Genetic Toxicity Assessment: Employing the Best Science for Human Safety Evaluation Part I: Early Screening for Potential Human Mutagens

摘要

Results of genetic toxicology tests are used by FDA's Center for Drug Evaluation and Research as a surrogate for carcinogenicity data during the drug development process. Mammalian in vitro assays have a high frequency of positive results which can impede or derail the drug development process. To reduce the risk of such delays, most pharmaceutical companies conduct early non-GLP (good laboratory practices) studies to eliminate drug candidate with mutagenic or clastogenic activity. Early screens include in silico structure activity assessments and various iterations of the ultimate regulatory mandated GLP studies.
