Study summary

This randomized, placebo-controlled trial will evaluate self-administered 5-fluorouracil (5FU) to improve human papillomavirus (HPV) clearance after thermal ablation (TA) in Women With Human Immunodeficiency Virus (HIV) (WWH) in Kenya. The trial will also assess the safety, adherence, and acceptability of 5FU. Starting four weeks after TA, participants will self-administer 5FU cream or matched placebo intravaginally once every other week for 12 applications, with clinic visits at weeks 2, 8, 16, 24, and 48 for evaluation. All participants will be followed up to 48 weeks.

It is hypothesized that, compared to placebo, 5FU will increase HPV clearance at 24 weeks and that the proposed dosing schedule will be safe, well-tolerated, and acceptable in this population. Together with data from other studies, this trial will provide evidence on the use of self-administered intravaginal 5FU to improve HPV treatment outcomes in WWH in low- and middle-income countries, where the burden of cervical cancer is highest.

Read the detailed description

WWH face up to six times higher risk of cervical cancer, a leading cause of death in this population. Cervical cancer is caused by persistent HPV infection, which can lead to cervical intraepithelial neoplasia grade 2/3 (CIN2/3), also called cervical precancer. If untreated, CIN2/3 can progress to cervical cancer. Thermal ablation (TA) is the most commonly used treatment for HPV/precancer in low- and middle-income countries, including Kenya. However, among WWH, TA has suboptimal efficacy, with only 44-66% clearing HPV or CIN2/3 at 6-12 months, compared to 83-95% in women without HIV. This highlights the need for adjuvant therapies to improve outcomes.

Studies in high-income countries suggest that off-label, self-administered intravaginal 5FU cream can improve HPV and CIN2/3 treatment outcomes in both HIV-negative and HIV-positive women. This trial will evaluate its potential as an adjuvant therapy following TA in WWH.

Eligibility criteria

Inclusion Criteria

  • Women aged 25 years or older
  • Known -positive status
  • On antiretroviral therapy (ART) for at least 60 days prior to enrollment
  • Positive HPV screening test screening result
  • Able to provide in English, Swahili, or Dholuo
  • Agree to use dual during dosing phase if of
  • Planning to remain in study locale for duration of study (48 weeks) Exclusion Criteria
  • Current pregnancy or breastfeeding
  • History of anogenital cancer (cervical, vulvar, or anal)
  • Current use of medications
  • History of total hysterectomy
  • Known allergy to 5FU
  • Medical comorbidity that would interfere with study participation
  • Unwilling or unable to use contraception during study participation
Terms in these criteria, in plain language(5)

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.

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.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

What researchers measure

Primary outcomes

  1. High-risk human papillomavirus (hrHPV) Clearance among WWH randomized to adjuvant self-administered 5FU cream versus placebo cream following Thermal ablation (TA)

    Vaginal samples will be collected at baseline and approximately every four weeks. Clearance of hrHPV genotypes will be assessed using Polymerase Chain Reaction (PCR)-based human papillomavirus (HPV) Deoxyribonucleic Acid (DNA) testing on these follow-up samples.

    Time frame: Up to 24 weeks

Secondary outcomes

  1. Adverse Event per National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) v5.0

    Type, frequency, severity and duration of adverse events (AEs) using NCI CTCAE v5.0 will be reported. The NCI Common Terminology Criteria for Adverse Events is a descriptive terminology which can be utilized for Adverse Event (AE) reporting. A grading (severity) scale is provided for each AE term. Grade 1 Mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated. Grade 2 Moderate; minimal, local or noninvasive intervention indicated; limiting age-appropriate instrumental Activities of Daily Living (ADL). Grade 3 Severe or medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling; limiting self-care ADL. Grade 4 Life-threatening consequences; urgent intervention indicated. Grade 5 Death related to AE.

    Time frame: 24 weeks

  2. Adverse Event per National Institute of Health (NIH) Division of Acquired Immunodeficiency Syndrome (AIDS) Adverse Event Grading Criteria (DAIDS)

    Type, frequency, severity and duration of adverse events (AEs) using per DAIDS standardized scales will be reported. The DAIDS grading table provides an AE severity grading scale ranging from grades 1 to 5 with descriptions for each AE based on the following general guidelines: Grade 1 indicates a mild event, Grade 2 indicates a moderate event, Grade 3 indicates a severe event, Grade 4 indicates a potentially life-threatening event, Grade 5 indicates death.

    Time frame: Up to 24 weeks

  3. Number of successful self-administration of the intravaginal cream by participants

    Number of confirmed successful self-administrations of intravaginal 5FU or placebo cream by participants.

    Time frame: Up to 24 weeks

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Sep 2026; primary completion for Sep 2027, 12 months later.

Of 65 non-industry phase 2 interventional studies under HIV Infections, half reached primary completion within 37 months of starting (the median), counting those still running; a quarter within 24 and three quarters within 74. This study's planned 12 months is below that.

Counting every sponsor, half of 99 studies reached it within 31 months; a quarter within 17 and three quarters within 58.

How these figures are worked out, and which studies are left out of them.

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 Aug 27, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
