Report An Adverse Event

As part of our commitment to enable safe access to accountable, high-quality investigational FMT preparations and ensure compliance with FDA safety reporting regulations, all clinical partners and investigators that utilize investigational FMT material distributed by OpenBiome 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 has experienced a serious adverse event following their investigational FMT, please complete the following online AE report in its entirety. Upon submission, your report will go to the Patient Safety Team at OpenBiome and MMS, a contract research organization that provides support as our pharmacovigilance contractor. 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.

Please provide a phone number where you can be easily reached by a member of the Clinical Assessment and Safety team to conduct an investigation of this adverse event.
