There was a very sad example of this in the last decade.There's a wonderful drug, and a class of drugs actually,but the particular drug was Vioxx, andfor people who were suffering from severe arthritis pain,the drug was an absolute lifesaver,but unfortunately, for another subset of those people,they suffered pretty severe heart side effects,and for a subset of those people, the side effects wereso severe, the cardiac side effects, that they were fatal.But imagine a different scenario,where we could have had an array, a genetically diverse array,of cardiac cells, and we could have actually testedthat drug, Vioxx, in petri dishes, and figured out,well, okay, people with this genetic type are going to havecardiac side effects, people with these genetic subgroupsor genetic shoes sizes, about 25,000 of them,are not going to have any problems.The people for whom it was a lifesavercould have still taken their medicine.The people for whom it was a disaster, or fatal,would never have been given it, andyou can imagine a very different outcome for the company,who had to withdraw the drug.
