NCT06491446

Brief Summary

This is a blinded study to assess safety, tolerability, and efficacy of ABI-2280 vaginal inserts in participants diagnosed with persistent cervical hrHPV infection. This study will have up to 11 cohorts with various dose strengths and regimens. Each cohort will start with a sentinel cohort of 8 participants. Sentinel cohorts may be expanded to include an additional up to 32 participants to provide additional proof of concept data to further understanding of benefit/risk of a given dose/dose regimen.

Outcome Measures

Primary Outcomes (2)

  • For sentinel cohorts: Incidence and Severity of Adverse Events

    For sentinel cohorts: for each dose/dosing regimen, incidence and severity of adverse events (AEs), relationship of AEs to investigational product (IP), and AEs leading to treatment reduction/discontinuation for ABI-2280 Vaginal Insert vs. pooled placebo

    Week 24

  • For fully expanded cohorts, including sentinel: Clearance of persistent cervical hrHPV infection as defined by the absence of all hrHPV genotypes present at baseline

    Proportion of participants who received ABI-2280 vs pooled placebo who are complete responders.

    Week 12

Secondary Outcomes (2)

  • For fully expanded cohorts, including sentinel: Incidence and Severity of Adverse Events

    Week 24

  • Proportion of participants who received ABI-2280 vs pooled placebo who are complete responders
