CSP MISSION
To advance the health and care of Veterans
through collaborative research studies that
produce innovative and effective solutions to
national healthcare problems.
CSP OVERVIEW
• CSP is a national infrastructure for sponsoring, developing
& executing:



Multi-site clinical trials
Epidemiological & population research
Genomics research
• First Cooperative Study conducted in 1940s on
streptomycin for treating tuberculosis in WWII veterans

Program formally established in 1972
• Over 175 clinical trials and observational studies
completed including landmark studies in cardiovascular
disease / cardiovascular surgery, infectious diseases,
surgery, gastroenterology, mental health, oncology, and
endocrinology.

VA Genomic Medicine Program
• In 2006, the Department of Veterans Affairs
launched the Genomic Medicine Program:
to examine the potential of emerging
genomic technologies
 to optimize medical care for veterans
 to enhance the development of tests and
treatments for relevant diseases

Genomic Medicine Program Con’t
• Genomic Medicine Program Advisory
Committee
• Veterans’ Consultation Project

83% supported; 71% willing to participate
• Scientific Projects
 Investigator-initiated
 Large scale cohorts (SMI, PTSD, ALS)
 Million Veteran Program (non-disease
based)
Infrastructure Development

Expansion of Biorepository



IT and Informatics


CSP DNA Bank (~30,000 samples)
Expansion to ~4M; robotic store; automation
Genomic Information System for Integrated
Sciences(GenISIS)
Pharmacogenomics Laboratory (PAL)

Established in 2007
Pharmacogenomics Analysis
Laboratory (PAL)
•CLIA88 approved laboratory with capacity to
conduct medium to high throughput genotyping
and gene expression assays.
•Support ongoing and future pharmacogenomics
observational studies and clinical trials.
•Improving treatment of most illnesses by
reducing toxicity and increasing efficacy of drugs
by facilitating optimal treatment selection,
appropriate dose individualization, and drug
discovery.
