Immunogenicity and Safety of a Tetravalent Dengue Vaccine Administered Concomitantly or Sequentially With Cervarix®

Immunogenicity and Safety of a Tetravalent Dengue Vaccine Administered Concomitantly or Sequentially With Cervarix® in Healthy Female Subjects Aged 9 to 14 Years in Mexico

The aim of this study was to investigate the immunogenicity and safety of CYD dengue vaccine and Cervarix when administered concomitantly or sequentially in healthy female participants aged 9-14 years of age.

Primary objectives:

• To demonstrate that the humoral immune response (in terms of geometric mean titers [GMTs]) to Cervarix after concomitant administration with the CYD dengue vaccine is non-inferior to the humoral immune response (in terms of GMTs) after sequential administration with the CYD dengue vaccine measured 28 days after the last dose of Cervarix.
• To demonstrate that the humoral immune response (in terms of GMTs) to the CYD dengue vaccine after concomitant administration with Cervarix is non-inferior to the humoral immune response (in terms of GMTs) to the CYD dengue vaccine after sequential administration with Cervarix measured 28 days after the last dose of the CYD dengue vaccine.

Secondary Objectives:

• To demonstrate that the humoral immune response (in terms of seroconversion) to Cervarix after concomitant administration with the CYD dengue vaccine is non-inferior to the humoral immune response (in terms of seroconversion) to Cervarix sequential administration with the CYD dengue vaccine measured 28 days after the last dose of Cervarix.
• To describe the humoral immune response to Cervarix at baseline and after each dose of Cervarix in each and any group.
• To describe the humoral immune response to the CYD dengue vaccine at baseline and after each dose of the CYD dengue vaccine, in each and any group.
• To describe the safety of Cervarix and CYD dengue vaccine after each and any dose in each group.

Study Overview

• Status: Completed
• Conditions: Dengue Fever; Dengue Hemorrhagic Fever; Human Papillomavirus Disease
• Intervention / Treatment: Biological: CYD Dengue Vaccine; Biological: CYD Dengue Vaccine; Biological: Human Papillomavirus Bivalent [Types 16 and 18] Vaccine, Recombinant

Detailed Description

Participants received 3 doses of the CYD dengue vaccine and 2 doses of Cervarix administered either concomitantly or sequentially. Due to a protocol amendment, only previously dengue exposed participants (seropositive for dengue before vaccination) were eligible to complete the vaccination schedule and be assessed for CYD immunogenicity and human papilloma virus (HPV) immunogenicity. Dengue unexposed participants (seronegative for dengue before vaccination) did not receive the third CYD dengue vaccine injection, but were followed for safety up to 6 months after the last injection.

Safety assessments included solicited reactions within 7 or 14 days after each injection, unsolicited adverse events within 28 days after each injection, and serious adverse events during the study period. All participants were included in the assessment of safety up to 6 months after the last injection.

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Geometric Mean Titers (GMTs) Against Each Cervarix Human Papillomavirus (HPV) Antigen (HPV-16 and HPV-18) 28 Days After Last Cervarix Vaccination in the Previously Dengue Seropositive Participants	GMTs against each Cervarix HPV antigen (HPV-16 and HPV-18) were assessed using an enzyme-linked immunosorbent assay (ELISA) method. Dengue seropositive participants at baseline were defined as those participants with titers greater than or equal to (>=) 10 (1/dilutions [dil]) for at least one serotype with the parental dengue virus strain.	28 days after the last Cervarix vaccination
GMTs Against Each Dengue Virus Serotype 28 Days After the Third CYD Dengue Vaccination in the Previously Dengue Seropositive Participants	The GMTs against each of the four parental dengue virus serotypes (Serotypes 1, 2, 3, and 4) of CYD dengue vaccine were assessed using the 50% plaque reduction neutralization test (PRNT50) assay. Dengue seropositive participants at baseline were defined as those participants with titers >=10 (1/dil) for at least one serotype with the parental dengue virus strain.	28 days after third CYD dengue vaccination

Secondary Outcome Measures

Up to 7 days after any and each vaccination
Number of Participants Reporting Serious Adverse Events (SAEs) Including Serious AESIs Following Vaccination With Cervarix or CYD Dengue Vaccine	An SAEs were AEs resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly or a medically important event.

Number of Participants Reporting Cases of Virologically Confirmed Dengue (VCD) Hospitalization Following Vaccination With Cervarix or CYD Dengue Vaccine	Hospitalized suspected dengue case was defined as an acute febrile illness with diagnosis of dengue requiring hospitalization (with bed attribution). In such cases, 1 unplanned acute blood sample (within the first 5 days after fever onset) was collected for virological confirmation of hospitalized suspected dengue case. A suspected case was considered VCD if there was a detection of wild type dengue virus by dengue non-structural protein 1 antigen ELISA and/or dengue reverse transcriptase-polymerase chain reactions.	From Day 0 up to 6 months after the last CYD or Cervarix vaccination
