Brief Summary:
Male partners of womoen with recurrent bacteria vaginosis are randomized to treatment with metronidazole or placebo to compare the rates of recurrent BV in the women

Condition or disease Intervention/treatment Phase
Recurrent Bacterial Vaginosis Drug: Metronidazole (male partner) Other: Placeob (male partner) Phase 3

Detailed Description:

This study will be performed as a phase III randomized, double-blinded trial to evaluate the efficacy of 1) metronidazole 500 mg PO BID for 7 days versus 2) placebo capsules alone for treatment of the male sexual partner of women with recurrent BV. The primary outcome is the rates of recurrent BV between these two groups. Although this is a phase III study we will carefully monitor potential toxicity in the males since it is currently not standard of care to treat males for this indication.

Women with symptomatic BV defined by Amsel criteria 1 and no evidence of STD will be invited to participate. Inclusion criteria are that the woman be at least 18 years of age, heterosexual, have symptoms of vaginal odor and/or discharge, meet the modified clinical (Amsel) criteria for BV (all must have a vaginal pH of >4.5, a positive whiff test, and clue cells to be eligible), have an enrollment Nugent score of 7 or greater, and a history of 2 or more episodes of BV in the previous year. She must have a regular current sex partner who would be willing to participate. We will exclude women who have had recurrent BV for greater than 3 years as well as women who have failed previous treatment studies since it is likely that these women are having recurrent BV as a result of relapse of the BV biofilm as opposed to reinfection.

Follow-up visits will be conducted at day 21, 8 and 16 weeks. At each follow-up visit, a questionnaire will be administered, diary reviewed, pelvic examination conducted and specimens (Gram stain, Amsel criteria, G vaginalis culture and detection of novel organisms) obtained as done at the enrollment visit. Participants will be asked to return the medication packages, a standard way of assessing adherence to the regimen. Cure will be ascertained using the clinical criteria for BV of Amsel 1 as well as the Nugent scoring system 16. The persistence or disappearance of specific organisms will be analyzed in relationship to these standard definitions of cure. Women who fail initial therapy or have recurrence of symptomatic BV during the course of the study will be re-treated with 7 days of metronidazole and dropped from the study at that time. Any woman found to have a positive screening test for gonorrhea or chlamydia will be treated appropriately and instructed to notify her partner of the need to be treated. Women with intercurrent vaginal yeast infections, which may occur, will be treated with oral fluconazole and continued in the study. Women with a positive culture for trichomonas will be dropped from the study as their male partners will require treatment with metronidazole.

Male Study Procedures

Males referred by their female sexual partner will be seen within 48 hours of enrollment of the female. Males will be consented and asked behavioral and historical questions using a gender appropriate questionnaire, with special emphasis on number of current sexual partners. A couple verification screening tool will be utilized to be certain they are current sexual partners48. The confidentiality of their answers will be emphasized. They will be examined and a urethral swab specimen obtained to be used for G vaginalis culture and then archived. Following the swabs, two external swabs from the coronal sulcus and a 10 ml first void urine specimen will be obtained. These specimens will also be used for G vaginalis culture and archived for possible use in detection of novel organisms. The urine will also be used for NAATS for N gonorrhoeae and C trachomatis and for the determining the presence or absence of Gardnerella biofilm24. They will then be randomized to one of two treatment arms:

  1. Metronidazole 500 mg PO twice a day for 7 days .
  2. Placebo capsules PO twice a day for 7 days.

Both arms will also contain an instruction sheet on metronidazole.

Arm Intervention/treatment
Experimental: Metronidazole
Male Partner: metronidazole 500 mg PO BID x 7days Female Partner: metronidazole 500 mg PO BID x 7days
Drug: Metronidazole (male partner)
500 mg PO BID for 7 days

Placebo Comparator: Placebo
Male Partner: one tablet PO BID for 7 days Female Partner: metronidazole 500 mg PO BID x 7days
Other: Placeob (male partner)
matching placebo capsules PO BID for 7 days




Primary Outcome Measures :
  1. number of female partners whose male partners received Metronidazole versus females whose male partners did not receive metrodiazole with recurrence of BV in the female [ Time Frame: 16 weeks post start of receipt of study drug ]

    the female partners will be assessed for recurrence/persistence of BV. tRecurrence/persistence is measured by - Positive 3 - 4 Amsel criteria (vaginal pH > 4.7, clue cells, positive whiff test, homogenous discharge); Nugent score >3

    No Recurrence/Persistence is measured by:

    - Presence of 0 -2 Amsel criteria; Nugent score 0-3.



Secondary Outcome Measures :
  1. Number of couples with concordance of biotypes/strains of Gardnerella vagininalsis [ Time Frame: baseline ]
    The biotype/strain of Garnerella vaginalsis will be measured for both partners

  2. Time to recurrence of BV in women whose partner received metronidazole versus females whose partners did not receive metronidazole [ Time Frame: from the end of week 1 up to 16 weeks ]
    time to recurrence measured in days
