NCT05659745

Brief Summary

The goal of this clinical trial is to assess the impact of a personal care product on vaginal health in a healthy participant population. The personal care product, VM-02, contains a prebiotic, postbiotic, and three distinct strains of Lactobacillus crispatus, a microbe commonly found in healthy females, together accounting for greater than 85% of known genes in this species. The intervention will be compared to a placebo intervention and will aim to assess the following in a healthy female population: Measure changes in the relative and absolute abundance of a bacterial species, Lactobacillus crispatus, in the vagina, compared the baseline (prior to use of the personal care product) to two time points after use. Observe changes in vaginal pH and self-reported discomfort from vaginal odor, compared the baseline to two time points after use. Determine the user experience of three variations of a personal care product administered in different formats to improve vaginal health and establish tolerability and user acceptability. Participants will use the personal care product according to a specific program as directed, conduct vaginal swab sampling, and answer questionnaires, each at eight time points.

Outcome Measures

Primary Outcomes (1)

  • Safety and tolerability of VM-02 at 5 x 10^8 CFU/dose based on frequency and absolute number of patient reported adverse events

    Throughout intervention and subsequent 4 week period following last dose

Secondary Outcomes (1)

  • Vaginal colonization calculated by detection of each of 3 distinct Lactobacillus crispatus strains after administration of VM-02 at 5 x 10^8 CFU/dose using metagenomic sequencing and/or strain-specific PCR-based assays

    2 and 4 weeks after intervention

Other Outcomes (3)

  • Self-reported pH values after administration of VM-02 at 5 x 10^8 CFU/dose

    2 and 4 weeks after intervention

  • Cytokine panel assays after administration of VM-02 at 5 x 10^8 CFU/dose

    2 and 4 weeks after intervention

  • Participant self-reported questionnaire outcomes after administration of VM-02 at 5 x 10^8 CFU/dose

    2 and 4 weeks after intervention

Masking Details
Due to this study being double-blind, participants will not know if they are in the condition with the test product or the placebo. Neither the test products nor the placebo used during the study will be labeled in any way that will indicate whether participants are taking the placebo or the test product. Participants will just know there is a chance they were randomized into a placebo or test product arm of the study. As mentioned above, only the Research Coordinator will know which group the participant is randomized into. The PI will remain blinded throughout the study.
