FDA approves Skyrizi for Crohn's disease.- AbbVie
AbbVie announced that the FDA has approved Skyrizi (risankizumab-rzaa) as the first and only specific interleukin-23 (IL-23) inhibitor for the treatment of adults with moderately to severely active Crohn's disease (CD).
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.
