Sixteen weeks into the treatment regimen, 94% of the patients presented PASI 75 response, 76% PASI 90, and 39% were in complete remission (PASI 100). These results were similar in both study groups.

Mean PASI scores also showed significant decreases from the 11.6 score at baseline, including scores of 6.5 at week 4, 2.2 at week 16, 1.8 at week 28 and 1.6 at week 52 (P < .001 for all).

Among prior PASI 90 responders, 79% (n=117) regained PASI 90 response and 67% of prior PASI 100 responders (n=67) regained a PASI 100 response. [hmicms_related_articles] ...
