Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a randomized, double-blind, placebo-controlled Phase 1b/2 study in women diagnosed with persistent cervical hrHPV infection. This study is designed to assess safety, tolerability, and efficacy following the use of ABI-2280 Vaginal Insert delivered intravaginally. Sentinel cohorts will be utilized to assess tolerable regimens, which may trigger cohort expansions if some evidence of efficacy is observed.

Dose range and dosing regimens in this study will be evaluated through the enrollment of up to 11 sentinel cohorts, each enrolling up to 8 participants.
