kfcyahoo is correct. We tend to think prurisol p2b as a small trial, which it is when compared to phase 3 trials. But for phase 2 it is sizable. Anecdote: look for NCT00954915 in ClinicalTrials.gov. It is p2 psoriasis trial by MacroGenics and Lilly.
kfcyahoo, welcome to lunatic fringe. My spreadsheet has now over 110 p2 and p3 psoriasis trials with results, and it does not include NCT00954915. A person has to have some principles. Besides, that trial did not report PASI75 and sPGA 0/1 percentages which are my inclusion criteria. Did not expect this - there must be some 500 or more psoriasis trials between US and EU registries. I WANT MY SANITY BACK --- Which brings this idea up: I just invented swallowable mouthwash: menthol and zantac infused vodka. I call it BANG: Start your days with BANG! End your days with BANG!
