LACTIN-V, also known as CTV-05 or as Lactobacillus crispatus CTV-05, is a live biopharmaceutical medication containing a strain of Lactobacillus crispatus (L. crispatus) which is under development for the treatment of urinary tract infections (UTIs) and bacterial vaginosis (BV).[1][2] It is administered intravaginally and is described as the first vaginal microbiome (VMB)-based live biotherapeutic product (LBP).[2] Depletion of hydrogen peroxide (H2O2)-producing Lactobacillus strains such as Lactobacillus crispatus in the vagina has been strongly associated with BV and UTIs.[2] Most commercially available probiotic Lactobacillus strains are not vaginal strains and do not appear to improve vaginal or urinary health outcomes.[2] The Centers for Disease Control and Prevention (CDC)'s Sexually Transmitted Infections Treatment Guidelines (2021) noted that intravaginal LACTIN-V produced a considerably lower recurrence of BV following initial antibiotic treatment with metronidazole in a randomized controlled trial.[3][4] However, the guidelines also noted that LACTIN-V is not yet Food and Drug Administration (FDA)-approved or commercially available.[3] As of December 2021, LACTIN-V is in phase 2/3 clinical trials for the treatment of UTIs and is in phase 2 trials for the treatment of BV.[1] It was originated by GyneLogix and is under development by Osel Inc., the National Institute of Allergy and Infectious Diseases, and other organizations.[1]
