简要总结
The MOTIF@ FRESH trial will assess the safety and efficacy of "vaginal microbiome transplantation" (VMT). Healthy females will be enrolled to donate vaginal fluid which will be processed and transplanted in females with a history of recurrent bacterial vaginosis (BV), treated with antibiotics.
详细描述
The proposed randomized, double-blinded, placebo-controlled trial is to evaluate the safety of vaginal microbiota transplantation (VMT) in women with recurrent bacterial vaginosis (BV). The study is based in South Africa, at the FRESH (Females Rising through Education, Support, and Health) Clinical Research Site (CRS) located in the Umlazi Township of Durban. The aim of the trial is to assess the ability of antibiotic treatment plus VMT to establish a Lactobacillus-dominant vaginal community. The underlying hypothesis is that the VMT will lead to less inflammation and higher prevalence of vaginal Lactobacillus compared to antibiotics alone. The transplant material will be vaginal fluid collected from healthy donors (also known as Donors) using a disposable menstrual cup.
Donors are defined as participants with Nugent scores <4. Over a 16-week period, donors will provide vaginal fluid via softcups (referred to as "donations"). All donations will undergo extensive testing for sexually transmitted infections (STIs) and other infections. Donations that test negative for specified infections will be processed to generate vaginal microbial transplantation (VMT) doses for recipients.
Recipients are defined as participants with Nugent scores ≥4. Because the HPV vaccine is not routinely administered in South Africa, all recipients without documented proof of prior HPV vaccination will receive the HPV vaccine at least 30 days prior to the intervention. The intervention includes the standard of care for bacterial vaginosis in both the U.S. and South Africa: oral metronidazole (MTZ), administered twice daily for seven days. Following completion of the MTZ course, recipients will receive three VMT doses administered over approximately 1.5 weeks. Recipients will be randomized in a 2:1 ratio to receive either VMT or placebo and will be followed for six months post-intervention.
