Often bad clinical trial results aren't released because they are bad for reasons other than the drug doesn't work.
Also, it's very rare for big pharma companies to screw up a clinical trial. It's much more common in the small biotechs and non-profits. If there is one thing that big pharma companies are good at is drug development (not so much drug research).
What does that have to do with clinical trials? You're not being logically coherent. The FDA isn't going to approve a drug because someone makes a fake journal and publishes some results in it.
