Inclusion Criteria:

  • Subjects must provide written informed consent prior to any study related procedures being performed.
  • Female subjects must have a clinical diagnosis of bacterial vaginosis, defined as having the presence of "clue cells" > 20% of the total epithelia cells on microscopic examination of a saline "wet mount" and all of the following criteria: Off-white (milky or grey), thin, homogeneous discharge; pH of vaginal fluid > 4.7; a positive 10% KOH "whiff test".
  • Subjects must be 18 years of age or older with no known medical conditions that, in the investigator's opinion, may interfere with study participation.
  • Women of child bearing potential must have a negative urine pregnancy test result upon entry into the study.
  • Subjects must agree to abstain from sexual intercourse throughout the first 7 days of the study. Following the first 7 days, subjects must agree to use a non-lubricated condom when engaging in sexual intercourse.
  • Subjects must be willing to abstain from alcohol ingestion during the 5 day treatment period and for 1 day afterward.
  • Subjects must agree to refrain from the use of intra-vaginal products throughout the study (e.g., douches, feminine deodorant sprays, spermicides, lubricated condoms, tampons, and diaphragms).

Exclusion Criteria:

  • Subjects with known or suspected other infectious causes of vulvovaginitis (e.g. candidiasis, Trichomonas vaginalis, Chlamydia trachomatis, Neisseria gonorrhoeae, active Herpes simplex or human papilloma virus, or any other vaginal or vulvar condition, which in the investigator's opinion, would confound the interpretation of the clinical response).
  • Subjects with a Gram's stain slide Nugent score <4.
