Is the FDA killing research?

By focusing so much on safety, the FDA may be stifling R&D:

“Who is going to bring a new, improved version of Avandia to market,” asks Ruffolo, given the likely trial-size FDA is going to request? How will any company be able to prove that their drug doesn’t have the safety issues associated with Avandia, if these (whether or not they are real) only become apparent from Steve Nissen’s meta-analysis of trials involving 28,000 patients?

No drug is risk-free, and no company-sponsored clinical trial can feasibly replicate real-world drug usage over a number of years. Yet people [politicians, patient groups, Public Citizen, and now FDA] “are demanding absolute positive safety,” Ruffolo tells us.
