Trial Summary

What is the purpose of this trial?This trial tests whether adding beneficial bacteria called L. crispatus to the vagina can help women with bacterial vaginosis who are taking antibiotics. The goal is to see if these good bacteria can safely and effectively establish themselves in the vagina and maintain a healthy balance. Lactobacillus crispatus has been studied in various clinical trials for its potential to prevent bacterial vaginosis recurrence and restore normal vaginal flora.

Eligibility Criteria

This trial is for premenopausal individuals aged 18-40 with bacterial vaginosis, as confirmed by specific criteria. They must be willing to follow the study procedures, not pregnant or breastfeeding, HIV negative, and on certain contraceptives. Exclusions include significant reproductive tract diseases, recent antibiotic use or infections other than BV, certain medication use within the last month, and any condition that may affect participation.

I am a premenopausal person aged between 18 and 40.

Treatment Details

The trial tests two vaginal live biotherapeutic products (LBPs) containing different strains of L. crispatus (LC106 & LC115) against a placebo in people treated with antibiotics for BV. It aims to see if these LBPs are safe and can colonize the vagina post-treatment.
