This reminds me of a situation my wife dealt with a few years back. She was on a pain medication that was really the only one she had found that provided the relief she needed to get through the day. But it suddenly stopped being sold or prescribed one day.
That day, the FDA banned the drug. It cited a study that found that the drug was linked with something bad, I think maybe suicidal thoughts.
But then she found that the study was produced by the company that made the brand name version of the drug, which had competition by generics by that point.
Hmm.
Also, the brand name company had just created a new similar pain medication that had new patent protections. The FDA ruling effectively killed the competition of this new drug.
Hmm.
Mind you, that new drug is ineffective for my wife's pain. Also, the study was done over a very short period of time, had a weak sample size, and when you look at its bias, there's no way that study would have made it into a real medical journal. But would the FDA accept it (presumably along with a check with lots of pretty zeroes)? Absolutely.
