Abstract: Background: Facing critically low return per dollar invested on clinical research and clinical care, the
American biomedical enterprise is in need of a significant transformation. A confluence of high-throughput “omic”
technologies and increasing adoption of the electronic health record has fueled excitement for a new paradigm
for biomedical research and practice. The ability to simultaneously measure thousands of molecular variables
and assess their relationships with clinical data collected during the course of care could enable reclassification
of disease not only by gross phenotypic observation but according to underlying molecular mechanism and
influence of social determinants. In turn, this reclassification could enable development of targeted therapeutic
interventions as well as disease prevention strategies at the individual and population levels. Methods/Design:
The MURDOCK Study consists of distinct project “horizons” or stages. Horizon 1 entailed the generation and
analysis of molecular data for existing large, clinically well-annotated cohorts in four disease areas. Horizon 1.5
involves creating and maintaining a 50,000-person, community volunteer registry for biomarker signature
validation and prospective studies, including integration of environmental and social data. Horizon 2 leverages
and prospectively recruits Horizon 1.5 volunteers, and extends the study to additional disease areas of interest.
Horizon 3 will expand the study through regional, national, and international partnerships. Discussion: The
MURDOCK Study embodies a new model of team science investigation and represents a significant resource for
translational research. The study team invites inquiries to form new collaborations to exploit the rich resources
provided by these biospecimens and associated study data. (AJTR1206004).
