Animal Models of Pregnancy to Address Medical Countermeasures (MCM) for Influenza and Chemical, Biological, Radiological and Nuclear Threats in the 'At-Risk' Population of Pregnant Women
Description: The Pandemic and All Hazards Preparedness Act established in 2006 called for the implementation of national preparedness for the public health and medical needs of "at risk individuals" in the event of a public health emergency. There is a priority to advance research and development of qualified countermeasures and qualified pandemic or epidemic products that are likely to be safe and effective with respect to the at risk population of pregnant women. Pregnancy leads to significant physiological changes in women to accommodate the developing fetus, including cardiovascular changes and renal clearance, all of which may effect changes in which a drug is absorbed, distributed, metabolized and eliminated from the body. Because of the ethics in researching on humans and unborn babies, an animal model must be developed for testing. In order to find an animal model that will model most closely to a human, a literature review will be done, followed by this expert public workshop. The public workshop will used to gather experts in the fields of teratology, developmental toxicology, reproductive toxicology and pharmacokinetic modeling to define the experimental parameters most appropriate to include in the development of an animal model. With the information gathered from the workshop, an experimental protocol will be developed, reviewed by international experts and conducted at the National Center for Toxicological Research (NCTR). This series of experiments may also serve as a model for the evaluation of other medical countermeasures in the pregnant women and the fetus.
Public Health Benefit: Pregnant women will be given safer and more effective dosing regiments of anti-influenza drugs and related drugs based on the data gathered in pregnant animal models.
