I can see the flaw, no patent, an old drug with no real therapeutic effect as already demonstrated. The only diamond is the hope many have which to date has no hard data or evidence other than what has already been seen from the previous studies ie partial response and some hopeful signs.

So far the only diamond is a hope that dosage formulation will work.....that is why you have trials. But once again many seems to be making their money on the rumor and not the facts. Oh yeah, and one unsubstanited story.
