It might be quite difficult for you to run a clinical trial. There are likely more opportunities in the systems that surround clinical trials (patient education, patient/doctor communications, training).
If you don't have a background in biostatistics, start learning. Biostatistics is the interface between the FDA and the clinical trial team.
At the time I had allergic asthma and was getting conventional treatment (inhaled steroids, immunotherapy) so I was a control in a study of the effects of the new drug Xolair.
For five years I got all my yearly diagnostics done for free, plus a yearly appointment -- in fact it was better than free because they'd pay me about $40.
Funny enough I am less bothered by asthma now, maybe the immunotherapy worked.
I think I asked the wrong question.
