NCT03151967

Brief Summary

The purpose of this research is to see whether LACTIN-V (Lactobacillus crispatus CTV-05) is an effective method of preventing recurrent urinary tract infections (UTI's) and to learn the side effects of LACTIN-V. LACTIN-V is a vaginal applicator that contains Lactobacillus crispatus, an organism found naturally in the vaginas of healthy women. Lactobacillus bacteria are thought to help prevent other bacteria such as E. coli from causing UTI's. This is a double blind study comparing active product to a placebo (inactive vaginal applicator without any medicine).
