Study on the Efficacy of Crispact® (Probiotic Containing Lactobacillus Crispatus M247) in the Sterilization of HPV-HR and in the Reconstitution of the Normal Vaginal Microbiota

There is growing scientific interest in probiotic supplementation as a possible therapy for clearing the human papillomavirus (HPV) infection and reducing the risk of developement of cervical cancer.

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

This is a multicenter, randomized, longitudinal, prospective, parallel-group, single-blind study aimed to investigate the efficacy of probiotic Crispact® (which contains: 20 Bld CFU/Stick of Lactobacillus crispatus M247) in clearance of human papillomavirus (HPV) infection in healthy female who tested positive for human papillomavirus (HPV) infection.

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

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Women able to understand and agree to participation in the study and be able to provide written informed consent to the trial.
  • Women aged 25-29 years who perform screening pap smears with the result: Low- grade squamous intraepithelial lesion (LSIL) or Atypical Squamous Cells of Undetermined Significanc (ASCUS) (for which, as per the recommendation of the Italian Society of Colposcopy and Cervico-Vaginal Pathology (SICPCV)/Italian Group of Cervical Cancer. Screening (GISCI), no treatment is indicated but only follow-up with Human papillomavirus (HPV) test at 12 months.
  • Women aged 18-64 who independently perform a positive High risk sub-types of HPV (HR-HPV) test outside of screening even in the presence of a negative cytology (for whom, as per the recommendation of the SICPCV, no treatment is indicated but only follow-up with HPV test at 12 months).
  • Women aged 30-64 years HPV HR positive with negative cytology or with positive cytology for ASCUS or LSIL but negative colposcopy (absence of colposcopic lesion or positive colposcopy but subsequent negative biopsy) who do not require treatment (therefore as per the recommendation of the SICPCV go to follow-up with HPV testing at 12 months).

Exclusion Criteria:

  • Women who have been vaccinated for HPV.
  • Patients who have undergone cervical treatments for preneoplastic pathology.
  • Patients with High-Grade Squamous Intraepithelial Lesion (HSIL) cytological result who on histological examination after biopsy need treatment according to the SICPCV 2019 recommendations.
  • Hypersensitivity to one or more components of the product.
  • Patients being treated with antibiotic, immunomodulatory and immunosuppressive therapies.
  • Patients with immune system or neoplastic pathologies being treated with chemotherapy
  • Patients who are pregnant, breastfeeding, or planning to become pregnant in the next 6 months.
