Clinical Trial Summary

clinical trial comparing the regression rate after 12 months of histologically confirmed cervical intraepithelial lesions 1 in 2 parallel groups. One group using the vaginal gel Papilocare® for 6 months and one group without any treatment.

Description:

Cervical cancer affects 3000 women and causes 1100 deaths every year in France. This type of cancer usually takes about 10 to 15 years to develop and has distinct precursor stages. Persistent infection by Human Papillomavirus is necessary for the development of these lesions.

Currently, when a colposcopy biopsy reveals low grade lesion, it is recommanded to make a new cervical cytology or HPV testing, 12 months later. No treatment is recommended over this period. However 11% of these lesions evolve from low to high grade.

Papilocare® is a vaginal gel that would improve the re-epithelialization of the uterine cervix. Creating a protective film on the cervix, it could induce a favorable environment for regression of the cervical intraepithelial lesions 1 and for clearance of Human Papillomavirus.

The goal of our study is to include 150 women with a histologically confirmed cervical intraepithelial lesions 1. Half of them will be using the vaginal gel Papilocare® for 6 month while the other half will not receive any treatment (as suggested by current recommendations). Each patient will have a cervical cytology and a HPV testing after 6 months and after 12 months. Therefore we will be able to compare the percentage of normalization of cervical cytology and HPV clearance for each group after 6 months and after 12 months.

Patients will visit the Orleans hospital once for the inclusion and twice for follow-ups after 6 months and 12 months.

If the use of Papilocare® really induces a significant regression of low grade lesions, this vaginal gel could be offered as soon as these lesions are histologically identified in order to stop its progress to high grade.

Recruitment information / eligibility

• Status: Completed
• Enrollment: 81
• Est. completion date: May 17, 2023
• Est. primary completion date: May 17, 2023
• Accepts healthy volunteers: No
• Gender: Female
• Age group: 25 Years and older

Eligibility

Inclusion Criteria:

• Women aged 25 years old or older.

• With histologically-confirmed cervical intraepithelial lesion 1 only, proven by colposcopy biopsy, done in the most suspiscious area.

• With complete colposcopy, performed less than 3 months prior the inclusion

• With confirmed ASC-US or LSIL cervical-cytology, performed less than 6 months prior the colposcopy.

Exclusion Criteria:

• Women under guardianship or curatorship

• Women under the protection of justice

• Women not affiliated with a social security system

• Pregnant woman (as vaginal gel has not been evaluated in pregnant women) Urinary dosing of BHCG will be performed on the day of inclusion for all women under 55 years of age and effective contraception is recommended during the study for all non-menopausal women.

• Immunodepressed women (HIV, immunosuppressive treatments ...)

• Woman using vaginal contraceptives (ring, spermicides, cervical cap; because of risk of interaction) NB: Papilocare is compatible with the use of condoms and intrauterine devices.

• Known allergy to one of the components

• Patients with low-grade histology with HSIL - ASC-H - AGC smear will not be included. The cyto-colposcopic discordance suggests a high-grade lesion that would not have been biopsied at colposcopy.

• Patients undergoing laser or conization treatment according to the recommendations of INCa 2016 will not be included; namely: persistence of CIN 1 for more than 24 months on at least 2 different colposcopies; high-grade squamous intraepithelial histological lesions; adenocarcinoma in situ.

• Participation in another interventional study

Intervention

Device:
• PAPILOCARE
Papilocare® is a self-administered vaginal gel. Its single-dose cannula contains hyaluronic acid and pre-biotics (Coriolus Versicolor) that would improve the re-epithelialization of the uterin cervix. By creating a protective film on the cervix, this gel could induce a favorable environment for regression of the cervical intraepithelial lesions 1 and for clearance of Human Papillomavirus. The specific approach related to our study would be to apply Papilocare® vaginal gel for 6 months for the treated group. Smear and HPV test will be perform by all patients at 6 and 12 months.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Cervical cytology normalization after 12 months.	Compare the normalization rate of the cervical cytology in each arm after 12 months.; The difference will be considered statistically significant if the treatment group has a normalization rate of 25% or higher.; An "unsatisfactory" smear in its realization will have to be repeated within 45 days.	Month 12
Secondary	Cervical cytology normalization after 6 months.	Compare the normalization rate of the cervical cytology in each arm after 6 months.	Month 6
Secondary	HPV clearance after 6 months	2) Compare in each arm the rate of transition from a positive HPV testing at inclusion to a negative HPV testing after 6 months.; The difference will be considered statistically significant if the treatment group has a clearance rate of 25% or higher.	Month 6
Secondary	HPV clearance after 12 months	2) Compare in each arm the rate of transition from a positive HPV testing at inclusion to a negative HPV testing after 12 months.; The difference will be considered statistically significant if the treatment group has a clearance rate of 25% or higher.	Month 12
Secondary	Evaluation of tolerance of Papilocare vaginal gel	Compare in each group the number of episodes of vaginal discomfort over the first 6 months.	Month 6
