More than a quarter of the Food and Drug Administration employees who approved cancer and hematology drugs from 2001 through 2010 left the agency and now work or consult for pharmaceutical companies, according to research published by a prominent medical journal. [Dr. Vinay] Prasad and his colleague Dr. Jeffrey Bien ... tracked 55 FDA reviewers in the hematology-oncology field from 2001 through 2010, using LinkedIn, PubMed and other publicly available job data. The researchers found that of the 26 reviewers who left the FDA during this period, 15 of them, or 57 percent, later worked or consulted for the biopharmaceutical industry. Put another way, about 27 percent of the total number of reviewers left their federal oversight posts to work for the industry they previously regulated. Prasad and Bien published their findings as a research letter in The BMJ, formerly The British Medical Journal. "If you know in the back of your mind that your career goal may be to someday work on the other side of the table, I wonder whether that changes the way you regulate," Prasad said. "There's a lot of room for interpretation in deciding whether or not a cancer drug should be approved," he said, because so many studies of cancer drugs rely on what's called a "surrogate endpoint." But ... there isn't always evidence that surrogate endpoints are linked to better health outcomes for patients, suggesting that some approved drugs aren't as beneficial as they appear.
