Genentech - the anti-dumb!

Genentech seems to have learned from the vioxx fiasco and is adeptly on top of the PR:

Genentech Inc. warned doctors that people using Lucentis, a treatment for the leading cause of blindness among the elderly, may face an increased risk of stroke.

As I understand it there was already a stroke warning on the bottle, but they decided to send the letters anyway.
