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

July 6, 2026 updated by: Massimo Origoni, IRCCS San Raffaele

An Interventional Study Evaluating the Effect of Epigallocatechin Gallate (EGCG), Folic Acid (FA), Vitamin B12 (B12) and Hyaluronic Acid (HA) in Affecting the DNA Integration of Human Papilloma Virus (HPV) in Women With Persistent Infection

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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Human Papillomavirus (HPV) is a common sexually transmitted infection that, while often regressing spontaneously, can persist. Persistent high-risk HPV infection is a major risk factor for cervical cancer because it allows viral DNA to integrate into the host genome. This integration triggers the constitutive expression of viral oncoproteins E6 and E7, which block the host's tumor suppressor genes (p53 and prb), leading to uncontrolled cell proliferation.Currently, clinical practice for low-grade lesions typically involves a surveillance approach. This study explores the use of a synergic combination of EGCG (anti-proliferative/pro-apoptotic), Vitamin B12 and Folic Acid (methylation agents), and Hyaluronic Acid (epithelial integrity) to promote viral clearance and inhibit E6/E7 expression.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Inclusion Criteria:

  1. Age ≥ 25 years old
  2. Positive HPV DNA test with genotyping 9-24 months prior to Day 0

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Rate of clearance of viral oncoproteins E6 and E7
Time Frame: 6 months
The percentage of participants showing a negative result for viral E6/E7 mRNA, which are key indicators of HPV DNA integration into the host genome. Analysis will be performed using the Aptima HPV assay, a transcription-mediated amplification (TMA) technique. A negative test result indicates viral clearance or loss of viral integration.
6 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
HPV DNA Clearance Rate
Time Frame: 6 months
The rate of participants who test negative for high-risk HPV DNA using a multiplex PCR kit (Allplex II HPV 28 Detection). A negative result is defined as the absence of detectable high-risk HPV DNA above the analytical limit of detection
6 months
Treatment Adherence score
Time Frame: 6 months
Adherence to the oral supplementation protocol evaluated through the Morisky Medication Adherence Scale (MMAS-4) questionnaire
6 months

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Quantitative Variation of E6/E7 Levels from baseline to T1
Time Frame: 6 months
Variation of E6/E7 mRNA levels. Exploratory analysis of quantitative signals generated by the Aptima assay in the form of Relative Luminescent Units (RLU). The RLU value directly corresponds to the amount of target E6/E7 mRNA detected in the sample.
