The Food and Drug Administration (FDA or Agency) is announcing the availability of a draft guidance for industry entitled “Recommended Followup Testing for an Ames-Positive Drug (Active Ingredient) or Metabolite To Support First-in-Human Clinical Trials With Healthy Subjects.” This draft guidance makes recommendations on followup testing for Ames-positive active ingredients in circumstances when a sponsor decides to continue development. The guidance recommends a consistent process of followup testing and evaluation that first should be conducted for an Ames-positive active ingredient before proceeding with first-in-human (FIH) trials in healthy human subjects. These recommendations are intended to potentially help address and lower safety concerns before proceeding with FIH trials in healthy human subjects.
