Vaginal microbiome treatment for women with previous failed embryo transfer
Part of Infections, Women’s health & pregnancy clinical trials.
This study tests a vaginal treatment (FB301) to see if it helps improve the balance of bacteria in the vagina before a frozen embryo transfer. It may help women who have had a prior failed frozen embryo transfer and have a specific type of vaginal bacterial imbalance.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are a woman aged 18 to 45 years with regular periods.
- You have had at least one previous frozen embryo transfer that did not lead to pregnancy within the last 3 years (and it wasn't due to male infertility or blocked fallopian tubes).
- You are willing to go through a mock frozen embryo transfer cycle and later have a real frozen embryo transfer with one good-quality embryo.
- You have a vaginal swab showing a specific type of bacterial imbalance.
- Your recent fertility blood tests show FSH below 12 and AMH above 1.
- Your BMI is between 18 and 42, and you are willing to follow certain restrictions (like no vaginal products or swimming) during the study.

This trial tests a new way to find and treat vaginal infections early in pregnancy to help prevent preterm birth. It may help women who have had a preterm baby or a late miscarriage before.
This study looks at how bacteria in the vagina and lining of the uterus change during the “luteal phase” (the time after ovulation and before a pregnancy test) in people using frozen embryo transfers. It may help researchers understand what conditions support embryo implantation and pregnancy in assisted reproduction.
This trial tests a pre-treatment with chlorhexidine and/or metronidazole before a new drug called FB301 in women with bacterial vaginosis (BV). It aims to see if this combination is safe and works well.
This trial tests whether transferring vaginal bacteria from healthy donors to women with bacterial vaginosis can improve vaginal health. It may help reduce symptoms and prevent future infections.
This Phase 3 study tests whether adding micronized progesterone during frozen embryo transfer cycles helps support embryo implantation and pregnancy. You may benefit if your care team is already preparing the uterus with hormone therapy for a blastocyst transfer.
This study looks at how the natural community of germs (microbiome) in the vagina might affect the chance of becoming pregnant after transferring a genetically normal embryo. It could help doctors understand if the vaginal environment plays a role in IVF success.
