Résumé succinct
This is a randomized observer-blind placebo-controlled proof-of-concept study with the aim to assess the safety and tolerability, and the immunogenicity of a bivalent HPV vaccine administered in healthy infants and toddlers (9- and 15-month-olds) comparing them to an immune-bridging population of 15-20-year-old unmarried females in an open label study in Ghana at the Dodowa Health Research Center.
Description détaillée
Cervical cancer is a significant public health problem in Africa and a leading cause of cancer deaths in women. According to the WHO, Africa has the highest cervical cancer disease incidence and associated mortality in the world accounting for 19% of all global cases of cervical cancer and 23% of all cervical cancer related deaths. The high-risk Human Papillomavirus (HPV) Types16 and 18 are responsible for 70% of all...Afficher plus

Critère principal d'évaluation
Critère secondaire d'évaluation
| Critères d'évaluation | Description de la mesure | Période |
|---|---|---|
Safety and Reactogenicity of HPV Vaccination | Occurrence of solicited and unsolicited adverse events following single-dose or two-dose HPV vaccination administered concomitantly with routine Expanded Programme on Immunization (EPI) vaccines, including Measles and Rubella (MR) vaccine, among infants aged 9 months, toddlers aged 15 months, and children aged 2-5 years. Results will be summarized as the number of participants experiencing adverse events | 9 months post vaccination |
HPV16/18 VLP ELISA Antibody Titers | HPV16 and HPV18 antibody levels measured using Virus-Like Particle (VLP) Enzyme-Linked Immunosorbent Assay (ELISA) in serum samples collected from participants who received one or two doses of HPV vaccine. Antibody levels are expressed as ELISA antibody titers (IU/mL). | At 1, 7, 12, and 24 months post-HPV vaccination |
Geometric Mean Concentration of HPV16/18 Antibodies | Geometric mean concentration (GMC) of HPV16 and HPV18 antibodies measured using VLP ELISA in vaccinated participants, expressed as IU/mL. | At 1, 7, 12, and 24 months post-HPV vaccination |
| Critères d'évaluation | Description de la mesure | Période |
|---|---|---|
HPV16/18 Seroconversion Rate | Seroconversion rate of HPV16 and HPV18 antibodies measured using VLP ELISA, defined as the proportion of participants who change from seronegative at baseline to seropositive after HPV vaccination. Results are expressed as a percentage of participants | 1 month and 7 months post HPV vaccination |
HPV16/18 VLP ELISA Antibody Titers by Age and Sex | HPV16 and HPV18 antibody titers measured using VLP ELISA among male and female infants and toddlers aged 9 and 15 months and children aged 2-5 years following HPV vaccination, expressed as ELISA antibody titers (IU/mL). | At 1, 7, 12, and 24 months post-HPV vaccination |
Geometric Mean Concentration of HPV16/18 Antibodies by Age Group | Geometric mean concentration (GMC) of HPV16 and HPV18 antibodies measured using VLP ELISA among infants, toddlers, and children receiving HPV vaccination, expressed as IU/mL. | At 1, 7, 12, and 24 months post-HPV vaccination |
Measles and Rubella Seroconversion Rate | Seroconversion rate of Measles and Rubella antibodies measured one month after MR vaccination among 9- and 15-month-old infants and toddlers who received MR vaccine with or without concomitant HPV vaccination. Results are expressed as a percentage of participants. | 1 month post MR vaccination |

An individual who meets any of the following criteria will be excluded from participation in this study:
- Pregnancy, lactation, or intention to become pregnant during the vaccination phase through three months after the study vaccine dose
- Previous vaccination against HPV (Only for the 15-20-year-old efficacy cohort)
- Presence of malnutrition (weight-for-length z-score ≤-2SD median, per WHO published child growth standards)
- Planning to migrate out of the study areas before the end of the study follow-up
- Any underlying known condition or criteria, including acute or chronic clinically significant abnormality or infection that in the opinion of the investigator might compromise the wellbeing of the participant or interfere with the outcome of the study.
- Administration of immunoglobulins and/ or any blood products within the three months preceding the administration of the study vaccine.
- Known history of allergy or anaphylaxis to study vaccine components and/or excipients or other medications, or any other allergies deemed by the investigator to increase the risk of an adverse reaction.
- Any confirmed or suspected immunosuppressive or immunodeficient state, asplenia, recurrent severe infections and chronic use (more than 14 days) of immunosuppressant medication within 3 months prior to recruitment (topical steroids may be allowed).
