First, the background: Avandia, also known as rosiglitazone, is an anti-diabetes drug that helps patients control their blood sugar. It made billions of dollars for GlaxoSmithKline until it became associated with higher risks for cardiovascular issues. On Sept. 23, the FDA and European regulators issued their verdicts on the drug. In America, it will still be available, though with much stronger restrictions than before. In the European Union, regulators are looking to stop sales entirely and steer patients toward alternatives.
If you’re looking for the official lines and basic news, start with CardioBrief, where Larry Husten recapped a few of the highlights and then provided each agency’s press release, as well as the official take of Avandia maker GlaxoSmithKline.
Then, it’s time for the reactions. On the NPR health blog, Richard Knox examined the dueling story lines that have emerged since yesterday’s announcements. This larger framework makes all subsequent reactions a little easier to contextualize.
Speaking of other reactions, The Hill‘s health blogger, Julian Pecquet, rounded up the thoughts of some Washington heavy hitters involved in the Avandia debate, from the omnipresent Sen. Max Baucus to the consumer group Public Citizen. Another key player, cardiologist and Avandia critic Steven Nissen, spoke to The Wall Street Journal‘s Alicia Mundy.
In terms of the big regulatory picture, Avandia is the 30th drug which has been restricted under the FDA’s risk evaluation and mitigation strategy provisions since they began in 2007. Merril Goozner says that the FDA has created a new class of drugs. “They are not exactly safe, but not so dangerous that we would deny them to physicians or patients who really want to have them,” he wrote. Five years ago, he said, Avandia would have been pulled from the market. Now, it just gets restricted. It remains to be see how effective those restrictions really are.
Finally, Pharmalot’s Ed Silverman brings us the thoughts of cardiologist and Yale professor Harlan Krumholz, who you might remember from his recent star turn in Forbes. His take emphasized a principle well-known to health journalists: Marketing matters, and often it matters even more than regulation does.
“The company has announced it will no longer promote the drug,” Krumholz wrote, “and the practical result in Europe and the US may be a lot more similar than the decisions at first appear. Usage will stop in Europe and new use should virtually stop here.”
That said, Krumholz raises some interesting questions, any one of which could form the basis of a follow-up story or two. I’ll paraphrase:
- A long series of fortunate coincidences lined up to produce the evidence that led to Avandia’s delayed near-demise, which begs the question: Why are we relying on luck when it comes to spotting danger in major pharmaceutical products?
- “Why does the FDA believe that the barriers to prescription in new users should be stronger than those for current users? There are no studies that indicate that the excess risk dissipates over time.”
- Will the FDA really be able to effectively implement the regulations and guide physician/patient behavior, especially when it comes to a blockbuster such as Avandia?
- Have we done anything to prevent the next Avandia? How do we even go about doing that?
