Have seen a number of knowledgeable posters here and on the other board and love it when they post in layman's terms as most are not BIOTECH people.So what one misses or does not feel fully up on is sooner or later covered by another.
That said , in my mind if you have a drug with as you posted - low/no side effects. cheap to make, oral treatment - then you compare that to what is out there NOW being massively advertised with all the warnings , it has to hit you that you have the better drug for patient use even if it only matches effectiveness of those available NOW. And if it proves in trials to be more effective !!! WOW !!! Will have to wait a little longer on that for more confermation in trials.
Even if Leo is NOT SEEKING a partnership on PRURISOL (though I believe he is) a BP would be negligent in not seeking him out. AIMHO
