Objectives: Pharmacokinetic processes associated increased drug clearance could play a key role in primary no-responders to anti-TNF drug in inflammatory bowel disease patients. To our knowledge, little is known about whether drug exposures after induction doses are sufficient to avoid pharmacokinetic failure in real life. The main objective of this study was to determine the proportion of patient adalimumab and infliximab-treated, with pharmacokinetic failure at induction period, and to investigate the factors associated with increase clearance.

Methods: We conducted a retrospective observational study. Patients starting treatment with adalimumab or infliximab during May 2017 to June 2021 were potentially eligible for the study. The primary outcome was to determine the proportion of patients with drug concentration at induction period, and to investigate baseline patient-related characteristics affecting to drug elimination. Individual pharmacokinetic parameters were estimate by Bayesian method for each patient.

Results: A total of 101 patients were included in the study. The proportion of patients with serum concentrations in the therapeutic range was higher in patients treated with adalimumab than infliximab (74.5% vs. 40.0%, respectively; p < 0.001). After multivariate analysis, the factors associated with a short half-life (<163 hours) for infliximab were: diagnosis UC (OR: 5.62 [CI95% 1.01 -32.5]), serum albumin (OR: 0.26 [CI 95%: 0.03 - 0.90]), and anti-TNF-ɑ previous treatment (OR: 8.86 [CI 95%: 1.10-71.48]).No association were found for ADA.

Conclusion: The findings of this study justify the early measurement of drug levels to be able to optimize therapy appropriately and avoid lack of response, especially in patients at risk.
