Quoting from the April 6th article by Ed Sealover:
"Colorado was home to more than 3,000 clinical drug trials in the past 12 years — a little-known but increasingly important factor in the state’s health care economy.
A new study out by the Pharmaceutical Research and Manufacturers of America (PhRMA) doesn’t detail the economic impact of such trials. Nevertheless, state officials estimate that impact could be in the billions of dollars, and they’re promoting Colorado as a place for biotech and medical research expansion...
...It also can help to develop Colorado’s growing biopharmaceutical industry, which includes about 300 companies employing more than 5,410 people, according to the Colorado Bioscience Association. A 2008 study by Archstone Consulting of Miami found that biopharmaceutical companies invested $379.9 million in research and development in Colorado that year."
