On the one hand, they are kind of _forced_ to do research in one form or another to power the pipelines, so clearly corporate research is still alive there.
However, given the pathetic track record the industry seems to hace, and arguably complete lack of any real innovation (almost all of the drugs in most pipelines are just antibodies or their variants), some form of corporate research rot seems evident here as well.
One problem I see often on pharma side is that it's revealing when the CEO of the org is not a technical person. GSK recruited the CEO of L'oreal as its new CEO. TBH I can't for the life of me figure out how someone who sold lipsticks can make decisions on which preclinical trial has the highest chance of success in a human being. If the CEO of a company is not fundamentally versed in the fundamental technology they make can the company actually be successful?
