A new study in The Journal of the American Medical Association is adding fuel to the fire about Amgen's
Combining clinical trial data from multiple studies -- called a meta-analysis -- showed that Aranesp from Amgen and Procrit from Johnson & Johnson raised the risk of death in cancer patients by about 10%.
I'd liken this meta-analysis to the one recently performed on drug-eluting stents, which actually helped Johnson & Johnson, but hurt Boston Scientific
While the news is old, the companies aren't off the hook yet. An FDA advisory committee meeting on March 13 could result in recommendations to further restrict the use of the drugs in cancer patients.
In the worst-case scenario, the panel could recommend that the drugs not be used in cancer patients, but there's enough evidence that the drugs help reduce the need for transfusions to make a full curtailment doubtful.
It's more likely that the panel will recommend that doctors wait for patients to become more anemic before administering the drugs. That would take a bite out of sales since some patients wouldn't reach the new threshold, but won't do too much more damage than what's already been done.
Until the meeting next month, investors won't know how bad the damage (if any) will be, but a meta-analysis of old data isn't going to change the outcome of the meeting much.
