Recommendations related to probiotic research

U.S. Food and Drug Administration
  • Provide specific guidance for how to substantiate structure/function claims and health claims for probiotic foods, dietary supplements, and medical foods

  • Provide realistic guidance specific to IND applications for human studies investigating probiotic products

  • Provide investigator-initiated IND exemptions if regulation allows these

  • Consider extending health claim status (i.e., reduction of risk of disease) to acute diseases and health conditions, not just chronic, diet-related diseases

National Institutes of Health
  • Provide a service to investigators to stimulate study rigor

  • Continue supporting patient-oriented clinical trials of probiotics, even if they need to be preceded by Phase 1 studies

Probiotic food and supplement manufacturers
  • Understand FDA labeling regulations

  • Ensure that structure/function claims are accurately substantiated and are worded so as not to be understood as an unauthorized health or drug claim

  • Develop sufficient evidence to meet requirements to petition FDA for health claims

Researchers
  • Consult with FDA early when contemplating clinical research to determine whether IND regulations apply to their particular study

  • Request a pre-IND application meeting when an IND application is required to facilitate compliance with regulations and identify regulatory challenges before investing time and resources to submit an IND application

  • Follow FDA guidelines for IND content

  • Engage individuals experienced with IND application processes to help them with IND applications for probiotic studies

  • Maintain a good working relationship with the manufacturer or master file holder in order to adequately address the CMC section of the IND application

  • Know the characteristics, potency, purity, and stability, as well as safety, of their probiotic test agents

  • Follow the CONSORT guidelines in reporting study results
