This isn't a small company nor is it a minor drug. This is one of the largest drug companies running a trial on one of the most lucrative drugs in the world.

And secondly, why should ANY drug trial be managed by a PR department? When you ask people to risk their lives to be in a drug trial (in the link above the subject died in the trial), why should it be to improve the PR of a drug for one company. The fact that this exists at all is a major warning sign. The indifference of people to this is frankly amazing to me (its even worse than the disinformation provided by the OP).
