Skyrizi vs Fumaderm for psoriasis

[Kat]

So... the difference is the point where you act.
Biologicals suppress the cytokines áfter they have been produced by the body.
DMF prevents the cytokines to appear.

Okay so this part I understand. 

I guess there is still confusion and or disagreement within the medical community as to certain things with psoriasis.  The majority thinking that it is an auto immune disease if I understand correctly.  But  Dr. Schweckendieck has a different theory but as of right now it's a theory (based on his studies) right?  Not saying what is correct or incorrect, simply again getting it sorted in my non scientific brain.

But, unless I read it wrong doesn't this study show Skyrizi had better outcomes in their study over DMF?  With DMF you say the "cytokines are less produced and you can imagine that the overactiveness of the immune system slows down and the Psorasis disappears"  But if this study is to be believed, that wouldn't be true of everyone.  Or am I overthinking here?

I think from what I've read more on this forum (including a lot of your information!!) is that DMF works well for some and biologics works well for others.  I don't know if/when/how psoriasis forms but it seems that both are effective treatments just individually one may work better than the other (as in for each individual person).  That's my views on it, but I constantly remind you all that I don't know what I'm talking about
