Long-term persistence and other treatment patterns among bio-naïve patients with Crohn's disease treated with ustekinumab or adalimumab.

Choosing a treatment on which a patient can stay over a long period of time is key for the successful management of chronic conditions such as Crohn's disease. Information on whether and how long patients stay on treatment can help physicians make the right therapeutic choice. This study examined whether adults with Crohn's disease, who have not previously taken biologics, stay on treatment longer when given the biologic ustekinumab or adalimumab. At 12 and 24 months after starting the treatment, a larger proportion of patients were still using ustekinumab compared with adalimumab. The proportion of patients using the biologic without immunomodulators or other biologics was also higher with ustekinumab. The results suggest that patients without previous biologic experience stay on treatment longer with ustekinumab than with adalimumab.
