FDA approves Skyrizi for Crohn's disease.- AbbVie

In two induction and one maintenance clinical trials, Skyrizi demonstrated significant improvements in endoscopic response (defined as a decrease of greater than 50% from the baseline Simple Endoscopic Score in CD [SES-CD] or for patients with isolated ileal disease and SES-CD of 4, at least a 2-point reduction from baseline) and clinical remission (defined as a Crohn's Disease Activity Index [CDAI] of less than 150), compared to placebo, as both an induction and maintenance therapy.

The co-primary endpoints of the clinical trials were endoscopic response and clinical remission. In the 12-week induction studies, ADVANCE and MOTIVATE, a significantly greater proportion of patients treated with Skyrizi achieved endoscopic response and clinical remission compared to placebo. As early as week 4, clinical response (defined as a 100-point reduction in CDAI) and clinical remission were achieved in a significantly greater proportion of patients receiving Skyrizi as compared to placebo. In the 52-week maintenance trial, FORTIFY, a significantly greater proportion of patients achieved the co-primary endpoints of endoscopic response and clinical remission as compared with the placebo group (risankizumab induction responders) after one year.
