There is a New England Journal of Medicine "Perspectives" article on this case but the link to it might not work, and so here is a news story. To me this was big news as I recall how, over the long years, people with MS have been keenly aware of the way in which the MS drugs were being marketed. I'm not sure how much difference this settlement news will make in the long run but at least there's been quite a hue and cry in protest against the way doctors have been coaxed into prescribing these very costly drugs.

This is from the New England Journal of Medicine article:
In this case, the relators were former Biogen employees who had overseen physician marketing and so had firsthand knowledge of the programs. The law firm representing them processed millions of documents obtained during discovery and undertook dozens of depositions of Biogen employees over nearly a decade of litigation.
Such voluminous pharmaceutical marketing data have been analyzed in past investigations. But the Biogen case is exceptional for two reasons. First, it focuses on specialty drugs (generally those with list prices higher than $50,000 per year) — in particular, Avonex (interferon beta-1a), Tysabri (natalizumab), and Tecfidera (dimethyl fumarate). Specialty drugs are the most important drivers of profitability in the pharmaceutical industry; relatively few prescriptions for such drugs can generate substantial revenue. Second, the case pertains to the use of expert physicians as consultants to Biogen and speakers endorsing the benefits of its drugs. Many of these consultants and speakers were also high-volume prescribers of MS medications. The marketing programs provided income for these prescribing physicians, thereby potentially enhancing their brand loyalty.

The decision to settle came just before new legislation was passed allowing the federal government to negotiate the prices it pays for certain medications. Much of the opposition to this legislation centered on the fear that lower prices could lead to fewer resources being available for drug discovery. Many pharmaceutical firms, however, spend as much or more on sales and marketing as they do on research.
