The NIH Microphyiological Systems Program: In Vitro 3D Models for Safety and Efficacy Studies
Danilo Tagle,
Associate Director for Special Initiatives,
National Institutes of Health
Approximately 30% of drugs have failed in human clinical trials due to adverse reactions despite promising pre-clinical studies, and another 60% fail due to lack of efficacy. A number of these failures can be attributed to poor predictability of human response from animal and 2D in vitro models currently being used in drug development. To address this challenges in drug development, the NIH Tissue Chips or Microphysiological Systems program is developing alternative innovative approaches for more predictive readouts of toxicity or efficacy of candidate drugs. Tissue chips are bioengineered 3D microfluidic platforms utilizing chip technology and human-derived cells and tissues that are intended to mimic tissue cytoarchitecture and functional units of human organs and systems. In addition to drug development, these microfabricated devices are useful for modeling human diseases, and for studies in precision medicine and environment exposures. Presentation will elaborate in the development and utility of microphysiologicals sytems and in the partnerships with various stakeholders for its implementation.
