Detailed Description
The study will incorporate a harmonized protocol among the 8 countries to estimate point-prevalence of high-risk HPV (HR HPV) in low socio-economic populations and, among specific sub-populations, the incidence of persistent HPV infection. Due to differences in study settings, study population, targeted age-group, and eligibility criteria, country-specific protocols will be developed to complement the multi-country master protocol. In the master protocol, general principles on study design and methodology will be described, while the country-specific protocol will elaborate in more detail on methodology in each country related to subject identification, the enrolment process, and laboratory analysis. A standardized survey questionnaire, with some minor country-specific adaptations, and laboratory assays will be implemented throughout the participating countries in order to generate comparable data.
Two separate approaches will be implemented to estimate prevalence and incidence respectively in each participating country. First, cross-sectional surveys (CSS) will be conducted in both urban and rural areas of selected countries in order to estimate the point prevalence of HPV infection in sub-Saharan Africa and South Asia. The CSS will enrol girls and women aged 9-50 years, with equal sample size from four age-strata: 9-14, 15-20, 21- 30, 31-50. For specific populations, age-strata will be modified to include 12-35 years olds considering the target population characteristics and local context. Multi-stage cluster random sampling or another applicable sampling strategy will be applied to ensure representativeness. Urine samples will be collected for HPV testing, along with data on demographics, socioeconomic status, sexual and reproductive history, attitudes towards and awareness and uptake of cervical cancer screening and HPV vaccination, and potential risk factors for HPV infection and cervical cancer. Additional data will be collected on knowledge of HPV, and attitudes, uptake and use of vaccines, using standardized questionnaires and case report forms.
Second, Longitudinal studies (LS) will estimate the incidence of persistent HPV infection in sexually active girls and young women in geographically defined communities and special populations. Depending on the country setting, the LS will enroll sexually active girls and women who are aged between 15-35 years and follow them up to 24 months. Participants will be tested every 6 months for 24 months to determine incident persistent HR HPV infection. In selected countries, urine and self-collected vaginal swabs (SCVS) will be collected at the first visit to determine the comparability of HPV genotyping results from both sample types. For all the other visits, only SCVS will be collected. Data on demographics, socioeconomic status, sexual and reproductive history, cervical screening, HPV vaccination, and other potential risk factors will be collected using standardized questionnaires.
Furthermore, the qualitative sub-studies in five selected countries (Bangladesh, Nepal, Pakistan, Sierra Leone, DR Congo) will follow and draw on findings from the CSS, focusing on girls and women of different age strata as well as community members (including boys and men) and key informants in the health care system in each study site. Qualitative study methods will vary depending on the site and CSS findings, but will include both individual in- depth interviews (IDIs) (up to ~ 30 individuals per site), key informant interviews as well as multiple focus group discussions (FGDs) with ~6-8 participants/group. Detailed qualitative study methodology will be developed separately as another study protocol and adapted according to the procedures for each site.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
To estimate the prevalence (single time point detection) of HPV 16 and/or 18 infection among a representative sample of girls and women aged 9-50y in a range of settings.
Time Frame: Q4 2023 to Q4 2024
|
HPV 16 and 18 are the most common types associated with an increased risk of cervical, anal, and other types of cancer.
The incidence of HPV infection rises quickly after sexual debut and HPV infection is most common among young adults up to the age of 30, with incidence generally declining after that.
The proposed age range of 9-50 years old for the CSS has been divided into four age-strata, 9-14, 15-20, 21-30, 31-50 years old, in order to understand the HPV prevalence among the age group targeted for primary series of HPV vaccine (9-14 years old), the age group targeted for multi-age cohort catch-up campaign (15-20 years old) and to gather prevalence data on older females.
|
Q4 2023 to Q4 2024
|
To estimate the incidence of ≥6-month persistent HPV 16 and/or 18 infection (defined as two sequential type-specific positives with an interval of 6 months) in selected populations over 2 years.
Time Frame: Q4 2023 to Q4 2026
|
The age range for the LS will target the age group that is anticipated to have the highest incidence (e.g.
newly sexually active girls and women) or to meet the specific research needs.
The progression of HPV infection can lead to the development of premalignant lesions in the epithelial lining, ranging from low-grade (CIN 1) to high-grade (CIN 2 and 3).
Persistent infection with high-risk HPV genotypes can result in premalignant and malignant lesions which typically take over 10-20 years to develop.
An endpoint of 6-month persistent HPV infection has been commonly used in both epidemiological studies of HPV infection and clinical trials of HPV vaccines.

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
To estimate the prevalence of high risk (HR) HPV infection among a representative sample of girls and women aged 9-50 years in a range of settings, and to evaluate potential risk factors for HPV infection.
Time Frame: Q4 2023 to Q4 2024
|
This study aims to provide standard data among girls and women ages 9-50 in 8 countries, 3 in South Asia, and 5 in Sub-Saharan Africa, on the burden of HPV in a representative population sample of lower socio-economic status, as well as in particular vulnerable sub-populations of girls and women depending on the country.
|
Q4 2023 to Q4 2024
|
To estimate the incidence of ≥6-month persistent HR HPV infection in selected populations over 2 years.
Time Frame: Q4 2023 to Q4 2026
|
Countries have been selected such that there will be representation from countries with high, medium, or low HIV incidence, high and low cervical cancer incidence, those with or without HPV screening and treatment programs, and countries that are in various stages of prophylactic HPV vaccine rollout.
|
Q4 2023 to Q4 2026
|
Descriptive statistics of the knowledge, attitudes, and beliefs regarding HPV vaccination, cervical cancer screening and treatment.
Time Frame: Q1 2024 to Q4 2025
|
For each CSS and LS, study data will be summarized using descriptive statistics (mean, standard deviation, median, minimum, and maximum) for continuous variables, and counts and percentages for categorical variables.
The denominator for each percentage will be the number of participants who were eligible for each CSS/LS unless otherwise specified.
|
Q1 2024 to Q4 2025
|
Descriptive statistics of the perceptions of gender norms and stigma, and gender-related dynamics that may influence HPV burden and/or create barriers that influence girls/women's access to and uptake of HPV prevention, screening, and treatment services
Time Frame: Q1 2024 to Q4 2025
|
For each CSS and LS, study data will be summarized using descriptive statistics (mean, standard deviation, median, minimum, and maximum) for continuous variables, and counts and percentages for categorical variables.
The denominator for each percentage will be the number of participants who were eligible for each CSS/LS unless otherwise specified.
|
Q1 2024 to Q4 2025
|
Sensitivity, specificity, Accuracy, ROC, Cohen's kappa coefficient of HPV genotyping results obtained from urine and self-collected vaginal swabs (SCVS).
Time Frame: Q1 2024 to Q4 2024
|
In LS, participants will be tested every 6 months for 24 months to determine incident persistent HR HPV infection.
In selected countries, urine and self-collected vaginal swabs (SCVS) will be collected at the first visit to determine the comparability of HPV genotyping results from both sample types.
For all the other visits, only SCVS will be collected.
