In this study of biologic-naive Korean patients with Crohn's disease, no significant difference was found in long-term clinical outcomes between those treated with infliximab (IFX) and adalimumab (ADA), suggesting that the selection of biologic treatment can be based on patient and/or physician preference.
Background/Aims: Data on the comparative effectiveness of infliximab (IFX) or adalimumab (ADA) in patients with Crohn's disease (CD) are rare, particularly for Asian patients. We compared the key clinical outcomes (surgery, hospitalization, and corticosteroid use) of use of these two drugs in biologic-naive Korean patients with CD. Methods: Using National Health Insurance claims, we collected data on patients who were diagnosed with CD and exposed to IFX or ADA between 2010 and 2016. Results: We included 1,488 new users of biologics (1,000 IFX users and 488 ADA users). Over a median follow-up period of 2.1 years after starting biological therapy, no significant differences were found between IFX and ADA users in the risks for surgery (ADA vs IFX: adjusted hazard ratio [aHR], 1.22; 95% confidence interval [CI], 0.81 to 1.84), hospitalization (aHR, 1.02; 95% CI, 0.81 to 1.28), and corticosteroid use (a HR, 0.82; 95% CI, 0.56 to 1.19). These results were unchanged even when only patients who used biologics for over 6 months were analyzed (aHR [95% CI]: surgery, 1.31 [0.82 to 2.11]; hospitalization, 1.02 [0.80 to 1.30]; corticosteroid use, 0.80 [0.54 to 1.18]). Additionally, these results were unchanged in patients treated with biologics as monotherapy or in combination with immunomodulators. Conclusions: In this nationwide population-based study, no significant difference was found in the long-term effectiveness of IFX and ADA in the real-world setting of biologic-naive Korean patients with CD. In the absence of trials to directly compare IFX and ADA, our study indicates that the selection of one of these two biologics can be determined by patient and/or physician preference.
