Feasibility Study Comparing Use of One Or Two Probes for Thermal Ablation Among Screen Positive Women Living With HIV in C1001P-CS2 Kenya
A study testing Thermal ablation (TA) with 1 probe and Thermal ablation (TA) with 2 probes in people with HIV (Human Immunodeficiency Virus) and HPV, run by Fred Hutchinson Cancer Center at 1 site in Kenya.
Trial summary

About this study
Official title: Expanded Use of Thermal Ablation (EXCEL Cohort) and Prophylactic Use of Two Probes (PRO Cohort) for Cervical Cancer Prevention in Women Living With HIV
Cervical cancer disproportionately affects women in low- and middle-income countries (LMICs), particularly women living with HIV (WLWH) who have a 6-fold increased risk of cervical cancer compared to women in the general population. Thermal ablation (TA) is recommended by the World Health Organization (WHO) to treat cervical precancerous lesions, although its efficacy can be suboptimal in WLWH. In Kenya, the estimated incidence rate of cervical cancer is 31-33 per 100,000 women per year among women without HIV and approximately 70-100 per 100,000 among WLWH.
The proposed study will evaluate the feasibility, acceptability, and safety of a two-probe TA technique (endocervical and ectocervical probes) and whether this approach improves treatment outcomes among WLWH compared to one (ectocervical) probe. This innovation has the potential to significantly enhance cervical cancer prevention efforts in high-burden settings. It will also contribute towards achieving the 90-70-90 goals of the WHO strategy for accelerated elimination of cervical cancer as a public health problem by 2030.
Read the detailed description
Participants will first undergo HPV testing or visual inspection with acetic acid at screening. Participants with positive screening results undergo a clinical exam comprising visual inspection with acetic acid, digital imaging, brush biopsies of the ectocervix and the endocervix, and assessment for TA treatment. Participants who have a type 1 transformation zone (TZ1) and are otherwise eligible for TA will receive TA with either one or two probes. Screen positive women will be randomized to:
GROUP 1: TA with 1 probe. GROUP 2: TA with 2 probes.
Participants are followed up at 6 months with an HPV test, brush biopsies, and visual assessment of the cervix.
Participants who are not TA eligible will be referred to local care.

Questions about this trial
What is this clinical trial studying?
A study testing Thermal ablation (TA) with 1 probe and Thermal ablation (TA) with 2 probes in people with HIV (Human Immunodeficiency Virus) and HPV, run by Fred Hutchinson Cancer Center at 1 site in Kenya.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 8 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 20 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Kenya. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Araceli Loera, MPH (+1 206-667-5816, aloera@fredhutch.org), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
HPV positive (time frame: From enrollment to follow up at 6 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Oct 2026.
