Brief Summary
The goal of this clinical trial is to evaluate the feasibility of the randomized controlled trial (RCT). Secondary objectives include comparing the microbiota of preterm babies born after premature rupture of membranes across study groups. To achieve this, participants will be asked to:
- Use the vaginal study product from the time of membrane rupture until delivery
- Keep a diary documenting their symptoms and treatment adherence
- Provide vaginal secretion samples and stool samples from their baby

Outcome Measures
Primary Outcomes (3)
Recruitment rate
To assess the feasibility of the study, each local site team will complete a dashboard documenting every individual met and informed about the study. This dashboard will be used to calculate the recruitment rate, using the formula: Recruitment rate = (Number of eligible patients - Number of patients who did not consent) / Number of eligible patients Additionally, the dashboard will track reasons for acceptance or refusal.
7 months
Feasability dashboard
The attrition rate will be explored to assess feasability of the study. Attrititon rate = (# participants who dropped out / total of participants).
7 months
Treatment adherence
Finally, number of caps took during the treatment phase will be reported to explore the adherence of treatment.
7 months
