Of course I'm serious. The only way to show one drug is superior to another for the same disease is to compare them directly and phase III does not do this. If it did there would never be a head to head drug trial or even non-inferiority trials because we'd already have the data. The comparing that goes on in phase three is does the drug do what it says it does in a similar manner to other drugs - ie does this new inhaler improve patient symptoms subjectively or does this new blood pressure medicine actually lower blood pressure. There is no one getting other meds to compare in any kind of head to head fashion.
You do not understand how statistics work. You also seem to not understand how comparison works.
Phase III compares the efficacy of a new drug to a standard. We agree on this at least, right?
When you compare the performance of things, there are three results you can come up with: They perform equally well, thing 1 performs better and thing 1 performs worse. These are the only logical possibilities that exist here.
The statistics we use for comparison are specifically designed to discern which of these possibilities is most likely. What statistical comparison modality do you know of that will tell you if two things are equal in performance but will not tell you if they are unequal? This makes no sense statistically but it also makes no sense logically. If something can usefully tell you that two things are equal in performance, it must also be able to tell you when that is not the case.
t-tests, ANOVAs, etc. all tell you whether two things are different with respective endpoints.
You say "there is no one getting other meds to compare in any kind of head to head fashion." Sorry, but you're wrong. I know you're embarrassed that you're wrong on this so you're sticking to your guns, but you're wrong. The very quote you gave from the FDA said that Phase III compares new drugs to standards. If I'm wrong about this, how exactly do you compare two drugs in a trial without ever giving anyone one of the drugs? Surely you must see how this is nonsense.
Maybe this site will clear some of this up for you:

Just to quote a selection of what it says in this website of the American Cancer Society:
Phase III clinical trials: Is it better than what’s already available?
Treatments that have been shown to work in phase II studies usually must succeed in one more stage of testing before they are approved for general use. Phase III clinical trials compare the safety and effectiveness of the new treatment against the current standard treatment.
So look: You're wrong. Man up and admit it so we can move on with this discussion. Your hang-up about this is clearly about pride and not about actually knowing you're right.
