About this study

Official title: European HIV&STI Prevention Network Study

The University Hospital Essen is sponsoring the Multicenter human immunodeficiency virus (HIV) and sexually transmitted infections Prevention Network Study (STIPnet) which is funded by Janssen, Pharmaceutical Companies of Johnson \& Johnson.

STIPnet study is a prospective observational cohort study aiming to determine the incidence and point prevalence of HIV infection and the most common sexually transmitted infections (STIs) in individuals with sexual risk behavior. In addition, the University Hospital Essen will examine whether individuals at risk for HIV and STI infections would retain in such a study (retention rate) and would be willing to participate in potential HIV and STI prevention trials (willingness to participate).

Read the detailed description

To develop and test novel prevention methods or interventions against sexually transmitted infections (STIs), knowledge is required on whether there are increased rates of transmission in a given population. In order for trials testing new prevention methods to be feasible and affordable, the goal is to define a group at risk where there will be at least an annual 3% incidence of new infections of the respective STI. The group definitions will be based on factors such as gender, age, sexual behavior, economic status and others. However, defining such groups is labor-intensive and costly and often not do-able for vaccine developers and developers of novel prevention/diagnostic methods. Thus, as identification and testing of the most at-risk groups to study these medicinal products is too costly, only a limited number of novel prevention methods are brought into clinical trials. Here the investigators plan to define factors such as behavioral or co-infections associated with individual STIs for potential future prevention trials. Given the increased susceptibility of human immunodeficiency (HIV) infection with STI infections, early diagnosis and treatment of STI is substantial to reduce risk factor of HIV acquisition and to inform individuals about their risk of becoming HIV infected. As STIs are a crucial factor in the scope of an incidence analysis of HIV in men who have sex with men (MSM) and are often underdiagnosed, extensive screening measures are implemented within this study.

Thus, the STIPnet study is building up a platform for effective recruitment, retention and assess important epidemiological patterns and thus, designed as a vaccine preparedness study, to gather information on the most common STIs and prepare sites for potential future vaccine trials. Indeed, several potential HIV\&STI vaccines are currently in development.

At-risk volunteers are screened every three months for HIV and other STIs, thereby establishing disease prevalence and incidence in communities that might someday support future vaccine trials. Behavioural data are also collected and participants complete a questionnaire that assesses the willingness to participate in future vaccine studies.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Determine the Incidence and Point PrevalenceBehavioural

    Determine the Incidence and Point Prevalence of human immunodeficiency virus (HIV) Infection and the Most Common Sexually Transmitted Infections in Individuals With Sexual Risk Behavior.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Choice of a cohort of volunteers at-risk for HIV and other STIs

    Participants will receive questionnaires. The group definitions will be based on factors such as gender, age, education, sexual behavior, economic status, pre- and post-exposure prophylaxis and others. Descriptive statistics will be generate to choose a cohort of volunteers at-risk for HIV and other STIs.

    Measured: Through study completion, an average of 2 years

  2. Relationship between STIs and certain behavior and risk of HIV infection

    Participants will receive a questionnaire about behavior and risk of HIV infection. Descriptive statistics will be generate to summarize the relationship between STIs and HIV infection.

    Measured: Through study completion, an average of 2 years

  3. Incidence of HIV and other STIs in a cohort of individuals at risk for HIV and other STI infections

    Descriptive statistics will be generated to summarize incidence (as measured as new HIV and STI infections occurring during the study period) HIV and STI infections. The power calculation targets a 3% incidence rate per year.

    Measured: Through study completion, an average of 2 years

Secondary outcomes (6)
  1. Prevalence of HIV and other STIs in a cohort of individuals at risk for HIV and other STI infections

    Descriptive statistics will be generated to summarize prevalence (as measured as HIV and STIs positive cases during screening visit) HIV and STI infections. Baseline HIV and STI prevalence will be defined as the number of HIV or STI infected individuals identified at screening divided by the total number of individuals who are screened for HIV or STI.

    Once enrollment is completed, baseline HIV or STI prevalence will be calculated.

    Measured: At screening (until last participant is included), an average of 1 year

  2. Co-occurence of STIs and HIV

    Analysis of laboratory and other testing results. Descriptive statistics will be generated to evaluate co-occurence of STIs and HIV.

    Measured: Through study completion, an average of 2 years

  3. Retention rates for prospective prevention studies for individuals at risk for HIV and STI infections.

    The primary assessment of retention will be conducted assuming a binomial distribution and individuals will be considered retained at 12 months if they complete the final study visit. Retention will also be estimated with 95% CI for each study visit. A summary of participant attendance and loss to follow-up will be made every 3 months to monitor the retention rate by site, and to help ensure that the overall 12-month retention rate of the study visit will be no less than 85%.

    Measured: Through study completion, an average of 2 years

  4. Willingness to participate in future clinical trials, such as those of candidate vaccines through questionnaire

    Willingness to participate in vaccine trials will be estimated assuming a binomial distribution. Factors associated with willingness to participate in vaccine trial will be evaluated using logistic regression models

    Measured: At enrollment (day 0, can be same day as screening day) and at visit 4 (visit 4 is day 364)

  5. Attitudes regarding HIV and STI prevention methods

    Attitudes regarding PrEP will be evaluated using descriptive statistics and questionnaires. Behavioral questionnaire over time will be assessed by frequency tables and bar graphs.

    Measured: At screening, at visit 1, 2, 3, 4 (visit 1 is day 84, visit 2 is day 168, visit 3 is day 252 and visit 4 is day 364)

  6. Incidence between individuals at risk for HIV and STI infections across sites and countries

    Descriptive statistics will be generated to summarize incidence (as measured as new HIV and sexual transmitted infections occurring during the study period) HIV and STI infections. Data may be compared across sites for comparison and evaluation of factors impacting incidence.

    Measured: Through study completion, an average of 2 years

Individual data sharing
Yes: The study collaborators recognize the importance of disseminating scientific and medical study data as soon as the study data sets are complete and analysed; therefore, the study leadership would encourage their presentation, discussion and publication at seminars or conferences (national, regional and international) and in reputable scientific journals in open access. All publications resulting from this study will be cleared through the collaborating partners to the study. Anonymous data can be obtained upon request to the PI of the study.Confidentiality of participants will be maintained by the fact that no individual results will be reported or published, only group/aggregate results. Data collected during the trials that underlie the results presented in scientific publications will be shared. Distribution of study data must be always approved by the scientific steering committee of the study and final approval needs to be obtained by the PI.
