What is the study medicine (CP101)?

  • CP101 is an orally-administered, encapsulated medicine, taken in a single dose.
  • CP101 is an investigational product that is still being tested and is not approved for commercial sale. As such, CP101 can only be taken as part of the clinical trial – your physician cannot prescribe it to you.
  • CP101 builds on the clinical development of Crestovo’s academic collaborators, Dr. Alexander Khoruts and Dr. Michael Sadowsky, who developed an early-stage oral formulation of a microbiota-based product in 2014.
