S5(R3) Detection of Toxicity to Reproduction for Human Pharmaceuticals; International Council for Harmonisation; Draft Guidance for Industry; Availability

The Food and Drug Administration (FDA or Agency) is announcing the availability of a draft guidance entitled ``S5(R3) Detection of Toxicity to Reproduction for Human Pharmaceuticals.'' The draft guidance was prepared under the auspices of the International Council for Harmonisation (ICH), formerly the International Conference on Harmonisation. The draft guidance replaces the existing guidance entitled ``S5(R2) Detection of Toxicity to Reproduction for Human Pharmaceuticals.'' The draft guidance is intended to align with other ICH guidances, elaborate on concepts to consider when designing studies, and identify potential circumstances in which a risk assessment can be made based on preliminary studies. It also clarifies the qualification and potential use of alternative assays.
