I fear that too many see filing MedWatch reports as an inconvenience (at best). Having battled investigators to constantly reinforce the need to report all AEs in clinical trials, I am sure that a significant amount of potential adverse drug reactions go unreported.

This is a perfect example of where the new post-marketing surveillance approved in the FDA bill of last year comes in. Identifying common characteristics among populations as small as 6-in-1000 is exactly what that post-marketing scheme is designed to do. Let's not keep a life-saving drug off the market, but let's also make sure that we monitor it very closely.

This is a similar problem to drugs in which there is a known or suspected pharmacogenetic component to safety and efficacy. The companies know collecting and analyzing the data to help them identify specific populations that will be responders is likely to identify those that have a potential for increased risk. This narrows the target population and, therefor, the sales so companies are hesitant to evaluate this information (even more so prior to launch). We're talking about an industry that finds any way to increase sales and create blockbusters, so the lawsuits and settlements are just the cost of business since the profit margin is still higher with these than it would be if they limited the patient population.

This is a conundrum -- what do you do? The drug clearly helps some people, but it clearly hurts other people. We don't know which group a particular individual will fall into. Rest assured, if the drug is approved, a black-box warning will go on the side of the package warning of the major bleeding complication -- yet Lilly will get sued for $50 million. That's what people do here.... This last sentence you wrote sums up why drug discovery is so difficult:

For investors and industry rivals, an approval is a potentially big deal, because the blood thinner would compete in a huge market and Lilly, like other big drugmakers, needs new big sellers as patents expire on older drugs. Then, there was the question about whether the drug would pass muster with the FDA, given the recent study results, which were very disappointing after expectations were so high. Even if approved, questions may remain about its utility. And after those well-publicized study results, Lilly was on the defensive. So that's why I wrote what I did about their announcement today. Just a little extra context. Hope that helps. And thanks for stopping by. Cheers ed Hi Matt,

Their obviously going to be biased and present only evidence that supports the use of their latest wonder drug. You can bet Lilly pulled some strings through financial ties to the FDA to get a priority review... Who cares what Lilly has to say about it’s own drug?
