Study Description

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.
