Adverse Event Reporting Online Form

As part of our commitment to enable safe, accountable, high-quality FMT treatments and ensure compliance with FDA safety reporting regulations, all clinical partners and investigators that utilize OpenBiome FMT material are required to report adverse events (AEs) to OpenBiome and possibly to the FDA. 

If you suspect that one of your patients or study subjects experienced a serious adverse event following his or her FMT, please complete the following online AE report in its entirety. Upon submission, your report will go to the Pharmacovigilance and Safety Team at OpenBiome. We will then work with you to determine any actionable steps required. 

If you have any additional questions, please also contact us at or call 617-575-2201, option 9. We are more than willing to discuss the specifics of your case in more detail.
