The influential journal National Law Review ran an article on January 20, "How Will Trump Change the FDA," focusing almost entirely on Dr. Scott Gottlieb's positions (here).
Despite the generic headline, the article cites Gottlieb by name 19 times.
At the NIH, Francis Collins is remaining as chief for the time being, and possibly long term. At the FDA, on January 17 a final decision was announced that recently confirmed Administrator Califf was definitely out, putting the FDA's leadership firmly in play for the new administration.
The National Law Review article was authored by Foley & Lardner attorneys Simon Elliott & Courtenay Brinckerhoff.
