CAN WE DEVELOP A COHERENT STRATEGIC FRAMEWORK FOR BIOMEDICAL RESEARCH?
GLOBAL Public Health Challenges Acute to Chronic Conditions Aging Population Health Disparities Emerging and Re-emerging infectious Diseases Emerging Non communicable diseases
Need to Transform Medical Research in the 21stCentury 20th Century 21st Century Treat disease when symptoms appear and normal function is lost Intervene before symptoms appear and preserve normal function for as long as possible Did not understand the molecular and cellular events that lead to disease Understanding preclinical molecular events and ability to detect patients at risk Expensive in financial and disability costs Orders of magnitude more effective

Screening Optimization Pre-clinical Clinical Examples of key roadblocks Insufficient read-out on safety and toxicology Lack of standardization and efficiency of clinical trials Validation of complex diseases Some opportunities for improvement Biomarkers, Animal models, Systems biology, Chemical genomics Biomarkers, Animal models, Data sharing Biomarkers, Clinical training, Regulatory harmonization, Informatics
What is the NIH Roadmap for Medical Research? • A framework of scientific priorities that the NIH as a whole must address in order to optimize its entire research portfolio. • A vision for a more efficient, innovative and productive system of research into health, mechanisms of disease, and related behaviors.
The NIH Roadmap for Medical Research New Pathways to Discovery Re-engineering the Clinical Research Enterprise Research Teams of the Future
Complexity of Biological Networks • Multiple levels of cross-talk between molecular pathways • Many molecular targets part of intricate signaling networks • Novel experimental and theoretical concepts needed

Human Genome Project and HapMap Are Complete: Where Do We Go From Here? • Plummeting cost of DNA sequencing • New discoveries accelerating revolution of the practice of medicine • Genes, Environment, and Health Initiative • Identify roots of 10 most common diseases • Devise new ways of monitoring personal environmental exposures
Advances in Age-related Macular Degeneration (AMD) • AMD is the leading cause of blindness in people over age 60 • Variations in certain genes involved in inflammation can predict the risk of developing AMD • 56 % of the unaffected individuals had a variant that conferred protection to AMD • 74 % of those with AMD had no protective variants Normal vision Vision affected by AMD
New Discoveries Make it Possible to “Personalize” Cancer Treatment Impact: • 100,000 women each year can make a more informed choice • 70,000 women do not have to undergo chemotherapy • Reduces routine cost of treating these patients • For each patient year of life gained, we save ~$8,000 Identified 16 informative genes Test tumor samples for mutations in these genes Predict which patients need chemotherapy
Pharmaco-Genomics: Managing Human Variability • Pharmaco-Genetics Research Network (PGRN) • National collaboration of scientists studying the effect of genes on people's responses to a wide variety of medicines • Pharmaco-Genetics & Pharmaco-Genomics Knowedge Database (PharmGKB) • Integrated knowledge base for pharmacogenetics linking phenotypes and genotypes http://www.nigms.nih.gov/Initiatives
