Trial Outcomes & Findings for Study of Sanofi Pasteur's CYD Dengue Vaccine in Healthy Subjects in Singapore (NCT NCT00880893)

NCT ID: NCT00880893

Last Updated: 2022-03-21

Results Overview

Seropositivity against each dengue virus serotype (parental strains) was assessed using a dengue plaque reduction neutralization test (PRNT) assay. Seropositive participants were defined as participants with neutralizing antibody titers \>=10 (1/dilution).

PRIMARY outcome

Timeframe: Pre-Injection 1, 2, and 3 and 28 days Post-Injection 1, 2, and 3

Population: Analysis was performed on Per-Protocol (PP) analysis set which included all participants who were vaccinated and had no protocol deviations. Here, 'number analyzed' = participants with available data for each specified category.

Seropositivity against each dengue virus serotype (parental strains) was assessed using a dengue plaque reduction neutralization test (PRNT) assay. Seropositive participants were defined as participants with neutralizing antibody titers \>=10 (1/dilution).

PRIMARY outcome

Timeframe: Pre-Injection 1 and 28 days Post-Injection 3

Population: Analysis was performed on Per-Protocol analysis set. Here, 'overall number of participants analyzed' = participants evaluable for this outcome measure and 'number analyzed' = participants with available data for each specified category.

Seropositivity against at least 1, 2, 3, or 4 dengue virus serotypes (parental strains) was assessed using a dengue PRNT assay. Seropositive participants were defined as participants with neutralizing antibody titers \>=10 (1/dilution).

Timeframe: Pre-Injection 1, 28 days Post-Injection 3, at 1 year follow up, 2 year follow up, 3 year follow up and 4 year follow up (assessed post-injection 3 during the follow up duration of 4 years)

Population: Full analysis set included participants who received at least 1 dose of CYD dengue vaccine or Placebo, had at least 1 blood sample drawn and valid post-vaccination serology result. Here, 'overall number of participants analyzed'=participants evaluable for outcome measure and 'number analyzed'=participants with available data for specified category.

Seropositivity against each dengue virus serotypes (parental strains) was assessed using a dengue PRNT assay. Seropositive participants were defined as participants with neutralizing antibody titers \>=10 (1/dilution).

SECONDARY outcome

Timeframe: Pre-Injection 1, 28 days Post-Injection 3, at 1 year follow up, 2 year follow up, 3 year follow up and 4 year follow up (assessed post-injection 3 during the follow up duration of 4 years)

Population: Analysis was performed on Full analysis set. Here, 'overall number of participants analyzed' = participants evaluable for this outcome measure and 'number analyzed' = participants with available data for each specified category.

Seropositivity against at least 1, 2, 3, or 4 dengue virus serotypes was assessed using a dengue PRNT assay. Seropositive participants were defined as participants with neutralizing antibody titers \>=10 (1/dilution).

Timeframe: 28 days Post-Injection 3, at 1 year follow up, 2 year follow up, 3 year follow up and 4 year follow up (assessed post-injection 3 during the follow up duration of 4 years)

Population: Analysis was performed on Full analysis set. Here, 'overall number of participants analyzed' = participants evaluable for this outcome measure and 'number analyzed' = participants with available data for each specified category.

Seropositivity against each serotype with the dengue virus strain were assessed using a dengue PRNT assay. Seropositive participants were defined as participants with antibody titers \>=10 (1/dilution). Dengue participants immune at baseline was defined as those participants with titers \>=10 (1/dilution) against at least one dengue serotype at baseline.

Population: Analysis was performed on Full analysis set. Here, 'overall number of participants analyzed' = participants evaluable for this outcome measure and 'number analyzed' = participants with available data for each specified category.

Seropositivity against each serotype with the dengue virus strain were assessed using a dengue PRNT assay. Seropositive participants were defined as participants with neutralizing antibody titers \>=10 (1/dilution). Dengue participants immune at baseline was defined as those participants with titers \>=10 (1/dilution) against at least one dengue serotype at baseline.
