High-risk HPV (Any Strain)

The goal of this clinical trial is to learn if an investigational vaginal suppository therapy works to treat low-grade cervical lesions (ASC-US and LSIL) associated with high-risk human papillomavirus (hr-HPV) infection in women. It will also learn about the safety and tolerability of this investigational therapy. The main questions it aims to answer are: * Does the investigational therapy lead to regression of cervical lesions? * Does the investigational therapy help clear hr-HPV infection? * Do any adverse effects occur from using this medical product? Researchers will compare the investigational therapy to a placebo (a look-alike substance that contains no active drug) to see if the investigational therapy works. Participants will: * Be screened for hr-HPV, cervical abnormalities, and other conditions to be assessed for eligibility * Self-administer 15 doses of the investigational therapy or placebo as a vaginal suppository over 19 calendar days * Attend scheduled clinic visits for examinations, testing, and monitoring for a period of two months * Undergo assessments to evaluate cervical lesion status, hr-HPV infection, and safety outcomes * Keep a daily diary of investigational therapy use and associated information

This is a randomized, open-label trial, to assess whether a single dose of HPV nonavalent vaccine, administered to HIV uninfected, unvaccinated women with high risk HPV16/18/31/33/45/52 or 58 can decrease the infectivity of shed HPV viruses. Our hypothesis is that vaccination will have little or no impact on HPV sample positivity by DNA PCR since the viral particles will continue to be produced and released, but that particles will be neutralized by vaccine-induced antibodies, thereby reducing their infective capacity. Cervical samples will be collected at randomisation and at 6 months, to compare infectivity of shed HPV viruses.
