Uterine Cervical Dysplasia

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

The goal of the COMBISCREEN project is to develop a fully molecular cervical screening and triage approach that is applicable on self-samples, which are an easily accessible and non-invasive source of biomarkers. The project allows a one-step screening and triage modality and thereby identifies women with clinically relevant disease that are in need of treatment.

Conservative management of high-grade squamous intraepithelial lesions (HSILs) seems safe and justified in young women (\<30 years), but evidence is insufficient on whether it is also advisable for older women. This study will be conducted to analyze spontaneous HSIL regression rates in women of reproductive age and establish whether conservative HSIL management could be safely recommended to women of childbearing potential, irrespective of age. This is a single-center prospective observational study that will include consecutive women of reproductive age, referred to a tertiary hospital due to HSIL between March 2021 and December 2025, who prefer conservative management rather than immediate cervical conization. All patients will be followed-up regularly with colposcopy, cytology, human papillomavirus (HPV) testing and biopsies. In case their lesions progress or HSIL persists after 24 months of follow-up, conization will be indicated. Rates of spontaneous regression or resolution, as well as progression rates, will be assessed. Furthermore, the association between potential predictive factors and HSIL resolution will be analyzed.
