe neurologic disorder, seizure disorder or neuro-inflammatory disease (e.g., Guillain-Barre syndrome) or suspected impairment/alteration of immune function.
  • Has body mass index (BMI) greater than or equal to 35 kg/m\^2 (=weight in kg/\[height in meters\^2\]).
  • Is intent to travel to dengue or YF endemic countries during the trial period.
  • Has received any other vaccines within 14 days (for inactivated vaccines) or 28 days (for live vaccines) prior to enrollment in this trial or who are planning to receive any non-trial vaccine within 28 days of trial vaccine administration.
  • Has previous and planned vaccination (during the trial conduct), against any flavivirus including dengue, YF, Japanese encephalitis (JE) or tick-borne encephalitis viruses.
  • Has previous participation in any clinical trial of a dengue or other flavivirus (e.g., West Nile \[WN\] virus) candidate vaccine, except for participants who received placebo in those trials.

IPD Sharing
Will share

Takeda makes patient-level, de-identified data sets and associated documents available for all interventional studies after applicable marketing approvals and commercial availability have been received (or program is completely terminated), an opportunity for the primary publication of the research and final report development has been allowed, and other criteria have been met as set forth in Takeda's Data Sharing Policy (see www.TakedaClinicalTrials.com for details). To obtain access, researchers must submit a legitimate academic research proposal for adjudication by an independent review panel, who will review the scientific merit of the research and the requestor's qualifications and conflict of interest that can result in potential bias. Once approved, qualified researchers who sign a data sharing agreement are provided access to these data in a secure research environment.
