Abstract
Several new approach methodologies (NAMs) for developmental toxicity (Dev Tox) testing are being used by pharmaceutical companies for derisking or for exploring Dev Tox mechanisms. Regulatory adoption of these NAMs-based approaches as being adequate for Dev Tox risk assessment has been more challenging, due, in part, to dynamic changes in the conceptus and placenta throughout development and the impact of the pharmaceutical on the mother’s physiology, which may also have an embryo-fetal impact. Still, there is currently a recognition by Health Authorities that there are certain contexts-of-use under which Dev Tox NAMs can provide information that is adequate to inform risk. This has been adopted in the 3rd revision of the ICH S5 guideline, which provides a path to qualify Dev Tox NAMs for regulatory decision making. Despite this opportunity, pharmaceutical companies rarely submit Dev Tox NAMs to Health Authorities for qualification or with intent to support regulatory decision making. This may be in part due to the need for a greater understanding of the biological relationship between currently available Dev Tox NAMs and in vivo outcome, applicability domain, translatability, predictivity, and that these NAMs do not cover the complete scope of embryo-fetal development. Furthermore, there is a lack of Dev Tox NAMs data visibility to Health Authorities. To use Dev Tox NAMs for regulatory decision making, more data sharing with Health Authorities and further understanding the applicability domain of these methodologies are needed.
期刊介绍:
Drawing from a large number of disciplines, Reproductive Toxicology publishes timely, original research on the influence of chemical and physical agents on reproduction. Written by and for obstetricians, pediatricians, embryologists, teratologists, geneticists, toxicologists, andrologists, and others interested in detecting potential reproductive hazards, the journal is a forum for communication among researchers and practitioners. Articles focus on the application of in vitro, animal and clinical research to the practice of clinical medicine.
All aspects of reproduction are within the scope of Reproductive Toxicology, including the formation and maturation of male and female gametes, sexual function, the events surrounding the fusion of gametes and the development of the fertilized ovum, nourishment and transport of the conceptus within the genital tract, implantation, embryogenesis, intrauterine growth, placentation and placental function, parturition, lactation and neonatal survival. Adverse reproductive effects in males will be considered as significant as adverse effects occurring in females. To provide a balanced presentation of approaches, equal emphasis will be given to clinical and animal or in vitro work. Typical end points that will be studied by contributors include infertility, sexual dysfunction, spontaneous abortion, malformations, abnormal histogenesis, stillbirth, intrauterine growth retardation, prematurity, behavioral abnormalities, and perinatal mortality.
