When is a conflict of interest not a conflict of interest? When it serves the political whims of Senator Charles Grassley. Seems that an FDA employee was removed from an agency review of Wyeth’s heartworm drug Proheart 6 because of possible personal and financial conflicts of interest. (Wyeth voluntarily pulled Proheart 6 from the U.S. market in September 2004, after thousands of reports of serious side effects, and the death of 600 dogs.) According to a Reuters report, the FDA launched a criminal investigation of the employee but took no action. The employee went to visit Senator Charles Grassley, the new father-confessor of disgruntled FDA employees. The result, another outbreak of Mad Corn Disease on the floor of the United States Senate. This dog won’t hunt.
