The lack of participation in clincial trials

In a recent article at the News & Observer, the newspaper serving Raleigh, North Carolina, Dr. Susanne B. Haga writes about the current lack of participation in clinical trails that is currently slowing down the discovery and development in the drug industry. She focuses specifically on cancer trials, which currently only have 3% of adult cancer patients participation. As for other clinical trials, only 1/2 of them are meeting specific patient trial goals. May trials go undone, leaving many medical questions up in the air.

How do you feel about the current state of patient recruitment in clinical trials?
