Pfizer is developing a drug, PF-02341066 -- let's just call it "1066" -- that targets mutated ALK, a mutation that's implicated in several cancers, including non-small-cell lung cancer (NSCLC). Pfizer would like to test the drug only on patients who have that particular genetic mutation in their NSCLC.
Abbott to the rescue. The companies didn't talk specifics on who's paying for what or even what platform Abbott would use to run the test, but it's clearly beneficial for both sides to set up the partnership before the phase 3 trial begins.
As better drugs are developed to treat diseases and the bar for new entrants becomes increasingly higher, drug companies need to figure out a way to show that their drugs are superior. By eliminating from consideration the patients who can't respond to drugs like 1066, companies can increase the average response and thus make their drugs look better.
Clearly developing a companion diagnostic to select patients before the clinical trial begins is preferable to what happened to Amgen
As the cost of DNA sequencing continues to fall, it will become increasingly easier for drugmakers to determine why patients fail to respond to some medicines and respond well to others. That's a win-win-win process for patients, drugmakers and diagnostic-test makers. But if Abbott continues signing up partners, we may have to put its "win" in big, capital letters.
Speaking of CAPS, that's the name of our stock-picking service. Let us know whether you think personalized medicine is the next big thing or just overhyped: Post a pitch about Abbott or one of the other diagnostic test makers at CAPS. It's free. It's fun. And it's Foolish.
