Americans For Medical Advancement (AFMA) is a 501(c)(3) science-based patient advocacy organization dedicated to improving policy and decision-making regarding the use of the animal model in biomedical research and drug testing. They oppose the use of animals only as models for predicting human response. For example, ADMET (absorption, distribution, metabolism, elimination, and toxicity), efficacy testing, and medical research where results from animal-based research are assumed predictive for humans. Scientifically, such uses are known as using animals as causal analogical models or as predictive models.
