Interesting. I haven't read either of the original books so it's difficult for me to evaluate the quality of these papers. It's worth noting though that these papers are only the beginning of a long back and forth, which you can find on Hooper's website:
Also, while clinical trials usually do take 10 years or so, the actual patients don't necessarily receive the drug for more than a few weeks. The reason it takes so long is because you need to do preclinical research, secure patents, secure funding, get IRB and FDA approval for each study, design the methodology and acquire the resources you need, recruit hundreds or thousands of volunteers, wait for the drugs to get manufactured, run all the studies in each phase, analyze the data, get FDA approval to transition from phase I to phase II and from phase II to phase III, then wait for actual approval, etc.
