Inflammatory bowel disease and Taltz® (ixekizumab)
Ixekizumab is not recommended in patients with inflammatory bowel disease.

Summary
Prescribers should be aware of and follow the appropriate language in local labeling for ixekizumab regarding inflammatory bowel disease (IBD).
Cases of new or exacerbations of inflammatory bowel disease have been reported with ixekizumab. Ixekizumab is not recommended in patients with inflammatory bowel disease.1
If a patient develops signs and symptoms of inflammatory bowel disease or experiences an exacerbation of pre-existing inflammatory bowel disease, ixekizumab should be discontinued and appropriate medical management should be initiated.1
There is no contraindication for the use of ixekizumab in patients with a history of IBD.2
In the ixekizumab phase 3 clinical trial program across psoriasis, psoriatic arthritis (PsA), and axial spondyloarthritis (axSpA), the overall IBD frequency is reported as uncommon (less than 1%) for the placebo-controlled periods.
The exposure adjusted incidence rate (EAIR) as of March 2022 is
Crohn's Disease and Ulcerative Colitis Events in the Clinical Trials
Psoriasis
Per external adjudication, 31 adult patients with psoriasis had reported cases of IBD which were adjudicated as UC (n=18, IR=0.1 per 100 PY) and CD (n=13, IR=0.1 per 100 PY) across 17 adult psoriasis trials (N=6892 patients with 18,025.7 PY of exposure) as of March 2022 (Summary of Adjudicated Inflammatory Bowel Disease Events in Adult Psoriasis Clinical Trials: Frequency and Exposure-Adjusted Incidence Rates (All Ixekizumab Exposures as of March 2022)). Of the 31 patients with IBD events, 20 discontinued ixekizumab treatment at the discretion of the investigator.2,4

dTwenty-six cases were listed as treatment-emergent adverse events of IBD.

Across the 17 adult psoriasis trials, the number of patients who self-reported a history of IBD was 35.
