简要总结
The aim of this study was to evaluate the administration of CYD dengue vaccine serotypes (1, 2, 3 and 4) following a compressed schedule in 3 different populations.
Primary Objectives:
- To describe the humoral immune response to each of the 4 parental dengue virus serotypes at baseline and 28 days after CYD dengue vaccine Dose 3 in Group 1 (Month [M] 13) and Group 2 (M07), irrespective of whether or not Yellow Fever (YF) vaccine has been previously administered.
- To describe the persistence of the humoral immune response to each of the 4 parental dengue virus serotypes 6 months after CYD dengue vaccine Dose 3 in Group 1 (M18) and Group 2 (M12), irrespective of whether or not YF vaccine has been previously administered.
Secondary Objective:
- To describe the humoral immune response to each of the 4 parental dengue virus serotypes at baseline and 28 days after CYD dengue vaccine Dose 1 and Dose 2 in Groups 1 and 2, irrespective of whether or not YF vaccine has been previously administered.
- To describe the humoral immune response to each of the 4 parental dengue virus serotypes at baseline and 28 days after CYD dengue Dose 1 in the combined YF-participants in Group 1 (N=60) and Group 2 (N=60), and in Group 3 (N=120).
- To describe by FV status at baseline the humoral immune response to each of the 4 parental dengue virus serotypes at baseline and 28 days after each injection of CYD dengue vaccine in Groups 1, 2, and 3.
- To describe the safety profile after each injection of CYD dengue vaccine and/or YF vaccine.
详细描述
Participants were randomized to 4 different groups to receive either CYD dengue vaccine and/or YF vaccine. Participants who already received YF vaccine prior to enrolment were randomized to one of the 2 groups receiving CYD dengue vaccine alone. Participants were evaluated for immunogenicity, antibody persistence, reactogenicity and safety.

- •For participants classified as YF positive (+) to be included in Groups 1 and 2, previous vaccination (3 months to 10 years) with YF vaccine confirmed by acceptable documentation.
排除标准
- •Participant was pregnant, or lactating, or of childbearing potential (to be considered of non-childbearing potential, a female must be post-menopausal for at least 1 year, surgically sterile, or using an effective method of contraception or abstinence from at least 4 weeks prior to the first vaccination and until at least 4 weeks after the last vaccination)
- •Participation in the 4 weeks preceding the first trial vaccination, or planned participation during the present trial period, in another clinical trial investigating a vaccine, drug, medical device, or medical procedure
- •Receipt of any vaccine in the 4 weeks preceding the first trial vaccination or planned receipt of any vaccine in the 4 weeks following each trial vaccination
- •For all participants classified as YF negative (-), any previous vaccination against Flavivirus (FV) diseases (including Japanese Encephalitis [JE], tick-borne encephalitis, and YF)
- •For participants classified as YF+, previous vaccination against FV diseases except YF (including JE and tick-borne encephalitis)
- •For all participants, any FV vaccination planned during the trial period outside the study protocol
- •Receipt of immune globulins, blood or blood-derived products in the past 3 months
- •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)
- •Self-reported seropositivity for human immunodeficiency virus (HIV), hepatitis B, or hepatitis C
- •Self-reported history of FV infection (e.g., JE, Dengue, YF, West Nile), confirmed either clinically or serologically
- •Known systemic hypersensitivity to any of the vaccine components, or history of a life-threatening reaction to the vaccine(s) used in the trial or to a vaccine containing any of the same substances, including dry natural latex
- •Deprived of freedom by an administrative or court order, or in an emergency setting, or hospitalized involuntarily
- •Current alcohol abuse or drug addiction
- •Chronic illness that, in the opinion of the investigator, is at a stage where it might interfere with trial conduct or completion

- •Moderate or severe acute illness/infection (according to investigator judgment) on the day of vaccination or febrile illness (temperature >= 38.0°C [>=100.4°F]). A prospective participant should not be included in the study until the condition has resolved or the febrile event has subsided
- •Previous residence (> 12 months) in, or travel in the last 30 days to FV endemic regions
- •History of thymic pathology (thymoma), thymectomy, or myasthenia.

Geometric Mean Titers (GMTs) of Antibodies Against Each Dengue Virus Serotype Following Injection (Inj.) With CYD Dengue Vaccine Dose 3: Group 1 and Group 2
时间窗: Pre-injection 1, 28 days and 6 months post-injection 3
GMTs of antibodies against each dengue virus serotype (parental strain) was assessed using the dengue plaque reduction neutralization test (PRNT).
