Large Algorithm Setting and Validation Study

In this pilot study, prospectively acquired clinician-collected and participant-collected vaginal swab specimens will be obtained from up to 1000 individuals with signs and symptoms of vaginitis to develop and validate a bacterial vaginosis diagnostic algorithm and evaluate the performance of the Nanopath assay. The Nanopath assay is an amplification-free molecular test that detects pathogens associated with vaginitis. The performance of the Nanopath assay will be assessed by comparing Nanopath assay results to previously FDA-cleared commercial tests and yeast culture.

Study to Evaluate Efficacy and Safety of Gyntima® Balance in Preventing Recurrences of Bacterial Vaginosis

The vagina is a dynamic muscular organ whose health relies on a Lactobacillus-dominant microbiota that maintains low pH and protects against infections. Bacterial vaginosis (BV) is the most common vaginal imbalance in women of reproductive age, caused by depletion of protective Lactobacillus species and overgrowth of anaerobic bacteria such as Gardnerella vaginalis. BV affects an estimated 23-29 percentage of women globally (10-30 percentage in India) and is associated with discharge, odor, discomfort, and significant risks including recurrent disease, adverse reproductive outcomes, and increased susceptibility to STIs. Although antibiotics are effective for acute treatment, recurrence rates are high (50-60 percentage within 12 months), highlighting an unmet need for preventive strategies. Probiotics, particularly Lactobacillus species, have emerged as promising options to restore vaginal microbiota balance and reduce BV recurrence. Lactobacillus gasseri is a natural vaginal commensal with antimicrobial activity against BV pathogens and the ability to lower vaginal pH. L. gasseri KABP®064 has demonstrated vaginal colonization after oral administration, good tolerability, and potential to promote vaginal health. The present randomized, double-blind, placebo-controlled trial aims to evaluate the efficacy and safety of oral L. gasseri KABP®064 in preventing BV recurrence over six months following standard antibiotic therapy. Outcomes include recurrence rates and timing, symptom severity, microbiological balance, inflammation markers, and patient-reported vaginal health, supporting a microbiome-focused, non-antibiotic approach to BV recurrence prevention.

Impact of Internal Menstrual Protections on Immunity and Vaginal Microbiota

The availability, effectiveness, and safety of menstrual protection represent a key public health issue. However, research on women's menstrual and sexual health remains extremely limited. Whether societal or pathological, many hypotheses are emerging regarding the effects of menstrual protection products, yet little attention has been given to the products themselves, their societal role, or their physiological and pathological consequences. Internal menstrual products, such as tampons and menstrual cups, are widely used but are subject to limited regulatory oversight, and few studies have investigated their long-term effects on vaginal health. This study aims to investigate how different types of menstrual protection influence vaginal microbiota, immune responses, and the recurrence of gynecological conditions such as bacterial vaginosis, mycosis, or dysbiosis. Biological samples (vaginal, cervical, urinary, and blood) will be collected to analyze vaginal microbiota composition and local immunity. Participants will be divided into three groups based on their main type of menstrual protection: menstrual cup users, tampon users, and external pad users. The study will compare these groups to assess potential differences in vaginal health and immune response related to menstrual product use.
