Study population

Women will be recruited from an existing cohort.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Female, or transgender female with a cervix, aged 18-35 years old
  • -positive
  • Stable on antiretroviral regimen containing TDF for at least 2 weeks at time of enrollment.
  • Virally suppressed (HIV-RNA copies \<50 copies/mL) for at least 6 months at time of enrollment.
  • Willing to refrain from vaginal intercourse and use of vaginal devices such as douches and sex toys within 72 hours of the visit.
  • Willing and able to give signed .

Exclusion criteria

Exclusion Criteria:

  • Currently pregnant or previous pregnancy within 3 months of enrollment
  • Currently breast feeding
  • Symptomatic vaginal infection within 2 weeks prior to enrollment
  • Unexplained, undiagnosed abnormal bleeding per vagina, bleeding per vagina during or following vaginal intercourse, or gynecologic surgery within 90 days prior to enrollment
  • History of vulvar/vaginal/ cervical dysplasia, neoplasia or cancer, atypical squamous cells of undetermined significance, condyloma, or human papilloma virus (HPV) in the past year
  • Use of oral and/or vaginal preparations of antibiotic or antifungal medications within 30 days prior to the enrollment visit
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Biopsy and archival tissue

A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.

Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. Cervical Tissue Concentrations

    Assess the influence of hormonal contraception on tenofovir concentrations in cervical tissues

    Time frame: Day 1

Secondary outcomes

  1. Proinflammatory cytokines

    To determine relationship between local inflammation and drug disposition in the female genital tract

    Time frame: Day 1

  2. Gene expression of drug metabolizing enzymes and transporters

    To assess the influence of hormonal contraception on the expression of drug metabolizing enzymes and transporters in cervical tissue

    Time frame: Day 1

  3. Vaginal microbiome

    To identify potential role of the vaginal microbiome in local drug disposition

    Time frame: Day 1

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 1, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
