$70million to get to this stage of having reversed Alzheimers damage in just a 12 week clinical trial is pretty impressive.
"But Alzheimer?s experts worry about the future. The research is extremely expensive ? Lilly spent hundreds of millions of dollars on its failed drug ? and it can take a decade or more to know if a drug works. It can take even longer if drugs are tested in people with mild symptoms of Alzheimer?s disease or in people who are at high risk but have no symptoms yet ? a direction many think is necessary to really make a difference."
