Stealth Comparative Effectiveness in U.S.

Are you sitting down?

The FDA is practicing stealth comparative effectiveness.

Or at least that's one of the claims to come out of a lively panel discussion that attempted to grade the regulatory agenda of the new leadership at FDA during the first day of The Pink Sheet's annual FDA/CMS Summit.

The discussion was sparked some provocative data released by the Director of the Office of New Drugs, John Jenkins, during his status report on new drug approvals. (You think he only took industry to task for submitting incomplete applications? Guess again.)

In an effort to silence critics who charge the FDA is becoming more conservative, approving fewer drugs because of its safety first initiatives, Jenkins and his team parsed applications data for the past 17 years, looking at the percentage of new molecular entities approved on first action during five-year increments. Here's what they found: NMEs with priority review did pretty well; in the most recent period, 68% of the compounds won approval, up from 58% in the previous time period. But for standard NME applications, the story was far different: 70% of the medicines were not approved on first action.

Calling this failure rate "a huge burden on the system," Jenkins challenged the drug industry to do some more navel gazing. "The industry needs to ask itself why the failure rate [for standard NMEs] is so high," he says.

It's not like execs haven't been asking that question. Perhaps the only issue causing more hand-wringing than comparative effectiveness is the lack of R&D productivity in the industry. That's why folks at Lilly, for instance, are aiming to expand their highly publicized Chorus experiment, which aims to identify earlier--and more cheaply--whether new compounds even have a shot at becoming viable medicines.

Mary Pendergast, the former deputy FDA commisioner and now President of Pendergast Consulting looked at Jenkins' data and came up with one possible answer that takes some heat off the industry. Maybe one reason it's so much harder to get the second, third, fourth, and fifth drugs in a class approved these days stems from FDA's desire to see superiority data. "What we are seeing--and should be paying attention to--is [the emergence of] stealth comparative effectiveness," she claims.

Note that current laws stipulate explicitly that FDA does not have a mandate to practice comparative effectiveness. But in Pendergast's view, the emphasis on superiority data "is a tiny loophole that the FDA is driving a truck through."

Better that than a camel through the eye of a needle, eh?
