You've got to be kidding me. You're pulling our leg.
The PsA study shows that after week 16 40% of patients on a 20mg dose improved had an ACR20 (20% improvement). 35% of patients on a 30mg dose showed the same 20% improvement. After 52 weeks, 30% of patients reached an ACR50 and 20% reached an ACR70.
So, 30% of patients got a bit better. Others got a little bit better. The answer to your question would be that CTIX believes Prurisol works better. But that's just a guess by me, and I'm no doctor like you (and it was from a short reading because I was looking up something fictional as you continually spell the name of the drug incorrectly.) -W
