Study Details
Study Description
Brief Summary
The purpose of the study is to demonstrate the non-inferiority (NI) of the immune response to 2 doses of 9vHPV vaccine, 1 co-administered with TDV, compared with 2 doses of 9vHPV vaccine administered alone.

Phase 3 |
Detailed Description
The vaccine being tested in this study is called Tetravalent Dengue Vaccine (TDV). The study will assess the immunogenicity and safety on the co-administration of 9vHPV vaccine with TDV in healthy participants aged ≥9 to <15 years.
The study will enroll approximately 614 healthy volunteers. Participants will be randomly assigned to one of the two treatment groups-
-
Group 1
-
Group 2
All participants will receive recombinant 9-valent Human Papillomavirus Vaccine (9vHPV) intramuscular (IM) in combination with Dengue Tetravalent Vaccine (TDV) subcutaneous (SC) injection on Day 1 (Month 0 ) followed by 9vHPV on Day 90 (Month 3) and TDV on Day 180 (Month 6) in Group 1. Participants will receive 9vHPV on Day 1 (Month 0) and Day 180 (Month 6) IM in Group 2.
This multi-center trial will be conducted in Thailand. The overall time to participate in this study is 12 months. Participants will make multiple visits to the clinic, after last dose of study drug for a follow-up assessment.

Outcome Measures
Primary Outcome Measures
- Geometric Mean Titers (GMTs) for Human Papillomavirus (HPV) Types 6, 11, 16, 18, 31, 33, 45, 52, 58 [Day 210 (Month 7)]
GMTs for HPV will be measured by immunoglobulin G binding assay (IgGBA) or equivalent assay.
Secondary Outcome Measures
- Percentage of Participants with Seropositivity for HPV Types 6, 11, 16, 18, 31, 33, 45, 52 and 58 as Measured by Immunoglobulin G Binding Assay (IgGBA) or Equivalent Assay [Day 210 (Month 7)]
Seropositivity for HPV is defined as an anti-HPV titer greater than or equal to the pre-specified serostatus cut-off for a given HPV type, measured by IgGBA.
- GMTs of Neutralizing Antibodies for Each of the 4 Dengue Serotypes [Day 120 (Month 4)]
GMTs of neutralizing antibodies for each of the 4 dengue serotypes will be measured by microneutralization test 50% (MNT50). The four dengue serotypes: DENV1, DENV2, DENV3 and DENV4.
- Percentage of Participants with Seropositivity for Each of the 4 Dengue Serotypes [Day 120 (Month 4)]
Seropositivity is defined as a reciprocal neutralizing antibody titer ≥10 for any of the 4 dengue serotypes. The four dengue serotypes: DENV1, DENV2, DENV3 and DENV4.
- Percentage of Participants with Seropositivity for Multiple (2, 3 or 4) Dengue Serotypes [Day 120 (Month 4)]
Seropositivity is defined as a reciprocal neutralizing antibody titer ≥10 for any of the 4 dengue serotypes. The four dengue serotypes: DENV1, DENV2, DENV3 and DENV4.
- Percentage of Participants with Solicited Local Reactions for 7 Days Following Vaccination by Severity [For Group 1 -Within 7 days after first doses of 9vHPV vaccine + TDV co-administered on Day 1 and within 7 days after second dose of TDV administered on Day 90; for Group 2 -Within 7 days after first dose of 9vHPV vaccine administered on Day 1]
Solicited local Adverse Events (AEs) (at injection site) will be collected by participants using diary cards within 7 days after vaccination and will include: Pain [Grade 0 (no pain), 1 (mild: no interference with daily activity), 2 (moderate: interference with daily activity with or without treatment) and 3 (severe: prevents daily activity with or without treatment)]; erythema and swelling [Grade 0 (<25 mm), 1 (25 - ≤ 50 mm), 2 (>50 - ≤ 100 mm), 3 (> 100 mm)].
- Percentage of Participants with Solicited Systemic Adverse Events (AEs) for 14 days Following Vaccination by Severity [For Group 1 -Within 14 days after first doses of 9vHPV vaccine + TDV co-administered on Day 1 and within 14 days after second dose of TDV administered on Day 90; for Group 2 -Within 14 days after first dose of 9vHPV vaccine administered on Day 1]
Solicited systemic AEs will be collected by participants using diary cards within 14 days after vaccination and will include fever, headache, asthenia, malaise and myalgia. Severity grades were: Grade 0: none, Grade 1: mild (no interference with daily activity), Grade 2: moderate (interference with daily activity with or without treatment), Grade 3: severe (prevents normal daily activity with or without treatment). Fever is defined as body temperature greater than or equal to 38°C (100.4°F).
- Percentage of Participants with any Unsolicited AEs for 28 days Following Vaccination [For Group 1 -Within 28 days after first doses of 9vHPV vaccine + TDV co-administered on Day 1 and within 28 days after second dose of TDV administered on Day 90; for Group 2 -Within 28 days after first dose of 9vHPV vaccine administered on Day 1]
An AE is defined as any untoward medical occurrence in a clinical investigation participant administered a study vaccine; it does not necessarily have to have a causal relationship with study vaccine administration.
- Percentage of Participants with Serious Adverse Events (SAEs) [From first vaccination (Day 1) through end of study (Day 360 [Month 12])]
An SAE is defined as any untoward medical occurrence or effect that results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability / incapacity, is a congenital anomaly / birth defect or is medically important which may require intervention to prevent the items listed above or may expose the participant to danger.
