Effect of EGCG, Folic Acid, Vitamin B12 and Hyaluronic Acid on HPV DNA Integration

Starting soon · Not applicable

Conditions studied: HPV Infection, HPV Integration, HPV Disease, HPV Genital Infection, HPV Persistence, Low Grade Squamous Intraepithelial Lesions of the Cervix

In brief

This interventional, single-center, open-label randomized clinical study evaluates the efficacy of an oral dietary supplement (Pervistop®) in women with persistent Human Papillomavirus (HPV) infection. The supplement is a combination of four natural molecules: Epigallocatechin gallate (EGCG), folic acid (FA), vitamin B12 (B12), and hyaluronic acid (HA).The primary objective is to describe the effect of this association on HPV DNA integration into the host genome by measuring the clearance rate of viral oncoproteins E6 and E7. A total of 42 women aged 25 or older with persistent HPV infection and low-grade cervical lesions will be randomized 1:1 into two groups. The treated group will receive one tablet of Pervistop® daily for six months, while the control group will follow standard clinical practice. The study aims to determine if this nutritional intervention can counteract viral persistence.

Who can join

Age: 25 and older. Sex: female. Healthy volunteers: not accepted.

You may qualify if…

• Age ≥ 25 years old
• Positive HPV DNA test with genotyping 9-24 months prior to Day 0
• Positive HPV DNA test with genotyping at Day 0
• Presence of an HPV-related cervical lesion within 5-24 months prior to Day 0. This lesion will be defined alternatively as:
• Pap test: LSIL, ASC-US.
• Colposcopic impression suggestive of a low-grade lesion.
