NCT02135419

Brief Summary

The randomized phase of the trial compared topical or ablative treatment with active monitoring in preventing anal cancer in patients with human immunodeficiency virus (HIV) and high-grade squamous intraepithelial lesions (HSIL). Anal HSIL is tissue in the anal canal that has been damaged by infection with human papillomavirus (HPV) and is at risk for turning into anal cancer. The ANCHOR Data Safety Monitoring Board (DSMB) determined that the primary study endpoint was completed, based on the data and statistical analysis presented to them on 07SEP2021. In the post-randomization phase of this trial, all enrolled participants are offered treatment for HSIL and/or follow-up, at the participant's choice.

Study Arms (2)

Arm I (treatment)

EXPERIMENTAL

Patients are directed to receive either topical or ablative treatment at the discretion of the clinician. Patients receiving topical treatment apply imiquimod intra-anally, peri-anally or both thrice weekly for up to 16 weeks, fluorouracil twice daily for 5 days every 2 weeks for up to 16 weeks, or trichloroacetic acid every 3 weeks up to 12 weeks. Patients receiving ablative treatment using infrared photocoagulation therapy, hyfrecation/electrocautery (thermal ablation therapy), or laser therapy. Patients may undergo excision under anesthesia if the clinician believes none of the other treatment approaches will be effective. The number and timing of such treatments will be at the discretion of the investigator. Patients with persistent HSIL should continue a protocol-approved treatment or a new protocol treatment should be considered. All participants will have samples collected for laboratory biomarker analysis.

  • Women of childbearing potential must have a negative urine pregnancy test within 7 days of initiating study treatment if they have been randomized to the treatment arm; all women of childbearing potential must agree to use a reliable birth control method (oral contraceptive pills, intrauterine device, Nexplanon, DepoProvera, or permanent sterilization, etc., or another acceptable method as determined by the investigator) during the entire period of the trial (5 years or more), and must not intend to become pregnant during study participation and for 3 months after treatment is discontinued; all participants must be willing to comply with an acceptable birth control regimen as determined by the Investigator
  • Men randomized to the treatment arm should not father a baby while receiving topical treatment during this study.

  • Ability to understand and the willingness to sign a written informed consent document
  • Participant is willing to be randomized and able to comply with the protocol
  • Clinician is comfortable with either following patient for up to 5 years without therapy or treating patient for up to 5 years

You may not qualify if:

  • Inability to provide informed consent
  • Patients who are receiving any other immunomodulatory investigational agents (replacement doses of steroids for adrenal insufficiency or treatment with prednisone ≤5 mg/day is permitted) within the 4 weeks before randomization enrollment, other than investigational antiretroviral agents for HIV, or investigational or approved agents for Hepatitis C.
  • History of anal cancer, penile, vulvar, vaginal or cervical cancer, or signs of these cancers at baseline.
  • Treatment or removal of HSIL less than 6 months prior to randomization.
  • Participant has symptoms related to HSIL and would benefit more from immediate treatment than from entry into the study and potential for randomization to active monitoring arm
  • Current systemic chemotherapy or radiation therapy that potentially causes bone marrow suppression that would preclude safe treatment of HSIL
  • Participants who only have a single HSIL lesion that is likely to be removed entirely with the initial screening biopsy
  • Warts so extensive that they preclude the clinician from determining the extent and location of HSIL
  • Participant plans to relocate away from the study site to a location without an ANCHOR study site during study participation

Model Details: All participants are evaluated with high resolution anoscopy and anal cytology every 6 months during study participation. Participants randomized to treatment undergo biopsy of anal HSIL at each 6-month visit, and receive topical or ablative therapies for incident anal HSIL lesions. Active monitoring participants undergo close observation, with biopsy of anal HSIL at annual visits. Participants undergo biopsy of lesions at any time cancer is suspected.
