Exactly.
I know everyone thinks pharma is the devil (and they largely are), but they're the only ones out there providing funding for trials.
I'm currently the PI on 4 trials. 2 industry sponsored, 2 are IITs that I wrote. One of the IITs is diagnostic only and is funded by a biotech company. The only thing it involves on the clinical side is a blood draw at the time of diagnosis. The other is a study of high-dose Vitamin D supplementation as an adjunct to chemotherapy in colon cancer. It is funded by a foundation grant that covers the drug, quarterly Vitamin D levels for 1 year and about $5K worth of research staff time.
The 2 industry sponsored trials provide free drug, pay for all clinic visits (but not labs or imaging which are standard of care) and pay about $8-10K/patient we enroll. This covers the salary/benefits/indirect costs such as office space and computers for the half dozen research coordinators/assistants that are required to make it all work. And when I say that money covers those costs, what I mean is that, over the 2 trials that I have, as well as the 15-20 other trials that the other docs in my group have, we can pay those people.
Bottom line, any kind of interventional/drug trial, is going to require industry money. And the timeline for getting a trial going is usually on the order of 6-18 months. Not the sort of thing an IM chief is going to be able to do.
