DRUG COMPANIES CANNOT BE TRUSTED TO RUN CLINICAL TRIALS FAIRLY WITHOUT SAFEGUARDS. This is not a conspiracy theory. I covered the industry @nytimes and saw the internal memos. Even the best companies will hide or try to explain away bad data.
I believe that they are not legally liable for the consequences, which is why I found it surprising that they even paused anything to look into the adverse event. Must have been helluva adverse event (which sadly looks like it was).
