A Randomized, Double-Blind, Parallel-Group, Multicenter Clinical Study of <b><i>Escherichia coli</i></b>-Lyophilized Lysate for the Prophylaxis of Recurrent Uncomplicated Urinary Tract Infections

Abstract

Our results did not demonstrate a preventive effect of OM-89S compared to placebo. This may be due to the low number of UTIs that occurred during the study, the high number of protocol violations, and/or the modified manufacturing process used for OM-89S.
