The three Food and Drug Administration (FDA)-approved anti-tumor necrosis factor drugs (anti-TNFs) for Crohn's disease (CD) have not been directly compared.


To compare the efficacy of the three anti-TNFs for CD in clinical practice.


Retrospective review of patients initiated on anti-TNF between 2004 and 2008. Disease activity, quality of life, and remission rates were compared between groups over 1 year.


Sixty patients with CD were initiated on anti-TNF from 2004 to 2008: 31 on infliximab (IFX) and 29 on adalimumab (ADA) or certolizumab pegol (CTZ). More patients in the ADA/CTZ scores group had prior exposure to anti-TNF (76 versus 10%, p < 0.01). Mean Harvey-Bradshaw Index (HBI) scores in the IFX group were lower than in the ADA/CTZ group at 12 months (2.72 ± 3.34 versus 5.63 ± 5.33, p = 0.03). At 12 months, more IFX patients were in remission compared with those on ADA/CTZ (88 versus 53%, p ≤ 0.01). Mean short inflammatory bowel disease questionnaire (SIBDQ) scores were not different between the IFX and ADA/CTZ groups at 12 months. Stratified analyses and logistic regression based on prior anti-TNF use did not show differences in remission rates at any time point post-baseline between groups.


After adjustment for prior anti-TNF there was no difference in remission rates between the IFX and ADA/CTZ groups at any time point post-baseline. This suggests that differences between groups were accounted for by a higher rate of prior anti-TNF in the ADA/CTZ group. Our results should be reviewed with caution given the small sample size.
