Brief Summary:

Vaginal Microbiome Transplantation (VMT) may be beneficial in treating the most severe cases of recurrent and antibiotics-nonresponsive cases of BV. Recently, we completed a preliminary study in which we treated patients with recurrent and antibiotics-non-responsive, intractable BV, with VMT from healthy donors [Lev-Sagie, Nature Medicine 2019]. Four VMT recipients in this preliminary study featured a significant improvement of both clinical symptoms and dysbiotic vaginal microbiome composition and function, which persisted over a long follow-up period, while one recipient featured a partial remission.

The proposed study is designed as a placebo, randomized controlled trial, and is aimed to further assess whether VMT may serve as a viable option in symptomatic, intractable BV. In the suggested study, we plan to compare transplantation of: 1) vaginal fluid from healthy donors, and 2) autologous transplantation, of the patient's own vaginal fluid.

Arm Intervention/treatment
Active Comparator: VMT recipients

In order to prevent transfer of pathogens, sperm, or antibiotic-resistant commensals we will establish a "vaginal fluid bank" in which samples from suitable donors will be kept for future use:

  • Donors will be screened using a questionnaire addressing risk factors for potentially transmissible infections, undergo screening for cervico-vaginal infections, cervical cytology screening, and serology analysis for transmittable infections {see detailed screening in Lev-Sagie et al. Nat Med. 2019;25(10):1500-1504. doi: 10.1038/s41591-019-0600-6.}
  • The collected samples for VMT will be examined for bacteria,viruses and sperm.

Before transplantation, patients will be treated with intravaginal antibiotics. A frozen specimen will be thawed at room temperature and will be placed in the patient's vagina.

Following VMT, patients will be evaluated every 14 days for the first 2 months, then every month for additional 10 months.

Biological: Vaginal Microbiome Transplantation (VMT)
Healthy donors vaginal fluid is introduced into recipients' vagina to replace their indigenous disease-associated microbiome

Placebo Comparator: Placebo

Vaginal fluid of all recipients will be collected before initiation of the study using the same protocol, will be clearly labeled and will be kept frozen in similar conditions. These samples will be used in the placebo arm for autologous vaginal fluid transplantation.

Before transplantation, patients will be treated with intravaginal antibiotic.

Following Placebo, patients will be evaluated every 14 days for the first 2 months, then every month for additional 2-4 months.

After 4-6 months, patients who initially received placebo will be offered a VMT in case they are still symptomatic and fulfill inclusion criteria, in an open-label phase.

Biological: Placebo

Primary Outcome Measures :
  1. Clinical parameters- patient's complains [ Time Frame: 12 months ]

  3. Vaginal fluid microscopy [ Time Frame: 12 months ]
    Presence of Lactobacillus-dominant microbiome on microscopy

  4. Microbiome composition [ Time Frame: 12 months ]
    Characterization of the vaginal microbial community using shotgun analysis and16S rRNA sequencing
