That's wrong. They are registered so that they can't hide the data from the FDA. But once the FDA has the data the drug companies aren't required to publish it anywhere, nor does the FDA publish it themselves.
"Could i FOIA FDA on hundreds of clinical studies of well known drugs and publish them online?"
Absolutely, but you would need to pay their costs, which could be several thousand dollars per drug and several million dollars overall. At some level though you probably would need to go to court to win. And even if you were successful, no one would believe you anyway. Books like Goldacre's or reports like this are published all the time, well-researched and true, but they're no match for the billions of propaganda dollars spent by the medical industry and big pharma each year, and the complete ownership of the media, congress, medical education, hospitals, and the FDA.
...Which supports what I said, as only a small number of the studies listed as completed show the results, and even the ones that do don't show the raw data.
Interesting, this is more than I thought was required. But even still, it's much less than the amount of data the FDA actually gets. Not to mention that of the 1508 drugs the FDA has approved since 1940, this only useful for the 50 or so approved in the last couple years.
Also, the last time I heard phase IV trials didn't need to be registered at all, except for when they were required as a condition of approval.
