Reproductive Toxicity Segment II Embryo Fetal Development Testing
In the pharmaceutical and chemical industries, ensuring the safety of new products is paramount. One critical aspect of this safety evaluation involves reproductive toxicity testing to assess potential adverse effects on embryo-fetal development during pregnancy.
Reproductive Toxicity Segment II Embryo-Fetal Development Testing focuses specifically on identifying developmental toxicants that may cause harm to the unborn fetus or affect postnatal development if exposure occurs. This segment builds upon earlier segments of reproductive toxicity testing, providing a more comprehensive evaluation by examining specific teratogenic effects and potential developmental anomalies.
The Segment II test evaluates whether maternal exposure to a substance can lead to structural malformations, growth retardation, functional defects, or death of the embryo/fetus. It is essential for pharmaceutical companies to demonstrate the safety profile of their products before they reach the market. Regulatory bodies such as the FDA and EMA require this testing to ensure public health.
The test involves administration of the substance under evaluation to pregnant animals (typically rats or rabbits) during a critical period of organogenesis, which usually corresponds to gestation days 6-15 in rodents and days 10-20 in rabbits. The primary objectives are to observe developmental endpoints such as fetal viability, birth defects, litter size, and postnatal growth.
The data collected from Segment II testing provides critical insights into the risk-benefit profile of a substance. It helps pharmaceutical companies make informed decisions about further development or potential modifications needed for clinical trials. Regulatory agencies use this information to ensure that only safe drugs enter the market.
