Official title

The Efficacy of Probiotics to Reduce Antepartum Group B Streptococcus Colonization

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This study is a randomized double blind, placebo controlled trial to determine the efficacy of an oral probiotic in reducing antenatal Group B Streptococcus colonization. The goal of this study is to demonstrate that women in the probiotics group will experience; (1) reduced GBS prenatal colonization at 36± 2 weeks gestation and lower levels of GBS colonization, (2) less need for intrapartum antibiotic prophylaxis and (3) fewer prenatal gastrointestinal symptoms compared to women in the placebo group. Intrapartum measures were added and IRB approved in Feb 2020 as a pilot and feasibility substudy. The goals of this study are as follows: (1) Explore the effect of antepartum exposure to Florajen3 on maternal and neonatal residual GBS and the maternal microbiome. We anticipate that (1)At the time of labor, more women in the probiotics group will test negative for GBS on vaginal to rectal swabs compared to those in the placebo group and (2) Fewer neonates born to women in the probiotic group will have GBS on nasal-oral pharynx cultures within several hours of birth compared to those born to neonates in the control group.
