The Prevent Anal Cancer Self-Swab Study

October 17, 2024 updated by: Alan Nyitray, PhD, Medical College of Wisconsin

Annual Anal Sampling Using DNA Screening to Identify Men Who Have Sex With Men at Increased Risk for Anal Cancer

The purpose of this research study is to find ways to screen for anal cancer among gay, bisexual, and other men who have sex with men (MSM) and transgender persons. This study will try to find out if persons will do annual anal cancer screening, what factors are associated with repeated screening, and how this affects a person's decision to have high-resolution anoscopy.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a prospective, randomized, two-arm clinical study to evaluate compliance with annual home-based vs clinic-based DNA screening of anal canal exfoliated cells among Milwaukee HIV+ and HIV- men who have sex with men (MSM) and transgender persons aged ≥25 years. At study entry, persons randomized to arm 1 will receive a home-based collection kit in the mail at 0 and 12 months and those in arm 2 will attend a clinic where a clinician will collect the exfoliated cell specimen at 0 and 12 months. Then, persons will receive high-resolution anoscopy (HRA)-directed biopsy to assess precancerous lesions by study arm. We hypothesize that a majority of persons will comply with annual screening with increased compliance among persons in the home-based arm vs clinic-based arm. The proposed research could indicate that annual HPV DNA screening and subsequent HRA are acceptable to MSM and transgender persons; thus, we will determine how high-risk persons are identified for HRA in light of limited HRA resources. The duration of each participant's activities is expected to be 12 months. The study is expected have participant activity from 2019 to 2023.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Compliance With Annual Anal HPV DNA Screening

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Human Papillomavirus (HPV) DNA Persistence and Its Association With High-grade Squamous Intraepithelial Lesions (HSIL).
Time Frame: 12 months
The number of participants that have DNA persistence at 12 months with and without high-grade squamous intraepithelial lesions (HSIL).
12 months
Host/Viral Methylation and Its Association With High-grade Squamous Intraepithelial Lesions.
Time Frame: 12 months
Mean of host/viral methylation score among participants stratified by high-grade squamous intraepithelial lesions. The Score 5 (S5) methylation score is an arithmetic continuous risk score with a minimum value of 0 and no maximum value. Higher methylation scores indicate higher risk for disease. While a theoretical maximum for a methylation score does not exist, one published maximum value for anal cancer is approximately 100. In this publication (Lorincz et al., Methylation of HPV and a tumor suppressor gene reveals anal cancer and precursor lesions, DOI: 10.18632/oncotarget.17984), a cut-off of 7.5 for methylation score identified all anal cancers and HSIL.
